Abstract: A force sensor includes at least one cavity defining at least two surfaces having different orientations. On each of said surfaces is disposed at least one respective detection structure sensitive to a pressure exerted on the corresponding surface. A resiliently deformable medium at least partially fills the cavity by coming into contact with the surfaces and defines a detection surface, on which a force to be detected is likely to be exerted. The application of this force is likely to generate stresses on each detection structure due to the transmission of forces by the medium.

Abstract: A system for determining power generated by a nuclear core assembly immersed in heat transfer fluid. Light radiation reflected from the blades of a rotor located in the heat transfer fluid is used to determine the rotation speed of the rotor. The flow rate of the heat transfer fluid is determined based on the rotation speed. A difference in temperature between an inlet and an outlet of the assembly is calculated. Power generated by the assembly is determined based on the flow rate and the temperature difference.

Abstract: Exemplary arrangements relate to a system that includes at least one wireless dance mat and a base device, as well as a method of operation and communication which provides for rapid and accurate signals indicative of the state of a plurality of pressure sensors in the dance mat. Each pressure sensor is configured to sense pressure resulting from person contact with the dance mat.

A printer device includes a printer applicator, a position sensor, and a reservoir for compositions for the cosmetic style. A display of the printer device represents the portion of skin as a plurality of guide segments, and represents the printer applicator as a visual indicator relative to the plurality of guide segments based on the position sensor. The depiction of the visual indicator responds to changes in the position of the printer applicator relative to the portion of the skin to visually guide the individual to accurately apply the cosmetic style, and a feedback device alerts the individual if the application deviates from the portion of the skin. These approaches enable the individual to correct application of the composition in real time.
