Abstract

A wireless heartbeat-detecting device with electromagnetic interference shielding device is provided with a shielding member that is mounted via downward extended locating legs thereof on a circuit board to locate above a transmitting antenna by a predetermined distance. A heartbeat signal transmitted from the transmitting antenna is shielded by the shielding member and is sent to a nearby corresponding receiver via only a number of limited signal transmitting paths. Therefore, when a multiple sets of such wireless heartbeat-detecting devices are used at neighboring locations, signals transmitted from the devices do not interfere with one another.

Claims

1. A wireless heartbeat-detecting device with an electromagnetic interference shielding device, comprising:

a belt-associated seat for detecting a heartbeat pulse signal from a user and defining an internal space;

a circuit board seated in the internal space of the belt-associated seat, and having a heartbeat detecting circuit for processing the heart beat signal detected by the belt-associated seat and a wireless signal transmitting circuit provided thereon;

a transmitting antenna mounted on the circuit board and connected to the wireless signal transmitting circuit for transmitting a series of heartbeat signals processed and transmitted by the heartbeat detecting circuit; and

a shielding member mounted on the circuit board at a position at where the transmitting antenna is located, and a predetermined spacing height being kept between the shielding member and the transmitting antenna, so that the heartbeat signal transmitted by the transmitting antenna is shielded and is sent to a nearby corresponding receiver only via a limited number of signal transmitting paths.

2. The wireless heartbeat-detecting device as claimed in claim 1, wherein the shielding member is located above the transmitting antenna, and connected to a grounding conductor of the circuit board.

3. The wireless heartbeat-detecting device as claimed in claim 1, wherein the shielding member is a substantially flat plate member.

4. The wireless heartbeat-detecting device as claimed in claim 1, wherein the shielding member has at least two downward extended wing portions at two corresponding ends of the shielding member.
