Abstract: A method for encrypting and decrypting user data stored on identification tags, such as RFID tags, of the type having a tag identification code unique to each tag. An encryption/decryption key unique to each tag is based in part or in whole on the tag identification code of each tag, and the unique key is used to encrypt data for storage on the corresponding tag and to decrypt encrypted user data stored on the tag.

Abstract: A proximity reader for a radio frequency identification (RFID) system is programmed for determining and storing optimum antenna impedance values to achieve peak antenna resonance at each of multiple operating frequencies. Antenna resonance is peaked at power up and periodically during operation to compensate for environmental detuning influences. The reader scans the multiple frequencies to more effectively search for off-frequency identification tags.

Abstract: A motion transmitting remote control assembly (10) includes a core terminal (20) composed of a slider (26) and a sleeve (46). Flexible cantilever fingers (48) extend from the sleeve (46) and are inserted into an aperture (22) in the top of an accelerator pedal (16). A compression spring (64) is disposed between the sleeve (46) and the slider (26) for providing over travel protection. Splines (42) are positioned along the slider (26) to support the sleeve (46) as it slides thereover during operation. The improvement of this invention resides in distal tips (50) of the fingers (48) which angle into a protective position seated behind the end stop flange (34) of the slider (26). This arrangement allows the end stop flange (34) to center the terminal (20) as it is pushed through the aperture (22) in the accelerator pedal (16), instead of using the fingers (48) to center the terminal (20), thereby reducing the potential for misalignment or incomplete connection.
