  • Patent number: 8893658
    Abstract: A method and system that controls pet access to various different locations and/or objects. In a preferred embodiment, the present invention provides an automated system whereby pets wearing an ID tag are allowed access to various locations and/or objects, such as food contained within a feeder dish for example, while a sensor system, responding to the presence of other animals or people, causes the device to close preventing unauthorized access thereto. The feeder further includes one or more sensors using ultrasonic, infrared technology or both in combination for the identification of both tagged and non-tagged animals or children. Further embodiments employ the system to control access to litter boxes, pet toys, pet watering systems, pet gate access, pet containment systems or pet doors.

  • Patent number: 7469657
    Abstract: An apparatus and method for selectively controlling an animal or pet's access to food is provided by a platform that moves with relation to a base. A lever is connected between the chassis of the platform and the base, whereby parallel movement of the chassis towards the base causes an arm of the lever to engage a door adapted to prevent access to the food. An opposing force is provided and preferably adjustable by the user so the user can set the weight sufficient to cause movement between the platform and the base. The device can be constructed either to prevent access or to allow access to the food upon movement of the platform.

  • Patent number: 7458336
    Abstract: There is disclosed an animal identification, feeding and entry control system based on a radio frequency identification (RFID) system including an animal collar-mounted RFID tag, and RFID circuitry including a single antenna housed within a bezel placed forward of and surrounding the entry aperture to optimize signal reception. The bezel shape allows only one animal to enter at a time. To conserve power, the circuitry is only activated when an animal pushes against a door within the device, triggering a switch mechanism. A circuit-controlled latch prevents animals from opening the door unless a code match is detected between the programmed code in the tag and a stored code in the circuit controlling the system. Multiple codes may be stored for identifying multiple animals wearing collars tagged with unique identifying codes. The system's applications include but are not limited to controlling animal entry to feeding enclosures, human housing and animal housing.

    Abstract: An automated feeding system for pets with special diets includes a feeder dish which is made accessible to a pet only when an ID tag on the pet is recognized as authorized by a receiver on the device and only for a certain time period. The appropriate amount of food is thereby made available at appropriate time intervals. If a plurality of tags is pre-programmed as authorized, each animal's tag can sequentially activate the feeding device to feed each animal, respectively. However, if more than one authorized tag is present in the feeding time set for one animal, the drawer closes.

  • Patent number: 7395782
    Abstract: A system and method for providing access to animal food utilizes identification tags on domestic animals, generally attached to a collar. The identification tag generates a signal that is detected by a receiver mounted on an enclosed food container. When the receiver detects a pre-selected acceptable signal from an animal, it activates a motor that causes a movable portion of the container to move to an open position. If the signal is no longer detected by the receiver, it activates the motor to move the movable portion of the container to a closed position. If the receiver detects a signal from an identification tag that is not one of the pre-selected signals, it activates the motor to move the movable portion of the container to a closed position.

    Abstract: A livestock feeder particularly suited as a horse feeder. This feeder has a grille on a front face and hangs on an outside of an enclosure with the front face resting on horizontal bars of the enclosure. The animal is able to pull feed through the vertically disposed grille on the front face. With the feeder on the outside of the enclosure, it is easily accessible for cleaning, filling with feed, or relocation while providing safe access on the outside of the enclosure. The feeder also allows a horse to eat at a natural gazing position by having a lower portion of the grille located near the ground. By providing feed at a natural grazing position, the feeder prevents gorging, boredom and waste while allowing the horse to feed with its head lower than its heart.
