Abstract: Provided a system and method for detecting an event while discriminating against false alarms in a monitored space using at least one sensor suite to acquire signals, transmitting the signals to a sensor system device where the signal is processed into data packets, transmitting the data packets to a data fusion device, where the data packets are aggregated and algorithmic data fusion analysis is performed to generate threat level information. The threat level information is distributed to a supervisory control system where an alarm level can be generated when predetermined criteria are met to indicate the occurrence of an event in the monitored space.

Abstract: The invention relates to a method for determining the position of a mobile object by using at least one radio signal having a rotating transmission characteristic with at least one reference station. The relation between the orientation of the transmission characteristic and reference events is communicated to the mobile object. The orientation of the transmission characteristic and the relative position with respect to the reference station can be determined from the reference event.
