Abstract: 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 are 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.

Abstract: Method, system and computer program for obtaining information about telecommunications devices that transmit signals seeking available Wi-Fi connectivity. One or more Wi-Fi beacons are configured to detect probing signals from any telecommunications device in its range, a processor at each Wi-Fi beacon extracts an identifier of each telecommunications device from detected probing signals and each Wi-Fi beacon is associated with the identifier of any telecommunications devices whose probing signals have been received by that Wi-Fi beacon to thereby determine the presence and optionally position of any telecommunications devices within the range of the Wi-Fi beacon. The telecommunications devices are not involved in the method other than providing in their usual manner of operation, probing signals containing identifiers.

Abstract: 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.

Abstract: 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.
