M-NET.2 - realization of Ethernet-channel systems fire "TIRAS"
Nowadays local computer networks have become an essential part of almost any modern enterprise, company or office. Besides, all these objects are required to be equipped with fire alarm systems.
A common work of fire alarm and LAN provides a number of advantages; they are particularly topical at medium and large objects, as well as at spatially-distributed objects.
«M-NET.2» module, a new development of "Tiras-12" LLC, is designed especially for the use of wide opportunities provided by local networks in "TIRAS" fire systems.
«M-NET.2» has two options of use:
- Implementation of the communication via network (Ethernet) between FCP "Tiras-16.128P" and the expansion devices "Tiras-4P", "Tiras-8P", "Tiras-16P" and PUiZ "Tiras-1" («M-NET.2» must be installed in each device that will operate in the local network).
- Connection of the addressable fire alarm system "Tiras-A" to PC and the organization of monitoring with "Monitor-A" software.
«M-NET.2» is implemented on a separate PCB, it has no separate cashing and should be set inside the housing of FCP, it is connected to the system via RS-485 bus.
«M-NET.2» is addressed in LAN by a static IP-address. If there are two modules on different subnets, subnet mask must be specified. «M-NET.2» is programmed from a PC via a web interface.
«M.NET.2» also enables to transmit data via Gigabit-capable Passive Optical Network (GPON), this technology nowadays gains popularity and is characterized by considerable scaling and extra bandwidth.
So, «M.NET.2» allows you to use network, already assembled on-site and significantly reduce the cost and time spent for buying and mounting new cables.


You’ve probably heard the term “flash” when it comes to cellphones, but what does flashing a cell phone mean?
In simple terms, flashing a cell phone essentially means reprogramming it to work with a carrier other than it’s intended provider. I want to take a quick second to explain the difference between flashing and unlocking. It really comes down to the differences in the main 2 cellular technologies, GSM and CDMA. You can read more about the differences between then in our blog, GSM vs CDMA. Unlocking applies to GSM phones, which is the process of obtaining a code that “unlocks” the sim card slot and allows you to put a different provider’s sim card in place of the original. Some phones come unlocked already, such as our Maxwest lineup.
Flashing, on the other hand, applies specifically to CDMA phones. For example; Sprint, Verizon, and US Cellular all use CDMA towers. Flashing a CDMA phone reprograms the internal software coding to make the phone think it is for a different provider. Some people will ask, this flashing legal? In fact, it is. It is not considered hacking into the phone by any means.
That is not to say that flashing doesn’t have some potential disadvantages. Flashed phones often cannot be reprogrammed for their original carrier. On the other hand, the whole reason to flash is to get on a no contract service that will allow you to cut your bill in half, so why would you want to go back? Another potential side effect of flashing is that certain phones may lose certain features. For example, some phones cannot send or receive picture messages after being flashed. If this is a concern, please speak with a U Wireless professional before flashing your phone to make sure you know all the details. The main other disadvantage to flashing is that flashes can be negatively affected by software updates or factory resets, so you do have to be careful, or you may end up having to pay for a second flash.
Now, in my opinion, the benefits to flashing a phone far outweigh the potential disadvantages. For one, you don’t have to invest in a brand new phone. Right there, you have saved a few hundred dollars. Not to mention the fact that if you are flashing a phone, you are likely going to a no contract provider that will save you a ton of money.
To recap we have answered the question, “What does flashing a cell phone mean?” You are essentially reprogramming the insides of your phone. We can flash Sprint, US Cellular and 4g Verizon models to be compatible with Selectel Wireless and also Pageplus. See our plan page here for more info.


Iceland's first anechoic chamber
The first radio-frequency anechoic chamber in Iceland can now be found in the basement of the RU University Campus. The chamber has been customized for the needs (and budget) of the Engineering Optimization & Modeling Center (EOMC) at RU. It is about 7m x 4m x 3m in size, electrically shielded, and covered inside with aborbers that suppress reflections of electromagnetic waves within it.
The primary purpose of the chamber is measurements of antennas and antenna arrays, in particular, their radiation patterns; however, the chamber can also be used for other purposes such as measurements of electromagnetic compatibility. The chamber will be used by EOMC led by Dr. Slawomir Koziel, professor at RU School of Science and Engineering (SSE). The chamber as well as necessary gear and measurement equipment (e.g., vector network analyzer) has been co-funded by Rannís and SSE, and assembled by Dr. Koziel and his research group members. Parts of the chamber, in particular measurement towers and controls for them, have been designed within RU.
Dr. Slawomir Koziel in the chamber
Anechoic chamber is a facility that is necessary for conducting any serious research in antenna engineering, specifically, for experimental validation of antenna prototypes. It can be found in many universities and research institutes all over the world. “Until now we have had to outsource experimental validation of our antenna designs.
Having the testing facilities here will help us immensely in our research,” Slawomir explains. The chamber emulates (electromagnetically) open space environment which is critical for reliable radiation field measurements. Inside the chamber there are two towers, one containing a reference antenna and the other the antenna under test. The position (rotation angles) of both towers can be controlled from outside to allow fully automated 2D and 3D radiation pattern scans.
The measurements can be conducted in the frequency range from 1 GHz (limited by the physical size of the chamber) to around 20 GHz (currently limited by available measurement equipment, cables, etc.), which covers most of the current needs of Dr. Koziel‘s group.


