  • Orient a mobile device coordinate system to a vehicular coordinate system
    Patent number: 10168156
    Abstract: An approach is provided by a mobile information handling system that includes a processor, and a gyroscope, a gravity sensor, and a memory each accessible by the processor. The approach identifies, at the mobile device that is moving with a vehicle, when a rotation of the gyroscope is at a near-zero moment, and an acceleration, wherein the acceleration is detected as being on a plane that is near-perpendicular with a gravity sensed by the gravity sensor. Then the detection is made, the approach determines a direction of the vehicle as being parallel to a direction of the detected acceleration. The approach then aligns a coordinate system used in the mobile device based on the determined direction of the vehicle.

  • Nano-electromechanical high-index contrast
    Patent number: 7260287
    Abstract: A nano-electromechanical optical switch includes an input optical waveguide that is provided with an optical signal. At least two output optical waveguides are coupled to the input optical waveguide. The deflection of the input optical waveguide aligns with one of either of the two output optical waveguides so as to allow transmission of the optical signal to one of either of the two output optical waveguides.
