RFID pet door
First Claim
1. A radio frequency identification pet door, the pet door comprising:
- an RFID reader to read an RFID tag on a pet;
a lock, coupled to said RFID reader, to control access through said pet door in response to an RFID signal from said RFID tag;
wherein said RFID reader is able to read a pet identification code from both;
i) a sub-dermal RFID tag; and
ii) a collar-mounted RFID tag; and
wherein a given pet has a collar-mounted RFID tag and a sub-dermal RFID tag;
wherein said lock is controlled to selectively allow access of a pet with a said sub-dermal RFID tag, a pet with a collar-mounted RFID tag and said given pet with both said collar-mounted RFID tag and said sub-dermal RFID tag through said pet door responsive to a respective said pet-identification code read from the RFID tags; and
wherein said sub-dermal RFID tag operates at a first frequency said collar-mounted RFID tag operates at a second, different frequency;
wherein said first frequency is in the range of 125 KHz to 134 KHz;
wherein said RFID reader has an RF communications bandwidth spanning both first and second frequencies;
said RFID pet door further comprising;
a frame mounting a moveable flap, wherein opening of said moveable flap is controlled by said lock;
a tunnel attachment to said frame; and
an antenna of said RFID reader mounted on or adjacent said tunnel;
wherein said tunnel extends away from said moveable flap.

Abstract
Embodiments of the invention relate to the field of pet doors, particularly selective entry pet doors based on detection of RFID tags. An RFID pet door, the pet door comprising: an RFID reader to read an RFID tag on a pet; and a lock coupled to said RFID reader to control access through said pet door in response to an RFID signal from said tag; wherein said RFID reader has two modes, a first operational mode and a second, reduced power mode, and wherein said pet door further comprises: a pet proximity detector coupled to said RFID reader to identify when a pet is proximate said pet door and to control said RFID reader responsive to said identification such that when said pet is proximate said RFID is in said operational mode and such that said RFID reader is otherwise in said reduced power mode.

8. A method of controlling access of a pet through a pet door, the method comprising:
-
providing a radio frequency identification reader able to read an tag over a plurality of different frequencies; detecting a sub-dermal RFID tag in a first said pet at a first frequency using said RFID reader; controlling a lock of said pet door using said RFID reader to control access of said first pet through said pet door; detecting a collar-mounted RFID tag on a second said pet at a second frequency using said RFID reader; controlling said lock of said pet door using said RFID reader to control access of said second pet through said pet door; detecting both a collar-mounted RFID tag and a sub-dermal RFID tag on a third said pet at a second frequency using said RFID reader; and controlling said lock of said pet door using said RFID reader to control access of said third pet through said pet door. - View Dependent Claims (9, 10, 11)
