The process involves exciting a vibrant device by combining control signals having an amplitude control signal, a rotation control signal around a gyroscopic axis and an amplitude modulated quadrature control signal. A vibration of the device is measured a...

The device includes a base (1), with guides for guiding the rechargeable apparatus towards the connection unit to the battery charger. There are units adapted to receive, in a movable fashion, a connection plug (13) connecting to the external battery charg...

Method involves generating a value for the weight of air flow across a butterfly valve (8) as a function of the amount pumped and with a transfer function (22) inverse to the transfer function of the inlet manifold (23) downstream of the valve. The positio...

Detection and emission modules (3) respectively installed on several wheels (2) of the vehicle (1) are capable of emitting a signal including an indication of a state of the wheel. The captured signal is compared to several waveforms respectively stored in...

A lighting system, typically a vehicle signaling light has a light source (S) and lens (18). The lens has an internal radial rib with optical fibre (20) which acts as a light guide and channels light from the lens center through a further optical fibre to ...

Circuits (15,16) compare the output signal of an odometer (7) with a memorized threshold (14) and issue a signal to the driver if the threshold is passed. In addition the measured value is stored in the memory.

Gyrometer comprises a fiber optic ring with a fiber optic coil (4), an electromagnetic wave source (1) that has a doped optical fiber (8) with a separator for sending two counter propagating waves from the source into the coil and a detector (2) for receiv...
