Patent number: 11936411Abstract: Systems, methods, and apparatuses, including electronic devices and computer-readable storage media, for adaptively switching wireless connections between antennas of a wearable electronic device and a host electronic device. One device includes a wearable electronic device with a first and second housing, each housing including two or more antennas. The wearable electronic device is configured to establish and monitor a wireless cross-link between two antennas in different housings, or between antennas in one housing and antennas of a host electronic device. The wearable electronic device can monitor the integrity of the wireless cross-link, and establish an updated cross-link in response to the wireless cross-link not meeting a predetermined integrity threshold. The wearable electronic device can monitor a wireless cross-head link between housings of a wearable electronic device at the same time as a wireless cross-body link between the wearable electronic device and the host electronic device.Type: GrantFiled: November 18, 2022Date of Patent: March 19, 2024Assignee: Google LLCInventors: Vijay Asrani, Jiang Zhu, Nan Xu

Publication number: 20220181769Abstract: The present disclosure provides a metal structure, or antenna radiator, for an accessory that is configured to function as both an antenna and an input control. The device may be a wearable device with a first surface shaped to be in contact with the human body and a second surface shaped to be exposed when the device is being worn. The antenna radiator may be located internally within the housing of the device and coupled to a printed circuit board (“PCB”). The PCB may be located between the antenna radiator and the surface of the housing such that the PCB may shield the antenna radiator from antenna loss due to the human body. An electric field may extend between the PCB and the antenna radiator. The fringe electric field may improve cross-head and cross-body connectivity between the accessory and another device.Type: ApplicationFiled: July 15, 2020Publication date: June 9, 2022Inventors: Nan Xu, Vijay Asrani, Jiang Zhu

Patent number: 8483632Abstract: Embodiments include systems and methods for controlling radiation of radio frequency (RF) energy by a wireless communication device that includes a transmitter, an antenna, a vector field sensor, and a processing system. The transmitter produces an analog RF signal, and the antenna radiates the analog RF signal into an environment. The vector field sensor senses an intensity of a vector field resulting from the analog RF signal radiated by at least the antenna (and possibly other portions of the device). The processing system determines whether a value representing the intensity is greater than a first threshold, and when the value is greater than the first threshold, the processing system causes the radiated RF energy produced by the wireless communication device to be decreased.Type: GrantFiled: November 13, 2009Date of Patent: July 9, 2013Assignee: Motorola Mobility LLCInventors: Vijay Asrani, Matthew Biggerstaff, Greg Black, Arthur Christopher Leyh, Pete Nanni, Adrian Napoles, Ben White
