Presonus has released an exciting new line of Live Sound Reinforcement Speakers that they are branding under their StudioLive flag. These speakers all feature “Active Integration” which is a proprietary networking system that allows all the components of your StudioLive Mixer and Speakers to communicate with each other.
Active Integration is a Wi-Fi based networking system for communications, wireless networking, and control of the vast amounts of DSP found in a specialized custom chipset built into each speaker, resulting in a system that can easily detect, manipulate, and control each component of the system in the network enabling the room to be tuned and manipulated from one position.
The StudioLive Active Integration system includes more DSP power physically built into each speaker than a standalone rack mount speaker management system. The included USB Wi-Fi LAN adapter enables wireless networking via a small USB dongle on each speaker. This gives you an unprecedented amount of control over individual speakers through the network, which can be manipulated from anywhere in the room via a laptop, iPad, or iPhone and iPod touch for monitor controls.
StudioLive Room Control
SL Room Control is speaker management software that allows you to interface directly with your entire system via a laptop or iOS device. All you need to do is create a local area network using a wireless router and connect your StudioLive AI speakers with the included USB 2.0 Wi-Fi LAN adapter or onboard Ethercon connection. You also connect your laptop or iPad to the same Wi-Fi network and launch SL Room Control and your free to use a plethora of EQ and dynamic presets, RTA and SMAART applications as well as monitor temperature, set delay time and phase for your entire StudioLive AI speaker system.
Designed by David Gunness, formerly of EAW and Electro Voice, the SL series speakers sport a coaxial design. This means the tweeters are set in the same axis occupying the same space. In actuality the tweeters fire directly through the dust cap of the midrange drivers with the aid of an external wave guide. Without getting too technical, the coaxial design of these speakers results in a homogenous wave pattern from the same source throughout the speakers frequency response. Non coaxial, component based speakers have asymmetrical dispersion patterns that can result in varying phase anomalies dependent on the position of the observer.
StudioLive 18sAI offers the benefits of Active Integration, including remote control—including wireless control—over output level, user-adjustable contours, and more and uses 32-bit floating point DSP for the variable crossover, dynamic limiting, and excursion limiting.
A compact, powered, full-range, 3-way loudspeaker, StudioLive 312AI relies on a 12-inch ferrite woofer for low frequencies and a custom-designed, 8-inch coaxial speaker with a 1.75-inch titanium compression driver to reproduce the mid and high frequencies. These transducers are driven by a hefty 2,000W RMS of triamplified, Class D power.
The StudioLive 315AI is perfect for large venues and bands that need full-range speakers with plenty of low end. The StudioLive 315AI provides 3-way coverage, with a 15-inch speaker for low frequencies and a custom-designed, 8-inch coaxial speaker with a 1.75-inch titanium compression driver to reproduce the mid and high frequencies. These transducers are driven by a hefty 2,000W RMS of triamplified, Class D power.
A 3-way system that features dual 8-inch ferrite woofers and a coaxial 8-inch ferrite midrange speaker and 1.75-inch compression driver, the StudioLive 328AI delivers full-range, high-powered performance, yet is streamlined and compact. These transducers are driven by a hefty 2,000W RMS of quad-amplified, Class D power.
To get the most out of your Presonus AI System you need to use an accurate reference microphone to measure the tonality of the room your tuning your system to. The PRM1 can handle up to 132 dj SPL and has a linear frequency response 20Hz-20kHz, enabling you to take advantage of the RTA (real-time analyser) units and software like SMAART and Virtual StudioLive.

I recently encountered a mail flow problem in an Exchange 2016 environment, that was being caused by the DNS configuration on the Exchange server’s network interface.
The Application log of the Exchange server was flooded by event ID 9041:
Log Name: Application
Source: MSExchange Assistants
Date: 10/6/2016 4:56:46 PM
Event ID: 9041

at Microsoft.Exchange.Assistants.Base.CatchMeIfYouCan(Boolean translateToPermanentException, Action function, String nonLocalizedAssistantName, ISet`1 permanentExceptions)
Looking into the network settings led me on to the root cause; the network adapters DNS settings was misconfigured and included an external DNS server:
I removed the external DNS entry, so only the internal domain controller and DNS server was used.
After rebooting the server all mail flow errors was resolved, and the Application log cleared up again.
Remember, Exchange relies heavily on internal Active Directory and DNS services to support many internal services, including routing and mail flow.


