  • Patent number: 8878559
    Abstract: An IC current measuring apparatus is provided between an IC and a substrate. The IC current measuring apparatus electrically connects each of a plurality of IC-facing terminals and a different one of a plurality of substrate-facing terminals. Especially, resistances are each inserted into a path between an IC terminal targeted for measurement and a substrate terminal corresponding thereto. Furthermore, the IC current measuring apparatus is provided with terminals each used to measure a voltage between both ends of an inserted resistance corresponding thereto. Accordingly, a measurer who measures current flowing through an IC-facing terminal can measure the current flowing through the IC-facing terminal by providing the IC current measuring apparatus between the IC targeted for measurement and the substrate and measuring a voltage between both ends of an inserted resistance corresponding to the IC terminal through which current he/she wishes to measure flows.

  • Patent number: 8879027
    Abstract: On a liquid crystal panel, plural areas whose number is larger than that of temperature sensors are defined. In a memory, temperature relation information representing a relation between an output value of a temperature sensor and a temperature of each of the plural areas is stored. A controller acquires the output value of the temperature sensor and estimates, based on the temperature relation information and the acquired output value, the temperature of each of the plural areas. According to this configuration, the temperature of each of the plural areas defined on the liquid crystal panel can be obtained with a small number of temperature sensors.

  • Patent number: 8806314
    Abstract: A detection signal transmitting unit 123 of a first component 110 transmits a plurality of detection signals having different frequency spectrums to a second component 210. Upon receiving the detection signals, a detection signal returning unit 233 of the second component 210 returns, as return signals, respective signal waveforms of the received detection signals to the first component 110. A detection signal judging unit 126 of the first component 110 judges authenticity of the received return signals based on the transmitted detection signals. When the judging unit judges that the received return signals are not authentic, a tamper-resistance control unit 127 adds a restriction to the communication performed between the first component 110 and the second component 210.

  • Patent number: 8767137
    Abstract: In a liquid crystal display device, the reduction of power consumption is realized by reddening a backlight while maintaining a white balance. An aperture ratio of a red subpixel and an aperture ratio of a blue subpixel are set such that, in a state where an aperture ratio of a green subpixel in each pixel of a liquid crystal panel is fixed to a desired value, white brightness efficiency takes a maximum value which is set based on a balance between light emission efficiency which is increased corresponding to lowering of a color temperature of the backlight and transmissivity of the pixel which is decreased corresponding to the increase of the aperture ratio of the blue subpixel.

  • Patent number: 8675083
    Abstract: One array antenna including three induction coils is formed on an application integrated circuit of a fixed housing. Eight array antennas, each of which is arranged in a manner similar to that of the array antennas of the application integrated circuit, are formed at intervals of 45 degrees around a rotation axis on an imaging process integrated circuit of a movable housing. A controller selects one of the eight array antennas of the imaging process integrated circuit so that a magnitude of a difference between a rotation angle of a movable housing and a rotation angle of the movable housing becomes equal to or smaller than 22.5 degrees based on the rotation angle of the movable housing, and controls a stepping motor so that a selected array antenna opposes to the array antenna on the application integrated circuit.
