Abstract:
1. A motion sensor comprising: an assembly having suspension members, the suspension members isolating the assembly and components mounted on the assembly from vibrations and passing digital signals between at least one component mounted on the assembly and an external controller not mounted on the assembly; a vibrating member mounted on the assembly; a sensor mounted on the assembly for detecting movement of the vibrating member in response to rotation of the assembly, the sensor outputting an analog signal responsive to the rotation of the assembly; and digital electronics mounted on the assembly and coupled to the sensor and the suspension members, the digital electronics including a register that accumulates a programmable number of digital samples of the analog signal from the sensor and transmits, through at least one of the suspension members, digital data indicative of the rotation of the assembly to the external controller, the programmable number of digital samples controlling the bandwidth of the sensor.
