  • Publication number: 20210175745
    Abstract: A wireless power device is presented that avoids transmit conflicts. The device can include a rectifier circuit coupled to a coil; a transmit driver coupled to the rectifier circuit; a transmit detect circuit configured to detect receipt of transmitted wireless power at the coil; and a controller coupled to the transmit driver and the transmit detect circuit, the controller receiving a signal from the transmit detect circuit and providing an alert of the presence of the transmitted wireless power, the controller activating the transmit driver to transmit wireless power in absence of the signal. The wireless device can determine an operating mode and in a transmit mode determine presence of a received power. If received power is detected an alert can be provided and an off state initiated. If transmit power is not detected the transmit driver can be activated.

  • Patent number: 10630109
    Abstract: A wireless power system includes a receiver. The receiver may include a rectifier coupled to a receiver coil to receive power. The receiver may include a detector coupled to the rectifier to receive a monitor signal from the rectifier. The detector may provide a range signal indicating whether the monitor signal is outside a predetermined range. The receiver further includes an oscillation determiner coupled to the detector to receive the range signal. The oscillation determiner may determine that the rectifier is in an oscillation mode or is not in an oscillation mode. In some embodiments a communication unit is coupled to the oscillation determiner. The oscillation determiner may communicate a power adjustment signal and may request increased power through the communication unit.

  • Publication number: 20090322700
    Abstract: Resistive touchscreen system has substrate and coversheet with first and second conductive coatings. The substrate and coversheet are positioned proximate each other such that the first conductive coating faces the second conductive coating. The substrate and coversheet are electrically disconnected with respect to each other in the absence of a touch. First set of electrodes is formed on the substrate for establishing voltage gradients in first direction. Second set of electrodes is formed on the coversheet for establishing voltage gradients in second direction wherein the first and second directions are different. Controller biases the first and second sets of electrodes in first and second cycles and senses a bias load resistance associated with at least one of the sets of electrodes. The bias load resistance has a reference value associated with no touch. A decrease in the bias load resistance relative to the reference value indicates two simultaneous touches.
