Patent ES-470846-A1 (ES)
Title: Positioning system employing feedforward and feedback control.
IPC: G05B13/02
Filed: 1978-06-16
Abstract: A positioning system for moving a member between positions in time optimal fashion employs concurrent "feedforward" and "feedback" control. The feedforward control system provides major control and the feedback control system provides minor control to correct for deviations between the actual and a nominal system. The feedback loop may thus be of low bandwidth permitting desensitization to high frequency disturbances or the employment of inherently low bandwidth controlled variables. The "feedforward" control function includes successive portions of opposite polarity corresponding to acceleration and deceleration of the member and also includes a subtractive velocity related component. This function represents the approximate current input to an electromagnetic coil actuator of a nominal system required to move such a member between positions in time optimal fashion.

Title: Computer system and method for page composing.
IPC: G06K15/00
Filed: 1984-04-10
Abstract: Machine-implemented text/graphics formatting is based upon a logical page area on a presentation-receiving medium, such as a CRT face, sheet of paper and the like. Named text and graphics receiving areas are selectively assignable to the logical pages of a document being formatted for visual presentation and are addressable and formattable independent of other formatting in any logical page. The named areas are machine defined such that one area can have portions thereof automatically assigned to and presented with any arbitrary number of logical pages. Such areas are managed in a text formatting machine to facilitate formatting headers based upon text contained in a succession of logical pages that are outside the named area. A first class of such named areas is placed upon the page when formatting to the page is ended, while a second class of such named areas is placed on the page in response to a command. The placement of the second class on a page can result in starting formatting new pages. Bleed tabs, annotations, and other typographic niceties are machine formattable using such named areas.