Basically a rectifier converts AC power to DC, and a rectanna converts microwave power to DC. It’s like “rectifier” and “antenna” combined, hence the name “rectanna”.
I always wanted to have a dipole based rectanna on hand, when I explain circular polarisation to someone. And I have designed a very simple microwave rectifier with RF Schottky diodes bat62 from Infineon long ago, but hesitated to make the PCB. Untill recently JLCPCB offered $1 pcb prototyping for 2 layer board within 10cm by 10cm.
Here is the schematic of the microwave rectifier. It is basically a voltage doubler, but use RF diode instead. The source will be replaced with a dipole to form a full rectenna. The load resistance R1 mimics a LED.
Simulation shows that the input impedance does not change much if the capacitance C varies between 47pF and 100pF, and load resistance R1 varies between 30ohm and 1kohm.
The antenna is modified from a RFID antenna ( Alien 9662), and has been opted to match the rectifier. The loop like structure is a T-match trace to tune the input impedance of the antenna.
Antenna simulation shows good impedance match around 920MHz, which falls into North American UHF RFID band (905~928MHz). In the above figure, S11C represent complex S-parameter, which is referenced at the rectifier input impedance instead of standard 50ohm.
Altium was used to build the full circuitry and antenna, and below is the schematic. The antenna was represented with a shorting wire. Diode is bat64 with sot143 package from Infineon. The diode is just a normal 0805 LED, green works better if you ask (Green always looks brighter with same current).
Here is what the PCB looks like, it is 0.8mm FR-4 board. Since JLCPCB’s offer is within 10cm by 10cm, so I placed two in a row. And you can download the Gerber file here.
To test the rectenna, a Motorola RFID hand held reader was used to send the microwave signal (30dBm output with a 3dB circular polarized antenna). Although the diode rectifier is not very efficient the reader signal can still light up the LED even after 1 meter away.

BitPath Voices Its Support for Revising the FCC’s SFN Rules
By John Hane
June 15, 2020
On Friday, BitPath filed comments supporting the FCC’s recent proposal to give broadcasters more flexibility to deploy single frequency networks, or “SFNs”. SFNs allow broadcasters to improve their coverage in areas that otherwise might be under-served or unserved, such as at the edge of the contour or in the shadows of mountains or other terrain features.
The higher and more uniform signal levels we can achieve with SFNs will allow BitPath to respond to growing demand for broadcast data services. Higher power translates directly into more capacity. BitPath’s comments explain why we need the greatest possible flexibility to design and choose tower sites for our SFN networks in order to provide the greatest amount of capacity for long-term growth of data services, and to allow broadcasters to improve service to their communities.
This FCC proceeding is part of a long-overdue rethinking of the rules that control use of the frequency spectrum allocated for broadcast television. For years, virtually everyone in the spectrum business, and most regulators in Washington, has understood that the fat tomes of mid-20th century broadcast regulations were blocking innovation in the most valuable portion of the entire radiocommunications spectrum. But instead of removing or revising those regulations, the FCC simply reallocated the broadcast spectrum for wireless mobile services. The moment the FCC reallocated the spectrum – and freed it from the ancient broadcast technical rules – its utility and its value grew exponentially. That former television spectrum is now the backbone of all of the major wireless carriers’ networks.
The FCC’s arcane and long-outdated regulations have choked tens of billions of value out of the spectrum broadcasters use. Now the FCC is finally taking steps to allow broadcasters themselves to innovate and participate in the mobile and wireless revolutions. The first major step was the FCC’s 2017 decision to allow broadcasters to use ATSC 3.0 (instead of an outdated 25-year-old government-mandated technology). Now the FCC is proposing to allow innovators like BitPath to have more flexibility to build sophisticated broadcast data networks that rely on single frequency networks. BitPath fully supports this effort.
In a rare unanimous vote, the five FCC commissioners have recently started what promises to be the biggest step of all – a wide-ranging review of its broadcast rules with an eye towards eliminating unnecessary regulations that hamper innovation. The public deserves the best technology and services their valuable spectrum can support, and broadcasters deserve the chance to provide them.


