NASA chip reflects Wi-Fi to improve your wearable device’s battery life

Atmel | Bits & Pieces


This new technology could reduce the power needed to send information from wearables.

Researchers at NASA’s Jet Propulsion Lab and UCLA are currently working on a Wi-Fi reflector chip that they say would drastically improve battery life in wearable devices by reducing the power needed to transmit or receive information to computers and cellular and Wi-Fi networks.

NASAWifi1

The chip uses existing wireless signals to reflect information back to a router or cell tower instead of the wearable generating the signal itself. According to Adrian Tang of NASA’s Jet Propulsion Lab, not only does this drastically reduce power consumption, the solution also transmits Wi-Fi signal three times faster than traditional Wi-Fi.

Information transmitted to and from a wearable device is encoded as 1s and 0s, just like data on a computer. When incoming energy is absorbed by the circuit, that’s a “0,” and if the chip reflects that energy, that’s a “1.” This simple switch mechanism uses…

IoT platform, Silicon Impulse, energy efficiency and consumer applications focus of LetiDays discussion

Renesas News Articles

Smart devices for the Internet of Things are among the top three growth drivers for the semiconductor industry, but the IoT is a highly fragmented market where multiple applications have varying energy requirements. Speaking at a session on “Consumer & Energy Efficiency” at the LetiDays annual event in Grenoble, France, Edith Beigné, a senior scientist in the Architecture, ID Design, and Embedded Software Department at CEA-Leti, said the fragmentation presents challenges for technology providers, because it is difficult and expensive to design a single chip for one application or to provide a software or hardware platform to cover each archetype. Leti …

Securing Virtual Container-Based Applications

Renesas News Articles

Containerization is an approach to virtualization in which apps and all their components are packaged up and compartmentalized but share a common operating system environment. Since containers share a single OS kernel, they are much more efficient than full hardware virtualization. Containers introduce a revolutionary way to make applications portable and at the same time decrease their virtualization costs by orders of magnitude.

Part 0: Getting started with IoT on AWS and Arduino (+ESP8266)

Syed Anwaarullah

I’ll be doing a series of posts on getting started with building IoT applications using an AWS EC2 Instance and an Arduino with ESP8266 WiFi Module. We’ll eventually delve into Raspberry Pi, MongoDB, Node.js, Dashboards etc as  the journey continues.

The inspiration behind these IoT series is the lack of a true IoT development experience. We usually use Data Endpoint providers like ThingSpeak, Xively etc without knowing what’s happening in the background and how they’re acing it.

We’ll be playing around with PHP, MySQL and Apache on the “Internet” side and Arduino and ESP8266 on the “Thing” side eventually combining them together to build an “Internet of Thing”.

If you already have access to a Website running off a Linux instance (private/shared hosting), you can skip Part 1 and directly jump to Part 2.

In these series, we’ll be covering up the following parts.

  1. Creating an Amazon Web Service EC2 Instance and…

Top 5 Ways Nanotechnology May Change Apartment Living

Remotely Thoughts

Nanotechnology is going to fundamentally change the way we live. Nanotechnology is the science of working with atoms and molecules to build devices or robots that are extremely small. In the near future, nanobots will be able to be swallowed in pill size and will be able to detect and fight off diseases within the body. According to TED Talker and MIT Media Lab founder Nicholas Negroponte, in 30 years, we will be able to swallow pills and ingest information through the blood stream. Take a pill and learn English. Take a pill and learn Shakespeare.

For the apartment industry, here are some nanotechnology predictions that will change the way residents live in apartments.

1) The paint on the walls will be able to turn any color in real time.

Something unexpected happened when scientists …started stringing together nanoparticles of gold.

2) Paper will be replaced by electronic…

IBM launches new Internet of Things community for developers

Renesas News Articles

IBM today announced the launch of a new community, IBM developerWorks Recipes, designed to help developers – from novice to experienced – quickly and easily learn how to connect Internet of Things (IoT) devices to the cloud and how to use data coming from those connected devices. Users of developerWorks Recipes can tap into IBM’s platform-as-a-service, Bluemix, to implement step-by-step tutorials for embedding advanced analytics and machine learning into IoT devices and applications.

Are you really Serious about Security then give something back during Security Serious Week

logo-date+slogan(banner)

Here’s an event that you’re going to want to be involved in because it’s for every company who takes Security Seriously!

The campaign is called SECURITY SERIOUS and we’ve dedicated an entire week to it from 26-30 October.  The campaign will push the message to the business community that – we’re taking Security Seriously and so should you!

We’re hoping to get 50+ best of breed companies who are good at IT security to help other companies become more security savvy through a range of exciting events! We’ll kick off the week with a photocall outside the Tower of London at 12 noon on 26th October.  Everyone will be there with their company logo and huge banner that states that we’re all pulling together to show that “UK PLC is serious about IT security. We’ve arranged for the press to take pictures at the photocall and then we intend…

The Internet of Things, Continued

Better Than the Alternative Blog

car-traffic_z1HStUFd (1)Last week, two white hat, or ethical, hackers, Charlie Miller and Chris Valasek, took control of a Jeep Cherokee being driven by Andy Greenberg, a Wired magazine staffer, from Miller’s home ten miles away.  These are the same two who demonstrated their ability to hack into a vehicle’s OnStar system to override the driver’s actions in order to brake the car. On that occasion, the two were in the back seat of the vehicle. But last week’s report that they were ten miles away illustrates the potential on a much more frightening level.

Fortunately for all, the two were working with Chrysler so that the automaker could develop a fix that can be downloaded onto a USB drive (or can be obtained from Chrysler directly, also on a USB drive). Hopefully the two, or other white hat hackers, will continue to search for opportunities so the defects/bugs/whatever we should call them…
