Abstract: Systems and methods for communication. A network abstraction layer (NAL) is built on a public Internet, the NAL comprising an overlay network allowing a direct Internet Protocol (IP) communication between endpoints in a virtual private network (VPN) over the Internet. A network virtualization layer (NVL) is built on the NAL, the NVL comprising a VPN aggregator using DGOI protocol encryption, providing synchronization of session keys to encrypt a payload between all the endpoints over the NAL such that encrypted traffic is able to be decrypted by any endpoint for an entire session to allow instantly available communication between all the endpoints.

Abstract: A method, apparatus and article of manufacture for building next generation improved regional virtual private networks over the Internet. The method comprises of building two layers on top of the public infrastructure (001): a network abstraction layer (NAL) (002) and a network virtualization layer (NVL) (003): the NVL (003) is built on top of the NAL (002). The NVL (003) consists in Group Domain of Interpretation (GDOI) domain deployments on virtualized hardware aggregators over a NAL (002). The latter consists in point-to-multipoint Generic Routing Encapsulation (GRE) networks over the Internet (001). Both the NVL (003) and NAL (002) can be deployed using advanced unattended provisioning methodology.

Abstract: A positioning device for positioning a movably mounted portion of a workpiece. The positioning device includes an attachment structure, a rod, a flange assembly and an engagement mechanism. The attachment structure includes a rod aperture and is coupled to a robotic apparatus. The rod is disposed within the rod aperture and is slidably positionable therein. The flange assembly is coupled to a distal end of the rod and includes a flange structure. The flange structure is rotatable relative to the rod and engages the movably mounted portion of the workpiece. The engagement mechanism is coupled to the attachment structure and is operable for moving the rod in an axial direction within the rod aperture. The engagement mechanism applies an axially directed force to the flange assembly to maintain the flange structure in a stationary position relative to the movably mounted portion of the workpiece when the movably mounted portion of the workpiece is moved relative to a remaining portion of the workpiece.
