Abstract: A gyro-stabilized automatic pet door is installed in a hinged door and is actuated by a magnet worn by a pet. The automatic pet door prevents unintended openings caused by the Earth's ambient magnetic field that may trigger a magnetic detector that responds to the magnet worn by the pet. A microelectromechanical systems gyro disposed on the hinged door generates a signal in response to a movement of the hinged door that engages a lockout timer overriding the signal from the magnetic detector and preventing the pet door from opening.

Abstract: An electronic article surveillance (EAS) system comprising a combined plurality of surveillance systems that operate independent of and autonomous from each other and are physically located within pedestal systems having at least a first EAS system for detecting a magnetic EAS tag (which are immune to foil lined bags and other Faraday Shields) and magnetic detachers, a second EAS system for detecting Faraday shields, a third EAS for detecting acousto-magnetic EAS tags, and an anti-EAS jamming alarm mechanism. The EAS system of the present invention further includes a counter that counts the number of individuals entering into and exiting out of a secured area, and validate if an alarm is legitimate.
