Abstract: A master movie and player are created on the fly. The master movie is created based on characteristics of a movie or other asset to be viewed by the player. The player is constructed from a template having rudimentary player capabilities for a predetermined connection speed. Tracks selected by suppliers and user/e-tailers are added to customize the player. Different players are constructed for various predetermined connection speeds. When an asset is to be viewed, a server downloads the master movie matching a content viewer's request to the content viewer's machine. The master movie determines the connection speed and send a message back to the server. The server then downloads the player for the asset requested by the content viewer and matching the content viewer's connection speed. The requested asset is then streamed to the content viewer.

Abstract: A personal computer (PC) system determines a demand usage value at a predetermined time for a load powered by an electric power system. The computer system includes a database for storing energy usage values and time values; a PC software logging routine for acquiring the values of energy consumed from the electric power system by the load, for determining corresponding time values for times at which the energy was consumed by the load, and for storing the energy usage values and time values in the database; and a PC software calculation routine for retrieving a predetermined count plus one of pairs of those values from the database, with one of the time values corresponding thereto being about equal to the predetermined time.

Abstract: The trip curves of circuit protection devices in an electric power distribution system are individually adjusted and coordinated in a hierarchy of protection devices by graphical manipulation, such as by dragging with a mouse, segments of the trip curves presented on a display device. The existing parameter settings can be provided to the display device and the adjusted parameter settings returned to the protection devices manually, but preferably, a communications network provides automatic transfer of the settings in both directions.
