Heart beat transmitter
First Claim
1. A heart beat transmitter to be worn by an user comprising:
- a housing,a pair of metal plates within said housing,a pair of fastening straps secured to said housing, each of said fastening straps having an elongate conductive rubber plate in contact therewith,each of said conductive rubber plates contacting one of said metal plates in said housing, said conductive rubber plates detecting the heart rate of the user,a circuit board within said housing for decoding the signal received from said conductive rubber plates and transmitting a signal to a receiver, andconductive members connecting said circuit board with each of said metal plates within said housing and establishing an electrical connection therebetween.

Abstract
An improvement of heart beat transmitter includes a circuit board, a pair of conductive rubber posts, a housing, a pair of fastening straps and a pair of conductive rubber plates. The housing is provided with a metal plate and installs the conductive rubber plate jointly with the fastening strap. The underside of the circuit board is provided with conductive spring plate or rubber post to establish a conducting loop with the metal plate to avoid the manufacturing difficulty. On the other hand, the conduction therebetween is enhanced. The conductive rubber plate is provided with an insulating layer to reduce the contacting area with skin. Accordingly, the noise interference is reduced and the performance is increased.
