摘要:
A system for air purification based on in-situ photocatalytic oxidation and ozonation includes a single multi-functional Ti02-based coating having photocatalytic activity for oxidation in the presence of a sufficient ozone supply and UV irradiation to synergistically oxidize gaseous pollutants at ambient conditions. Also disclosed is a method for removing gaseous pollutants using ozone and UV irradiation to simultaneously activate the photocatalytic oxidation in the presence of the Ti02-based coating to remove up to about 84% of the gaseous pollutants within 5 minutes.

A security tag and system for securing objects, the system and security tag includes an acousto magnetic (“AM”) electronic article surveillance (“EAS”) component that has a housing with a defined surface area. The housing of the EAS component includes a perimeter boundary that defines an EAS component plane. The system and security tag further include a radio frequency identification (“RFID”) component that includes an integrated circuit and a dipole antenna defining an RFID component plane that is substantially coplanar with the EAS component plane. The integrated circuit and the dipole antenna are positioned externally along the perimeter boundary of the EAS component.
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:
A system and method selectively reads radio frequency identification (“RFID”) tags within an RFID interrogation zone. A portion of the RFID tags have a first operating range and a portion of the RFID tags have a second operating range that is different from the first operating range. Each RFID tag is programmed with an identifier associated with the operating range of the RFID tag. A first interrogation signal is transmitted which has sufficient power to activate RFID tags that are located within the RFID interrogation zone and have the first operating range. A response signal is received from each RFID tag capable of receiving the first interrogation signal. Each response signal indicates the identifier of the associated RFID tag. Each RFID tag that has an identifier associated with the first operating range is selected.
摘要:
A method and system for security tag attachment using a reversible adhesive in which a security tag has an outer surface and an inner volume. The tag includes at least one of an Electronic Article Surveillance (EAS) element and a Radio Frequency Identification (RFID) element disposed within the inner volume. The system also includes a reversible adhesive disposed on at least a portion of the outer surface.

Security tag includes a housing and a movable locking element. A latch within the housing is resiliently biased toward the movable locking element and movable responsive to a magnetic field between a locked position and an unlocked position. A guide structure is arranged to constrain movement of the latch. The latch and the guide structure are cooperatively arranged to ensure an engagement that will disrupt a motion trajectory of the latch occurring when the housing is subjected to a physical impact. Consequently, the latch is selectively inhibited from moving fully from the locked position to the unlocked position when the housing is subjected to the physical impact.
摘要:
A security system tag. The security system tag includes a housing. The security system tag further includes an electronic article surveillance, EAS, element in which the EAS element is arranged to emit a detectable signal when introduced to an interrogation signal. The security system tag further includes a metal element in which the metal element is adapted to be heated. The security system tag further includes a first reversible adhesive proximate the metal element in which at least a portion of the first reversible adhesive de-bonds when thermally affected by the metal element when the metal element is heated.
