First Claim
1. An animal feeding device having electronic identification and feed control comprising:
- an enclosed feeding chamber having a single aperture therethrough permitting animal entry into said feeding chamber;
a bezel attached about said aperture and extending outwardly therefrom and substantially transversely thereto with an interior volume of said bezel defining a single entryway into said feeding chamber, said entryway dimensioned for entry into said feeding chamber by only one animal at a time, of an intended size range;
a door having a pivotal attachment within said feeding device in proximity to said aperture, said door having a closed position blocking said aperture;
said door in said closed position defining the length of said entryway and thus the length of said bezel;
said length of said entryway and said length of said bezel being at least equal to a length measured from the shoulders of said animal forward to the tip of the nose of said animal, and no longer than the total length of said animal;
said door further being pivotally attached to said feeding device in proximity to the upper boundary of said aperture;
said door being upwardly and inwardly pivotable into said feeding chamber if unlocked and pressed upon from outside said feeding chamber;
said door further comprising an upper substantially flat portion and a lower curved portion joined together, said lower curved portion curving inwardly towards said feeding chamber with a radius of curvature between 18 mm and 65 mm, spanning an arc section of between 30 degrees and 75 degrees, thereby when said door is upwardly and inwardly pivoted, said lower curved portion preventing objects from catching on said door;
locking means for locking and unlocking said door and operable between a locked condition and an unlocked condition, said locking means, with said door closed, operable to a locked position and, with said lock in an unlocked condition enabling said door to be opened;
radio frequency identification (RFID) sensor means configured to function cooperatively with an RFID-tagged animal;
said RFID sensor means including at least one antenna element positioned forward of said aperture and formed into at least one loop to circumferentially surround said entryway; and
said RFID sensor means actuating said locking means thereby permitting access to said feeding chamber by said RFID-tagged animal.

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.

21. An animal feeding device having electronic identification and feed control comprising:
-
an enclosed feeding chamber comprising one or more chamber walls rising substantially vertically, said one or more chamber walls having a single aperture therethrough permitting animal entry into said feeding chamber, said feeding chamber being a single compartment dimensioned to prevent complete entry by animals of an intended size range; a base having a perimeter in detachable mechanical communication with said one or more chamber walls; said detachable mechanical communication comprising at least one mechanical latch; said base further shaped at least in part to retain nutritional materials and capable of holding means for cooling said nutritional materials; a roof portion disposed atop and disposed contiguous with the upper edges of said one or more chamber walls, said roof portion further including a portion made of transparent or translucent material thereby permitting the entry of light into said feeding chamber; a bezel attached about said aperture and extending outwardly therefrom and substantially transversely thereto with an interior volume of said bezel defining a single entryway into said feeding chamber, said entryway dimensioned for entry to said feeding chamber by only one animal at a time, of an intended size range; said feeding device preferably formed of injection-molded plastic or low cost, easily formed and durable material, and wherein at least a portion of said feeding device includes airholes providing ventilation and permitting the odor of any nutritional materials contained within said feeding chamber to outwardly propagate; a door pivotally attached within said feeding device in proximity to the upper boundary of said aperture, said door having a closed position substantially blocking said aperture, said door upwardly and inwardly pivotable into said feeding chamber if unlocked and pressed upon from outside said feeding chamber; said closed position configured to orient said door to slope inwardly towards said feeding chamber from said pivotal attachment; said door further comprising an upper substantially flat portion and a lower curved portion joined together, said door further having an inward surface substantially facing said feeding chamber and an outward surface substantially facing away from said feeding chamber; said lower curved portion curving inwardly towards said feeding chamber with a radius of curvature between 18 mm and 65 mm, spanning an arc section of between 30 degrees and 75 degrees, thereby when said door is upwardly and inwardly pivoted, said lower curved portion preventing objects from catching on said door; a latch in mechanical communication with said door and operable between a locked condition and an unlocked condition, said latch, with said door closed, operable to a locked position and, with said latch in an unlocked condition enabling said door to be opened; said door in said closed position defining the length of said entryway and thus the length of said bezel; said length of said entryway and said length of said bezel being at least equal to a length measured from the shoulders of said animal to the tip of the nose of said animal, and no longer than the total length of said animal; a solenoid in mechanical communication with said latch, said solenoid operating said latch between a locked condition and an unlocked condition; radio frequency identification (RFID) sensor means configured to function cooperatively with an RFID-tagged animal, said RFID sensor means actuating said solenoid thereby permitting access to said feeding chamber by said RFID-tagged animal; said RFID sensor means further including at least one antenna element, said antenna element positioned forward of said aperture and formed into at least one loop to circumferentially surround said entryway; a switch in mechanical communication with said door, said switch actuated by pressure against said outward surface of said door, said switch further in electrical communication with said RFID sensor means; wherein at least a portion of said RFID sensor means further has at least two operational states wherein the first operational state is a minimum-power sleep state and the second operational state is an active state enabling full function of said RFID sensor means; wherein said minimum-power sleep state draws a nonzero but minimum amount of power; wherein the default operational state of said RFID sensor means is said minimum-power sleep state thereby providing minimum power consumption for said system; wherein said RFID sensor means is further configured such that if said switch is actuated then said RFID sensor means is brought out of said minimum-power sleep state into said active state, said RFID sensor means further including timekeeping means such that after an increment of time from an event such as the actuation of said switch, said RFID sensor means returns to said minimum-power sleep state, thereby conserving power.
