Publication number: 20240413666Abstract: An example computing device includes a wireless communication device, such as a wireless wide area network (WWAN) communication device, that communicates in a first band of electromagnetic radiation, and a wireless charging system that wirelessly charges a peripheral device using a second band of electromagnetic radiation. The wireless charging system operating in the first band may introduce harmonic noise that negatively impacts communication in the second band. Accordingly, in various examples, the system operates to adjust the charge rate used by the wireless charging system based on a function of the charge state of the peripheral device and a received signal strength indicator (RSSI) value of a signal received by the wireless communication device. In some instances, the wireless charging rate of the peripheral device may be disabled or reduced when the RSSI value of the signal received by the wireless communication device is below a threshold value.Type: ApplicationFiled: November 30, 2021Publication date: December 12, 2024Applicant: Hewlett-Packard Development Company, L.P.Inventors: HUAI-YUNG YEN, RUEI-TING LIN, CHENG-FANG LIN, REN-HAO CHEN, LO-CHUN TUNG

Patent number: 12119887Abstract: The present disclosure provides intelligent radio frequency interference mitigation in a computing platform. The computing platform includes a processor, a memory, a system clock and a wireless network interface. The system clock can be controlled so that the processor and/or the memory may operate at a slow frequency or a fast frequency. The wireless network may operate on a radio channel that experiences radio frequency interference at the fast frequency. The system clock may be intelligently controlled to select the slow frequency to reduce radio frequency interference to prioritize execution of a network application, or to select the fast frequency to increase processor speed and prioritize execution of a local application.Type: GrantFiled: September 22, 2022Date of Patent: October 15, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ruei-Ting Lin, Cheng-Fang Lin, Huai-yung Yen, Ren-Hao Chen, Lo-Chun Tung

Patent number: 11388682Abstract: In one example, a device may include a transceiver to receive a signal at a first transmit power from an access point via a wireless network connection. The first transmit power may be based on a feedback received signal strength indicator (RSSI) value.
