Abstract: A breath transfer device which uses the heat of exhaled air to warm the body of the wearer of the device in cold environments, and which facilitates condensation of moisture in the device to eliminate the formation of vapor clouds. The device uses a mouthpiece into which exhaled air is blown, and a length of insulated tubing to direct the warm air to a vest-like radiating chamber garment. The moisture in the expelled air condenses on the inner surfaces of the chamber and is retained in special condensing pockets formed at the ends of internal partitions which provide a sinuous path for air flow through the chamber. Cooled dry air is finally exhausted at the lowermost point of the radiating chamber.

Abstract: A hinge assembly wherein the hinge pin and the first two of the interleaved hinge fingers are configured such that, once the pin has been installed and the hinge is in an operating position, the hinge pin is positively retained without the need for additional securing hardware.

Abstract: A continuous alignment system for preventing rotation of a missile during on-loading in a launching tube, while permitting a controlled translation of the missile in the launching tube when subjected to external seismic shocks.

Abstract: A safe/arm mechanism for an air-delivered explosive device uses a slider containing explosive leads as the means of interrupting the explosive train. The slider is locked in the safe position such that the explosive leads are out-of-line with respect to the detonator. The slider is attached directly to the main parachute such that when two locks are removed the parachute deployment forces can overcome a shear pin lock and move the slider to an in-line or armed position where it is positively retained. In this position, initiation of the detonator will allow the explosive output of the detonator to be transferred to its associated explosive device and provide a dual point radial initiation of its booster charge.

Abstract: A shock resistant missile longitudinal support assembly provides axial support to a canisterized missile while allowing the missile to translate under shock in any radial direction relative to the longitudinal axis of the canister.

Abstract: Apparatus for inhibiting transmissions from a remotely operated sensor system until its transmitter has been found to be free of two specific operative faults.

Abstract: A differentiating spatial light modulator device in which a photoreceptor and an electro-optic crystal are isolated by a dielectric mirror. The electro-optic crystal is configured to have low or zero longitudinal response, yet is sensitive to transverse electric fields. The fringe field generated by the photoreceptor (photodiode) modultes the crystal birefringence. Readout via a polarizing beamsplitter gives an output light related to the spatial gradient of the input light. In a liquid crystal embodiment of the invention, reversal of the applied voltage gives a driven off state which speeds the erasure. Storage is possible in the smectic liquid crystal phase.

Abstract: A method for distinguishing between multiple noise jammer sources having different noise spectral bandwidths. Noise signals are detected over a relatively narrow detection bandwidth. The percent of time that the jammer spectral noise is within the fixed detection bandwidth is used to estimate the jammer spectral bandwidth.

Abstract: A method for distinguishing between multiple noise jammer sources having different noise modulation bandwidths. Noise signals are detected by a receiver having a bandwidth substantially the same as the bandwidth of the jammer noise source. The dwell time of the noise pulses formed by the receiver provides a means for determining the noise modulation bandwidth of a noise jammer source.

Abstract: A method is described which provides automatic self synchronization (in time) between multiple pulse repetition frequency (PRF), pulse doppler radars. The synchronization technique time aligns data within a coherent look transmission (a group of pulses--typically milliseconds). This technique substantially eliminates sensitivity losses associated with blanking false alarms or detection from interfering radars transmitting (in time) at pulse repetition intervals (PRI) different than the host radar. An implementation of this method for a 2 PRF radar waveform is described although the technique may be extended to more than 2 PRF's. The technique provides an alternative approach to pulse shaping or multiple (different) frequencies to control MI but may be used in conjunction with these techniques to minimize sensitivity losses due to interference blanking. For applications where wide angular antenna beams are required and/or multiple simultaneous radar operation is required (e.g.

Abstract: A tool for isolating a printed circuit wiring trace from a component pin, said tool having a rotatable shank with an internal cavity and external cutting flutes formed on an end thereof. The end of the tool is pushed over the exposed end of the pin such that the cutting flutes bear against the solder material which bridges the gap between the printed wiring trace and the component pin. The tool is then rotated to remove the solder bridge and any underlying wiring trace material to isolate the wiring trace and pin from each other.
