Publication number: 20220317485Abstract: A spatial light modulator system includes a concentration layer including an array of optical concentrators, such that each concentrator concentrates a portion of an input light beam. A modulation layer includes an array of light modulators each in optical communication with one of the optical concentrators for modulating the portion of the input light beam. The light modulators are spaced apart from one another in the modulation layer to form gaps between adjacent ones of the light modulators. A coil of each light modulator can surround a Faraday element or core containing a Faraday material to control a magnetic state of a Faraday material responsive to control signals.Type: ApplicationFiled: June 13, 2022Publication date: October 6, 2022Inventors: Charles C. Partee, Kevin D. McKinstry, Michael G. Machado

Publication number: 20040153902Abstract: A serial flash integrated circuit is provided with an integrated error correction coding (“ECC”) system that is used with an integrated volatile page memory for fast automatic data correction. The ECC code has the capability of correcting any one or two bit errors that might occur on a page of the flash memory array. One bit corrections are done automatically in hardware during reads or transfer to the page memory, while two-bit corrections are handled in external software, firmware or hardware. The ECC system uses a syndrome generator for generating both write and read syndromes, and an error trapper to identify the location of single bit errors using very little additional chip space. The flash memory array may be refreshed from the page memory to correct any detected errors. Data status is made available to the application prior to the data. The use of the ECC is optional.Type: ApplicationFiled: January 21, 2003Publication date: August 5, 2004Applicant: NexFlash Technologies, Inc.Inventors: Michael G. Machado, Chris Van Genderen, Poongyeub Lee, Joo Weon Park

Patent number: 5633569Abstract: A method of driving a motor without initial back rotation includes the steps of identifying a rest position 22 of a storage medium 20, mapping the rest position of storage medium 20 to a motor drive sequence, and driving the motor with the motor drive sequence, thereby enabling motor start-up without back rotation. The method is applicable to unipolar and bipolar drive methods as well as inductive read type and magneto-resistive type heads.Type: GrantFiled: March 10, 1995Date of Patent: May 27, 1997Assignee: Texas Instruments IncorporatedInventors: James E. Chloupek, William R. Krenik, Michael G. Machado

Patent number: 5517631Abstract: A programmable data sequencer transfers fixed length data blocks between variable length storage segments of a magnetic storage disk and a buffer memory within a data storage device. The data sequencer includes a stack memory for holding user byte count values read from a header field preceding each data sector having variable length split storage segments. Each byte count value indicates respective length of a following variable length storage segment, so that the storage capacity of each segment is dynamically determined by the data sequencer in real time by popping the user byte count value from the stack into a storage segment length counter and by counting down the count value within the segment length counter.Type: GrantFiled: July 7, 1993Date of Patent: May 14, 1996Assignee: Quantum CorporationInventors: Michael G. Machado, Clifford M. Gold, Bruce R. Peterson, Daniel E. Barnard, James H. Do

Patent number: 5255136Abstract: A miniature disk drive achieves storage densities of at least approximately 1700 tracks per inch per storage surface of a storage disk defining a series of radially extensive servo sectors embedded within circumferential zones of data tracks. The sectors are recorded at a constant data transfer rate while each zone has a data transfer rate adapted to disk radius. The drive includes a head and head positioner, a read preamplifier for amplifying analog signals read from, and for amplifying signals to be written to, a storage surface.Type: GrantFiled: June 4, 1991Date of Patent: October 19, 1993Assignee: Quantum CorporationInventors: Michael G.

Patent number: 4730321Abstract: A rotating disk data storage subsystem is disclosed for recording and retrieving data in blocks of predetermined finite length, each block of data including an error correction code syndrome portion calculated in accordance with a predetermined Galois field error correction algorithm. The subsystem includes a data controller including a unitary, cyclic error correction code syndrome generator/decoder for processing each incoming byte of the block in accordance with the said error correction algorithm in a manner which tests for the presence of any errors and which generates error values from which the errors may be located and corrected. A microprocessor controller has access to the data controller for testing to determine if the generator has determined the presence of an error for an incoming block, and if so, for obtaining the error values.Type: GrantFiled: May 30, 1986Date of Patent: March 8, 1988Assignee: Quantum CorporationInventor: Michael G.
