Abstract: An apparatus determining network health comprising base stations in bidirectional communication with radios, each having an identifier and transmitting a signal including the identifier. First and second health determining devices each receive the signal during normal over-the-air operation of radio and determine if the radio is authorized and, if so, determine the identifier, time-separated signal waveforms that are compared, operating characteristics from the compared waveforms, and a current location of the radio. Each of the devices determine health of the radio based on packet sniffing, a frequency deviation, or a range of deviations by analyzing the operating characteristics. After analysis results sent to the master controller from the devices indicate that the authorized radio is healthy, the master controller determines from the analysis results that a geographically unhealthy location of the network exists within the geographic area from which the authorized healthy radio transmitted the signal.

Abstract: The present invention is an improved method for decontamination of a space and an integrated device that completes the decontamination cycle extremely fast while still being compact, lightweight, simple to operate and easy to move as a single unit. The method of the present invention delivers less biocide than is used in prior art methods at a very high rate of flux, allows the biocide to reside in the space being decontaminated to achieve a predetermined kill level, and then aerates the space. Because a nominal amount of biocide is used, there is less biocide to remove from the space than in prior art methods thereby reducing the time required for aeration and shortening the downtime for safe entry of the facility.