Introduction: What Are Embedded Controls & Systems?
In the world of industrial and factory automation, systems acquire data through inputs, process these inputs using some algorithmic functions such as Math and Logic, and output some data or commands to peripherals. Such systems are further capable of interfacing with other ‘systems’ via networks (serial, parallel, Ethernet etc.) utilizing shared protocols such as Modbus, Canbus, Fieldbus among others.
These systems are often referred to as Distributed Control Systems (DCS), Programmable Logic Controllers (PLC), Programmable Automation Controllers (PAC) or Supervisory Control and Data Acquisition systems (SCADA) among other names.
Further these systems utilize high level programming interfaces such as ladder-logic, function block diagrams (FBD) and Sequential Function Charts (SFC) among other common schemes. Many of them meet the standards published under IEC 61131-3.
So, how are Embedded Controls and Systems different from or similar to these systems? At a very basic level, a system comprises of inputs, a processor that performs math and logic functions and outputs that can drive final control elements. To that extent, an Embedded Control System is very similar to traditional control systems.
Where these systems differ are:
- An embedded system is generally built on a single board microcontroller or processor with a barebones operating system, real-time operating system or no operating system, depending on the application.
- An embedded system does not have any firmware or control package pre-installed. Everything is customized to the specific needs of the application.
- An embedded system is typically programmed using a high level programming language such as C, C++ or C# and does not include any support for more traditional frameworks such as ladder logic or FBDs.
- An embedded system can support any and all communications interfaces and protocols with custom code.
- An embedded system can typically provide better performance because of reduced overhead on the processor. Further, many embedded systems include an FPGA on-board which makes data signal processing easier and efficient.
- Generally, embedded systems are lower cost, particularly for small or unique applications where a larger commercial system would not be a good fit.
- Finally, embedded systems are ideal for applications such as machine controls and single unit operations.
- Embedded systems are also ideal for Industrial Internet of Things (IIOT) applications where small, efficient custom processor boards with minimal connectivity is required.
Embedded Controls And SIL4 Systems
SIL4 Systems brings decades of experience in Embedded Systems and Controls to help you design and implement the perfect solution for your specific data acquisition or control needs.
SIL4 Systems has commercial embedded systems built on industry standard form factors such as VME and PC104.
Custom form factors can be designed, as necessary.
Processor – FPGA
The main CPU typically includes a high speed processor and an on-board FPGA with the processing load shared between the two using custom firmware. For safety assured applications, multiple processor boards can be combined with cross-check redundancy to meet a desired SIL level. For SIL4 assurance, a diverse processor system would be applied.
Depending on the processor and the application, the system could have a minimal OS, a full OS, a real-time OS or no OS. Traditional OS’s like Windows and Linux are easily supported on most platforms.
Most processor boards have some on-board RAM with a solid-state drive for the OS/Application. Depending on the board design and application, an external solid state drive can be supported for full extensibility.
Most traditional types of inputs and outputs are natively supported. These include Discrete, Analog and Pulsed Inputs. Similarly, most types of outputs are also natively supported such as Discrete and Analog. Other output types such as PWM can be easily added.
Most boards support multiple communications interfaces such as serial, including RS-232/485, USB, Canbus and others. Ethernet connectivity is also included in the main board including support for Gigabit Ethernet. Power over Ethernet can be supported on a custom basis.
WiFi, 4G-LTE And GPS
Wireless Ethernet, 4G-LTE cellular and GPS interfaces can be added, as necessary.
Typical applications for embedded systems include, among others:
- Machine control
- Retrofit systems
- Custom SCADA systems
- Custom event/data recorders
- Remote I/O systems
- Custom interfaces to third-party systems
- OEM (proprietary) machines, processes and applications


Re: W6JHB: OSB and Quisk on RPi
James Bennett <w6jhb@...>
. . .
Forgot to mention - Quisk and the OSB are at least partially speaking the same dialect, as when I change bands on the Quisk panel, I can hear the relay in the OSB click, so that was a good sign. Also, when I keyed my CW paddle, the green LED on the OSB started flashing, so,it WAS going into transmit. However, monitoring the frequency that Quisk was set to via my Elecraft K3, no RF was going out to the antenna, nor did Quisk display any signals on the band.

let’s understand open source Ngrok. First, we have to understand what is Webhook, let’s go to the beautiful tech journey.
WebHooks: Webhooks are a way that apps can send an automated message to other applications. For example when someone pays you with the help of any payment app so how that app tells your accounting app. How Twilio routes phone calls to your number many more.
The general term “Open source” refers to something that can be modified because of its design publicly accessible means allows to end-user and developer not only to see source code but modify it as well. It is developed by GitHub.
What is Ngrok:-
It is multiplatform tunneling, reverse proxy software that establishes a secure tunnel from a public endpoint such as the internet to locally running network service while capturing all traffic for detailed inspection and reply. (Tunneling is a protocol that allows for the secure movement of data from one network to another).
Ngrok is a cross-platform application that enables developers to expose a local development server to the Internet with minimal effort. The software makes your locally-hosted web server appear to be hosted on a subdomain of ngrok.com, meaning that no public IP or domain name on the local machine is needed. Similar functionality can be achieved with Reverse SSH Tunneling, but this requires more setup as well as hosting of your remote server.
Ngrok can bypass NAT Mapping and firewall restrictions by creating a long-lived TCP tunnel from a randomly generated subdomain on ngrok.com (e.g. 3gf892ks.ngrok.com) to the local machine. After specifying the port that your web server listens on, the ngrok client program initiates a secure connection to the ngrok server and then anyone can make requests to your local server with the unique ngrok tunnel address. The ngrok developer’s guide contains more detailed information on how it works.
Ngrok can bypass NAT Mapping and firewall restriction by creating a long-lived TCP tunnel from a randomly generated subdomain on ngrok.com to local machine. After specifying the port that your webserver listens on, the ngrok client program connects to the ngrok server and then anyone can request your local server with a unique ngrok tunnel address.
There are many tunnel servers available around the world and locations include the US (Ohio), Europe (Frankfurt), Asia (Singapore), and Australia (Sydney). Alternatively, the ngrok server software can be self-hosted on a VPS or dedicated server.
One most important feature of ngrok is the ability to track and reply to HTTP requests via ngrok’s web console (accessible on http://127.0.0.1:4040/). The reply functionality is highly useful when testing API calls or webhooks as one can easily inspect all header content and request or response data in one place via the console UI.
Real-time Ngrok Usage in Vmoksha (A Case Study)(According to MR. About Uday Kiran)
After using Ngrok, MR. Uday Kiran had addressed all the requirements. Here is the following of how he had used the features of ngrok In his scenario he used ngrok in windows.
As this is a small 9MB executable(.exe) tool we can be generally executed with Ngrok command followed by the port no which has to be exposed as follows,
This gives a random subdomain on Ngrok.com and it’ll be accessible over both HTTP and HTTPS (Secure).
Running Multiple Tunnels Simultaneously:
We are using an extensive feature of Ngrok i.e., we can run multiple tunnels simultaneously and a few tunnel configuration is shown in the following YML configuration file.
Sample XML code for running multiple tunnels simultaneously (.yml file)
We can start all four tunnels simultaneously by using Ngrok start command followed by the names of the tunnels we want to start:
The Output Terminal will look something like this:
Request inspection with the Web Interface:
Web Interface is accessible on http://127.0.0.1:4040 using which we can inspect all the http traffic requests over the tunnel. We can also replay them to make the debugging quicker and easier.
Sample Web Interface for HTTP Traffic Inspection:

ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer.

FIBRE-OPTICS AND COMMUNICATIONS [Part-I]
With the technological advancement of the world towards progress and modernisation, there is a strong need of fast and uninterrupted communication. Thin hair-like optical fibres are continuously playing an extraordinary role in the growth of world-wide communication. They are spreading like neurons over the whole planet connecting people to communicate among each other within seconds irrespective of the distance between them and making life easier and faster.
WHY ARE OPTICAL FIBRES SO GOOD FOR COMMUNICATIONS?
Some of the advantages of optical fibres over conventional wires are as follows:
- Economic—Production of optical fibres is much cheaper as compared to conventional wires like that of copper wires.
- Corrosion free—Optical fibres do not conduct electricity due to which they are resistant to corrosive degradation and signals can be transferred even in harsh weather conditions like lightning storms.
- Higher information carrying capacity—The information carrying capacity of optical fibres is much greater than conventional wires because they transfer electromagnetic waves which having frequency of around two hundred trillion cycles per second. Moreover, they have very small diameter which is comparable with a hair strand because of which they can be bundled ina large amount than other wires and hence larger information can be transmitted.
- Less information loss—Since information is being transferred in the form of electromagnetic waves in an optical fibre because of which the loss of signal in optical fibre is less than in copper wire.
- Non-interference of signals—Light signals from one fibre do not interfere with those of other fibres in the same cable which is not possible in case of conventional wires. This allows clearer and uninterrupted communication.
PHENOMENON THAT MAKES OPTICAL FIBRES SO SPECIAL: TOTAL INTERNAL REFLECTION
Optical fibres operate on the phenomenon of Total internal reflection to transmit signals from the source to the receiver. The total internal reflection causes the light rays to reflect back after striking the boundary of the medium in an attempt to refract from optically denser medium to the optically rarer medium. The minimum angle of incidence which is required for complete bouncing back of light rays within the medium is known as critical angle.
COMPONENTS OF AN OPTICAL FIBRE
The important components of an optical fibre are:
- CORE—The innermost part of an optical fibre is known as core of the fibre. It is made up of glass combined with silica. All the electromagnetic signals enter the fibre via core. The refractive index of core is comparatively greater than clad which enhances the ability of signals to bounce back into the core after striking the boundary of the core-clad interface at an angle greater than critical angle.
- CLADDING—The core of the optical fibre is surrounded by another layer made up of combination of glass and silica. It has refractive index slightly lower than the core. Light rays travelling through the fibre core reflect off this core-cladding interface when they travel through the fibre by total reflection.
- BUFFER JACKET—The outer covering of clad is known as buffer jacket. It is usually made up of plastic. It acts as a protective covering of core and clad.
- OUTER JACKET—The outer jacket surrounds the cable to protect the fibre against scratch, solvents, and other pollutants.

