Abstract: In a first aspect of the invention, it is claimed a computer-implemented method for assisting the movement of a visually impaired user by means of a wearable device 1, comprising the following steps: S1—Acquiring data from the environment of the visually impaired user S2—Fusing the acquired data, creating, repeatedly updating of a Live Map S3—Determining, repeatedly updating and storing, of at least one navigation path together with associated navigation guiding instructions for the visually impaired user to navigate from the current position of the visually impaired user to a point of interest, repeatedly selecting one preferred navigation path from the at least one navigation path, and repeatedly sending to the visually impaired user the preferred navigation path, together with associated navigation guiding instructions.

Abstract: A torque measuring device for measuring the torque in a shaft that is subjected to torsion and has two axially arranged shaft sections. A first shaft section functions as a driveshaft and a second shaft section functions as an output shaft and is connected to a load-dependent sensor. An annular light-sensitive element is attached to the first shaft section an annular light-emitting element is arranged on the second shaft section. A measuring body with a load-dependent sensor is disposed between the shaft sections. The annular light-sensitive element is electrically conductively connected to the annular light-emitting element via the load-dependent sensor. A lamp element and a photoelectric element are arranged outside the shaft. Light from the lamp element is directed towards the annular light-sensitive element, and the light emitted by the light-emitting element is received by the photoelectric element and supplied to an evaluation unit.
