    摘要: A bi-stable magnetic switch assembly is provided that comprises a stator and a rotor, which is configured for rotation with respect to the stator between a first latched position and a second latched position. The stator and the rotor cooperate to form a first magnetic path and a magnetic path having a shared portion. A spring, which is coupled to the rotor, biases the rotor toward the first and second latched positions when the rotor is in the second and first latched positions, respectively. At least one magnet is fixedly coupled to either the stator or the rotor. The magnet is included within the first magnetic path and configured to produce a magnetic latching force that biases the rotor toward first latched position when the rotor is closer to the first latched position than to the second latched position, and toward the second latched position when the rotor is closer to the second latched position than to the first latched position. At least one coil is fixedly coupled to either the stator or the rotor and, when energized, alters the flux in the second magnetic path to reduce the magnetic latching force.

    摘要: The present invention provides an optical element switching mechanism that overcomes many of the disadvantages found in the prior art. The switching mechanism uses a balanced arm, with an optical element attached at one end of the arm. The arm is suspended on a axis that allows it to rotate from a first position to a second position. The arm is balanced to provide low force disturbance during this movement. A spring is coupled to the arm that provides the rotational energy to move the arm. The spring is coupled such that its neutral position is between the first and second positions, and thus the spring provides the energy to move the arm from the first position to the second position and vice versa. A latch mechanism is also provided for selectively holding the arm in the first position or second position. Additionally, the latch mechanism can provide additional energy needed to catch and move the arm into final position.

    摘要: A method and system for calculating a control function for a structural system (10) that can be used to determine an appropriate control force to apply to an active member (18) within a stationary member (12) on the structural system (10). An active member (18) and a stationary member (12) are defined as a two-mass system in which the active member (18) and the stationary member (12) move in opposite directions. The stationary member (12) is mounted to an isolation subsystem (14) that is composed of six isolators (28) at multiple degrees of freedom. The isolation subsystem (14) is softer than the stationary member (12), active member (18) and a spacecraft surface (16) due to a damping element (32) of the isolation subsystem (16). The isolation subsystem (16) is mounted to the spacecraft (16) and decouples the spacecraft (16) from the stationary member (12) and thus the active member (18). An accurate control force for the active member (18) can be determined based upon the above structure (10).

    摘要: A dynamic unbalance compensation system that compensates for dynamic unbalance of a rotating assembly on a vehicle, such as a spacecraft, to compensate for the presence of a dynamic unbalance moment. The system includes a vehicle, such as a spacecraft, a rotational assembly mounted on the vehicle and rotatable about an axis of rotation relative to the vehicle, and one or more momentum devices mounted on the rotational assembly and generating a momentum vector component perpendicular to the axis of rotation. The one or more momentum devices generate a compensation torque during spinning of the rotational assembly so as to compensate for dynamic unbalance of the rotational assembly.
