    Abstract: A wireless device comprises a transceiver and a scheduling system. The transceiver transmits and receives messages to and from an access point, and has a sleep mode from which it occasionally wakes at wakeup times to listen for beacons from the access point. The scheduling system schedules wakeup times according to historical beacon synchronization data.

    Abstract: A system and method for performing automated defect detection by utilizing data from prior inspections is disclosed. The system and method may include providing a image capture device for capturing and transmitting at least one current image of an object and providing a database for storing at least one prior image from prior inspections. The system and method may further include registering the at least one current image with the at least one prior image, comparing the registered at least one current image with the at least one prior image to determine a transformation therebetween and updating the database with the at least one current image.

    Abstract: A method for detecting flame and smoke using spatial analysis of video input (40) provided by a video detector. The video input (40) consists of a number of individual frames, wherein analysis is performed on each individual frame to detect and outline regions that may contain smoke or flame (42). Based on the defined outline or boundary of each detected region, spatial features associated with the region are extracted (52), such as perimeter/area and surface area/volume. The extracted spatial features are related to one another (54) to determine the likelihood that the region contains smoke or flame. Extracted spatial features may be related to one another using a power law relationship that provides an indication of the turbulence associated with a bounded region, wherein turbulence is a characteristic of both flame and smoke.

    Abstract: A method for recognizing fire using block-wise processing of video input provided by a video detector. Video input is divided into a plurality of frames (42), and each frame is divided into a plurality of blocks (44). Video metrics are calculated with respect to each of the plurality of blocks (46), and blocks containing the presence of fire are identified based on the calculated video metrics (74). The detection of a fire is then communicated to an alarm system.
