摘要:
This invention relates in part to a processes for the conversion of a feedstock stream comprising carbon monoxide and hydrogen to a product stream comprising at least one of an ester, acid, acid anhydride and mixtures thereof. This invention also relates in part to processes for converting an alcohol and/or ether feedstock to oxygenated products, e.g., esters, acids, acid anhydrides and mixtures thereof. The processes and catalysts are especially suitable for the production of acetic acid and methyl acetate from a synthesis gas feedstock or from an alcohol and/or ether feedstock.

Loss-less data compression/decompression especially useful in a limited resource environment such as a handheld portable video game system allows graphics and/or attribute data to be efficiently and quickly decompressed on an as-needed basis in real time response to interactive user inputs. A two-level run-length-encoding is used to encode redundant patterns and redundant symbols. A common sentinel field format encodes whether data following the field is non-redundant data, a symbol run, or a pattern run. Compression ratios of 60% for representative symbol-mapped video display graphics/attribute files can be achieved.

A computational array includes a self timed computational element that performs self timed calculations internally independent of a global clock. The self timed computational element includes a computational unit (100) which produces a complete signal upon the completion of calculation of a result value. The self timed computational element also includes a self timed control unit (200) which determines whether a new result value is to be calculated by the computational unit (100) based on an iteration signal which indicates a number of times the new result value is to be calculated, and based on the complete signal received from the computational unit (100) indicating that each previous calculation has been completed. Upon determining that a new result value is to be calculated, the self timed control unit (200) provides a self timed clock signal to the computational unit (100) and the computational unit (100) calculates the new result value accordingly.
摘要:
A case for storing a collection of toy vehicles or models which simulates the appearance of the steering wheel of a vehicle. The case includes top and bottom members, each having a circular profile, which mate in a clamshell manner. The members are connected together by a hinge mechanism which is secured in a closed position by a latch. An opening extends through the top and bottom members to form a carrying handle.

This patent defines a method for making robot programming more intuitive for tasks such as welding. The method further is an enhancement of manual guiding methods of robot positioning and can improve situations in which finer resolution or control of the robot end-effector is required. A motion sensor is mounted in series with the n−1 joint and in parallel with the nth joint, where n is the number of degrees of freedom or number of joints of the serial manipulator. The motion sensor is further mounted directly in-line with the nth joint and becomes part the opposing portion of the nth joint. The motion sensor further is uniquely adapted to apply to non-spherical wrist robots. The motion sensor senses input movements by a robot operator and controls the output tool motion in a controlled manner with resolution defined by user input at the motion sensor.
摘要:
A climbing vehicle with wheel or endless-track type propulsion using suction for generating adhering forces is adapted to climbing non-planar surfaces such as intersecting walls, pipes or other structural members. The suction chamber is relatively fixed to the vehicle chassis and moves with the vehicle chassis. A seal is created around the suction chamber through an adaptive sealing mechanism. The adaptive sealing mechanism consists of a series of links that adapt to the climbing surface geometry and forms a seal at the climbing surface. The links in the adaptive sealing mechanism span a portion of the suction chamber along the longitudinal sides of the vehicle and are elastically sprung to maintain contact with the surface. The adaptive sealing mechanism links also span the lateral sides of the vehicle to fully enclose the suction chamber. Thus, the suction chamber is maintained even as the mobile vehicle passes over significant geometry changes in the climbing surface, for example transitioning between surfaces that are orthogonally opposed.

This disclosure relates to methods of reducing inflammation, angiogenesis, vascular leakage and neovascularization by administering to a subject in need thereof one or more stable analogs of CYP450 lipid metabolites (e.g., eicosanoids) and one or more inhibitors of a soluble epoxide hydrolase (sEH). This disclosure also relates to methods of treating disorders associated with inflammation, angiogenesis, vascular leakage and neovascularization by administering to a subject in need thereof one or more stable analogs of CYP450 lipid metabolites (e.g., eicosanoids) and one or more inhibitors of a soluble epoxide hydrolase (sEH). This disclosure further relates to pharmaceutical compositions and kits comprising at least one stable analog of CYP450 lipid metabolites (e.g., eicosanoids) and at least one inhibitor of a soluble epoxide hydrolase (sEH).
