  • Bio-electric noise cancellation system
    Patent number: 4890630
    Abstract: A device and method are provided for bio-electric monitoring apparatus to cancel bio-electric noise on the body of a patient. The device comprises a plurality of monitoring electrodes for reception of bio-electric signals from the body, each monitoring electrode having a conductive lead and a surrounding shield. The device further has a driving electrode for transmission of a correction voltage to the body. The driving electrode has a conductive lead and a surrounding shield. The device has a signal averager with an input and an output. The monitoring electrode leads are connected to the input of the signal averager. An amplifier is connected to the output of the signal averager which has its output connected to the driving electrode lead to provide the correction voltage. The shield around the driving electrode lead is conductively connected to the output of the amplifier.
