Abstract: The disclosed system, methods, and apparatus relates to a self-cleaning litter box. The self-cleaning litter box includes a movable rake. A mechanism controlling the rake can allow for control of the forward/reverse position, the vertical position, and the rotation of the rake using a different path of travel for the forward and reverse traversals of the rake across the litter box. The controlled positioning of the rake can reduce force on the rake and other mechanical components, and more evenly distribute litter. Further, some implementations may include a dumping mechanism that involve the rake flipping so that clumps of pet waste are forcibly removed from the rake by a mechanical impact. Further implementations allow for removal/replacement of the rake.

Abstract: A pet door includes a latch assembly for locking and unlocking a pet flap. The latch assembly has an electric motor, a motor drive shaft having a first end coupled to the electric motor and a second end oppositely disposed from the first end, a drive pin coupled to the second end of the motor drive shaft, and a drive wheel coupled to the drive pin. The drive wheel incrementally rotates with each full rotation of the drive pin. The drive wheel is coupled to a cam drive shaft. The latch assembly also has plurality of latches assemblies coupled to the cam drive shaft for selective engagement of the peripheral edge of the flap depending upon the rotational position of the cam drive shaft, the selective engagement between the latches and the peripheral edge of the flap determining the locking and unlocking of the flap relative to the frame.

Abstract: A pet door includes a motor for locking and unlocking a pet flap of a pet door. The pet flap is rotatably attached to an upper portion of the pet door. The flap has at least one peripheral edge and a movable seal coupled to the flap for reciprocal movement between a retracted position and an extended position. The seal has a second magnetic portion that is magnetically attracted to the first magnetic portion of the frame. The seal is biased to the retracted position when the door is open and the seal being magnetically biased to the extended position by the magnetic force between the first and second magnetic portions when the door is closed.

Abstract: A pet door is described herein comprising a motor for locking and unlocking a pet flap of a pet door, wherein the pet flap is rotatably attached to an upper portion of the pet door. The pet door includes a first motion detector for monitoring movement in a first detection region and a second motion detector for monitoring movement in a second detection region, wherein the pet flap of the pet door occupies a plane separating the first detection region from the second detection region when the pet flap is in a locked position. One or more applications running on at least one processor of the pet door are configured to receive a first motion signal from the first motion detector indicating movement of a pet in the first detection region, the receiving the first motion signal including activating an access sequence controlling ingress or egress of a pet.
