    摘要： A method, system and inertial navigation unit are provided in order to facilitate location determination by calibrating a location determined by an inertial navigation unit. The method may receive a magnetic pulse, such as a magnetic pulse generated by a lightening strike, with a plurality of first magnetometers and with a second magnetometer co-located with the inertial navigation unit. The method may also compare a representation of the magnetic pulse received by the plurality of first magnetometers to a respective representation of the magnetic pulse received by the second magnetometer. Further, the method may correct the location determined by the inertial navigation unit as a result of the comparing of the representation of the magnetic pulse received by the plurality of first magnetometers to the respective representation of the magnetic pulse received by the second magnetometer.

    摘要： The physical quantity measuring apparatus includes a first function of generating voltage used for position-controlling a movable body, a second function of detecting a position of the movable body during a position detecting period, a third function of calculating a control amount necessary to keep the movable body at a predetermined position on the basis of a detection result by the second function, and causing the first function to generate a control voltage corresponding to the calculated control amount to keep the movable body at the predetermined position during a position controlling period, and a fourth function of setting the position detecting period and the position controlling period in a time-sharing manner so that the position detecting period and the position controlling period do not overlap with each other.

    摘要： A precessional device having independent control of the output torque generated by the device and the oscillation rate of the device is disclosed. The device comprises a rotor supported by an axle wherein the ends of the axle are supported by a circular race. The circular race is rotatable, and may be driven by a motor or other means, thereby controlling the oscillation rate of the device independently of the output torque arising from the rotation rate of the rotor. The motor may be controlled by a control program that adjusts the rotation rate of the circular race to modify the shape of the resistance curve.
