In recent years, number of industrial, medical, safety and scientific applications, in which invisible ionizing radiation (e.g. gamma-rays, X-rays) has to be detected, have been developing rapidly. This booklet deals with the description of scintillation materials that are suitable for this purpose. Scintillation materials convert the energy of high-energy ionizing radiation into ultraviolet (UV) or visible photons, which can then be converted into an electrical signal by conventional photodetectors and further processed. Among the best known scintillation applications are computed tomography (CT), positron emission tomography (PET), LHC particle accelerator detectors in European Center for Nuclear Research (CERN), or modern monitoring unmanned drones used around Fukushima nuclear power plant in Japan.

Solar panels are not new. But with solar power storage becoming mainstream — especially since Tesla released its Powerwall last year — it is more possible than ever to completely generate your own electricity from the sun.
And if you’re Australian, solar power is already mainstream. At least a quarter of homes in Australia have solar power.
If you’re considering a solar system for your home, then keep reading to find out what options you have with the latest solar battery technology.
Why even consider an alternative energy solution
Let’s get one thing straight.
Solar power is not the perfect alternative to fossil fuels.
At least, not if you need to store it with batteries.
As I’ll discuss below, solar batteries contain materials that are non-renewable.
And depending on the battery technology, some resources are less abundant than others. Which brings into question the scalability of these technologies.
And the cost of mining these resources could potentially be as damaging as fossil fuels.
But as of right now, there is no alternative energy solution that is 100% renewable with no impact to the environment.
And the bottom line is, fossil fuels is a finite resource that we can’t count on forever.
With the world’s population exploding, and third world countries becoming industrialized, we’re using up whatever resources we have left faster and faster.
There may be enough to last our lifetimes, but it’s unlikely to last for our children and grandchildren.
So we have to be open to all alternative options.
And in the case of solar power with storage, we have some feasible options for individual homeowners.
Even better when we can this kind of alternative energy to rebuild communities when standard options have failed, as in the case of Tesla using its solar panels and batteries to bring back much needed electricity to Puerto Rico.
Battery solutions today
Just like all technology, as it becomes more mainstream, the quality increases and the cost to manufacture comes down.
And solar batteries are no different. Prices have fallen 24% even since 2016.
So it’s more possible than ever to to own a complete solar system with storage.
Types of battery storage
There are three main types of solar batteries.
The technology that has been used for decades is lead acid. It has a short lifespan but is cheaper than the other types out on the market today.
A saltwater battery is a new type of technology which doesn’t contain any toxic or flammable materials. It uses a saline solution as its electrolyte.
Aquion Energy is the first company that has developed a saltwater battery for solar use.
The advantage compared to lithium ion is that the battery capacity doesn’t fall with multiple cycles of charge and depletion.
However, the power output is lower.
By far the most popular option is lithium ion, which is the same technology used in our cell phones and laptops. These batteries are smaller and more lightweight than lead acid, with longer lifespan, but they also cost more.
The main disadvantage of lithium ion is that its capacity decreases with each charge cycle. And capacity decreases even faster with higher charge rates and higher temperature.
For example, over time, the capacity of a Tesla Powerwall decreases significantly, if its warranty is any indication. The warranty 5 years into ownership drops from 5.44 kwh to 3.8 kwh, a 30% drop.

This is the newest technology on the market. The interesting thing about zinc bromide batteries is that the energy storage capacity never declines. And you can drain it 100% and it won’t suffer any consequences. It’s also non-flammable and recyclable.
However, it doesn’t match lithium ion in life cycle, efficiency, or power output.
RedFlow Technologies in Australia is the first company to deliver a commercially-available zinc bromide solar battery.
How much in energy cost could you save?
This depends on what kind of system you implement.
If you decide to go completely off-grid, that means you’re not connected to the utility company as a backup.
So you would need enough batteries to store the excess energy that your solar panels generate during the day to be able to use it at night when your panels are generating nothing.
And you would also need to account for extra storage in the event that you have a stretch of cloudy days are you’re not producing enough excess energy to store.
Depending on how much energy you use and how much direct sunlight you get, you might need anywhere from 17-42 panels. The average home uses 900kwh of electricity per month, or almost 11,000kwh per year.
Then you would also need batteries to store the excess power. For example, you would need two Tesla’s Powerwall units (total usable capacity 27kwh) for backup.
In this scenario, you would obviously not be paying for any energy usage from a utility company.
On-grid, mostly using solar power
Another option is that you can stay connected to the utility company but you still have the solar panels and batteries to mostly or exclusively use the solar power that you generate.
The good news is, if your system is generating excess power, and your batteries are topped off, you can sell it back to the utility company.
These rates aren’t anything to write home about (probably a few cents per kwh in the Bay Area), but you can feel good about contributing energy to the utility company’s customers.
Depending on how much electricity your system produces, you could theoretically not use any energy from the grid and even make a small amount from selling the excess power.
On grid, small battery
A third option is to stay connected to the grid and only maintain a small enough battery to reduce your total energy usage from the utility company.
The solar panels would power any usage during the day and top off your battery. Then the battery would be just big enough to give you enough power during peak evening hours.
It would be reasonable to significantly reduce your utility grid consumption and cost with a bare-minimum type of solar system.
Is it worth having a solar system in a cloudy climate?
Solar panels don’t produce as much electricity in cloudy weather compared to a clear, sunny day.
So is a solar system still worth having?
The short answer: yes.
SolarCity has done studies in the cloudiest climates and have determined that total annual output can still be quite significant.
In fact, a 6-kw system can produce over 80% of a household’s annual electricity usage.
In some cases, partial clouds can generate more electricity than a sunny day because of the “edge of cloud” effect. The sun hits the edge of a cloud and intensifies the sunlight, boosting the power generation.
This is a similar effect to sunlight reflecting off snow or water.
And using solar batteries to store enough power to accommodate the cloudy days should dispel any remaining concerns.
What the future holds for battery technology
Could solar batteries go mainstream? Many technology experts say yes.
But lithium ion batteries may not be the type to scale.
Gel zinc bromide technology
In response to some of the limitations of lithium ion and existing zinc bromide technologies, Australian-based company Gelion Technologies has developed a zinc bromide battery using gel instead of a liquid based electrolyte.
Essentially, the gel moves the electron charges faster.
Which means that a solar battery with this technology can charge in minutes.
Gelion also says it beats lithium ion in efficiency, lifespan, and cost.
However, this product isn’t yet available in the market.
But what’s exciting about this is that the technology can be incorporated into building materials.
In other words, your walls and your roof are batteries storing electricity.
Zinc and Bromide also have more supply and are cheaper materials than lithium and cobalt and would be able to scale easier.
Is this a perfect replacement for fossil fuels?
No, it’s not.
While producing electricity from sunlight IS renewable, the manufacture of batteries uses resources that are not renewable.
Namely, lithium, cobalt, zinc, and bromide.
Even salt is non-renewable (at least at the rate that humans consume it), but it is one of the world’s most abundant resources.
But while it’s not perfect, solar power with batteries does give us options.
It helps us be less reliant on public utility companies that may have frequent blackouts and brownouts.
And we can each make the choices we feel are best for ourselves and for the greater community.


