Abstract: A biscuit inverter mechanism comprising a pair of elongate, parallel, downwardly angled support members. The spaced parallel support members provide support for a biscuit when running thereover to enable that biscuit to be guided with a constant orientation through the mechanism. The support members also provide support for one side only of a biscuit when running thereover whereby the biscuit rotates under gravity to an inverted orientation before leaving the mechanism.

Abstract: A key establishment protocol between a pair of correspondents includes the generation by each correspondent of respective signatures. The signatures are derived from information that is private to the correspondent and information that is public. After exchange of signatures, the integrity of exchange messages can be verified by extracting the public information contained in the signature and comparing it with information used to generate the signature. A common session key may then be generated from the public and private information of respective ones of the correspondents.

Abstract: A versioned-data management system (VDMSMS) is provided with a method for determining candidates for promotion in association with a user task. The VDMS maintains a list of parts changed as a result of a user task, referred to as a promote group. Before performing any changes the user informs the VDMS which user task is to be associated with the changes. All parts subsequently changed are automatically placed by the VDMS in the promote group associated with the given user task. When the parts associated with a user task for a given variant level are promoted, an iterative process is performed to determine the complete set of parts that must be promoted in support of the requested promote. Initially the set includes those parts in the promote group at the given variant level. Then all the other promote groups are searched to determine whether they contain any of the parts at the given variant level that are already in this set.

Abstract: The present invention is related to the method to find the rotor flux angle from stator voltages and currents by injecting high frequency signal. The injected signal is not rotating one but fluctuating one at a reference frame rotating synchronously to the fundamental stator frequency. The difference of impedances between the flux axis and the quadrature axis at high frequency signal injected on the rotor flux angle is explained by the equivalent circuit equation of the induction machine. The difference is verified by experiments on the test motors at various conditions. The sensorless field orientation control method is proposed and experimental results clarify the satisfactory operation of the method with 150% load torque at zero stator frequency.
Abstract: The invention concerns a drive assembly for relative movement of two components of a machine tool with a drive motor and a gear arrangement with two gear trains that can be put under tension relative to each other and have output gears that mesh with opposing teeth, where each gear train has a compact gear with a high transmission ratio with at least one control element for applying tension to the two gear trains. A high positioning accuracy and torsional rigidity combined with a small size when installed are made possible according to this invention by the fact that the compact gear.
Abstract: Micro-conduit with enhanced wetting characteristics for use in providing a blood heat exchanger apparatus with improved heat exchange capability. The micro-conduit comprises a plurality of elongated fibers, which may be made of a hydrophobic material such as polypropylene or polyethylene. Each fiber is open at two opposing ends, and has an inner surface between the open ends. The inner surface is coated with a wetting agent, such as phosphatidyl choline or another ampiphilic material with a hydrophilic end and a hydrophobic end. The fibers may have a shape and size that without presence of the wetting agent, would otherwise substantially impair free passage of water. The micro-conduit may be provided as a heat exchanger micro-conduit wrapping material, wherein micro-conduit fibers are attached to a thin flexible interconnect, such as woven netting, to maintain the fibers at predetermined spacings in substantially parallel alignment with each other.

Abstract: Compile and/or run time instruction scheduling is used in a multiprocessing system to reorder memory access instructions such that a strongly consistent programming model is emulated in a fashion transparent to the programmer. The multiprocessing system detects potential shared memory conflicts, avoiding these conflicts by restarting operation of the affected processing unit at a predetermined previous state, previously archived in a rollback register set, and resuming instruction execution from that state.

Abstract: A method and apparatus for measuring resistance of a blood sample in order to determine the hematocrit of that blood sample. The present invention makes a direct ratiometric measurement. That is, the alternating current that flows through the sample is directly measured by applying that alternating current to an integrator which converts the current to a D.C. voltage which is directly proportional to the applied current.
