Abstract: A fraudulent diagnostic machine detection apparatus capable of preventing the occurrence of fraudulent processing due to a fraudulent diagnostic machine being connected in parallel with a legitimate diagnostic machine is a fraudulent diagnostic machine detection apparatus comprising node ECUs of a diagnosis target connected to a communication line and a gateway connected between the communication line and a diagnostic machine connection coupler, wherein the gateway detects an electrical circuit change caused by a pin connection of the diagnostic machine connection coupler being branched and the plurality of diagnostic machines being connected in parallel.

Abstract: An endoscope system includes an endoscope and a processor device. The processor device functions as an abnormality detection unit, an abnormality information generation unit, and an abnormality information management unit. The abnormality detection unit detects an abnormality of the endoscope by using information detected by an image sensor of the endoscope. The abnormality information generation unit generates abnormality information including sensor information detected by the image sensor at a time of abnormality detection and in a predetermined period before and after the abnormality detection and operating information of the endoscope. The abnormality information management unit stores the abnormality information in a memory.

Abstract: A program management device includes a communication unit that communicates with an external device that is present outside a vehicle, a first storage unit having an irrespective program storage area where an irrespective program that is irrespective of control of the vehicle is stored, a second storage unit provided independently of the first storage unit, and an update processing unit configured to store in the second storage unit an irrespective update program received by the communication unit, the irrespective update program being used to update the irrespective program. The update processing unit executes processing of storing, in the second storage unit, the irrespective program stored in the irrespective program storage area, and subsequently executes processing of storing the irrespective program in the irrespective program storage area based on the irrespective update program stored in the second storage unit.

Abstract: A position information providing system includes at least one message transmitter and an authentication server synchronous in time with each other. The message transmitter includes generation means for generating an authentication code depending on time and a specific code and transmission means for transmitting a message.

Abstract: A fuel tank system includes an ECU receiving an open signal Sa of a fuel supply SW. The ECU has a main control unit controlling a power unit of a vehicle, a main relay control circuit turning off a main relay when IGSW for causing the power unit to start or stop is turned off, SOAK time measurement circuit measuring an input time and no input time, the input time being a time during which the open signal Sa is continuously inputted to the ECU while the IGSW is off, the no input time being a time during which the open signal Sa is not inputted to the ECU while the IGSW is off with the fuel supply SW on, and a failure determination unit determining that the fuel supply SW has an abnormality when SOAK time is longer than a failure determination time.

Abstract: For an enhanced coupling efficiency between a light source and an optical fiber bundle: the optical fiber bundle is made up by a dense bundle of optical fibers, with an integrated portion composed of fusion-integrated distal ends of the bundled optical fibers, and the integrated portion has, in a longitudinal sectional plane along a center axis of the optical fiber bundle, a lateral side thereof formed, in a shape of arc radially outwardly convex with respect to a straight line interconnecting an end point at a front end face side of the integrated portion and an end point at a rear end side thereof, to locate at a radially inner side with respect to an extension toward the integrated portion of a line constituting an outline of a portion else than the integrated portion of the optical fiber bundle.