Gravity Assist, also known as gravitational sling shot or gravity slingshot, is a technique employed by spacecraft to gain speed, alter trajectory, and conserve fuel during interplanetary missions. By leveraging the gravitational pull of celestial bodies, such as planets or moons, spacecraft can harness the energy of these gravitational fields to enhance their missions. This article explores the mechanics of gravity assist and provides examples of its successful applications.
Mechanics of Gravity Assist
Gravity assist relies on the principle of conservation of energy and momentum. As a spacecraft approaches a massive celestial body, it enters its gravitational field, where it experiences a gravitational pull. By carefully planning the trajectory, the spacecraft can use the planet's gravity to gain or lose speed and change direction. During the flyby, the spacecraft exchanges momentum with the celestial body, thereby altering its own trajectory without the need for additional propulsion.
Speed Boost and Trajectory Alteration
When a spacecraft approaches a planet or moon for a gravity assist, it executes a close flyby to gain or lose velocity. By carefully selecting the trajectory and the direction of the flyby, the spacecraft can gain a significant speed boost, effectively "stealing" a fraction of the planet's orbital energy. This allows the spacecraft to accelerate, change direction, or reach destinations that would otherwise be challenging or resource-intensive to achieve solely through onboard propulsion.
The spacecraft gains additional velocity during the gravity assist maneuver at a specific moment known as the closest approach or periapsis. As the spacecraft approaches the planet, it moves in the same direction as the planet's orbital motion. The spacecraft exchanges momentum with the planet, effectively "borrowing" a portion of the planet's orbital energy. This exchange of momentum causes the spacecraft's velocity to increase.
However, it's important to note that the gravity assist does not involve the burning of thrusters on the spacecraft. The velocity gain is achieved purely through the exchange of momentum with the planet. The spacecraft does not expend additional propellant during the gravity assist maneuver.
After passing the periapsis and moving away from the planet, the spacecraft continues on its new trajectory with the gained velocity. As it moves farther from the planet, the gravitational influence weakens, causing the spacecraft's velocity to gradually decrease. However, the spacecraft retains a portion of the gained velocity, allowing it to continue its mission with an altered trajectory or increased speed relative to its pre-gravity assist state.
Fuel Efficiency and Mission Enhancements
Gravity assist maneuvers offer significant benefits in terms of fuel efficiency. By utilizing the gravitational forces of celestial bodies, spacecraft can conserve precious onboard fuel that would otherwise be required for propulsion. This fuel efficiency translates into extended mission durations, increased payload capacity, or the ability to reach distant destinations within feasible timeframes.
Use of this principle in Chandrayaan Missions
The Lunar Vehicle Module 3 (LVM3) used in the mission is not as powerful as the NASA's Saturn 5 rockets, which allows for a more cost-effective approach. Instead of following a direct path, the spacecraft takes an elliptical orbit around the earth, utilizing gravitational forces to gain speed and momentum. This strategic trajectory enables Chandrayaan-3 to conserve fuel while still reaching its lunar destination. That is also the reason why Chandrayaan taking around 40 days to reach Moon.
Other examples where Gravity Assist was used.
Voyager Missions: The Voyager 1 and Voyager 2 spacecraft executed multiple gravity assist maneuvers to explore the outer planets of our solar system. The gravity assists from Jupiter and Saturn provided velocity boosts and altered their trajectories, enabling them to continue their interstellar missions.
Cassini-Huygens: The Cassini spacecraft utilized gravity assists from Venus, Earth, and Jupiter to reach Saturn and its moons. These maneuvers saved fuel, reduced mission time, and facilitated extended exploration of Saturn's system, including the successful landing of the Huygens probe on Titan.
New Horizons: The New Horizons mission to Pluto employed a gravity assist from Jupiter, which accelerated the spacecraft, reduced the travel time, and enhanced its scientific observations during the Pluto flyby.
Gravity assist is a powerful technique that allows spacecraft to leverage the gravitational fields of celestial bodies for speed boosts, trajectory alterations, and fuel conservation. This ingenious maneuvering method has been successfully utilized in numerous interplanetary missions, enabling extended explorations, precise flybys, and access to distant destinations. As space exploration continues to evolve, gravity assist remains an invaluable tool for unlocking the mysteries of our solar system and beyond.

