    Abstract: A system and method for measuring and controlling stator winding temperature in an AC motor while idling is disclosed. The system includes a circuit having an input connectable to an AC source and an output connectable to an input terminal of a multi-phase AC motor. The circuit further includes a plurality of switching devices to control current flow and terminal voltages in the multi-phase AC motor and a controller connected to the circuit. The controller is configured to activate the plurality of switching devices to create a DC signal in an output of the motor control device corresponding to an input to the multi-phase AC motor, determine or estimate a stator winding resistance of the multi-phase AC motor based on the DC signal, and estimate a stator temperature from the stator winding resistance. Temperature can then be controlled and regulated by DC injection into the stator windings.

    Abstract: Data in tables with foreign key relationship is synchronized in batches employing a two-pass process during playback based on whether the foreign key constraint is a linear dependency, self-referencing, or cyclic. A separate table containing a primary key of records and database timestamp columns for change operations may also be used for batch synchronization in addition to or instead of adding database timestamp columns to existing tables.

    Abstract: A tilted magnetic recording medium comprises a layer of magnetic material having a magnetic easy axis defined by tilted alignment of a particular crystalline phase of the magnetic material. A film of (101) and (011) textured L10 phase of a tetragonal crystalline magnetic material has crystalline c-axes oriented 45° to the medium surface normal. The L10 crystalline magnetic alloy comprises a first element selected from the group consisting of Co and Fe, and a second element selected from the group consisting of Pt and Pd. A seedlayer comprising a bcc or B2 crystal structure with a natural texture of (110) creates interfacial stress with the magnetic layer, giving rise to a pure (101) and (011) textured L10 crystalline film. A textured underlying surface facilitates preferential formation of the seedlayer and subsequent growth of the magnetic material to achieve tilted magnetic directions perpendicular to the recording tracks.
