    Abstract: An in-cell touchscreen panel includes columns of transmit electrodes and rows of sensing electrodes, wherein each row of sensing electrodes comprises a first subset of sensing electrodes coupled to control circuitry via a first subset of receiving traces and a second subset of sensing electrodes coupled to the control circuitry via a second subset of receiving traces. To enable multi-touch functionality, the in-cell touchscreen panel operates in a scanning mode where capacitance is measured at each node where the sensing electrodes intersect the transmit electrodes. During the scanning mode, the control circuitry senses the first and second subsets of receiving traces while applying drive signals to pairs of transmit electrodes. After a drive signal has been applied to each of the transmit electrodes, each of the nodes are measured to detect a capacitance. This capacitance is indicative of a user touch on the in-cell touchscreen panel.

    Abstract: A micro-electro-mechanical system (MEMS) actuator circuit and method. The circuit includes a current mirror, a voltage divider having an interior contact and coupled between the mirror output and a potential, an operational amplifier having an input coupled to the interior contact and a switch having input/output contacts separately coupled to the amplifier output and the mirror input and having a switch control. The amplifier output can be coupled to a digital control circuit which can be coupled to the switch control contact and to a digital to analog circuit (DAC) which can be coupled to the digital control circuit and to another amplifier input. An enable signal at the switch control couples the switch input/output contacts together. The capacitance of a MEMS capacitor coupled to the mirror output is determined by measurement of time for the amplifier output to switch from one level to another following a change in DAC output potential.

    Abstract: A Yule-Walker based, low-complexity voice activity detector (VAD) is disclosed. An input signal is typically noisy speech (i.e., corrupted with, for example, babble noise). In one embodiment, a first initialization stage of the VAD computes an occurrence of a silent period within the input signal and the AR parameters. The VAD could accordingly compute a tentative adaptive threshold and output hypothesis H1 (which means speech is present) during this stage. During the second initialization stage, the VAD generally builds a database of associated values and computes the adaptive threshold accordingly. The second initialization stage could also output tentative VAD decisions based on the tentative threshold computed in the first initialization stage. Finally, the VAD periodically retrains or updates AR parameters, threshold values and/or the database and outputs VAD decisions accordingly.

    Abstract: A first input of a differential circuit is coupled to a coil tap for a first phase of a multi-phase brushless DC motor. The first phase is associated with an electrically floating coil. A second input of the differential circuit is coupled to a virtual center tap. A divider circuit is coupled between coil taps for other phases of the multi-phase brushless DC motor to define a virtual center tap. The other phases are phases actuated for motor operation when the first phase is electrically floating. The coil tap for the first phase is electrically isolated from the virtual center tap. The differential circuit performs a comparison of the voltage at the coil tap for the first phase to the voltage at the virtual center tap to generate a back EMF signal.

The determiner is configured to generate a representation of a difference between a first frequency at which a first signal is sampled and a second frequency at which a second signal is sampled, and the converter is configured to generate a second sample of the first signal at a second time in response to the representation and a first sample of the first signal at a first time. The adapter is configured to generate a sample of a modifier signal in response to the second sample of the first signal, and the modifier is configured to generate a modified sample of the second signal in response to a sample of the second signal and the sample of the modifier signal. For example, such an apparatus may be able to reduce the magnitude of an echo signal in a system having an audio pickup (e.g., a microphone) near an audio output (e.g., a speaker).
