Abstract: Systems and methods described herein provide techniques for analyzing gait and posture of a subject with respect to control data. The systems and methods, in some embodiments, processes video data, identifies keypoints representing body parts, determines metrics data at a stride level, and compares the metrics data to control data.

Abstract: A wave rolling assembly and a process for manufacturing a component for a vehicle using the wave rolling assembly is provided. The process includes conveying a metal coil through a first leveler to present a metal sheet, and conveying the metal sheet through a looping pit. The metal sheet travels from the looping pit to the wave rolling assembly for forming a plurality of waves along the side edges of the metal sheet. The wave rolling assembly stretches the metal sheet. The wave rolling assembly can include a die assembly or a roll forming apparatus. The metal sheet is then conveyed through a second leveler to flatten the metal sheet. The metal sheet is cut into blanks and formed into the finished component in a blanking press and die assembly. Less scrap is generated due to the reduced thickness along the edges and overall increased width of the blanks.

Abstract: A large aperture, high spatial resolution vibration and acoustic sensing device is provided. The sensor is capable of directional resolution of acoustic sources in gaseous, liquid, and solid media, and can be employed as a directional microphone or a directional hydrophone. The sensor can also be used as a high-resolution vibration displacement sensor. The device is formed of thin films comprising two electret layers and a compliant intermediate layer disposed therebetween. Conductive coatings disposed on the electret layers can be patterned and etched to provide a plurality of discrete sensing elements, forming a directional array. The sensor can be transparent, thereby allowing usage as a large area microphone disposed on top of a computer screen, video monitor, windows, or walls.