Thanks to our friend from the US for securing a communication hub
Updated: Apr 17, 2022
Internet connection in Kyiv is unstable. Getting even LTE equipment is complicated, as all the electronics shops are closed. Also even this unstable connection is at risk of going down. One of the first things the Russians do when they enter our cities is trying to destroy big communication hubs to leave Ukrainians detached from each other and the rest of the world.
We are very grateful to a friend from the US for providing us with the Starlink terminal. In the Ukrainian war context it became one of the most robust ways to stay connected.


Design of smart socket for monitoring of IoT-based intelligent smart energy management system
Rao C.K., Sahoo S.K., Balamurugan M., Yanine F.F. (2021) Design of Smart Socket for Monitoring of IoT-Based Intelligent Smart Energy Management System. In: Sekhar G.C., Behera H.S., Nayak J., Naik B., Pelusi D. (eds) Intelligent Computing in Control and Communication. Lecture Notes in Electrical Engineering, vol 702. Springer, Singapore. https://doi.org/10.1007/978-981-15-8439-8_41 (1008.Kb)
Smart socket is designed for collecting and sending the data from the various nodes in one field to other fields. Smart socket consists of the Arduino_Uno, XBee, sensors, gateway, computer, USB, and IDE. This works emphasis on design and development of smart socket with wireless capability, this can be used to collect the data from each electrical device by using sensors. An XBee transmitter and receiver node are used for data communication in wireless networks. Real-time data gathered at the central node can be used to prioritize and schedule the appliances. Then, the system analyzes the data to generate control commands to turn the devices attached to the smart socket on or off. This paper presents the operation and functions of smart socket in different sensor network topologies. The results show that the proposed smart socket can correctly read the data from the various nodes and also send it to different nodes of different parameters.


The ISSI HyperFlash family of products are high-speed CMOS, MirrorBitNOR flash devices with the HyperBus low signal
count DDR (Double Data Rate) interface, that achieves high speed read throughput. The DDR protocol transfers two data bytes per
clock cycle on the data (DQ) signals. A read or write access for the HyperFlash consists of a series of 16-bit wide, one clock cycle
data transfers at the internal HyperFlash core and two corresponding 8-bit wide, one-half-clock-cycle data transfers on the DQ
Both data and command/address information are transferred in DDR fashion over the 8-bit data bus. The clock input signals are
used for signal capture by the HyperFlash device when receiving command/address/data information on the DQ signals. The Read
Data Strobe (RWDS) is an output from the HyperFlash device that indicates when data is being transferred from the memory to the
host. RWDS is referenced to the rising and falling edges of CK during the data transfer portion of read operations.
Command/address/write-data values are center aligned with the clock edges and read-data values are edge aligned with the
transitions of RWDS.
Read and write operations to the HyperFlash device are burst oriented. Read transactions can be specified to use either a wrapped
or linear burst. During wrapped operation, accesses start at a selected location and continue for a configured number of locations in
a group wrap sequence. During linear operation accesses start at a selected location and continue in a sequential manner until the
read operation is terminated, when CS# returns High. Write transactions transfer one or more16-bit values.


I was working with a customer that was using Infoblox and Bluecat. From the research I done, most organizations out there use infoblox for everything network related and don’t divide it between different applications to accomplish the same goal. In this case infoblox handled most of the networking parts ( IP & subnets ) and bluecat handled the DNS part. So to be able to take full advantage of the Nios modules in ansible, you need to create the DNS zones in infoblox. Even if you have the DNS service turned off and don’t use it at all, the module and infoblox depends on it. So you will need to do the following:
Create a DNS zone (localnet)
Create a sub zone (infoblox)
so you will end up with infoblox.localnet and can use the NIOS modules.
[ This will be fixed in the future to be able to use this module without requiring DNS views]