CIRCUMAURAL headphones (sometimes referred to as "Around Ear" headphones) encircle the ear creating a seal thereby effectively reducing ambient noise from getting to the ear. This is known as passive noise reduction.
This type of headphone is most effective in a high noise environment where it's necessary to eliminate as much of the environmental noise as possible for effective communication.
While the overall transmission range for wireless headphones is mostly determined by the wireless technology being utilized by the individual wireless headphone product there are multiple external factors (like obstacles, audio signal strength, wireless signal congestion, etc) that can effect the wireless signal transmission range of wireless headphones.
Obstacles are one of the main factors that can effect the transmission range of the wireless signal. While the wireless signal (with the exception of infrared signals) can pass through obstacles (like walls) ultimately range will be affected (likely reduced) by passing through these obstacles and the more dense the obstacle the greater the effect will be on the signal. For example a signal passing through a glass window won't be affected very much whereas a signal passing through a concrete wall will be effected much more greatly. Having a clear line of sight does provide the best transmission range.
The audio signal being output by your audio source to the transmitter of the headphones is another key factor in transmission range. A weaker audio signal going into the transmitter means the transmitter has a weaker signal to work with which can in turn reduce the transmission strength which ultimately affects range. Ensure that your audio source is outputting the best possible signal for the transmitter to use.
A2DP (Advanced Audio Distribution Profile) is a Bluetooth profile that defines how multimedia audio can be streamed from one device to another over a Bluetooth connection.
Most Sennheiser Bluetooth headphones utilize the A2DP profile as it allows for the best audio transmission over Bluetooth hence providing the best audio in the headphones.
NOTE: If the device you are connecting to does not support A2DP there may be connectivity issues between the Sennheiser unit and the device. In situations like this most Bluetooth Chipset manufacturers offer firmware updates to the Bluetooth chip to allow the A2DP profile to be utilized.
The Apt-X refers to a built in codec that takes the available Bluetooth audio and enhances it so you have a superior sound. In order for the Apt-X codec to be utilized both the headphones and the device that they are connected to need to have the Apt-X codec built in.
If the codec is not available in the device you are connected to the headphones will still work however you will not have the benefit of the Apt-X codec. If a device does not have the Apt-X codec built in you can purchase a device called a Bluetooth dongle with the Apt-X codec that will connect to your device and allow you to utilize the codec.
NOTE: Apt-X will not affect Bluetooth connectivity with a device.
Our Wireless Headphone Systems can be connected into virtually any audio device and it is just a matter of identifying the appropriate audio output port and then having the appropriate connecting plug or component.
The type of connector you have available will depend on the Sennheiser Wireless Headphone System that you choose. The type of audio output that you will have available to connect into will depend on the audio device you are connecting to.
Typical audio output ports include:
- 3.5mm headphone port
- red and white RCA audio output ports
- digital audio output (either optical or coaxial)
NOTE: In some instances an adapter or extra component will be needed to make the appropriate connection.
For example to change a 3.5mm headphone plug to an RCA connection you would use a female 3.5mm to male RCA adapter.
For example to change an analog connection (3.5mm headphone plug or red and white RCA plugs) to a digital connection (ie: optical) you would use a digital to analog decoder (like the OREI DA 34).
The wireless headphones that utilize a digital transmission signal operate in the unlicensed 2.4 Ghz range as do many other wireless devices (like WiFi routers, wireless printers, etc) and the headphones have a specific frequency range on which they can operate. The headphones scan the local wireless signal environment and then automatically select an unused frequency within their designated range. The headphones are designed to work in conjunction with other wireless devices without the different devices interfering with each other.
Typically the bandwidth of the WiFi router is greater than that of the headphones and it actually encompasses the bandwidth that the headphones want to use. Most of the time the two signals are away from each other and there is no issue. Occasionally if the WiFi router has established it's signal in the bandwidth that the headphones want to use then the two signals butt up against each other this can cause issues. Sometimes it is possible to change the WiFi router frequency manually by using a switch on the router itself.
In situations where the WiFi router cannot be changed manually the simple solution is to turn off the headphones and the WiFi router. Start the headphones and let them run for 15 minutes to establish their signal and then turn on the WiFi router. The WiFi router will "see" the signal of the headphones and establish it's own signal in a different part of the bandwidth and the two devices will work without interfering with each other. NOTE: Once this process has been done the signals are established and will remain established even with a device is turned off.
If the above solution does not resolve the issue it may be a situation where the wireless environment is too crowded and the multiple wireless signals keep butting up against each other and causing issues. To resolve this some wireless signals would need to be removed from the environment (ie: turned off). For example if a wireless printer was turned on it is creating wireless signal that would be part of the wireless signal congestion. If the printer is not used all the time then it could be turned off to reduce the congestion and allow the other wireless devices (like the headphones) to work.
Near-field communication (NFC) is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within 4 cm (1.6 in) of each other.
NFC devices are used in contactless payment systems, similar to those used in credit cards and electronic ticket smartcards and allow mobile payment to replace/supplement these systems. NFC-enabled devices can act as electronic identity documents and keycards. NFC offers a low-speed connection with simple setup that can be used to bootstrap more capable wireless connections.

If you are a fan of Xiaomi products, you will be looking forward to a couple of launches that are set to happen in December. In China, Xiaomi will be unveiling the successor to the Redmi K20 series whereas in India, the Mi Note 10 is expected to make a debut. However, Xiaomi could also bring a couple of new products to both China and India that may be reserved for the latter half of December. Since there are a couple of products, we accumulate all the Xiaomi products expected to debut next month as well as the ones that are confirmed for launch.
Xiaomi Redmi launches in December
Redmi K30 (in China)
The Redmi K30 has been the hype on social media for a while and Xiaomi has given a date for the official launch which is on December 10. The Redmi K30 is said to be the successor to the Redmi K20 from earlier this year and it will bring some major upgrades over the old model - thanks to a bunch of leaks on Weibo.
The major upgrade comes in the form of a 120Hz refresh rate display with a dual hole-punch cutout. The display will use an LCD screen with thin bezels all around and curved corners. Inside, there will be a Snapdragon 730G chipset that's known to be paired with at least 6GB RAM and 64GB storage. It will run on MIUI 11 as usual. A 4500mAh battery with support for 27W fast charging is also said to present.
Shutterbugs could be contented with a quad-camera setup at the back, comprising of a 64-megapixel main camera along with a 13-megapixel wide-angle camera, an 8-megapixel telephoto camera and a 2-megapixel depth camera. A 32-megapixel selfie camera will also be present on the front. And, the new model could still start from approximately Rs 20,000.
Mi Note 10 (in India)
The Mi Note 10 launched last month in China but Xiaomi is now set to bring it to India. This will be the first Mi Note series phone in India and it could straightaway compete with the likes of OnePlus 7T, Asus 6Z and even the Redmi K20 Pro. What's so special about this one? The cameras, of course!
The Mi Note 10 has a headlining Penta camera setup that features a 108-megapixel main camera paired along with a 12-megapixel telephoto camera with 2x optical zoom, another 5-megapixel telephoto camera with 5x optical zoom and a 2-megapixel macro camera. Huff! This is like a Swiss army knife for camera lovers. And that's not all, there's a 32-megapixel selfie camera for taking high-res photos.
The Mi Note 10 also focuses on being premium with a Gorilla Glass 5 protected front and rear glass body with curved edges. The display uses a 6.4-inch Full HD AMOLED panel with narrow bezels. A Snapdragon 730G chipset paired with 6GB RAM and 128GB storage controlled by MIUI 11 takes care of the performance wing. And to keep the phone alive, there's a 5260mAh battery with support for 30W fast charging system.


