Pet door and method of operation
A pet door system including a door, a detection device, a receiver, a motor and a controller. The detection device detects the proximate presence of a pet to the door. The receiver receives an identification signal that establishes an identity of the pet. The motor is operatively connected to the door. The controller is communicatively coupled to the detection device, to the receiver and to the motor. The controller issues a signal to the motor to open the door based upon the identity of the pet.
1 . A pet door system, comprising:
a door;
a detection device that detects a proximate presence of a pet to said door;
a receiver to receive an identification signal that establishes an identity of the pet;
a motor operatively connected to said door; and
a controller communicatively coupled to said detection device, to said receiver and to said motor, said controller issuing a signal to said motor to open said door based on said identity.
2 . The pet door system of claim 1 , wherein said door is retractable.
3 . The pet door system of claim 2 , wherein said door includes a plurality of slats each pivotally interconnected with an adjacent one of said plurality of slats.
4 . The pet door system of claim 1 , further comprising:
a responding device one of located on the pet and subcutaneously located in the pet; and
a transmitter communicatively coupled to said controller, said transmitter sending a signal to said responding device.
5 . The pet door system of claim 4 , wherein said responding device is a radio frequency receiver and transmitter.
6 . The pet door system of claim 4 , wherein said responding device is an RFID device.
7 . The pet door system of claim 4 , wherein said responding device is located subcutaneously in the pet.
8 . The pet door system of claim 1 , further comprising a transition detection device communicatively coupled to said controller, said door revealing a passageway when said door is opened, said transition detection device detecting whether the pet is in said passageway and conveying information to said controller as to whether the pet is one of in and not in said passageway.
9 . The pet door system of claim 1 , wherein said detection device includes at least one of an RFID apparatus and a PIR apparatus.
10 . A door assembly, comprising:
an entryway door; and
a pet door installed in a lower portion of said entryway door, said pet door including:
a segmented door;
a detection device that detects a proximate presence of a pet to said segmented door;
a receiver to receive an identification signal that establishes an identity of the pet;
a motor operatively connected to said segmented door; and
a controller communicatively coupled to said detection device, to said receiver and to said motor, said controller issuing a signal to said motor to open said door based on said identity.
11 . The door assembly of claim 10 , wherein said segmented door is retractable.
12 . The door assembly of claim 11 , wherein said segmented door includes a plurality of slats each pivotally interconnected with an adjacent one of said plurality of slats.
13 . The door assembly of claim 10 , further comprising:
a responding device one of located on the pet and subcutaneously located in the pet; and
a transmitter communicatively coupled to said controller, said transmitter sending a signal to said responding device.
14 . The door assembly of claim 13 , wherein said responding device is a radio frequency receiver and transmitter.
15 . The door assembly of claim 13 , wherein said responding device is an RFID device.
16 . The door assembly of claim 13 , wherein said responding device is located subcutaneously in the pet.
17 . A method of operating a pet door, comprising the steps of:
detecting the presence of a pet;
obtaining an identity signal from a responding device that is one of attached to the pet and implanted in the pet; and
opening the pet door based on a match of said identity signal with a corresponding entry in a list of authorized identity signals.
18 . The method of claim 17 , further comprising the step of closing the pet door once the pet has transited the pet door.
19 . The method of claim 17 , further comprising the step of closing the pet door if the pet does not enter the pet door within a predetermined time.
20 . The method of claim 17 , further comprising the step of detecting a presence of the pet in a passageway of the pet door.
21 . The method of claim 17 , further comprising the step of indicating an acceptance of a new identity signal from another responding device associated with another pet.
22 . The method of claim 17 , wherein said responding device is an RFID device.
23 . The method of claim 17 , wherein said detecting step and said obtaining step each use at least a part of a dual detection device including a first detection device and a second detection device, said first detection device carrying out said detecting step, said second detection device carrying out said obtaining step.
24 . The method of claim 23 , wherein said first detection device is a passive detector, said second detection device being an active detector.
25 . The method of claim 17 , further comprising the step of enforcing an entry/exit pattern for the pet that determines whether or not the pet door will operate for the pet based on a set of predetermined criteria.
26 . The method of claim 25 , wherein said predetermined criteria include at least one of a time of day and a number of operations of the pet door for the pet in a predetermined time period.
27 . The method of claim 25 , wherein another pet has an other set of predetermined criteria.
28 . The method of claim 17 , further comprising the step of inhibiting opening of the pet door if a battery sensor indicates that a battery has insufficient energy to open and close the pet door.
29 . The method of claim 17 , further comprising the step of learning an additional identity signal from a transponder device and adding said additional identity signal to said list of authorized identity signals.
