Abstract: Sensors are provided for detecting brain waves of a user, and a band-pass filter is provided for extracting a particular brain waves including an .alpha. wave included in a detected brain wave. The band-pass filter comprises a first band-pass filter having a narrow pass band, and a second band-pass filter having a wide pass band. One of the first and second band-pass filters is selected, and a stimulation signal is produced in dependency on an .alpha. wave extracted by a selected band-pass filter. In accordance with the stimulation signal, a stimulation light is emitted to the user in order to induce the user to relax or sleeping state.

Abstract: An information reproducing apparatus applied to a psychological game machine which can evaluate the deep mental state of human, avoiding monotonous progress of a game. A plurality of image and audio information have previously been stored on a recording medium such that at least one of the plurality of image and audio information stored on the recording medium is selected for reproduction based on external operations and physiological changes in the body.

Abstract: A driving mental condition detecting apparatus for detecting a deterioration state of driving mental conditions such as sleepiness, fatigue, and impatience occurring in a driver on the basis of physiological data detected from the driver and road travel data of a vehicle derived from a navigation system, thereby generating an alarm.

Abstract: A system for producing an oscillating signal includes a phase-locked loop including a control voltage producing circuit. The control voltage producing circuit is provided for producing a plurality of predetermined control voltages, with each of the predetermined control voltages corresponding to a desired frequency. A plurality of memories are provided in the phase-locked loop for storing the predetermined control voltages. A control device is connected to the plurality of memories for storing the predetermined control voltages in the memories in a state where the phase-locked loop is closed, and for deriving at least one of the predetermined control voltages stored in the memories in a state where the phase-locked loop is opened. A voltage-control oscillator is provided in the phase-locked loop to be operated by the predetermined control voltage derived from one of the memories for producing the oscillating signal having a desired frequency dependent upon the desired voltage.

Abstract: A system for producing a jamming signal to be inserted in a band of CATV has a voltage producing circuit for producing a control voltage corresponding to the band, and a first voltage-controlled oscillator for producing a first jamming signal having a frequency dependent on the control voltage, and capacitors for storing the control voltage. A second jamming signal is produced by a second jamming signal producing circuit from the charged stored control voltage. A CPU is provided for controlling the production of the first and second jamming signals.

Abstract: A video signal optical transmission system reproduces and transmits video and audio signals from an optical disk as pulsed FM signals which are converted to optical signals prior to transmission. No additional frequency modulation is required prior to transmission. With this transmission system, special demodulation circuitry no longer is required, so that existing demodulation circuitry on the receiving side can be used.

Abstract: A video signal coordination system which enables selective transmission of video signals from a plurality of sources with simpler digital switching systems which require fewer cross points and thus reduce the cost of the overall system. For each of a plurality of video source groups, an associated digital switching system is provided, so that the overall number of switching systems is equal to the number of video source groups. Queuing problems are avoided by having some duplication of video sources across various ones of the video source groups.