XGSLab (Over and Under Ground System Laboratory) is one of the most powerful software packages for grounding system analysis, electromagnetic fields, interference and lightning analysis and the only software on the market that takes into account both EN and IEEE Standards.
XGSLab includes the modules:
GSA (GROUNDING SYSTEM ANALYSIS) for regular application (applicable in most practical cases).
GSA_FD (GROUNDING SYSTEM ANALYSIS in the FREQUENCY DOMAIN) for electromagnetic fields and interference evaluations for overhead and underground systems and for fault current distribution calculations.
XGSA_FD (OVER AND UNDER GROUND SYSTEM ANALYSIS in the FREQUENCY DOMAIN) for electromagnetic fields and interference evaluations for overhead and underground systems and for lightning effects and fault current distribution calculations.
XGSA_TD (OVER AND UNDERGROUND SYSTEM ANALYSIS in the TIME DOMAIN) for general applications with overhead and underground systems.
All modules are integrated in an “all in one” package and based on a hybrid calculation method (or “PEEC” method) which considers transmission line, circuit and electromagnetic theory combined into a single calculation model.
Hybrid methods join the strong points of the other methods and are well suited for engineering purposes because they allow the analysis of complex scenarios including external parameters such as voltages, currents and impedances. For these reasons, XGSLab can be considered a real laboratory.

Facial recognition technologies are among the most trusted and efficient access control tools available to smart cities.
Computer vision is when AI has eyes and automates human sight. It has countless applications in many fields, including construction, security, agriculture, and many more.
Facial recognition technology is making many areas of life more convenient. People can now verify their identity without so much as a password or fingerprint. These technologies allow masses to access buildings without a key or breeze through airport security. But like any other privacy technology, fraudsters are targeting facial recognition via spoofing.
Modern facial recognition applications go far beyond accessing an iPhone or smart home. Today, facial recognition is proliferating into areas like air travel, retail, hotels and banking. That's because facial recognition can make customers' lives easier and businesses more efficient.
We've come a long way from ringing the doorbell or even needing keys to enter our homes, offices and buildings. Technology has given us smartphone apps, finger scanners and key cards. And now, facial recognition is making access even more convenient and secure.


The Japan Society for the Promotion of Science
The 191st Commitee on Innovative Interface Bonding Technology
Room-temperature bonding is an original technology of Japan. Over the past 10 years, Japan has been the international hub for R&D in this field. 3D device integration and MEMS packaging based on room-temperature hetero-wafer bonding are attracting international attention. Components of this technology are already being applied to mass-production. The research has revealed a large number of potential applications: Not limited to semiconductors and metals, this bonding technology can also be extend to glass, organic fiber, silicon photonics, and optical microsystems as well as next-generation displays, solar cells and fuel cells. It even shows potential application to flexible electronics. As international interest heightens in this technology, other countries have begun eying similar bonding techniques. The US and Europe are showing brisk research activity in this field of room-temperature bonding, pioneered by Japan. If Japan should waver in its thrust, it could cause a thinning of its researcher layer in this field along with a weakening of its networks.
Against this backdrop, the Committee on Innovative Interface Bonding Technology was established to go beyond advancing room-temperature bonding as a mere bonding technique. Rather, its mission is to advance the development of a more substantive material interface generation technology and, by utilizing the latest advances in interface science and analytical technology, to formulate a new bonding and interface theory. For that purpose the Committee provides a platform that brings together researchers from the academic world who are advancing basic research toward introducing new bonding processes that increase bonding reliability and researchers in the industrial world who are working to develop technologies to meet new manufacturing needs.
The Committee surveys the latest R&D trends in both Japan and abroad so as to navigate Japan’s direction in advancing interface generation technologies, especially room-temperature bonding and surface-activated bonding. Towards this end, it carries out overseas surveys, periodically holds closed meetings, and convenes hearing to which it invites overseas researchers. In addition, the Committee works to identify basic bonding and interface problems and seeks ways to solve them from the three perspectives listed below. In doing so, its ultimate objective is to systematize bonded interface generation technologies and propose new processes for achieving them.
By way of these activities, the Committee seeks to sustain Japan’s position as the flagship within the international R&D flotilla on room-temperature bonding technology, while contributing to Japan’s industrial development by producing state-of-the-art manufacturing technologies.

OnePlus Technology was established in 2013, and OPP is the majority shareholder. The company, since its establishment, ventured to smartphones, and they have been producing high-quality smartphones. The OnePlus 9 Pro has been a hotly anticipated smartphone for some reasons.
Perhaps the top-most anticipatory aspect of the phone is the result of the Hasselblad-OnePlus collaboration. Other things include curiosity about how the new Qualcomm Snapdragon 888 performs and, in general, what new things does OnePlus 9 Pro brings to the table.
ONEPLUS 9 PRO SPECIFICATIONS AND FEATURES
The OnePlus 9 Pro maintains the company's legacy of featuring high-quality hardware. ONEPLUS 9 PRO is not an exception because you'll get the Qualcomm Snapdragon 888 SoC, which is a unique chip in it. There is also the inclusion of Four Kryo 680 cores based on Cortex A55 cores, three Kryo 680 cores based on Cortex A78, and one Kryo 680 ARM's big boy X1 core.
The X1 core was first revealed last year, and ARM claimed at the time that it would most likely be reserved for higher-end devices like laptops. We've arrived at a point where the X1 is a component of a smartphone SoC. In addition, OnePlus has found out how to use the storage as virtual RAM. This is referred to as a Pagefile on the PC side of things.
Other notable features of the phone include a QHD+ display with a 120Hz refresh rate, which you will undoubtedly enjoy. A 4500mAh battery with 65W fast charging is also included.

