TL;DR: In this article, an ultrasonic transceiver device and remote output devices controlled by the transceiver for use by domestic pets are presented, which utilizes a fixed interval edge detect modulation system to lock out stray environmental noise thereby, avoiding false triggering and greatly increasing the working range.
Abstract: An ultrasonic transceiver device and remote output devices controlled by the transceiver for use by domestic pets. The transceiver utilizes a fixed interval edge detect modulation system to lock out stray environmental noise thereby, avoiding false triggering and greatly increasing the working range. Output devices include: a wireless pet containment system in which ultrasonic transmitters are mounted on a series of posts defining the perimeter of the containment area and a receiver device adapted to be worn by a domestic animal. Upon receiving the transmitted ultrasound the receiver device sounds a warning tone followed by an electric shock to train the animal to stay within the perimeter; a sonic alarm system to deter a domestic animal from entering a restricted area whereby, an ultrasonic transmitter is worn by the animal and a receiver with an alarm output is placed in a stationary location to sound an alarm chasing the animal from the area in which the receiver is placed; a remote pet training device whereby a hand held transmitter is carried by a human trainer and a receiver unit is worn by the pet, the receiver produces a set of training tones in response to the modulated ultrasound produced by the transmitter; and a remotely operated pet door which automatically opens under its own power when it receives a signal from an ultrasonic transmitter worn by a pet.

TL;DR: In this article, a controllable animal access system is described, where a motion detector associated with a reader detects an encoded pet tag worn by a selected animal and actuates locking and unlocking mechanisms in response to reading an accepted code.
Abstract: A controllable animal access system connectable to the door of a building which has an opening covered by a pivotally moveable animal door. The animal access system has a motion detector associated with a reader which detects an encoded pet tag worn by a selected animal and actuates locking and unlocking mechanisms in response to reading an accepted code. Various other controls are provided for operation of the apparatus.

TL;DR: In this paper, an automatic pet door system is described, where a rectangular frame is mounted between studs of a wall defining a passage for entry and exit of a pet, and a door slides within the frame between a lower closed position for closing the passage and an upper open position for opening the passage.
Abstract: An automatic pet door system is disclosed. The automatic pet door system has a rectangular frame mounted between studs of a wall defining a passage for entry and exit of a pet. A door slidably moves within the frame between a lower closed position for closing the passage and an upper open position for opening the passage. The door is lifted by a drive means having a motor pulling a cable attached to the door. The motor is energized by a control means in response to a signal received from a magnetic transmitter worn by a pet when the pet approaches the door. A locking means prevents movement of the door upwardly from the closed position unless the door is moved by way of the drive means.

TL;DR: In this article, a panel for securing in a conventional sliding door opening to cooperate with the sliding doors therein has a swinging door flap at the bottom of a panel defined by vertical stiles which may be trimmed to suit varying door frame heights and which can be adjusted in width in one embodiment by breaking away segments of the stiles.
Abstract: A panel for securing in a conventional sliding door opening to cooperate with the sliding doors therein has a swinging door flap at the bottom of a panel defined by vertical stiles which may be trimmed to suit varying door frame heights and which may be adjusted in width in one embodiment by breaking away segments of the stiles. The stiles bear fixed projections to fit horizontal apertures at the door stile and sliding projections to fit aperatures in sill and top rail of the frame. The panel has an adjustable rail which overlaps the weather pane of the panel at top or bottom of the pane. The access door flap swings from an intermediate rail which may be a part of a panel or part of a sub-assembly mountable in any opening. The flap has imbedded magnets to arrest it closed and thin wiper edges to seal against weather, and is self-hinging in the intermediate rail. In one embodiment a vertically movable sill in the bottom rail rises to meet the lower edge of the flap in the closed position.

TL;DR: In this article, a pet door comprising a flap defining a pet access opening, a door flap pivotally mounted in the opening about a pivot axis located at an upper edge of the door flap, a latch mechanism to bar the door from opening in at least one direction, and a control mechanism for disabling the latch mechanism, the control mechanism including an infrared radiation detector which is mounted above a lower edge of pet access, defines a downwardly directed receiving zone for infrared radiation.
Abstract: A pet door comprising a flap defining a pet access opening, a door flap pivotally mounted in the opening about a pivot axis located at an upper edge of the door flap, a latch mechanism to bar the door flap from opening in at least one direction, and a control mechanism for disabling the latch mechanism to permit the door flap to open in the said at least one direction, the control mechanism including an infrared radiation detector which is mounted above a lower edge of the pet access opening and defines a downwardly directed receiving zone for infrared radiation.
