Abstract: A method and system is provided that controls access to various different locations and/or objects whereby animals wearing an ID tag are reliably and consistently allowed or denied access to various locations and/or objects, such as food contained within a food delivery device dish for example. An RFID system that employs a internally powered RFID tag with inductively coupled transmissions where a reader is employed linked to an internal multiple antenna array that is focused on all possible animal approach directions for a range of up to 36?, but not more.

Abstract: The disclosed invertible structures rely on combinations of translational movements to effect inversion. An exemplary invertible structure includes a track operable to be slidably coupled to at least two connectors of a longitudinal structure. The track may have a slot having a plurality of translational axes for translational movements of the connectors of the longitudinal structure that would effect the inversion of the longitudinal structure.

Abstract: A method and system is provided that controls pet access to various different locations and/or objects. In a preferred embodiment, the present invention provides an automated system whereby pets are identified by sensors and allowed access to various locations and/or objects, such as food contained within a feeder dish for example. The feeder further includes a door structure and control system that keeps the pet safe through the use of a door which is made up of several repeated panels which together move to cover the food when access is not allowed and having a jam sensing system in order to protect pets from being caught in the closing door. 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.
