Abstract: A device for attachment to a linear force transmission medium such as a wire or rod includes a flexure body having axially aligned tubular extensions on opposite ends that can receive and be crimped to the medium to create a continuous path for tensile force transmission. The flexure carries strain gages on top and bottom planar surface portions that are connected into a bridge circuit that responds to stress in the flexure body. Leads are protected against disconnection from solder pads by wrapping the leads and a carrier for them around the exterior circumferential surface of a jacket that fits on and around the flexure body. An FPC plug embodiment is disclosed.

Abstract: A torque detection device of a rear frame of an electrically assisted bicycle includes two displacement detection units and a processing unit. The displacement detection units are installed at upper and lower fork arms of the rear frame respectively for detecting and converting displacement into force. Through mechanical analysis and mathematical operations, the processing unit processes signals obtained by the displacement detection units to remove any force perpendicular to a road surface and obtain a rider's treading torque while pedaling a pedal crank module. The displacement detection units are mounted onto the upper and lower fork arms without requiring any rotary joint. The displacement detection units are displacement detection devices applying different physical and chemical methods, such as strain gauges, piezoelectric sensors, electromagnetic sensors, capacitive sensors, or optical sensors. The torque detection device features simple manufacture and device, and the advantage of measuring the treading torque accurately.

Abstract: There is provided a measuring device (dial gauge) capable of performing measurement with a desired measuring force regardless of the posture of the measuring device.
A dial gauge in an exemplary embodiment of the present invention includes a measuring force adjustment unit provided to a body case and capable of moving and being positioned and fixed in a direction substantially parallel to a moving direction of a spindle.
A biasing means has one end directly or indirectly engaged with the spindle and the other end directly or indirectly engaged with the measuring force adjustment unit, and biases the spindle toward a tip end.
The measuring force adjustment unit includes an external thread portion and a connection supporting member having one end screwed with the external thread portion and the other end coupled to the biasing means. The connection supporting member is screw-fed by rotationally operating the external thread portion in such a manner that a position of the connection supporting member is changed and fixed.-

Abstract: The invention relates to a load detection unit having a spring-elastic load carrier assembly for receiving the load (10) and a sensor (3) for the deformation of the load carrier assembly, which occurs under the load (10) that is to be detected, wherein a deformation transmission unit (6) is operatively arranged between the load carrier assembly and the sensor (3). A method, in which additionally a deformation transmission unit is used, is thus provided, which during operation picks up the deformation of the load carrier assembly and transmits it to the sensor as a changed force/path load.

Abstract: The invention relates to a method for monitoring the condition of a continuous element (44) moving in a fiber web or paper finishing machine, said monitoring being performed with a rotating machine element (41), which is equipped with a sensor assembly (24) that measures force or pressure and against which the continuous element moves. In the method, the machine element is made to rotate against the continuous element, a measurement signal (25) is generated between the machine element and the continuous element with the sensor assembly, and a cross-directional profile (21) of force or pressure generated between the machine element and the continuous element is formed from the measurement signal. Said moving continuous element is a fabric (32, 33) installed in a fabric run (22, 23) traveling via the machine element. In the method, the fabric is additionally installed in a fabric run, wherein it moves via said machine element equipped with a sensor assembly, a reference profile (35) is formed for the cross-directional profile after installing the fabric in the fabric run, the cross-directional profile formed from the measurement signal and representing force or pressure generated between the machine element and the fabric is compared with the reference profile, and information (37) is produced from the comparison for monitoring the condition of the fabric. The invention also relates to a corresponding system and a computer program product.
