Patent number: 11967832Abstract: Systems and methods for wireless power transfer systems are described. A controller of a device can communicate with a power device by a first modulation mode. The controller can detect a failure condition between the controller and the power device. The controller can, in response to the detection of the failure condition, communicate with the power device by a second modulation mode. The first modulation mode can include capacitive modulation and the second modulation mode can include resistive modulation.Type: GrantFiled: September 15, 2022Date of Patent: April 23, 2024Assignee: RENESAS ELECTRONICS AMERICA INC.Inventors: Jiangjian Huang, Hulong Zeng

Patent number: 11881732Abstract: An apparatus, a method and a non-transitory computer-readable storage medium storing a program for controlling power receiving operation. The apparatus includes a controller configured to compare a frequency of an electric current generated by a voltage induced in a power receiving circuit by a magnetic field generated by a power transmitting apparatus, against a frequency threshold to determine whether the frequency is equal to or below the frequency threshold, and in response to determining that the frequency is equal to or below the frequency threshold, control a communications circuit to communicate a control command message instructing the power transmitting apparatus to modify a power charge signal used to provide the magnetic field in a manner for protecting the apparatus.Type: GrantFiled: January 13, 2021Date of Patent: January 23, 2024Assignee: Renesas Electronics America Inc.Inventors: Jiangjian Huang, Hulong Zeng

Patent number: 11881911Abstract: Systems and apparatuses for wireless power transfer system are described. A receiver may send an amplitude shift key (ASK) signal to a transmitter. The transmitter may receive the ASK signal from the receiver. The transmitter may perform a demodulation on the ASK signal. The transmitter may, in response to a failure to demodulate the ASK signal, encode a notification of failure in a frequency shift key (FSK) signal. The transmitter may transmit the FSK signal to the receiver. The receiver may receive the FSK signal. The receiver may perform a function to resolve the failure to demodulate the ASK signal.Type: GrantFiled: September 15, 2021Date of Patent: January 23, 2024Assignee: Renesas Electronics America Inc.Inventors: Jiangjian Huang, Hulong Zeng, Gopinath Akkinepally, Amit Dharmendra Bavisi
