US11467672B2 Context-sensitive control of radar-based gesture-recognition
This document describes techniques and systems for radar-based gesture-recognition with context-sensitive gating and other context-sensitive controls. Sensor data from a proximity sensor (108) and/or a movement sensor (108) produces a context of a user equipment (102). The techniques and systems enable the user equipment (102) to recognize contexts when a radar system (104) can be unreliable and should not be used for gesture-recognition, enabling the user equipment (102) to automatically disable or “gate” the output from the radar system (104) according to context. The user equipment (102) prevents the radar system (104) from transitioning to a high-power state (1910) to perform gesture-recognition in contexts where radar data detected by the radar system (104) is likely due to unintentional input. By so doing, the techniques conserve power, improve accuracy, or reduce latency relative to many common techniques and systems for radar-based gesture-recognition.

The sliding element rests against a planar contact area of the sliding surface so that the hydraulic piston is secured against twisting and is axially displaceable by a rotation of the spindle or the spindle nut.
US11466760B2 Actuator systems for solar trackers
A solar tracking system includes a solar array, support beams that support the solar array, a torque tube coupled to the support beams, a base that rotatably supports the torque tube, and an articulation system that rotates the torque tube relative to the base. The articulation system includes an outer tube, a screw rod, and a nut and/or inner tube that rotates and translates along a length of the screw rod as the screw rod rotates. The interior portion of the outer tube includes helical grooves and the exterior portion of the nut or inner tube includes ridges or rollers that mate with the helical grooves, which cause the nut and/or inner tube to rotate as the nut and/or inner tube is translated along a length of the screw rod when the screw rod is rotated by the motor.
US11466758B2 Belt-driven conical pulley transmission for a motor vehicle
A belt-driven conical pulley transmission includes a first pulley sheave pair arranged on the first shaft, a second pulley sheave pair arranged on the second shaft, a belt means, a first slide rail, and a second slide rail. Each pulley sheave pair includes a first conical pully displaceable along a respective shaft axis and a second conical pulley fixed along the respective axis. The belt means is displaceable in a radial direction along respective contact faces of the pulley sheave pairs from an inner position to an outer position. The belt means includes a traction strand extending through an intermediate space between the first pulley sheave pair and the second pulley sheave pair, and a thrust strand extending through the intermediate space. The first slide rail is guides the traction strand and the second slide rail is designed different from the first slide rail and guides the thrust strand.
US11466756B2 System for a belt tensioner
Systems are provided for a belt tensioner. In one example, the belt tensioner comprises a fluid chamber divided into a first portion and a second portion via a dividing wall. An eccentric housing, which defines the fluid chamber, rotates relative to the dividing wall based on a spring force and a belt force.
US11466754B2 Chain structure of bicycles
The present invention is a chain structure of bicycles, which comprises a plurality of rollers, a plurality of chain sheets and a plurality of chain rollers. Wherein the rollers define a mounting space. Each chain sheet comprises a chain body, a first pivot joint part extending from one end of chain body and to be arranged in the mounting space, a second pivot joint part horizontally extending from the other end of chain body, the second pivot joint part is installed on the roller with the first pivot joint part, wherein the first pivot joint part is in a horizontal position different from chain body, the first pivot joint part defines a rotation space for placing the second pivot joint part of another chain sheet, so that the first pivot joint part and second pivot joint part can rotate a preset angle in the rotation space. When the chain sheets are combined with rollers respectively, the chain bodies remain on the same plane, the chain roller penetrates the second pivot joint part and the first pivot joint part respectively for connecting the roller to the chain sheets on both sides of roller. Thereby, the chain is thinned and the weight is reduced, the tensile strength is increased by thickening the chain sheet.
US11466753B2 Ratcheting strap adjuster
A ratcheting strap adjuster comprising a bracket, a webbing plate, and one or more captive members. The webbing plate is rotatably coupled to the bracket. Each of the one or more captive members is moveable between an engaged position and a disengaged position, wherein the one or more captive members restrict rotation of the webbing plate in one direction when the one or more captive members are in the engaged position and allow rotation of the webbing plate in the one direction and in an opposite second direction when the one or more captive members are in the disengaged position.
