•Strong signal up to 75 meters (246’)
•Low noise coaxial cables are no longer required
•Measurements in unclean samples and high humidity conditions
•Models with external replaceable battery, for longer electrode life
•Glass sensor for specific applications
Due to the high resistance of the glass membrane, conventional electrodes require a high impedance measurement system. Inadequate insulation of the connectors and cables result in erroneous readings due to leakage or noise. For conventional electrodes, the lead is therefore limited to typically less than 15-20 meters. HANNA AmpHel® electrodes incorporate a miniaturized amplifier which resolves most of the problems associated with high impedance signals. The amplifier circuitry is located right on top of the electrode and is completely sealed. As a result, a strong, low impedance signal is emitted and ordinary connectors with long unshielded cables can be used. This breakthrough technology provides a stable signal for industrial monitoring as well as a major saving in low noise coaxial cable costs. In some cases, the need for a transmitter is also eliminated, resulting in further cost reductions.
For those applications that have been proven particularly hostile to electrodes, HANNA has developed four types of specialized glass. First is an extremely durable sensor glass for general purpose and industrial use. This glass can withstand the stress of daily use. The remaining types of electrode glass allow continuous monitoring in highly acidic solutions containing fluoride ions, as well as high or low temperature process streams, without significantly reducing the useful life of the electrode.
Electrode body material is glass or PEI, while the junction is cloth or PTFE.

Chat “interoperate” between Yahoo and Msn
I wonder if the decision made in these last days by Microsoft and Yahoo! to allow their respective chat clients to talk to one another has more to do with:
a) The success of Trillian
b) How much MSFT and Yahoo! fear the connection of AOL and Google Talk.
After all, Google owns 5% of AOL and could one day own it all, making their instant messaging tool the market leader.
Yahoo Inc. and Microsoft Corp. said they have begun a limited public test to allow users of the companies' respective instant messaging programs to trade messages with one another. The agreement to work together, first announced last October, marks a long-awaited breakthrough among major instant messaging services, which include AOL's pioneering AIM service, Microsoft and Yahoo, along with more recent upstarts including eBay Inc.'s Skype and Google's Google Talk.
Specifically, users of an upgraded version of MSN Messenger, recently rebranded "Windows Live," can trade messages with Yahoo Messenger, creating the world's largest instant messaging community, with 350 million accounts.
These instant messaging, or IM, systems allow users to type messages to others on their "buddy list" via computers and in some cases over mobile phones. Historically, each provider sought to create "walled gardens" that prevented users of one IM system from talking to users of rival systems.
AOL agreed in December to make its U.S.-market-leading AIM eventually work with, or to use the technical terminology, "interoperate," with Google Talk, but no date has been set to do so. AIM users can already chat with users of Apple Computer iChat system for Macintosh computers. Google and AIM work with various other independent IM projects too.
With the Yahoo and Windows deal, icons will allows users to distinguish which program their IM contacts are using. Yahoo and Microsoft plan to make interoperability between their services broadly available in the coming months.
Consumers have pretty much settled in and defined their preferred IM systems and buddy lists, It does make it easier for many consumers who will need to keep one less instant messaging system up and running now.
U.S. Internet traffic measurement firm Nielsen//NetRatings data shows AIM with 47.2 million users in June, compared with 28.0 million MSN/Windows Live users and 22.5 million Yahoo Messenger users. The unduplicated audience of Microsoft and Yahoo was 43.5 million U.S. users, the survey showed.
Yahoo and Microsoft took issue with these numbers, citing comScore Networks's global figures which showed that Microsoft IM had 204 million users and Yahoo IM had 78 million users worldwide. AIM had 34 million users, the comScore data showed.

It was a piece of C++ coding which the students chose the topic. I wrote a piece of software using RSA to encrypt people's information. The software has no GUI but supported user login and registration.
The project was to design a remove control rover. The rover must be equipped with antenna and sensors for detecting and distinguishing wireless signals such as radio signals and ultrasonic waves. The project finished in May, 2017.
The courses for the 2016-2017 academic year are listed as the following:


The US Air Force wants to beam solar power to Earth from space (video)
Space-based solar energy won’t be just a sci-fi dream forever if things go according to the U.S. Air Force’s plans.
The Air Force Research Laboratory (AFRL) is developing a project called SSPIDR (“Incremental Solar Energy Demonstrations and Research in Space”), which aims to mature the technology necessary to generate and deploy solar energy in space to radiate from the earth.
Such a capability would be a great asset on the battlefield, Air Force officials said.
Connected: The most dangerous space weapons ever
“Ensuring that a forward base maintains a reliable power supply is one of the most dangerous parts of military ground operations. Convoys and utility lines are a prime target for adversaries,” said the spokesman for a new AFRL video on SSPIDR.
“Solar energy on the ground seems to be an attractive solution, but it is limited by the area, the size of the required collectors and the climate,” adds the narrator. “But if the solar panels were in orbit, they could have unrestricted access to the sun’s rays and ensure an uninterrupted supply of energy.”
The AFRL provides for sunlight satellites equipped with innovative “sandwich tiles” that convert solar energy into high-frequency electricity (RF) and radiate it to the earth. Down here, receiving antennas convert this RF energy into usable energy.
The AFRL will not build such an operating system, but it hopes to pave the way with SSPIDR, a series of ground and flight experiments that will help mature the required technologies.
Connected: Space-based solar energy receives key test on the X-37B space plane
For example, an SSPIDR experiment known as the Arachne will test power conversion and blasting in space using a sandwich tile built by project partner Northrop Grumman. Arachne is slated to go into orbit in 2024.
SSPIDR also contains experiments called SPINDLE and SPIRRAL that demonstrate the orbital deployment of a scaled-down version of a power radiating satellite and test ways to keep satellite temperatures within a manageable range.
SPINDLE is scheduled to be launched in Alpha Space’s Materials International Space Station experimental flight facility in 2023, which is to be deployed outside the International Space Station.
And above our heads, research on solar energy is already being carried out in space. The Photovoltaic Radio-Frequency Antenna Module Flight Experiment (PRAM-FX) was launched in May 2020 on board the US Space Force’s X-37B robotic spaceplane.
PRAM-FX does not radiate energy to Earth, but it does help researchers measure the efficiency of converting sunlight to RF from sandwich tiles. And the early returns are promising, as a recent study showed.

