    摘要： According to another embodiment, a method of detecting the occurrence of a condition using a detection system located within a predetermined area includes transmitting light from at least one node of a plurality of nodes into an ambient atmosphere adjacent the at least one node, receiving scattered light from the ambient atmosphere at the at least one node, communicating the received scattered light to a control system operably coupled to the at least one node, analyzing the scattered light at the control system to determine a condition of the ambient atmosphere adjacent each at least one node, and adjusting a sensitivity of the at least one node of the plurality of nodes.

    摘要： An auto-commissioning system provides automatic parameter selection for an intelligent video system based on target video provided by the intelligent video system. The auto-commissioning system extracts visual feature descriptors from the target video and provides the one or more visual feature descriptors associated with the received target video to an parameter database that is comprised of a plurality of entries, each entry including a set of one or more stored visual feature descriptors and associated parameters tailored for the set of stored visual feature descriptors. A search of the parameter database locates one or more best matches between the extracted visual feature descriptors and the stored visual feature descriptors. The parameters associated with the best matches are returned as part of the search and used to commission the intelligent video system.

    摘要： A multi-point detection system includes one or more light sources, one or more light sensors, and a controller. The light sources are configured to emit an array of collimated light beams, and the light sensors define an array of lines of view. Each of the lines of view intersect different ones of the collimated light beams at respective detection nodes. The light sensors are operable to emit sensor signals responsive to received scattered light from interaction of the collimated light beams with an analyte at the detection nodes. The controller is connected to receive the sensor signals and configured to determine from the scattered light whether the analyte contains a contaminant.

    摘要： A radar presence detection system is configured to detect oscillations within a building. The radar presence detection system includes an accelerometer, a radar, and a processing unit. The accelerometer is attached to the building and configured to detect structural vibration waves. The radar is configured to transmit a monitoring wave and receive a reflected wave. The processing unit includes a filter, an adaptive filter, and a detector. The filter is configured to receive a first signal indicative of the reflected wave and output a filtered reflected wave signal spanning a frequency range indicative of an oscillation within the building. The adaptive filter is configured to receive a second signal indicative of the structural vibration wave signal and output a focused vibration signal spanning a frequency range for the cancellation of vibration noise.
