摘要： In an integrated circuit device having a microelectromechanical-system (MEMS) resonator and a temperature transducer, a clock signal is generated by sensing resonant mechanical motion of the MEMS resonator and a temperature signal indicative of temperature of the MEMS resonator is generated via the temperature transducer. The clock signal and the temperature signal are output from the integrated circuit device concurrently.

摘要： In an embodiment, an integrated circuit includes: a switched capacitor coupled between a supply voltage node and a divider node, where a thermistor external to the integrated circuit is to couple to the divider node; an analog-to-digital converter (ADC) coupled to the divider node to receive a voltage at the divider node and generate a digital value based thereon; and a controller coupled to the ADC to determine a temperature associated with the thermistor based at least in part on the digital value.

摘要： Low-cost techniques for sensing ambient temperatures in a container or package using phase change materials are provided. In one aspect, a temperature sensor is provided. The temperature sensor includes: at least one phase change material configured to transition from an amorphous state to a crystalline state upon exposure to temperatures above a predetermined threshold temperature for a given duration. A method of monitoring temperature exposure of a consumer good using the temperature sensor is also provided.

摘要： An AD conversion apparatus includes an AD conversion unit; a reference voltage switching unit that is disposed between an output of a sensor and an analog input terminal of the AD conversion unit and is connectable to the output of the sensor and a plurality of reference voltage lines; and a control unit to control switching the reference voltage input to the AD conversion unit by connecting the reference voltage switching unit to one of the reference voltage lines and to the output of the sensor. An analog output value of the sensor is input to the analog input terminal of the AD conversion unit via the reference voltage switching unit and is converted into a digital value.

摘要： A temperature measurement probe (130) for use in a magnetic resonance environment, includes an elongated substrate (202), at least one highly resistive, electrically conductive traces (200, 200a, 200b, 200a′, 200b′) one printed at least one thermistor (204) disposed on the substrate and electrically connected with the trace. The thermistor is configured to be placed in thermal communication with a patient in the magnetic resonance environment. In some embodiments, the printed trace may be carbon-based, silicone based, or may be a doped semiconductor material.

摘要： A temperature detection circuit is provided with a temperature measuring circuit, a computing circuit, a temperature monitoring circuit, and a diagnostic signal generation circuit. The temperature measuring circuit outputs, to a measurement node, a temperature measurement voltage corresponding to a temperature. The computing circuit, calculates the temperature on the basis of the temperature measurement voltage. In the cases where the temperature measurement voltage is within a predetermined abnormal voltage range, the temperature monitoring circuit validates an abnormality detection signal indicating a temperature abnormality. When fault diagnosis of the temperature monitoring circuit is carried out, the diagnostic signal generation circuit supplies a diagnostic signal to the measurement node, and changes the temperature measurement voltage.

摘要： A hybrid electronic sensing component comprises an integrated circuit attached to an analogue circuit into which at least one sensing element has been integrated. The hybrid sensing component provides an output in digital form in response to a quantifiable change in its environmental conditions. The sensing functionality is separated from the data processing, which reduces the effect of self-heating due to the power consumption in the processor.
