Patent ID: 7889078

Claim:
An apparatus for registration of motion, comprising: a sensor for generation of an electrical sensor signal due to external influences, the sensor comprising piezoelectric material where the signal is generated as a result of a deformation of the piezoelectric material due to force being exerted on the piezoelectric material; first circuits with a relay effect and with substantially no power consumption in a non-activated state and activated by a signal from the sensor, and then drawing power from a voltage source for the apparatus and at the same time providing current to succeeding second circuits; the second circuits comprise a microprocessor for treatment of an amplified signal and generating commands that involve a control voltage; third circuits for communication of signals based at least on one of the generated commands and the treated amplified signal; and fourth circuits for further communications; wherein the first circuits comprise a holding amplifier that can be in two states: 1) a first state—repose state—where a power drain of the holding amplifier is sufficient for activation due to a small voltage pulse emitted from the sensor and the amplification of the pulse to activate the second circuits, and 2) a second state—active state—where the holding amplifier consumes power at a higher rate from a nominal power source and a larger amplification, where transfer from the first to the second state is controlled by the activation of the second circuits, and the second circuits comprise activation circuits which are connected to the sensor and has a security circuit that can be set to block a first activation due to a voltage pulse from the sensor, and thereafter open the blockage and permit a subsequent activation as a result from a second pulse, so to prevent recording of a movement of the apparatus if certain criteria are not met, and further, the apparatus includes measures for remote identification for activation/deactivation from a distance.
