  • Patent number: 6754762
    Abstract: A pair of buses connect devices and a processor on a backplane. Each device monitors both buses for a bus reset that is produced by the processor on detecting a fault with the active bus, at which time the processor switches to the inactive bus and produces a bus reset signal on the inactive bus, telling the devices to switch to the inactive active bus. The devices are programmed to respond to the reset signal on either bus to make it the active bus.

  • Patent number: 6508437
    Abstract: A spacecraft payload, suspended by an isolator, is locked down during launch by using a compliant member to pull on a pin, clamping the payload against the launch lock. The payload is unlocked, after launch, by heating a shape memory alloy to move the pin to overcome the compliant member, releasing the payload from launch lock. The payload may be re-locked for reentry by heating another shape memory alloy to push the pin against the other shaped memory alloy.

  • Patent number: 6477433
    Abstract: In a position in control, a velocity error is compared to a limit that is a non-linear, continuous and differentiable function of the position error. If the position error is greater than a limit or magnitude, the velocity limit is used for the velocity command; otherwise the position error is used.

  • Patent number: 6319740
    Abstract: Disclosed is a method of forming a multilayer opaque coating on an integrated circuit or multichip module. First, an opaque coating composition is heated to a molten state and the molten opaque coating composition is applied so as to form an opaque coating that overlies active circuitry on the surface of the integrated circuit or multichip module, to prevent optical and radiation based inspection and reverse engineering of the active circuitry. Further coatings are applied over the opaque coating to shield the active circuitry of the integrated circuit or multichip module from the adverse affects of electromagnetic interference and/or high energy radiation.

  • Patent number: 6229615
    Abstract: In a ring laser gyro (RLG), the dither pick off signal is applied to a variable gain amplifier, producing an output that controls the amplitude of the motion of a dither motor connected to the gyro. A square wave is generated from the dither pick off signal and applied to a signal processor with clockwise and counterclockwise signals produced by the motion of the gyro. The signal processor controls a multiplexer to select the gain for the variable gain amplifier by counting the clockwise and counterclockwise signals produced by the gyro motion in a interval (number of whole periods of dither motion) determined by counting the square wave signal produced from the dither pick off signal.

  • Patent number: 6191728
    Abstract: A method is disclosed for targeting a satellite orbiting earth between to sites on earth based on an access time that is transmitted from a ground station. Control momentum gyros are used to change the satellite's attitude for targeting. A gryo rate is selected based the longest time to target. The longest time is a value selected from the access time, the time to reach the target based on the satellite's attitude and the time to reach the target based on the gyro rate.

  • Patent number: 6154691
    Abstract: Controlled momentum gyros are rotated to change the attitude of a satellite as rapidly as possible by rotating them along a great circle path on an imaginary spherical surface around the satellite. Adjustments the gyro rotations are made in two directions, along the spherical surface, as the satellite rotates. All the stored angular momentum in the gyros is used to rotate the satellite, rather than limiting the rotation of the gyros to avoid instabilities from singularities in traditional control laws.