Twelve Major Broadcast Groups to Form Joint Venture to Develop National Mobile Content Service
LAS VEGAS, NV – April 13, 2010 – Belo Corp., Cox Media Group, E.W. Scripps Co., Fox, Gannett Broadcasting, Hearst Television Inc., ION Television, Media General Inc., Meredith Corp., NBC, Post-Newsweek Stations Inc. and Raycom Media today announced plans to form a standalone joint venture to develop a new national mobile content service. Utilizing existing broadcast spectrum, the service will allow member companies to provide content to mobile devices, including live and on-demand video, local and national news from print and electronic sources, as well as sports and entertainment programming.
Broadcast spectrum to be utilized for the new mobile service will come from the three owned-and-operated station groups — Fox, NBC & Telemundo, and ION — and the nine local broadcast groups, which are Belo, Cox, E.W. Scripps, Gannett, Hearst, Media General, Meredith, Post Newsweek and Raycom. Separately, these nine local broadcast companies formed Pearl Mobile DTV Company LLC as a vehicle for their involvement in the venture.
By aggregating existing broadcast spectrum from its launch partners, the new venture will have the capacity to offer a breadth of mobile video and print content to nearly 150 million U.S. residents. In addition to broadcast spectrum, the partners will commit content, marketing resources and capital to the new venture. The service will employ ATSC-M/H, an open broadcast transmission system developed by the Advanced Television Systems Committee (ATSC) specifically for mobile devices.
The venture is designed to complement the Federal Communication Commission’s (FCC) National Broadband Initiative by giving consumers mobile access to video content while reducing congestion of the nation’s wireless broadband infrastructure. In addition, the service’s mobile content network will have the capacity to deliver local and national time-sensitive emergency information to citizens across the U.S.
Regarding the announcement, Jack Abernethy, Chief Executive Officer of Fox Television Stations, stated: “We are excited about building a platform that makes mobile television universally available and economically viable. This venture is the first step in forging cross-industry and company partnerships to deliver content to consumers.”
“This initiative offers a path for the next generation of video consumption, and will help the FCC in its goal of ensuring efficient and reliable broadband service for US consumers,” said John Wallace, President, NBC Local Media.
“Local broadcasters are the backbone of the U.S. media industry,” said David J. Barrett, President and CEO of Hearst Television Inc. “This sharing of content, broadcast spectrum, marketing resources and capital is unprecedented, and underscores U.S. broadcasters’ commitment to bringing vital local news, weather, and emergency information to increasingly mobile U.S. consumers. This is a critically important initiative that holds great promise for our audiences and the television industry. This is truly the next generation of local television service.”
“This venture takes to the next level the work we embarked upon three years ago with the development of Mobile DTV technology, in anticipation of digital TV capabilities and consumer mobile demand,” said Brandon Burgess, CEO of ION Television.
“Mobile digital television places each of our companies at the center of a consumer transformation, putting us on cell phones, netbooks, DVD players and even in-vehicle entertainment systems,” said David Lougee, President, Gannett Broadcasting, Gannett Co. Inc. “And it’s the consumers who are the big winners. From news and entertainment to emergency information, virtually all U.S. consumers will soon be able to bring their most valuable content with them wherever they go.”
Information regarding a dedicated management team that will focus on securing additional content, spectrum and distribution partnerships for the venture will be made available at a later date.

A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear. Unlike hearing aids, which make sounds louder, cochlear implants bypass the damaged hair cells of the inner ear (cochlea) to provide sound signals to the brain.
The cochlear implant technology can help people who:
- Have moderate to profound hearing loss in both ears
- Receive little or no benefit from hearing aids
- Score 50% or less on sentence recognition tests done by hearing professionals in the ear to be implanted
- Score 60% or less on sentence recognition tests done by hearing professionals in the non-implanted ear or in both ears with hearing aids.
Many people have cochlear devices in both ears (bilateral). Listening with two ears can improve ability to identify the direction of sound and separate the sounds one wants to hear from those one doesn’t.
Functioning & Process of a Cochlear Implant
Many people suffer hearing loss because their hair cells in the inner ear or (or cochlea) are damaged. The cochlear implant enables the sound to be transferred to your hearing nerve and enables you to hear.
The process is described below:
- A sound processor worn behind the ear or on the body, captures sound and turns it into digital code. The sound processor has a battery that powers the entire system.
- The sound processor transmits the digitally-coded sound through the coil on the outside of your head to the implant.
- The cochlear implant converts the digitally-coded sound into electrical impulses and sends them along the electrode array placed in the cochlea (the inner ear).
- The implant’s electrodes stimulate the cochlea’s hearing nerve, which then sends the impulses to the brain where they are interpreted as sound.
Benefits of a Cochlear Implant
Many adults with cochlear implants report that they:
- Hear better with a cochlear implant than with a hearing aid
- A previous study has shown that people with a cochlear implant achieve an average of 80% sentence understanding, compared with 10% sentence understanding for hearing aids
- Can focus better when in noisy environments
- Find it easier to have conversations with people across meeting tables, in restaurants and other crowded places
- Reconnect with missed sounds that they could not hear before their cochlear implant
- Feel safer in the world as they can hear alarms, people calling out and approaching vehicles
- Talk and hear on the phone
- Enjoy music
- As per statistics published by Ali Yavar Jung National Institute for the Hearing Handicapped (AYJNIHH) in its 2012-13 annual report, almost 65% of children with hearing impairment are not literate. Less than 1% of these children attain graduate-level education skills and can have a significant negative effect on educational and employment opportunities for these individuals. However, with cochlear implants, children can learn in mainstream environments and communicate with their peers
- Bilateral cochlear implants can help them with everyday situations, including the need to monitor multiple ongoing sound sources in classrooms, playground situations and sports activities; safety becomes an issue when the need arises to avoid moving objects, cross a busy street, etc.

