摘要： Energy delivery devices with a flexible circuit. The energy delivery devices may be used in the treatment of human tissue, and the flexible circuit move or flex during use. The flexible circuit may include an electronic component and a trace connected with the electronic component. The trace may have a plurality of sections that provide parallel current paths over a portion of the trace. Alternatively, the flexible circuit may include a plurality of traces that are connected with the terminal of the electronic component to provide parallel current paths over their entire length to the terminal of the electronic component. These redundant parallel current paths improve device reliability.

摘要： 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.

摘要： A measuring apparatus and a physical characteristic measuring device are provided. The measuring apparatus includes at least one first physical characteristic measuring device and a data processing device. The first physical characteristic measuring device includes a sensor, a signal processing circuit, and a transmission path. The sensor generates a measurement signal according to the physical characteristics of a location where the first physical characteristic measuring device is located. The signal processing circuit converts the measurement signal into a first processed signal. The transmission path is able to be electrically connected to a second physical characteristic measuring device. The transmission path passes a second processed signal of the second physical characteristic measuring device to the data processing device in response to the first physical characteristic measuring device and the second physical characteristic measuring device being electrically connected to each other.
