Appl. No.:

10/172536

Inventors:

Kenneth R. Erikson - Henniker NH
George K. Lewis - Andover MA
Timothy E. White - Acton MA

Assignee:

BAE Systems Information and Electronic Systems Intergration Inc. - Nashua NH

International Classification:

A61B 814

US Classification:

600459, 29 2535, 310334

Abstract:

An integrated piezoelectric ultrasound array structure configured to minimize the effects of differential thermal expansion between the array and the integrated circuit and to improve the mechanical and acoustical integrity of the array. The transducer array may have an interposed thinned supporting substrate and is matched to the integrated circuit substrate for thermal expansion so as to retain mechanical integrity of the array/IC bond within the working temperature range. Transducer elements are laterally isolated acoustically and as to thermal expansion by air or other acoustically attenuating medium of lower elastic modulus material between the elements. Acoustical effects are vertically acoustically isolated with capacitive coupling and small area solder bumps relative to wavelength, and further laterally acoustically isolated by thin supporting substrates relative to wavelength, including thinned semiconductor integrated circuit substrates.

Inventors:

George C. Lewis - Sudbury MA, US

International Classification:

G01B 9/02

US Classification:

356500

Abstract:

A motion system includes a first stage that is configured to rotate about a first axis and a second stage coupled to the first stage that includes an object carrier adapted to position an object in at least one other axis. The motion system has a novel arrangement of laser interferometer elements and axes of motion. The arrangement permits accurate and precise measurement of a position of the object carrier in up to three (or more) axes of motion even as the first stage of the motion system is tilted through relatively large angles. The novel arrangement of the axes of motion also enables very precise control of the position of the object carrier even at high tilt angles.

International Classification:

G01F 23/28

US Classification:

73290V

Abstract:

A fluid detector includes a piezoelectric element that outputs a first ultrasonic signal in response to an input electrical signal and a lens with an upper portion and a lower portion. A housing is integral with an outer surface of the wall of a container and defines a cylindrical central bore for receiving the lens. The piezoelectric element is coupled to the upper portion of the lens so that the lens focuses the first ultrasonic signal toward the wall so that it enters the wall. An ultrasonic detector is disposed adjacent the outer surface of the wall, for receiving a second ultrasonic signal from the wall that results from the first ultrasonic signal and that is affected by the presence or absence of fluid. The ultrasonic detector generates an output electrical signal corresponding to the second ultrasonic signal.

US Classification:

73290V

Abstract:

A fluid detector for determining a presence of a fluid within a container includes a piezoelectric element that outputs a first ultrasonic signal in response to an input electrical signal and a lens with an upper portion and a lower portion. The piezoelectric element is coupled to the upper portion of the lens so that, when the lens is disposed adjacent the outer surface of the wall such that the lens is intermediate the piezoelectric element and the wall, the lens focuses the first ultrasonic signal toward the wall so that the first ultrasonic signal enters the wall.

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.

Abstract:

The method and apparatus for securing a lower garment over a garment wearer's stomach to keep the lower garment from drooping without the need to secure the lower garment to an upper garment or to require the need for a separate waist belt. An elastic belt with Velcro is connected to suspender clips which are attached to the lower garment before the garment is worn. When the lower garment is worn, the garment is pulled up with the belt suspenders and secured over the stomach, and when the wearer is comfortable, the Velcro is pressed together. The apparatus are designed to be worn under an upper garment that is not tucked into the lower garment. The benefits of this invention are that it holds up the lower garment without the need for traditional suspenders, and it provides the wearer with a more attractive appearance because the apparatus is covered by the upper garment and holds the stomach in, giving the wearer a slimmer look.
