Abstract: The present invention provides systems for analyzing URL lookup requests that are malformed or otherwise fail to provide an adequate response, and providing content-relevant results for those requests. The systems and methods rely on analysis of URL requests and on logical assumptions based on common errors in submission of URL requests. A weighting system is applied to portions of failed lookup terms to provide improved relevancy for results based on those failed lookup terms.

Abstract: The invention provides methods of creating and using objects that are detectable in the infrared range of the electromagnetic spectrum. The objects typically have two or more removable elements that are detectable using infrared sensing equipment. The detectable elements are removable from the object for rapid part renewal in the field of use. Particular application is made to the use of such for combat identification.

Abstract: An elongated strip of release paper supports infrared reflective tape releasably attached to the backing paper. The infrared reflective tape is cut to form segments that can be dispensed like labels that can be held in place by an adhesive backing to enable the segment of reflective tape to be sewn in place on a garment. Infrared reflective segments can be dispensed from a roll on a spool using a manual label dispenser.

Abstract: A communication system and method utilizing an infrared signal emitter communicating a predefined signal, and an infrared signal receiver capable of receiving such predefined signal, distinguishing such predefined signal within a field of view of the infrared signal receiver, and providing output indicating the location of the infrared signal emitter within the field of view of the infrared signal receiver.

Abstract: A marking system that allows remote observations of visual and infrared electromagnetic signatures emitted from a distinctive marker panel. A kit employing such panels is particularly suitable for military environments, which, in turn, enhances the survivability of military equipment. The marking system preferably provides a signature in the mid and far infrared and near infrared portions of the electromagnetic spectrum, such that the electromagnetic radiation can be observed by a pilot in an approaching moving object such as a plane, helicopter, or land vehicle that is equipped with a thermal imaging system or light intensifier device, even in adverse environmental conditions. In varying embodiments, the marking system may be used as a landing marker, a bore sight panel, and an identification panel. Utilization of passive infrared material enables use of such marking system when external power is unavailable.
