Abstract:
A spacing device and related method for improving readability of a container of RFID tagged items that are in relatively close proximity to each other is disclosed. The spacing device is preferably a low dielectric constant spacing device, wherein the nature of the device can be varied to create different effects on the readability of the RFID tagged items by preventing them from occupying areas with a large amount of material between the RFID tagged items and the RF reader. The spacing device is added into the container as the RFID tagged items are loaded into the container, and is preferably positioned in the center of the container. The spacing device can have a number of different dielectric, conductive and physical structures, and may be designed to be disposable, recyclable or re-used as needed.
Abstract:
An anti-tamper device combining a RFI D component and an article surveillance or security component with a visual indicator. The article surveillance or security component is operatively coupled to a display so that an interruption of the RFI D component is visibly indicated by the display. The visual indicator moves between a first state indicating a lack of tampering, and a second state indicating tampering without the need for a battery or external power source.
Abstract:
A system (100) and method for determining and communicating the status of a sealable container (102). The system comprises a seal status detection component (132) that is positioned adjacent to or on a lid (112) comprising a deflectable component. The lid engages the sealable container to form a seal (115). The seal status detection component moves between a first state of operation (130) where there is a gap between the seal status detection component and the deflectable component of the lid, and a second state of operation (140) where the seal status detection component is adjacent to or in contact with the deflectable component of the lid. The seal status detection component has a first frequency response to interrogation by a reader when the seal is intact, and a second frequency response when the seal is broken.
Abstract:
An RFID device includes an antenna defining a gap, with an RFID chip electrically coupled to the antenna across the gap. The RFID chip may be incorporated into an RFID strap, in which a pair of connection pads is connected to the RFID chip, with the connection pads connected to the antenna on opposite sides of the gap. Alternatively, the antenna may be connected to bond pads of the RFID chip. At least a portion of the antenna has a cross section with an at least partially curved perimeter. The cross section of the antenna may be differently shaped at different locations, such as having a flattened oval shape at one location and a substantially circular shape at another location. A portion of the cross section of the antenna may have a non-curved, relatively sharp edge, which may break through an outer oxide layer of a connection pad.
Abstract:
Medication containers are provided with a body having a wireless communication device secured to a lower surface of the body. The wireless communication device includes an RFID chip and a slotloop hybrid antenna electrically coupled to the RFID chip. The antenna includes a conductor sheet defining a slot and an aperture. The body defines a downwardly extending cell that is configured to receive a medication, with the aperture of the conductor sheet receiving at least a portion of the cell. The conductor sheet may include a plurality of apertures and the body may define a plurality of cells, with each aperture receiving a different one of the cells. A cover may be secured to an upper surface of the body to enclose the medication within the cell. If the medication container includes a plurality of cells and a frangible cover, it may be configured as a blister pack.
Abstract:
A packaging system that is manufactured entirely out of recyclable materials and that allows consumers to view the items, such as food items, within the package container is disclosed. Specifically, the packaging system comprises a package container manufactured entirely out of recyclable materials, and a code identifier component positioned thereon which is linked to an image or other information of the product contained within the package container. The code identifier component is typically a 2D bar code or an RFID tag. Further, the image linked to the code identifier component can be generic, or the actual individual image of the product in the container, and the image can be associated with the product during its manufacture, or when it is packaged. The image can be viewed with a tablet, mobile phone, virtual reality headset, a provided terminal, or other suitable device.
Abstract:
An RFID antenna structure is disclosed that is formed from a portion of a conductive material from a container seal. Generally, minimal material is removed from the container seal to form the antenna which thus retains most of the barrier properties of the conductive material. Further, an RFID tag device is coupled to either an outside or an inside of the barrier layer, and is attached after the container has been sealed to prevent the RFID tag device from being damaged during the sealing process.
Abstract:
An RFID device is provided with a substrate and a plurality of RFID components associated to the substrate. The substrate is initially provided in a substantially planar configuration, with the RFID components being associated to the substantially planar substrate. After the RFID components have been associated to the substrate, the substrate is folded at at least one fold line to give the substrate and resulting RFID device a non-planar structure. All or portions of at least two of the RFID components are associated to portions of the substrate that are present in different planes, which may include portions of the substrate that are oriented in generally parallel planes or at an angle to each other. By such a non-planar, three-dimensional configuration, an RFID device may be provided with enhanced functionality, including increased bandwidth, ability to receive and radiate signals in a plurality of distinct frequency bands, and directivity.
Abstract:
RFID tags are provided with a substrate including opposing first and second surfaces each having first and second portions defined by a fold line therebetween. A conductive trace defines a first coil associated with the first portion of the first surface and a second coil associated with the second portion of the first surface. The first coil has a first number of turns, while the second coil has a second number of turns. An RFID chip is electrically coupled to the conductive trace. The substrate is folded at the fold line so as to bring the first and second portions of the first surface into facing relationship, with at least a portion of the first coil overlapping at least a portion of the second coil. The overlapping coils define an antenna having a number of turns equal to the sum of the number of turns of the two coils.
Abstract:
A transponder includes a RFID tag and a Bluetooth low energy (Bluetooth LE) beacon communicatively connected using an inter-integrated circuit link. The Bluetooth LE beacon sends data such as battery status, temperature, or sensor data to the RFID tag which is retrieved by an RFID reader system. The RFID reader system sends updated messages, message repetition rate, and power data to the RFID tag to change the operating mode of the Bluetooth LE beacon. The RFID reader system selects the RFID tag which asserts a wakeup signal, or provides power to the Bluetooth LE beacon to start sending beacon messages. The RFID tag operates in a power-assist mode when receiving power from the Bluetooth LE beacon. The Bluetooth LE beacon increases the transmission power level when the RFID tag provides power to the Bluetooth LE beacon. The transponder can include a dual band UHF and ISM antenna.
