  • Publication number: 20190157898
    Abstract: A receiver device in an inductive energy transfer system can include a touch sensing device. If the input surface of the touch sensing device is touched, a transmitter device can periodically stop transferring energy to allow the touch sensing device to sense touch samples while inductive energy transfer is inactive. Additionally or alternatively, a transmitter device can produce an averaged duty cycle by transferring energy to the receiver device for one or more periods at a first duty cycle step and for one or more periods at different second first duty cycle step. Additionally or alternatively, a transmitter device can reduce a current level received by a DC-to-AC converter if the current received by the DC-to-AC converter equals or exceeds a threshold. Additionally or alternatively, a transmitter device can ping a receiver device and transfer energy only after a response signal is received from the receiver device.

  • Patent number: 9811204
    Abstract: A method of scanning a touch sensor panel while the touch sensor panel is coupled to a power adapter is disclosed. The power adapter can charge a battery of a device, but can also introduce or add noise during the process of charging the battery. To prevent adverse effects to the touch sensor panel, while the device is charging, the touch controller can time multiplex touch scan periods and inductive charging periods and can discard touch scans or touch images affected by the noise. Determining whether a touch scan is a bad touch scan can include performing a touch scan across the array of touch pixels and making a determination based on the scan profile. In some examples, the profile can be quantified using different metrics such as the shape, instantaneous slope of tail ends, a full-width half-maximum, and a monotonicity of the curve of the scan profile.

  • Patent number: 9391668
    Abstract: Reducing a power of a signal electromagnetically coupled from a PLC medium to a digital subscriber line (DSL) medium. The method involves transmitting a data signal over the PLC medium at a first average power level from one of a plurality of PLC transmitters coupled to the PLC medium, then measuring first noise associated with a first signal received at a DSL receiver coupled to the DSL communication medium caused at least in part by the data signal transmitted over the PLC medium at a second average power level from the one PLC transmitter, the second average power level different than the first average power level, followed by measuring second noise associated with a second signal received at the DSL receiver coupled to the DSL communication medium caused at least in part by the data signal transmission over the PLC medium at the second average power level.
