Abstract: A pump includes an electric motor with a rotor rotatably supported about an axis of rotation and circumferentially surrounding a stator. The stator includes a stator core and coils wound on the stator core. The windings are defined by a winding wire including winding wire end sections that are electrically contacted with a printed circuit board by a crimp connection.

Abstract: An apparatus and method is provided for simulating a physical computer system using virtualization. The disclosed system virtualizes devices of a physical computer system by modeling hardware and software components that are physically present within the physical computer system. The system simulates changing at least one of a piece of hardware or software in the virtualized computer system and assesses an effect of the change in the virtualized computer system to determine a potential effect of the change if the change were implemented on the physical computer system.

Abstract: A monitoring system for use with a horizontal directional drilling machine and adapted to determine the roll and/or pitch orientation of the downhole tool assembly by detecting signals from a sensor assembly supported by the downhole tool assembly. In a preferred embodiment, the monitoring system uses an antenna assembly to detect a signal transmitted from the sensor assembly. The antenna assembly transmits the detected signal to a processor which determines a calibration factor indicative of the actual orientation of the sensor relative to the known orientation of the downhole tool assembly. The processor then uses the calibration factor and the signal emitted from the sensor, indicative of the actual orientation of the sensor, to determine the actual orientation of the downhole tool assembly.
