Wireless Power System High Power
Issued US 20210143688A1
Abstract: A method of over-current protection in a wireless power receiver operating in a high-power mode includes digitally receiving an output current signal, generating an OC INT signal if the output current signal is greater than a current limit value, and if the OC INT signal is generated, transmitting Count A number of End Power Transfer (EPT) packets. If wireless power transmission has not stopped, transmitting Count C number of Control Error Packets (CEPs) with Value B. If wireless…
Abstract: A method of over-current protection in a wireless power receiver operating in a high-power mode includes digitally receiving an output current signal, generating an OC INT signal if the output current signal is greater than a current limit value, and if the OC INT signal is generated, transmitting Count A number of End Power Transfer (EPT) packets. If wireless power transmission has not stopped, transmitting Count C number of Control Error Packets (CEPs) with Value B. If wireless power transmission has not reduced such that the output current IL is below the current limit value, then enabling an LDO current limit circuit in a power block of the wireless power receiver. In a low-power mode, the receiver enables a hardware over-current circuit that generates an OC INT signal when the output current exceeds a current limit.

DISPLAY SCREEN POSITION SENSING USING INDUCTIVE SENSING
Issued 20220205816
Abstract: A method and a system may inductively determine a position of a display screen of a computing device. Associated processes may generate a magnetic field by providing an alternating current to a driver coil, and may generate a voltage at a sensor coil in response to the magnetic field. The system and method may additionally include determining a position of the display screen by executing an algorithm at a processor. An input to the algorithm may include voltage data associated with…
