A weapon receiving cradle includes a compressive, elastomeric pad and surfaces conforming to the aft end of the weapon and the marksperson's hand and/or shoulder. Cant adjustment means are provided at the shock plate, windage adjustment means couple to the longitudinal frame and a resilient strap can be used to further couple a weapon to the assembly.

Abstract: A method and apparatus for recording prints of digital extremities, and the like, utilizes a transparent print indicia recording medium to record images corresponding to the digits of an individual wherein the record, thus obtained, on the adhesive coated surface of the transparent medium may be sealed to a transparent base and then utilized to generate a plurality of image displaying records which may be easily disseminated and used by others in various postures and manners, e.g., front or back observation of a digit indicia as well as transporation or communication of reproductions of the original records to remote locations and/or storage in typical memory devices such as magnetic tape or the like.

Abstract: A relatively large dimensioned sputter coated resistive laminate providing uniform laminate dimensions and resistance tolerances over the surface area thereof and a method for making the laminate from a foil, including a platten support step and a sputter etching or cleaning step. The laminate comprises a sputter coated metal foil which is isostatically bonded to an insulative, epoxy resin substrate. In a preferred construction a nickel-chrome-aluminum-silicon resistive layer is applied to a copper foil.

Abstract: A flexible laminated delay line assembly formed to include a plurality of patterned regions which may be folded into sandwiched relation to one another without affecting electrical continuity. The transmission line layer is laminated between successively adjacent dielectric and ground plane layers. Windows cut into the ground plane and dielectric layers facilitate folding and decoupling of a support spine, folding of the conductor sections and sizing of the assembly. In one construction, the dielectric layers comprise a flexible insulative substrate laminated between upper and lower thermoset layers. In another construction the dielectric layers comprise a polyetherimide that is melt flowed about the pathways of the transmission line.

Abstract: A retainer for supporting an injection molding machine ejector bar. The retainer is mounted to a hydraulic ram and secures an ejector bar in clamped relation relative to an extractor pin assembly secured to a molding die. The retainer includes a relatively large self-aligning cavity wherein an ejector bar end is confined via a transverse mounted jaw having a ridged gripping surface that interconnects with an annular slot formed in the ejector bar.

Abstract: Apparatus comprising a vehicle mounted support coupler, an upright stanchion and an accessory support platform. In combination, the stanchion is mountable to a vehicle chassis or seat for advantageously supporting accessory items relative to the operator, yet permitting selective removal when not required. Liquid drinks and sundry other items are supportable from the stand.

Abstract: A portable sleep monitoring system for recording on tape, transcribing and charting a plurality of physiologic data channels recorded relative to a known constant, user-transparent time base. Selected ECG, air flow, impedance and pulse oximetry sensor inputs are recorded under microprocessor control relative to a crystal controlled 40 Hz signal modulated with the physiologic data from one of the sensors. Upon reading the physiologic data from tape and/or charting, the collected data is displayed with the time base, normalized to the known crystal controlled timing signal. In the heart rate mode, QRS occurences are displayed on the heart rate trace line as singular hash marks. The presence of motion at the pulse O2 sensor is indicated by multiplexing high frequency hash markings onto the O2 saturation trace line. Calibration levels relating to four different O2 saturation percent vales are periodically written to tape for reference during tape reading.

Abstract: A nesting rim member mountable in circumscribing composite relation to the stacking end of a walled container. The rim includes an outer vertical flange portion which tapers inward from an upper edge to a nesting ledge. An inverted U-shaped channel portion beneath the nesting ledge extends over the container sidewalls which are recessed at their corners to receive pronged corner clips, if necessary. Each clip mates with the rim member when pressed onto the container walls. A U-shaped channel orthogonally projects inward of the container. The rim member may be extruded and pieced to the container walls or molded as a continuous ring.

Abstract: A security alarm network including a plurality of microprocessor-based, subscriber system controllers, wherein each controller is capable of responding to a plurality of distributed wireless and hardwired sensors/transducers and is programmable via user, central station and installer-entered system and network parameters.

Abstract: Clothing items including at least one sewn-in liquid cushioned bladder conforming to one or more pressure points experiencing friction or repeated shocks. Distributed through vents and sealed islands define one or more endless channelways to facilitate moisture transfer and assure even liquid distribution with body movement. Associated vented, wicking coverings transfer perspiration away from the bladder and wearer. Preferred embodiments include pantswear, gloves and an improved bladder containing seat cushion.

Abstract: A two-sided thimble including an elastic fitting member and a hand pull flap. A first envelope surface permits fine needle work and a second surface including a contained rigid protective member facilitates heavy duty needle work. In an alternative construction, each surface may accommodate either heavy or fine needlework.

Abstract: Multi-layered, thick/thin film, nanosecond delay lines, the inductive/capacitive characteristics of which are tailored to provide line impedances yielding unit delays of 1 to 10 nanoseconds. The delay lines are constructed on a supporting ceramic, resin/fiber or plastic substrate. In alternative embodiments, a serpentine conductive layer of tailored line widths and conductor spacings is sandwiched relative to overlying dielectric layers of 25 to 200 microns thickness and associated ground plane layers. In another embodiment, multiple conductor layers are sandwiched relative to intervening dielectric and ground plane layers. Lateral contact pads/pins, vertical vias and jumper conductors permit circuit connection and interconnection of the layers.

Abstract: A knotless cordage coupler for releasably securing a pair of cord ends to one another. The coupler in one construction comprises a planar member including a pair of rope end receiving apertures formed along a longitudinal axis of the member. A plurality of staggered wedging notches extend inward along the peripheral edges of the coupler to receive a wrapped cord end and maintain the rope ends in secured parallel alignment with the longitudinal axis. In another construction, a tubular body includes opposite wedging notches and an open flange for receiving the tag end.

Abstract: A rigid ceiling system including a plurality of gridwork members supported solely from the walls of a room and further including a plurality of vaulted translucent diffusion panels. Notched rib members including indexing brackets align each panel to the formed gridwork. Wall mounted illumination sources provide desired lighting relative to the diffusion panels.
