Abstract: A method, apparatus and computer software for coding for tracks in a system is presented. At least one track of an object is determined on a detection display map, the track having an icon associated therewith. The icon is supplemented with a shape indicating additional information relating to attributes of the track, the shape providing perceptual visual awareness for an operator of said system. The shape includes an indicator of at least one of direction, velocity, path uncertainty, and a level of urgency of the track of the object.

Abstract: A media storage rack for storing a plurality of different media comprising an elongate media support base supported between first and second rack ends, the base defining elongate ribs and recesses sized and positioned to locate the plurality of media securely in the rack.

Abstract: A drawer interlock assembly for a furniture article having at least first and second drawers. A track member is positioned on the furniture article. The assembly includes at least first and second locking members slidingly mounted in the track member. The locking members are interconnected by at least one interconnection strip. Each of the locking members includes a locking projection. The assembly further includes at least first and second drawer members attached to the first and second drawers, respectively. Each of the drawer members includes a first ramp and a second ramp. Engagement of the locking projections with the first and second ramps allows only one drawer of the furniture article to be opened at a time.

Abstract: A file hanger kit, system and clips for mounting file hanging rails in a drawer on a tapered cross-section clip mounting rail running along the top edges of the drawer. The clips are formed in an upside down J configuration having a vertical portion and a generally C-shaped hook portion integral with the top of the vertical portion. The C-shaped hook portion defines and partially encloses a reentrant opening that faces down along the side of the vertical portion for hooking and wedging onto the tapered mounting rail when a downward force is applied to the clip by the files hanging on the rails mounted in the clips.

Abstract: A signal processor and method for maximizing the detection range of imaging infrared seekers against ship targets. The invention comprises a bank of two-dimensional spatial filters, having rectangular kernels matched to targets of various aspect ratios and sizes, implemented in a separable form that appears well suited to processing in real-time image data acquired sequentially by column.

Abstract: A beam-steering feed network for use with linear and planar phased-array enna systems which includes a phase divider system for producing a plurality of incrementally phased IF signals. The phase divider system includes a plurality of coupled amplifier phase divider modules coupled together to form a network. The network is coupled to receive at least two boundary signals having different phase angles. The phase angle difference between the boundary signals is divided by the phase divider modules in the network. Each module produces an output signal having a phase angle differing from that of the output signals of the immediately adjacent modules in the network by a phase angle gradient. The system thus divides the phase angle difference between the boundary signals into a plurality of incrementally phased output signals.

Abstract: A simple, relatively low cost system for sealing an ordinary roller shade with respect to the window frame sides, top and bottom is provided. The roller shade seal system essentially comprises a pair of edge seal assemblies in the form of elongate mounting strip members adapted to be permanently mounted to opposite vertical faces of the window frame trim, and a pair of sealing strip members in the form of elongate, generally U-shaped channels adapted to sealably engage the latter edges of the shade, releasably mounted to an associated mounting strip. The window shade sealing system is completed by a shade bottom edge seal comprising a rigid bottom strip reinforcing member, a sill sealing strip and a shade top sealing member.

Abstract: Optical channel waveguide switches/modulators having polarization-independent operation are disclosed. Electrodes are disposed in proximity to the waveguide channels to provide an electric field that is primarily horizontally directed in at least one channel and an electric field that is primarily vertically directed in at least one channel. Since the different electric-field orientations electrooptically induce different changes in the index of refraction for waves of different polarization in the guides, this permits improved electrooptic control over both TM-like and TE-like modes. Embodiments of both modal interference switches/modulators and branching waveguide switches/modulators are disclosed.
