  • Patent number: 6904377
    Abstract: System and method for measuring force-dependent gyroscopic sensitivity. A force-effect model of the effects of acceleration on the output of a gyro triad is determined. Rotation sequences are then devised to permit excitation and observation of force-effect model parameters in order to provide calibration information for these parameters. A state diagram containing the gyro triad force-effect model parameters is derived from the force-effect model, where moving from one position in the state diagram to another position indicates the gyro triad error which would occur in rotating the gyro triad according to a corresponding motion. Searching for all possible closed loop paths achievable through the state diagram, by a multiple-axes rate table with a specified number of rotations, to separate gyro triad error calibration from the accelerometer calibration.

  • Publication number: 20040189341
    Abstract: A power-on self test (“POST”) apparatus and method for the power supply of PC, work station and server systems. A POST switch is installed in the power supply portion of the PC to allow the user to conduct self-testing of the power supply during troubleshooting. When the PC system becomes inoperative, activating the POST switch on the power supply will quickly determine whether the problem lies in the power supply or in the computer main board. The POST switch, when activated by the user, creates a power loop within the power supply by bringing a predetermined input terminal in the power supply to ground. If the power supply is operational, the cooling fan, and/or an LED indicator, will turn on, indicating its status. If the power supply is malfunctioning, the fan or the LED will not turn on, alerting the user that the power supply is where the failure lies.
