Patent number: 9478503Abstract: 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.Type: GrantFiled: February 28, 2013Date of Patent: October 25, 2016Assignees: TOHOKU UNIVERSITY, KABUSHIKI KAISHA TOYOTA CHUO-KENKYUSHO, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Mitsutoshi Makihata, Masayoshi Esashi, Shuji Tanaka, Masanori Muroyama, Hirofumi Funabashi, Yutaka Nonomura, Yoshiyuki Hata, Hitoshi Yamada, Takahiro Nakayama, Ui Yamaguchi

Patent number: 9215089Abstract: 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.Type: GrantFiled: October 14, 2009Date of Patent: December 15, 2015Assignees: TOHOKU UNIVERSITY, KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHO, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masanori Muroyama, Masayoshi Esashi, Shuji Tanaka, Sakae Matsuzaki, Mitsutoshi Makihata, Yutaka Nonomura, Motohiro Fujiyoshi, Takahiro Nakayama, Ui Yamaguchi, Hitoshi Yamada