New developments for depot fuelling will include the Merridale vLink data transfer cable which makes its debut at the forthcoming Coach & Bus Live 13, being held at the NEC Birmingham.
Designed to speed depot fuelling, vLink is a rugged snap-on and quick release communications cable which enables the fuelling point to automatically authenticate the vehicle being refuelled.
“Vehicle identification is a cardinal security measure for all depot fuelling facilities,” explains sales director, Stephen Hannan.
“Traditionally this has been covered by using smart keys which are allocated to specific vehicles. The primary function of the keys is to allow the fuelling control software to recognise an authorised vehicle.
[quote]We have created a low investment solution that does not rely upon troublesome nozzle mounted reader devices or difficult to install vehicle filler neck coil devices.[/quote]
“Merridale has refined this technology with the evolution of the read – write capability allowing the keys to store and update information such the type of fuel, restrictions on amount drawn and the vehicle mileage at the previous transaction. This has been carried forward with the development of proximity readers and the Datatag readers introduced last year,” says Stephen Hannan.
“For vLink we are using the same technology but the read/write device – a contact plate, is physically attached to the vehicle. The vLink comprises a mating contact plate with a long reach umbilical cable connecting the dispensing control system to the vehicle. In operation it simply snaps on and off after the completion of the fuelling transaction.”
The core enabling technologies have been developed by MIS Fuel Monitoring in conjunction with the University of Wolverhampton as part of a Government sponsored Knowledge Transfer Programme (KTP) tadalafil citrate 20 mg cialis.
“Our experience has shown that fleet operators want a robust tamper proof solution to replace keys, tags or cards that can be lost, mislaid or transferred without authorisation,” says Stephen Hannan.
“We have created a low investment solution that does not rely upon troublesome nozzle mounted reader devices or difficult to install vehicle filler neck coil devices. Direct data transfer is also a more resilient solution to alternatives such as hand held devices and video vehicle recognition systems.”
The vLink solution can be retro-fitted quite easily to the majority of existing Merridale installations. It can also be used concurrently with smart keys and data tags allocated to contractors or short term hire vehicles or during the interim period as the fleet is being converted to use the new system.
Stephen Hannan concludes. “We are very encouraged with interest shown so far and discussions are under way with a number of launch customers. In particular these are in sectors where vehicles do not have ignition keys or in locations that are especially dirty or hostile. Further developments will see the initiation of a dialogue with the vehicle engine management system, enabling the transfer other data by using the vLink.

We are still in an area where Internet speed is slow (we are trying to fix that), so, I’ll be brief. We had a simply awesome day. We visited the village of Abesewa, where the technology center is being built. We met with the Methodist Bishop, the Chief, the Elders and several of the school staff. After being welcomed into the village, we visited the Technology Center, which is making terrific progress. We also met the school children and had a very productive meeting with the Headmaster and two technology teachers. Later, we met with the Bishop and the project managers.
We had an amazing day and Jim and I will give more details when the Internet service is better. )kyinaa. (tomorrow)


The Raspberry Pi is a compact, powerful and affordable single-board computer employed by hobbyist and professionals alike in a wide variety of projects. We’ll be making use of the Raspberry Pi’s GPIO (General Purpose Input and Output) pins to trigger external devices (such as Relays, Microcontrollers, PLCs, etc. ) straight from the Lensmaster timeline.
These pins can be controlled programmatically. We’ll be using them to interface with Relays and other devices.
We’ll be using this ethernet port to connect the raspberry PI to the same network switch as the Robot and computer running Lensmaster.
This port is used to power the Raspberry PI using a USB-C power adapter.

Infrastructure sharing: IT expert tasks telecoms operators on redundancy
Opeyemi Praise, the Team Lead, Network Operations, Cyberspace Network Ltd. has urged telecommunications operators to have redundancy while sharing infrastructure.
Praise told the News Agency of Nigeria (NAN) on Monday in Lagos, that the lack of redundancy while collocating was affecting service provision.
The term redundancy is used to describe telecommunication links that are installed to backup primary resources in case such resources fail.
“We should careful so that we do not use infrastructure sharing to kill needed redundancies.
“As a result of infrastructure sharing in some remote communities, all operators are using only fibre connectivity.
“When there is a fibre cut, the whole community is down because there are no alternatives to support the fibre connectivity.
“Operators can still have their own connectivity and have a ride on the fibre of other operators for redundancy,’’ he said.
According to the team lead, there is still more to be done as some operators are still averse to infrastructure sharing.
According to the Nigerian Communications Commission (NCC), one of the benefits of infrastructure sharing is improved quality of service rendered by telecommunications operators and reducing expenditure for them.
Others include faster time to market for new entrants and thus the capability to focus on customer service and core business.
NCC believed that with infrastructure sharing, operators could achieve competitive tariffs for customers and rollout in less profitable areas.
It further said that infrastructure sharing can control excessive proliferation of towers and mast, which made the skyline untidy, especially for aircraft. (NAN).


