Proposed FCC rules may smooth path to 5G wireless tech for US.

Standard

Mobile network traffic is heading in a direction that pleases many in the wireless industry. The Federal Communications on Thursday proposed new rules in wireless frequencies above 24 GHz.

The FCC news release read: “The FCC took steps today to maintain United States leadership in wireless by proposing new rules for wireless broadband in wireless frequencies above 24 GHz. These proposed rules are an opportunity to move forward on creating a regulatory environment in which these emerging next-generation mobile technologies – such as so-called 5G mobile service – can potentially take hold and deliver benefits to consumers, businesses, and the U.S. economy.”

It was previously assumed physical and tech limitations
could not support mobile service in these bands. New tech developments may allow the use of these high frequencies for mobile applications – like 5G service – with significantly more capacity and faster speeds for next generation mobile service.
Building off of years of successful spectrum policy, this NPRM proposes to create new flexible use service rules in the 28 GHz, 37 GHz, 39 GHz, and 64-71 GHz bands. The NPRM proposes to make these bands available using a variety of authorization schemes, including traditional wide area licensing, unlicensed, and a shared approach that provides access for both local area and wide area
networks.

Material Found that cools your Buildings and throw heat out in SPACE.

Standard

A new material that requires no electricity uses the universe as a heat sink—even when the sun is shining.

A material that simultaneously reflects light and radiates heat at frequencies that vent it through the Earth’s atmosphere could one day help cool buildings on hot days. The material cools itself to a temperature below the ambient air, and has been tested on a rooftop at Stanford University by its inventors, who are now working on scaling up the design.
The new material uses optical engineering tricks to behave in ways that are counter-intuitive and, at first glance, appear to violate the laws of thermodynamics, says Stanford electrical engineer Shanhui Fan, who developed it.

Usually the way to let something cool off is to put it somewhere cold; the hot object will radiate its excess heat into the surroundings. Fan’s material becomes cooler than its surroundings by reflecting light and emitting heat at carefully tuned frequencies. The material emits heat at frequencies that match the planet’s “thermal window”—from eight to 13 micrometers—which lets it pass through the atmosphere and into space. It effectively cools down by using outer space as a heat sink.

For decades, researchers have been exploring this effect, called passive radiative cooling, to try to make systems that cool buildings more efficiently by radiating heat at night. And like Fan, some have succeeded in making materials that emit heat in the thermal window.

Fan figured out a way to make a material that not only radiates in the thermal window, but reflects light like a mirror. He made the material by layering thin films of alternating layers of silicon dioxide (glass) and hafnium oxide deposited on an eight-inch silicon wafer. The material reflects 97 percent of sunlight and releases heat in the thermal window.

ShopSecure the smart alternative for CCTV

Standard

ShopSecure


The distribution partners of Knewron, S.V. TechnoCrafts, were approached by shop owners in their area who said that many of them were desperately looking for something which could serve as an effective alternative to CCTV cameras and be economical for their pockets. “This critical need prompted us to work on a solution that could serve the purpose with the help of technology at hand,” says T. Anand, the co-founder of Knewron.

Imagine a device that is user-friendly, economical, reliable, records the video round the clock, does some analysis by itself, detects suspicious activities and takes precautionary measures. You need an active system for fulfilling these conditions and ShopSecure is one such system. It can detect malfunctioning or suspicious incidents and report or act accordingly. ShopSecure would not wait until the footage is analysed by the user, but it will intimate them instantly of security breach and can also sound an alarm to scare away intruders.

Working
ShopSecure belongs to the Internet of Things (IoT) device line with fundamental IoT qualities. Basically it is an M2M communication model which is interoperable in nature. It involves uniquely addressable physical entity connected in local/private or cloud network for effective functioning. The device activity log can be streamed over the Internet and later analysed by users. The device can operate autonomously with Internet Bridge over cloud (with GPRS or 3G) or in direct contact mode (with GSM module).

All the intelligence and processing of ShopSecure comes from Atmel’s 8-bit AVR microcontroller core around which this device is built. Temperature sensor, audio playback and battery changeover recharging unit are the other key components of this device.

The device is equipped with infiltration sensors (MEMs, reed switches or micro-switches, etc) which actively monitor environment and doors/windows when armed. It is designed to intimate the user when it senses anything out of the ordinary, like a sudden rise in temperature, and it can take appropriate predefined actions. ShopSecure can be remotely controlled and configured and is constructed from some of the commonly available sensors and other components, thus making it low-cost. Its configuration and operation are so simple that, if you can use a mobile phone, you can use it.

In case of devices deploying CCTVs or IR sensors and other proximity sensors, sensitivity is a matter of specification. The sensors deployed in ShopSecure are based on make-break mechanism and hence oblivious of sensitivity.

Customisation
ShopSecure is a customisable equipment. It allows for the installation of various types of sensors for detection of breach as per customer requirements and suitability of application. These sensors then form input to ShopSecure for further processing. The device is mostly put in sleep mode. An abnormal activity is detected depending upon sensor outputs and ShopSecure configuration. Whenever any problem is detected, the device would alert user(s) with an SMS and a phone call to the predefined numbers with audio playback stating the emergency. The users can also opt for the device to directly call authorities (police or fire brigade) regarding the incident.

