The electronic circuit (1) makes it possible to drive a resonator (2) of a MEMS resonator device. The resonator comprises a mass (m) connected to a spring (k) and a damping element (d), an activation element (C act) to activate the mass by an activation si...

The device has front and back substrates (3,4) fixed on each other by sealing frames (7, 7), and liquid crystals (6) filling a space between the substrates and frames. An additional layer (8) has same color as that of the device in an inactive state, viewe...

A road lane marking crossing detection system has sensor units (2) with a light source and optical splitter, and lens chain integrated in the casing to produce two light beams (4, 6) lighting separate areas (10, 12) of the road (8), and a photo-detector se...

The portable receiver is carried by a car driver to enable operation of the anti-theft system. It comprises two antennae (10,20) orientated along different axes, each connected to a phase-shifting circuits (12,22). A multiplexing circuit (24) combines the ...
