Abstract: A single wire interface for a transducer transmits the transducer output as a frequency modulated signal over one single wire during one interval. During a second interval a reference signal is transmitted as a frequency modulated signal. Both the transducer output and the reference signal output are processed by the same circuitry during the respective intervals to provide both frequency modulated signals. The frequencies of the two signals are measured and then the ratio of the two periods which is the reciprocal of the two frequencies is calculated. This ratio is the direct measure of the output of the transducer and when provided eliminates sources of errors.

Abstract: A fluid pressure sensor for a lead or catheter intended for placement in a living organism, such as a human heart, includes a rigid annular or tubular supporting structure and a piezoelectric element disposed on at least a portion of the outer surface thereof. The piezoelectric element delivers an electrical signal when subjected to a pressure variation, and exhibits circumferential sensitivity. The rigidity of the sensor is defined to satisfy predetermined criteria to ensure that the sensor, when sensing pressure transferred to the sensor through an on-growth of tissue on the sensor, which is at least 90% of the signal which the sensor would emit without the on-growth.

An element portion for detecting pressure and a circuit portion having a signal processing function are integrally accommodated in the same package. An interface section 24 optimized to interface with external wiring, an A/D conversion section 25 for digitally encoding an analog processed detection signal of the sensor, and a digital processing section 26 for converting the digitized signal into a desired serial signal are added to the circuit portion 2. The entire circuit portion is constituted by at most two ICs alone, and a selection can be made between two output forms including an analog processed detection signal and a digital processed detection signal.

Abstract: An interface circuit for interfacing a semiconductor transducer sensor to a patient vital signs monitor is disclosed. In one embodiment, the interface circuit includes a power supply circuit that receives an excitation power signal generated by the patient monitor, and derives therefrom unregulated and regulated supply voltages for use by the electrical components on the interface circuit. Also generated by the power supply circuit is an appropriate sensor excitation signal for the semiconductor transducer. In another embodiment, the interface circuit further includes receiving circuitry for receiving a sensor output signal generated by the transducer sensor. A scaling circuit then scales that signal into a parameter signal that is proportional to the physiological condition detected by the sensor, and that is also proportional to the excitation power signal generated by the patient monitor. If necessary, the interface circuit further includes isolation circuitry, for electrically isolating the transducer sensor from the patient monitor.

Abstract: An electronic sensing circuit, which can be used in place of a linear variable differential transformer (LVDT) has four piezoresistor elements in a Wheatstone bridge configuration. A source voltage is applied across a first pair of bridge points, and the resulting junction voltages appearing at a second pair of bridge points are applied to a pair of inverting amplifiers in balanced configuration which provide first and second output voltages which change relative to each other depending upon the direction and amount of pressure applied to the piezoresistor elements in a manner similar to the output voltages provided by an LVDT.
