Mechanical switching means for providing shunt calibration in a rotary transformer system

Patent number: 4567377

Abstract: A system for calibrating a strain gage transducer mounted on a rotating member comprising a mechanical switch capable of making contact from a stator to selected terminals on the rotor to provide both positive and negative shunt calibration of the transducer. In a first embodiment, calibration is carried out while the rotor is stationary, providing a simple, cost effective calibration system for most applications. In a second embodiment, special terminals permit contact while the rotor is in motion. In a third embodiment, simultaneous calibration and gage measurements are possible while the rotor is in motion providing a means of continuous correction which is especially advantageous in applications where the rotor is subject to a rapidly changing environment.

Tactile load sensing transducer

Patent number: 4621533

Abstract: A tactile load sensing transducer for providing a continuous electrical readout indicative of the contact and the location of the load on a load receiving plate substantially simply supported by a plurality of reaction supports on the member. Each reaction support includes a member having a preferably integrally formed connecting portion of reduced transverse section so as to be substantially incapable of resisting moments generated by load plate deflection. Each support preferably has a generally “L” shaped configuration with the preferably integrally formed plate connecting portion formed adjacent the free end of one leg of the “L” so as to create bending strains in the support. Strain gages are provided on each support to sense the bending strains therein and, the gages on each support are connected in a common Wheatstone bridge to provide an indication of the reaction load on the support.

Tactile sensor

Patent number: 4616511

Abstract: A load plate is rigidly supported by a central pedestal strain gaged for bending about a central axis. In one embodiment, the pedestal is mounted to the center of a yoke bar supported by two legs strain gaged for comprehensive loads only the sum of which is indicative of the magnitude of the plate load. The legs are supported by base webs strain gaged for bending about a central axis orthogonal to the axis of pedestal bending. The output of the bending strain gages enables determination of the coordinates of the load location on the plate from the central axis axes.In a second embodiment, the pedestal is supported by a block rigidly attached to the end of a cantilevered member extending at right angles from the pedestal. The cantilever member is strain gaged at two longitudinal stations for reading the differential of the bending strain to thereby determine the shear loading, or plate tactile load.
