Abstract: A spectrum profiling device may be configured to generate an energy profile of a monitoring environment in which a tag adapted to be disposed on a product in the monitoring environment is detectable via a monitoring network. The device may include processing circuitry configured to receive information indicative of energy data obtained by a measurement device disposed in the monitoring environment, associate the energy data with corresponding location information describing a plurality of locations at which the energy data was obtained within the monitoring environment, and generate the energy profile providing an indication of baseline energy levels of a selected energy spectrum for the monitoring environment based on the energy data and the location information.

Abstract: A tag controller may be configured to interface with one or more security tags and at least one of the tags may be adapted to be disposed on a product in a monitoring environment. The tag controller may include processing circuitry configured to receive location information indicative of tag location responsive to initial movement of a tag, and compare the location information to alerting criteria. The alerting criteria may include at least a position component and a temporal component. The processing circuitry may be further configured to initiate an alerting function responsive to the alerting criteria being met.

Abstract: A tag controller is configured to interface with a tag on a product in a monitoring environment that includes first and second monitoring zones. The first monitoring zone includes first locator devices, and the second monitoring zone includes second locator devices. The tag controller includes processing circuitry configured to facilitate operation of the tag in a first mode to employ wireless communication with the first locator devices or the second locator devices to generate position information usable for locating the tag in the monitoring environment. The first mode defines communication parameters associated with the wireless communication. The processing circuitry may also be configured to determine whether mode switch criteria are met, and direct the tag to switch to operation in a second mode to employ different communication parameters relative to wireless communication with the first locator devices or the second locator devices responsive to the mode switch criteria being met.

Abstract: A security system controller may include processing circuitry. The processing circuitry may be configured to receive information indicative of motion of a security tag disposed on a product in a monitoring environment, track motion of the security tag responsive to information received via wireless communication between the security tag and a plurality of locator devices of a first locating system, and determine whether a potential foil bag condition exists relative to the security tag based on a loss of communication with the security tag while tracking motion of the security tag.

Abstract: A tag controller is configured to interface with a security tag adapted to be disposed on a corresponding product in a monitoring environment. The tag controller includes processing circuitry configured to perform a tag position estimation by receiving information indicative of signal strength measured at the security tag relative to each of a plurality of locating beacons disposed in the monitoring environment, defining an order of a selected number of the locating beacons based on signal strength, determining a first midpoint between two of the selected number of the locating beacons having the lowest signal strengths, determining at least a second midpoint between the first midpoint and a locating beacon having a next lowest signal strength, and determining a location of the security tag at least in part based on the second midpoint.
