Abstract: A near infrared illuminator for enhancing viewing of a target viewed with infrared viewing device when the target falls within a predetermined range. A pulse generator generates a laser pulse in the near infrared with a pulse clock for control of laser brightness and a pulse frequency adjust for control of laser blink rate. The pulse is transmitted along an optical path at a specific brightness and blink rate to a target. A detector within the optical path detects a reflected infrared signal from the target and converts the signal to an electrical signal which is processed by a processor to obtain target range information. A trigger logic controls the pulse clock rate means whereby when the target range falls within a predetermined range the laser pulse rate is increased such that increased illumination of the target is viewable with an infrared viewing device.

Abstract: A method of producing an energetic composition comprising the steps of (a) issolving an alkali metal hydroxide in aqueous denatured alcohol to form an alcohol and alkali metal hydroxide solution; (b) kneading phenolphthalein or other reaction product of a phenolic compound and phthalic anhydride with sulfur, potassium nitrate and said alkali metal hydroxide solution formed in step (a); (c) allowing the kneaded product formed in step (b) to dry through evaporation of the aqueous denatured alcohol; (d) granulating the dried product formed in step (c); and (e) further drying the granulated product formed in step (d). An alternate method is also disclosed in which an alkali metal salt of phenolphthalein is used so as to avoid use of the alkali metal hydroxide in the aqueous denatured alcohol. Granular products are disclosed and closed bomb test results are presented. Certain products match the performance of commercial black powder.

Abstract: A method is provided for the integration of a low-volume liquid flow and ing system and a portable optical waveguide-based fluorescence detector for the chemical analysis of reagents in fluorescence-based reactions. The method is particularly applicable to the detection of enzyme inhibitors, modifiers, or ligands in cases where a fluorescent enzyme substrate or product exists. In a preferred embodiment, the presence and concentration of acetylcholinesterase inhibitors, such as chemical warfare nerve agents or certain insecticides, is determined by mixing aqueous samples with a dilute solution of n-methyl indoxyl acetate, and monitoring the formation of a fluorescent product (n-methyl indoxyl). The presence of an acetylcholinesterase inhibitor reduces the amount of fluorescent product formed in a given time period.

Abstract: A voice channel remote control system for operating remote smoke generators or battlefield operations. The system includes a transmission end for sending a voice channel signal and a receiving end for receiving and acting on the signal. A tone generator for sending a tone signal of a least one tone digit from the transmission end is included. Also included is a microphone at the receiving end for receiving the tone signal. A tone decoder is operably connected to the microphone pickup, with the decoder being adapted to validate and decode the tone signal to provide a binary coded decimal output for receiving the tone signal to thereby provide a coded decimal output. This output is connected to a decoder/driver which transforms the decimal output to provide a driving signal. Finally, a relay receives the driving signal and transmits an activation signal to thereby activate the remote smoke generator device.

A foam rubber seal, mounted on the inside surface of the hood, is located on the periphery of the face piece. An pair of eye pieces are mounted on the face piece for permitting exterior vision from inside the hood. A plurality of filter cells with flexible charcoal filters are mounted on the bib. Air ducts extend from an air reservoir fed by the cells to the face piece to permit filtered air to be drawn into the face piece. A flapper valve is mounted on the face piece to permit air to be exhausted from the mask.

Abstract: Form-fitting, comfortable, soft-shell protective apparel, commonly called a as mask, for protecting the head, upper body and respiratory tract from chemical/biological agents and toxins and radioactive particles. A unitary, easy-to-put-on, heat and moisture-dissipating multi-layer construction enables prolonged use and internalizes an adjustable suspension system as well as the purified breathing-air path. The latter is structured to enable the self-contained purifying agent to be located away from the face for facilitating weapons compatibility and reducing fatigue. Goggle-like eye lensing is designed to minimize eye relief and maximize peripheral vision and look-down capability, while providing optical correction and laser-light protection. The mask design minimizes dead space leading to distortion and other communications problems, and enables purifying-agent changes in a "hot" environment.
