  • Patent number: 10276014
    Abstract: Techniques are described for distributing, to a distributed network of central stations, alarm events detected in monitoring system data collected by sensors included in monitoring systems located at monitored properties. A system receives monitoring system data collected by sensors included in monitoring systems located at monitored properties, tracks alarm events detected within the monitoring system data, and generates, for central station servers in a distributed network of central stations, load profiles that reflect a volume of alarm events being handled at each of the central station servers at a particular period of time. The system determines capacities to handle additional alarm events for the central station servers, determines relative priorities for the central station remote servers based on the determined capacities, and directs subsequent alarm events to the central station servers based on the relative priorities.

  • Patent number: 8641413
    Abstract: A device for producing a stable and augmented flame includes a fluid-inducing assembly and a shield. The fluid-inducing assembly includes a flow-diverting mechanism defining a flow-intake end and a flow-accelerating end and includes a plurality of vanes extending from the flow-intake end to the flow-accelerating end. The plurality of vanes is circumferentially disposed and spaced from one another. Furthermore, two vanes include a space defined therebetween, and the space defines a passage which is spiral-shaped. The flow-diverting mechanism further includes a covering member with an enclosed circumferential edge circumferentially surrounded. Thus, each vane in the flow-accelerating end is encircled by the covering member, and each vane in the flow-intake end is exposed to outside and not covered by the covering member. In addition, the shield is hollow and is disposed above the fluid-inducing assembly.

  • Patent number: 5165883
    Abstract: A process and apparatus for monitoring and ensuring safe operation of unvented kerosene heaters in indoor spaces detects the hazard of incomplete combustion and the concomitant reduced O.sub.2 and increased CO.sub.2 levels in the indoor air. CO.sub.2 level in the indoor air is monitored quickly and accurately, - regardless of the burner's flame height. This is achieved by sensing O.sub.2 level in the burner exhaust which is used as a measure for monitoring the CO.sub.2 level in the indoor air and as a control signal. During burner operation outside a predetermined flame height range, the O.sub.2 detection is used both for restoring a normal heating condition and for monitoring operation at minimum flame height and to generate a warning signal and a delayed automatic shut-down of the burner.
