Patent number: 11949272Abstract: A power supply circuit of a terminal device includes a voltage boost circuit, a battery chip, and a controller. The battery chip is configured to provide an output voltage of a battery for a load. An input end of the voltage boost circuit is connected to a positive electrode of the battery, and an output end of the voltage boost circuit is connected to the load. The output voltage of the battery is boosted when the temperature is relatively low or the output voltage of the battery is relatively low. In addition, when a relatively high pulse current occurs on the terminal and the output voltage of the voltage boost circuit is stepped down, both the battery chip and the voltage boost circuit is controlled to supply power to the load.Type: GrantFiled: July 27, 2018Date of Patent: April 2, 2024Assignee: HONOR DEVICE CO., LTD.Inventors: Yupeng Qiu, Ruiliang Li, Haibin Zhou, Fenwei Zhang

Publication number: 20220242371Abstract: Described are devices, systems and methods for real-time remote control of vehicles with high redundancy. In some embodiments, two copies of at least one control command are received using two different wireless communication protocols, and are compared. The at least one control command is executed when the two copies are in agreement, but is rejected when the two copies differ. In other embodiments, additional wireless communication protocols may exist to provide a redundant mode of communication when one of the two different wireless communication protocols are unavailable. In yet other embodiments, redundant GPS units may be used to determine availability of any of the communication protocols, and relevant control commands may be downloaded in advance to circumvent the lack of coverage.Type: ApplicationFiled: April 25, 2022Publication date: August 4, 2022Inventors: Xiaoling HAN, Charles A.
