Abstract: A multimedia collaboration system comprises client devices that include user interfaces that comprise private workspaces that can be used to display a live history of a multimedia collaboration session. The private workspaces can be configured to display information representative of media elements that can be shared within the multimedia collaboration session, but that are only viewable to a participant associated with a particular client device. The private workspaces can be used to preview information before publishing it to other participants or to view a live history of the multimedia collaboration session.

Abstract: A collaborative communication system comprises a highly flexible architecture that facilitates connecting communication devices and networks to establish multimedia collaboration sessions in a manner that allows distribution of various services and features throughout the collaborative communication system to provide scalability and selectable combination of cost, resource usage, and performance.

Abstract: Systems and methods for dynamically configuring and optimizing a multimedia conference session. An exemplary method of the invention may include providing a plurality of services to be used in the multimedia conference session, wherein each of the plurality of services may be hosted by and independently executable through at least one service endpoint in a communications network. Further, a plurality of users may be enabled to participate in the multimedia conference session. In particular, each user may participate in the conference session through a respective user endpoint in the communications network, where the respective user endpoint may be hosted by and independently executable through at least one service endpoint. Each service endpoint is configurable as an authentication service and a presence service such that the at least one service endpoint is operable to authenticate and publish a presence of each user endpoint.

Abstract: A simultaneous multiple rotation interface where a series of discs rotate about an eccentric camshaft. Each disc is engaged with the other by a series bearings embedded within each disc. As the camshaft rotates, each disc alternatively engages an outer shell so as to rotate the shell in the same direction as the shaft, albeit at a reduced speed.

Abstract: A multimedia collaboration system that facilitates more efficient, free-flowing collaboration sessions. The role of the presenter can be exchanged among participants in a collaboration session. The multimedia collaboration system is configured so that control of a collaboration session can be exchanged freely between participants in the collaboration session. The multimedia collaboration system enables participants in the collaboration session to determine the pace and course of the session.

Abstract: The present invention is directed toward an apparatus for continuous speed variation of an output member with respect to a primary input member. In particular, the present invention provides a device having an output that rotates at reduced speed and increased torque relative to its prime input through the low friction, rolling engagement of its members, or alternatively, at increased speed and reduced torque for overdrive applications. Furthermore, the speed of the output member may be varied continuously and infinitely between the apparatus's lowest and highest ratio via a secondary input member and its low friction, rolling engagement with the device's members.

Abstract: A method for capturing energy from mechanical actions associated with recovery of underground fluids, and for improving the economic feasibility of low producing, but viable, oil wells. The present method captures energy associated with an oil well pump device and waste water as each fall under the influence of gravity. This energy is converted into a premium form, stored in an easily verified and metered form, and sold on a market, in accordance with a legislative scheme.

Abstract: A wear assembly for protecting a structure, such as an excavating bucket, from wear includes a lock for securing the wear member in place. The lock includes a take-up element for tightening the fit of the wear member, a latch to retain the lock in the assembly during use, and an arrangement for resisting loosening of the lock. With the assembly, the lock is able to effectively tighten the fit of the wear member on the lip, resist loosening of the fit, and facilitate easy removal of the lock without a concomitant increased risk of lock ejection.

Abstract: A source communication device comprises a cluster manager to group destination device connections into a plurality of performance clusters. The cluster manager then causes a synchronization mechanism to be generated for each performance cluster. Each synchronization cluster can then allow data to be optimally shared between the source device and destination devices within a given cluster.

Abstract: A device for actuating a reciprocating recovery apparatus for recovery of underground fluid. The actuating device has a centrally aligned input component, that transversely receives an output component through a central aperture, and is engaged with a driving mechanism. Torque is increased about the central output component as a series of axially aligned, but centrally offset, lobes push a corresponding driver disc around the central output at reduced velocity and increased torque. Each driver disc moves in eccentric fashion, yet remains engaged with a corresponding, centrally aligned take off member, each of which is further in combination with the central output component.

Abstract: A collaborative communication system that includes a plurality of endpoints and interconnecting nodes configured to communicate via messages over interconnecting channels. Each of the plurality of endpoints and/or interconnecting nodes can determine whether to apply protection to the messages on a per message basis and/or base on the interconnecting channel being used. Thus, a balance between adequate protection and use of system resources and bandwidth can be maintained.

Abstract: An implantable vascular filter and method of implantation where the filter is deployed at or near an implantation site and is then radially expanded from its radially compressed configuration under the action of a force controlled remotely by a surgeon, such as by expansion of a balloon in contact with the filter or by applying a force on the filter with the introducer; the expansion is controlled using a means such as control wire, or fluid injector so that the filter adopts a filtering configuration and securely engages with a vessel wall.
