20110268390 | ACTIVE OPTICAL CABLE THAT IS SUITED FOR CONSUMER APPLICATIONS AND A METHOD - An active optical cable is provided that is well suited for consumer applications. In contrast to known Quad Small Form-Factor Pluggable (QSFP) active optical cables, the active optical cable incorporates at least one consumer input/output (CIO) optical transceiver module that is well suited for consumer applications. The plug housing of the known QSFP active optical cable has been modified to house at least one CIO optical transceiver module that utilizes laser diode and photodiode singlets, rather than the parallel laser diode and photodiode arrays used in the known QSFP active optical cables. These features reduce the overall cost of the active optical cable and make it well suited for consumer applications. | 11-03-2011 |
20110293221 | CONSUMER INPUT/OUTPUT (CIO) OPTICAL TRANSCEIVER MODULE FOR USE IN AN ACTIVE OPTICAL CABLE, AN ACTIVE OPTICAL CABLE THAT INCORPORATES THE CIO OPTICAL TRANSCEIVER MODULE, AND A METHOD - A consumer input/output (CIO) optical transceiver module, an active optical cable that incorporates a CIO optical transceiver module, and a method for using a CIO optical transceiver module in an active optical cable are provided. In contrast to optical transceiver modules currently used in active optical cables, which utilize parallel arrays of laser diodes and parallel arrays of photodiodes, the CIO optical transceiver module includes two singlet laser diodes and two singlet photodiodes for providing two high-speed transmit channels and two high-speed receive channels, respectively. Because the singlet laser diodes and photodiodes of the CIO optical transceiver module are less costly than the parallel arrays of laser diodes and parallel arrays of photodiodes that are used in known active optical cables, the CIO optical transceiver module can be manufactured at relatively low costs with high quality, and therefore is well suited for consumer applications. | 12-01-2011 |

20120251049 | OPTICAL TRANSCEIVER MODULE EQUIPPED WITH AN ELONGATED DELATCHING PULL TAB, AND A METHOD - An optical transceiver module is provided with an elongated delatching pull tab that that enables an optical transceiver module to be easily delatched and pulled from a cage without having to first unplug optical fiber cables from the module and without having to rotate a bail. Thus, the number of manual actions that need to be performed by a user to remove the module from a cage is drastically reduced, which makes simplifies the removal process and makes the design well suited for use in hot-pluggable environments. In addition, the delatching pull tab obviates the need for pins or screws, thereby improving manufacturing yield by reducing the likelihood that the module will be damaged during the manufacturing process. In addition, by eliminating pins or screws and a bail from the design, there are fewer moving parts that can wear out over time. | 10-04-2012 |

Furthermore, deformation of the deformable features also removes space between the optical subassembly and the module body caused by mechanical tolerance differences that occur during manufacturing. | 10-04-2012 |

20130129302 | FLEXIBLE DUST COVER FOR USE WITH A PARALLEL OPTICAL COMMUNICATIONS MODULE TO PREVENT AIRBORNE MATTER FROM ENTERING THE MODULE, AND A METHOD - A flexible dust cover is provided for use with a parallel optical communications module for preventing airborne matter, such as dirt, dust, and gases from entering the module. The flexible dust cover fits snugly to the module to protect components of the module and the optical pathways of the module from airborne matter. The flexible dust cover has an elasticity that allows it to be temporarily deformed from its original shape to a stretched state by application of a stretching force to enable the module to be inserted into a central opening formed in the cover. The force is then removed, causing the cover to attempt to return to its original, non-stretched shape. When this happens, interior surfaces of the cover form a snug fit about exterior surfaces of the module. This snug fit fills in air gaps in the module that would otherwise be exposed to the environment. | 05-23-2013 |

20110027407 | PROFILE CONTROL UTILIZING A RECESSED IMPRINT TEMPLATE - An imprint template is provided with a shallower field bordering the patterned region. The shallower field can be formed with additional lithography/etch steps after (or before) the formation of the features in the patterned region. The template is used to establish a thin film pattern with a field thickness that is shallower than the pattern. A shallower field bordering the patterned region alleviates sidewall re-deposition during ion mill. In a planarization/etch-back process, a thinner field helps to achieve a flat top surface by compensating for the thickness variation caused by different filling ratios. Fabrication of the recessed field template comprises a multi-step patterning process. The initial patterns are formed using a convention fabrication process. A second patterning step is used to reduce the height of the field region, which can be applied by coating the “half-finished” template with a suitable resist pattern and patterning the resist using a second lithography step that is aligned to the original pattern. Template material in the field region is then etched with the resist as a mask, forming a template with a recessed field region after the remaining resist is removed. It should be appreciated that the order of these etch steps can be reversed to obtain the same result. | 02-03-2011 |
20110128647 | METHOD OF DISK ALIGNMENT USING PRINTED ALIGNMENT MARKS - Processes include aligning a disc with a template at a location so that the pattern from the template is transferred to the disc in a relative orientation. The relative orientation provides that when the disc with the transferred pattern is finally assembled into a hard disc drive, an inner diameter of the spindle hole of the disc may be abutted against an outer diameter of the disc drive spindle, and the data-containing patterns on the discs will be aligned concentrically with a center of the disc drive spindle. While the data-containing patterns are aligned concentrically with the disc drive spindle, the substrate itself is allowed to be non-concentric. Still other aspects include a disc having eccentric formations including PIM and one or more of bit patterns and servo information formed on a disc surface, the eccentricity of the formations is determined based on an expected difference between the radius of the spindle hole of the disc and the radius of the spindle on which the disc will be placed during assembly, with the PIM used to determine the angular alignment of the disc with the spindle. | 06-02-2011 |
