Electronic device for counting and storing the number of rotations of an object and the number of counter resets
First Claim
1. An electronic device for counting the number of rotations of an object in a frame of reference including a magnetic field, the electronic device rotating with the object and including a coil configured to act as a magnetic sensor, the device further comprising:
- storage means for holding counting information intended to represent the number of rotations counted at any time; and
means for conditional resetting of the storage means adapted to reset the storage means if and only if at least two separate conditions are simultaneously satisfied, wherein at least one of the conditions comprises the reception of information contained in an electromagnetic signal emitted from an external device, and a second condition comprises application of a voltage,wherein the coil is configured to send measurement information to a microcontroller in a first frequency band and configured to act as an electromagnetic antenna receiving information in a second frequency band.

Abstract
A device for counting the number of rotations of an object in a system, in which a storage means carries counting data designed to represent the number of rotations counted. The counting data is used for conditionally resetting the storage means if and only if two separate conditions are fulfilled, where at least of one of the conditions is the reception of information from an external device, thereby insuring that the counting data represents the number of rotations counted from a predetermined time.
