  • Patent number: 10976825
    Abstract: Embodiments described herein relate to methods and apparatuses for controlling an operation of a vibrational output system and/or an operation of an input sensor system, wherein the controller is for use in a device comprising the vibrational output system and the input sensor system. A controller comprises an input configured to receive an indication of activation or de-activation of an output of the vibrational output system; and an adjustment module configured to adjust the operation of the vibrational output system and/or the operation of the input sensor system based on the indication to reduce an interference expected to be caused by the output of the vibrational output system on the input sensory system.

  • Publication number: 20190261076
    Abstract: There is provided a USB audio accessory device, comprising: an audio transducer, configured to generate an audio transducer signal; interface circuitry, configured to receive analogue and digital representations of the audio transducer signal; and a USB-C connector for connecting to a USB host device, coupled to the interface circuitry. The interface circuitry is operable, in a first mode of operation, to output simultaneously the analogue representation of the audio transducer signal over a first pin of the USB-C connector, and the digital representation of the audio transducer signal over second and third pins of the USB-C connector.

  • Patent number: 8552893
    Abstract: A control system provides a control signal to a nonlinear plant that generates a response signal responsive to the control signal. The control system includes a detector that detects a predetermined value of a plant quantity, valley switching logic, coupled to the detector, to change a state of a plant switch when the plant quantity is minimized, and a pulse-width modulator, coupled to the valley switching logic, to generate a control signal that controls the plant switch. The valley switching logic includes a nonlinear delta-sigma modulator that compensates for an error in a plant response signal by adjusting the duration of an on-time of a plant switch to cause an average value of the plant response signal to converge toward a target signal value.

  • Patent number: 6535018
    Abstract: A level shifter 200 for shifting a logic high voltage of an input signal from a lower voltage to a higher voltage includes a latch 204 for storing a bit of data and having an output for driving a stored logic high bit at the higher voltage. A data node is coupled to a source of the higher voltage and an input of the latch. Voltage control circuitry 203 selectively gates the input signal received at the lower voltage with a bit of data stored in latch 204 and selectively pulls down the voltage at the data node in response.
