    Abstract: The disclosed invention provides a method that exploits the correlations in the statistical properties of one inertial sensor to another. Among the dominant noise sources, the additive noise terms for different sensors are uncorrelated, however, there may be correlations between the random drift of different sensors. The method of the present invention estimates these correlations from a finite amount of calibration data in order to calculate coefficients for the optimal linear combination of multiple sensor signals. The method is a means of combining the multiple sensor outputs to obtain a virtual sensor signal with reduced drift, and in a far more time efficient and less processor intensive way than the prior art.

    Abstract: MEMS devices fabricated using inexpensive substrate materials such as paper or fabric, are provided. Using paper as a substrate, low cost, simple to prepare, lightweight, disposable piezoresistive sensors, including accelerometers are prepared. Signal-processing circuitry can also be patterned on the substrate material. The sensors can be utilized as two-dimensional sensors, or the paper substrate material can be folded to arrange the sensors in a three dimensional conformation. For example, three sensors can be patterned on a paper substrate and folded into a cube such that the three sensors are orthogonally positioned on the faces of a cube, permitting simultaneous measurement of accelerations along three orthogonal directions (x-y-z). These paper-based sensors can be mass produced by incorporating highly developed technologies for automatic paper cutting, folding, and screen-printing.

  • Patent number: 9555758
    Abstract: A safety arrangement for a vehicle. The safety arrangement has a control unit; one or more sensors, a road detection arrangement; and one or more vehicle safety systems. The control unit processes the signals from the sensors and determines whether the vehicle is travelling over rough terrain, entering a ditch-like feature, or is airborne. The control unit will activate one or more of the vehicle safety systems if it is determined that the vehicle is travelling over rough terrain, entering a ditch-like feature, or is airborne. Signals, or derived quantities, from the sensors are compared against a threshold to determine whether to activate a vehicle safety system. A first threshold level is used if the vehicle has not or is not likely to leave the road, and a second threshold level is used if the vehicle has or is likely to leave the road.

  • Patent number: 9134143
    Abstract: In an absolute position detector, a relative error calculation circuit calculates, at times indicated by a clock signal C1, a relative error E between an output ?2 from an absolute position detection sensor and a position output ?1 from a high-resolution position detection sensor. An abnormality judgment unit judges whether the relative error E exceeds a preset abnormality judgment value. A clock switching unit outputs, as the clock signal, a high-speed clock CH having a period shorter than a noise generation period when the relative error E is judged as exceeding the preset abnormality judgment value, and outputs a slow-speed clock CL in other cases. A counter measures, based on the clock signal C1, a duration in which the abnormality detection signal AF is maintained HI, and outputs an alarm when the duration exceeds the noise generation period.
