Abstract
A container comprising a body having embedded therein a plurality of chipless radio frequency identification elements. The chipless radio frequency identification elements comprises a plurality of categories of resonant elements. The resonant elements can be utilized in a system having a binary code feature. The combination of different resonant elements can be read and translated to identify the features of a particular product. The container can be prepared by compounding moldable compositions with the resonant elements and molding the moldable compositions containing the resonant elements into the final product. The invention also provides a system and a method for reading the binary code provided by the chipless radio frequency identification elements.

A method for communicating radio frequency identification signals with a medical component, the method comprising:
- providing a pulsed signal from a radio frequency identification reader to a medical component that includes a radio frequency identification device with an antenna;
- tuning the antenna to receive electromagnetic waves from the pulsed signal that induce a current in the antenna, tuning the antenna including aligning a coil with the electromagnetic waves from the radio frequency identification reader to intercept a maximum electromagnetic signal from the electromagnetic waves for inducing the current in the antenna;
- receiving, at the radio frequency identification reader, one or more response signals including one or more modulated electromagnetic waves from the medical component;
- converting the received one or more responses including the modulated electromagnetic waves into digital data associated with the medical component;
- storing in a memory the digital data associated with the medical component;
- and
- providing input/output channels for controlling a device external to the radio frequency identification reader.
An apparatus for communicating radio frequency identification signals with a medical component, comprising:
- a radio frequency identification reader configured to provide a pulsed signal;
- a medical component including a radio frequency identification device with an antenna, the antenna tuned to receive electromagnetic waves from the pulsed signal of the radio frequency identification reader, the electromagnetic waves including a current in the antenna, the antenna including a coil aligned with the electromagnetic waves from the radio frequency identification reader to intercept a maximum electromagnetic signal from the electromagnetic waves for inducing the current in the antenna;
- wherein the radio frequency identification reader is further configured to receive one or more response signals including one or more modulated electromagnetic waves from the medical component, to convert the received one or more responses including the modulated electromagnetic waves into digital data associated with the medical component, to store in a memory of the reader the digital data associated with the medical component, and to provide input/output channels for controlling a device external to the radio frequency identification reader.
