20140199858 | THERMAL PROCESSING BY TRANSMISSION OF MID INFRA-RED LASER LIGHT THROUGH SEMICONDUCTOR SUBSTRATE - Thermal processing is performed by transmission of mid infra-red laser light through a substrate such as a semiconductor substrate with a limited mid infra-red transmission range. The laser light is generated by a rare-earth-doped fiber laser and is directed through the substrate such that the transmitted power is capable of altering a target material at a back side region of the substrate, for example, on or spaced from the substrate. The substrate may be sufficiently transparent to allow the transmitted mid infra-red laser light to alter the target material without altering the material of the substrate. In one example, the rare-earth-doped fiber laser is a high average power thulium fiber laser operating in a continuous wave (CW) mode and in a 2 μm spectral region. | 07-17-2014 |

20140157798 | Cryogenic Storage Container, Storage Device, and Methods of Using the Same - A device for the cryopreservation and/or vitrification of a biological sample in a freezing medium is described. The device preferably comprises a bath for receiving a vessel containing a biological sample in liquid-phase nitrogen. In one example, the bath includes a first member extending generally vertically from a bottom wall portion which divides the interior chamber of the bath into a first sub-chamber adapted for receiving a volume of cryogenic freezing medium and a second or overflow sub-chamber adapted to receive freezing medium from the first sub-chamber. A second member extends generally horizontally between the sidewall portions of the bath and includes at least one opening for receiving a biological sample-containing vessel(s). A kit including a cryogenic storage device and a vessel is also described. | 06-12-2014 |

20120294389 | CLOCK RECOVERY APPARATUS AND METHOD THEREOF - A method of recovering a clock signal from a digital signal in a receiver includes generating a representation of an eye diagram from symbols of the digital signal, in which the symbols are sampled at a sample rate such that the representation of the eye diagram is generated by a plurality of samples. The generated representation is converted into an array of data elements having a first set of data corresponding to the plurality of samples, and a second set of data representing a plurality of data bins. A plurality of measurements are performed on the array of data elements and/or the eye diagram to obtain a plurality of measurement outputs corresponding to the plurality of samples, which are combined at each sample. A sample is selected as a clock sample based on results of the combination. | 11-22-2012 |

20080262726 | METHOD AND GENERATOR FOR GENERATING A SPREAD-SPECTRUM SIGNAL - A method of generating a spread-spectrum signal in a navigation system comprises the steps of providing a carrier wave and a modulation waveform and modulating the carrier wave with the modulation waveform. The modulation waveform comprises a so-called anti-phase linear combination of a BOC(1,1) waveform and a BOC(m,1) waveform, expressible as α·BOC(1,1)−β·BOC(m,1), where m represents an even integer number, α and β are non-zero coefficients of the same sign, indicating the relative power split between the BOC(1,1) waveform and the BOC(m,1) waveform. | 10-23-2008 |

20140083765 | AUTOMATIC CONTROL SYSTEM AND METHOD FOR A DRILLING TOOL CHANGER APPARATUS - A control system for an automatic drilling tool changer apparatus for use with a drilling rig includes a drilling control device programmed with a control scheme for controlling the automatic drilling tool changer apparatus, and a user interface coupled to the drilling control device for initiating actions of the automatic drilling tool changer apparatus and for interactively monitoring a status of the automatic drilling tool changer apparatus. The control scheme includes steps for an automatic drilling tool change-out operation, and the drilling control device and the user interface are configured to communicate with the automatic drilling tool changer apparatus over a network. | 03-27-2014 |
20140083774 | DRILLING TOOL CHANGER APPARATUS - A drilling tool changer apparatus for a drilling rig includes a drill tower pivotable between a drilling orientation and a change-out orientation, the drill tower supporting a drill string comprising a drill pipe coupled to a drilling tool. The drilling tool changer apparatus also includes a drilling tool storage device pivotally movable about a hinge axis between a stowed position and a deployed position. The drilling tool storage device includes a drilling tool storage cassette including a replacement drilling tool. The drilling tool storage device and the drill tower are pivotally alignable in a substantially co-planar manner when the drilling tool storage device is in the deployed position and the drill tower is in the change-out orientation. | 03-27-2014 |
20140338973 | AUTOMATIC DRILL PIPE ADD AND REMOVE SYSTEM - A drilling rig carousel assembly includes a drilling rig carousel comprising a plurality of slots for holding drill components, a first actuator coupled to the drilling rig carousel and configured to axially rotate the drilling rig carousel, a second actuator coupled to the drilling rig carousel and configured to move the drilling rig carousel between a first position and a second position, and a sensor assembly. The sensor assembly includes a rotation sensor configured to monitor an axial rotation of the drilling rig carousel, and a position sensor configured to provide a signal representative of whether the drilling rig carousel is in the first position or the second position. | 11-20-2014 |

20140238795 | DAMPER UNIT - A damper unit includes first and second chambers, a first piston dividing the first chamber into first and second volumes, and a second piston dividing the second chamber into third and fourth volumes. Each piston is moveable along the respective chamber. The second chamber has a cross-sectional area that is smaller than the cross-sectional area of the first chamber so that the second chamber at least partially slides inside the first chamber and at least part of the first chamber can be located around the outside of the second chamber. The first piston is attached to the part of the second chamber that slides inside the first chamber. The position of the second piston is fixed relative to the first chamber as the second chamber slides relative to first chamber. The length of the damper unit changes as the second chamber slides relative to the first chamber. | 08-28-2014 |
