20090107308 | METHODS AND SYSTEMS FOR CHIP BREAKING IN TURNING APPLICATIONS USING CNC TOOLPATHS - The present invention provides methods and systems for chip breaking, controlling cutting tool wear, and the like in turning, boring, and other applications, including: engaging a workpiece with a cutting tool in a feed direction along a toolpath, superimposing an oscillation in the feed direction on the toolpath, and dynamically or non-dynamically varying the oscillation superimposed in the feed direction on the toolpath such that interrupted cuts and chips of a predetermined length or less are produced. These systems take full advantage of computer numerical control (CNC) methodologies. | 04-30-2009 |
20110254495 | Method and Apparatus for Characterizing and Enhancing the Dynamic Performance of Machine Tools - Disclosed are various systems and methods for assessing and improving the capability of a machine tool. The disclosure applies to machine tools having at least one slide configured to move along a motion axis. Various patterns of dynamic excitation commands are employed to drive the one or more slides, typically involving repetitive short distance displacements. A quantification of a measurable merit of machine tool response to the one or more patterns of dynamic excitation commands is typically derived for the machine tool. Examples of measurable merits of machine tool performance include dynamic one axis positional accuracy of the machine tool, dynamic cross-axis stability of the machine tool, and dynamic multi-axis positional accuracy of the machine tool. | 10-20-2011 |
20110254496 | Method and Apparatus for Characterizing and Enhancing the Functional Performance of Machine Tools - Disclosed are various systems and methods for assessing and improving the capability of a machine tool. The disclosure applies to machine tools having at least one slide configured to move along a motion axis. Various patterns of dynamic excitation commands are employed to drive the one or more slides, typically involving repetitive short distance displacements. A quantification of a measurable merit of machine tool response to the one or more patterns of dynamic excitation commands is typically derived for the machine tool. Examples of measurable merits of machine tool performance include workpiece surface finish, and the ability to generate chips of the desired length. | 10-20-2011 |

20110066919 | MEMORY ERROR DETECTION AND/OR CORRECTION - An embodiment may include circuitry that may detect and/or correct at least one error in a data codeword that may include a data word, cyclical redundancy check (CRC) word, and parity word. The circuitry may select whether a portion of the CRC word indicates whether only a single processor has accessed the data word. The data word, CRC word, and the parity word may be accessible in respective distinct memory device sets that each may include one or more respective memory devices. If the circuitry detects, based at least in part upon the data codeword and CRC word, a CRC error, and the at least one error includes fewer than a first predetermined number of errors, the circuitry may determine in which of the one or more respective memory devices in the memory device sets the at least one error resides and may correct the at least one error. | 03-17-2011 |

20080253021 | Non-magnetic contact enhancement feature - A transducer having an external contact surface includes a writer and a contact member. The writer has a portion extendable beyond the external contact surface. The contact member surrounds at least a portion of the extendable writer portion. | 10-16-2008 |
20130000107 | Contact feature for use with transducing devices - A transducer having an external contact surface includes a writer and a contact member. The writer has a portion extendable relative to an adjacent portion of the external contact surface. The contact member surrounds at least a portion of the extendable writer portion and is spaced from the extendable writer portion. The coefficient of thermal expansion of the contact member is approximately equal to the coefficient of thermal expansion of the extendable writer portion. | 01-03-2013 |
20140113160 | ARTICLES INCLUDING INTERMEDIATE LAYER AND METHODS OF FORMING - Articles that include a magnetic structure; an intermediate layer, the intermediate layer positioned on the magnetic structure, the intermediate layer having a thickness from about 3 Å to about 50 Å, the intermediate layer including a bottom interface layer, the bottom interface layer positioned adjacent the magnetic structure, the bottom interface layer including atoms of a metal bonded to atoms, compounds, or both of the magnetic structure; an interlayer, the interlayer positioned on the bottom interface layer, the interlayer including oxides of the metal; and a top interface layer, the top interface layer positioned adjacent the interlayer, the top interface layer including atoms of the metal, oxides of the metal, or some combination thereof bonded to atoms or compounds of the adjacent overcoat layer; and an overcoat layer, the overcoat layer positioned on the top interface layer of the intermediate layer. | 04-24-2014 |
20150055441 | MAGNETIC DEVICE INCLUDING A NEAR FIELD TRANSDUCER - A recording device and a method of forming a recording device are disclosed.
