Abstract: A tactile or haptic guidance device incorporates a LIDAR assembly and servo motor assembly or linear actuators to provide tactile feedback to the user. The LIDAR assembly determines obstacles in the path of the user and the micro-controller uses the LIDAR data to send a signal to the servo motor assembly or linear actuators, which will cause translational or rotational movement along one or more axes with appropriate amounts of force to provide tactile feedback to the user about objects in their path.

Abstract: The present invention provides a polishing endpoint detection system, for use with a polishing apparatus, a method of determining a polishing endpoint of a surface located on a semiconductor wafer, and a method of manufacturing an integrated circuit on a semiconductor wafer. In one embodiment, the polishing endpoint detection system includes a carrier head having a polishing platen associated therewith. Also, the detection system includes a signal emitter located adjacent one of the carrier head or polishing platen. The signal emitter is configured to generate an emitted signal capable of traveling through an object to be polished. In addition, the detection system includes a signal receiver located adjacent another of the carrier head or polishing platen. The signal receiver is configured to receive the emitted signal from which a change in a signal intensity of the emitted signal can be determined.
