Method and system for zero-resetting of a torque-measuring device, especially on a cycle or like vehicle
First Claim
1. A method for zero-resetting of a device for measuring transmitted torque during use of a cycle equipped with said device and having a driving wheel fitted with a free-wheel mechanism, wherein:
- a monitoring operation is applied to a phenomenon or a parameter which is normally variable during normal use of the cycle and which disappears or becomes constant when the driving wheel rotates in free-wheel motion, andwhen the disappearance or the constant character of the phenomenon or of the parameter thus monitored is observed during a predetermined period of time, initiating zero-resetting of the torque-measuring device.

Abstract
A method for zero-resetting of a device for measuring transmitted torque while a cycle is in motion consists in monitoring a phenomenon or a parameter which is normally variable during normal use of the cycle and which disappears or becomes constant when the driving wheel rotates on free-wheel motion. When the disappearance or the constant character of the phenomenon or parameter thus monitored is observed during a predetermined period of time, one initiates zero-resetting of the detector system or of the measuring system proper of the torque-measuring device. The device for carrying out the method includes on the one hand a monitor for the phenomenon or parameter and on the other hand a control which are operated in dependence on the signal emitted by the monitor and which are then capable of producing action on the detection system or the measuring system in order to reset either of these two systems to zero.

4. A system for automatic zero-resetting of a device for measuring transmitted torque which is fitted on a cycle having a driving wheel provided with a free-wheel mechanism, wherein said system comprises in combination:
-
means for monitoring a phenomenon or a parameter which disappears or becomes constant when the driving wheel rotates in free-wheel motion, these monitoring means being capable of emitting a predetermined signal when this event takes place during a given time interval, and control means which operate in dependence on the signal emitted by said monitoring means and are then capable of producing action on the torque-measuring device in order to initiate zero-resetting of the torque-measuring device. - View Dependent Claims (5, 6)
