  • Patent number: 10481078
    Abstract: A hygrometer includes a heat transfer section extending from a measurement space toward an outside space separated from the measurement space, a heat release amount control unit that causes heat to be released to the outside space from the heat transfer section such that an amount of heat released to the outside space is made constant, and a computation device that calculates a humidity of the measurement space. The computation device calculates the humidity from a heat transfer section temperature and a measurement space temperature using a relational expression based on a heat balance in the heat transfer section when condensation is occurring in a portion, of the heat transfer section, located within the measurement space in a state where the amount of heat released to the outside space from the heat transfer section is made constant by the heat release amount control unit.

  • Patent number: 10317303
    Abstract: A unitary tension and torque calibration apparatus consists of a unitary device which has a hollow rotary torque transducer for calibrating the torque of a rotating torque tightening tool. At the same time the torque of the tool is being calibrated, a reaction arm attached to the transducer reacts against rotation to induce stress on the metal component being calibrated. The axial forces generated within the metal component by rotation, opposed by the reaction arm, results in tension which is calibrated by a piston driven load cell secured directly to the transducer. Display devices attached to the transducer and load cell simultaneously and contemporaneously show the calibrated results.

  • Patent number: 10295559
    Abstract: To calibrate an accelerometer, a rotating member is rotated over multiple periods, thereby causing the accelerometer attached to the rotating member to repeatedly turn over. A processor obtains acceleration measurements as the accelerometer turns and determines a set of local minima and maxima of the acceleration measurements. Based on these local minima and maxima, the processor determines a sensitivity of the accelerometer. The processor stores the sensitivity for use in adjusting subsequent accelerometer measurements, thus calibrating the accelerometer.

  • Patent number: 10282965
    Abstract: Techniques are disclosed for using synthetic jet technology as an air delivery device for sensing applications. In particular, a synthetic jet device is used to deliver a controlled airflow or other fluidic flow to a sensor measurement area. Such a sensing system can be used to detect accurate concentration of target features present in the ambient surroundings, such as gases, particles, solutions, mixtures, and any other environmental features that can be sensed from a controlled airflow. An example application is air quality monitoring by using one or more synthetic jet devices to deliver a known or otherwise controlled airflow to a sensing area, thereby allowing for detection of harmful or otherwise unacceptable concentrations of particulate matter, gases, or air pollutants. In some embodiments, a synthetic jet device is operatively coupled with a sensor via a flow channel in a common housing, so as to provide a controlled flow sensing system.