FS-TH9X Upgraded 9CH & 2.4GHz with IA10B 10ch Receiver IBUS SBUS PPM
FS-TH9X 2.4GHz 9CH Upgrade Transmitter with FS-IA10B Receiver has revolutionized the way people experience RC, and now this radio transmitter and Receiver can stand up to the top competitions.
This Upgraded 9 channel with FS-RM003 2.4GHz Module TRANSMITTER’S AFHDS (automatic frequency hopping digital system), is developed by FLYSKY for all the Radio Control model lovers and is patented by FLYSKY at home. The system is specially developed for all the Radio control models, that offers super active and passive anti-jamming capabilities, very low power consumption and high receiver sensitivity. With extreme rigorous testing by engineers and studying the markets for years, FLYSKY AFHDS is now considered to be one of the best systems available in the market.
2.4GHz is the standard of new generation radio system because it has a lot of advantages. Operating at 2.4 GHz puts the radio control out of the frequency range of any ‘noise’ generated by the other electronic components on your helicopters – such as the brushless motor, Electronic speed controller, Servos and any metal to metal noise – eliminating interference and glitching that can affect traditional frequency system.


Beacon is the implementation of the tzip-10 proposal, which describes an interaction standard between a wallet and a dApp.
A dApp impelementing the beacon-sdk can build up a channel and send messages over a peer to peer communication layer to a wallet. This allows for a communication for example of a mobile wallet with a desktop application. The requests of the dApp are sent to the wallet, signed and returned to the application. The
beacon-sdk can also communicate to chrome extensions if compatible ones are installed.
beacon-sdk should allow developers to integrate this functionality with minimal coding, but still be customizable to support more complex flows.
For more information on how to integrate the
beacon-sdk in your DApp, read our Getting Started guide.
To get started, install the beacon-sdk from NPM:
npm install --save @airgap/beacon-sdk
# Upgrading from v1 to v2
Beacon SDK v2 introduces some some breaking changes from a developer perspective, most of the changes are internal, specifically in the communication protocol between dApps and Extensions/Wallets. All major Wallets that support Beacon (tzip-10) have been updated to support both v1 and v2 DApps.
We highly encourage developers to upgrade to v2. Besides stability improvements, the most notable new features are:
- Support for multiple browser extensions (eg. Thanos and Spire)
- Support for mobile, browser and desktop Wallets
- Mobile support via Deeplinking
- Secure and encrypted communication between DApp and Browser Extension
- WalletBeacon.io Source Code is the high-level explanation of beacon and is itself a DApp.
- Beacon Example Source Code is a small sample application built for the sole purpose of showcasing beacon integration.
A list of wallets with support for beacon is available here.


Google Analytics recently stated in a blog post that they will be integrating a system to track telephone and live chat leads into Google Analytics.
Google has teamed up with Mongoose Metrics to allow users to track the offline calls into the analytics tool. Mongoose Metrics provides toll free number and Google Analytics tracks the calls made to the numbers by assigning that number to a hidden web page on your site containing the analytics tracking script/code.
This is what Jeff Gillis from Google Analytics team has to say – “When a phone call to the tracking number is connected, the technology will place a web browser visit to your hidden tracking web page and in this way insert the phone call event back into your Google Analytics account. Each phone call generates a unique visit which is clearly labeled inside of Analytics”.
As far as tracking of live chat, they have teamed up with Live Person. Live Person created a Google Analytics integration that allows users to track conversions after chat and provide the following data:
- The Map Overlay Report which provides the volume and quality metrics of live chat interactions by geographic region
- Provides the sources and keywords that drive interactive chats and thus resulting in conversions
- The Goal Path Report which lists the navigation flow that led to the chats and so the conversion
Are they still missing any offline tracking of leads or conversions?


