Publication number: 20240098920Abstract: An electronic device includes a base, a multi-stage sensor, a top cover, and a side cover. The multi-stage sensor is configured to sense a sensed area. The top cover includes a top-sensed element, and the top cover is detachably connected to a top side of the base, so that the top-sensed element can be selectively in or not in the sensed area. The side cover includes a side-sensed element, and the side cover is detachably adjacent to a front side of the base, so that the side-sensed element can be selectively in or not in the sensed area. In response to that only the top-sensed element is in the sensed area, the multi-stage sensor outputs a first signal. In response to that neither the top-sensed element nor the side-sensed element is in the sensed area, the multi-stage sensor outputs a second signal.Type: ApplicationFiled: November 2, 2022Publication date: March 21, 2024Inventors: Ching-Wen Hsiao, Chia-Hung Yen

Publication number: 20230417081Abstract: An electronic door lock with up-pushed locking is provided and includes a housing, a fixed latch assembly assembled in the housing, a linkage member and a first driving member. The first driving member is linked with an outer handle located outside a door. When a user lifts the outer handle, the first driving member is pulled to drive the linkage member, so that the linkage member abuts against a protruding rod located at a rear end of the fixed latch assembly, thereby pushing the fixed latch assembly to actuate, so that a fixed latch head of the fixed latch assembly protrudes out of the housing and the electronic door lock is locked. Accordingly, the problem that the user must use a key to lock the electronic door lock when the user is outside the door can be solved.Type: ApplicationFiled: May 18, 2023Publication date: December 28, 2023Applicant: TLHM CO., LTD.Inventors: Po-Yang CHEN, Chia-Hung YEN

Patent number: 7392529Abstract: An optical disc drive includes an electro-conductive chassis, a tray, a bezel and an electro-conductive sheet. Wherein, the electro-conductive chassis has an opening portion. The tray is disposed inside the electro-conductive chassis for carrying an information storage medium and can move into and from the electro-conductive chassis, and the bezel is disposed at a front edge of the tray. In addition, the electro-conductive sheet is disposed between the front edge of the tray and the bezel, and substantively covers the opening portion of the electro-conductive chassis. As the tray stays inside the electro-conductive chassis, the electro-conductive sheet is in contact with the electro-conductive chassis. Consequently, the electro-conductive sheet is able to reduce the electromagnetic interference (EMI) generated during the operating of the optical disc drive. Further, the electromagnetic wave leakage damaging human health is also prevented.Type: GrantFiled: June 29, 2005Date of Patent: June 24, 2008Assignee: Lite-On It CorporationInventor: Chia-Hung Yen
