Post-interventional neointimal hyperplasia in arteries is treated by the application of ultrasonic energy. Usually, an intravascular catheter having an interface surface is positioned at a target site in the artery which has previously been treated. The interface surface is vibrationally excited to apply energy to the arterial wall in a manner which inhibits smooth muscle cell proliferation in the neointimal layer.

Subscribers request programs from a network based content server and view the requested programs via their customer equipment. The content server receives various programs and breaks the program content for each program into a sequence of program segments, which are logically linked by program association indicia. The content server also receives advertisements and stores the advertisements as advertising segments, which generally contain at least one complete advertisement, but the invention is not limited thereto. Upon receiving a program request from a subscriber, the content server will identify advertising segments to provide along with the program segments for the requested program, and where to place the advertising segments among the program segments. Next, the content server will generate composite association indicia identifying the sequence of program and advertising segments, and effect delivery of the program and advertising segments to the subscriber in the sequence defined by the composite association indicia.

A method and implementing computerized system are provided for enabling the setting of automatic door opening limits for doors. In an exemplary embodiment, distance measuring transceivers, such as radar devices, are implemented in the doors of a vehicle to determine the distance between a vehicle door and nearby obstacles which may obstruct the full opening of the door. If the measured obstacle distance is less than the predetermined clearance distance required for a full opening of the door, then the maximum allowable distance for the door to open without encountering the obstacle is determined and limits are set to prevent the vehicle door from opening more widely than the maximum allowable distance. In one embodiment, the door opening is restricted by mechanical limits which are established by a gear-driven or rack-and-pinion system controlled by a limit control motor. The limit control motor is operable to position a mechanical door opening limiting apparatus in response to the measured obstacle distance to physically limit the extent to which the door is allowed to open. Visual and audio signals are also provided to communicate related messages to the driver and/or passengers of the vehicle. In one embodiment, the system may be disabled when an emergency situation is detected such as when the vehicle air bags are deployed.

A prosthetic foot (124) incorporates a foot keel (165) and a calf shank (126) connected to the foot keel to form an ankle joint area of the prosthetic foot. A device (125) connected between the upper end of the calf shank and the lower portion of the prosthesis can be used to assist posterior movement of the upper end of a calf shank and control anterior movement of the upper end of the calf shank during use of the prosthesis. The device (125) has springs which store energy during force loading with anterior motion of the upper end of the calf shank in gait and which, during force unloading, return the stored energy as kinetic power for adding to the propulsive force on the user's body generated by the prosthesis in gait.

A beverage container for the storage of a carbonated drink comprising a container body (10) including an opening (11) and removable closure means (12) for closing the opening (11), the closure means comprising a foil (20) which provides a gas tight seal for the opening (11). The arrangement may be such that a tendency of forces acting on the foil (20) due to pressure within the container to separate the foil (20) from the container body (10) by peeling away therefrom is reduced e.g. by the provision of a collar (12A) to limit deflection of the foil (20) adjacent the bond therebetween and/or by the shape of the rim (15) of the container body (10), so the closure is capable of withstanding higher internal pressures than would otherwise be the case.
