Abstract: A 4/6 pole PSC motor having main and auxiliary winding configurations. Common windings are energized in both a 4-pole configuration and energized in a 6-pole configuration for both the main and the auxiliary winding configurations. An additional winding is energized in the 4-pole configuration only. As a result, the air-gap flux level of the 4-pole configuration can be varied substantially independent of the air-gap flux level of the 6-pole configuration by varying the configuration of the additional winding.

Abstract: An apparatus and method for producing composite data by a server computer with a distributed communication controller interface involves deforming a template creating a mapping relationship between co-registered data and subject data, filtering the co-registered data, and mapping this filtered co-registered data according to the mapping data. A client computer with a distributed communication controller interface requests the composite data from the server computer and transmits the subject data to the server computer. The client presents the received composite data to an operator and monitors the operators use of the composite data.

Abstract: A truss jigging system has tools moveable in a channel to different locations on an assembly table and which can be readily interchanged. The tools are capable of snap locking engagement with a carriage mounted in the table channels. A resilient component support on the carriage supports components of the truss in a position above the top of the assembly table. The component support deforms when a downward force is applied by a press for driving connector plates into the components so that the component engages the table. A heel locating device of the jigging system can be secured to the table and extended or retracted as needed to precisely locate the truss heel.

Abstract: An interactive environment is provided for integrated circuit (IC) designers to do an emulation session on a hardware accelerator 111 and then move to simulator 131, and vice versa. An aspect of the present inventive solution swaps memory state and logic storage node state (such as flip-flops and latches) between the accelerator 111 and simulator 131. A complete context switch is performed to create a time shared environment on hardware accelerator 111 so that multiple IC designers can access and use the accelerator. Multiple memory pages can be incorporated to minimize state swap time. Multiple accelerators 111 can be interconnected with a plurality of simulators 131 and a plurality of workstations 101 to allow multiple designers to do interactive operations and allows shifting back and forth between hardware emulation and software simulation.

Abstract: A system and method for detecting a registration mark representing a binary code sequence of N bits. A sensor is provided to output values indicating whether positive bits, negative bits, or no bits of the binary code sequence are detected. A sequence of N sensor values are provided to a code matching filter for comparison with the binary code sequence. The code matching filter increases a value of a detection signal for each sensor value which matches its corresponding bit, decreases the detection signal value for each sensor value which is complementary to its corresponding bit, and neither increases nor decreases the detection signal value in response to a sensor value indicating detection of no bit of the binary code sequence. When the binary code sequence is a Barker code, the code matching filter yields the ideal Barker auto-correlation function response whenever the binary code sequence is detected.

Abstract: A light weight surveying pole which is of robust and highly accurate construction. A lock for fixing telescoping sections of the pole provides fixed positioning without high initial clamping forces. An air cushion system inhibits damaging the pole sections when they are retracted, but the pole sections can be simply pulled apart without any other required disassembly for cleaning or repair. Fittings for use in screw-together pole sections are constructed to permit location within mating pole sections prior to application of adhesive for greater precision and maintenance of coincident axes of the pole sections when screwed together. Also, the end faces of the fittings are particularly formed to facilitate complete face-to-face contact and avoid misalignment when the fittings are attached. A cover can be attached over a point of the surveying pole when the point it not needed, and the cover can be stowed on the surveying pole when the point is used.
