The Wireless Sensor Network Research Group (WSNRG) has created a small device called X-Tick to help researchers who are involved in the indoor location field to develop their own triangulation algorithms. It can be programmed to send messages with different power levels periodically or when moving its internal Joystick (events oriented). SquidBee motes can be used to retrieve these packets and to see the Received Signal Strength Indicator (RSSI) they have. You can read the related article here.

A great post written by Roger Meike about teaching physics using wireless sensor networks. He used Sun SPOTs and a little bit of science magic to give kids a ball that could tell them how high they could throw it. To achieve this, he embedded a Sun SPOT in a foam football. He set up that Sun SPOT to stream accelerometer data to the base station and then had a host side application that could tell how high the ball was thrown.
The experiment, as well as the code, can be found here.
Sensinode Ltd., a pioneering commercial supplier of solutions for Internet Protocol (IP) based wireless mesh networks, today announced the release of a new software stack, wireless router and mesh gateway for M-Bus (Metering Bus). These new products extend the power of wireless sensor technologies in both near- and mid-range applications; including Advanced Metering Infrastructure (AMI) and smart object applications in very low power distributed networks based on Texas Instruments’ low-power RF devices for 868/915 MHz and 2.4 GHz frequency range in module form factor from Radiocrafts.

MIT researchers and colleagues are working to find out whether energy from trees can power a network of sensors to prevent spreading forest fires. What they learn also could raise the possibility of using trees as silent sentinels along the nation’s borders to detect potential threats such as smuggled radioactive materials.

THE Australian Institute of Marine Science has begun using one of the world’s first reef-based internet protocol networks to monitor the impact of destructive forces on the Great Barrier Reef.
Using waterproof Next G modems, adaptive sensor equipment and solar-powered buoys to float the devices, AIMS has installed two wireless IP networks that can transmit data in real time up to 100km offshore.

The Sensors & Instrumentation KTN have pleasure in inviting you to a free knowledge exchange and partnering event on energy harvesting technologies organised by the Sensors & Instrumentation Knowledge Transfer Network on 26 November 2008 at the Institution of Engineering and Technology in London.
This event brings together organisations that are either developing or commercialising energy harvesting technology solutions with potential users of the technology. We have secured speakers from the leading energy harvesting companies in Europe and academics covering various aspects of the technology. Presentations will cover the range of different energy harvesting techniques and describe a number of different applications.
