    摘要： The present invention relates to a control system for a heated conduit for use in a respiratory apparatus. The control system comprises a power supply to provide power to the heated conduit. Additionally, it comprises a heating control circuit configured to control heating to obtain a predetermined temperature and a sensing circuit configured to indicate the temperature of a sensor positioned in the heated conduit as well as a bias generator circuit configured to provide a current to the sensor from a current source such that a voltage drop through the sensor may be recorded by the sensing circuit so that the temperature of the heated conduit is continuously monitored independent of whether the heating control circuit is on or off.

    摘要： A diagnostic system (40) and a diagnostic method for a thermistor amplifier circuit (30) are provided. The system includes a transistor (100) electrically coupled to a controllable variable resistor (102) having a predetermined resistance. The transistor (100) applies a test voltage signal to the circuit indicative of a first temperature value. An amplitude of the test voltage value is indicative of a simulated thermistor temperature value. The microprocessor (190) determines a test temperature value based on the amplitude of an output voltage of the circuit (30). The microprocessor (190) also determines an inaccuracy value based on the test temperature value and the simulated thermistor temperature value.

    摘要： A redundant temperature measurement probe is described that may include any number of features. In one embodiment, the probe includes a pair of resistive sensors, a pair of output wires, and a shared ground wire for a total of three wires. The first and second resistive sensors of the probe can be electrically connected to a controller to measure temperature and detect when a fault in the probe occurs. In some embodiments, the controller can be configured to detect a shift in resistance

    摘要： Provided is a long-life inexpensive electronic clinical thermometer with high measurement accuracy. The electronic clinical thermometer includes a thermistor, a reference resistor, a voltage switch for selectively applying a voltage in order to accumulate electric charge in a capacitor via the thermistor or reference resistor, an A/D converter for detecting a voltage change occurring when removing the electric charge accumulated in the capacitor via the thermistor or reference resistor, and outputting an ON signal while the capacitor has a voltage equal to or higher than a predetermined voltage, a timer for measuring the discharge time by measuring the duration of the ON signal, and an arithmetic processor for calculating the ambient temperature of the thermistor by using the discharge time when removing the electric charge accumulated in the capacitor via the thermistor, and the average value of the discharge times when removing the electric charge accumulated in the capacitor via the reference resistor immediately before and after removing the electric charge accumulated in the capacitor via the thermistor.