In the past, lots of research has been already done to analyze wireless networks and distributed networks. Then why we need to do the analysis of wireless networks at regular intervals? This is a very important and fundamental question for any wireless networks research. This is the key and motivating question to my research work. In my opinion, the following factors are the main reasons to carry further research in wireless networks.
- New technologies are emerging (ex. New physical layer technique)
- New applications/demands are surfing (ex. Home networking, Body area networking )
- To provide new solutions to our ever demanding QoS hunger. (ex. More Data rate)
- To increase our knowledge horizon for next-generation networks (ex. Ubiquitous technology)
So, my research works mainly involve the performance analysis of wireless networks and design the new solutions for the same. I am a firm believer in collaborative research as collaboration often brings in new perspectives to address research problems from new angles and helps to produce high-quality research as well.
Along with my traditional research, I have been working on industrial and product-based research where I am focusing on developing products based on RFID/IoT/AI technologies. Recently, I am also focusing on education technology and the development of new tools for the same, for example, remote lab facility, automated quizzes, etc.

Brands need to clearly explain how faster networks will improve life
Lauded as the next big thing in the telco industry for a few years now, 5G has only recently captured consumers interest. This year’s Mobile World Congress featured announcements of a number of 5G-ready phones that will be launched this year by brands such as Samsung, LG, and Huawei. At the same time, mobile network providers have also only just started talking about 5G networks, with pockets of 5G hotspots available in limited locations in the US and South Korea. Most of the discussion thus far has been among industry experts, and the capabilities of 5G for businesses IoT.
When we ran a quick poll in the UK asking what 5G means, a third of respondents did not know what it means for them. Faster download speed is the only key advantage most consumers can recognize. Given that the majority of consumers are able to get most of what they need from streaming and downloads with 4G data speed, telecom providers have a lot to do in convincing people to upgrade. In addition to that, telecom providers are facing a number of road blocks on the route to 5G, including regulatory restrictions, investment constraints, and a slow-growth environment.
To overcome these challenges and create a successful 5G launch, it is imperative for telecom providers to make the consumer benefits more apparent and relevant. As a start, telecom providers should ride on the wave of changing consumer behavior. Over the last few years, we’ve seen a shift in how people consume content and entertainment. Being able to articulate how 5G allows a smoother streaming and faster downloading experience will be a sensible first step in marketing an upgrade for 5G. Contextualizing the environment people can stream and consume content based on the 5G hotspot locations will help to bring it to life for consumers, without creating potential disappointment with limited coverage.
Telecom providers also need to move away from the technical speak, such as “latency” describing how the reaction time between command and response will become imperceptible. Using clear and compelling examples, telecom providers need to show consumers how 5G-enabled IoT capabilities can improve their lives. For example, e-sports has emerged as a new category for which 5G provides excellent functional capabilities. Are there other emerging industries or categories that telecom providers can tap into?
Would other technological capabilities, such as augmented reality be the next frontier to enhance consumer experience? Are there any cross-brand collaborations that telecom providers can participate in, in order to create a name for themselves in the IoT space, which will eventually help the sector to be seen as more than just the “pipe” for communications? To answer these questions, brands should take a human-centric approach through all stages of development, from innovation to marketing and experience management.

IP Route command: Create static routes or Change the default Gateway in Linux — LinuxTechLab
IP route command is an extension of IP command, we have already discussed IP commands in brief in our previous tutorial. IP route command is used to add, delete or modify the Linux system’s routing table.
We basically use the IP route command to create static routes in Linux to specific hosts or to change the default gateway for the Linux system. In this tutorial, we will discuss how we can use IP route command to create a static route & to change the default gateway for the Linux system.
Recommended Read: Bash Scripting: Learn to use REGEX (Part 2- Intermediate) Also Read: IP Aliasing : Assigning multiple IP addresses to single NIC
Let’s discuss some examples for the same.
IP ROUTE Command
1- Check the current routing table
To check the current routing table of the system, we can use the following commands,
Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.10.1.0 0.0.0.0 255.255.255.0 U 0 0 0 enp0s3 Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.10.1.0 0.0.0.0 255.255.255.0 U 0 0 0 enp0s3 0.0.0.0 10.10.1.10 0.0.0.0 UG 0 0 0 enp0s3
We can also use the following command to check the routes,
The assigned system IP for the system is 10.10.1.100 & we can see that the destination is within that range only in the first command output. The second command also shows the gateway for the IP range i.e. 10.10.1.10.
The routing files are located in the folder “/etc/sysconfig/network-scripts/”,
# cat /etc/sysconfig/network-scripts/route-enp0s3
10.10.1.0/24 via 10.10.1.10 dev enp0s3
2- Create a new route i.e. create a new static route
To create a new static route to a new network range, the command will be
# ip route add 10.10.3.0/24 dev en0sp3
And we want this network to route from a particular gateway, the command is
# ip route add 10.10.3.0/24 via 10.10.1.10 dev en0sp3
3- Delete a route
To delete a route command is,
# ip route delete 10.10.3.0//24 dev en0sp3
4- Delete the existing default gateway
To delete the existing default gateway for the system, the commands are
# ip route delete default
Same can be accomplished with route command,
5- Add a new default gateway
To setup a new system as the default gateway, we need to use the following command,
# route add default gw 10.10.1.20
or we can also use the following command,
# ip route add default via 10.10.1.20
6- To reject network packets to a particular host or to a network
We can also use the IP route command to reject network traffic to a particular host or even to complete the network range.
To reject network packets to a single host, the command is,
# route add -host 10.10.2.20 reject
To reject the network packets to an entire network, we can use the following command,
# route add -net 10.10.2.0 netmask 255.0.0.0 reject
We have only discussed some of the important examples of use for managing the routes on our system. Please feel free to send in any questions or queries using the comment box below.

