    摘要: A system for multimodal biometric identification has a first imaging system that detects one or more subjects in a first field of view, including a targeted subject having a first biometric characteristic and a second biometric characteristic; a second imaging system that captures a first image of the first biometric characteristic according to first photons, where the first biometric characteristic is positioned in a second field of view smaller than the first field of view, and the first image includes first data for biometric identification; a third imaging system that captures a second image of the second biometric characteristic according to second photons, where the second biometric characteristic is positioned in a third field of view which is smaller than the first and second fields of view, and the second image includes second data for biometric identification. At least one active illumination source emits the second photons.

    摘要: An automated exterior fire protection system deploys a fire resistant blanket that is preferably stored under the roof of the structure. Threatening fires are detected by a sensor to provide a signal that initiates automatic deployment of the blanket. Air bleed portions may be provided in the blanket to allow air trapped between the blanket and the structure to quickly dissipate. Moreover, elastic straps may be provided in the blanket to secure the blanket in place.
