Abstract: One or more examples relate, generally, to a method for capacitive touch sensing that includes: performing first self-capacitance measurement of an electrode of a touch sensor while a driven shield-signal is provided to at least a portion of shielding of the electrode; determining a first touch sensing result at least partially responsive to determining that a value representing performing first self-capacitance measurement exceeds a first threshold value; performing second self-capacitance measurement of the electrode of the touch sensor while a ground signal is provided to at least the portion of shielding of the electrode; determining a second touch sensing result at least partially responsive to determining that a value representing performing second self-capacitance measurement exceeds a second threshold value, the second threshold value different from the first threshold value; and determining a touch result responsive to both the first touch sensing result and the second touch sensing result being indicative of a touch.

Abstract: A device is disclosed. In one or more examples, the device may include an antenna to receive a signal encoding timing information for one or more of positioning, navigation, and timing. The signal may include a pulse group comprising a number of ranging pulses and a number of data pulses subsequent to the number of ranging pulses. Respective ones of the number of data pulses may have a phase of either a positive-going phase or a negative-going phase. Data may be encoded using the either positive-going phases or negative-going phases of the data pulses. The device may include a processor to decode the data at least partially responsive to the phases of the respective ones of the number of data pulses.

Abstract: A method comprises generating a wireless power transmission signal in one or more transmit coils of a wireless power transmitter and, in a multi-frequency operation of the wireless power transmitter, controlling an operating frequency of the wireless power transmission signal to repeatedly switch between a fundamental frequency and one of a lower frequency and an upper frequency in an alternating manner. The lower frequency is offset from the fundamental frequency by a first offset. The upper frequency is offset from the fundamental frequency by a second offset. The second offset is different from the first offset. The first offset associated with the lower frequency and the second offset associated with the upper frequency are to ensure a transmit power in the multi-frequency operation is substantially the same as a transmit power at the fundamental frequency.

Abstract: An ideal diode bridge controller is provided that includes gate drivers to connect to transistors of a bridge rectifier in which the transistors are arranged as high-side transistors and low-side transistors. The gate drivers alternately switch the transistors to cause the bridge rectifier to convert an input voltage of either of two polarities to an output voltage of one of the two polarities. The gate drivers include low-side gate drivers for the low-side transistors, and respective ones of the low-side gate drivers include linear drive circuitry and digital drive circuitry. The linear drive circuitry drives a respective low-side transistor to switch on and off based on forward current through the respective low-side transistor. The digital drive circuitry detects a reverse current through the respective low-side transistor, and causes the respective low-side transistor to switch off in response to the reverse current.

Abstract: An apparatus is provided that includes a controlled voltage source and processing circuitry. The controlled voltage source connects to one or more light-emitting diode (LED) leads of a light-emitting diode (LED) controller that is in communication with a host. The processing circuitry selects a particular one of a plurality of predetermined voltages based on upstream information to be communicated to the host. The processing circuitry causes the controlled voltage source to impose the particular one of the plurality of predetermined voltages on the one or more LED leads, and thereby communicate the upstream information to the host via the LED controller.

Abstract: An apparatus is provided that includes one or more leads and processing circuitry. The one or more leads are to connect the apparatus to one or more light-emitting diode (LED) leads of an LED controller. The processing circuitry is to receive a pulse-width modulation (PWM) signal from the LED controller. The processing circuitry decodes the PWM signal to recover downstream information from the PWM signal, and performs an operation based on the downstream information.