If someone calls 911 and does not speak English, they will be transferred to Language Line Services where an interpreter will be able to translate all questions and answers. Using this service ensures there is no delay in dispatching emergency personnel to the location of the emergency and assures that the most accurate information is obtained from the caller.
As required by the Americans with Disabilities Act, Johnson County Emergency Call Center (ECC) 911 is equipped with Text Telephone/Telephone Device for the Deaf (TTY) equipment at every call taking position to assist hearing and speech impaired callers. The TTY/TDD technology is built into the phone system to enable seamless communication with callers who have the need to use a TTY/TDD to communicate. All of our telecommunicators are thoroughly trained in the use of a TTY/TDD, as well as continuously trained throughout the year to maintain proficiency in the use of the equipment.


The continual growth of the Internet has resulted in many organizations paying more attention to the selection of Intranet software for internal communications and information management. Organizations increasingly strive to build up an information service system within their organizational network to service the staff within the organization. Internet Information Services are rapidly being replace by Intranet software solutions and custom Intranets.
Historically the term “Intranet” was used by a small group of people but didn’t gain popularity until 1996. It was known under several names such as Campus Network, Local Internet, and Enterprise Network and became later recognized as an “Intranet” system. In more recent years, “Intranet” has been commonly used and has presently become a very popular jargon within organizations.
It can be said that Intranet usability is to use Internet technology with limitation mainly within an organization. Moreover, Intranet can also offer a connection via Internet which allows users to use both Intranet and Internet at the same time. Generally, Intranet doesn’t handle an outside Internet connection for resources. Instead, information is prepared within an organization under a main computer network that works just like Internet but networked to only the staff of the organization. By doing so, everyone is able to search information and communicate with other people within the network. One of the potential features of Intranet is that the central information service offers accessibility to obtain text, pictures, and videos making it easy to use and share the information. It also includes other information services such as electronic mail, file sharing and transferring, and a news board. Intranets helps adjust the old style organization methods of distributing copies of announcements, reports, internal phone numbers, and personnel data into an electronic format where one can easily access the information whenever they want. The Intranet application for organizations is now seen as a way to reform the organization, improving working procedure for both the present and the future. Intranet software can help manage work procedures resulting in reduction in costs of production and increased efficiency with the selection of matched technology. The Intranet network that connects to the Internet is called Extranet. Extranet can be seen as a part of the Intranet that allows users to connect outside of a local area network by communication through Internet instead of direct internal contact, thereby saving time and expense by connecting users across great distances.

The “Internet of things” (IoT) is becoming an increasingly growing topic of conversation both in the workplace and outside of it. It’s a concept that not only has the potential to impact how we live but also how we work.
The Internet of things is the network of physical objects that contains embedded technology in order for them to communicate and interact with their environments and each other. The Internet of Things is actually a pretty simple concept, it means connecting physical things to the Internet or a network with the help of a computer program. Machine learning is when computers learn in a similar way to humans — by collecting data from their surroundings — and it is what makes IoT devices smart. This data can help the machine learn your preferences and adjust itself accordingly.
The Internet generates an insight of technologies to expand the knowledge of every individual in the society which will help improve productivities and communications across all industries in the world.
IoT devices contain sensors and mini-computer processors that act on the data collected by the sensors via machine learning. Essentially, IoT devices are mini computers, connected to the Internet. The Embedded Technology (ET) Conference & Exhibition introduces advanced technologies and solutions for emerging embedded applications, including digital consumer electronics, automotive, wireless and ubiquitous computing and factory automation.
What is an Internet of Things device?
Any stand-alone Internet-connected device that can be monitored and/or controlled from a remote location is considered an IoT device. With more smaller, more powerful chips, almost all products can be an Internet of Things devices. IoT describes a world where just about anything can be connected and communicate in an intelligent fashion. In other words, with the Internet of Things, the physical world is becoming one big information system.
More devices are becoming network accessible. 50 Billion IP devices will be connected by 20222. Most people think about being connected in terms of computers, tablets and smartphones.
The first Internet appliance, for example, was a Coke machine at Carnegie Mellon University in the early 1980s. Using the web, programmers could check the status of the machine and determine whether there would be a cold drink awaiting them, should they decide to make the trip to the machine.
How will the internet of things affect business and work?
This all depends on your industry: manufacturing is perhaps the furthest ahead in terms of IoT, as it’s useful for organising tools, machines and people, and tracking where they are. Farmers have also been turning to connected sensors to monitor both crops and cattle, in the hopes of boosting production, efficiency and tracking the health of their herds.
Retail: IoT unites data, analytics and marketing processes across locations. Retailers capture IoT data from in-store and digital channels and apply analytics (including artificial intelligence, or AI) for real-time, contextual listening and to understand behavior patterns and preferences. They often use IoT connected devices like RFID inventory tracking chips, cellular and Wi-Fi systems, beacons and smart shelves in their Internet of Things strategy.
IoT connected devices communicate via networks or cloud-based platforms connected to the Internet of Things. The real-time insights gleaned from this IoT collected data fuel digital transformation. The Internet of Things promises many positive changes for health and safety, business operations, industrial performance, and global environmental and humanitarian issues.
Several IETF working groups, spanning multiple Areas are developing protocols that are directly relevant to the IoT. These protocols are used by a variety of companies, as well as IoT standards organizations and alliances, to build and specify interoperable systems. Due to the distributed nature of IoT protocol development and use, there is often need for coordination across different groups working on IoT.
The Internet of Things is predicted to revolutionise the way in which we live our lives, with many industry experts tipping it to have the biggest technological impact since cloud computing, as more data than ever before can be collected, stored and analysed.
The IoT is growing fast, and is set to affect more and more areas of our lives in the years to come, resulting in a smart world that previously was only imaginable in science fiction.
Securing the IoT is one of the big barriers to IoT reaching its full potential. To truly protect the billions of devices entering the field, security needs to be considered at the very beginning of device design.


