There are: a communication sheet that propagates electromagnetic wave; a wireless communication part arranged close to the communication sheet, and stores predetermined information, and wirelessly transmits the predetermined information to the communication sheet; a shield part that shields a radio signal wirelessly transmitted from the wireless communication part; an operation part that enables or disables wireless communication between the communication sheet and the wireless communication part; and a discrimination part that discriminates contents of operation by the operation part based on the predetermined information wirelessly transmitted by the wireless communication part. According to an operation by said operation part to disable the wireless communication between said communication sheet and the wireless communication part, said shield part shields the radio signal from the wireless communication part.

Switch device

Provided is an in-vehicle power supply apparatus which supplies power to both a high-power load such as an actuator, and the CPU for controlling the high-lower load, and which is capable of preventing reduction in voltage of the CPU even when voltage of the in-vehicle power supply is momentarily reduced due to power consumption of the high-power load, and which include an auxiliary power supply having its capacity reduced so as to enable reduction of the size of the power supply apparatus. The in-vehicle power supply apparatus for supplying a power to both a power load, and a CPU for controlling the power load comprises: a first distribution line for distributing, to the power load, the power supplied from an in-vehicle power supply through a bus; a second distribution line for distributing, to the CPU, the power supplied from the in-vehicle power supply through the bus; an auxiliary power supply, connected to the second distribution line, for supplying the power to the CPU when a voltage is reduced in the bus; and a backward flow prevention section for preventing a charge stored in the auxiliary power supply from flowing into the bus.

In-vehicle power supply apparatus

A data communication network system which enables an intended unit to determine a start point for a transmission schedule in communication is provided. In a data communication network system in which a plurality of electronic control units perform network communication through a communication line based on a time triggered communication protocol, a control section for previously putting the communication line in a communication inhibited state, and canceling the communication inhibited state at a predetermined time is included, and a predetermined one unit among the plurality of electronic control units transmits a message for synchronization, in a communication time, with the other units thereamong immediately after the communication inhibited state is cancelled.

Data communication network system

The power supply system includes a generator, a transformer circuit, and a battery. The generator generates electric power of a first voltage. The transformer circuit boosts the electric power of the first voltage to a second voltage. The battery is connected, via the transformer circuit, to the generator and stores electric power of the second voltage obtained by the boosting by the transformer circuit. At least one of actuators is connected on the generator side of the transformer circuit, so as to be supplied with the electric power of the first voltage.

Power supply system

A holding structure of an electronic component includes a first resin mold formed by resin insert molding with a terminal. The first resin mold possesses a positioning portion for positioning the electronic component to be electrically connected to the terminal. The holding structure includes a second resin mold formed by resin insert molding with the terminal and surrounding the first resin mold and the electronic component. The electronic component has been positioned by the first resin mold and has been electrically connected to the terminal.
