A computing device monitors support element strain to enable deployment of positionally-related components in conjunction with one another while the real-time positional relationship between these positionally-related components fluctuates during operation. An exemplary computing device includes a first component and a second component that are both mounted to a support element. The computing device may be subjected to mechanical loading during operation which may induce strain into the support element thereby affecting the nominal positioning between the positionally-related components. The computing device includes a displacement sensor to generate displacement data that is indicative of a real-time positional relationship between the components. This real-time positional relationship may be compensated while implementing desired functionality. In this way, the computing device can be subjected to the stresses and strains that result from many typical use cases while the positional relationship between the sensor components is actively monitored and compensated for to implement desired functionality.

A hitch force monitoring system includes a hitch ball having a stem downward mountable to a vehicle drawbar. Two or more sensors are attached to the stem to respectively measure longitudinal and lateral forces on the hitch ball. A controller is communicatively coupled to the two or more sensors to receive the measured longitudinal and lateral forces and the user interface. The controller is communicatively coupled to a user interface device to indicate the measured longitudinal and lateral forces on the hitch ball that represent push, pull and sway forces of a trailer load attached to the hitch ball.

A device to sense degree of twist in a screwdriver and the magnitude of force applied includes a contacting portion, a deformation portion, a sensing portion, and a processor. The contacting portion receives a grip and twist pressure through the deformation portion which is tiltedly fixed to the contacting portion.

The sensing portion detects a deformation of the deformation portion and generates a corresponding electrical signal. The processor receives the signal and determines the values of the twist caused and the force applied.