Power has been restored to all buildings affected by the power outage, said Jim Lowe, associate vice president for facilities, planning and management.
Carmichael Hall, LaFollette Complex, Johnson Complex, the Robert Bell Building, the Ball Communication Building, the David Letterman Communication and Media Building, the Art and Journalism Building, Teachers College, the Applied Technology Building and the L.A. Pittenger Student Center were all impacted, said Lisa Renze-Rhodes, director of media strategy.
The high voltage circuit that supplies power to these buildings faulted a switching vault, Lowe said. The reason for the fault will be determined and repaired.
Facilities were able to restore power by switching the pathway to other circuits that give power to the building, Lowe said.


A global Internet Outage that is affecting thousands of services is currently in effect. It seems that the origin is Level3 / Centurylink which affects not just games, but also internet traffic and even phone services. It is safe to say that people are not happy at the moment.
It seems that this started just before lunch swedish time and reports of network issues started flood in right after that. Popular games suddenly had server issues and the list of affected services on Downdetector grew fast. Centurylink seem to have some serious issues right now as they seem to have somehow manage to break IPv4 and IPv6 making traffic loop without finding their intended destination.
Besides breaking a large portion of services it also seem that their ISP part is also down, causing a lot of people loose their Internet connection. This also affect IP based phone services of course, which could be a big problem.
Based on reports from different sources, such as the Cloud Helix status page it seems that CenturyLink have identified multiple Border Gateway Protocol (BGP) issues causing service impacts across multiple markets. This would explain the IPv4 and IPv6 issues and it is not a total surprise that the now 26 year old protocol would be the cause.
We are still waiting fo the official word from CenturyLink that has remained dead silent about the situation. That is never a good sign, even if it is a sunday and the world in general is a bit crazy.
We hope for a quick resolution and hope everyone affected remain safe and calm.

DALI is a simple and a specific protocol for lighting control, however if you try to make system for customer’s request, DALI is not enough.
Lighting companies like Philips and Osram have a higher system to compensate DALI, but if you try to link lighting systems with other company’s products, such as IoT devices, since Lighting companies system is not opened, it is difficult to develop system by developers freely.
This time, we test Node-RED as an open tool that works with DALI by using DALI to Ethernet gateway.
I would like to introduce this method.
Connection Diagram of Node-RED and DALI luminaires
Following image is the connection diagram of Node-RED and DALI luminaries.
- Raspberry PI is a small computer. This works as a server to running Node-RED. It is connected with WiFi router by LAN cable. (IP 192.168.0.3)
- DALI-Ethernet Gateway is connected with WiFi router by LAN cable and DALI luminaries by DALI line. (IP 192.168.0.22) We use DeeBridge(iLumTech) as a DALI -Ethernet gateway.
- DALI Power Supply is a 18V DC power supply for activating the DALI network, connecting by DALI line.
- DALI Luminare is DALI compliant lighting fixtures. A power supply for lighting is required separately, these are connected with the DALI line. These luminaries have a unique address.
- IPad can display Node-RED editor by connecting to LAN via WiFi and typing IP address (and port number) of RaspberryPI from the browser.
How to send a command to DALI-Ethernet gateway from Node-RED
Setting of TCP output node
Node-RED has a “TCP output node” for output on TCP connection
Put TCP out put node on flow.
Port : 8421
Host : Fill the IP address that you set for your DALI-Ethernet gateway.
How to send DALI command to TCP output node
Following flow is the easiest sample.
What we want to do is ” All luminaire light max level.”
DALI command is following
TO what : Broadcast all
Command : Recall Max Level
Now I will show how to make flow of Node-RED
Put “Inject node” on the flow.
Double click the “inject node”, and set properties.
Select string for Payload
We want to send DALI command as “Broadcast all : Recall Max Level”, so you type “#255,5” in Payload form.
Connect each node by a wire.
You need one more node for “turn off all luminaries”.
Put “Inject node” on the flow.
“Turn off all luminaire” command is “#255,0”. You put this on Payload form.
Following is a complete flow.
If you push “Broadcast all: Recall Max Level”, all light will turn on, push “Off”, all light will turn off.
What can be done on the Node-RED side
Since DALI is a very simple protocol, there is no function to judge when multiple conditions overlap, it is necessary to have the other system above DALI, like Philips and Osram have.
Node-RED is open source, and DALI is open source, too.
So complex settings and logics for control are made on Node-RED by yourself, you just send DALI commands to the DALI-Ethernet gateway, you can make more optimized plan for your customer freely without restriction from a manufacture.
Possibility of Node-RED with DALI
Lighting is just one of facilities. To build a space, we have other facilities like air conditioning, sounds, videos, securities and etc.
So far, we had faced a trouble that the facilities were different, the manufactures were deferent and we had to ask to develop gateway to the manufactures for expensive cost.
But now, you can use Node-RED as an open source to connect digital information to facilities.
Actually, you can find some library, such as DMX, KNX and Modbus. You can use them and develop system by yourself.
I believe a big change for control facilities have been just started.


