Abstract: A stackable modular building enclosure assembly and system including in combination a plurality of prefabricated substructure frames superposed, one above the other, and a combined connection tie and frame reinforcing sustainer member for constructing straight, angled or arced building enclosures including walls and roofs. In a preferred embodiment of the invention, prefabricated substructure frames include preinstalled interior and exterior facer members and utilize a hollow cavity to easily accommodate a hidden locating means for receiving a distinct tie and sustainer element.

Abstract: The time difference of arrival for a signal received at two or more receiving sites as transmitted from a wireless communications device, is determined by a frequency domain technique. The constituent frequencies of the signals received at the two or more receiving sites are determined, including the phase, or a value representative of the phase, of each frequency component. The phase values for the same frequency are subtracted to yield a phase difference values as a function of frequency. The slope of the function represents the time difference of arrival for the wireless communications device signal as received at the two receiving sites. To determine the mobile location based on the determined time difference of arrival values, a seed or initial location is first assumed for the wireless communications device and the distance difference of arrival (the time difference of arrival multiplied by the speed of light) is calculated.

Abstract: A data check tool useful for processing drive test data for assessing performance of a communications system. After (or during) test data collection, the data check tool processes the test data to determine whether the collected test data meets the requirements of a previously identified list of desired test data. The tool also determines whether the test data was collected using the correct test equipment and whether the test equipment was properly configured during the data collection process.
