Abstract: A gait assistance slab is provided. The gait assistance slab includes a body that includes an outer surface. The gait assistance slab further includes a plurality of sensors disposed inside the body. The gait assistance slab further includes a plurality of actuators disposed inside the body. The gait assistance slab further includes circuitry communicatively coupled to the plurality of sensors and the plurality of actuators. The circuitry detects a presence of a person on the outer surface based on an electric signal acquired from one of the plurality of sensors. The circuitry determines a level of actuation of one of the plurality of actuators based on the detected presence of the person and the acquired electric signal. The circuitry further controls, based on the determined level of actuation, the one of the plurality of actuators to assist gait of the person on the outer surface.

Abstract: A system and a method for projection of a pattern of light on a work-piece are provided. The system includes an optical sensor, circuitry, and a projection device. The circuitry controls the optical sensor to capture a first plurality of light signals that bounces off from a surface of a work-piece and estimates a plurality of surface features of the work-piece based on the captured first plurality of light signals. The circuitry determines projection information for a pattern of light to be projected onto the surface of the work-piece based on the estimated plurality of surface features. Based on the determined projection information, the circuitry controls the projection device to project the pattern of light onto the surface of the work-piece.

Abstract: A system for providing safety assistance in a vehicle. The system includes a helmet and a first plurality of sensors in the helmet. The system further includes control circuitry that captures a first plurality of signals from the first plurality of sensors in the helmet. The first plurality of signals indicates first motion information corresponding to the helmet. The control circuitry further controls one of an inflation element or a hardening element disposed in a wearable garment based on a determination that the first motion information corresponding to the helmet exceeds a first predefined threshold.

Abstract: This invention pertains to electronic/optoelectronic devices with reduced extended defects and to a method for making it. The device includes a substrate, a semiconductor active material deposited on said substrate, and electrical contacts. The semiconductor active material defines raised structures having atomically smooth surfaces. The method includes the steps of depositing a dielectric thin film mask material on a semiconductor substrate surface; patterning the mask material to form openings therein extending to the substrate surface; growing active material in the openings; removing the mask material to form the device with reduced extended defect density; and depositing electrical contacts on the device.
