Reading device in wired communication with a probe having an embedded memory device
First Claim
1. A monitoring system for a physiological sensor, comprising:
- a reading device; and
a probe having a housing, wherein the probe is electrically connected to the reading device via a wired interface;
wherein the probe comprises;
a physiological sensor configured as a Wheatstone resistive bridge balancing circuit;
a memory device integrated within the housing of the probe such that the sensor and memory device are prevented from being separated from one another during use, wherein the memory device is electrically connected in parallel with the sensor;
wherein communication between the reading device and the probe occurs via the wired interface utilizing a same number of electrical connections between the reading device and the probe as would be required if the memory device were eliminated.

Abstract
A monitoring system including a reading device electrically connected to a probe via a wired interface. The probe has a physiological sensor/transducer configured as a Wheatstone resistive bridge balancing circuit. Integrated within the housing of the probe to prohibit separation during use by a user is a memory device arranged in parallel with the sensor. Communication between the reading device and the probe occurs via a wired interface utilizing a same number of electrical wires between the reading device and the Wheatstone as would be required without the memory device. Control circuitry selects between one of two modes for accessing either data detected by the sensor or the memory device.
