Filed:

Oct 25, 1999

Appl. No.:

09/427195

Inventors:

Henrik T. Jensen - Los Angeles CA
Joseph F. Jensen - Malibu CA

Assignee:

HRL Laboratories, LLC - Malibu CA

International Classification:

H03M 166

US Classification:

341144, 341143

Abstract:

A method and apparatus for digital-to-analog conversion utilizing randomized dynamic element matching for the attenuation of harmonic distortion during the conversion process due to non-ideal circuit behavior is presented. The present invention introduces a new DEM approach that results in a simplified DAC architecture relative to previous DACs, while preserving optimal spurious-free dynamic range (SFDR). The particular topology utilized involves the use of a bank of DAC-elements, preferably 1-bit DAC elements, the outputs of which are summed to yield a single multiple-level DAC. During each conversion cycle, random selection is used to determine the addresses of the DAC-elements used in order to âscrambleâ the DAC noise arising from each individual 1-bit DAC.

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

F28F 13/00

US Classification:

165135, 1651341, 165 82

Abstract:

A heat exchanger for transferring energy from a second fluid to a first fluid has a plurality of tubes to carry one of the fluids and a layer of thermal buffer members on one side of the tubes to act as a buffer to reduce high thermal stresses that may be caused by global temperature patterns and localized high gradients that occur in system transients such as start up and shutdown. Conventional heat exchangers often have a short lifespan due to high thermal stresses acting on the core of the heat exchanger. The heat exchanger uses the thermal buffer members as an increased thermal mass to cause the temperature of the heat exchanger core to change in a more gradual manner, thereby reducing thermal stresses.

International Classification:

B01D 45/12

US Classification:

55396, 55397, 554342, 55456, 55457

Abstract:

An environmental control system (ECS) for an aircraft may be employed to regulate temperature of air entering a cabin of the aircraft. During conditioning of the air, condensate may form in the air. A multiple-stage condensate extraction unit may be incorporated into the ECS to remove the condensate. The extraction unit may be provided with two fluid collection stages built into a cylindrical duct. The duct may have a bend therein. One of the collection stages may be positioned on an upstream side of the bend while the second one of the stages may be positioned on a downstream side thereof. The combination of the two stages and their positioning on either side of the bend may provide a particularly compact and efficient condensate extraction unit.

Appl. No.:

12/052889

Inventors:

Joseph M. Jensen - Torrance CA, US

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

F28D 17/00

US Classification:

165 10, 126400

Abstract:

A two fluid thermal storage device that may allow for independent heating and cooling includes a plurality of plate members with a set of dividers brazed between two of them. The set of dividers, which may define a series of passageways therein, may include a first sub-series of alternate passageways filled with a phase change material, and a second sub-series of remaining passageways that transports a fluid, the remaining passageways alternating between transporting a cooling fluid through a first fluid circuit and transporting a heating fluid through a second and independent fluid circuit. The remaining passageways that transport the cooling fluid through the first fluid circuit are defined by a first subset of dividers and the remaining passageways that transport the heating fluid through the second fluid circuit are defined by a second subset of dividers.

US Classification:

416245R, 416244 A, 60 3908

Abstract:

A nose cone of a turbomachine, such as an aircraft engine, is heated to prevent ice formation. The nose cone is configured as a conical shell positioned concentrically over an inner shell with a space therebetween. Spiral spacers in the space provide distributed passages through which heated lubricating oil flows. A system for separating entrained air from the lubricating oil as part of this mechanism is disclosed.

Abstract:

An analog-to-digital converter 10 employs a series of comparators 12, 14, 16 and 18. Each comparator includes at least one inverter consisting of a CMOS transistor pair including a P-channel transistor 22 and N-channel transistor 24.