Dealing with the next wireless mic apocolypse
Posted on Jul 24, 2015 05:26 am
Eat Spam before it eats YOU!!!
Member Since: May 11, 2002
I run sound at a church and do some events that use a couple wireless mics all in the 500mhz and 600mhz frequency bands. We dodged the previous auction but the 600mhz band is the one we use with our Audio Technica ATW-somethingsomething wireless mics.
I was wondering what the future of wireless mics looks like? Are we going to some sort of local network audio? How reliable are those? ...and what are some good devices/brands? Or other solutions?
My concern with the 2.4ghz mics is that it apparently only allows for 80 something-ish networks, which sounds great... but that frequency range includes wifi and bluetooth which will frequency hop.
[ Back to Top ]
Jul 29, 2015 08:18 am I have been sort of interested in this since open mic night a year or two ago when the hosts sat and mixed the sound system from the bar, on their ipad, while having a drink.
How cool is that? Wireless mics, transmitting to some interface that the iPad controls the volumes of...pretty neat.
There are now (and have been for a while) recording apps for iOS and Android, networked devices, bluetooth devices...but you are right, would 2.4 and 5 gHz suffer due to interference or collision?
Still, it's a neat technology that is pretty cool to see develop.

There are some times that you need to send a message to your contacts and the signal on your mobile phone isn't available. Since we users have grown dependable on our network connection, FireChat tries to change that current tendency by enabling offline messages thanks to the use of the Wireless Mesh Networking. Created by Open Garden, this free app changes the rules of the game about communicative programs offering additional options for granting that your texts are properly sent.
The functionality of FireChat is really similar to other communication applications, where you can simply write short messages to your contacts. FireChat also includes a Nearby mode in which you can write to people who are 30 feet or less from your location, without the need to be connected to the Internet, in a similar way to former Bluetooth messaging systems. You can talk with several contacts at the same time or in a private window for individual chatting.
FireChat includes a Nearby mode in which you can write to people who are 30 feet or less from your location, without the need to be connected to the Internet
FireChat works well, it's free, and it is growing exponentially amongst Android and iOS users. Due to the way it works, this chatting app requires a fast rate of growth to improve it's effectiveness, and according to its developers, the future of the application is bright and promising. The FireChat download in your smartphone device will allow you to connect to your contacts in a different way.
How it works
Communication technologies change with the times. In the Internet age, there are some times when you're not able to access any Internet connection. For this reason, both Apple and Google are trying to avoid these kinds of situations by including an additional way to maintain communication on their systems, called Wireless Mesh Networking. If you ever have used a Walkie Talkie, the way it works is very similar.
FireChat communicates with other devices through a multipeer framework. This allows creating hyperlocal networking systems, without using the Internet for communicating between several devices at the same time. To send messages to a mobile phone that is further than 30 feet away, the connectivity system will use other devices to deliver your message instead of an Internet connection with its multi-hop mesh connecting technology.
This system has overwhelmed their creators due to its success. The only point we can find against it is that it is very dependent on other devices, which first needs to create a strong network by downloading FireChat and only then can they use the app as a bridge to other mobile phones. Both Android and iOS devices are not compatible without an Internet connection since the Mesh Networking protocols are not supported. For the moment, the proposal is interesting; its growth rate is quite strong, and we think it has a bright future “burning” the rest of the messaging applications we depend on.
FireChat 1.4 Features
Check the main and important features of FireChat:
- Chat offline with your contacts using other devices as intermediaries with Wireless Mesh Networking
- Use the service without any having to use Facebook, email or other kinds of information to login
- Use Nearby Chat to send messages to close devices and start chatting with everyone around you
- iPad and iPhone support and additional Android-compatible devices
- Battery usage is kept low so you won't consume it quickly like other similar software
For further details about FireChat, you can check the developer’s official website.
Check the minimum requirements for FireChat on your device:
- Operating System: Android 2.2, iOS 7 or later
- Size: 5MB of free space


