20060064245, Mar 23, 2006

Filed:

Sep 20, 2004

Appl. No.:

10/945373

Inventors:

Eric Gilbert - Shoreline WA, US

International Classification:

G08G 1/16

US Classification:

701301000

Abstract:

In the present disclosure, systems and methods for preventing collisions between a ground services vehicle and other objects are described. In one embodiment, a system includes a digital three dimensional map of the outer dimensions of the ground vehicle, a micro radar device, a comparator, and an indicator. The micro radar device is secured to the ground vehicle. A comparator signals when an object is within a predetermined envelope around the outer dimensions of the ground vehicle. The comparator receives signals from the micro radar device, and includes dimension data from the three dimensional map. The indicator is responsive to the signal from the comparator. The indicator alerts of possible and pending collision when the predetermined envelope is breached. The indicator may also activate a brake mechanism to stop the ground vehicle. Methods for carrying out the invention by sensing a breach of the envelope and stopping the vehicle are also disclosed.

International Classification:

B64C 27/00
F15B 21/00
F15B 15/20

Abstract:

A tail-rotor vibration dampener system for an aircraft is provided. The system includes a fuselage and an open rotor assembly including a powerplant and a set of rotor blades. The system further includes at least one actuator unit connecting the open rotor assembly to the fuselage. The actuator unit includes a hydraulic actuator controlling a position of the open rotor assembly in relation to the fuselage and a dampening device operable to cancel a vibration emanating from the open rotor assembly. The system further includes a computerized vibration dampening controller, including programming to determine a frequency of the vibration emanating from the open rotor assembly and control the dampening device to cancel the vibration emanating from the open rotor assembly based upon the frequency.

Abstract:

Hybrid multirotor vehicles and related methods are disclosed herein. An example aircraft includes a battery, a rotor coupled to a wing, a motor operatively coupled to the rotor, and a processor operatively coupled to the motor. The processor to is cause the motor to operate in a first motor operational state. The rotor is to operate in a first rotor operational state when the motor is operating in the first motor operational state. The processor is to cause the motor to switch from operating in the first motor operational state to a second motor operational state. The rotor is to operate in a second rotor operational state when the motor is in the second motor operational state. The motor is to provide electrical energy to the battery in the second motor operational state and the rotor is to autorotate in the second rotor operational state.

Abstract:

A system, apparatus, and method for testing a squib circuit. An electrical signature of the squib circuit is monitored when a test switch in the squib circuit is activated. The electrical signature of the squib circuit is based on characterizing resistors electrically connected to squibs in the squib circuit in which each characterizing resistor in the characterizing resistors has a resistance value. A health of each squib in the squib circuit is determined based on the electrical signature of the squib circuit.

International Classification:

G01K 7/16
B64D 45/00

Abstract:

A method for monitoring thermal events in an aircraft engine compartment includes obtaining first sensor data from a first sensor located within an engine compartment of an aircraft. The method also includes determining a time series moving average based at least in part on a subset of the first sensor data. The time series moving average is indicative of an average temperature rate-of-change of the engine compartment. The method further includes determining a standard deviation of the time series moving average and detecting a trend of temperature rates-of-change that satisfy a rate-of-change criterion. The rate-of-change criterion is based on a multiple of the standard deviation, and the temperature rates-of-change are based on temperatures of the engine compartment. The method also includes generating an alert in response to detecting the trend. The alert is indicative of a thermal event associated with the engine compartment.

Appl. No.:

13/926809

Inventors:

Eric Gilbert - Saint Louis MO, US
Grant Baker - Alexandria VA, US

International Classification:

B32B 37/14
C08L 29/04

US Classification:

156285, 524503, 524557, 156 60

Abstract:

The invention relates to joined fiber reinforced composite structures with continuity of fiber reinforcement across adhesive-to-substrate boundaries. Use of a thermal gradient to control the extent of infusion of resin blocking substances into fiber reinforced material, and subsequent resin infusion and resin blocking substance removal, during manufacture of components to be subsequently bonded, provides partially exposed reinforcing fibers which serve to reinforce a subsequently formed joint or boundary.