A Video Receiver (VRX), is a device designed to receive and decode video signals wirelessly transmitted from a Video Transmitter (VTX). VRX units are commonly used in various applications, including FPV (First-Person View) systems, surveillance, broadcasting, and remote monitoring. Here's a closer look at Video Receivers (VRX):
Key Characteristics and Functions:
Wireless Video Reception: VRX devices are equipped with receivers that can tune into specific radio frequencies used for transmitting video signals. These frequencies are often in the 5.8GHz or 2.4GHz bands, although other frequency bands may also be used depending on the application.
Signal Decoding: The primary function of a VRX is to demodulate and decode the received video signal. This process involves converting the wireless signal into a format that can be displayed on a monitor, screen, or FPV goggles.
Compatibility: VRX units are typically designed to be compatible with specific video transmission systems or standards. Compatibility ensures that the receiver can work seamlessly with the corresponding video transmitter.
Antennas: VRX devices often come with one or more antennas to capture the transmitted signal effectively. Antenna selection and positioning can significantly affect the quality and range of the received video.
Frequency Channels: Many VRX units support multiple frequency channels, allowing users to switch between different channels to find the strongest and clearest signal. This is particularly useful in FPV applications, where video quality and signal strength are crucial.
Diversity Reception: Some advanced VRX systems feature diversity reception, which involves using multiple antennas and receivers to improve signal reception, reduce signal dropouts, and enhance overall video quality.
Display Output: VRX units typically have output interfaces like HDMI, AV (audio-video), or USB for connecting to monitors, screens, or FPV goggles. The decoded video signal is then displayed on the connected device.
FPV Flying: FPV drone pilots use VRX units to receive live video feeds from their drones' onboard cameras. This allows them to fly the drone from a first-person perspective, enhancing control and providing a more immersive flying experience.
Surveillance and Security: In security and surveillance systems, VRX units receive video signals from cameras placed at remote locations, enabling real-time monitoring and recording.
Broadcasting: Broadcasters and video production teams use VRX systems to receive video feeds from remote cameras or sources for live broadcasts or filming.
Remote Monitoring: VRX devices can be used in various industries for remote monitoring and data collection, including agriculture, environmental research, and industrial inspections.
Video Receivers (VRX) are essential components in wireless video transmission systems, enabling users to access real-time video information from remote sources. The choice of a VRX depends on the specific application requirements, including the frequency band, signal range, and compatibility with other equipment.

It was reported in the Star newspapers that a company related to Astro i.e. Measat Broadcast Network Systems Sdn Bhd and another company, Tele System Electronic (M) Sdn Bhd have been sued by AV Asia Sdn Bhd.
Reason for the legal suit brought up by AV Asia - that AV Asia's technology in reducing the existing problem of rain fade (a situation where the satellite transmission suffers interruptions during rain) was somehow used for the benefit of another company i.e. Tele System. Tele System has subsequently produced the satellite dishes purportedly catering for the Astro B.yond's HD channels.
In reading the news article, I saw the following para:-
"AV Asia also alleged that Measat withheld information from its Astro B.yond customers - who bought a new decoder and a new satellite dish for a monthly payment of RM20 to receive HD programmes - that they did not need to install the new dish to receive the programmes."
What did Measat hide from us (the customers)? That we do not require a new dish actually and therefore, the extra RM20 supposedly for the dish and decoder need not be paid?
This is what I want to know being a Astro B.yond customer!

