Abstract: A system and method for identifying whether a communication in a computer network is directed to a destination that is internal to a company includes receiving destination information associated with a first network communication. The computer network includes a directory server, which includes a company directory that provides employee information. The directory server is accessed, and the received destination information is compared with information in the company directory. It is determined whether the first network communication is directed to a destination that is internal to the company based on the comparison of the received destination information and the information in the company directory.

Abstract: A system and method of installing components of a software product on a first network server device coupled to a network includes automatically detecting with the first network server device a first set of server-assisted network devices coupled to the network that are eligible to use a first service. The components of the software product provide the first network server device the capability to provide the first service to a plurality of server-assisted network devices coupled to the network. Device information based on the detected server-assisted network devices is automatically transmitted to a second network server device. License information is received from the second network server device based on the transmitted device information. Components of the software product are automatically installed on the first network server device.

The digital sender service comprises, for example, logic to map from a number of destination addresses to a respective number of security identifiers, and, logic to add a number of access privileges to the digital document via a network using the security identifiers. The digital sender service also includes logic to post the digital document on a server accessible via the network. In addition, the digital sender service includes logic to generate and transmit a number of email messages to the corresponding number of destination addresses on the network. The email messages include a uniform resource locator of the digital document on the network.

Abstract: FLIR kits are provided comprising optical and related components which can be commonly used for both navigational and targeting scenarios. Such components include a common detector interface, imaging optics, scanner, interlacer, filter wheel, and thermal reference sources with integrated chopper/rotator assembly, all of which when assembled form a stand-alone imaging sensor when combined with a common associated electronics subassembly. The kits are integrated into standard navigational and targeting platforms of the type found on the AH-64 Apache and RAH-66 Comanche attack helicopters.

Abstract: An opto-mechanical configuration for direct laser scanned retinal imaging is described. The concept uses simple geometric properties of an ellipse in a reflective optical delivery system which allows a small scanned laser beam to create a two dimensional video image directly on the retina of the human eye. The system is best suited for use in head-mounted display applications where light weight is a priority.

Abstract: An optical assembly and technique for magnified viewing which includes innal damaging laser energy protection. An objective lens subassembly is positioned on the focal axis which focuses incoming light energy over an entire field of view. An optical prism accepts the focused light energy and reorients the focused light energy which is split by a beamsplitter onto a power limiter at the intermediate focal plane so that only energy under an approximate damage threshold is allowed to pass onward. The optical assembly can provide from 4.times. to a 10.times. power magnification with up to a 60 millimeter entrance pupil diameter with internal, multi-spectral damaging laser energy protection.

Abstract: An optical assembly using a centrally-obscured catadioptric optical objece that provides two different focal planes using the same set of optics. Both optical paths share the same optic axis and common line-of-sight. One focal plane is optimized for use with a high performance GEN II image intensifier tube, and the other is used for either laser receiver or emitter devices.

Abstract: A head-mounted vision enhancement system which provides crash survivabili weight, and center of gravity superior to the currently fielded image intensifier goggle arrangements. This is accomplished by positioning the goggle objective lens assembly and intensifier tube closer in around the head and then using an eyepiece to bring the image back around into the eye. Hypersteropsis is thus avoided by folding the intensifier objective lenses from the center of the forehead.

Abstract: A pressure balanced brake disc stack provides brake discs of greater thickness at the ends and center of the stack and of a lesser thickness at the areas in between the centrally disposed disc and the discs at the end of the stack. The increased thickness of the discs at the end of the stack prevent deflection or distortion of those discs to more evenly distribute the braking pressure applied thereto throughout the stack so as to provide a higher braking coefficient. Additionally, the unique configuration of the brake stack allows for effective heat dissipation at the discs adjacent to the end discs of the stack.

Abstract: An improved modular FLIR system is provided that fits in the same space elopes that were provided for the Army's GEN I FLIR's.

Abstract: An objective lens assembly provides up to 60 degrees field of view for the NVIS image intensifier goggle. A first lens subassembly positioned on the focal axis faces a external view and substantially corrects pupil aberrations in an aperture stop located after the first subassembly. A second lens subassembly is then located after the aperature stop on the focal axis. Color and field aberration corrections is provided while maintaining substantially high quality focus by a third lens subassembly. A lens element after the third lens subassembly on the focal axis flattens the image plane over the intensifier image format such that there results a format of up to 25 mm with a photocathode resolution for up to a 60 degree field of view.
