  • Patent number: 11467046
    Abstract: In a stress measurement method, an object to be measured is vibrated at a plurality of oscillation frequencies, and a temperature amplitude of the object to be measured is measured by using a temperature sensor. Parameters of a one-dimensional heat conduction equation described below are identified by performing curve-fitting, on the basis of the one-dimensional heat conduction equation, on a measurement value of the temperature amplitude with respect to frequency characteristics of a temperature change component and a phase component based on a thermoelastic effect. The frequency characteristics are obtained at the plurality of oscillation frequencies. The one-dimensional heat conduction equation indicates a theoretical solution of a temperature amplitude on a surface of a coating film based on heat conduction and the thermoelastic effect of each of a substrate and the coating film. Then, a stress of the object to be measured is obtained based on the identified parameters.

  • Patent number: 8840548
    Abstract: The information relating to physical and/or biomedical parameters of a person carrying out, in real conditions, an activity distinguished by high mechanical stresses is detected by sensors (10, 12, 16, 18, 20, 22, 30) which are mounted on, or form part of, a garment worn while carrying out said activity. During all the stages of said activity this information is converted into data in digital format which are stored in an electronic recording device (100) or “data logger”. Advantages: the stored data may be used by other persons also far from the location where the activity is being performed and/or at a later time.

  • Publication number: 20140230571
    Abstract: An apparatus is disclosed comprising a suite of sensors for measuring instant static and dynamic pressure, speed of the water flowing past the vessel in the direction of travel of the vessel, acceleration of the vessel in the direction of motion, and position of a vessel, such as a row boat. A microprocessor receives data from the sensors and calculates power expended by the rower, paddler, or other human or non-human power source by finding the total of all forces impinging upon the vessel and passengers, thereafter multiplying by the speed of the water flowing past the vessel in the direction of travel of the vessel. In one embodiment data is stored for later analysis or for downloading to a computer or other data storage device.

  • Publication number: 20140224040
    Abstract: Steering wheel hand detection systems are disclosed herein. The systems can optionally be used with a system for identifying the presence and/or location of a driver's hands on the steering wheel. The systems include a sensor mat including a plurality of sensor loops arranged in the steering wheel to achieve multiple sensing zones. Because the systems include a sensor mat including a plurality of sensor loops, the systems can be implemented in steering wheels having different designs. The systems can also be implemented to achieve different numbers and/or types (e.g., tap detection, swipe detection, grip detection, etc.) of sensing zones. Additionally, the systems can be implemented in a way that reduces the likelihood of crosstalk due to wire routing.

  • Patent number: 8789430
    Abstract: The invention consists of a measurement device for measuring the force applied by a contact member on the surface of a sample, comprising a vacuum or controlled atmosphere chamber in which there are housed the sample and the contact member, mechanical means for transmitting the force exerted by the contact member in the form of the displacement of one or several flexible members and one or several sensors suitable for measuring said displacement. The device comprises motor-driven linear micropositioners incorporated inside the vacuum or controlled atmosphere chamber for positioning sensor(s). As a result of the system, it is not necessary to break the vacuum to calibrate the sensors, saving time and facilitating the measurement.

  • Patent number: 8757015
    Abstract: A method for determining the plasto-elastic properties of a test sample, which can be affected by the action of pressure, includes pressing a test body against a surface of the test sample with a defined force. Plasto-elastic changes of the surface resulting therefrom are recorded during and/or after the pressure application. A centrifugal force generated by rotating the test body around an axis is utilized as a pressure force which is generated by radially movably guiding the test body, which is disposed between the test sample and the axis, relative to the radially fixed test sample.
