Pulse indicator
First Claim
1. A portable pulse signaling device comprising a portable pressure sensor comprising a transducer and means for supporting said transducer in pressure sensitive contact with a body pulse area, means for discriminately adjusting the pressure of said transducer upon said pulse area whereby the periodic pulsing pressure therein upon said transducer is coverted into electrical signals significant of component pressure variations in said pulse, a portable amplifier electrical circuit means connected to and responsive to said pressure adjusted transducer to produce amplified electrical pulses, and a light emitter in said circuit responsive to the adjusted pressure visibly indicating said pulses by corresponding light flashes.

Abstract
A portable electrical device having both flashing light and/or sound transmitting means activated by a transducer so that the transducer or the entire assembly may be mounted in pressure sensitive contact with a pulsing area of a living body to convert pulses to visible light flashes or sound beats adjustable in pressure sensitive pickup to reflect and monitor the blood flow through the pulse.
