Abstract: A torque meter includes a casing and a part is configured to move in the casing in translation in a longitudinal direction under the effect of an axial thrust representative of the torque to be measured. The torque meter further includes a bearing surface connected to the casing via at least one of the ends thereof. The bearing surface extends at least partially in a plane that is substantially perpendicular to the longitudinal direction. One longitudinal end of the movable part is configured to be brought into contact with the bearing surface so that a longitudinal displacement of the movable part leads to a deformation of the bearing surface. The torque meter also has a device configured to measure the deformation of the bearing surface.

Abstract: A bicycle rear hub includes a hub spindle, a drive part, a hub shell and a driving force measuring part. The drive part is rotatably supported on the hub spindle, and configured to receive a driving-force-input member. The drive part includes a coupling part having a liquid storage area filled with a liquid. The hub shell is rotatably supported on the hub spindle and operatively coupled to the coupling part of the drive part for rotation by the drive part on the hub spindle. The driving force measuring part includes a liquid pressure sensor that detects pressure of the liquid in the liquid storage area of the coupling part of the drive part.

Abstract: A torque detection device for a power steering which is less liable to be influenced by external factors or by a bending force exerted on a shaft. In the torque detection device, a torque is generated between an input shaft, which is turned interlockedly with a steering handle for operating the traveling direction of a vehicle, and an output shaft turned interlockedly with the input shaft so as to steer the vehicle. An assisting force is exerted on the output shaft by an assisting unit that is determined based on the detection result. The torque detection device is provided between the input shaft and the output shaft and includes a cam mechanism by which a torque generated between the input shaft and the output shaft is converted into a thrust force, and a pressure sensor for detecting the thrust force into which the torque is converted by the cam mechanism.

Abstract: A torque monitoring apparatus for monitoring torque between a driving structure rotating about a first axis and a driven structure rotating about a second axis. The torque monitoring apparatus includes a piston and cylinder assembly. The piston is received in an aperture defined by the cylinder. At least one of the piston and the cylinder is operable for connection to one of the driving structure and the driven structure and rectilinearly moveable along the first axis or the second axis. The aperture is centered on the axis of rectilinear movement.

Abstract: An easily packaged torque monitoring system accurately captures driveline torque data for use by engine, transmission or other vehicle controllers. The torque monitoring system utilizes a structural member to hydraulically connect a driving member with a driven member. A pressure-sensing device is operatively connected with a fluid chamber in the structural member through which the driving member drives the driven member. The pressure-sensing device senses a pressure level within the chamber. The amount of torque transmitted from the driving member to the driven member is directly linearly related to the sensed pressure. In one embodiment, the pressure-sensing device is a surface acoustic wave sensor in contact with the hydraulic fluid that wirelessly relays a sensor signal (i.e., a signal with a value corresponding with sensed pressure and thus with torque) to a controller.

Abstract: There are provided a device for detecting a rotation rate that prevents an eddy current from being generated in a housing member around a rotation rate sensor, and a device for detecting a rotation rate that prevents a decrease in the compressing efficiency of a fluid compressed by a rotor. A slit-shaped concave portion for preventing a generation of an eddy current is formed on the housing on both side of the rotation sensor. The rotation rate sensor generates a magnetic field by being supplied with a high-frequency alternating excitation current. The concave portion prevents an eddy current from being generated in the housing around the rotation rate sensor based on the magnetic field generated by the coil. The concave portion has a small capacity, and is formed along the flow of intake air. As a result, a decrease in the compression efficiency of the blades of the suction-side turbine can be prevented.

Abstract: A torque measurement of hydraulic installers for earth anchors, designed to sense hydraulic pressure and translate it into a torque output, through the use of transducers, regulator, and usually battery operated. By measuring the differential in supply pressure and return pressure transducers calibrating the same, thus furnishing a torque read-out, in foot pounds, of the amount of torque being applied by the installer when driving an earth anchor into the ground.

Abstract: A system for determining the weight of the occupant of a vehicle seat includes a hinge near the forward edge of the seat and a force sensor responsive to downward force at a point well to the rear of the hinge thereby indicating torque about the hinge. The system includes a microprocessor connected for receiving the output of the force sensor. The microprocessor may also receive outputs from an accelerometer responsive to vertical accelerations, a seat back recline angle sensor, a seat track position sensor, a seat belt tension sensor and an atmospheric pressure sensor. In a first embodiment the microprocessor determines the weight of the seat occupant from the outputs of the force sensor and the seat back recline sensor. In a second embodiment the microprocessor determines the weight of the seat occupant from the outputs of the force sensor, the seat back recline sensor and the seat track position sensor.

Abstract: An extensional rheometer comprises a drive shaft connected to an armature, wherein the armature is further connected to a torque shaft, and two rotatable drums are mounted in the armature. One end of a sample is connected to each drum, and the drums are rotated, stretching the sample until the sample breaks. The torque in the apparatus caused by the stretching of the sample is measured. Environmental control may be provided for testing samples under different conditions.
