  • Publication number: 20130342222
    Abstract: In a rotary input apparatus, a stationary ground electrode, a first stationary sensing electrode, and a second stationary sensing electrode are formed on a stationary facing surface of a stationary plate. The first stationary sensing electrode includes first facing portions and a first connecting portion electrically connecting the first facing portions, and the second stationary sensing electrode includes second facing portions and a second connecting portion electrically connecting the second facing portions. Each of the first facing portions has a different phase from that of the corresponding one of the second facing portions in a rotation direction. When a rotary electrode, which is provided on a rotary portion, rotates, an encoded signal of a first phase is obtained between the first stationary sensing electrode and the ground potential, and an encoded signal of a second phase is obtained between the second stationary sensing electrode and the ground potential.

  • Patent number: 8354606
    Abstract: A push switch includes an operating member, a holding member, a detecting electrode including a plate-shaped spring, a conductive coil spring, and a wiring substrate. The operating member includes a top portion. The rear surface of the top portion and the holding member define a storage space. The detecting electrode, received in the storage space, includes a detecting portion in resilient contact with the top portion, a base in resilient contact with the coil spring, and a height adjusting portion coupling the detecting portion to the base. The amount of compression of the detecting electrode is defined depending on the height of the storage space. The detecting portion detects a change in capacitance caused when the operation surface is touched by a human body and a detection signal indicating the change is output to the wiring substrate through the height adjusting portion, the base, and the coil spring.

  • Patent number: 8352986
    Abstract: A picture display system having two display devices and a base device for supplying picture signals to one of the display devices and capable of having bidirectional communication with the other display device is disclosed. The picture display system (1) is made up by a mobile display device (100), a base device (200) and a large format display device (300). The base device (200) sends picture signals to the display device (100) and to the large format display device (300). On a display image surface of the mobile display device (100), there is provided a touch panel for detecting the contact position contacted by a user for displaying a remote-control panel RP accepting an operating input from the user on the display image surface. An operating signal conforming to a display item of the remote-control panel RP, displayed at a contact position, detected by the touch panel, is generated and transmitted by wireless communication to the base device (200).
