摘要： Binary messages received over a radio channel are subject to fading or noise degradation because of the radio channel. Accordingly, a predetermined binary preamble followed by a synchronizing word are transmitted ahead of the message. In order that the synchronization be correct, the end of the preamble should be determined as accurately as possible. This is achieved by fast and slow detectors which receive the preamble. The fast detector output is applied to a time delay. The slow detector and the time delay outputs are applied to an output circuit which produces an output signal in response to the slow detector and the time delay outputs both being present. The fast and slow detectors and the time delay are arranged so that the output signal is produced at the desired time after the preamble begins, thereby accurately indicating when the synchronizing word is to begin.

摘要： Predictive theft notifications are used to coordinate appropriate responses to persons who are likely to commit acts of theft. Image data is generated and processed in a computer processing device to recognize the presence of a facial image comprising a face of a person. An analysis is performed of data representative of the facial image to determine a biometric match relative to one or more biometric models of facial images stored in a database. Based on this analysis, at least one predictive notification is generated with regard to a future potential theft of merchandise from the secured facility. The predictive notification is generated based upon a determination of the biometric match.

摘要： Systems and methods for operating an Unmanned Mobile Machine (“UMM”). The methods comprise: detecting, by a Loss Prevention System (“LPS”), an unusual activity by at least one individual in a facility; communicating a signal from the loss prevention system to the UMM, in response to the detection of the unusual activity; transitioning an operational state of the UMM from a first state in which at least mitigation operations are disabled to a second state in which the mitigation operations are enabled, in response to the signal's reception at the UMM; and performing the mitigation operations by the UMM to visibly follow an individual associated with the unusual activity.

摘要： Systems and methods for making a marker. The methods comprise: disposing a resonator with a flat planar cross-sectional profile in a cavity formed in a first substrate partially defining a marker housing; sealing the cavity using a second substrate; placing a first bias element adjacent to the second substrate so that the resonator will be biased by the first bias element when the marker is in use to oscillate at a frequency of a received transmit burst; and using a physical structure in the cavity or a magnetic field passing through the cavity to reduce frictional forces between the resonator and at least the second substrate.

摘要： Systems and methods for making a marker. The methods comprise: obtaining a marker housing having first and second cavities formed therein; disposing a first resonator in the first cavity and a second resonator in a second cavity; and placing a bias element at a location on or in the marker so that the first and second resonators are (a) equally spaced apart from the same bias element and (b) biased by the same bias element when the marker is in use to oscillate at a frequency of a received transmit burst.

摘要： Systems (100) and methods (1100) for activating an Electronic Article Surveillance (“EAS”) element deactivator. The methods involve: obtaining customer-related data from a customer of a business organization who is attempting to deactivate an EAS element of at least one item; obtaining transaction data contained in a receipt issued upon completion of a checkout transaction for the customer; communicating the customer-related data, transaction data and a unique identifier for an EAS element deactivation system to a remote computing device; processing the customer-related data and transaction data to obtain confirmation that the customer has recently successfully completed the checkout transaction for the item and the EAS element of the item has not yet been deactivated; and activating the EAS element deactivator of the EAS element deactivation system subsequent to when the confirmation is obtained.

摘要： A method of making a magnetomechanical electronic article surveillance marker is provided that, in one embodiment, includes deposition or placing of at least one elongated bias magnet onto a substrate, depositing a cavity layer onto the substrate where the cavity layer defines an elongated cavity adjacent the bias magnet. Placing a magnetomechanical resonator into the cavity and sealing a cover onto the cavity layer wherein the resonator is captured in the cavity and free to mechanically vibrate substantially unencumbered. The substrate itself may be magnetic thereby eliminating a separate bias magnet. In an alternate embodiment, a cavity is molded in a plastic substrate sized to fit a resonator, and a cover is sealed to the substrate to capture a resonator in the cavity. At least one bias magnet is placed onto the cover adjacent the cavity and a second cover is sealed to the substrate, to the first cover, and to the bias fixing the bias in place adjacent the cavity.
