A computer based scheduling and rescheduling method, apparatus and system for an electronic calendar. The electronic calendar illustrates a time progression of scheduled tasks in a horizontally or vertically oriented view of time. The electronic calendar and its graphical user interface (GUI) provide a viewing pattern for the user. Direction in the viewing pattern is synonymous with increasing/decreasing dates-times in the time progression of scheduled tasks. A scheduling-rescheduling engine schedules into the calendar user requested tasks and automatically reschedules impacted previously scheduled tasks. The scheduling-rescheduling engine also schedules user selected resources (e.g., people, robots, tools, etc.) per scheduled task.

Computer method and apparatus for automated scheduling

An absolute linear encoder includes an index channel and at least two counter channels. The spacing between markings on the index channel is constant, and the spacing between markings on the first and second channels is predetermined so that the positions of the markings in the first and second channels vary so as to provide a unique signature for each position along the encoder. The linear encoder includes quadrature channels to provide increased resolution and to determine the direction of translation. The encoder is provided with a detector unit to detect positions of the markings in each channel, and a processing unit to calculate an absolute position from the detected marking positions. A method of producing the absolute linear encoder includes selecting spacings for markers in the quadrature, index, first and second channels in order to provide a desired resolution and encoder length.
