Arterial pulse rate monitor and stress warning device
First Claim
1. A portable blood pulse rate monitor and stress warning device for warning of imminent heart trouble to the user of the device, said device comprising:
- case means for housing components of the device, said case means including a case member having wall means defining a dual purpose combined resonator-amplifier chamber in the form of;
a shallow horn or hopper-shaped pulse-amplifying chamber having a closed-off large end and a smaller oppositely disposed narrowed and elongated open end;
a membrane stretched across and overlaying said latter chamber at its large end to close off same, said membrane adapted to lay against a given pulse area and to amplify the attendant pulse thereat;
a resonator in the form of a thin linear reed supported by and within said case member in a manner extending medially across said chamber adjacent said narrowed open end thereof;
said resonator reed being of a material characterized by natural sympathetic vibration capability having a predeterminable frequency of response when vibrating;
means for varying the frequency of response of said reed;
electric circuit means with operatively connected battery power means therefore, said circuit means comprising integrated warning alarm means and a circuit portion within said case member adapted to be energized by pulse-amplified resonator contact upon the attaining of a predetermined high level of resonator reed vibration or frequency response which corresponds to a predeterminable dangerously high level of pulse rate; and
said device having a variable range of pulse rates calibrated therewithin for selection according to different needs of different wearer'"'"'s of said device.

Abstract
A rugged, relatively low cost, reliable warning device wearable on a person'"'"'s body, preferably in the form of a bracelet or wristwatch. This device novelly utilizes the principal of natural sympathetic vibration or harmonic response of a fine metal reed, such as a finely drawn tungsten wire, to effect closing of an electrical circuit which hereby emits an appropriate warning signal or combination of signals. The device further embodies adjustable frequency of response calibration selection in combination with the selective electrical circuit features to promptly detect an excessive heartbeat or pulse rate. The signal emitted may be of audio, visual or sensory form or a combination thereof to warn the user against over exertion, stressful situations.
This device is unlike known prior art devices of the strain gauge and piezo-electric types, which rely upon electrical circuit resistance changes, as well as other types of the electromagnetic and pressure transducer types which use electrical circuit impulses to sense pulse rates.
