Abstract:
1. A motion sensor, comprising: an output protocol processor coupled to receive a first signal representative of a motion of an object, a second signal representative of the motion of the object, and a vibration signal representative of a vibration of the object, wherein the output protocol processor is operable to generate an object-motion output signal having a variable characteristic that changes after a valid time, wherein, after the valid time, the object-motion output signal is indicative of a speed of movement of the object and a direction of movement of the object, wherein, if the vibration signal is indicative of a vibration of the object during a predetermined number of cycles of at least one of the first or second signals, the output protocol processor is operable to determine the valid time as an end of a determined time period starting at a time of the vibration of the object represented by the vibration signal, and wherein, if the vibration signal is not indicative of a vibration of the object during the predetermined number of cycles, the output protocol processor is operabie to determine the valid time as an end of the predetermined number of cycles.
