  • Patent number: 7556604
    Abstract: A cognitive capacity measuring device utilizes an image display unit for displaying different kinds of images that have been degraded from an original photographic object. A subject can provide an input when he/she discerns the photographic object in the degraded image. Recognition time periods are recorded and matched with predetermined challenge level data parameters to calculate a cognitive capacity of the subject. A statistically significant number of test subjects provide recognition times relative to a specific degraded image so that a normal distribution from a frequency distribution of the number of subjects in relationship to a logarithm of the recognition times can be determined. The normal distribution along with the challenge level parameters can provide an indication of the subject's cognitive capabilities.

  • Publication number: 20090051488
    Abstract: A technique for achieving a risk-free keyless entry system for vehicles at low costs is disclosed. The keyless entry system includes a transmitter responsive to an operation of an operation unit for transmitting a signal indicative of to-be-sent information toward an on-board device at a prespecified communication rate. The on-board device is attached to inside of a vehicle, for receiving electrical waves as sent from the transmitter and for outputting a control signal used to drive electric motors of door lock actuators and/or a motor of slide door actuator. By changing the communication rate of the signal being sent from the transmitter, the door lock control signal is made shorter in arrival distance than the slide door control signal.

  • Publication number: 20080303754
    Abstract: In performing a display in accordance with a video signal, a display signal for inspection is supplied to a pixel within a predetermined inspected row to operate an EL element therein and to thereby detect a current that flows through the EL element. The current detection data is stored in a volatile primary memory. In accordance with data obtained in this manner, a variation correcting section sequentially corrects data signals to be supplied to the respective pixel. At the time of turning on power, the variation correcting section performs the correction using the current detection data saved in a secondary memory. With this arrangement, it is possible to execute display variation correction from immediately after turning on power, and it is also possible to execute real-time correction.

  • Publication number: 20080079702
    Abstract: An integrated driving apparatus having an elongated shape mounted at a peripheral portion of a display apparatus comprising a display section on a panel substrate comprises a logic section, a power supply circuit section, and a D/A converter. The logic section comprises a digital display data processor and a timing signal generator which generates a timing control signal necessary for the display apparatus and the D/A converter converts digital display data obtained by the digital display data processor into analog data. The power supply circuit section generates a power supply voltage used in the display apparatus using a signal from the timing signal generator. The power supply circuit section and the D/A converter are provided on left and right of the logic section with the logic section therebetween so that the power supply circuit section and the D/A converter are placed adjacent to the logic section along a long side direction of the elongated shape of the integrated driving apparatus.

  • Patent number: 7310057
    Abstract: A serial-parallel conversion circuit in which power consumption is reduced is provided by using a latch clock generation circuit including multiple latch signal generation circuits which outputs a latch signal with a period of an integer multiple of that of a system clock signal. Here, the latch signal generation circuit includes a gate circuit which receives a control signal and a feedback signal, and outputs, according to a combination of the received control signal and feedback signal, a latch signal obtained by inverting a pulse corresponding to one clock of the system clock signal, and an output synchronization circuit which holds the latch signal output from the gate circuit and at the same time outputs the latch signal as a control signal supplied to a gate circuit of a latch signal generation circuit of the succeeding stage and a feedback signal supplied to the gate circuit of the self stage.
