Patent number: 11668378Abstract: A linear transmission device includes a screw, a moving member, a return element, and a sensor. The moving member is set in the screw to form a load path therebetween. The return element is set in the moving member and has a return path connected to the load path. The return path and the load path constitute a circulating path for balls to run. The moving member has an internal thread with an ineffective thread section. The moving member has a receiving groove adjacent to the ineffective thread section. The sensor is embedded in the receiving groove of the moving member without affecting the operation of the balls. Thus, the linear transmission device of the present invention can solve the problem of the sensor protruding from the moving member, so that the configuration of the surrounding space and the stroke of the moving member will not be affected.Type: GrantFiled: November 16, 2021Date of Patent: June 6, 2023Assignee: HIWIN TECHNOLOGIES CORP.Inventors: Szu-Wei Yu, Chih-Hsiang Chen, Meng-Ying Lin

Patent number: 11307406Abstract: A Cascaded Mirror Array optical scanning system applies an array of reflectors, with each reflector (called array reflector for convenience) movable between discretized angular positions and independently switched by digitized electrical signals, to process a light beam by cascaded reflections to generate desired deflection angle of the beam. The precision of the discretized angular positions of each array reflector is maintained by a support structure, which supports the reflector while allowing it to rotate or tilt, and a set of positioning limiting structure, which limits the allowable angular position of the array reflector between a finite number of angular positions corresponding to the discretized angular positions.Type: GrantFiled: October 31, 2019Date of Patent: April 19, 2022Assignee: NATIONAL TSING HUA UNIVERSITYInventors: Che-Chih Tsao, Chih-Hsiang Chen
