Patent number: 11646487Abstract: This document describes a dual-antenna system for a video-recording doorbell and associated devices and systems. The described antenna system may be implemented on an elongated printed circuit board and can be used for wideband and ultra-wideband applications. For low-cost devices, the dual-antenna system may implement diversity antennas by including first and second substantially orthogonal antennas connected to a chipset configured for single-input single-output (SISO) functionality. The dual-antenna system described herein achieves high antenna isolation and efficiency without a decoupling structure between the first and second antennas. Further, the dual-antenna system achieves high isolation while in proximity to a battery (e.g., a battery within a housing of a battery-powered, video-recording doorbell) and a metal plate for mounting the device to a wall or other structure.Type: GrantFiled: April 6, 2022Date of Patent: May 9, 2023Assignee: Google LLCInventors: Huanyu Chen, Peter Joseph Bevelacqua, Emma Elizabeth Feshbach Bright

Patent number: 10334654Abstract: A wireless communication system is presented for multiple wireless technology coexistence in a mobile device. A method according to this application might include obtaining one or more transmit allocation parameters for a wireless transmission via a first radio technology at a first wireless processor and the preparing to receive wireless data via a second radio technology at a second wireless processor. Next, the exemplary method might request that the wireless transmission be deferred, followed by deciding whether to grant the deferral request based at least on the one or more transmit allocation parameters.Type: GrantFiled: March 26, 2018Date of Patent: June 25, 2019Assignee: Apple Inc.Inventors: William S. Burchill, Wen Zhao, Huanyu Chen, Zhaojun Cheng, Weiping Dou

Patent number: 10135476Abstract: An electronic device includes an antenna configured to receive a wireless transmission. The wireless transmission includes noise and data to be received. The electronic device includes a signal splitter that splits the wireless transmission into a first signal and a second signal. The electronic device includes a filter configured to filter the data to be received in the first signal. Furthermore, the electronic device includes merging circuitry configured to subtract the first signal from the second signal to reduce the noise in the second signal.Type: GrantFiled: February 1, 2016Date of Patent: November 20, 2018Assignee: APPLE INC.Inventors: Mohammad Reza Ghajar, Huanyu Chen, Robert S. Sorensen

Patent number: 9886066Abstract: A mobile wireless communications device may include a portable housing and wireless transceiver circuitry carried by the portable housing. The mobile wireless communications device may also include an antenna carried by the portable housing and coupled to the wireless transceiver circuitry, and a light source carried by the portable housing. The device may further include a keyboard assembly carried by the portable housing including a light guide coupled to the light source and having input key receiving openings therein, and a mask carried by the light guide and having input key receiving openings. The mask may include an electrically conductive layer positioned relative to the antenna to reduce a Specific Absorption Rate value for the mobile wireless communications device.Type: GrantFiled: July 2, 2010Date of Patent: February 6, 2018Assignee: BLACKBERRRY LIMITEDInventors: Meide Qiu, Huanyu Chen