ANR MULTIPAS » MULTI‐gas and multi‐source Photo Acoustic Spectroscopy Measurement Platform » (2017-2021)
Institut d’Electronique et des Systèmes (Aurore, PI), L’UNIVERSITE DE MONTPELLIER
Laboratoire de Physicochimie de l’Atmosphère (Weidong Chen, Tong Nguyen Ba, Eric Fertein), ULCO
Résumé (non confidentiel) du projet en anglais
The MULTIPAS project aims to study and develop a multi-gas / multi-laser sensor, based on tunable lasers photoacoustic spectroscopy, dedicated to ambient air sensing and quantification, as defined by the project end-user, Environnement SA. Even if sensors with high sensitivity already exist, they are limited with some specifications such as : single-gas sensors, very cumbersome, complex to use and maintenance needed, complex calibration …. The proposed sensor will provide equivalent or much better performances in terms of sensitivity and selectivity, but for a much smaller footprint and addressing several gas species simultaneously, which is a major technological breakthrough.
The high performances required for optical sensors with low cost can be achieved by using resonant quartz photoacoustic detection technique (QEPAS, Quartz Enhanced Photoacoustic Spectroscopy). MULTIPAS proposes technology progresses both in the development of laser sources and in QEPAS spectrophone, paying significant efforts on compacification of optical sensing platform and electronic boards. 5 partners are involved, 2 are academic and 3 are industrial partners: the IES, the LPCA, MIRSENSE, VALOTEC and ENVIRONMENT SA.
Semiconductor laser sources (emitting between 2 and 10 μm, single-frequency, high power) will be provided by the IES and MIRSENSE, and implanted by MIRSENSE on a SiGe platform to integrate several sources addressing different gases at different wavelengths on a single chip. This step is the first technological breakthrough that will be achieving for the first time an hybrid multi-source component (SiGe/GaAs/GaSb). Individual sources may initially be supplied to laboratories working on the development of the QEPAS measurement technique. QEPAS offers the advantage of being a simple, compact, yet highly sensitive and selective. IES and LPCA will work on the development and optimization of the QEPAS setups, first with individual sources provided by the IES and MIRSENSE, and then with the SiGe integrated source. The compacification of the whole system without losing the sensitivity combined with a simultaneous measurement of various gaseous species is another technological breakthrough. VALOTEC will be responsible of the electronic maps implementation for various needed functions for the laser sources operation and the QEPAS signal processing.
Environnement SA will qualify the developed sensor by comparative measurements of single-gas sensors.

Voice bots are an emerging technology that is rapidly making its way into the business world. It is an interface that can interact with people using natural language. In other words, it is possible for them to converse with humans.
Voice bots have been around for quite some time, but recently there has been a surge of interest from businesses looking for ways to automate customer service interactions.
In this article, we will discuss the basics of voice bots and how they can be used to add value to your business.
Table of contents
What Are Voice Bots?
A voice bot is a computer programme that interacts with humans using natural language. This means that they are able to have a conversation with people in a natural way.
Thanks to technologies such as machine learning, sentiment analysis and Natural Language Processing (NLP), voice bots are able to pick up people’s intentions and emotions during a conversation. This information can be used to improve the bot’s ability to predict future queries.
Voice Bots Will Perform Repetitive Tasks For You
The value of voice bots lies in performing certain repetitive tasks without losing the brand humanity of a conversation.
This means they can be used for specific functionalities such as booking appointments, updating customer records or resolving frequently asked questions. By having a bot handle these common activities, it ensures that human workers allocate their time to more complex and difficult queries.
Voice bots are not here to replace human workers, but to enhance the customer service experience.
For example, a restaurant could use voice bots to reserve tables for customers. This would free up valuable time for employees, who could focus on providing personalised service.
Voice Bots Are Available 24 Hours A Day
Voice bots are available 24 hours a day, which means they can be used to enhance the customer service experience.
For example, voice bots could be used by a business as an alternative way of receiving feedback from customers rather than waiting for them to log in and call or email your business.
This is especially useful if you have customers in different time zones.
Voice Bots Humanise Your Brand
There is a big difference between clicking on a website, receiving an email or having a conversation. As you can imagine, the fact that your customer can speak to resolve their queries, make a purchase or receive assistance makes your business seem more human.
When a customer can communicate with a company using natural language, the brand acquires a sense of humanity. This is because it feels like they are talking to another human, rather than talking to a machine.
In addition, voice bots can be used to collect customer feedback. This is useful because it allows companies to get feedback in real time, rather than waiting to analyse different metrics.
This is very interesting because it helps to create a connection between the customer and the company. It also makes the customer feel appreciated and valued.

In modern software development, one of the most important considerations is the exchange of data between different systems. In distributed systems, data exchange often occurs through remote procedure calls (RPCs). While traditional RPC methods like XML and JSON are widely used, they can be inefficient and slow. This is where protocol buffers and gRPC come in.
Protocol Buffers is a language-agnostic, binary serialization format developed by Google. Protocol buffers are designed to be fast, small, and simple. They are typically used to exchange structured data between systems or for long-term data storage.
Protocol buffers use a language called the Protocol Buffer Language to define the structure of the data being exchanged. The Protocol Buffer Language is similar to IDL (Interface Description Language) and allows for the definition of message types, which are then used to serialize and deserialize data.
The protocol buffer format is highly optimized for performance and compactness. It is up to 10 times smaller than XML and up to 3 times smaller than JSON, making it a more efficient way to send data over the network.
How Protocol Buffers Work
- A Protocol Buffer file is created that defines the structure of the data to be exchanged.
- The Protocol Buffer file is compiled using the Protocol Buffer compiler, generating code in a variety of programming languages.
- Data is structured according to the generated code and serialized into a binary format using the Protocol Buffer serialization format.
- The serialized data is sent over the network.
- On the receiving end, the data is deserialized using the Protocol Buffer serialization format and converted into a data structure according to the generated code.
- The application processes the received data.
gRPC is a high-performance, open-source RPC framework developed by Google. gRPC uses protocol buffers as its serialization format, making it highly efficient and fast.
gRPC allows developers to define a service in a protocol buffer file and generate client and server code using the gRPC compiler. gRPC supports multiple programming languages, including C++, Java, Python, and Go.
One of the key advantages of gRPC is its support for bi-directional streaming. This means that both the client and the server can send and receive data at the same time, enabling real-time communication between systems. gRPC also supports load balancing and flow control, making it a great choice for large-scale distributed systems.
Protocol Buffers and gRPC are powerful tools for efficient and fast data exchange in distributed systems. While they can be more complex to implement than traditional methods, the performance gains and flexibility make them a valuable addition to any modern software stack. As distributed systems continue to grow in complexity, we can expect to see even more adoption of these technologies in the future.