Last week I joined the company of about a million others and became the proud owner of a Raspberry Pi. I got it just for fun; write some software and maybe make use of the GPIO ports.
I already knew I wanted to do something Eclipse related with this quite capable device, so why not run Eclipse Orion (Tools for the web, on the web) on it? During my research I discovered that someone already did that. Ken Walker of IBM Canada/Orion Project even demonstrated such a set-up as a teaser for a talk at last year´s EclipseCon Europe. Now he used the Node.js port of Orion – I had in mind to use the full package. Note that Ken also has a talk on the subject at this year’s EclipseCon in Boston.
Support for software floating point is required for Java; so we have to pick a Linux distribution that provides this. The Soft-float Debian “wheezy” is a good choice. Note that I had trouble getting the image downloaded from the torrent to work. The direct download of the zip file was OK. Compare the SHA1 hashes to make sure.
torkild@Isis:~$ openssl sha1 Downloads/2012-08-08-wheezy-armel.zip
Now we need to write the disk image to the SD card. First you must figure out where the card is mounted. On my MBP this is /dev/disk2. We must first unmount it. Note that these instructions are for OS X, if you’re on Linux there are some differences. If you’re on Windows you’re on your own. Sorry about that.
torkild@Isis:~$ diskutil unmountDisk /dev/disk2
We can now write the image. Execute the command below and be prepared to wait for quite a while. All depending on the performance of your SD-card.
torkild@Isis:~$ sudo dd bs=1m if=Downloads/2012-08-08-wheezy-armel.img of=/dev/rdisk2
When done, insert the SD-card, connect the Ethernet cable and USB power. The green LED should start blinking and after a while all LEDs should be on. This means you should be able to log into a shell on the device. First you need to figure out it’s IP-address. You can do this from the terminal if you have a screen and keyboard hooked up. I used the nifty iNet iOS application for that and found 192.168.1.105.
torkild@Isis:~$ ssh -l pi 192.168.1.105
Enter the default password (“raspberry”) and you should be greeted with a welcome message. The shell prompt will also change, indicating that you’re now logged in as pi on raspberrypi. We should start with some initial setting up.
Now, would it not be nice if we could access the Raspberry Pi without having to remember it’s IP-address (and without having to set up a DNS server)? We can do this by making use of multicast DNS (mDNS).
pi@raspberrypi ~ $ sudo apt-get install avahi-daemon
Now the Raspberry Pi can be accessed using it’s name. Try it:
torkild@Isis:~/git$ ping raspberrypi.local
PING raspberrypi.local (192.168.1.105): 56 data bytes
64 bytes from 192.168.1.105: icmp_seq=0 ttl=64 time=52.174 ms
64 bytes from 192.168.1.105: icmp_seq=1 ttl=64 time=1.380 ms
Upgrade software and kernel
Things move fast in the open source world so the software that comes with the Raspberry Pi is unlikely to be up to date. Hence we should upgrade to the latest version of both the software and the kernel.
pi@raspberrypi ~ $ sudo apt-get update
pi@raspberrypi ~ $ sudo apt-get upgrade
Expand root partition
In order to make more room we can make the root partition expand to fill the entire SD-card, start
expand_rootfs then exit and reboot.
pi@raspberrypi ~ $ sudo shutdown -r now
Wait a bit and log in again. The root partition should be much larger than the 1.8GB default.
pi@raspberrypi ~ $ df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 15G 1.4G 13G 10% /
If you got your Raspberry Pi recently you probably have one with 512MB RAM, but all of that memory is not necessarily available. Check the memory chip to see which type you have and run
free -h to see if the memory is there. My Raspberry Pi is a 512MB variant, but reported only 231MB available. In order to fix this we need to update the firmware. Thankfully we can make use of a nice script to do this.
pi@raspberrypi ~ $ sudo -i
root@raspberrypi:~# rm -rf /boot/*.elf /boot/*.bin /boot/*.img
root@raspberrypi:~# apt-get install git
root@raspberrypi:~# wget http://goo.gl/1BOfJ -O /usr/bin/rpi-update && sudo chmod +x /usr/bin/rpi-update
As we’re going to use the Raspberry Pi without a graphical user interface it may be a good idea to limit the GPU memory to 16MB, this will allow applications to use more. Edit
/boot/config.txt and add
gpu_mem=16 to the bottom of the file. Now we need to restart again. After the device has booted we should see a lot more memory.
pi@raspberrypi ~ $ free -h
total used free shared buffers cached
Mem: 485M 74M 411M 0B 10M 31M
-/+ buffers/cache: 32M 453M
Swap: 99M 0B 99M
At this point we’re ready to start installing the additional stuff. The Oracle download pages have been cleverly designed so that they are pretty impossible to use with a command line client. Hence you’ll have to pick the archive using your favourite web browser and transfer it to your Raspberry using SSH. Download the Java SE Embedded 7 , EABI, VFP, SoftFB ABI, Little Endian version and transfer it.
torkild@Isis:~$ scp Downloads/ejre-7u10-fcs-b18-linux-arm-vfp-client_headless-28_nov_2012.tar.gz email@example.com:~/
You should know how to log into the Raspberry Pi by now. Do that again (unless you’ve cleverly kept the terminal window open) and execute the following:
pi@raspberrypi ~ $ tar -xvzf ejre-7u10-fcs-b18-linux-arm-vfp-client_headless-28_nov_2012.tar.gz
pi@raspberrypi ~ $ sudo mv ejre1.7.0_10 /usr/local/
pi@raspberrypi ~ $ sudo ln -s /usr/local/ejre1.7.0_10/bin/java /usr/local/bin/
pi@raspberrypi ~ $ sudo ln -s /usr/local/ejre1.7.0_10/bin/keytool /usr/local/bin/
pi@raspberrypi ~ $ java -version
The last command should reveal something like this:
java version "1.7.0_10"
Java(TM) SE Embedded Runtime Environment (build 1.7.0_10-b18, headless)
Java HotSpot(TM) Embedded Client VM (build 23.6-b04, mixed mode)
Installing Eclipse Orion
Eclipse Orion can be found at the projects website. I picked the 1.0 release for 32-bit Linux and downloaded it to my workstation. Use scp again to copy it to your home folder on the Raspberry Pi.
Eclipse Orion can launch stand-alone websites, which is quite useful for testing your work. However we need to use virtiual host names for these sites. This is done by setting the
orion.site.virtualHosts property in the server configuration file. Create a file named
orion.confand add the following:
All sites will now be created on the form
.raspberrypi.local. We’re going to start the “Hello World” example project so we’ll need a CNAME alias for this:
pi@raspberrypi ~ $ sudo apt-get install python-avahi
pi@raspberrypi ~ $ sudo wget https://gist.github.com/raw/4645066/64b8ad371b0cad5784e162b8382de0d4786317e6/avahi-alias.py -O /usr/local/bin/avahi-alias.py && sudo chmod a+x /usr/local/bin/avahi-alias.py
pi@raspberrypi ~ $ avahi-alias.py hello.raspberrypi.local &
Now we’re ready to start Eclipse Orion
pi@raspberrypi ~ $ unzip eclipse-orion-1.0-linux.gtk.x86.zip
pi@raspberrypi ~ $ java -jar eclipse/plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
It will take some time to start. When everything looks good, open your web browser and enter the address to the running Eclipse Orion instance. It’s running on port 8080 (http://raspberrypi.local:8080/). You should be greeted by a welcome page. Create an account and log in.
Click Sample HTML5 Site and leave the defaults as they are. Simply click Submit in the dialog that pops up. Now go to Sites and create a new site. Name this one “hello” and add the “Hello World” project to it. You can now start the site and view the example project using http://hello.raspberrypi.local:8080/index.html.
That was fun! Now it’s time to read getting started with Orion…

