Abstract
Systems and methods are disclosed herein for radio frequency identification (RFID) applications. For example, in accordance with an embodiment of the present invention, an RFID label is attached to an item (e.g., a metal object or a metal surface of the item) via an absorber to reduce electromagnetic interference.
Claims20
A radio frequency identification label comprising:
- a radio frequency identification device adapted to transfer information to a radio frequency identification reader, wherein the radio frequency identification device operates within a frequency range of approximately 12 to 15 MHz;
- and
- an FGM 40 absorber, coupled to the radio frequency identification device, adapted to reduce electromagnetic interference for the radio frequency identification device.
A radio frequency identification system comprising:
- a radio frequency identification label adapted to operate within a frequency range of approximately 12 to 15 MHz;
- and
- an FGM 40 absorber, coupled to the radio frequency identification label, adapted to reduce electromagnetic interference for the radio frequency identification label.
A method of reducing electromagnetic interference for a radio frequency identification system for a vehicle maintenance system, the method comprising:
- providing a radio frequency identification label adapted to operate within a frequency range of approximately 12 to 15 MHz;
- providing an FGM 40 absorber;
- and
- attaching the radio frequency identification label to an item comprising a replaceable part of the vehicle, wherein the absorber is disposed at least partially between the radio frequency identification label and the item.