The most commonly asked question involved the PTT antennae located on the eagles’ backs. Could they be removed or shortened? How do the transmitters work and why are they the length they are? This blog attempts to answer those questions. Warning: it requires a fair amount of reading and has a long resource list at the end!
Can you get rid of the antenna?
We cannot. An antenna is needed to transmit data from the PTTs worn by our eagles. The PTT and GPS units from Geo-Trak Inc. collect and encode data about location, heading, speed, time, activity, and transmitter and battery performance. The encoded data is supplied as energy to the antenna, which radiates it as UHF radio waves to the Argos satellite network orbiting 528 miles (850 kilometers) over our heads. From there, ground stations receive real time data from the satellites and retransmit it to regional processing centers where we can access it. No antenna = no data.
Why can’t the antenna be smaller? Couldn’t it be part of their leg bands?
Let’s start with a quick primer. When we talk about radio waves, we are really talking about a small part of the electromagnetic spectrum - the range of all types of electromagnetic radiation (EMR). EMR is classified by wavelength into radio wave, microwave, terahertz (or sub-millimeter) radiation, infrared, the visible region that we perceive as light, ultraviolet, X-rays and gamma rays.
International Telecommunication Union coordinates the shared global use of the radio spectrum, which includes assigning radio frequency allocations for space communication. 399.9 - 403 MHz is the band that ITU has allocated for navigation, positioning, time and frequency standard, mobile communication, and meteorological satellites. Geo-Trak’s satellite tracking products use the Argos satellite network, which transmits and receives data at 401.650 MHz (± 30 kHz). Argos is using the highest frequency available to them.
So why does frequency impact antenna size? The wavelength of a frequency is the distance an electromagnetic wave travels to complete one cycle. As the image at right shows, a 401.664 MegaHertz signal (a signal that oscillates, or moves through a complete cycle 401.664 million times in one second) has a full wave length of 29.38 inches, a half wave length of 14.69 inches, and a quarter wave of 7.34 inches.
For the antenna to radiate properly, it needs to match either the full wave or one of its major harmonics. Therefore, 7.34 inches – a quarter wave - is as short as the antenna can be and still function. Perhaps improvements in materials, circuitry, and/or manufacturing will someday allow smaller antennae to be used in satellite tracking, but for now, a whip antenna is our only choice for robust ground to space communication.
I found the distance traveled to be quite fascinating. If you do the math, 29.38 inches (the distance it takes for our signal to complete one cycle) multiplied by 401,664,000 cycles per second equals roughly 186,000 miles per second. It takes a lot less than a second for messages to travel from the Dynamic Duo (D24 and D25) to the Argos satellite system 528 miles overhead.
Will electromagnetic radiation of an antenna hurt the eagles?
No. Terms like electromagnetic radiation are frightening, but not all electromagnetic radiation is harmful. Innately dangerous electromagnetic radiation is found in the high-frequency end of the spectrum, since high frequency waves are a lot more energetic than low frequency waves. Think of it this way: gamma rays have frequencies of 1 x 1021 Hertz, which means that the wavelength crests, or hits its highest potential energy point, 1 sextillion times or cycles per second. That packs a punch! By contrast, visible light has a frequency of around 5 x 1014 (500 trillion cycles per second), microwaves have a frequency of 1 x 1010 Hertz (ten billion cycles per second), and our radio waves have a frequency of 4 x 106 (400 million cycles per second).
Power is also a factor. I have a 1500-watt microwave oven that can damage living tissue. However, it is literally almost 7000 times more powerful than the 225mW solar units that power the transmitter. Even cellphones produce radio waves that are more powerful and energetic than ours.
What about insect studies? Those antennae are really small!
A lot of really cool work is being done with insects. While some of the technologies involve active transmitters, which require batteries, others use passive devices like RFID tags and geolocators. Passive devices don’t require much power and can be made extremely small. A couple of links:
- How microtransmitters help solve nature’s riddles: http://www.popularmechanics.com/science/animals/a5005/4342060/
- Scientists put backbacks on dragonflies to track their brains in flight: http://www.wired.com/2013/06/dragonfly-backpack-neuron/
The tiny little transmitters used in tracking insects are very cool – check out that tiny backpack! – but they have short battery lives (7-21 days) and a limited tracking range on the ground only (100-500m). As neat as they are, they aren’t suitable for tracking juvenile and sub-adult eagles either.
We can’t get rid of the antenna, which is as short as it can be given the frequency of our ground to space transmission. Argos did a great job designing a package that is light, safe, reliable, and trackable almost anywhere on earth, especially given the physical requirements of the transmission system. The transmitters do not harm bald eagles or impact their social or reproductive interactions with eagles that aren’t wearing transmitters. Passive devices aren’t a good option since juvenile and sub-adult eagles range unpredictably and often widely before settling down to nest, while tiny active devices have short battery lives and a limited ground-only tracking range – something that won’t work for animals that can fly hundreds of miles and live relatively long lives.
However, research into insects and small birds is driving tracking devices to become even smaller. If at some point appropriate tracking hardware becomes available with a smaller antenna, we will use it.
Did you know?
The wavelength and frequency of electromagnetic waves are closely related. If you have a frequency, you can get the wavelength, and if you have a wavelength, you can get a frequency. With the wavelength, you can determine the length of the antenna you need to transmit or receive radio waves at a given frequency. The formula looks like this: Wavelength = Wave speed/Frequency.
Let's say that I have a frequency of 401.664 MHz, or 401,664,000 cycles per second. The wave speed is the speed of light, which can be expressed as 3x108 m/s or 300,000,000. If I divide 300,000,000 by 401,664,000, I get .7468 meters. Since I was raised in the English system, I immediately convert it to inches or feet, which gives me an antenna length of 29.38 inches. This was very helpful when trying to determine why the antennae on our PPT systems are the length they were. This web calculator provides lengths for half and quarter wave antennas if you want to play around with making them: http://www.csgnetwork.com/antennagenericfreqlencalc.html
What could you do with an antenna? There is a community of people that listen to the earth via homemade VLF radios. This website provides an introduction to the concept and some online streams: http://abelian.org/vlf/

