Zenros, a start up in Denmark has created a new solar powered energy management system for hotels they believe will save hotels at least 35% in HLP costs over current sensor based technology.

Researchers from Dartmouth have come up with a new way to provide health monitors just such an ability using a tiny electric current and a bioimpedance sensor.

This reduced current is detected by the sensor via the gold electrode.

With no sight, it detects movement with a tiny sensor in its nose, which picks up the electrical current of its prey.

The sensor also compresses the images it captures in contrast to current compression systems, which only squash images after they are taken.
