Publication number: 20240080054Abstract: To more accurately determine whether a first electronic device is disposed in a second electronic device, which may be an enclosure for the first electronic device, the first electronic device may determine Voltage Standing Wave Ratio (VSWR) values at its transceiver, and determine whether it is moving and/or disposed in the second electronic device based on the VSWR values. If the first electronic device determines the it is disposed in the second electronic device, then the first electronic device may perform radio frequency coexistence actions, such as backing off (e.g., reducing) radio power or deactivating its radio to avoid radio frequency coexistence issues with the second electronic device.Type: ApplicationFiled: December 5, 2022Publication date: March 7, 2024Inventors: Mohammed W Mokhtar, Alireza Pourghorban Saghati, Rafik M.

Patent number: 11831061Abstract: An electronic device may include one or more radios and one or more antennas. Radio-frequency transmission lines may couple a radio to a corresponding antenna. To more efficiently form a radio-frequency transmission line, the radio-frequency transmission line may be formed from interconnected conductive traces distributed between a plurality of printed circuits. By integrating transmission line structures onto printed circuits that also serve other functions, the device can require less space to implement a radio-frequency transmission line. While one or more of these printed circuits may individually be unsuitable to implement a radio-frequency transmission line with a particular impedance, the composite impedance of these transmission line structures across the printed circuits, when properly configured, may provide a radio-frequency transmission line with the particular impedance.Type: GrantFiled: August 31, 2022Date of Patent: November 28, 2023Assignee: Apple Inc.Inventors: Alireza Pourghorban Saghati, Mohammed W.

Patent number: 11522390Abstract: The disclosed wireless transmitter estimates a client location in space and transmits power in the form of electromagnetic (EM) waves to that location. In response to receiving the power, a client sends a power request signal. In some implementations, the power request signal includes a request that the wireless transmitter transmit more power to the client. In response to the power request signal, the wireless transmitter can modify the power transmitted to the client to increase/decrease the amount of power the client is receiving. For example, the wireless transmitter can modify the emitted EM waves to increase coherent addition or decrease coherent addition at the location of the client to increase the amount of power the client receives. In some implementations, the wireless transmitter modifies the phase distribution of EM waves to increase the amount of power a client receives.Type: GrantFiled: November 13, 2020Date of Patent: December 6, 2022Assignee: Ossia Inc.Inventors: Hatem Ibrahim Zeine, Alireza Pourghorban Saghati, Siamak Ebadi