CDN, Content Delivery Network
CDN, Content Delivery Network, consists of a set of networked computers across the Internet which cooperates to make content or data permanently available to end users. Whether it’s a content management system or custom applications, a CDN can deliver applications to people all over the world faster and safer.
Web 2.0 applications, SaaS (Software as a Service) and cloud are just some of the critical components to the success of a business. Web applications are booming but the standard Internet protocols were not designed to endure this type of use. This can cause slowdowns with the multiplicity of places of connection and devices used by consumers. This is where a CDN can be very useful.
Here are 4 advantages of using CDN, Content Delivery Network:
1. Developing and managing applications worldwide
Through a CDN, distribution of enterprise applications leverages the power of a global network. This includes points of presence (PoPs) worldwide, which act as local access points to send and receive data. By leveraging existing infrastructure and acceleration technology of an application delivery network (ADN) it becomes easier for companies to develop based on their needs and their traffic.
2. Providing quality experience to end users
Nothing slows down productivity as a slow application. The distribution of business applications eliminates the problems associated with latency between enterprise servers and end users, and thus optimizing intermediate internet infrastructure and reducing data roundtrips required to process user requests. The response time is reduced, which in returns improves user experience.
3. Reduction of IT Costs
Traditional accelerating of application layer, such as WAN optimization hardware, requires significant capital investment. Content delivery network helps reduces that. Buying server spaces in global data centers is another solution to improve performance. Comparatively, a CDN requires no capital expenditure and allows using the money for operational expenses. A partnership with a CDN provider also helps to save on maintenance of equipment and technical assistance.
4. Increase Presence in New Markets
Penetrating new markets require effort and commitment, but it is also a tremendous opportunity. More than 40% of the world population has access to internet now; that’s more than 3 billion people, and this number is constantly increasing. Cloud applications are therefore more than ever necessary. Content Delivery Network provides the structure and performance required for business success in the global market. With its distributed network of servers, CDN offers the same experience to a user in China as in the United States.

Research on “Real Time Encephalography" covers the development of mathematical methods of signal processing in order to improve the effectiveness of the implementation of the biofeedback (BFB), the neurofeedback (NFB) and the brain-computer interface (BCI) paradigms, as well as other paradigms, based on the real time analysis of multi-channel biological measurements. These paradigms are real-time closed-circuit systems and generally consist of three main parts.
The first step is to measure the physiological activity of a person using various devices recording electromyographic (EMG), elecorticographic (ECoG), electro- and magnetic- encephalographic (E/MEG) signals describing the activity of muscular and nervous systems. In the context of BFB and BCI paradigms, these devices record the information from a number of sensors located on the skin (EMG), the scalp (EEG) or in the immediate area of the head (MEG). The received multichannel signal would then be amplified, digitized and sent to the computer for the further processing.
The second step is to process the information in real time selecting target signals representing various aspects of the physiological activity. Normally, the task of selecting the target signal is divided into in two phases of processing: spatial and temporal filtering. At the stage of spatial filtering, multi-channel signals are combined into one virtual channel, which has a well-defined physiological interpretation. During the temporal filtering stage, the virtual signal goes through the frequency analysis, in which the oscillatory components of physiological activity are being determined. Some additional information can be found while selecting the envelope of a narrow-band signal (which may be used to estimate the power of a particular oscillatory activity) or during the physiological state classification.
The third step of the real-time encephalography paradigm varies from application to application. In the case of BFB, the selected target signal is presented to a subject as a sensory (visual, tactile, auditory, etc.) feedback. In the case of BCI, the target signal is used to interact with a software or to control an external device. Another interesting application of the paradigm is brain stimulation practiced at the time of the physiological event.
The main research areas of the laboratory in this project is the development of methods of increasing the efficiency of real-time encephalography paradigms by improving the spatial-temporal specificity of processing of the bioelectric signals. Methods of predicting the effectiveness of the NFB therapy are also being investigated, as well as the ability to adjust ergonomic parameters of the feedback signal.

