摘要： Photodiode systems, methods, devices, and circuitries are provided for determining a material property and/or determining environmental characteristics. In one embodiment, a measurement device includes a first member, a second member rotatably coupled to the first member at a pivot that affixes the first member to the second member. The first member and the second member are configured to pivot between a closed position, where the first member and the second member contact one another, and an open position where the first member is rotatably separated from the second member. An infrared emitter is disposed within the first member, the infrared emitter faces the second member. An infrared sensor is disposed within the second member facing the first member, where when the first member and the second member are in the closed position, the infrared emitter and the infrared sensor are misaligned.

摘要： A thermal conductivity estimation method includes: measuring temperature distribution of a measurement sample surface in a steady state by partially heating the measurement sample under predetermined heating conditions; calculating temperature distribution of a sample model surface by performing a heat-transfer simulation on the sample model of the same shape as the measurement sample for a plurality of combinations of provisional thermal conductivities and heating conditions; making a regression model, whose input is temperature distribution of the measurement sample surface and whose output is a thermal conductivity of the measurement sample, by a machine learning technique using training data in a form of a calculation result of the plurality of combinations and the temperature distribution obtained from the plurality of combinations; and estimating the thermal conductivity of the measurement sample by inputting a measurement result of the temperature distribution of the measurement sample surface into the regression model.

摘要： A method includes receiving a gas or gas mixture through a flow sensor. A flow velocity, volumetric, or mass flow are determined. The method also includes determining a sound velocity of the gas or gas mixture by an ultrasonic sensor. A density of the gas or gas mixture is correlated from the sound velocity. The method also includes positioning a microthermal sensor in an area with less flow or no flow of the gas or gas mixture. A thermal conductivity and thermal diffusivity of the gas or gas mixture at the one or more temperatures is determined. The method also includes connecting a processor to the microthermal sensor to calculate an energy of the gas or gas mixture based on a calorific value, the temperature and the volume or mass flow. Specific quantities for gas quality are correlated.

摘要： The present invention is a system and method for determining effective ground thermal properties. Accurate prediction of required loop length for geothermal heat exchange systems is critical for optimizing performance and associated cost, yet limited by lack of knowledge of the effective average thermal properties of the surrounding ground. Testing involves first charging the ground loop by circulating fluid at constant temperature and constant rate of heat input, then halting heat input and monitoring the ground loop temperatures during discharge. One aspect of the invention is to enable separate determination of effective ground thermal conductivity and volumetric heat capacity first by adopting design elements resulting in improved reproducibility, and second by evaluating thermal conductivity near the time when the quotient Q of later discharge temperature to start-of-discharge fluid temperature is almost independent of volumetric heat capacity. Evaluation discharge times are specific to both ground loop design and charging conditions.
