20060140332 - Counting scheme with automatic point-of-reference generation: A counting scheme for a non-volatile counter includes automatic point-of-reference generation implemented in a state machine. Two state variables are used to store the rotation history of the magnet. One variable stores the previous position of the magnet and the other stores the net angle traveled by the magnet from...

20060140331 - Non-volatile counter: A non-volatile counter circuit includes a state machine having a first input for receiving one or more control signals, a second input for receiving a current count value, a third input for receiving historical information, and an output for providing a next count value and an up/down control signal, and...

20060133560 - Counter device and counting method: A counter device includes: a rewritable counter having a non-volatile memory which requires sector erasure to once turn all data in a sector into high data, prior to changing low data into high data in respective bits; and a control section updating a counter value of the rewritable count by...
