The processor then hung too close to the fan, its heat causing a sensor to go off which automatically shut down the server.

Based on the Phoenix lander, the craft is tasked with giving us a peek beneath the planet's surface, armed with tools that include a geodetic instrument from the Jet Propulsion Laboratory, which will be used to calculate Mars' rotation axis, a seismic wave sensor and a subsurface heat probe, to measure the planet's internal temperature.

The material uses what the researchers are calling 'shape-memory' polymers and have a fiber optic network embedded within them which acts as the damage sensor as well as the heat delivery system.

For now, the basic CORE 2 model comes with an adjustable elastic band (available in multiple colors) and a sensor module packing an accelerometer and three heat and skin sensors.

It also uses an accelerometer and light sensors to snap an image when a person enters a new environment, and an infrared sensor to take one when it detects the body heat of a person in front of the wearer.

It also features a boil sensor which helps eliminate boil-overs by alerting the user or automatically reducing heat to a pre-set level.

Unlike almost all competitive products that use only one sensor to 'read' the body, BodyMedia's monitors incorporate temperature, heat flux, galvanic skin response and 3-axis accelerometer sensors to get accurate measurements of calorie burn, exercise intensity and sleep patterns that affect weight as well as health.
