Publication number: 20240141939Abstract: A chassis quick release device includes a housing including a base with a connected sliding channel and accommodating space therein and a cover assembled with the base, a locking block linearly movably set in the accommodating space, and an operating handle having a rod body positioned on the sliding channel and a grip assembled with the rod body. The rod body has a cylindrical joint that corresponds to the grip and has a shaft groove defined therein. The grip is provided with a sleeve corresponding to the cylindrical joint and defining therein an accommodating cavity. Moving the operating handle in the direction of the housing causes the locking block to slide out from the accommodating space to form a locked state. Pulling the operating handle away from the housing causes the locking block to move linearly in a second direction to form an unlocked state.Type: ApplicationFiled: January 2, 2024Publication date: May 2, 2024Inventors: Ying-Chih TSENG, Ming-De WU, Ching-Kai CHANG

Patent number: 11955705Abstract: A multi-input multi-output antenna system capable of being disposed in an electronic device and the electronic device including the antenna system have a low-frequency antenna assembly and a high-frequency antenna assembly. The low-frequency antenna assembly includes multiple low-frequency antennas that are spaced apart from each other by a distance. The high-frequency antenna assembly includes multiple high-frequency antennas that are spaced apart from each other by a distance. One of the high-frequency antennas is structured as a low-profile dish antenna and is located between the low-frequency antennas, so that the antenna system has smaller volume and height, and better isolation and radiation patterns.Type: GrantFiled: June 13, 2022Date of Patent: April 9, 2024Assignee: Alpha Networks Inc.Inventors: De-Chang Su, Chih Jen Cheng
