Abstract: A range finding device is provided that is capable of selecting between range finding based on a phase difference and range finding based on a frequency spectrum depending on conditions of a signal exchanged with a communication device. The range finding device includes: a first range finder to perform range finding by a first range finding method based on a phase difference of a signal received from a transmitter and output a first distance; a second range finder to perform range finder based on a second range finding method based on a frequency spectrum of the signal received from the transmitter and output a second distance; and a selector to select the first distance or the second distance based on a frequency spectrum or phase linearity of the signal received from the transmitter.

Abstract: An audio signal processing device generates an output signal by alleviating a noise component in an input signal including both a sound component to be heard and the noise component. The audio signal processing device includes: a composite sound output part to output a composite sound signal; an adaptive filter to receive as an input the composite sound signal output from the composite sound output part; and a subtraction part to output an output sound signal by subtracting an output signal of the adaptive filter from an input sound signal. The adaptive filter performs adaptation operation assuming that the output sound signal from the subtraction part is an error. The composite sound signal from the composite sound output part is formed with pure tones of multiple frequencies extracted from a frequency band that is to be cancelled and that includes a frequency band of the alleviated noise component.

Abstract: A door opener for a vehicle includes a housing; an operation lever attached to the housing such as to be rotatable around a rotation shaft between an initial position and a terminal position; a first switch configured to generate a control signal; a connector connected to a second switch that mechanically opens a door of a vehicle; a tactile sensation generating mechanism; and an elastic body that returns the operation lever. The first and second switch are turned off when a rotation angle of the operation lever is in a first angle range. When the rotation angle is in a second angle range, the first switch is turned on, a tactile sensation is generated by the tactile sensation generating mechanism, and the second switch remains turned off. When the rotation angle is in a third angle range, the second switch is turned on.
