Method And Apparatus To Drive Two-Phase Motors From A Three-Phase Bridge
view source
US Patent:

8552672, Oct 8, 2013
Filed:

Oct 17, 2011
Appl. No.:

13/274914
Inventors:

Thomas John Bucella - Rochester NY, US
Dave Sewhuk - Rochester NY, US
Scott Mayne - Webster NY, US
Warren God - Fairport NY, US
Assignee:

Teknic, Inc. - Pittsford NY
International Classification:

H02P 6/14
US Classification:

31840027, 3184002, 31840026, 31840029, 318722
Abstract:

A motor drive for driving two-phase motors using a three-phase bridge output stage, and a method of operating the drive. The driven two-phase motor can be a two-phase bipolar motor (such as a hybrid stepping motor). The drive can also be configured so that a single output stage can be used to drive either two-phase or three-phase motors, with or without a feedback sensor. A reference return is provided from one of the three half-bridge output stages with each of the motor phase windings connected between the reference return and one of the other half-bridge outputs. The switches of each half-bridge are modulated so that current can be controlled in each of the two motor phase windings.

US Patent:

20090225369, Sep 10, 2009
Filed:

Mar 7, 2008
Appl. No.:

12/043978
Inventors:

GERALD S. GORDON - Rochester NY, US
John H. Gustke - Walworth NY, US
Scott Mayne - Rochester NY, US
Assignee:

Xerox Corporation - Norwalk CT
International Classification:

G06K 9/00
US Classification:

358 118
Abstract:

What is provided are a system and method for print/copy job environments utilizing a page description language (PDL). In one embodiment, an input PDL stream describing embedded objects in a job is received and parsed. Reusable document components (RDCs) are identified. A determination is made as to how many placements are in the PDL for each identified RDC. If no RDCs are placed more than once, caching is disabled. If it is not efficient to split the PDL stream into smaller tasks, page parallel rip (PPR) is disabled. The embedded objects are analyzed to determine a number of PPRs for the job based on system resources. A raster image processing (RIP) time is projected for each path in the job based on the determined number of placements and the determined number of PPRs. A job processing path is prescribed for the job based on the most efficient projected RIP time.

US Patent:

20140077749, Mar 20, 2014
Filed:

Mar 8, 2013
Appl. No.:

13/790926
Inventors:

David W. Sewhuk - Rochester NY, US
Scott M. Mayne - Webster NY, US
Assignee:

TEKNIC, INC. - Pittsford NY
International Classification:

H02P 8/38
US Classification:

318696
Abstract:

An apparatus or method which accepts a burst of pulses at a frequency which may not be tightly controlled and converts this into a trajectory command that is a suitable motion profile for an incremental motor control application. The output of the invention can be a pulse stream that can be fed to an existing incremental pulse input motor drive or the invention can be embedded into a motor drive where its output is a numerical sequence that defines a physically realizable trajectory to be fed to the control circuits and software within the motor drive.
