Abstract: A thermally-enhanced, insulated component for use with an HVAC system includes a component having an outer surface usable with an HVAC system, the component being substantially filled with an insulating material. A thin, dimensionally stable layer of thermal barrier material having opposed surfaces is disposed inside the component at a predetermined distance from the outer surface of the component. The thermal barrier layer is in contact with the insulating material on at least one surface of the opposed surfaces. When the outer surface of the component is subjected to an elevated temperature, the thermal barrier layer maintains a sufficient temperature differential between the surface of the opposed surfaces of the thermal barrier layer facing opposite the outer surface and the surface of the opposed surfaces of the thermal barrier layer facing the outer surface so that the insulating material produces a reduced rate of smoke.

Abstract: A method of processing a timing synchronization signal includes selecting an initial sequence of complex numbers and modifying the initial sequence based upon a metric applied to the autocorrelation function to enhance its autocorrelation properties within a predetermined window about the main autocorrelation peak determined by the timing uncertainty of the system. This two-step optimization process produces a new complex sequence used for timing acquisition. It is applied by transmitting the sequence through a medium and correlating the received signal against a known error-free sequence. Only correlation within the window of the bounded timing uncertainty is performed, thus saving valuable computational cycles. Also, because the sidelobe levels of the autocorrelated function are significantly lower within the timing uncertainty window than the sidelobe levels of a non-optimized autocorrelation function of a signal, the likelihood of finding a peak for the wrong timing signal is greatly reduced.

Abstract: The present invention is directed to a power transformer and VSD mounted on the chiller equipment. The transformer is preferably a liquid-filled transformer rated for medium/high voltage input, and at least two output low voltages, one voltage for the VSD and other power equipment, and another voltage for the control panel and control equipment. The placement of the power transformer on the chiller eliminates the need to allocate additional floor space for an auxiliary transformer or medium/high voltage VSD. The transformer also includes cooling means in the form of a heat exchanger in which the liquid is cooled by circulating condenser water, chilled water or refrigerant from the chiller system. The cooling means may also be connected to cooling coils connected to the VSD.

Abstract: A method and system is provided for gathering and packetizing data from networked building automation equipment, and for transmitting data packets as instant messages to remotely located users. An instant messaging (IM) server-based system is provided to facilitate communication between networked building equipment and a remotely located service contractor. When a registered router is operated, the router establishes a continuous pass-through communication link with the IM server and with building equipment connected to the router. The router automatically polls connected building equipment for alarms, faults and system failures, and also receives, processes, and responds to user requests for specific data from particular items of building equipment. Data gathered by the router is packetized, and the packets are then encapsulated into an instant message that is transmitted to the IM server.
