20110181227	Method of Determining the Position of the Drive Mechanism of an Electric Machine, Such as a Motor, from the Current Supplied, and Arrangement for Carrying Out the Method - A method and arrangement for determining the position of the drive mechanism of an electric machine from the current supplied thereto. Determination of the position is effected over two independent channels by measuring the three-phase current of the electric machine or motor, converting the measured values to the current space vector, calculating the angle of the current space vector within one electrical revolution, and determining the position of the motor. A current command, the field of which acts in the direction of the flux or field of the drive mechanism or rotor, is added within the motor stator.	07-28-2011
20130328516	METHOD AND POSITION DETECTION APPARATUS FOR DETECTING A POSITION OF A MOVABLE ELEMENT OF A DRIVE APPARATUS - A method for detecting a position of a movable element of a drive apparatus by means of a position detection apparatus comprising at least one field coil and at least one secondary coil associated with the field coil, wherein an electrical excitation pulse is applied to the field coil in order to induce an electrical voltage in the secondary coil, a secondary coil voltage is measured and the position of the movable element is determined on the basis of the measured secondary coil voltage. The invention also relates to a position detection apparatus and/or a drive apparatus.	12-12-2013

20110131167	LP relaxation modification and cut selection in a MIP solver - Mixed integer programs (MIP) are solved by constructing and solving associated linear programming (LP) relaxation problems. The LP relaxations are iteratively constructed through the introduction of cutting planes that are derived using one solution of an LP, then filtered based on an alternative solution to the LP. The LP relaxation is constructed, and its alternate solution is derived, to efficiently converge to a solution for the MIP.	06-02-2011
20120311604	DETERMINISTIC PARALLELIZATION THROUGH ATOMIC TASK COMPUTATION - A method for deterministic locking in a parallel computing environment is provided. The method includes creating a data structure in memory of a computer for a shared resource. The data structure encapsulates a reference to an owner of a lock for the shared resource and a queue of threads able to seek exclusive access to the shared resource. The queue in turn includes different entries, each entry including an identifier for a corresponding one of the threads and a deterministic time computed for the corresponding one of the threads from a count of memory accesses occurring in the corresponding one of the threads. Consequently, a thread can be selected from the queue to receive ownership of the lock and exclusive access to the shared resource based upon a deterministic time for the selected thread as compared to other deterministic times for others of the threads in the queue, for example, a lowest deterministic time.	12-06-2012