Samsung Galaxy Note 8. The big-screen phone will be more rectangular than the current Samsung Galaxy S8, but it will have the same edge-to-edge display and come in a choice of either black or gold.
The Note 8 screen is said to be 6.3-inches across but, thanks to the lack of bezels the handset itself is around the same size as the S8.
Note 8 will be the first Samsung phone with a dual-lens camera on board. Plenty of other phones, like the iPhone 7 Plus and OnePlus 5, have included two lenses for better pictures.
Note 8 will also come with an S Pen stylus


Our broadband service is delivered by satellite. That means that if you can see the sky from where you live, we can deliver fast broadband there already.
We don’t need fibre, we don’t need copper wires, we don’t even need mobile phone masts. Our broadband already covers the whole of the Ireland with fast reliable broadband now.
Getting satellite broadband is now great value and simple. A small (74cm) dish is installed outside and a single cable connects to an indoor modem – that’s it – all over in 1-2 hours. Where we provide hardware as a part of our monthly service charge, it means that we will always be responsible for it and either repair it or replace it free of charge if it breaks-down.
Getting it installed
We offer all of our customers a superfast 20Mbps download speed with a data package to suit their needs. Because satellite uses completely different technology to Eircom and their old network, it doesn't suffer from problems like being too far from an exchange, an ageing network or too many people trying to use the same line.
The list of technology jargon and acronyms seems to get longer and longer everyday, here's a few common broadband terms and words you might come across. Hope this helps.
Mobile phone technology that includes services and applications with faster access to the web.
Asymmetric Digital Subscriber Line - the technology that allows you to receive broadband using existing telephone networks. It works like a fast telephone line that is always connected to the internet.
This is the amount of data that can be transferred over a connection usually expressed in bits/bytes per second (bps). This is a single unit of data — and in broadband terms this means the unit of transmitted data. A kilobit (Kb) is 1,000 bits. A megabit (Mb) is 1,000,000 bits.
Broadband is a faster version of the internet that works at higher speeds because of an increased bandwidth. The most commonly used form is ADSL (Asymmetrical Digital Subscriber Line) which is an upgraded home telephone line. Broadband can also be obtained through fibre-optic cable, mobile or the new generation of fast, reliable Ka satellites.
Much like cable television and telephone services, broadband is carried through a fibre optic cable buried under the ground.
An online area, or part of a website, where two or more people can ´talk´ in real time by typing messages.
A general term for videos, text, pictures or sound stored on, processed, sent or received by your computer.
This is when your computer calls your Internet Service Provider (ISP) as you connect to the internet — this can normally be heard with a dialling tone. This means you have to establish a new connection each time rather than staying online as with broadband.
Moving files from the internet on to your PC.
This is data that goes from the internet to your computer — so for example emails, downloading from the internet, etc.
Digital Subscriber Line - this technology transfers data over a phone line without interference.
This is a network standard for data transmission, most commonly used on local area networks (LANs) such as in the workplace. New systems are now capable of running at 1,000Mbps.
The service area that your connection is associated with. For example if you are unable to receive broadband where you live it is because you are not within range of a broadband exchange.
File transfer protocol — a process of obtaining and uploading files to and from the internet.
Standing for Global Positioning System. This allows the user to know exactly where they are on earth and is now used within mobile-broadband technology.
This enables information to be routed from one network to another. The information is sent in packets and then reassembled into information when it reaches its destination.
A service that allows you to ´chat´ with another internet user in real time by typing.
An individual number attributed to every computer on the internet for identification purposes.
Internet Service Provider - the company that supplies your connection.
Is the specific frequency spectrum used to provide next generation Ka technology satellite broadband services.
Is the name of the Skylogic satellite that provides the next generation Tooway next generation Ka technology satellite broadband services
is the telephone line in a home — not a mobile, but a routed line.
The time taken for a signal to pass from your computer to the satellite. Most commonly stated as around 0.7 seconds for satellite.
Local Loop Unbundling - when a provider rents space from the exchange and then sells its own services on the line.
Megabits per second. This measures how quickly data can be transmitted.
The device that allows your PC to connect to the internet via your telephone line — previously they had to be plugged in, but now they are inbuilt within computers.
This means you only pay for your actual usage — that is, downloads and uploads, looking at websites, emails, etc. You pay based on the time you spend online.
When a message is sent to another computer and the command waits for a response. This is a method often used to check if a network is reachable.
A command sent from one computer/network to another.
With a router you can set up your own home network because it will buffer and forward data. It connects the Internet Service Provider´s network together with the LAN at home through a single broadband domain. So instead of paying for a connection for each PC, the router allows you to put your home network on the same connection.
An alternative to ADSL that uses a satellite connection to provide a permanent connection to the internet.
Symmetric Digital Subscriber Line - allows more data to be sent over existing copper telephone lines at rates up to 3Mbps.
The rate at which you can receive downloads. For broadband, the connection is normally at least 256kbps and can be as much as 24Mbps. In the UK, all broadband speeds, download and upload are maximum possible speeds in accordance with Ofcom guidelines.
Allows the user to watch/listen to a download as the download commences in the background. This is most common with live streaming, such as with commentary from sports events, etc.
This is the brand name for a range of consumer and business satellite broadband services provided via the KaSat satellite.
Transferring files from your computer to the internet.
A virtual local area network. This is a network of computers that behaves as though they are connected to the same wire even though they might actually be on different sections of the LAN.
Video on Demand - a technology or service that allows a video feed to be called on near instantaneously for viewing, usually for a fee.
Voice Over Internet Protocol — allowing you to make telephone calls using the internet. These can be free for example using Skype or they can be a complete fixed line replacement service where you connect your existing telephone system/wiring into a special router which allows you to .
This is when a broadband connection provided without wires such as when using a laptop or through a mobile phone to connect to a wireless signal. Wireless networks are most commonly set-up by adding a wireless router which plugs into the Broadband Modem and uses radio waves to link users.

