Abstract: A technique for organizing a plurality of computers such that message broadcast, content searching, and computer identification of the entire collection or a subset of the entire collection may be performed quickly without the use of a controlling computer. The technique describes the creation, operation, and maintenance of a connection scheme by which each computer in the collection appears to be the top level of a hierarchical array. The maintenance of this hierarchical connection scheme allows one to many communications throughout the collection of computers to scale geometrically rather than linearly.

Abstract: A customizable garage door screen is disclosed that requires few components to deploy and store. Four elastic straps with hooks at each end are used with six grommets strategically placed on the screen for stability, and approximately one dozen screw and snap fasteners are installed around the perimeter of the screen and garage door frame for a tight enclosure to keep out pests. A partially oversized screen that can fit the average American garage door frame and requires little pre-fabrication effort is now possible with so few components. To open the garage door screen for egress and ingress, one simply unhooks one or both of the lower elastic straps, after unsnapping the desired number of end-caps, and latching upon the upper elastic straps or guide rails on either side. The elastic straps are also used to store the folded screen inside the top, backside of the garage door.

Abstract: An infrared (IR) security system and method is disclosed comprising two or more IR cameras directed upon a common surveillance area. Locations of the cameras and their optical fields of view are pre-established and stored in a central computer database. Computer programs harmonize the information into a 3D grid. The camera processors perform image processing on the surveillance area to detect moving objects. Object angular position, size, aspect ratio, and radiometric intensity are simultaneously transmitted to the central computer. The grid position, physical size, and inherent electro-magnetic contrast of the objects are computed. These IR signatures are then compared to the target definitions in the database of IR signatures on pre-defined threats. Alarm criteria can be based on object size, location, and movement over time. When a threat is determined, the user is notified by text message, image or video.