Brit telecoms regulator Ofcom has kicked off a session over proposals that might see each cellular networks and Wi-Fi customers have entry to frequencies within the higher 6GHz band, if acceptable mechanisms will be agreed to make it work.
Based on Ofcom, the higher 6GHz band, protecting frequencies within the 6425-7125MHz vary, is presently “a spotlight for trade curiosity” within the lead as much as the World Radiocommunication Conference (WRC) held by the Worldwide Telecommunications Union (ITU) later this yr.
A lot of the exercise facilities on approaches that might see the frequencies given over to unique use both by high-power licensed cellular customers, or low-power licence-exempt makes use of resembling Wi-Fi, says Ofcom.
Nevertheless, the UK regulator reckons that with the rising demand for spectrum from a spread of recent and present companies, it’s changing into more durable to justify awarding bands for the unique use by a single software. It believes another method is feasible which might enable each cellular and Wi-Fi to make use of the higher 6GHz band, even when in comparatively shut proximity to one another.
Ofcom is proposing that hybrid sharing approaches might be adopted to allow a couple of software to make use of these frequency bands, and if profitable, the identical might be prolonged to different frequency bands now being thought of for future purposes, such because the 7-24GHz and THz ranges being floated for 6G networks.
A technique of doing this might be to benefit from the completely different utilization traits of cellular and Wi-Fi, Ofcom says in its session doc. For instance, Wi-Fi entry factors are usually deployed indoors, whereas cellular base stations are situated outside, so it might be attainable to help the indoor use of Wi-Fi within the higher 6GHz band whereas additionally permitting licensed cellular use of it outside.
Alternatively, a geographical sharing mannequin might be adopted, whereby cellular community use of the higher 6GHz band might be licensed for particular high-traffic places while permitting Wi-Fi use elsewhere.
However hybrid sharing would require using mechanisms to handle coexistence between the completely different applied sciences, which on this occasion means Wi-Fi and cellular networks. Ofcom units out a number of of those in its session doc, together with using managed databases to specify the place and when entry is allowed, and modifications to channel sensing mechanisms.
Within the latter case, Wi-Fi already makes use of channel sensing to detect if different nodes are transmitting, however has not been designed to detect cellular alerts. An enhancement of present protocols could enable for coexistence between Wi-Fi and cellular, Ofcom claims.
The UK regulator additionally notes that the higher 6GHz band is already getting used for different companies, resembling mounted wi-fi hyperlinks, and there’ll seemingly be coexistence challenges with these that must be addressed so as to help any hybrid sharing scheme.
Ofcom acknowledges that such mechanisms may also have to be supported in additional territories than simply the UK, saying in its doc that “worldwide harmonization is essential to create economies of scale” in a means that might be unlikely for UK-specific necessities.
Earlier this yr, cellular trade physique the GSMA published its personal report outlining how essential the 6GHz band is for the way forward for cellular communications. It stated on the time that governments world wide must “take into account fastidiously” what probably the most environment friendly use of 6GHz spectrum shall be, and even claimed that deployment of 5G within the higher 6GHz band could be essential for nations that need to “maximize the socio-economic advantages” delivered by cellular communications.
Nevertheless, that ship could have already sailed, because the Federal Communications Fee (FCC) within the US opened up your entire 6GHz band from 5.925 to 7.125GHz for unlicensed use again in 2020, largely pushed by calls for to make extra bandwidth obtainable for Wi-Fi. Ofcom adopted its lead by opening up the decrease 500MHz of the 6GHz band.
The FCC provides low-power Wi-Fi for indoor use the unrestricted freedom of your entire 6GHz band, whereas customary energy purposes that function outside should achieve this below the management of an automatic frequency coordination (AFC) system that manages spectrum entry to make sure they don’t intervene with legacy companies that also function within the 6GHz band.
Ofcom is searching for suggestions from “ stakeholders” on each the precept of hybrid sharing and on the practicalities of its implementation, and a kind is available from the regulator’s website to submit responses, which have to be delivered by 15 September.
The regulator stated it intends to observe up with an additional session in 2024 on particular proposals for the implementation of hybrid sharing within the higher 6GHz band. It will take the responses to this session into consideration, in addition to ongoing harmonization work with different related worldwide our bodies. ®

