Abstract: Embodiments are provided that include a memory system that includes a memory system, having an access device coupled between a global line and a local line and a voltage source coupled to the global line and configured to output a bias voltage on the global line when the memory system is in a non-operation state. The access device is selected when the memory system is in the non-operation state, and the access device is deselected when the memory system is in an other state. Further embodiments provide, for example, a method that includes coupling a global access line to a local access line, biasing the local access line to a voltage other than a negative supply voltage while a memory device is in a first state and uncoupling the global access line from the local access line while the memory device is in an other state.
Abstract: A system and method are provided for controlling an internal combustion engine driving a generator/welder or a stand-alone generator. Controlling the engine may include altering the engine speed based upon a detected demand on the generator and/or operating parameters of a welder. For example, the engine speed may be increased based on a detected draw on the generator and/or the operating parameters of the welder. In addition, the engine speed may be automatically decreased to a non-standard idle speed or the engine may be automatically turned off if no demand is detected for a period of time. Additionally, the engine speed may be increased if only frequency-insensitive demands are detected on the generator. Combinations of these and further methods may be executed. Various devices are provided for implementing the above methods.

Abstract: A device is provided for riding through brownouts, or transitory losses of control power applied to electromagnetic devices such as contactors and relays. An energy storage circuit stores charge that can be discharged into a contactor operating coil during partial or full losses of control power and for short durations. Momentary reductions in control power can thus be experienced without opening or otherwise changing the logical state of the contactor. Emergency stop override circuitry may be provided for preventing the ride-through performance, thus enabling the device to provide for both ride-through of short losses of control power, while permitting emergency stopping of loads due to the override.
Abstract: The present techniques provide methods and systems for alignment of a read head with data tracks on an optical data disk. In embodiments, a multi-pixel detector that is segmented into multiple areas, or detector segments, may be used to detect a pattern in the light reflected from an optical data disk. The detector system may then combine the quantized values from each of the detector segments mathematically to determine the alignment of the read head with a target data track. If the read head drifts to one side or the other, detectors to the side of a center detector may start to pick up energy from the adjacent tracks. If this energy is continuously summed for the detectors on each side, the read head may be centered by balancing the sums from the detectors on each side.

Abstract: A technique for prioritizing portions of compressed multi-resolution medical image data to be processed. More relevant portions of medical image data are compressed at a higher resolution than less relevant portions of medical image data. A mask is created from the image data and used to assign data compression quality factors to corresponding image blocks in the image data. The image data in each region is compressed based on their assigned quality factor. During processing of the compressed image data, the compressed image data and the mask are accessed. The mask is used to direct the processing of the compressed image data. Depending upon the application, the mask can be used to direct that the image data for the regions of most relevance be processed before the image data for the regions of lesser relevance. However, the mask can be used to direct that the image data for the regions of lesser relevance be processed before the image data for the regions of most relevance.
