摘要： 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.

摘要： 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.

摘要： A drive signal generating unit generates a drive signal used to alternately deliver a positive current and a negative current to a coil with a nonconducting period inserted between conducting periods. A driver unit generates a drive current in response to the drive signal generated by the drive signal generating unit and supplies the drive current to a coil. An induced voltage detector detects an induced voltage occurring in the coil during the nonconducting period. A zero-cross detecting unit detects the zero cross of the induced voltage detected by the induced voltage detector. The drive signal generator estimates the eigen frequency of the linear vibration motor based on a detected position of the zero cross, and the frequency of the drive signal is brought close to the estimated eigen frequency.
