A control system for a heated conduit in a respiratory apparatus includes a power supply configured to provide power to the heated conduit and a heating control circuit configured to control an amount of heat generated in the heated conduit. The control system further includes a sensing circuit configured to indicate the temperature of a sensor positioned in the heated conduit by comparing a reference voltage with a sum of a voltage drop through the sensor and a voltage provided to the sensor by the power supply when the heating control circuit is on. When the heating control circuit is off, the voltage drop through the sensor is solely due to current provided by a current source.

A circuit measures temperature in a charging handle 150 of an electric vehicle charging station (EVSE) 100. A temperature sensor is connected between a control pilot line 115 and ground line G in the charging handle of the EVSE. The control pilot line transmits a square wave signal CP having positive and negative portions, to an electric vehicle, according to the SAE J1772 standard. A temperature monitor 300 in the EVSE, coupled to a pilot signal measurement circuit 230 in the EVSE, measures the negative portions of the square wave signal resulting from the temperature sensor conducting current in response to changes in temperature in the handle. Temperature measurement of the charging handle is achieved without significant added cost or complexity, by reusing existing components in the EVSE, with little or no modification required to EVSE electronics, and minimal modification of the handle.
