Abstract: The invention relates to a system and method for monitoring the status at a remote site from a control center. In one embodiment, the present system uses a client/server approach to security by having a client at a remote site monitor video, audio, and other sensor information and forward it to a server operated at a command center. By monitoring for various sorts of activity, the system can automatically alert an operator as to developing conditions at the remote site, contact local personnel, and, if so configured, alert law enforcement authorities or emergency personnel. When an alarm condition arises, the server will automatically provide the operator in the control center with live or still video feed from the remote site in a “pop-up” window with a color-coded outline to indicate the status of the remote site. A topographical map of the site may also be displayed, to enable local authorities to track an intruder or quickly locate the source of the alarm.

Abstract: A heat exchange fluid supply system for supplying a heat exchange fluid to an intravascular heat exchange catheter includes a disposable cassette having a bulkhead and an external heat exchanger, and which is configured to operate in combination with a reusable master control unit. The bulkhead includes a reservoir section and a pump section. The reservoir section is provided with a means to monitor the amount of heat exchange fluid that is in the system. The bulkhead provides the mechanism for priming the system with heat exchange fluid from an external source and for circulating fluid to the catheter in a closed circuit. The pump section is configured to allow for pumping of heat exchange fluid at a constant pressure.

Abstract: A roof membrane welding apparatus capable of applying a weld to a first membrane and an overlapping second membrane. The apparatus includes a movably supported chassis, a welder attached to the chassis for heating the top membrane to at least the vicant softening point to weld the overlapping second membrane and the first membrane, and at least one weld wheel rotatably attached to the chassis and located rearward of the nozzle relative to the direction of movement of the apparatus, the weld wheel including a marker having an indicia thereon that is transferred to a top surface of the second membrane only where the first membrane and the second membrane have undergone a phase change during heating.
