NON-CONTACT ELECTRONIC DOOR LOCKS HAVING SPECIALIZED RADIO FREQUENCY BEAM FORMATION
First Claim
1. An electronic door lock adapted to interact with an electronic key unit having a key antenna and a transmitter configured to transmit a radio frequency (“
- RF”
) signal over the key antenna, the RF signal containing an identification (“
ID”
) code identifying the electronic key unit, the electronic door lock comprising;
a first antenna adapted to form a first directional radiation beam to receive the RF signal from the key unit;
a second antenna adapted to form a second directional radiation beam to receive the RF signal from the key unit; and
a processing component adapted to use RF signals received by one or both of the first and second antenna to determine whether the presence of an acceptable ID code is detected on the key.

Abstract
An electronic door lock (“EDL”) is adapted to interact with an electronic key unit having a key antenna and a transmitter configured to transmit a radio frequency (“RF”) signal over the key antenna, the RF signal containing an identification (“ID”) code identifying the electronic key unit. The EDL can include a first antenna adapted to form a first directional radiation beam to receive the RF signal from the key unit, a second antenna adapted to form a second directional radiation beam to receive the RF signal from the key unit, and a processing component adapted to use RF signals received by one or both of the first and second antenna to determine whether the presence of an acceptable ID code is detected on the key. The EDL can determine the location of the key, and whether the key is inside or outside of the room.

20. An electronic door lock system, comprising:
-
a plurality of electronic door locks adapted to interact with an electronic key unit having a key antenna and a transmitter configured to transmit a radio frequency (“
RF”
) signal over the key antenna, the RF signal containing an identification (“
ID”
) code identifying the electronic key unit, wherein each of the plurality of electronic door locks includes a first antenna adapted to form a first directional radiation beam to receive the RF signal from the key unit, a second antenna adapted to form a second directional radiation beam to receive the RF signal from the key unit, a processing component adapted to use RF signals received by one or both of the first and second antenna to determine whether the presence of an acceptable ID code is detected on the key; anda server in communication with the plurality of electronic door locks, said server being adapted to update information on each of the plurality of electronic door locks regarding ID codes for new or reissued electronic key units.
