  • Patent number: 8751962
    Abstract: In regards to the conventional technology for performing operational inputs by referring a GUI and by means of a touch sensor, there exists a problem in which the relationship of correspondence between on-screen locations of selection items on a GUI and touchpad locations cannot be accurately grasped. Moreover, cases in which a touch panel equipped with an information display function instead of a touch sensor is used cause problems in that the cost thereof or power consumed thereby can be relatively high, etc. In order to solve the problems described as above, the present invention provides a remote control that selects an icon on a GUI as a target of operation using a touch sensor, and which is characterized by a configuration that allows a user to easily identify the relationship of correspondence by brightening of a touch sensor on a touchpad corresponding to icon arrangement on a GUI.

  • Patent number: 8605856
    Abstract: A radiation image capturing device is provided with plural pixels, a detection unit and a control unit. The pixels are each provided with a sensor portion and a switching element that reads out charges generated at the sensor portion and outputs the charges to a signal line. The detection unit detects the start of irradiation if electronic signals according to the charges satisfy a pre-specified condition for irradiation detection. After the start of irradiation of radiation is detected, the control unit acquires electronic signals corresponding to the charges and determines whether the acquired electronic signals include an electronic signal caused by noise. If the electronic signal caused by noise is included, the control unit controls a reporting unit so as to report this.