This week I had the pleasure of witnessing the first testing of an autonomous vehicle (AV) on a public street in Canada.
I’m proud to say that test was done right here in our city and that this is just the first of many tests to come.
It was really something special to see the BlackBerry QNX concept car driving on a public street, even stopping at a traffic light at a pedestrian crossing.
All this was made possible through the installation of special technology in the traffic lights and re-painted lines in the area.
Until Thursday, the testing of autonomous vehicles had only been done in closed, segregated areas.
The City of Ottawa is working hard to become a Centre of Excellence for Autonomous Vehicles, a highly competitive designation that will allow further advancement of driverless car testing.
The City and BlackBerry QNX are working with groups like Invest Ottawa, the Kanata North Business Association and researchers at Algonquin, Carleton and uOttawa to reach this goal.
Together, we will be able to bring the newest AV technologies, products, services and applications developed right her in Ottawa to the global market.
In the next phase of the project, Nokia will be adding LTE and 5G to the route.
- There are over 70 companies in Ottawa’s autonomous vehicle ecosystem, led by BlackBerry QNX, that are directly contributing their expertise, technology and intelligence to connected cars and autonomous vehicles.
- The test route is made possible by many partners working together:
- BlackBerry QNX, a leading developer of mission-critical software that forms the foundation for connected and autonomous vehicles, will use the test route to further advance its software and technology development in this field. BlackBerry QNX’s operating system also powers the traffic management system used by the City’s Traffic Services.
- NovAtel’s GNSS GPS base station, installed on BlackBerry QNX’s building, and Codha’s DSRC technology, installed in the City traffic lights, can communicate directly with authorized AVs, and enable them to take appropriate action.
- In-kind contributions and donations of AV technology and systems from other leading industry partners including NovAtel and Codha Wireless.
- Critical funding and support from the City of Ottawa, Invest Ottawa, the lead economic development agency for the National Capital Region, and the Kanata North Business Association, which is home to Canada’s largest technology park.
- Ottawa is home to BlackBerry QNX’s Autonomous Vehicle Innovation Centre
- The BlackBerry QNX Autonomous Vehicle Innovation Centre (AVIC) was created to advance technology innovation for connected and autonomous vehicles, independently as well as in collaboration with private and public sector organizations and research institutes.
- Building on the company’s 20 years of experience and leadership in the automotive industry, the centre will germinate new ideas and transform innovative concepts into reality through advanced engineering projects and demonstration vehicles tested on real roads.
- Carleton Research has recently secured funding from the Canadian Safety and Security Program (CSSP). As part of the program, which is led by Defense Research and Development Canada’s Centre for Security Science and in partnership with Public Safety Canada, Carleton Research will be given $974,000 over three years for research on securing new connected and autonomous vehicles (CAVs).
- To help aid the University’s research, BlackBerry QNX has signed a charter with Carleton University to provide technical expertise in the area of automotive software development.


When Dell launched its updated XPS 13 notebook with an Infinity Edge display that squeezes a 13 inch IPS panel into essentially a 12-inch frame, it was met with universal praise for its unique mechanical design advantages and premium build quality. In fact, it was so well-received that many of you almost immediately started asking if Dell would follow-up with the same sort of revamp for their 15-inch XPS 15 line as well. Dell apparently already had the same idea in mind and clearly the new XPS 15, with its 15-inch Infinity Edge display, was already in the engineering pipeline. Like the XPS 13, the XPS 15’s material choices, design and build quality are premium, through and through, from its carbon fiber composite palm rest area to its machined aluminum lid and base, and edge-to-edge Corning Gorilla Glass NBT that covers its near bezel-less display… The configuration we’re looking at here is one of Dell’s best setups with a 4K IPS display, a 6th gen Intel Core i7-6700HQ Skylake quad-core processor at 2.6GHz with turbo boost to 3.5GHz, 16GB of DDR4 RAM at 2133MHz, NVIDIA’s GeForce GTX 960M 2 GB mobile graphics engine and a 512GB NVMe PCI Express Solid State Drive. At $2229 MSRP we’ve certainly got a stacked and jacked configuration to show you here today. MacBook Pro killer? Maybe, but the Dell XPS 15 looks to be much more than something so tediously defined by cliche’. Here’s my full review on Dell’s new beautiful beast.
If you’re a PC gamer or into enthusiast computing, how would you describe your ideal monitor? For many, it might go something like a 32 – 34-inch IPS panel with a high refresh rate of 100Hz plus, 4K resolution, along with NVIDIA G-SYNC or AMD FreeSync technology. And with displays this big, adding a slight curve might be high on your wish list as well. The good news is, with the recent advancements in display technologies, that “holy grail” set of specifications is beginning to take shape, as display manufacturers like Acer, ASUS, Samsung, Dell and others begin to build all this great new tech into bigger and better high-end displays.
In fact, the new Acer Predator X34 series captures three out of four of those “ideal” spec check box items, maybe hitting all of them, depending on your perspective. Acer offers two variants of curved 34-inch IPS panels with adaptive refresh technology, a FreeSync version known as the XR341CK and a G-SYNC-enabled version called the Predator X34 that we’ll be digging into here. This panel also has a 100Hz overclock setting, a fast 4ms pixel response time and 100% sRGB color gamut capability for gaming geek nirvana as well as productivity and content creation fidelity. The native resolution for the Predator X34 is 3440X1440 in a 21:9 aspect ratio.
Here’s my full review…
The Dell Alienware team has been relatively quiet for the past 18 – 24 months or so with respect to their X51 small form factor gaming rigs, but Intel’s recent Skylake processor launch and NVIDIA’s further optimization in the Maxwell GPU architecture have given the company a frenzied salvo of artillery to work with for their tiny but mighty gaming PC product line. To boot, the past few months have brought forth new innovation at the platform chipset level, as well as within the storage space. And so it was fitting that almost from top to bottom, the Alienware X51 R3 was given a complete overhaul of the lastest technologies, all of which play very well with the tighter power budgets and thermal constraints of this class of machine…

