Abstract: A personal computer that enters sleep mode to conserve electrical energy is responsive to a proximity detector and a proximity timer. As long as a user is near the computer, as determined by the proximity detector, the computer is controlled by an activity timer, and enters sleep mode upon being idle for a predetermined period of time. When the proximity detector determines that the user has left the computer unattended, the proximity detector starts the proximity timer. When the proximity timer expires, the computer enters sleep mode. Because the proximity timer operates only when the user has left the computer unattended, the proximity timer may be set to expire earlier than the activity timer. Consequently, the computer may enter sleep mode earlier than would otherwise be possible, and thereby consumes less energy.

Abstract: A method, apparatus, and article for solving the year 2000 problem involves limited modifications in the data definition portions of the source code and compiler support for processing the modified source code. Fields in the source code that contain a year or date values are identified and, for each such field, the user selects an appropriate technique (for example, expansion, compression or windowing). The user modifies the data definition for each identified field, by adding new attributes to request the selected technique. The user then compiles the program and resolves any ambiguous references to the variables whose definitions were modified. This procedure is applied, module by module, and each processed module is merged into production, after testing, by using a compiler option to disable the use of the new attributes.
