Abstract: A fire suppression system includes a high pressure inert gas source that is configured to provide a first inert gas output and a low pressure inert gas source that is configured to provide a second inert gas output. A distribution network is connected with the high and low pressure inert gas sources to distribute the first and second inert gas outputs. A controller is operatively connected with at least the distribution network to control how the respective first and second inert gas outputs are distributed.

Abstract: A programmable controller for a fire suppression system includes a rewritable memory module and a processor module as well as multiple sensor inputs and control signal outputs.

Abstract: A system comprising a plurality of three dimensional artificially animated portraits for performing preprogrammed animations of voice and facial expressions in the form of a scripted dialogue orchestrated by a central source. The system is operable to prepare animations of recorded voice and selected depictions of facial expressions to be transferred to the animated portraits and performed by the animated portraits. The system is operable to combine prepared animations in a scripted dialogue to be performed so as to mimic an interactive conversation.

Abstract: An electronic system, for use at a facility, to immediately display notification, at a plurality of locations within the facility, that a person is missing. The system includes a portable data storage medium containing information related to a person, including an image of the person, to be carried by a guardian. The system also includes a network of stations and a system server equipped to receive the data from the portable data storage medium, in the event that the person and the guardian are separated, and to display an image of the person at a plurality of stations to assist security personnel and bystanders in locating the person. The invention also includes a method of recording information related to a person on a portable data storage medium and providing a network of stations and a system server to receive information including an image of the person and to display the image simultaneously at a plurality of locations.

Abstract: Disclosed is a fire detection and engine monitoring system of the type which utilizes a pair of elongated thermistor strands extending over substantially the same path to provide redundancy. A resistance of the two thermistor strands are sensed and a resistance difference signal is generated. The resistance signal is monitored for abnormal differences between the two identical thermistor devices which are essentially exposed to the same operation conditions. Such differences are indicative of the deterioration over time of the condition of one of the sensors.

Abstract: A telephone switching system and method eliminates the need for high speed computers by employing a master controller having its own microprocessor to coordinate and control a tone controller, a switch controller, and a coupler controller, each of which has its own microprocessors and performs independent parts of the overall system control function. The master controller microprocessor interacts with each other controller microprocessor via a communication bus to segment the control functions into small independent operations which may be performed simultaneously. System call handling capacity can be increased by adding modular controller units to service added telephone lines. A solid state fully protected voice coupler is protected against voltage and current surges while meeting all relevant FCC specifications for connection to any voice transmitting and receiving equipment.