Zenith is best known for the first practical wireless TV remote control, the Space Command, developed in 1956. A box advertising a remote control system often referred to as "Space Command Tuning". The Zenith remote, called the Space Command or Zenith Clicker, was an ultrasonic remote that used hammers hitting aluminium rods within the remote. So no batteries required! These rods rang at certain frequencies – forcing the TV to turn on or off, changing the channel or muting or un-muting the sound. The television interpreted the various tones as commands to switch the channel up or down, mute the sound, or turn itself on or off. The RC was an immediate hit, despite increasing the cost of compatible Zenith sets by a staggering 30 percent!
The original television remote control was a wired version, released in 1950, that soon attracted complaints about an unsightly length of cable from the viewer's chair to the television receiver. Eugene F. McDonald, Zenith President and founder, ordered his engineers to develop a wireless version, but the use of radio waves was soon discounted due to poor interference rejection inherent in 1950s radio receivers. Lead engineer Robert Adler then suggested that ultrasonic sound be used as a trigger mechanism. The buttons struck the rods with a nearly whisper-quiet sound (it earned the nickname 'The Clicker') but it ushered in the era of ultrasound remotes – a method used well into the 1980s.
The frequencies used in the Space Command remote were too high for the human ear to pick up, though they could be discernible to animals such as dogs and cats. There was a story going round at Zenith that during testing, one female lab assistant flinched every time the device was tested, due to her sharp sense of hearing.
The Zenith Space Command looked like a Star Trek prop, with just four protruding buttons – worlds away from today's devices which might crowd several dozen onto a slim rectangle of plastic.
The Space Command 600 was introduced in 1965 and this design was in use until the end of 1972. The 600 had an additional, distinctive feature, it could also adjust color hues.
The ultrasonic sound technology used in remote controles endured until the dawn of infrared in the 1980s.
Some models use the word Commander, for example the Space Commander 300.

Instead of a plastic room key, the system uses the Hospitality Mobile Access app on your smartphone to provide a ‘Digital Key’ to access the hotel entrances and your room using Bluetooth.
At CitySide Hotel the Hospitality Mobile Access app will give you access to:
The Guest downloads the Hospitality Mobile Access app, registers his/her smartphone through the app and allows push notifications.
Approximately 24 hours before arrival, the Guest is invited through a push notification to use a mobile key and start the check-in process.
The Guest receives a push notification noting that they are checked in and the app will update with the room number and the mobile key when the room is ready.
On arrival the Guest can bypass the front desk and go directly to their room.
After ensuring that Bluetooth is enabled, the guest simply holds the smartphone to the door lock, waits for the solid green light and enters the room.
The app is provided by ASSA ABLOY Global Solutions, one of the world’s largest lock and access control providers.
Hospitality Mobile Access allows a true ‘contactless’ check-in. Guests can proceed directly to their allocated room assured of their ability to minimise any unnecessary personal contact.
By using Hospitality Mobile Access the use of plastic keycards is reduced. Each year hundreds of thousands of keycards are discarded around the world, which is an issue the accommodation industry is wanting to address.

