The present invention provides a true-scale, coordinate-matched, linked in real-time, dual three-dimensional/two-dimensional visual display/viewer. The display simultaneously shows a 3D digital image and an associated 2D digital image of a selected drawing. The display of the present invention allows a user to visualize an asset's location, surrounding environment and hazards and true scale structural details for interior or external structural scenes. Using the display and associated tools, the user can obtain real-time information of an environment, true-scale measurement, plan ingress/egress paths, shortest paths between points and the number of doorways in a structure and track objects within the displayed environment. The intelligence gained using the tools and 3D/2D display may be used and further manipulated by a single user or may be distributed to other users.

System and method for simultaneously viewing, coordinating, manipulating and interpreting three-dimensional and two-dimensional digital images of structures for providing true scale measurements and permitting rapid emergency information distribution

A unique digital compression technology for increasing the information carrying capacity of a bandwidth limited communications path highway by using a combined coding and modulation technique. The inventive technology allows multiple independent modulated data streams to simultaneously and instantaneously share the same bandwidth without cross-channel interference. A matched filter is used to substantially reduce the error rate and utilizes a unique training method based on performing a spectral response test. An algorithm calculates the effect of the unique characteristics of the communications highway on the transmitted signal and generates an ideal signal stored in the matched filter for comparison with received signals.

Method and apparatus for increasing the channel capacity of a bandwidth limited communications path

A digital compression system including a superresonant filter, which adds samples of a digital data signal at a frequency to previous samples. The added samples are parts of sine or cosine waves, not the sum of the waves. The output signal is actually the summation of the samples. The samples are made during at most a single period. The disclosed superresonant filter has a settling time significantly faster than prior art narrow band filters. Prior art narrow band filters passing approximately 1 Hz require approximately 1 second to settle. The disclosed superresonant filter passing 1 Hz will settle in approximately 1 microsecond.