OrderPaperToday – A bill for an Act to establish a Nationwide Toll-free Emergency Number throughout the federation has scaled second reading during plenary on the floor of the Senate on Wednesday.
Sponsored by Senator Ibikunle Amosun (APC, Ogun Central), was read the first time on Wednesday, 2nd December, 2020.
In his debate, Sen. Amosun stated that the bill sought to provide for a nationwide toll-free emergency number that will aid the implementation of a national system of reporting emergencies and for other related matters.
“Emergency telephone number is typically a three-digit number that can be easily remembered and dialed quickly.
“Emergency numbers are needed in life-threatening situations. They can also be used to report emergencies of various types such as road accidents, fire, burglary, medical emergencies and so on.
“Emergency telephone lines are set up in a way that once a call is made, it must be answered by either a dedicated telephone operator, computer-aided call handling system, or an emergency service dispatcher trained to control the calls in order to provide help in an appropriate manner.
“The dispatcher may find it necessary to give urgent advice in life-threatening situations. Some have special training in telling people how to perform first aid or CPR (Cardio Pulmonary Resuscitations) which may be lifesaving.”
According to the lawmaker, the direct dial emergency number system was first deployed in United Kingdom in July 1937 using the code 999. In the United States, the first emergency call using the dedicated code ‘911’ was made in Haleyville, Alabama in 1968. India’s national emergency response number on the lines of 911 became operational in 2014.
“In many parts of the world, an emergency service can identify the telephone number that the call has been placed from. With the latest enhanced systems, such as the ‘911’ code, emergency telephone numbers are able to provide physical locations of mobile telephones, and these are often specifically mandated in a country’s enabling legislation.
“Nigeria has several helpline numbers for emergency situations. In Lagos State for example, there are several toll-free emergency numbers for Police, Ambulance, Fire Service, LASTMA, KAI, LASEMA, Women Abuse Domestic Violence helpline, Child Abuse helpline and flying Doctors (Air ambulance and medical crews) amongst others.
“The FCT, Ogun State and some other States of the Federation have different emergency numbers. The presence of multiple emergency telephone numbers in Nigeria have been identified as impediments to getting accelerated emergency response during emergency situations.
“The bill essentially seeks to establish efficient and effective emergency response system. It proposes the use of ‘112’ as the National Emergency number or any other three digit numbers as may be agreed upon during the Public Hearing, if the Bill scales through the second reading.
“A Nationwide system for reporting emergencies would dispense with the multiplicity of emergency numbers and provide a single point contact for assistance in case of any kind of emergency. Calls or text messages sent to the Emergency Number will land at the nearest public safety answering points or the control room for necessary secondary responses. Emergency number would create easy access to Nigerians especially those in remote areas, Nigerians and other residents in the country can use the toll free numbers to seek help in times of distress and emergency.
“Recent statistics shows that close to 90% of Nigerians own mobile phones, therefore a toll free emergency number will go a long way in ensuring that Nigerians in distress are just a dial away from the relevant emergency institutions. The number will provide a one stop shop for receiving distress calls from the public and dispatching same to appropriate response agencies (first responders) who will respond to the needs of the callers.
“The proposed 112 toll free national emergency line is easier to learn, remember and dial. It will save a lot of Nigerians the stress of having to memorize more than one emergency number.
“This bill clearly intervenes to facilitate emergency response system in the country by coordinating the response numbers for effective administration and management. For this to be effectively carried out, there is need for a synergy between the Nigerian Communications Commission (NCC), other relevant agencies of the Government and the Mobile Network Service Providers”, he concluded.
The President of the Senate, Ahmed Lawan referred the bill to Committee on Communication for further legislative inputs.

Harmonic was selling an open system verses the major vendors in the field who were selling proprietary systems.|
|Videotron Limited, an innovative privately owned cable system, saw the advantages to Harmonic's open solution. In a three day shoot on location in Montreal, we let Videotron tell how they decided on Harmonic and how they were going to exploit the new technology.|
|Harmonic has used the video for over a year and plans to turn it into a DVD and place it in the hands of every salesman.|

New Traffic Control System Reduces Wait Time at Traffic Lights
Construction begins Monday, August 19 on an adaptive traffic control system designed to make traffic flow more smoothly by decreasing the amount of time motorists spend at red lights. The new technology, called InSync, will be implemented at 24 signalized intersections along Chamberlayne Avenue, Brook Road, Hermitage Road and Laburnum Avenue.
InSync will change the traffic signals based on real-time vehicle demand. The technology will count the number of vehicles on both the main streets and side streets at the intersections. Then, through the use of wireless broadband radio communications, the traffic signals will “talk” with each other and relay real-time information needed to control the movement of the vehicles along the signalized corridor. A computer processor at each intersection uses the information to develop signal timings that allow main street traffic to catch multiple green signals without stopping along the corridor and, at the same time, limit and reduce the amount of time motorists spend waiting on the side street.
In addition to shortening time at red lights, the new technology will ease congestion and help drivers spend less time in traffic, which results in lower vehicle emissions and fuel consumption, which aligns with Mayor Dwight C. Jones initiatives to reduce the City’s carbon footprint.
Once the system is operational, motorists can expect a smoother commute in both directions with fewer stops at traffic signals. Motorists turning onto main streets from side streets can expect shorter delays waiting for traffic signals to turn green. The change will be most noticeable on the main streets during peak travel times and the side streets during off-peak hours.
This project was funded through a grant from the Congestion Mitigation/Air Quality (CMAQ) program. The estimated construction cost is approximately $1.4 million. The work is scheduled for completion in mid-February of 2014.
