  • Publication number: 20250226604
    Abstract: A connector device includes a circuit board and a connector mounted on the circuit board. The connector includes an outer conductor capable of electrical conduction with a shield layer of a shielded wire, a sub-board, an IC mounted on the sub-board, and heat transfer portions (a heat dissipation sheet, a metal plate, an outer conductor, and sub-ground circuits) that transfer heat of the IC to the shield layer. With this configuration, since the heat of the IC can be transferred to the shield layer of the shielded wire via the heat transfer portions, the heat of the IC can be readily released.

  • Patent number: 11914082
    Abstract: A ranging device includes transducers, a transmission circuit, a reception circuit, a transfer data generation circuit, and a transfer circuit. The transmission circuit causes the transducers to transmit transmission waves. The reception circuit outputs a received signal obtained by digitizing a reflected wave of the transmission wave with a sampling frequency equal to or more than a frequency of the transmission wave. The generation circuit separates, into a target period and a non-target period, time-series received signals. The target period is a period in which a wave height is equal to or more than a threshold. The non-target period is a period in which a wave height is less than the threshold. The generation circuit performs thinning-out processing on received signals in the non-target period and generates waveform information indicating a waveform received by the transducer. The transfer circuit outputs the waveform information.

  • Publication number: 20210284033
    Abstract: Corresponding to a case in which the existence and the type of foreign matter that obstructs power transmission around a power transmission unit are detected when a battery mounted on a vehicle is charged by a non-contact method, a power transmission amount of the power transmission unit is reduced, and the reduction amount is controlled according to a difference in the type of the foreign matter. A notification for urging the removal of the foreign matter is intentionally omitted when it is predicted that the charging of the battery mounted on the vehicle is completed before a use start time of the vehicle or before a predetermined period elapses from the use start time of the vehicle even if the power transmission amount of the power transmission unit is reduced.
