| 20100157459 | Systems and Methods for Controlling Data Equalization - Various embodiments of the present invention provide systems and methods for performing data equalization. For example, various embodiments of the present invention provide data equalization circuits that include an equalization circuit and a transition adjustment circuit. The equalization circuit receives a series of at least two original data bits and replaces at least one of the two original data bits with an equalization pattern including two or more equalization bits. The original data bits correspond to an original data clock, and the two or more equalization bits correspond to an equalization data clock. The transition adjustment circuit is operable to modify an occurrence of a transition from one logic state to another logic state within the equalization pattern on a sub-equalization data clock basis. | 06-24-2010 |

For example, various embodiments of the present invention provide storage devices that include a semiconductor device having an equalization unit and a digital-to-analog converter, a read/write head assembly located in close proximity to the semiconductor device, and a control unit located less proximate to the read/write head assembly than the semiconductor device. | 06-24-2010 |
| 20100157768 | Systems and Methods for Generating Equalization Data Using Shift Register Architecture - Various embodiments of the present invention provide systems and methods for data equalization. For example, various embodiments of the present invention provide methods for generating equalization data. The method includes inputting N bits of an equalization data pattern into respective stages of a shift register, wherein inputting the N bits occurs synchronous to a system data clock having a system data rate, and shifting the N bits of equalization data to next adjacent next stages of the shift register synchronous to an equalization data clock having an equalization data rate N times the system data rate. | 06-24-2010 |

| 20110054467 | Cutting Assembly for Surgical Instruments - The present disclosure relates to an end effector assembly for use with a forceps. The end effector assembly includes a pair of jaw members and a cutting element. The pair of jaw members having at least one jaw member that is moveable relative to the other from a first, open position to a second, closed position for grasping tissue. Each of the jaw members includes a cutting channel that is defined therein and extends therealong. The cutting element includes a fixed end and a movable end. The fixed end is disposed within the cutting channel of one of the jaw members and the moveable end is disposed within the cutting channel of the other of the jaw member. The cutting element defines a movable cutting loop disposed between the cutting channels and between the fixed end and the movable end. The cutting loop has an arcuate portion that is reciprocatable to cut tissue. | 03-03-2011 |
| 20110105843 | Surgical Instrument With Tendon Preload-and-Locking Device - A surgical instrument includes a handle, an elongated shaft and an end effector extending distally from the shaft. A tensile member is preloaded with a tensile force and extends at least partially through the shaft. A preload mechanism for adjusting the tensile force includes first and second guides in contact with the tensile member to restrain the tensile member at respective first and second lateral distances from a longitudinal axis. A third guide is disposed longitudinally between the first and second guides and is in contact with the tensile member to restrain the tensile member at a third lateral distance from the longitudinal axis. The third guide is movable to vary the third lateral distance and a corresponding length of the tensile member disposed longitudinally between the first and second guides to thereby vary the tensile force. | 05-05-2011 |
| 20110106073 | Jaw Roll Joint - A surgical instrument includes a handle, and an elongated shaft extending from the handle. An end effector extending from the elongated shaft is in communication with a source of electrosurgical energy and defines an end effector axis. A roll joint couples the end effector to the elongated shaft and includes a first tubular structure extending distally from the elongated shaft and a second tubular structure rotatably coupled to the first tubular structure. The second tubular structure supports the end effector such that the end effector is rotatable about the end effector axis. A cable wrap volume may be disposed within one of the first and second tubular structures, and a conductor for supplying the end effector with electrosurgical energy is coiled about the end effector axis within the cable wrap volume such that rotation of the end effector about the end effector axis in a first direction unwinds the conductor. | 05-05-2011 |
| 20110106078 | Coaxial Drive - A surgical instrument includes a handle and an elongated shaft that defines a longitudinal axis. An end effector extends from the elongated shaft and defines an end effector axis. The elongated shaft includes an articulating portion that both pivotally and rotationally movable with respect to the longitudinal axis. The end effector is rotationally movable with respect to the end effector axis. A drive mechanism includes at least one actuator disposed on the handle that is operable to move the end effector in at least three independent modes relative to the longitudinal axis or the end effector axis. The three modes include an articulation mode wherein the articulating portion of the elongated shaft pivots relative to the longitudinal axis, a shoulder roll mode wherein the articulating portion of the elongated shaft rotates about the longitudinal axis, and a wrist roll mode wherein the end effector rotates about the end effector axis. | 05-05-2011 |
| 20110184405 | Compact Jaw Including Split Pivot Pin - An end effector assembly for use with a forceps includes a pair of jaw members, a knife assembly, and one or more cam assemblies. One or more of the jaw members are moveable relative to the other about a pivot between open and closed positions. One or more of the jaw members include a knife channel. The pivot includes first and second sections defining a passage therebetween. The knife assembly includes a knife blade and an actuation shaft. The knife blade is disposed distally relative to the pivot. The actuation shaft is configured for slidable translation through the passage to allow selective advancement of the knife blade through the knife channel. The one or more cam assemblies are operably coupled to the one or more moveable jaw members and are actuatable to move the one or more jaw members between the open and closed positions for grasping tissue therebetween. | 07-28-2011 |

| 20090243921 | SYNCHRONIZATION OF DATA ON SURVEY DEVICES - Tools for synchronizing survey data between one or more survey devices and a surveying office application. The disclosed tools can help to ensure that each of the devices, and the office application, have consistent data. An exemplary tool might detect a change to data in an office application, identify any affected files on one or more survey devices, and ensure that the affected files are updated with the appropriate information. Conversely, in other aspects, a data inconsistency (which might be caused by a data change in the office application and/or on one or more of the survey devices) might be detected, and tools might be provided to enable a user to ensure that the correct version of the data is maintained by the system. | 10-01-2009 |
