Abstract: A system and method for monitoring an alarm system at a premises is described. The alarm system includes sensors to detect one or more alarm conditions at the premises. In response to an alarm condition, an alarm signal is sent to a gateway. In response to the alarm, the gateway retrieves location of associated users of the alarm system and location of the premises and sends the alarm condition and the location information to a monitoring center which receives the locations of the associated users of the alarm system and the location of the premises from the gateway and determines a response to the alarm based on the locations of the associated users.

Abstract: A system method for improving the accuracy of a tracking device is described where the tracking device cannot achieve an accurate GPS fix due to low observability. The system and method improves accuracy determining a current position for the tracking device using incomplete information from the GPS. The current position is added to a historical table of previous position determinations and a normalized center position is calculated from the current position and previous position determinations. The position of the tracking device is inferred from the normalized center position.

Abstract: A system for redundant delivery of fire suppression event data is described that includes a sprinkler system connected to a plurality of sprinkler heads through riser pipes used to carry a fire suppression medium, wherein the sprinkler system includes an event reporting interface. An alarm event reporting system is connected to the sprinkler system using the event reporting interface, where the alarm event reporting system has a first communications interface and a second communications interface. The alarm event reporting system communicates with a central monitoring system using the first communications interface or the second communications interface, such that communications between the alarm event reporting system and the central monitoring system are maintained in the event of a failure in one of the communications paths.

Abstract: An adaptor for remote coupling a security system to a monitoring center is described. The adaptor includes both a wireless connection to an alarm panel and a remote wireless interface. The wireless connection to the alarm panel is configured such that the adaptor appears to the alarm panel as a control pad. The adaptor communicates with a central station using the remote wireless interface and is operable to translate messages between the alarm panel and the central station into an appropriate protocol.

Abstract: A mobile station connected to a wireless network can comprise a subscriber identity module. The subscriber identity module can maintain a list of networks. The list can comprise forbidden public land mobile network data. Software can manage the forbidden public land mobile network data. For example, an applet transmitted to the subscriber identity module can periodically delete entries from the list and/or reset the subscriber identity module on predefined time intervals or when specified events occur.
