  • Patent number: 10048778
    Abstract: The described technology provides a force sensor apparatus. An elastic pad may be disposed between two force sensors with a force applicator extending at least partially into the elastic pad. When a force is applied to a force applicator, the force applicator transmits the force to one or both of the force sensors via the elastic pad. In an implementation, the force sensors may be resistive sensors. Since resistive sensors may experience thermal drift due to changes in environmental temperature conditions, the differential resistance between the two resistive sensors allows a temperature-independent measurement of the applied force.

  • Patent number: 8839683
    Abstract: The present invention provides a microscale pressure sensor that exhibits high sensitivity in a small form factor. The sensor is a bridged device in which a photonic crystal waveguide, surrounded by a photonic crystal slab, is suspended over a dielectric substrate. Under applied pressure, the photonic crystal waveguide is deflected toward the substrate, causing a decrease in optical transmission across the waveguide due to the coupling of the evanescent field of the guided mode to the dielectric substrate. In a preferred embodiment, the waveguide is coupled to a photonic crystal microcavity, which increases evanescent coupling.

Two mutually magnetically attracted sliders are positioned on the inner and outer surfaces. The outer slider is moved manually across the outer surface to a predetermined point where the wall thickness is to be detected; the inner slider on the inner surface follows the movements of the outer slider due to the effect of the magnetic attraction. A transducer on the outer slider is used to measure the force required to move a magnet away from the outer surface of the wall. The value of the thickness of the wall at the predetermined point is then derived from the measured force.

  • Publication number: 20120096956
    Abstract: The present invention provides a microscale pressure sensor that exhibits high sensitivity in a small form factor. The sensor is a bridged device in which a photonic crystal waveguide, surrounded by a photonic crystal slab, is suspended over a dielectric substrate. Under applied pressure, the photonic crystal waveguide is deflected toward the substrate, causing a decrease in optical transmission across the waveguide due to the coupling of the evanescent field of the guided mode to the dielectric substrate. In a preferred embodiment, the waveguide is coupled to a photonic crystal microcavity, which increases evanescent coupling.

  • Publication number: 20100326209
    Abstract: A system for resolving the measured forces and moments at VRS attachment points and tire contact patches to a standard format for a wheeled vehicle in a windtunnel. The system reduces the data to arrive at the aerodynamic forces, moments and coefficients. The test vehicle is equipped with one or more wheel force transducers installed between the wheels and the corresponding hubs. A VRS rod or strut attaches to the wheel so that loads through the hub and into the wheel are sensed at both the VRS strut and the tire contact patch. The force transmitted through the hub into the wheel is sensed and measured directly by the wheel force transducer. The combination of measurements from the VRS load cells and the wheel transducers allows the determination of the external forces acting on the vehicle at the tire contact patch, which in turn leads to the aerodynamic forces acting on the vehicle. When combined with the geometry of the vehicle, the aerodynamic moments acting on the vehicle can then be determined.
