Filed: 1990-11-29
Abstract: PURPOSE:To miniaturize a control circuit by releasing a can gear from its locking by means of an electromagnetic plunger and returning a head base to a stop position when a power source voltage becomes lower than a prescribed value. CONSTITUTION:When it is detected that the power source voltage is lowered to the prescribed value in a play mode, the electromagnetic plunger 113 is energized to release its positional regulation to a trigger lever 104, and the can gear 84 is released from its locking.

Abstract: PROBLEM TO BE SOLVED: To provide a method for accurately detecting the eye closing time while an eyelid is blinking by using the closed eyes curve based on the video signal. SOLUTION: The transitional change sampled by a CCD camera according to blinks for the observation pattern including at least that of eyelids is taken as the voltage change to create a waveform with the voltage axis vs the time axis.

Then, low-frequency components are removed from the sampled waveform. Furthermore, the lower envelope components of the resultant waveform are removed to obtain another waveform stabilized relative to a base line, for which the base line is extended in the direction of the time axis at a reference position relative to the voltage axis. After that, the time axis corresponding to the stabilized waveform relative to the base line, which exceeds the predetermined threshold voltage and eye closing time is measured to detect the eye closing time of eyelids.
