Abstract: An input apparatus includes a casing having an opening on one side in a first direction, a panel at least partly exposed through the opening and configured to receive a touch operation and a pressing operation, a holder supporting the panel and reciprocating together with the panel along with the pressing operation, a board in the casing, a sensor provided on the panel and configured to detect the touch operation, a pressure detecting portion configured to detect the pressing operation, and a connector that is provided on the board and connects to a signal cable extending from the sensor. The holder includes a temporary holding portion that holds the board in a state where the board is movable at least in the first direction relative to the holder. The casing includes a stopper that comes into contact with the board from the other side in the first direction.

Abstract: A communications relay apparatus for relaying communications between an electronic control unit (ECU) connected to the apparatus via an in-vehicle local area network (LAN) and an external device connected to the apparatus via a communication path different from the in-vehicle LAN. In the apparatus, a data transfer unit forwards relay data received from the ECU to the communication path and forwards relay data received from the external device to the in-vehicle LAN. But the data transfer unit is inhibited from forwarding reprogramming data for reprogramming the ECU received from the external device to the in-vehicle LAN. An authentication unit authenticates a vehicle user, and when the vehicle user is successfully authenticated, then permits the data transfer unit to forward the reprogramming data to the in-vehicle LAN.

Abstract: A delay system which has a communications device connected to a communications network and a relay device which is connected between the communications network ad an external device. The relay device is configured to divide data received from the external device into a plurality of data fragments each containing divided data, and send a sequence of messages, the messages corresponding to the respective divided data and dummy messages being included in the sequence of messages according to a communications rule. The communications device is configured to reconstitute the data from the external device on the basis of the message group from the relay device according to the communications rule.

Abstract: A duplexed bus type network in which a main transmission line and a stand-by transmission line are interconnected by a repeater (30), a changeover switch (40) or a two-way amplifier, a modem at each station is duplexed and connected to the main transmission line and the stand-by transmission line, and, upon trouble in one modem (11A), only the relevant station is switched over to the modem (21A) belonging to the stand-by transmission line. When the main transmission line is broken, all the stations are simultaneously switched over to the stand-by transmission line.
