Abstract: A method and system of automated remote collaborative learning broadcasting. A computer-based server receives a plurality of video feeds for a remote interaction. Server receives unique user identifier and bandwidth of unique user viewing a remote interaction. Unique user is identified based upon bandwidth connection as either active or passive. Local audience viewers receive the plurality of video feeds and may select a video feed among the plurality of video feeds. Local audience viewers may seamlessly switch between the plurality of video feeds based upon individual preference. Server tracks local audience viewer's video feed selection. Remote audience viewers receive single video feed determined by local audience viewer selection. Minimum video switching time must be met before switching single video feed to a new view. Video threshold automatically switches video feed based upon prolonged static view if predetermined criteria is met.

Abstract: The invention provides a method of depositing a buffer layer or film onto a surface of a substrate. The method includes providing the substrate in a controlled atmosphere and exposing the substrate to a vapour comprising a film forming species. While the substrate is exposed to the vapour, two or more ion beams are provided incident upon the surface of the substrate to assist formation of the film. The respective axes of incidence of the two or more ion beams are distinct and are selected and controlled in order to maintain the arrival rate ratio, maximise the deposition rate, and maximise the biaxial alignment of the layer so formed.
