  • Patent number: 11067519
    Abstract: A strain detecting device includes a sensor portion and a covering elastic deformation member. The elastic deformation member generates heat when compressed and absorbs heat when expanded, resulting in heat flux. The sensor portion includes first and second heat flux sensors, each of which has first and second sensor surfaces formed opposite to each other. Each sensor outputs a strain-indicating signal of a polarity when the heat flux passes through the sensor, from the first sensor surface to the second sensor surface, and outputs a strain-indicating signal of an opposite polarity when the heat flux passes through the sensor in reverse, from the second sensor surface to the first sensor surface. The first sensor surfaces are opposed to each other across a heat absorbing member interposed between the sensors. The sensor portion generates signals based on the heat flux generated by deformation of the elastic deformation member.

  • Patent number: 11047816
    Abstract: A method for measuring thermal diffusivity/conductivity of a microscale sample includes placing a metallic disk atop the sample, and disposing a nanomembrane over the sample and over the metallic disk so that the nanomembrane, so that the metallic disk, the nanomembrane and the sample are in thermal equilibrium with one another. A laser beam is directed to fall onto the nanomembrane over the sample, while a radiation sensor is operated to detect photoluminescent radiation emitted by the nanomembrane in response to the laser beam. A spectral shift in the detected photoluminescent radiation emitted by the nanomembrane is determined, and thermal diffusivity/conductivity is calculated from the determined spectral shift of the photoluminescence.

  • Patent number: 11041764
    Abstract: A sensor system for detecting events is provided. The sensor system includes a sensor and a read-out interface. The sensor includes a transducer and a memory device. The transducer detects an event and generates a sensor signal in response to the event. The memory device includes a floating-gate with a sensing interface coupled to the transducer. The sensing interface has an energy barrier that leaks electrons at a predetermined electron leakage rate through Fowler-Nordheim (F-N) tunneling. The sensor signal alters a geometry of the energy barrier to change the electron leakage rate. The read-out interface is communicatively coupled to the memory device and retrieves data stored on the memory device for analysis. The event and a timestamp of the event are identifiable from the stored data.

  • Patent number: 11035809
    Abstract: To provide a thermal diffusion factor measurement device, a thermal diffusion factor measurement method and a program capable of measuring thermal diffusion with high accuracy, even when an object to be measured has anisotropy in which thermal diffusion factors differ greatly between the in-plane direction and the thickness direction and a thick thickness. In a thermal diffusion factor measurement method, a heating location H on a tabular sample is made to generate periodically varying thermal waves and the thermal waves at a detection location S on the sample are detected by a non-contact temperature sensor. In addition, the phase delay of the thermal waves at the detection location S is detected in consideration of a detection sensitivity distribution DS of the non-contact temperature sensor and the thermal diffusion factor in the in-plane direction of the sample is measured using the phase delay.

  • Patent number: 11015434
    Abstract: A method and system are provided for detecting the wax appearance temperature (WAT) of a hydrocarbon fluid sample. The hydrocarbon fluid sample is run through a microfluidic channel at controlled temperatures while sensing the pressure drop across the channel. The WAT is determined by finding a temperature at which the pressure (drop) across the microfluidic channel caused by a temperature reduction of the hydrocarbon fluid sample does not stabilize over a given time interval, thereby establishing the WAT as being at that temperature or between that temperature and a previous higher temperature where the pressure (drop) stabilized over time.