- ItemMultipath Exploitation in Emitter Localization for Irregular Terrains,(Společnost pro radioelektronické inženýrství, 2019-06) Dalveren, Yaser; Kara, AliElectronic Support Measures (ESM) systems have many operational challenges while locating radar emitter’s position around irregular terrains such as islands due to multipath scattering. To overcome these challenges, this paper addresses exploiting multipath scattering in passive localization of radar emitters around irregular terrains. The idea is based on the use of multipath scattered signals as virtual sensor through Geographical Information System (GIS). In this way, it is presented that single receiver (ESM receiver) passive localization can be achieved for radar emitters. The study is initiated with estimating candidate multipath scattering centers over irregular terrain. To do this, ESM receivers’ Angle of Arrival (AOA) and Time of Arrival (TOA) information are required for directly received radar pulses along with multipath scattered pulses. The problem then turns out to be multiple-sensor localization problem for which Time Difference of Arrival (TDOA)-based techniques can easily be applied. However, there is high degree of uncertainty in location of candidate multipath scattering centers as the multipath scattering involves diffuse components over irregular terrain. Apparently, this causes large localization errors in TDOA. To reduce this error, a reliability based weighting method is proposed. Simulation results regarding with a simplified 3D model is also presented.
- ItemA General Hybrid Precoding Method for mmWave Massive MIMO Systems,(Společnost pro radioelektronické inženýrství, 2019-06) Xie, Yi; Li, Bo; Yan, Zhongjiang; Fan, Jiancun; Yang, MaoRecently, hybrid precoding architectures have been proposed for the purpose of practical implementation of massive Multiple-Input Multiple-Output (MIMO) systems in the Fifth Generation (5G) networks. In this paper, a general precoding method is investigated for Millimeter Wave (mmWave) multi-user systems, which is composed of the designs in analog Radio Frequency (RF) and digital baseband matrices. In the general hybrid architecture, the analog part is constituted of independent analog sub-arrays with full connection inside. The analog precoding matrix is considered by maximizing Signal-to-Leakage-plus-Noise Ratio (SLNR) with only the long-term statistics of user groups. Due to the constant module constraint of RF chains, a supplemental matrix is introduced to reduce the performance loss. The digital precoding matrix performs Regularized Zero-Forcing (RZF) with the reduced amount of effective channels. Finally, simulation results demonstrate the performance improvement of the proposed precoding method. Meanwhile, trade-off between the performance and the complexity is handled well by the proposed method.
- ItemThe Digital Audio Broadcasting Journey from the Lab to Listeners - the Czech Republic Case Study(Společnost pro radioelektronické inženýrství, 2019-06) Zyka, KarelThis paper describes the complex experiences and the results of the Digital Audio Broadcasting (DAB+) implementation in the conditions of the Czech Republic. It analyses the background of the EUREKA 147 program, its targets, and to what extent they were reached. The main focus is concentrated on the evaluation of the real steps which had to be done during the implementation process before the first regular broadcasting could be started and the difficulties encountered. The key point became experimental broadcasting “DAB Prague”. It demonstrated the advantages of this new platform and gave the opportunity to test its functions and physical behavior in real conditions, under the different parameter settings. The important issue is the allocation of the band III by National Regulatory Authority and the capacity of DAB+ multiplexes. The paper also demonstrates the experience from the setup of the DAB+ headend. It describes the content solution in context of using non-entropic audio coding, setting the codec algorithms and the way to use accompanying multimedia services. The results of the tests and measurements presented in this paper were used in the real project of the regular nationwide DAB+ network.
- ItemCoplanar Waveguide Microwave Sensor for Label-Free Real-Time Glucose Detection(Společnost pro radioelektronické inženýrství, 2019-06) Sameer, Mustafa; Agarwal, PoonamIn this work, a~real-time label-free microwave diagnostic approach using Co-Planar Waveguide (CPW) design has been demonstrated for glucose detection. This mechanism has tremendous potential for the biomedical applications. Here, glucose biosensor is implemented with 50 Ω CPW transmission line, where the centre localized 3 mm diameter of CPW transmission line has been used for the sensing. Glucose sensor is implemented utilizing low cost multilayer PCB and polymer Poly-Di-Methyl-Siloxane(PDMS) fabrication technology. CPW transmission line is fabricated on FR4 microwave laminate board. To confine the Analyte Under Test (AUT) on the sensing area, PDMS polymer cavity is configured in the centre of CPW transmission line. The electromagnetic interaction with the varying dielectric constant of Glucose:DI water solution results shift in S11 parameter, which is closely observed to use as the source of sensing. CPW based glucose sensor is experimentally measured for S11 parameter using VNA, with varying glucose concentration range from 0 mg/ml (only DI water) to 4 mg/ml with the interval of 1 mg/ml. The measured results showed good sensitivity of 108.4 MHz/mg/ml and high accuracy with good linear regression coefficient of 0.9979.
- ItemEfficient Cycle Frequency Acquisition of a Cyclostationary Signal with the FACA Method(Společnost pro radioelektronické inženýrství, 2019-06) Hu, Yi; Yu, Baoguo; Deng, Zhixin; He, Guodong; Zhou, HaijunThe cycle frequencies of a cyclostationary signal can be used for the signal identification and classification, separation of the overlapped signals in cycle domain, and so on. Efficient cycle frequency acquisition depends on the fast measurement of cyclic autocorrelation function (CAF) or spectral correlation function (SCF) of the signal. Presently the relative efficient CAF and SCF measuring methods mainly include the cyclic correlogram, the well-known fast Fourier transform accumulation method (FAM), and so on. Motivated by these methods, a new efficient cycle frequency acquisition method which integrates the fast Fourier transform (FFT) algorithm with the autocorrelated cyclic autocorrelation function, named FACA, is presented. With the presented method, we can acquire the cycle frequencies of a cyclostationary signal more efficiently with a given level of reliability. Meanwhile, by enlarging the FFT window width of the FACA method we can get the same cycle frequency resolution as the benchmarked method FAM, but the computation cost still can be spared at this case.