I was recently sent a Raspberry Pi 4B computer, disassembled, with little introduction or fanfare. I have heard much about the miniature hobby computer over the past decade, but hadn’t actually used one or seen one up close until now. I put it together, and observed that it didn’t POST on its own. Being a tiny motherboard, it has no BIOS at all, and is completely dependent on the installed operating system for hardware detection and testing. I downloaded and installed a Debian image made for Raspberry Pi using their imager you could download from their website.
It boasts a quad-core ARM Processor (Revision 3). It is not your average Intel processor. All of the largest chips on the motherboard each take up no more than 1 square cm, and the heat sinks are so small that they attach like little aluminum decals to their processors. It comes with 4GB RAM installed, and a place for a Micro-SD for the operating system and limited storage. It can support up to two 4K HD monitors at 60 frames per second, each connected with micro-HDMI connectors. It has connectors for legacy Type-A USB2 and USB3 devices. I am using the two USB2 connectors for the mouse and keyboard; and the other two for “anything else”. There is a third Type-C USB3.1 connector which is used for power. The power switch itself is on the same cable as for the power supply. You can also hook up a standard Ethernet cable for connecting to a network. If you don’t have ethernet, the Pi boasts a WiFi receiver. The motherboard goes inside a plastic system box about the size of a small pack of cigarettes.
On the motherboard are pinouts which resemble the ones used for the old parallel ATA connectors from decades ago. After learning how to send power to which pin through a comnputer program, the possibilities of operating small electrical devices (lights, speakers, an arduino device, what else …?) expand greatly.
The installation had a few hitches, since it appears I cracked the first two micro SD cards either on the supplied USB adaptor, or on the micro-SD mount provided underneath the motherboard. I went and purchased a third, a 32GB Sandisk Ultra (I could have gone as low as 4GB, but this was the smallest sold by Staples). I installed the OS using their installer again, and this one booted. Since I was at home, I didn’t have access to my supplied monitor, keyboard and mouse, so I just reconnected existing devices at home, and was rewarded by a rather nice X-Windows display.
The Pi is bluetooth-enabled, but I hadn’t tried it yet. I did plug in a wireless adapter for a Logitech keyboard/mousepad combo (the K400 Plus), and it worked instantly.
Now, since I was given this computer as a teaching tool for students, I made the default account password-protected, and created a new account named “student” with fewer priveleges: they can’t install or remove software, and are not part of the “games” group. The first restriction appears effective when I tested it, but the latter exclusion from the “games” group still meant they were able to play some games, for example those that originate from the python graphics libraries. My students, like teenagers everywhere, have at least a mild addiction to computer games, so I decided to remove them as a possible distraction. Since all students will use a single account, they will need their own USB thumb drive, since there won’t be many other ways to save files edited on the Raspberry Pi. However, since it has WiFi, there is always G-Drive or OneDrive.

Monthly Meet & Eat: Quantum Computing
November 12, 2019 @ 6:00 pm - 8:30 pmFree
Eat Pizza and learn about Quantum Computing using Trapped Ions:
Please join the Western Washington ASME for a night of networking and learning as we hear from our guest speaker Dr. Ryan Bowler.
Quantum computers, or more accurately, quantum information processors, are predicted to enable a significant speedup in solving certain classes of problems compared to their classical counterparts. The elements that make up a quantum information processor include quantum bits, or “qubits,” with long lifetimes, universal quantum logic gates, information transport, and state initialization. This talk will focus on a specific implementation; the use of an atomic ion trap, wherein information transport is achieved through the movement of qubit ions across distinct trap zones. While experiment timescales had previously been dominated by ion transport and re-initialization of motional states, modern progress achieves transport and separation of qubit ions on timescales comparable to quantum logic gates. The developed techniques for ion transport result in low excitations, reducing the need for re-initialization of ion states. This can enable a significant improvement in the operation time of an ion-based quantum information processor.
Dr. Bowler Brief Bio:
Dr. Ryan Bowler has been working in the field of atomic, molecular, and optical physics since 2006. He received his B.S. in physics and B.A. in mathematics at the University of Washington. During his Ph.D. work at the University of Colorado, Boulder, his graduate research was conducted at the National Institute of Standards and Technology. There his work focused on quantum computation with trapped atomic ions using laser-driven entanglement, and working on emerging techniques to produce large-scale quantum computer architectures. He performed postdoctoral research at the University of Washington, researching the formation of trapped ultra-cold molecules, and to optically trap mixed atomic samples. Dr. Bowler currently works on photonics with EOSPACE as a member of the technical staff.

What is It?
SpheroFront allows analysis of diffraction in focusing optics and can be used to evaluate the impact of aperture obstructions on the point spread function at and near the focal point in systems ranging from microscopes to telescopes.
- Support for arbitrary aperture masks
- Sensible defaults for angular spectrum sampling and tile summation
- Adjustment of output field size and sampling pitch independent of the input field
- Perceptual rendering under scotopic and photopic vision assumptions
- Control of illuminant colour temperature
- Togglable auto-calculation for interactive use
- Memory requirement estimation
- Intermediate result caching for rapid evaluation of defocus fields
The underlying library is open source and implements the summed field method, a modification of the angular spectrum method, proposed by Hillenbrand et al. The summed field method allows for memory efficient evaluation of apertures with large Nyquist sampling requirements in systems where the power of the output field is concentrated in a relatively small area. The use of the 1st Rayleigh-Sommerfeld diffraction integral provides significant improvements in off-axis accuracy when compared to the simpler and computationally cheaper Fresnel diffraction approximation.

How Does the Cochlear Implant Work?
The cochlear implant bypasses
the damaged parts of the inner ear and directly stimulates the remaining
hearing nerve fibers in the cochlea with electrical signals.
The Cochlear Implant System works in the following manner:
1. Sounds are picked up in the small, directional microphone located in the ear level speech processor.
2. The speech processor filters, analyzes and then digitizes sound into coded electrical signals.
3. The coded signals are sent from the speech processor to the transmitting coil.
4. The transmitting coil sends the coded signals as FM radio signals to the cochlear implant under the skin.
5. The cochlear implant delivers the appropriate electrical signals to the electrode array, which has been inserted into the cochlea.
6. The electrodes along the array stimulate the auditory nerve (hearing nerve) fibers in the cochlea.
7. The resulting electrical signal is sent through the auditory system to the brain where the signal is interpreted. After a period of rehabilitation, these signals are interpreted in the brain as sound.
