摘要:
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.
摘要:
A device for counting rotations of an object in a referential, in which a magnetic sensor linked to the object measures a field associated with the referential in order to generate measuring signals at the rotational frequency of the object. The sensor also functions as an antenna for receiving an electromagnetic wave. A method for controlling a counting device includes receiving measurement signals and a radio-frequency triggering signal from a sensor and sending information representative of the numbering cycles in the measurement signals.

The present invention relates to an autonomous device which is intended to be carried by a tire and wheel assembly in order to detect revolutions of said assembly, comprising at least one sensor which produces signals and an interpreter device which is connected to the sensor in order to interpret the signals produced by the sensor. The sensor is a passive sensor, the produced signals of which are proportional to the temporal variations of a magnetic flux though this sensor, and is intended to be integral in rotation with the tire such that the revolutions of said assembly correspond to the revolutions of said sensor. The invention likewise relates to an assembly provided with an autonomous device which permits detection of revolutions of the assembly, and a method for detecting revolutions of the assembly.
