Title:
SENSOR MODULE AND COMPUTATION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2024/084956
Kind Code:
A1
Abstract:
This sensor module comprises a sensor that outputs a signal corresponding to deformation of an elastic member, and a computation circuit that receives the signal from the sensor. The computation circuit measures the length of time of a target period in which the signal strength is outside a range defined by threshold values, calculates a signal gradient on the basis of the length of at least one portion of the target period and the amount of variation in the signal in the at least one portion of the target period, and computes a stress value representing the stress applied to the elastic member on the basis of the gradient and the length of time of the target period.
