    Abstract: A system and method for detecting cavitation in pumps for fixed and variable supply frequency applications is disclosed. The system includes a controller having a processor programmed to repeatedly receive real-time operating current data from a motor driving a pump, generate a current frequency spectrum from the current data, and analyze current data within a pair of signature frequency bands of the current frequency spectrum. The processor is further programmed to repeatedly determine fault signatures as a function of the current data within the pair of signature frequency bands, repeatedly determine fault indices based on the fault signatures and a dynamic reference signature, compare the fault indices to a reference index, and identify a cavitation condition in a pump based on a comparison between the reference index and a current fault index.

    Abstract: A dual-gate normally-off nitride transistor that includes a first gate structure formed between a source electrode and a drain electrode for controlling a normally-off channel region of the dual-gate normally-off nitride transistor. A second gate structure is formed between the first gate structure and the drain electrode for modulating a normally-on channel region underneath the second gate structure. The magnitude of the threshold voltage of the second gate structure is smaller than the drain breakdown of the first gate structure for proper operation of the dual-gate normally-off nitride transistor.

    Abstract: In a user interface apparatus, when a selected position of a to-be-processed image displayed on a display screen is detected through an area detecting unit, a menu display unit displays, in response to the detection of the selected position on the to-be-processed image, a link to at least one setting item being displayed in response to the selected position, the at least one setting item corresponding to a setting available for a setting area which corresponds to the selected position, where an order of display priority of the at least one setting item is determined by a size of the setting area. A determining unit determines that the setting item is specified, and an accepting unit accepts the setting corresponding to the setting item for the to-be-processed image. A preview display unit displays a preview indicating a result of processing the to-be-processed image based on the setting item.

    Abstract: An apparatus includes a plurality of bilayer structures positioned adjacent to each other, each of the bilayer structures including a first layer of magnetic material having a first Curie temperature and a second layer of magnetic material positioned adjacent to the first layer, wherein the second layer has a second Curie temperature that is lower than the first Curie temperature, and magnetic grains of the first layer are unstable when the second layer of magnetic material is heated above the second Curie temperature. The recording temperature is reduced due to the smaller switching volume achieved by using vertically decoupled laminations at elevated temperatures.

    Abstract: Aspects include recording media with enhanced areal density through reduction of head media spacing, head keeper spacing, or head to soft underlayer spacing. Such aspects comprise replacing currently non-magnetic components of devices, such as interlayers and overcoats with components and compositions comprising magnetic materials. Other aspects relate to magnetic seed layers deposited within a recording medium. Preferably, these aspects, embodied as methods, systems and/or components thereof reduce effective magnetic spacing without sacrificing physical spacing.
