Abstract: A communication device. The communication device comprises a central processing unit (CPU), a graphics processing unit (GPU), and a non-transitory memory comprising executable instructions for a sharing application that when executed by at least one of the CPU or the GPU, causes the sharing application to transmit an executable of a trusted application to an endpoint communication device, begin execution of the sharing application in a trusted security execution zone (TSZ) execution mode for sharing media content, instantiate a trustlet application that begins execution by the CPU or the GPU in the TSZ execution mode, display a unit of media content on the communication device, determine whether the unit of media content comprises confidential information, and in response to a determination the unit of media content comprises confidential information, transmit commands to the trusted application to control one or more functions at the endpoint communication device.

Abstract: A portable personal wireless interactive video device including a miniature camera, a portable wireless transmitter connected to the camera, a portable wireless receiver for receiving video signals from the transmitter, and a portable video display device connected to the receiver for presenting an image to a viewer corresponding to a view from the perspective of the camera. The viewer may select an image for display on the video display device corresponding to a view from his/her own camera, from a camera worn by another person, or from one of several cameras positioned in selected locations. In one embodiment, the camera may be located within a remotely controlled model vehicle, thereby providing the viewer with a view from the perspective of inside the vehicle for viewing while remotely controlling the vehicle.

Abstract: An actuator for opening and closing the gate of a surface safety valve includes a primary piston and an auxiliary piston. The primary drive piston is directly connected to the valve stem, while the auxiliary piston is slideably connected thereto. Extension movement of the auxiliary piston is stopped by a divider plate after initial breakaway forces are overcome. The thrusting force developed by the auxiliary piston during a valve opening operation is transmitted to the valve stem and the primary piston by a shuttle sleeve. The shuttle sleeve is radially spaced about the valve stem, thereby defining a bridge annulus which maintains fluid communication between the primary pressure chamber and the auxiliary pressure chamber at all times. The thrusting force produced by the auxiliary piston is combined with the thrusting force produced by the primary piston to break the static gate seal and overcome the gate drag during a first stage of operation.
