Abstract

A sensor unit, and a housing-relay for the production of said unit. A sensor unit for roller skates, skateboards or cycles, comprising a detector consisting of at least one sensor and a primary emitter, said emitter being able to emit a primary signal from a measurement signal provided by the sensor; a remote housing-relay which can be worn by a user, comprising a primary receptor which can receive the primary signal and a secondary emitter which can emit a secondary signal; in addition to a remote display which can be worn by a user, comprising a secondary receiver which can receive the secondary signal and a display device.

Claims

1. A sensor unit for roller skates, skateboards or cycles, comprising a detector comprising at least one sensor capable of providing a measurement signal representative of at least one wheel rotation parameter, and a primary transmitter said primary transmitter being capable of transmitting a primary signal based on a measurement signal provided by the sensor, the sensor unit further comprising a remote housing-relay intended to be placed on a limb of a user, a shoe, a roller skate, a skateboard or a cycle frame, said housing comprising a primary receiver capable of receiving the primary signal and a secondary transmitter capable of transmitting a secondary signal corresponding to the primary signal, and a remote readout element intended to be worn by a user, said readout element comprising a secondary receiver capable of receiving the secondary signal and a display device.

2. The unit as claimed in claim 1, wherein the detector is attached in a wheel.

3. The unit as claimed in claim 1, wherein the detector is attached to an axle used for the rotational mounting of a wheel.

4. The unit as claimed in claim 3, wherein a transmitter of the detector is mounted nonrotatably on the axle.

5. The unit as claimed in claim 1, wherein the primary transmitters comprises a processing stage capable of providing a primary signal encoding the measurement signal and a primary identification code, the housing relay comprising a processor unit capable of identifying the primary signal according to said primary identification code.

6. The unit as claimed in claim 1, wherein the housing-relay comprises a processor unit capable of providing a secondary signal encoding a measurement signal and a secondary identification code, the secondary receiver comprising a processing stage capable of identifying the secondary signal according to said secondary identification code.

7. The unit as claimed in claim 1 wherein the housing-relay comprises an accelerometer and a processor unit capable of processing a measurement signal of the accelerometer and of causing the transmission of a corresponding secondary signal to the readout element.

8. The unit as claimed in claim 7, wherein the housing-relay comprises selection means for the transmission of secondary signals according to an accelerometer or according to a primary signal.

9. The unit as claimed claim 1, wherein the housing-relay is furnished with removable attachment elements.

10. The unit as claimed in claim 1, wherein the readout element is furnished with means of direct attachment to the user and/or an item of the user'"'"'s equipment, such as a cycle frame.

11. A housing-relay for the production of a unit as claimed in claim 1, comprising a primary receiver capable of receiving primary signals encoding a measurement signal and a primary identification code, a processor unit capable of extracting the measurement signal from the primary signal and of forming a secondary signal encoding the measurement signal and a secondary identification code, and a secondary transmitter for the transmission of said secondary signal.
