20150202269 | AAV-MEDIATED GENE THERAPY FOR RPGR X-LINKED RETINAL DEGENERATION - Described herein are methods of preventing, arresting progression of or ameliorating vision loss and other conditions associated with retinitis pigmentosa and x-linked retinitis pigmentosa in a subject. The methods include administering to said subject an effective concentration of a composition comprising a recombinant adeno-associated virus (AAV) carrying a nucleic acid sequence encoding a normal retinitis pigmentosa GTPase regulator (RPGR gene), or fragment thereof, under the control of regulatory sequences which express the product of the gene in the photoreceptor cells of the subject, and a pharmaceutically acceptable carrier. | 07-23-2015 |

20090128378 | MODULATION CODING - Methods and apparatus are provided for modulation coding of input data. In a first scheme, a modulation encoder applies a modulation code to input data to produce an (L,K)-constrained encoded bit-sequence, where K is maximum run-length of 0's, and L is the maximum run-length of 0's in each of the odd and even interleaves of the encoded bit-sequence. Then, a precoder effects 1/(1⊕D | 05-21-2009 |

20090174964 | SERVO CHANNEL FOR TAPE DRIVE SYSTEMS - Provided are techniques for synchronous servo channel for a data tape drive. A servo reader is configured to read servo bursts from a data tape. An anti-aliasing filter is operable to output a bandlimited signal and is coupled to receive a servo channel signal comprising servo bursts from the servo reader. An analog-to-digital converter (ADC) is operable to output signal samples and is coupled to receive the bandlimited signal from the anti-aliasing filter. An interpolation and control unit is operable to output interpolated signal samples and control signals, has a first input coupled to receive the signal samples from the ADC, and has a second input coupled to receive the correlation signal samples from the dibit correlator. A dibit correlator is operable to output correlation signal samples and is coupled to receive the interpolated signal samples and control signals from the interpolation and control unit. | 07-09-2009 |
20090237832 | ERROR CORRECTION CODING OF LONGITUDINAL POSITION INFORMATION - A sequential data storage medium, comprising a sequence of plurality of servo patterns that provide lateral position information and longitudinal position information, wherein each of the plurality of servo patterns comprises a first burst comprising a first plurality of pulses, a second burst comprising a second plurality of pulses, a third burst comprising a third plurality of pulses, and a fourth burst comprising a fourth plurality of pulses. The spacings between the first plurality of pulses, in combination with the spacings between the second plurality of pulses, encode a first bit without affecting the recovery of lateral position information. The spacings between the third plurality of pulses, in combination with the spacings between the fourth plurality of pulses, encode a second bit without affecting the recovery of lateral position information. The sequence of plurality of servo patterns comprises a sequence of the first bits and a sequence of the second bits to form an error-correction codeword providing error-correction capability. | 09-24-2009 |
20100232047 | DATA INTERLEAVING IN TAPE DRIVES - Methods and apparatus for interleaving data in a multitrack tape drive and for writing data on a multitrack tape in the tape drive. One method includes: partitioning the data into m(2 | 09-16-2010 |

20090316773 | WORD SYNCHRONIZATION FOR SERVO READ SIGNALS IN TAPE DRIVES - Methods and apparatus for detecting L-bit sync words occurring at N-bit intervals in PPM-encoded servo pattern read signals read in magnetic tape drives. A soft output detector processes the PPM-encoded servo pattern read signal to produce a series of soft output samples corresponding to respective bits encoded in the servo pattern. A sync word detector then produces block correlation values for respective positions of a sliding L-sample block in the series of soft output samples by (i) calculating at each block position bit correlation values indicating correlation between respective samples and corresponding bits of the sync word and (ii) summing each bit correlation value minus a predetermined function of the corresponding sample value. The sync word detector then detects a sync word at the block position with the maximum block correlation value in an (N+L−1)-sample sequence of the series of soft output samples. | 12-24-2009 |
