A computing device runs multiple activities concurrently and provides at least two modes for interacting with the activities. The user may toggle between the modes as desired. In a full-screen mode, one activity occupies substantially an entire display screen. In a windowed mode, the activity is visible within a window, and a portion of at least one other window is also visible. In the windowed mode, the user can cause windows to move, thereby changing focus from one activity to another. For example, the window having focus can be moved off the screen, to be replaced by a new window that is then given focus. The windows are ordered in a sequence and move in concert with one another; pushing one window off one edge of the screen causes a new window to appear at the opposite edge. A persistent positional relationship can be established among windows.

Additional aspects of the invention include devices and methods for delivering and deploying a radially expandable prosthesis.

A computer system is used to host a virtual reality universe process in which multiple avatars are independently controlled in response to client input. The host provides coordinated motion information for defining coordinated movement between designated portions of multiple avatars, and an application responsive to detect conditions triggering a coordinated movement sequence between two or more avatars. During coordinated movement, user commands for controlling avatar movement may be in part used normally and in part ignored or otherwise processed to cause the involved avatars to respond in part to respective client input and in part to predefined coordinated movement information. Thus, users may be assisted with executing coordinated movement between multiple avatars.

A coordinated action robotic system may include a plurality of robotic vehicles, each including a platform and at least one manipulator movable relative thereto. The robotic system may also include a remote operator control station that may include a respective controller for each manipulator. The remote operator control station may also include a mapping module to map movement of each manipulator relative to its platform.

The coordinated movement may result in increased operational efficiency, increased operational dexterity, and increased ease of controlling the robotic vehicles.

A spray apparatus comprises a housing having a fluid inlet, a plurality of tubes for dispensing fluid from the housing, and an integrating member operatively coupled to at least a subset of the plurality of tubes for effecting coordinated movement of the coupled tubes in response to movement of the integrating member. An actuator, such as a turbine or an adjustable control ring, is employed for inducing movement of the integrating member.
