Abstract: The present application discloses implementations that relate to devices and techniques for sensing position, force, and torque. Devices described herein may include a light emitter, photodetectors, and a curved reflector. The light emitter may project light onto the curved reflector, which may reflect portions of that projected light onto one or more of the photodetectors. Based on the illuminances measured at the photodetectors, the position of the curved reflector may be determined. In some implementations, the curved reflector and the light emitter may be elastically coupled via one or more spring elements; in these implementations, a force vector representing a magnitude and direction of a force applied against the curved reflector may be determined based on the position of the curved reflector.

Abstract: A device for detecting a mechanical state of a machine element rotates about an axis, such as a shaft is formed with an actuator disposed on the machine element so as to be axially movable, an arrangement for converting a torsion of the machine element into an axial displacement of the actuator and a sensor disposed so as to be stationary relative to the machine element for detecting the axial displacement of the actuator. A mark is assigned to the actuator for detection by the sensor in order to detect the axial displacement of the actuator. A speed (n) of the machine element can be determined from the number of marks that are detected per unit of time.

Abstract: A sensor assembly comprises a base plate and a sensor member displaceable relative to the base plate. A spring arrangement operates in first and second stages in response to displacement of the sensor member relative to the base plate. Different resolutions of force and torque measurements are associated with the first and second stages. A light sensitive transducer senses displacement of the sensor member relative to the base plate and generates corresponding output signals. A collimator directs a plurality of light beams onto the light sensitive transducer so that the light beams strike different pixels of the light sensitive transducer to sense displacement of the sensor member relative to the base plate.
