Abstract: A multiple field of view dual band optical device with integrated calibration source is disclosed. Such an optical device is modular, and has a rotating electro-mechanical “tumbler” which houses two orthogonal Galilean afocal optical assemblies as well as at least one uniform temperature source. This modular device is intended to be inserted in front of a camera system which already has an imager optical assembly mated to a detector focal plane array. The disclosed modular device thus serves the purpose of providing to an existing dual-band camera imager up to four new optical fields of view as well as an integral calibration source, all of which can be electro-mechanically selected for viewing by a host camera imager.

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 optical system is provided for a FLIR mounted in a cylindrical turret ch has five folding mirrors, two doubling as scanning mirrors, numerous lenses with aspherical surfaces and different refractive indices, and a rotatable head mirror. Some of the lenses and mirrors being mounted on remote controlled electrically powered focusing or scanning means.

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. The resolution is more than doubled by using a narrow two dimensional array of Hg-Cd-Te detectors with pn junctions as a time-delay-integration line sensor, improved optics and analog-digital conversion with image enhancement.

Abstract: A medical electrode having a resilient terminal press fit onto an eyelet. The eyelet is plastic and has a conductive coating thereon. The terminal is made of a resilient nonmetallic composition, such as a polypropylene blend loaded with carbon fiber. An electrolyte composition is spread upon the bottom of the eyelet for making electrical contact with the skin of a patient. The eyelet, the terminal and the electrolyte composition are preferably all at least translucent to x-rays.

Abstract: A wheeled article of luggage comprising a wheeled frame and a garment bag mounted on the frame. The frame comprises a generally rectangular base, one of the long edges of the base constituting the front edge of the base and the other long edge constituting the back edge of the base, and a post extending up from the base closely adjacent the back edge of the base generally at the center of length of the base, for hanging garments on hangers in front of the post. The bag has a bottom, front, back, sides and a top. The bag bottom is of a generally rectangular shape corresponding to the shape of the base and is secured to the base. The front of the bag extends up from the front edge of the base and is openable for access to the interior of the bag. A bracket is cantilevered forward from the upper end of the post, carrying a rod. A handle is attached to the bracket extending on the outside of the top of the bag arranged for pushing the wheeled bag in direction lengthwise of the base.

Abstract: Carbon black is produced from a pyrolyzed hydrocarbon wherein pyrolysis is effected by combusting a synthesis gas containing hydrogen and carbon monoxide. The synthesis gas is produced from reforming a hydrocarbon fuel, wherein the reformation is heated by combusting carbon black effluent tail gas or indirect heat exchange of the hot tail gas.

Abstract: The disclosure is a dual controlled linear resonance cryogenic cooler and comprised of a remote cold finger and a compressor, both driven by linear motors. A motor control means is used with the linear motors to drive both motors with a phase delay of the cold finger motor from that of the compressor motor such that the compressor linear motor alternately drives a piston to produce alternating pressure waves in a light cooling gas in working relation with a regenerator-displacer in the remote cold finger and the cold finger linear motor has a delayed phase relationship with the compressor linear motor. The use of linear motors which are slightly out of phase with each other selectively provides flat top and bottom dead center with constant linear increases and decreases therebetween for the compressor piston to follow and to eliminate the normal side forces of the piston that cause excessive wear.

Abstract: A means for producing an optimized cooler expander waveform for a closed le cryogenic cooler. The cooler displacer is driven by magnetic and spring biasing means through four repeated phases of each cycle to produce four portions of the optimized cooler waveform in which each portion takes up about 25% of the total cycle. The portions are comprised of a constant velocity in opposite direction and dwell times with smoothed corner transitions between each portion. Control means for controlling the displacer movement to produce the specific waveform may be provided by a function generator applying the desired waveform into a displacer control drive circuit which has as a second input a sensory signal of the actual position of the displacer.

Abstract: A system for the remote monitoring of vending machines and for automatically communicating conditions at the vending machines to a central computer complex is described. Each vending machine is provided with a microprocessor which monitors and stores data within that machine and transmits the data to the central computer complex either immediately or at scheduled call-in times. The distributed logic between the vending machine microprocessors and the central computer complex provides various alarm function signals and aids in inventory control and efficient route planning for the supply and maintenance of the machines. In a preferred embodiment the data is transmitted between the central computer complex and each vending machine over telephone lines.
