Abstract: Sensing arrangements for measuring force or torque by transmitting light on a reflective region and measuring how the reflected light is received, including a sensor arrangement that uses a non-symmetric reflective region and a sensor arrangement that uses multiple arrangements of at least three light sensors, where the at least three light sensors are arranged such that they are not co-linear.

Abstract: The present invention relates, in part, to systems for characterizing force (e.g., friction, wear, and/or torque). In one embodiment, the system allows for wear testing of samples in a high throughput manner. In another embodiment, the system allows for torque sensing in a non-contact manner.

Abstract: An encoder includes an optical scale that has a phase difference plate, a light source section that irradiates the phase difference plate with light, and a light receiving section that receives the light from the phase difference plate, and outputs a signal corresponding to a received light intensity. The light emitted from the light source section is linearly polarized, and the light receiving section outputs a signal corresponding to a polarization state of the light from the phase difference plate.

Abstract: A device is for the optoelectronic measurement of torque with a first component (2), and a second component (3), it being possible for the first component (2) to be connected to a drive element and the second component (3) to be connected to a drive element, or vice versa. A first encoding element that is arranged on the first component (2). A second encoding element is arranged on the second component (3). A first light barrier (6) detects the rotational movement of the first encoding element. A second light barrier (7) detects the rotational movement of the second encoding element. An electronic evaluation unit (8) detects and evaluates signals originating from the first light barrier (6) and second light barrier (7), with at least one elastic element that is deformable according to a torque acting upon it being provided between the first (2) and the second component (3). When the torque changes, a change in the angle-of-rotation position of the components (2, 3) in relation to one another can be identified and the torque calculated on that basis.

Abstract: The present disclosure presents a visuo-haptic sensor, which is based on a passive, deformable element whose deformation is observed by a camera. In particular, the improved simplified sensor may determine the force and/or torque applied to a point of the sensor in multiple spatial dimensions.
