Appl. No.:

10/708120

Inventors:

Jeremiah O. Salvatore - Redondo Beach CA, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

B64C 17/10

US Classification:

244135C, 244172

Abstract:

A method for operating a satellite () so that a predetermined amount of propellant is left to perform end-of-life maneuvers is provided. A first pressure differential is established between a first propellant tank () and a second propellant tank () by pressurizing the first tank () with a pressurant. Propellant is transferred from the first tank () to the second tank (). Using precise control during transfer the amount of propellant in the tanks may be determined. The second tank is used for orbit maintenance. The first tank is used for end-of-life maneuvers. Propellant may be transferred between the tanks using a latching process so that a predetermined amount of propellant may be transferred from a non-empty tank to a full tank.

International Classification:

H04L 9/26

US Classification:

726 1

Abstract:

A method and system for sharing data between networks comprises an interface for receiving data from plural inputs; a policy-based router operationally connected to the interface, the policy-based router assigns security levels to the data based on security characteristics of the inputs and the policy-based router assigns virtual Internet protocol addresses to the data; a memory for retaining the data with the Internet protocol addresses, the memory being operationally connected to the policy-based router; a translator for converting the data into a standard format; and a network stack for transmitting the data to a network. The method includes assigning security levels to the data based on security characteristics of the inputs; assigning virtual Internet protocol addresses to the data; retaining the data with the Internet protocol addresses; converting the data into a standard format; and transmitting the data to a network.

Appl. No.:

11/679486

Inventors:

Tuan A. Pham - Huntington Beach CA, US

International Classification:

G05D 1/00

US Classification:

701 4

Abstract:

An electronic flight bag (EFB) system for use on a mobile platform, for example, a commercial or military aircraft. The EFB system includes first and second independent processors that run first and second independent software applications. The first software application may be a Type C application requiring a high level of governmental agency certification for use on an aircraft while the second application may be a commercially available, off-the-shelf software application that requires no certification. The two processors share a common display, although the first processor is provided with control over the display so that use of the display by the second processor can be inhibited or limited by the first processor as may be needed to display more critical flight or aircraft related information. The first processor is also provided with control over a switching subsystem that can interrupt the flow of information from external I/O devices to and from the second processor, if needed.

Abstract:

An apparatus includes a bod, an actuation assembly, and a guide catheter extending distally from the body. The guide catheter includes an open proximal end, an open distal end, a rigid proximal portion, a bendable distal portion, and a pull wire extending from the bendable distal portion to the rigid proximal portion. A proximal end of the pull wire is coupled with the actuation assembly. The actuation assembly is operable to translate the pull wire relative to the rigid proximal portion to thereby articulate the bendable distal portion.

International Classification:

C02F 1/469
C01B 32/318
C01B 32/336

Abstract:

The present disclosure relates to a method for making a carbon aerogel electrode material. The method involves initially making a wet organic sol-gel form. The sol-gel form is carbonized at a temperature of from about 900 C. to about 1000 C., for from about 2 hours to about 4 hours. The carbonized sol-gel is then activated under carbon dioxide flow, for from about 0.5 hour to about 1.5 hours, at from about 900 C. to about 1000 C.

C02F 5/00

Abstract:

Use of porous carbon aerogel materials as capacitive deionization (CDI) electrodes to selectively remove scale forming divalent ions (e.g., Mg, Ca) from “hard” waters. A first electrode and/or a second electrode are made from activated carbon with graphite current collectors. A non-conductive, electrolyte permeable paper or polymer membrane separator is sandwiched between the first electrode and the second electrode.

International Classification:

C02F 1/469
C01B 32/318
C01B 32/336

Abstract:

The present disclosure relates to a flow through electrode, capacitive deionization (FTE-CDI) system which is able to adsorb nitrates from water being treated using the system. The system makes use of a pair of electrodes arranged generally parallel to one another, with a water permeable dielectric sandwiched between the electrodes. The electrodes receive a direct current voltage from an electrical circuit. At least one of the electrodes is formed from a carbon material having a hierarchical pore size distribution which includes a first plurality of pores having a width of no more than about 1 nm, and a second plurality of micro-sized pores. The micron-sized pores enable a flow of water to be pushed through the electrodes while the first plurality of pores form adsorption sites for nitrate molecules carried in the water flowing through the electrodes.
