Publication number: 20210137439Abstract: Multiple circuits in a computing device can share one or more conductive elements. The use of the conductive element can vary by circuit, such as an antenna radiator for a radio frequency (RF) circuit or an electrode for an electrocardiography (ECG) circuit. The circuitry sharing a conductive element can utilize signals obtained over different frequency ranges. Those ranges can be used to select decoupling circuitry, or elements, that can enable the respective circuits to obtain signals over a respective frequency range, excluding signals over one or more other frequency ranges corresponding to other circuitry sharing the circuit. Such an approach allows for concurrent independent operation of the circuitry sharing a conductive element.Type: ApplicationFiled: October 16, 2020Publication date: May 13, 2021Inventors: Yonghua Wei, Faton Tefiku, Kevin Li, Man-Chi Liu, Lindsey Michelle Sunden, Peter W. Richards, Dennis Jacob McCray, Christos Kinezos Ioannou, Kyung Nim Noh

Patent number: 10637129Abstract: A wearable computing device can include a monopole-excited slot antenna formed by a gap between a housing (such as a highly conductive housing) and a bracket (such as a highly conductive bracket) within the highly conductive housing and by a back cavity between the highly conductive bracket and the PCB. The antenna configuration can include a monopole antenna electrically coupled to a printed circuit board and a slot antenna that is excited through coupled electromagnetic fields. The highly conductive bracket is positioned near a display window of the device, mostly below and partially enclosing a battery. The highly conductive bracket is positioned above the printed circuit board. This configuration allows for a relatively small dead band in the display window, a larger battery, compact and mechanically simple configuration, and superior water resistance.Type: GrantFiled: January 22, 2019Date of Patent: April 28, 2020Assignee: Fitbit, Inc.Inventors: Yonghua Wei, Kevin Li, Patrick James Markan, Allen Yu-Li Wang, Teemu Taneli Raafael Kaiponen, Christos Kinezos Ioannou
