  • Multi-sensor detectors
    Patent number: 8249811
    Abstract: A multi-sensor fire detector incorporates at least one acoustic resonator and other type or types of fire sensor. Other types include smoke sensors, gas sensors or optically based fire sensors. Outputs from the acoustic resonator can be processed with or without outputs from the other type or types of fire sensors to establish the presence of an alarm condition. Multiple acoustic resonators can be incorporated into the same detector.
    Type: Grant

  • System and method of detecting human presence
    Patent number: 7985953
    Abstract: A detector of human emitted Blackbody radiation includes a plurality of series connected thermocouples. A lens can be associated with each of the thermocouples. Incoming radiation produces a different response in each of the thermocouples in accordance with a respective angle of arrival even from a motionless radiation source.

  • Smoke detectors
    Patent number: 7493816
    Abstract: An aspirated smoke detector includes a flow path and a generator of acoustic waves in the flow path. Airborne particulate matter in the flow path responds to the acoustic field by particle agglomeration; the resulting larger particles flow into a photoelectric-type smoke sensor. A sensed level of particles can be processed, or compared to one or more predetermined thresholds to establish presence of one or more predetermined conditions.

  • Camera vision fire detector and system
    Patent number: 7495573
    Abstract: Wide area camera vision systems can respond to variations in light beams projected into a region being monitored. The variations are indicative of the presence of smoke in the region. In addition to providing viewable images of the region being monitored, analysis software can be used to evaluate the extent of smoke in the region or regions being monitored.

  • System for monitoring activities and location
    Patent number: 7405653
    Abstract: A residential monitoring system incorporates both physiological sensors and activity sensors. Some of the sensors can be in wireless communication with control circuitry. One or more activity profiles can be established for a resident to expand upon and supplement information from the physiological sensors.

  • Detector with condenser
    Patent number: 7360397
    Abstract: An ambient condition detector has a housing that carries a sensor of an airborne constituent such as a gas, and a condenser for minimizing an inflow of moisture into the sensor. A filter can be used to reduce fluid flow velocity prior to passing through or by the condenser.

  • Chamber for gas detector
    Patent number: 7034304
    Abstract: A gas sensor, which could be a sensor of combustible gases, incorporates a diffusion chamber having symmetrical sensing and reference portions. A common source emits infrared-type radiant energy symmetrically into the two portions. Each portion incorporates a curved reflective surface which reflects incident infrared onto a respective sensor. Each sensor has a filter which passes a different selected band of energy. A fluid, such as gas being sensed, passes laterally through the chamber.
