| titleOfInvention |
Portable device for measuring heartbeat rate with compensation for extraneous signals |
| abstract |
A device mounted on and coupled to the body of the wearer for measuring and visually displaying the pulse rate or other body functions. A primary sensor is positioned on the skin at a position to sense arterial pressure variations and generate a pulse signal responsive thereto while a secondary sensor is positioned close by to generate signals due to extraneous influences of the body and environment. These extraneous signals are subtracted from the pulse signal to increase the accuracy thereof. |
