Abstract: Apparatus and methods of identifying potentially similar content include utilizing workflow metadata to identify potential similarities in content to be processed, or between content to be processed and known content. As a result, a subset of potentially similar content is identified, and the subset can be used in data reduction operations to reduce data in the content to be processed.

Abstract: A method and apparatus for conferencing among a plurality of computers is described. A local user receives inputs containing user actions and data for interpretation as to what the user action is with respect to the data and produces user action outputs. An interpreter/encoder interprets and encodes the user action outputs into packets of encoded commands and data related thereto. A communications device sends the encoded information to at least one remote user and the local user itself. An interpreter decoder at each computer interprets and decodes the encoded information specifying an operation to be performed on the data. The operation is then executed at the local user and the remote users. The system is operating system independent and multiple documents and applications may be worked on at the same time by different users.

Abstract: Ocean thermal energy conversion (OTEC) uses a fluid, such as ammonia, hea by high-temperature surface water to provide a turbine-driving working gas. To condense the gas for re-use, a slurry of phase-transformation particles and cold ambient sea water is mixed in a deeply-submerged tank and delivered to a surface tank essentially at the cold sub-surface temperature. Condensing of the working gas is performed at the ocean surface level by exposure to the cold slurry temperature. Particle phase-transformation, which occurs at a temperature between that of the cold sub-surface water and the reject temperature of the heat-exchanger, maintains a surface tank temperature at about that of the sub-surface water.