View topology - Azure portal Log into the Azure portal with an account that has the necessary permissions. A local-area network LAN whose topology is a ring.
Bridges come in three basic types: Ring Topology Ring Topology: By running PowerShell from your computer. Network topolofy change change source ] In a mesh topology i.
Directly connect LANs Remote bridges: Cellular and PCS systems use several radio communications technologies. Select Download topology to download the image as an editable file, in svg format.
Ethernet hubs and repeaters in LANs have been mostly obsoleted by modern switches. If you don't have a network watcher enabled in the region that the virtual network you want to generate a topology for is in, network watchers are automatically created for you in all regions. In a true mesh topology every node has a connection to every other node in the network.
In the simplest of serial arrangements, one RS transmitter can be connected by a pair of wires to one receiver, forming two nodes on one link, or a Point-to-Point topology.
If the central computer fails, the entire network becomes unusable. For example, a network security group that exists in a resource group other than MyResourceGroup, isn't shown, even if the network security group is associated to a subnet in the MyVnet virtual network.
The entire network depends on a central hub and a failure of the central hub can cripple the whole network. The topology shown in the picture is for the virtual network created after deploying the Route traffic through a network virtual appliance script sample, which you can deploy using the Azure CLIor PowerShell.
Daisy chains[ change change source ] Except for star-based networks, the easiest way to add more computers into a network is by daisy-chainingor connecting each computer in series to the next.
As in the conventional star network, individual nodes may thus still be isolated from the network by a single-point failure of a transmission path to the node. Wireless LANs use spread spectrum technology to enable communication between multiple devices in a limited area.
This topology is mostly seen in military applications. You can also edit node details of map objects and connect network devices manually.
In a star network devices are connected to a central computer, called a hub. If a message is intended for a computer partway down the line, each system bounces it along in sequence until it reaches the destination.
The type of network topology in which a central 'root' node the top level of the hierarchy is connected to one or more other nodes that are one level lower in the hierarchy i. The resources shown in the diagram are a subset of the networking components in the virtual network.
Delivers robust reports Network topology mapper software can provide reports on switch ports, VLANs, subnets, and inventory. View topology - PowerShell You can run the commands in the steps that follow: To do this one or more carrier signals are modulated by the digital signal to produce an analog signal that can be tailored to give the required properties for transmission.
Other protocols have nodes that can both transmit and receive into a single channel e. Modems are commonly used for telephone lines, using a Digital Subscriber Line technology. The network watchers are created in a resource group named NetworkWatcherRG. This lookup table then allows future transmissions to be forwarded to the intended destination only.
If you run PowerShell from your computer, steps in this article require version 5. The following example creates the resource group in the eastus region: Node networking Network nodes are the points of connection of the transmission medium to transmitters and receivers of the electrical, optical, or radio signals carried in the medium.
All peripheral nodes may thus communicate with all others by transmitting to, and receiving from, the central node only. Repeaters require a small amount of time to regenerate the signal. Firewalls are typically configured to reject access requests from unrecognized sources while allowing actions from recognized ones.
Network topology refers to the physical or logical layout of a network. It defines the way different nodes are placed and interconnected with each other. Alternately, network topology may describe how the data is transferred between these nodes.
Tree Topology: This is a "hybrid" topology that combines characteristics of linear bus and star topologies. In a tree network, groups of star-configured networks are connected to a linear bus backbone cable.
May 28, · Network topologies such as bus topology, star topology, ring topology, mesh, tree and hybrid topologies are the layout or structure of a network, that how those computer are connected in a network. The physical topology of a network is the actual geometric layout of workstations.
There are several common physical topologies, as described below and as shown in the illustration. In the bus network topology, every workstation is connected to a main cable called the bus. Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network.
  Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks,  industrial fieldbusses, and computer networks.Network topolofy

Ever stopped to wonder why XLR connectors – at least the ones on microphones – have three pins? Actually, it’s surprisingly simple, and also, if that kind of thing floats your boat, actually rather neat. Here’s a simple explanation that covers over some of the more complicated details of how, but hopefully should make it clear.
In a normal two pin connection (standard 1/4″ jack, etc) lets say our original signal has a voltage V at a particular instant in time. So at that moment we run a voltage of V down one wire, and leave the other (usually the copper shield in the cable) connected to the ground, where it can’t change. The difference between the two is then V, and that’s fine. Except that we’re talking about a low level signal in what could be an electrically noisy environment, such as your stage, with mains cables and lights all over the place. Suppose that the cable is running next to a power cable, and is picking up a small amount of mains noise, say voltage N. In our simple two conductor case, the noise will add to our signal voltage V producing a total signal of V + N. Because the other wire is connected to ground, it won’t (for all practical purposes) pick up the noise, so at the end of the cable we’ll have a signal V + N, i.e. the original signal plus the mains noise.
What about a balanced cable?
The three pins in a balanced connection are hooked up as follows:
- Ground, shielding on the cable
- Hot – positive polarity version of signal
- Cold – negative polarity version of signal
Essentially, what happens is that as the signal is fed to the balanced cable, a negative copy of it is created, and fed to the cold pin, while the positive version is fed to the hot pin. This is pretty easy to do using either a small transformer, or some fairly simple electronics.
Again, let’s say our original signal has a voltage V at a particular instant in time. The hot pin will then be at voltage V, and the cold at -V. Simple enough. At the far end, we can electronically subtract the cold signal from the hot, and get V – (-V), which is 2V. Again, subtracting one signal from another is dead easy – a small transformer or some simple electronics will do that for us – and we now have a signal at the other end of the cable that represents V. (The fact that it’s 2V doesn’t matter at all.)
In a noisy environment, we still pick up noise: the hot wire picks up a noise signal N, for a total of V + N; the cold wire also picks up N, for a total of (-V) + N.
When we subtract these at the end, we get (V + N) – ((-V) + N). If you can still remember your GCSE maths, that translates to V + N + V – N, or, magically, 2V. And the noise… disappears. Neat, huh?
Since microphone signals tend to be very low level, V and N can be quite comparable in size, so running an unbalanced lead for a microphone has the potential to produce a very noisy signal: hence, the balanced lead. Equally, the longer a cable is, the more prone to picking up rubbish it is (ask me sometime about the supposedly balanced multicore that picked up Radio Cambridgeshire!), so it’s worth making sure that long runs to amps or monitors are balanced too.
Why aren’t guitar leads balanced? In all honesty – blame Leo Fender. It’s too late to change now.

