Abstract
Abstract @ A connector (3) for connecting a transducer (1) to a monitor (2) in a system for monitoring physiological conditions in humans and other animals includes means (4) for transforming the impedance level of signals from the transducer to a level appropriate for the monitor and for drawing and adapting power from the monitor for effecting this impedance transformation. The connector (1) may also include one or more of the following means (5) a mechanism for adjusting the offset or sensitivity of the signal from the transducer; a mechanism for detecting the absence of the transducer; a mechanism for detecting an open circuit between the monitor and the transducer; a device for converting power drawn from the monitor to direct current where the power drawn from the monitor is, before conversion, either sine wave or pulsed; a mechanism for regulating the current from the monitor; and a mechanism for eliminating common-mode voltage errors from the transducer signal.
