Abstract: Computer program code receives input information for setup a video conference, and attributes of participants associated with one or more video endpoints in the video conference. The program code parses the input information to determine whether there are video data streams available for broadcast, and parameters in an access control file granting one or more of the participants a right to control which of the video data streams available for broadcast they view. The program code extracts parameters from the input information. The program code stores the parameters that are extracted as metadata. The program code compares the metadata with the attributes of the participants associated with the one or more video endpoints to determine matches. The program code requests a multipoint control unit to send one or more of the video data streams based on the access control file, criteria specified by the participants, and the matches determined.

Abstract: A method, computer program product, and system for identifying collaborators is described. A command precursor associated with delivery of a voice command associated with an electronic meeting is received. An audio signal including the voice command is received. A portion of the audio signal is identified as representing the voice command, based upon, at least in part, receiving the command precursor. The voice command is interpreted. The interpreted voice command is caused to be executed.

Abstract: Chemical vapor deposition reactions are carried out by introducing first and second precursors for the material to be deposited into a reaction chamber (5) along a plurality of separate discrete paths (21,24) where they are cooled prior to entry into the reaction chamber. The precursors are mixed in the reaction chamber which contains a heated substrate (4) and react to deposit the material on the substrate.

Abstract: Substrates on which vapor deposition is to take place are mounted on the outside of a generally bell-shaped susceptor which is itself mounted immediately outside a similarly shaped shield which is transparent to infra-red radiation. Infra-red lamps are mounted within the shield and the radiant heat from them passes through the shield and heats the substrates through the susceptor. An outer, opaque, shield defines an annular gas passage through which reactant gases pass over the heated substrate to cause vapor deposition thereon. Purging gas may be passed between the transparent shield and the susceptor. The lamps and the susceptor may be relatively rotated. The arrangement substantially eliminates the possibility of the reactant gas causing deposition on the transparent shield which would interfere with the passage of radiant heat to the susceptor and the substrate.
