20080211963 | Equipment For Audio-Video Processing System - The invention provides a processing system, comprising a video signal processing unit for processing a video signal, the video signal processing entailing a video signal processing delay, and video delay control for controlling said video signal processing unit in dependence on a maximum allowed value for the video signal processing delay. The invention also provides an audio-video signal source, comprising an output for sending a video signal to a video signal processing unit, and an output for communicating to the video signal processing unit a maximum allowed value for a video signal processing delay entailed by video signal processing in the video signal processing unit. The invention further provides an audio signal processing unit, comprising an audio signal processing unit, said audio signal processing entailing an audio signal processing delay not exceeding a maximum audio delay, and an output for communicating to the video signal processing unit a maximum allowed value for a video signal processing delay entailed by video signal processing in the video signal processing unit, the maximum allowed value for the video signal processing delay depending on the maximum audio delay. | 09-04-2008 |

20110292189 | 3D DISPLAY HANDLING OF SUBTITLES - A non-transitory three-dimensional image signal includes a first image component, a second component for creating a three-dimensional image in combination with the first image component, and a text component that includes text-based subtitles and/or presentation graphics-based bitmap images for including in the three-dimensional image. A shared Z-location component includes Z-location information describing the depth location of the text component within the three-dimensional image. The signal is rendered by rendering the three-dimensional image from the first image component and the second component. The rendering includes rendering the text-based subtitles and/or presentation graphics-based bitmap images in the three-dimensional image. Further, the rendering of the text component includes adjusting the depth location of the text-based subtitles and/or presentation graphics-based bitmap images based on the shared Z-location component. The Z-location for both text-based and presentation-graphics-based subtitles may be the same and only needs to be stored once per stream. | 12-01-2011 |

20130028059 | MAGNETIC RECORDING DISK DRIVE WITH SHINGLED WRITING AND RECTANGULAR OPTICAL WAVEGUIDE FOR WIDE-AREA THERMAL ASSISTANCE - A thermally-assisted recording (TAR) disk drive uses “shingled” recording and a rectangular waveguide as a “wide-area” heat source. The waveguide generates a generally elliptically-shaped optical spot that heats an area of the recording layer extending across multiple data tracks. The waveguide core has an aspect ratio (cross-track width to along-the track thickness) that achieves the desired size of the heated area while locating the peak optical intensity close to the trailing edge of the write pole tip where writing occurs. The large cross-track width of the waveguide core increases the volume of recording layer heated by the optical spot, which reduces the rate of cooling. This moves the peak temperature point of the heated area closer to the write pole tip and reduces the temperature drop between the peak temperature and the temperature at the trailing edge of the write pole tip where writing occurs. | 01-31-2013 |

20140291283 | METHOD FOR MAKING A CURRENT-PERPENDICULAR-TO-THE-PLANE (CPP) MAGNETORESISTIVE (MR) SENSOR WITH REDUCED-WIDTH SELF-ALIGNED TOP ELECTRODE - A method for making a current-perpendicular-to-the-plane magnetoresistive sensor structure produces a top electrode that is “self-aligned” on the top of the sensor and with a width less than the sensor trackwidth. A pair of walls of ion-milling resistant material are fabricated to a predetermined height above the biasing layers at the sensor side edges. A layer of electrode material is then deposited onto the top of the sensor between the two walls. The walls serve as a mask during angled ion milling to remove outer portions of the electrode layer. The height of the walls and the angle of ion milling determines the width of the resulting top electrode. This leaves the reduced-width top electrode located on the sensor. Because of the directional ion milling using walls that are aligned with the sensor side edges, the reduced-width top electrode is self-aligned in the center of the sensor. | 10-02-2014 |
20140340791 | CURRENT-PERPENDICULAR-TO-THE-PLANE (CPP) MAGNETORESISTIVE SENSOR WITH REDUCED-WIDTH TOP AND BOTTOM ELECTRODES AND METHOD FOR MAKING - A current-perpendicular-to-the plane magnetoresistive sensor has top and bottom electrodes narrower than the sensor trackwidth. The electrodes are formed of one of Cu, Au, Ag and AgSn, which have an ion milling etch rate much higher than the etch rates for the sensor's ferromagnetic materials. Ion milling is performed at a high angle relative to a line orthogonal to the plane of the electrode layers and the layers in the sensor stack. Because of the much higher etch rate of the material of the top and bottom electrode layers, the electrode layers will have side edges that are recessed from the side edges of the free layer. This reduces the surface areas for the top and bottom electrodes, which causes the sense current passing through the sensor's free layer to be confined in a narrower channel, which is equivalent to having a sensor with narrower physical trackwidth. | 11-20-2014 |
