Filed:

Aug 24, 2007

Appl. No.:

11/895385

Inventors:

George Lewis - Andover MA, US
Laurence Sanford - Tewksbury MA, US

International Classification:

A01K 1/02
A01K 29/00

US Classification:

119500000, 119028500

Abstract:

Animal health and wellbeing is of significance to our society, whether the animal is wild or domesticated. Many humans have practiced methods to secure animal interests in both their natural habitats and in modern day society/homes. The presented device is designed around these principles for the wellbeing and humane treatment of the animal, while it is being caged, crated, and/or kenneled. The invention is a portable unit that may be added/attached universally to the outside of any cage, crate, kennel or specialized porous animal pad, and provide air conditioning for the animal within the enclosure. The invention is powered by either a DC or AC supply, so it may be used in the home and on the road. The complete device conceived as “Kool Kennel” and/or “Kool Kushion”, consists of a thermoelectric Peltier Module used for cooling and/or heating the ambient air “The KK Module” along with various air diffusers to connect the regulated air to the animal crate or pad. The KK Module and air diffusers comes with Velcro mounting brackets, and a flexible insulating enclosure covering, to prevent heat exchange between the animal enclosure and surroundings.

Appl. No.:

6/656131

Assignee:

The Boeing Company - Seattle WA

International Classification:

G06G 770

US Classification:

364435

Abstract:

A wing camber command system (28) is provided for calculating the optimum camber of a wing (52) during aircraft operation. The wing (52) has at least one movable leading edge surface (42, 44) and at least one movable trailing edge surface (46, 48, 50) for varying wing camber, while maintaining smooth upper surface contours. Flight conditions and aircraft parameters including aircraft speed (30), normal acceleration (32), weight (34), and the dynamic pressure of air (36) are sensed during the aircraft maneuver. An onboard computer (40) monitors the sensed conditions and parameters and calculates a coefficient of lift therefrom. The computer contains stored data indicating the desired positions for the leading and trailing edge surfaces necessary to achieve a wing camber that optimizes the wing lift/drag (L/D) ratio during aircraft operation. The computer uses this stored data to command optimum wing camber.

Appl. No.:

7/111128

Inventors:

George K. Lewis - Andover MA

Assignee:

Analogic Corporation - Peabody MA

International Classification:

A61B 800

US Classification:

12866007

Abstract:

An ultrasonic medical imaging apparatus provides an ultransonic transducer constructed with polyvinylidene fluoride. Circuitry is included for generating an energizing pulse for the transducer, the pulse having a predetermined period and an instantaneous frequency which is varied from a first frequency to a second frequency during the period. Circuitry is provided for digitizing electrical signals from the transducer which electrical signals represent ultrasonic reflections received by the transducer in response to the energizing pulse, and a signal processor cross-correlates the digitized electrical signals with the energizing pulse.

Appl. No.:

6/781656

Inventors:

George E. Lewis - Renton WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

B64C 910

US Classification:

364463

Abstract:

A system for reducing wing root bending moment load during aircraft maneuvers. The system operates to reduce the lift on the outboard section of the wing by moving an outboard flap upward in response to commands calculated from aircraft parameters and a predetermined wing root bending moment load limit.
