Abstract: Provided is a head photic stimulation device including: a brain wave amplifier which subjects the subject brain waves acquired using a brain wave sensor to A/D conversion and amplification; a control signal generation circuit which, based on an output signal from the brain wave amplifier, generates a control signal for controlling LED driving; and a light irradiation unit which is driven based on an output from the control signal generation circuit, and which includes an LED for irradiating a head. The control signal generation circuit includes a band-pass filter for filtering an input signal, a DSP (signal processing) unit for controlling a signal that has passed through the band-pass filter, and a light irradiation output unit using a near-infrared LED for irradiating the head. The DSP unit has a feedback function for matching a phase of a PWM output for controlling the light irradiation output unit, in synchronism with the subject brain waves.

Abstract: The apparatus for assessing the risk of cerebrovascular diseases comprises a sensor part 1, a circuit part 2, a computation part 3 and an output part 4, where the circuit part 2 is a functional part for driving the sensor part 1 and transmitting a signal detected at the sensor part 1 to the computation part 3 and comprises a transmission circuit 21, a first receiving circuit 22, a second receiving circuit 23 and the like. The transmission circuit 21 is in connection with a transmission device 111 and a transmission device 121, for driving these devices to generate a continuous wave. A rate wave form computation part 31 is in connection with the first receiving circuit 22 and the second receiving circuit 23 to obtain the frequency of the reflected continuous wave as detected with the receiving units 112 and 122. Comparing the frequency with the frequency from the transmission circuit 21, the variation of the frequency is detected. Based on these values, blood flow rate “v” can be determined.
