Force effect spatial-resolution detection device for use during e.g. clamping protection of electric window lift, has signal processing device determining position of effect along waveguide based on time difference between time points

摘要

The device (100) has a waveguide (110) whose dielectric includes elastic material. A time-domain reflectometry system (120) is coupled to the waveguide. A signal processing device (130) is coupled to the reflectometry system. The signal processing device is designed to determine a position (104) of a force effect (102) along the waveguide based on a time difference (106) between a time point (182) of coupling of a signal from the reflectometry system into the waveguide and a time point (184) of receiving of reflection of the signal. Independent claims are also included for the following: (1) a method for spatial-resolution detection of a force effect (2) a computer program having a set of instructions to perform a method for spatial-resolution detection of a force effect.
