Methods and apparatus for pet doors
A pet access control system according to various aspects of the present technology may comprise a door unit interoperable with a security panel holder. The door unit covers a passage through a structure, such as through the wall or door of a building. The door unit may include a connector that may be mounted on a legacy security panel holder or a dedicated mounting system for the door unit. The door unit may operate in conjunction with a pet identification system to automatically identify and grant access only to authorized pets. In various embodiments, the door unit may be controlled remotely, such as via a web browser on a remote computer or an app running on a smartphone.
1. A door unit configured to connect to a pet door security panel holder having a groove, comprising:
a frame having a hole defined therethrough;
a door disposed over the hole and mounted on the frame; and
a security panel interface on the frame comprising a lip adapted to slide into and engage the groove and hang the frame on the security panel holder, wherein the security panel interface comprises a nondedicated connector adapted to hang on multiple legacy security panel holders of different origins.
2. A door unit according to claim 1 , wherein the door opens only away from the security panel holder.
3. A door unit according to claim 1 , wherein the nondedicated connector comprises a selectable modular connector, wherein the selectable modular connector comprises the lip adapted to slide into and engage the groove and hang the frame on the security panel holder.
4. A door unit according to claim 1 , further comprising a tag sensor disposed on a central part of the door, wherein the tag sensor comprises a directional wireless Bluetooth sensor comprising:
an interior sensor disposed on a first side of the door;
an exterior sensor disposed on a second side of the door; and
a shield housing, wherein the shield housing shields the interior sensor from signals from a first direction and shields the exterior sensor from signals from a second direction.
5. A door unit according to claim 1 , further comprising:
a motor, wherein the motor drives movement of the door; and
a control system responsive to external signals, wherein:
the motor is responsive to the control system; and
the control system causes the motor to open the door in response to the external signals.
6. A door unit according to claim 5 , wherein the motor is disposed inside the door.
7. A door unit according to claim 1 , wherein the frame obscures the security panel holder when the frame is hung on the security panel holder.
8. A door unit according to claim 1 , wherein the frame and the door are oriented substantially parallel to the security panel interface.
9. A door unit configured to connect to a pet door security panel holder having a groove and respond to a signal from an authorized tag associated with a pet, comprising:
a frame having a hole defined therethrough;
a door disposed over the hole and mounted on the frame;
a motor, wherein the motor drives movement of the door;
a security panel interface on the frame comprising a lip, wherein the lip slides into and engages the groove and hangs the frame on the security panel holder, wherein the security panel interface comprises a nondedicated connector adapted to hang on multiple legacy security panel holders of different origins; and
a control system responsive to signals from the tag, wherein the motor is responsive to signals from the control system.
10. A door unit according to claim 9 , wherein the door opens only away from the security panel holder.
11. A door unit according to claim 9 , wherein the security panel interface comprises a selectable modular connector, wherein the selectable modular connector comprises the lip adapted to slide into and engage the groove and hang the frame on the security panel holder.
12. A door unit according to claim 9 , further comprising a tag sensor disposed on the door, wherein:
the tag sensor comprises a directional wireless Bluetooth sensor comprising:
an interior sensor disposed on a first side of the door;
an exterior sensor disposed on a second side of the door; and
a shield housing, wherein the shield housing shields the interior sensor from signals from a first direction and shields the exterior sensor from signals from a second direction; and
the control system causes the motor to open the door when the tag sensor receives the signal from the authorized tag.
13. A door unit according to claim 12 , wherein the tag sensor is disposed on a central part of the door.
14. A door unit according to claim 9 , wherein the frame and the door are oriented substantially parallel to the security panel interface.
15. A door unit according to claim 9 , wherein the frame obscures the security panel holder when the frame is hung on the security panel holder.
16. A method of operating a door unit configured to connect to a pet door security panel holder having a groove and surrounding an opening, comprising:
positioning a frame having a hole defined therethrough adjacent the opening, wherein the hole is aligned with the opening; and
hanging the frame on the security panel holder via a security panel interface comprising a lip on the frame, comprising sliding the lip into the groove and engaging the groove to the lip, wherein the security panel interface comprises a nondedicated connector adapted to hang on multiple legacy security panel holders of different origins.
17. A method of operating a door unit according to claim 16 , wherein hanging the frame on the security panel holder comprises orienting the frame substantially parallel to the security panel holder.
18. A method of operating a door unit according to claim 17 , further comprising:
determining whether a sensed signal corresponds to an authorized tag; and
determining whether the pet is on a first side of a door or a second side of the door, comprising:
sensing the signal from the direction of the first side of the door;
sensing the signal from the direction of the second side of the door; and
comparing the signals as sensed from the first and second sides of the door.
19. A method of operating a door unit according to claim 16 , wherein the security panel interface comprises a selected modular connector, further comprising:
selecting the selected modular connector from a plurality of modular connectors, wherein the selected modular connector is configured to engage the security panel holder and comprises the lip; and
mounting the selected modular connector on the frame.
20. A method of operating a door unit according to claim 16 , wherein hanging the frame on the security panel holder comprises obscuring the security panel holder with the frame.
