Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

G01C 1930

US Classification:

74 547, 244165

Abstract:

An inertial control and measurement system is provided for applying inertial control to a vehicle and measuring angular rate of the vehicle. The system includes a control moment gyroscope having a spinning rotor, a gimbal, a gimbal support assembly attached to a spacecraft for allowing rotation of the gimbal about a gimbal axis, and a gimbal motor for rotating the gimbal about the gimbal axis to induce torque. A controller controls the gimbal motor to generate a control torque. The controller further determines an angular rate of the vehicle as a function of a determined torque and a gimbal angle acceleration.

Appl. No.:

10/802072

Inventors:

Lawrence P. Davis - Phoenix AZ, US
Dennis W. Smith - Phoenix AZ, US

Assignee:

Honeywell International, Inc. - Morristown NJ

International Classification:

F16C 33/38

US Classification:

384523, 384526

Abstract:

Method and apparatus are provided for reducing vibration in bearings. There are provided first and second bearing rings with races, rotating members rollingly engaging both first and second bearing races, a cage for aligning the rotating members between the first and second bearing races, and vibration reduction means coupled to the cage. The vibration reduction means preferably comprises one or more resonant spring-mass combinations mounted in or on the cage. Damping means is preferably included with the resonant spring-mass combinations. The resonant frequencies of the unmodified bearing cage are first determined and then the spring-mass combinations tuned so that the spring-mass combinations when attached to the cage absorb vibrational energy that would otherwise excite cage vibrations. By selecting the type of spring-mass combination different vibrational modes can be suppressed and/or controlled.

Inventors:

Long Q. Nguyen - Tustin CA, US
Daniel Bauen - Atlanta GA, US
Cassilyn Bair - Atlanta GA, US
Lawrence E. Davis - Atlanta GA, US

International Classification:

B60B 33/00

US Classification:

16 45

Abstract:

In various embodiments, a caster assembly may include a wheel rotatably coupled to a caster housing and a deflector tab pivotably coupled to the caster housing and offset from an outer wheel circumference for use in moving or traversing obstacles encountered during wheel movement. In some embodiments, the deflector tab may include at least one retaining element configured to hold the deflector tab in a pusher position or allow movement of the deflector tab into a ramp position. In the pusher position, the deflector tab may push a mobile obstacle in front of the wheel motion. In the ramp position, the deflector tab may facilitate moving the wheels over a fixed obstacle.

F16D 55/02

US Classification:

188 68

Abstract:

In various embodiments, a braking system may include an actuator, a pawl gear coupled to the actuator, and a wheel gear plate. The braking system may further include a brake pad, an outer wheel coupled to the brake pad, and a spring washer plate configured to press the wheel gear plate against the brake pad such that the wheel gear plate is configured to inhibit rotation of the outer wheel through friction between the wheel gear plate and the brake pad when the pawl gear inhibits rotation of the wheel gear plate. In some embodiments, the braking system may further include a sensor and the actuator may be triggered to actuate the pawl gear in response to signals from the sensor.

Lawrence P. Davis - Phoenix AZ

Assignee:

Honeywell Inc.

International Classification:

F16F 710

US Classification:

188378

Appl. No.:

7/110076

Inventors:

Lawrence P. Davis - Phoenix AZ

Assignee:

Honeywell Inc. - Minneapolis MN

International Classification:

F16F 500

US Classification:

267122

Abstract:

A vibration damping and isolation apparatus wherein in damping is obtained by purely viscous fluid shear forces. The fluid is sealed in two chambers divided by a orifice to permit fluid flow. Chamber containment of the fluid and chamber volume change is provided by metal bellows which are arranged to provide a constant overall volume. Coulomb forces are avoided by the elimination of rubbing surfaces.