The gadget is provided with two modes of operation: Stealth mode and Shout mode. In Stealth mode, if intrusion is detected, ShopSecure would silently inform users about the incident and then they can rush towards that particular region and perhaps catch the intruders in action—red handed. However, in cases where the user is far away, it can be switched to Shout mode. Here, when intrusion occurs, an alarm is sounded to scare away the intruders and simultaneously inform users about the incident. It is the Stealth mode of ShopSecure which makes it special compared to other similar products available in the market.

Design challenges
Being an IoT product, the main challenge during the design of ShopSecure was the need for a software that offers crash-free operation and provides as much up-time for the device as possible.

The team listed as many failure modes as possible that ShopSecure could face during its operational life cycle. Then they worked on reducing the risks related to each one. “That was perhaps the longest part of the development cycle; however, it was the critical one and useful one too,” says Anand, managing director, Knewron.

Another challenge was system recovery under crash conditions. The team had to work on how ShopSecure would respond to unauthorised access and how it would recover from the crashes caused by this or any other reason. Significant portion of software addresses this part now.

Besides, providing audio calling facility in regional language was another challenge. It was a tricky issue to sync audio playback with automated phone calls. The company currently offers only Hindi or English versions of audio playback for simplicity and to keep the costs low.

Since ShopSecure has rechargeable battery as a backup option, power consumption has to be very low to ensure reliable uptime for longer hours. Optimisation of system resources to consume lowest power possible was yet another issue that had to be taken care of.

Since the product was developed keeping in mind the local shop owners, the overall cost was to be closely monitored during development, and the team was successful in making it affordable.

In all, it took around five months to get ShopSecure from idea to a finished product.

IBM again on hot wheels, this time by announcing its human brain like chip

Standard

International Business Machines (IBM) has unveiled a “brain-like” computer chip that is the size of a postage stamp and capable of processing massive amounts of data while handling inputs from many different sources, the company said.

The announcement comes one month after IBM unveiled a $3 billion investment over the next five years in chip research and development to find a game-changing breakthrough that can help revive its slumping hardware unit.

Unlike most chips, which operate on pre written paths, IBM’s version processes data in realtime and is capable of dealing with ambiguity, the company said. It runs on the energy equivalent of a hearing aid.

Built on Samsung Electro-Mechanics Co Ltd’s 28nm process technology, the chip only consumes 70mW of energy.

A product of almost a decade of research, the chip aims to bridge the divide between existing computers and the brain’s high cognitive power and low energy use.

“After years of collaboration with IBM, we are now a step closer to building a computer similar to our brain,” said Professor Rajit Manohar at Cornell Tech, where the chip was designed.

The chip contains one million programmable neurons and could allow a thermometer to scan and smell chemical signals and deliver a diagnosis, or help a search and rescue robot to identify people in need during a disaster, the company said.

IBM hopes it can integrate multi-sensory processing into mobile devices and says the chip can handle future advances in memory, 3G integration, logic and sensor technologies.

Here comes the newer concept of supercapacitor to store energy via running electric cables.

Standard

One of the fundamental challenges of battery technology is that lithium-ion batteries — by far the best general option for energy storage currently in wide commercial use — are intrinsically bulky and heavy. A new research team at the University of Central Florida believes they can challenge that problem by turning copper wires into supercapacitors, then embedding those wires into the fabric of your clothing or the body of a device. In theory, they could also be embedded throughout the body of a car, significantly boosting total energy storage and freeing up space in the trunk.

According to nanotechnology researcher Jayan Thomas, his work on the concept involves first heating copper wire to create nano-whiskers — nanoscale-sized tendrils of metal that split off from the main wire. These are then protected by a sheath of naturally forming copper oxide (produced when the wire is heated in air). This turns the nanowhisker into an electrode. The entire structure is then wrapped in a plastic sheath, with a second set of nanowhiskers. The end result is a layered structure that looks like the feature image above — the copper wire in the center still conducts power, but the nanoscale structures store additional electricity as well.

Supercapacitor or battery?
Some write-ups are describing this as a type of battery, but the authors refer to it as a supercapacitor, and that designation appears to make more sense. The difference between supercapacitors and batteries, from a functional standpoint, is that batteries can store significantly more energy than a supercapacitor, but cannot release that energy nearly as quickly. Supercapacitors store less energy in total, but can discharge it nearly instantly. Supercapacitors tend to make poor batteries and vice versa, despite continuing research to find a way to blend the two.
The real question is how much energy can be feasibly stored in this type of copper wire and how effectively the nanostructures can be recharged without degrading. While the author talks of weight and bulk savings, copper is significantly heavier than metals like aluminum, and the extra shielding required will have its own weight. This ability to embed supercapacitor capability into virtually any surface could have a significant impact in some fields, but only if it winds up saving space or weight compared to existing methods. Efforts to incorporate traditional lithium-ion batteries into flexible cables have also been developed; LG demonstrated this type of structure two years ago.
