  • Publication number: 20070047837
    Abstract: A stereo imaging based vision system and method provides enhanced portal security through stereoscopy. In particular, a system detects non-people objects within the chamber of a revolving door by acquiring two-dimensional (2D) images from different vantage points, and computing a filtered set of three-dimensional (3D) features of the door compartment by using both the acquired 2D images and model 2D images. Applying image processing techniques to the filtered 3D feature set, non-people objects can be detected.

  • Publication number: 20050249382
    Abstract: A method and system provides increased levels of security for a mantrap portal by continuously monitoring two zones of the mantrap; a primary zone and a secondary zone. A primary sensor determines that exactly one or zero people are present in the primary zone when requesting access into a secured area. A secondary sensor determines that exactly zero people are present in the secondary zone when access to the secured area is granted. The primary and secondary sensors in combination can detect piggyback events and tailgating events before granting access to a secured area. Further, the primary and secondary sensors in combination can detect the presence of unauthorized persons in a mantrap prior to granting access to the mantrap for exit from a secured area.

  • Patent number: 5806708
    Abstract: A pressure tight travel case for airline passengers for use in the unpressurized baggage compartment of an aircraft, comprising a container having side walls and a bottom defining an opening and a cavity; a first partition removably insertable within the cavity, wherein the first partition includes opposing side edges, a top edge and a bottom edge; and a cover matable with the container to close the cavity, the cover including a sealing device for creating a seal between the cover and the container sufficient to prevent pressurized air within the container from leaking through the sealing device during flight. The travel case further includes guiding grooves for guiding the insertion of the first partition into the cavity, and wherein the opposing side edges of the first partition are formed to matably engage the guiding grooves.
