Abstract: A semiconductor module includes a substrate, a semiconductor package disposed to the substrate, a housing to which the substrate is fixed, and a Y capacitor. A front-surface wiring in the substrate includes a front-surface ground wiring electrically connected to the housing, and a front-surface main wiring connected to a rear-surface wiring that is connected to the semiconductor package. The Y capacitor is disposed on a front surface of the substrate at a position facing the semiconductor package and between the front-surface ground wiring and the front-surface main wiring. The semiconductor package and the Y capacitor are disposed in such a manner that a direction of electric current flowing in the semiconductor package and a direction of electric current flowing in the Y capacitor are opposite to each other.

Abstract: A semiconductor module includes a resin molded part encapsulating a semiconductor chip, a first terminal having a plate shape, and a second terminal having a plate shape. The first terminal and the second terminal are disposed on top of the other in a thickness direction. The first terminal is exposed from a first surface of the resin molded part, and the second terminal is projected from a second surface of the resin molded part to an outside of the resin molded part, the second surface being different from the first surface from which the first terminal is exposed.

Abstract: A shunt-based current sensor executes redundancy detection of a load current flowing through a load by using a shunt resistor. The shunt-based current sensor includes a reference resistor, a current excitation circuit, at least two voltage measurement circuits and a signal processing circuit. The reference resistor is connected to the shunt resistor in series. The current excitation circuit generates an AC excitation current and supply the AC excitation current to the shunt resistor and the reference resistor. At least two voltage measurement circuits measure a voltage across the shunt resistor. A signal processing circuit executes signal processing based on respective measurement voltages of the at least two voltage measurement circuits, and is operated in the load current redundancy detection mode or a shunt resistance measurement mode.

Abstract: A vehicle position estimating device includes a coordinates obtaining unit, a map information obtaining unit, a surrounding information obtaining unit, a vehicle position estimating unit, a relative position estimating unit, and a correcting unit. The coordinates obtaining unit obtains coordinates of a first vehicle. The map information obtaining unit obtains map information including the coordinates obtained by the coordinates obtaining unit. The surrounding information obtaining unit obtains surrounding information indicating a reference around the first vehicle that is detected by a surrounding sensor. The vehicle position estimating unit estimates a first vehicle position using the map information and the surrounding information. The relative position estimating unit estimates a relative position of a second vehicle around the first vehicle with respect to the first vehicle. The correcting unit corrects the first vehicle position using the relative position and a second vehicle position obtained from the second vehicle.

Abstract: A movement amount estimation device includes an external movement amount acquisition unit configured to acquire an external movement amount as a movement amount of a moving body using external information, an internal movement amount acquisition unit configured to acquire an internal movement amount as the movement amount of the moving body using internal information, and a movement amount estimation unit configured to estimate the movement amount of the moving body using at least one of the external movement amount and the internal movement amount. The movement amount estimation unit is further configured to acquire a difference between the external movement amount and the internal movement amount, and determine whether to use the external movement amount or the internal movement amount to estimate the movement amount depending on whether the difference is equal to or less than a predetermined threshold value.

Abstract: An ultrasonic generator has a speaker element having a first resonance frequency and a speaker element having a second resonance frequency. The first resonance frequency and the second resonance frequency are adjacent resonance frequencies in the speaker. The distance between the elements is set so that the sound from the first speaker element and the sound from the second speaker element have a predetermined relationship at a target position. The target position is two or more positions on the object located in the target space. A predetermined relationship is a relationship in which a sound from the first speaker element and a sound from the second speaker element strengthen each other at an intermediate frequency between the first resonance frequency and the second resonance frequency.
