  • Patent number: 11993226
    Abstract: An on-vehicle control device includes a transmission unit transmitting to a mobile device a response request signal requesting a response in response to operation of instructing a start of a driving source causing a vehicle to drive. An authentication unit authenticates the mobile device and performs start control of the driving source depending on success or failure of authentication by the authentication unit. A determination unit determines a presence or an absence of unauthorized authentication for the authentication unit. A detection unit detects an authorized occupant for the vehicle. A start prohibition unit prohibits the start of the driving source when the determination unit determines that unauthorized authentication is present for the authentication unit. A start permission unit permits the start of the driving source regardless of determination by the determination unit when the detection unit detects the occupant.

  • Publication number: 20240170945
    Abstract: A power supply circuit protection device has a PWM control circuit and a voltage sensor that detects an input voltage to be supplied to a step-up power supply circuit. When it is sensed that the input voltage detected by the voltage sensor satisfies a predetermined voltage condition, the PWM control circuit sets the duty cycle of a PWM signal to a value smaller than a duty cycle setting at a normal time. On the basis that the load of the step-up power supply circuit correlates to the input voltage, the input voltage to the step-up power supply circuit is detected by the voltage sensor. This enables the load of the step-up power supply circuit to be more accurately detected. Therefore, when the duty cycle of the PWM signal is set to a value smaller than at the normal time, the load of the step-up power supply circuit is reduced.

  • Patent number: 11983362
    Abstract: A first detection signal creation unit has detection nodes connected to detection electrodes in one-to-one correspondence. The first detection signal creation unit supplies charge from each detection node through a second wire to the relevant detection electrode so that a voltage at the relevant detection node vibrates according to an alternating-current voltage, and creates first detection signals matching the supplied charge. First filters are provided in first paths, each of which branches from an alternating-current output node to a first wire. A phase difference signal creation unit creates a phase difference signal matching the phase difference between the alternating-current voltage and one of the first detection signals.

  • Patent number: 11979120
    Abstract: Amplifying circuitry configured such that when a detection circuit detects an abnormal state in which the level of signals input to a main amplifying circuit exceeds a normal range, a control circuit sets the state of integration of signals in the integration circuit to a default state. When the detection circuit detects the abnormal state and then detects that an operating state returns to a normal state in which the level of signals input to the main amplifying circuit is included in the normal range, the control circuit cancels the setting of the default state in the integration circuit.

  • Publication number: 20240137698
    Abstract: A controller calculates individual parameters, including nonlinear parameters of a speaker model, based on a measured displacement of a vibration system of a speaker. A sound generator outputs an audio signal, and an output flattening filter adjusts gains of individual bands of an audio signal so that a frequency characteristic of a volume of sound output by the speaker is flattened in accordance with a speaker model obtained by linearizing calculated parameters and outputs a resultant audio signal. A nonlinear inverse filter corrects the resultant audio signal by signal processing adapted to the gains of the output flattening filter so that the nonlinear distortion of the speaker is suppressed in accordance with the speaker model including the nonlinear parameters and outputs the corrected audio signal as an output audio signal to the speaker via an amplifier.
