  • Patent number: 10747704
    Abstract: An electronic unit includes a USB host and a USB device. After the USB host and the USB device are connected to each other by a USB cable, a signal requesting for a connection permission is transmitted from the USB device to the USB host, and the USB host determines whether to permit a connection based on the signal. The electronic unit further includes a power supply configured to supply power to the USB device, and an additional GND pattern different from a GND pattern of the USB cable is electrically connected to a GND of the USB port of at least one of the USB host and the USB device. An area of the additional GND pattern is 2000 mm2 or more.

  • Patent number: 9478503
    Abstract: An integrated device with high insulation tolerance is provided. A groove having an inclined side surface is provided between adjacent devices. When a side where an electronic circuit or MEMS device is mounted is a front surface, the groove becomes narrower from the front surface to a back surface because of the inclined surface. A mold material (insulating material) is disposed inside the groove, so that the plurality of devices are mechanically joined together, being electrically insulated from one another. A line member that establishes an electrical conduction between the adjacent devices is formed to lie along the side surface and the bottom surface of the groove. To lead the line out to the backside, the bottom surface of the groove has a hole, so that the line member is exposed to the backside from the hole.

  • Patent number: 9215089
    Abstract: A touch sensor system includes buses, a plurality of touch sensor devices disposed on the buses, and an information integrating device that is connected to all the buses and integrates information from the touch sensor device. The touch sensor device includes a sensor unit and a signal processing unit that transmits a sensor data signal generated by processing an analog sensor signal to the information integrating device through the bus. The signal processing unit includes a digital converting unit, a threshold evaluating unit that gives a start permission of the signal process when a sensor value exceeds a preset threshold, an ID adding unit that adds a transmitter identification number to the sensor signal, and a data transmitting unit that outputs the sensor data signal to a signal line of the bus. Fast responses are made possible without increasing the amount of data and host processing load while including many touch sensor elements.
