    摘要: Monitoring technique includes identifying objects in images and associating color characteristics with each identified object. When the color characteristics of an object in one image is above a color resemblance threshold to the color characteristics of an object in another image, the object in both images is considered the same. Otherwise, the respective object in both images are considered to be different. Data about time that each image including an identified object was obtained and location of each object when each image including an identified object was obtained is derived. An information conveyance system is activated to convey the time and location-related data about identified objects relative to defined areas of the site or movement of the identified objects or people into, between or out of the defined areas of the site or a communication resulting from such data satisfying one or more conditions.

    摘要: A method and apparatus for determining a location of a wireless device using radio waves and pressure measurements is disclosed. In one embodiment, a plurality of Radio Signal Strength (RSS) measurements are used to trilaterate an approximate location of the wireless device. The wireless device also takes pressure measurements that are compared with a second pressure measurement made by at least one other pressure sensor at a known elevation and in a local area near the wireless device. This comparison is used to generate an accurate estimate of the elevation of the wireless device. The accurate estimate of elevation may be combined with the RSS measurements to yield an accurate estimate of the location of the wireless device.

    摘要: Systems, methods, and devices are described for determining a physical location of a wireless device. A receiver may be configured to receive associations between anchor locations and sensor nodes, wherein each sensor node uses near field communications to identify an anchor location. The receiver may also receive signal strength measurements from the wireless device measuring the signal strength of wireless sensor nodes. Arrangements may also be configured to determine physical locations of the sensor nodes based on physical locations of anchor locations and utilize received signal strength measurements with the determined physical locations of the sensor nodes to determine the physical location of the wireless device.
