Patent ID: 8450996

Claim:
A motion sensor, comprising: a plurality of magnetic field sensing elements configured to generate a plurality of magnetic field signals indicative of a magnetic field associated with an object; and a respective plurality of state processors, each state processor coupled to receive a signal representative of a respective one of the plurality of magnetic field signals, wherein each one of the plurality of state processors is configured to generate a respective STATE_SM signal indicative of a plurality of states associated with a respective one of the plurality of magnetic field signals, wherein each one of the plurality of states is indicative of a respective range of signal values, wherein the STATE_SM signal comprises a plurality of first direction state transitions and a plurality of second direction state transitions, wherein the plurality of first direction state transitions and the plurality of second direction state transitions of the STATE_SM signal comprise state transition chatter, and wherein each one of the plurality of state processors comprises: a respective state peak logic module coupled to receive the respective STATE_SM signal and configured to generate a respective STATE_PEAK signal, wherein the STATE_PEAK signal comprises a plurality of first direction state peak transitions and a plurality of second direction state peak transitions, wherein the plurality of first direction state peak transitions and the plurality of second direction state peak transitions of the STATE_PEAK signal comprise reduced state transition chatter.
