Abstract: An apparatus is provided including processing circuitry configured to determine a gravity vector of a device, detect a motion of the device, calculate a force vector of the motion, compare the force vector to the gravity vector to determine a vector difference, and determine if the vector difference satisfies a predetermined difference threshold.

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 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.

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: In accordance with at least one embodiment, a portable data terminal generally comprising a battery: a central controller, a GPS system, and an auxiliary processor. The central controller that has a sleep state wherein at least some of the functionality of the central controller is limited to conserve battery power. The auxiliary processor may be selected based, at least in part, on power draw. In particular, it is desirable for the auxiliary processor to use less power than the central controller when the central controller is fully activated. The auxiliary processor monitors the output of the GPS system and wakes the central controller from a sleep state based on the output of the GPS system.

Abstract: An improved method and device for capturing image data benefits from having a single central processor execute the operating system, and the image capture, decode and processing programs. A method for capturing of image data comprises transmitting image data from an imager, assembling the image data, assigning a memory address to the assembled image data and transferring the assembled image data into system memory. This method is capable of central processing whereby the capturing of image data is executed via the main processor without having to invoke a dedicated processor or incorporate external components, such as additional PCBs, external digital signal processing or external data storage. Additionally, an imaging device comprises an image builder module that receives image data from the imager bus and assembles the data, and a transfer controller that initiates the image builder module and controls the transfer of image data into and out of memory.
