If someone had suggested 20 years ago that a fully working computer with up to 1GHz of processing power would fit on a board the size of a SODIMM memory module (2.66 x 1.44 x 0.2 inches), some lighthearted mockery may have followed. Yet embedded hardware specialist Toradex is about to do just that with its new Tegra T20, a teeny computer module based on NVIDIA's latest Cortex A9 processor that offers full high definition video support, 256MB of onboard memory and a gigabyte of Flash storage.

Qi wireless power specification to standardize wireless charging

By - July 27, 2010 1 Picture
As the number of portable electronic devices we carry around has multiplied, so too have the chargers we need to keep them running. Over the last couple of years wireless chargers such as the PowerDisc and Powermat have started popping up to save users the hassle of dealing with a mass of charger cables, but these require specific adapters for the different devices being charged. A business alliance of 20 firms has banded together to form the Wireless Power Consortium (WPC) to develop open standards for wireless charging and has just finalized its Qi low power standard that is aimed at delivering wireless charging stations that can charge a range of compatible devices.

New software lets PCs work while they sleep

By - June 24, 2010 5 Pictures
A particularly troubling aspect of enterprise computer deployment is the need for end user machines to remain switched on day and night. Fully on mind you, not in low power sleep mode. Computer scientists from the University of California, San Diego have developed a software solution which allows PCs to remain on the network even when placed in sleep mode at the end of a working day. The software creates a virtual representation of the computer on the server to handle many of the common overnight tasks, only waking up the physical machine at pre-programmed commands or when it encounters something that it can't deal with itself.

Researchers harness heat to power electronics

By - February 17, 2010 1 Picture
Efforts to capture energy from the human body usually focus on harnessing the kinetic energy of the body’s movement. However the human body is also generating energy in the form of heat that could also be used to run low power electronic devices. New energy-scavenging systems under development at MIT could generate electricity just from differences in temperature between the body (or other warm object) and the surrounding air. Read More
