Abstract:
1. A contact type pulse measurement device, installed to a handheld equipment for measuring a pulse condition of a user holding said device by a hand, wherein said contact type pulse measurement device comprising: a first active sensor electrode and a second active sensor electrode having corresponding opposite polarities with each other, and said two active sensor electrodes respectively coupled with said pulse measurement device by a conductive wire; a bio-potential sensor, coupled to said two active sensor electrodes; a bio-signal measurement unit for receiving a signal transmitted from said bio-potential sensor and coupling to a negative feedback difference common mode signal unit and a buffer/balanced circuit, wherein said buffer/balance circuit feeds back a signal from said negative feedback difference common mode signal unit to said bio-signal measurement unit, and wherein said both negative feedback difference common mode signal unit and buffer/balanced circuit providing a circuit with a self common point electrode potential; an analog filter/amplifier for receiving a signal transmitted from said bio-signal measurement; an associative processing unit, to receiving a signal processed by said analog filter/amplifier for selectively process and compare a parameter setting; and a signal processing unit for displaying a pulse data on a display device after said signal is processed and feeding said signal back to said associative processing unit to set a system parameter.
