    摘要: An isolation amplification circuit having an input stage circuitry and a control circuitry stage interconnected through a galvanic isolation barrier. The input stage circuitry includes a first filter network and a second filter network for supplying first and second output signals in response to the application of first and second electrical input signals. The input stage circuitry includes a first feedback path configured for applying a first feedback signal to a common node of the first filter network to close a first feedback loop around the first filter network and a second feedback path configured for applying a second feedback signal to a common node of the second filter network to close a second feedback loop around the second filter network.

    摘要: An electrical connector having a main support with a front and back, top and bottom, and left and right opposite the left. Fingers extend forwardly from the front of the main support to a tip. The fingers each have a top and bottom and are arranged from left to right of the main support with gaps defined between them. A flexible circuit board has inner and outer surfaces with electrical leads on the outer surface. Openings are defined through the flexible circuit board between the electrical leads. The flexible circuit board is wrapped around the fingers such that the outer surface of the flexible circuit board is supported on both the top and the bottom of the fingers and the openings in the flexible circuit board are aligned with the gaps between the fingers.

    摘要: Multiple wireless sensor assemblies are individually attached to standard biopotential electrodes, which are placeable on a subject's body at locations for biopotential signal recording. The sensor assemblies, which are electrically isolated, simultaneously measure potential voltages from the body sites in accordance with a synchronization. The measured signals are amplified, digitized, and filtered, and then sent wirelessly to a monitoring system. The monitoring system receives multiple sensor signals and constructs biopotential vectors depending on the placement and number of the sensors. The sensor signals are referenced to a common virtual center bias to synthesize a common mode rejection.
