  • Patent number: 10408697
    Abstract: Techniques for improving implementation of a downhole tool string to be deployed in a borehole formed in a sub-surface formation. In some embodiments, a design device determines a model that describes expected relationship between properties of the downhole tool string, the borehole, the sub-surface formation, and mud cake expected to be formed in the borehole; determines calibration locations along the borehole based on properties of the borehole; determines candidate spacer configurations based on contact force expected to occur at contact points between the downhole tool string and the mud cake when deployed with each of the candidate spacer configuration via the model; and determines a final spacer configuration to be used to attach one or more spacers along the downhole tool string based on expected head tension to move the downhole tool string when deployed in the borehole with each of the candidate spacer configurations via the model.

  • Patent number: 9805440
    Abstract: In an embodiment, at least one computer readable storage medium has instructions stored thereon for causing a system to send, from a processor to a task execution device, a first call to execute a first subroutine of a set of chained subroutines. The first subroutine may have a first subroutine output argument that includes a first token to indicate that first output data from execution of the first subroutine is intermediate data of the set of chained subroutines. The instructions are also for causing the system, responsive to inclusion of the first token in the first subroutine output argument, to enable the processor to execute one or more operations while the task execution device executes the first subroutine. Other embodiments are described and claimed.

  • Publication number: 20160176014
    Abstract: Embodiments of the present invention provide systems, apparatus, and methods for an improved polishing head including an upper portion and a lower portion, the lower portion adapted to hold a substrate and to tilt relative to the upper portion, the tilt enabled by a spherical bearing, wherein the lower portion is adapted to tilt while rotating the substrate against a rotating polishing pad so that the lower portion remains flush against the rotating polishing pad while resisting lateral friction force generated by the rotating polishing pad contacting the substrate and pushing the substrate laterally against the lower portion. Numerous additional aspects are disclosed.

  • Patent number: 7671328
    Abstract: The present invention is devoted to an analytical method for directly determining carbon number and molecular weight distributions of isoparaffin mixtures. The analytical means uses low in-scan emitter-current field-ionization mass spectroscopy to substantially reduced or eliminated molecular ion fragmentation for isoparaffins, which allows direct measurement of isoparaffin molecular ions for their distributions. The analytical means is capable of directly characterizing isobutane to C50+ isoparaffins, covering naphtha to gas oil ranges.

  • Patent number: 6712478
    Abstract: A light emitting diode with strained layer superlatices (SLS) crystal structure is formed on a substrate. A nucleation layer and a buffer layer are sequentially formed on the substrate, so as to ease the crystal growth for the subsequent crystal growing process. An active layer is covered between an upper and a lower cladding layers. The active later include III-N group compound semiconductive material. A SLS contact layer is located on the upper cladding layer. A transparent electrode is located on the contact later to serve as an anode. Another electrode layer has contact with the buffer layer, and is separated from the lower and upper cladding layers.
