Title: Methods for sheet scheduling in an imaging system having an endless duplex paper path loop
Inventor: FARRELL MICHAEL E
IPC: G03G21/00
Filed: 1991-07-09
Granted: 1996-03-12
Abstract: Methods for scheduling sheets in an imaging system having an endless duplex paper path loop are disclosed. Preferably,  the  duplex  loop  includes  a  single  sheet inverter without a buffer tray so as to eliminate the problems associated therewith.  The basic method involves consecutively inserting copy sheets to be imaged into the duplex loop without placing any skipped pitches therebe-tween regardless of set or job boundaries.   Duplex side ones from subsequent sets or jobs are used to fill any gaps which exist in the duplex side one sheet stream of earlier sets or  jobs.   Additional refinements  include using simplex sheets to fill potential skipped pitches in a  duplex side  one  sheet  stream  by converting  simplex sheets located immediately subsequent to the duplex sheets into duplex sheets having a blank back side and scheduling the side one imaging of the now-converted duplex sheets into the potential skipped pitches.   Potential skipped pitches can also be filled by shifting an appropriate number of simplex sheets at a simplex-to-duplex transition into  any  potential  skipped  pitches  in  an  immediately subsequent duplex side one sheet stream.  Further refine-ments include using duplex or simplex sheets to fill gaps which exist in a duplex side two sheet stream due to skip requests which occurred during the side one scheduling, inserting or imaging.

Title: Contact component
Inventor: STOERK PETER
IPC: H01T4/06
Filed: 1991-09-26
Granted: 2001-08-28
Abstract: Contact component. Attached to a base part (5), the contact component (1) has a clamping adapter (3) and a fork spring contact (6) with which it can be plugged onto pin-shaped mating contacts (14, 15, 16). With respect to an axis of symmetry, proceeding in plug-in direction, of the fork spring contact to be contacted with the mating contact, an offset (v1 or v2) is provided for a clamping point (4) of the clamping adapter (3) in a first direction proceeding perpendicularly to the axis of symmetry and in a second direction proceeding perpendicularly to the first direction and to the axis of symmetry (2). Each contact component (1) is firmly inserted in various positions in a base housing part. This occurs in reception chambers which are provided in the shape of a grid at a certain dividing distance.      The insertion in various positions of the contact components (1) provided with the offset enables the generation of contact configurations for the contact pins of electrical modular units or components which deviate from the arrangement of the reception chambers. For example, component contact pins arranged in one line can be converted to a mating contact arrangement aligned in a triangular shape. Generally, a conversion from a line to a grid is possible, or respectively, from a one grid to another grid with a different spacing. This feature also encompasses the expanding of two pin rows having a preset distance to two pin rows having a large distance from one another and vice versa.

Granted: 1997-01-14
Abstract: A method and a device in an elec-tric power network (1), comprising an active filter (4) controllable via a control input (41), for reducing disturbances generated by a disturbance source (6) lo-cated in and/or connected to the power network. A control member (8) is adapt-ed, based on at least one first state var-iable (Y1i) sensed in the power network (1) and a model of the power network (1), to calculate the disturbances (X2) which occur in a second section (B-B) in the power network (1) without action from the active filter (4), to calculate a control signal (C1) such that, supplied to the control input (41), it would gen-erate in the second section (B-B) the cal-culated disturbances (X2) with reversed polarity, and to generate the control sig-nal (C1) and supply this to the control input (41). By sensing, in addition, at least one second state variable (Y2i) in the second section (B-B), the control sig-nal (C1) can also be generated in depen-dence on the control deviation (DU) of the second state variable (Y2i) from a desired value (Y2R).

Title: Method and apparatus for communicating interleaved data
Inventor: PAIK WOO H
IPC: H03M13/33
Filed: 1993-06-18
Granted: 1999-08-31
Abstract: An interleaves (34) processes information in a pseudorandom order to provide pseudorandom interleaved data for communication to a deinterleaver (42). The pseudorandom interleaved data is processed at the deinterleaver (42) in a pseudorandom order corresponding to that used at the interleaves (34) means, to recover the original information. The pseudorandom processing at the deinterleaver is synchronized with the pseudorandom processing at the interleaves on a trial and error basis. In one embodiment, full synchronization occurs when a Viterbi decoder (44) receiving data from the deinterleaver has a renormalization rate within a designated threshold and when enough synchronization words are detected in data output from the deinterleaver to meet a predetermined criterion. In another embodiment, a timer is used to initiate a new starting address for the pseudorandom processing at the deinterleaver during successive time intervals. Synchronization is achieved when a start address is found that results in the detection of enough synchronization words in data output from the deinterleaver to meet a predetermined synchronization criterion.

Abstract: A mapping is produced from an object model to a relational model including specifying the search area by preparing subgraphs to specify a semantic query, applying the specifying step by using subgraph isomorphism to determine a set of matches of a set of nodes between the subgraph and the object model, and mapping particular information of the matched nodes (typically stored in the form of data) to the relational model. A reporting is produced to describe the relations between the nodes in the object model which is translated to the relational model along with the specific data contained therein. Using the results of the reporting as well as the specific data, the information contained in the relational model may be mapped into a second object model with the relations between the nodes created by the reporting.
