摘要： Systems and methods for dynamically changing displayed content of a tag coupled to an item. The methods comprising: detecting when an individual is in proximity to the tag; triggering operations, by a computing device remote from the tag, to obtain customer related information associated with the individual, when a detection is made that the individual is in proximity to the tag; determining, by the computing device, a price discount for the item based on the customer related information which was previously obtained; and dynamically changing the displayed content of the tag to include the price discount while the individual is still in proximity to the tag.

摘要： Systems and methods for operating a security tag. The methods comprise: receiving a first wireless signal transmitted from a transmit circuit using a receive circuit of the security tag; inducing a voltage in the receive circuit of the security tag while the first wireless signal is being received; performing operations by the controller to selectively close a switch when the voltage is being induced in the receive circuit; and causing a release of a mechanical component of the security tag by allowing energy to flow from the receive circuit to the mechanical component when the switch is closed.

摘要： Systems and methods for operating an Electronic Smart Tag (“EST”). The methods involve: operating the EST in a first operational state in which first item related information is output from an electronic output device of the EST that is powered by an energy storage device storing energy harvested from an external energy source; detecting when a charge level of the energy storage device reaches or falls below a first threshold level; and transitioning an operational state of the EST from the first operational state to a second operation state in which a message is output from EST requesting that a mobile device be placed in proximity to the EST for purposes of obtaining at least a first portion of the first item related information, in response to the detection that the charge level of the energy storage device has reached or fallen below the first threshold level.

摘要： System for controlling access comprises a reader unit (108) which is disposed at a portal (102) to a controlled access area (118) and a wearable access device (WAD) (114) which is worn by a user (116). The reader and the WAD implement a bidirectional optical communication protocol (BOCP) to communicate digital data. The WAD receives an interrogation signal from the reader for initiating an access control interaction. At least one of the reader and the WAD uses a predetermined optical beam width (142, 308) and a boresight direction (140, 306) of an optical beam associated with the wireless optical communication link to facilitate a selective determination as to whether the WAD will respond to the interrogation signal with a reply signal to continue with the access control interaction.

摘要： Systems (100) and methods (400) for powering an electrical load (322) in an environment. The methods involve using a battery (310) to simultaneously supply electrical energy to control electronics (308, 316) and a Super Capacitor (“SC”) storage element (314) immediately after a system has been disposed in the environment and turned on. In effect, the control electronics are caused to perform intended functions thereof nearly instantaneously after turning on the system. The SC storage element is charged from a first charge state in which approximately zero volts exist across terminals thereof to a second charge state in which greater than zero volts exists across the terminals. The SC storage element is then used to supply electrical energy to the electrical load of the system so as to cause the electrical load to perform intended functions thereof.

摘要： A product information system including a server having an item database that stores at least one item identifier and corresponding item data for at least one item. Also, the item database is associated with a predetermined vendor. The server also includes a receiver that receives a message including tag data captured from a tag by a portable wireless device. The tag data includes an item identifier. Also, the server includes a processor that operates, in response to the received message, to select item data from the item database that corresponds to the received item identifier. The server also includes a transmitter that transmits the selected item data to the portable wireless device.

摘要： Systems and methods for controlling at least one security device based on the behavior of at least one tag. The methods comprise: generating sensor data relating to movement by at least one sensor disposed in a first tag; analyzing the sensor data to determine if an item to which the first tag is coupled is being handled in an unusual, abnormal or nervous manner; determining if an enterprise system has lost communicative contact with the first tag coupled to the item that is being handled in an unusual, abnormal or nervous manner; and causing an operational state of the security device to change in response to the loss of the communicative contact between the enterprise system and the first tag.
