Abstract:
A device for monitoring belt tension includes two supporting elements for supporting a belt, a deflecting element between the supporting elements, at least one elastic element and a switch. A sufficiently high tension for a belt that is supported on the supporting elements and guided past the deflecting element may be displayed if the deflecting element has been moved in a predefined way against a restoring force of the elastic element, thereby actuating the switch.

Abstract:
A device, method, and system that allows the easy add on attachment of an applied-power sensor, assuring precise measurements over time, even in vibrating environments such as exercise environments. The device possesses structural qualities such that tightening the wrapping latch around a measured object/part presses a loaded spring between the object/part and the sensor, achieving and maintaining sufficient and constant contact, thus allowing continuously precise measuring. The device also includes a transmitter to transmit the measured data to an external data processing device and may include a processor to process the data before transmitting.
Abstract:
A foreign matter detection sensor includes a sensor section, power supply members, a sealing member, and includes an elastic elongated hollow insulating body with separated electrode wires inside the insulating body. The sensor section includes a first end and a second end and detects foreign matter by receiving external force from the foreign matter and being elastically deformed. The power supply members are electrically connected to the electrode wires at the second end of the sensor section via electrode connecting portions. Each power supply member includes a direction changing section, extending from an associated electrode connecting portion in a direction intersecting the longitudinal direction of the sensor section and further extends in a direction toward the first end of the sensor section. The sealing member on the second end of the sensor section seals the electrode connecting portions, the direction changing sections, and one end of the hollow body.
Abstract:
A non-rigid electrical component includes a first layer of a compressible material. The first layer has at least one aperture therethrough. A second layer of an electrically conductive material is positioned on one side of the first layer across the aperture and a third layer of an electrically conductive material is positioned on an opposite side of the first layer across the aperture. The first layer is compressible such that the second and third layers of material may be brought into contact with each other in the aperture of the first layer to complete an electrical connection between the second and third layers upon application of a compression force. The first layer is also made of a resilient material such that when the compression force is removed, the first material expands to separate the second and third layers, thereby breaking the electrical connection.

Abstract:
A load sensing platform (121) is disclosed for capturing a transit time, phase, or frequency of energy waves propagating through a medium that measures a parameter of the muscular-skeletal system. The load sensing platform (121) comprises a sensing assemblage (1), substrates (702, 704, and 706), springs (315), spring posts (708), and spring retainers (710). The sensing assemblage (1) comprises a stack of a transducer (5), waveguide (3), and transducer (6). A parameter is applied to the contact surfaces (8) of the load sensing platform (121). The sensing assemblage (1) measures changes in dimension due to the parameter. Position of the applied parameter can be measured by using more than one sensing assemblage (1). The springs (315) couple to the substrates (702, 704) providing mechanical support and to prevent cantilevering. The spring posts (708) and spring retainers (710) maintain the springs (315) at predetermined locations in the load sensing platform (121).
Abstract:
A pressure testing device for calculating a pressure in a flexible line comprises a housing unit, a force sensor mounted on the housing unit and a clamp assembly having a clamp mounted on the housing unit. The clamp is operable to compress the flexible line against the force sensor by a predetermined degree of deformation of the flexible line. The device includes a displacement sensor adapted to measure a displacement of the clamp. The device also includes a controller having a processor in communication with the force sensor and the displacement sensor, and a memory unit containing stored data. At the predetermined degree of deformation of the flexible line, the processor compares a first signal from the force sensor and a second signal from the displacement senor with the stored data to estimate the pressure within the flexible line.
Abstract:
A push force simulator for measuring a force applied to a first component being attached to a second component with a pressure-sensitive adhesive located therebetween. The push force simulator can include a handheld block having a top surface and a bottom surface, and a palm-simulating polymer layer attached to the bottom surface. In addition, a pushable force gauge having an engagement end engaged with the top surface of the handheld block can be included. The pushable force gauge can measure an amount of force applied thereto, and thus measure the force transmitted through the block, through the palm-simulating polymer layer and applied to the pressure sensitive adhesive.
