Abstract: A washer assembly is for use with a fastener. The washer assembly includes a first conductive portion, a second conductive portion, and an insulating portion disposed between the first conductive portion and the second conductive portion. The first conductive portion, the second conductive portion, and the insulating portion form a variable capacitor having a capacitance based on an amount of force applied thereto by the fastener. A wireless transponder unit includes a control unit electrically connected to the variable capacitor and an antenna electrically connected to the control unit. The control unit is configured to sense the capacitance of the variable capacitor, to generate information representing the capacitance, and to output the information to a wireless reader unit via the antenna.

Abstract: A force transducer, in particular a load cell, includes a spring body that deforms when loaded with a force or load to be measured. Two support parts, which are separated by a gap, are moved out of a position of rest. A capacitive displacement detector is used to detect the relative movement of the support parts, where the capacitor includes two electrode combs that are each held on one of the support parts and includes a multiplicity of electrode fingers. The electrode combs are configured designed and mounted on the two support parts such that the electrode fingers of the one electrode comb pass into the finger interspaces of the other electrode comb when the spring body is loaded so that the force transducer is resistant to overloading.

Abstract: A distractor suitable for measuring a force, pressure, or load applied by the muscular-skeletal system is disclosed. An insert couples to the distractor. The insert has at least one articular surface allowing movement of the muscular-skeletal system when the distractor is inserted thereto. The insert can be a passive insert having no measurement devices. A sensor array and electronics are housed within the distractor. The distractor can dynamically distract the muscular-skeletal system. A handle of the distractor can be rotated to increase or decrease the spacing between support structures. The measurement system comprises a sensor array and electronic circuitry. In one embodiment, the electronic circuitry is coupled to the sensor array by a unitary circuit board or substrate. The sensors can be integrated into the unitary circuit board. For example, the sensors can comprise elastically compressible capacitors or piezo-resistive devices. The distractor wirelessly couples to a remote system for providing position and magnitude measurement data of the force, pressure, or load being measured.

Abstract: A flexible force or pressure sensing mat includes a first sheet of electrically conductive first paths, a second sheet of electrically conductive second paths, and a sensing layer positioned between the first and second sheets. The first and second conductive paths are oriented transversely to each other, and the locations of their intersections define individual sensing areas or sensors. The sensing layer is made from materials that have first and second electrical characteristics—such as capacitance and resistance—that vary in response to physical forces exerted thereon. A controller repetitively measures the multiple electrical characteristics of each sensor in order to produce a near real time pressure distribution map of the forces sensed by the mat. The mat can be used on a patient support surface—such as a bed, cot, stretcher, recliner, operating table, etc.—to monitor and help reduce the likelihood of a patient developing pressure ulcers.

Abstract: A sensor for monitoring external loads acting on a pin assembly includes a pin having an axial interior bore defined therein and having a length defined from a first end to an opposed second end thereof. A core pin is mounted axially within the interior bore of the pin spaced radially inwardly from the interior bore for relative displacement with respect to the pin. A capacitor is provided having an inner capacitor plate mounted to the core pin, and an outer capacitor plate mounted to the pin, such that relative displacement of the core and the pin due to external loading on the pin results in relative displacement of the inner and outer capacitor plates. The capacitor is configured and adapted to be connected to an electrical circuit to produce signals indicative of external loading on the pin based on relative displacement of the inner and outer capacitor plates.
