Patent number: 8345526Abstract: Techniques are provided for increasing storage capacity in a holographic storage system. While typical holographic storage systems involve binary storage for each data position in a holographic disk, present techniques involve storing data such that more than two data levels may be recorded in each data position. In some embodiments, a recording beam directed to the disk may be adjusted to different power levels depending on the data level to be recorded. Furthermore, the recording time at a data position may be adjusted to increase the energy directed to the data position by increasing the amount of time the recording beam is impinged on the data position. Embodiments are suitable for different types of holographic storage, including dye-based medium.Type: GrantFiled: December 29, 2010Date of Patent: January 1, 2013Assignee: General Electric CompanyInventors: John Erik Hershey, Kenneth Brakeley Welles, John Anderson Fergus Ross, Xiaolei Shi, Zhiyuan Ren, Victor Petrovich Ostroverkhov

Publication number: 20120307617Abstract: Techniques are provided for increasing spectral efficiency over data channels in a storage or communication system. In some embodiments, data may be encoded and transmitted over multiple channels. The transmitted data from the multiple channels may be considered together as a channel bundle, thereby increasing the edge transitions of the group of signals to improve clock recovery and reduce coding constraints. In some embodiments, the channel bit size is reduced to maximize data rates based on the reduced coding constraints. Furthermore, the channel bundle has only one channel with timing markers, so that a receiver may receive information from the channel bundle and recover clocking based on the timing markers in the one channel.Type: ApplicationFiled: June 6, 2011Publication date: December 6, 2012Applicant: GENERAL ELECTRIC COMPANYInventors: John Anderson Fergus Ross, Michael James Hartman, John Erik Hershey, Richard Louis Zinser, Xiaolei Shi

Patent number: 8315139Abstract: Methods and systems are provided for recording micro-holograms in a holographic disk. Disk tilting or disk imperfections may cause counter-propagating recording and reference beams to deviate from the target data position in the disk. In some embodiments, a tracking beam is directed to a tracking position in the disk, and deviation of the tracking beam from the tracking position may indicate tracking and/or focusing errors of the recording and/or reference beams. A detector may generate an error signal in response to such errors. A first servo-mechanical system may actuate a first optical head (e.g., transmitting the reference and tracking beams) to compensate for such errors, and a second servo-mechanical system may actuate a second optical head (e.g., transmitting the recording beam) to follow the actuation of the first servo system, such that an interference of the reference beam and the recording beam may be maintained in the target data position.Type: GrantFiled: December 29, 2010Date of Patent: November 20, 2012Assignee: General Electric CompanyInventors: Zhiyuan Ren, Xiaolei Shi, Victor Petrovich Ostroverkhov, Xuefeng Wang

Patent number: 8273249Abstract: A new method that integrates electrochemical oxidation and flocculation processes for removing ammonia nitrogen in coking wastewater is disclosed in this invention. It comprises steps as follow: first, adjusting the PH of coking wastewater and adding Fe2+ into the wastewater; then leading the wastewater containing Fe2+ through such 5 areas as pulsed high-voltage discharge oxidation area, pulsed high-frequency DC electrolytic oxidation area, microbubble oxidation area, flocculation area and precipitation area in succession. High-voltage pulse and high-frequency pulse are two different mechanisms for achieving strong oxidation. With help of both solid and liquid catalysts, these two oxidations can work synergistically. The recalcitrant organic chemicals are effectively destroyed and satisfactorily removed out of wastewater. The high-concentration coking waster pretreated with this method will meet Chinese highest discharge standard as long as the routine biochemical treatment is applied thereafter.Type: GrantFiled: July 25, 2008Date of Patent: September 25, 2012Assignee: Nanjing UniversityInventors: Hongqiang Ren, Yunjun Yang, Lili Ding, Xiaolei Shi

Patent number: 8254224Abstract: Techniques are provided for controlling the reading of optical data from a master disk in a holographic replication system. Imperfections in the master disk or movement of the disk during a recording process may cause source beams to deviate from target data tracks. In some embodiments, a detector system is used to determine the focus and alignment of the source beams on the master disk, as well as the tilt and rotation of the disk with respect to the holographic replication system. The detector system may detect deviations in the intensity distribution of the reflections of the source beams and generate an error signal corresponding to focusing, tracking, tilt, and/or rotational errors. Servo-mechanical devices may actuate optical components to compensate for such errors.Type: GrantFiled: November 18, 2010Date of Patent: August 28, 2012Assignee: General Electric CompanyInventors: Xeufeng Wang, Pierino Gianni Bonanni, Xiaolei Shi, Zhiyuan Ren, Hua Xia, Victor Petrovich Ostroverkhov, Xinghua Wang

Patent number: 8248905Abstract: The present techniques provide techniques for outputting counter-propagating parallel light waves to pre-record a holographic data disk. The parallel light waves are transmitted through a holographic system via a fiber optic bundle including a plurality of polarization-maintaining (PM) optical fibers. Each of the PM optical fibers in the fiber optic bundle may have one or more of a different wavelength, a different coherence length, and a different polarization orientation to reduce crosstalk in the disk. Furthermore, the fiber optic bundle array is rotated to produce interference spots indicative of micro-holograms according to the data track pitch of the holographic disk over which the fiber optic bundle is outputting the light waves.Type: GrantFiled: October 15, 2010Date of Patent: August 21, 2012Assignee: General Electric CompanyInventors: Xinghua Wang, Xiaolei Shi, Hua Xia, Victor Petrovich Ostroverkhov

Patent number: 8238217Abstract: The present techniques provide methods and systems for enhancing a data signal in reading optical discs, such as holographic data discs. The techniques involve adjusting the position of a detector, or multi-pixel detector, such that the reflection corresponding to a micro-hologram or micro-reflector is enhanced. For example, the detector position may be adjusted to a position where the surface reflection and the micro-hologram reflection constructively interfere, resulting in an amplified micro-hologram reflection signal. Other parameters such as disc reflectivity and detector pinhole size may be adjusted to increase signal enhancement. Furthermore, the detector position may be adjusted to a position where the phases of the surface reflection and the micro-hologram reflection result in a weaker cross term.Type: GrantFiled: December 16, 2008Date of Patent: August 7, 2012Assignee: General Electric CompanyInventors: John Anderson Fergus Ross, Xiaolei Shi

Patent number: 8233368Abstract: The present techniques provide methods and systems for more reliable reading of optical data disks. In embodiments, a multi-pixel detector that is segmented into multiple areas, or detector segments, may be used to detect a pattern in the light reflected from an optical data disk. The pattern may include light scattered from a single bit that may be under a center detector, as well as light scattered from proximate bits. The detector system may then combine the quantized values from each of the detector segments mathematically to determine the presence or absence of a bit or bits of data. The mathematical combination may also use data that is known about the status of adjacent data bits (such as previously read bits, or bit patterns which are allowed or not allowed by specific data encoding schemes) to improve the accuracy of the bit prediction.Type: GrantFiled: December 18, 2008Date of Patent: July 31, 2012Assignee: General Electric CopanyInventors: John Anderson Fergus Ross, Kenneth Brakeley Welles, John Erik Hershey, Xiaolei Shi, Victor Petrovich Ostroverkhov
