Force measurement systems and methods are disclosed for accurate real-time measurement of forces. The system is configured to measure force as a function of time. The system may comprise a handheld device capable of measuring a force externally applied to opposing surface regions thereof for the purpose of monitoring or directing isometric exercises for personal wellness. Additionally, the system may be configured to communicate force measurement data to a remote device or server.

Disclosed is an assembly of a non-magnetic and metallic target for an inductive sensor and its support, the target being flexible under pressure and under the release of the pressure in a reciprocating movement toward and away from the support. The target includes a central portion surrounded by flexible fixing tabs, a first end of which is secured to the central portion and a second end of which is fixed to the support, the fixing tabs being evenly distributed around the central portion, a first portion of each fixing tab closest to the central portion being stiffer relative to a portion of the fixing tab farthest away from the central portion.

A weight sensor may include a weighing platform and a load cell coupled to the platform to sense a weight applied to the platform, the load cell may include a deformable plate with one or more strain gauges arranged to provide an electrical signal representing the weight applied to the platform, and a base supporting the load cell, wherein the deformable plate is movably mounted to the base at only three contact points, the contact points allowing lateral movement of the plate when the plate deforms in response to a weight applied to the platform. The weight sensor makes it possible to monitor the weight and weight shifting of two people sharing the bed. The weight sensor is self-centering when a load is applied off-center to the platform, which is beneficial when used underneath a bed, e.g., under a bed leg or other support member which may not be aligned.

A monitoring system for an archery bow is provided. Monitoring devices and methods are also provided.

A method of adjusting the parallelism of a surface of a block of optical fibers with a surface of a semiconductor chip or wafer laid on an XY table, including the steps of: a) providing a sensor rigidly attached to the XY table and a handling arm supporting the block, said surface facing the XY table; b) for each of three non-aligned points of the surface of the block, displacing with respect to each other the XY table and the block in the X and/or Y directions to place the sensor opposite the point, and estimating, with the sensor, the distance along the Z direction between the point and the sensor; and c) modifying the orientation of the block by means of the handling arm to provide the desired parallelism.
