  • Patent number: 11100733
    Abstract: A vehicle inspection device includes an inspection processing section and a communication processing section. The inspection processing section includes an inspection control section that generates a first communication request or a second communication request based on an inspection program, a communication request transmission buffer that stores the first communication request, and a transmission buffer for high-speed communication that stores the second communication request. The communication processing section transmits the first communication request to an ECU to be inspected and transmits the second communication request to an ECU on which writing is to be performed.

  • Patent number: 4357574
    Abstract: Loading apparatus for testing a power supply comprises an electronic load circuit, the electronic load circuit comprising an organically and systematically connected mode switching circuit capable switching from and to one another a constant resistance mode, a constant current mode and a slave mode. A load switching circuit is connected to the mode switching circuit and an error amplifier is adapted to input a voltage signal in each of the modes. A field effect transistor circuit is adapted to receive the output of the error amplifier as a gate control signal and has a drain terminal to which is fed the output from a power unit under test and further has a source terminal, the output of which is fed back as a comparison voltage signal to the error amplifier. A current measurement display circuit is branched to the source terminal of the field effect transistor circuit, and an overpower protection warning circuit is also branched to the source terminal.