Single sign-on (SSO) is a property, where a user logs in with a single ID and password to gain access to a connected system or systems without using different usernames or passwords, or in some configurations seamlessly sign on at each system. A simple version of single sign-on can be achieved over IP networks using cookies but only if the sites share a common DNS parent domain. ---- https://en.wikipedia.org/wiki/Single_sign-on
As the definition suggests, one can imagine that SSO becomes one critical part of the system design and user experience design for complex and distributed system, or for a new application to integrate with the existing connected system. With SSO enabled, a system owner can manage access control at a centralized place, therefore granting users permissions cross multiple subsystem is organized. On the other hand, as an end user, he/she only needs to secure one set of credentials to access multiple resources or to access functionalities whose distributed architecture is hidden from the user.
As we entering 2018, our software becomes more complex and its services become more ubiquitous. Let's use Google's SSO for example to illustrate the demand for a modern SSO:
- A user can sign in with password once for both Gmail.com and YouTube.com
- A user can go to Feedly.com or New York Times and use the "Sign-in with Google" to authorize third parties to access the user's data
- A user can sign in with password on a mobile device to sync all photos or contacts from Google
- A Google Home device can connect to multiple people's Google accounts, and read out their calendar events when needed
- YouTube.com developers can use Polymer as frontend technology, and authenticate with YouTube.com backend to load the content via web services API
You might not realize the complexity of such system to support the modern use cases above until your system needs one, and you need to develop the support. Let's translate the above use cases into SSO technical requirements:
- Support SSO cross multiple domains
- Support Password Grant (sing-in directly on the web), Authorization Code Grant (user authorizes third-party), Client Credentials Grant (Machine sign-in), and Implicit Grant (third-party web app sign-in)
- Support distributed architecture, where your authentication server is not necessary on the same domain or at the same server as your resource servers
- Web services API on resources server can effectively authenticate requests
- No technology lock-in for authentication server, resource servers as well as client-side apps.
- Support a seamless user authorization experience cross different client-side technology (Web, Mobile or IoT), and cross different first-party and third-party applications
Fortunately, we can leverage existing open standards and open source software to implement a SSO for a distributed system. First, we will rely on OAuth 2.0 Authorization Framework and JSON Web Token (JWT) open protocols. OAuth 2.0 is used to support common authentication workflows; in fact, the above 4 types of grants in the requirements are the terminologies borrowed from OAuth 2.0 protocol. JWT protocol is used to standardize the sharing of a successful authentication result cross clients apps and resources servers. The protocol allows resources server to trust a client request without double checking with authentication server, which lowers the amount of communication within a distributed system, therefore increases the performance of overall authentication and identification. For more technical details on how to use OAuth 2.0 and JWT for authentication, please see Stateless authentication with OAuth 2 and JWT - JavaZone 2015.
Regarding to building the authentication sever, where all users and machines will sign-in, authenticate, authorize, or identify themselves, the critical requirement for the authentication server is that this server implements OAuth 2.0 protocol and use JWT as the bearer token. As long as the authentication server implements the protocols, the rest of facilitating features can be built on any technology. I like use simple_oauth module with Drupal 8, because out-of-box, this solution is the whole application, including users, consumers and tokens management. Particularly, I have been helping to optimize the user experience of user authorization process for different use cases. If you are not familiar with Drupal, a particular distribution Contenta CMS has pre-packaged simple_oauth and its dependencies for you.
Once the authentication server is in place, we will implement the protocol and workflows on resource server and client-side apps. This part is largely up to your resource server and client-side technologies you picked. We are building this part of integration with Node.js, Laraval, Drupal 7 and Drupal 8 applications. As the time of writing, we have published the module oauth2_jwt_sso on Drupal 8.
I leave the extensibility, limitation, and more technical details of this SSO solution for the upcoming DrupalCon Nashville session. I will include the session video here in late Apri, 2018.
