A system and methods of performing searches within a universe of preexisting documents to extract a subset of relevant documents is disclosed. The user selects search terms or key words, and an application program performs a search of the universe of documents, compiles a subset or collection of documents based upon the search terms or keywords selected, and presents the resulting collection of documents to the user. An abstract marker such as a color highlighter, e.g. a color overlayed upon the key words such that the key word is visible through the colored portion, is associated with the keywords or criterion within a document. A collection of documents is presented as a group of second abstract markers, such as a pie chart, with colored segments representing keywords such that the proportion of instances of a keyword corresponds to the relative size of a segment within the pie chart.

A charged particle optical system comprising a beamlet generator for generating a plurality of beamlets of charged particles and an electrostatic deflector for deflecting the beamlets. The electrostatic deflector comprises first and second electrodes adapted for connection to a voltage for generating an electric field between the electrodes for deflection of the beamlets, the electrodes being at least partially freestanding in an active area of the electrostatic deflector. The electrodes define at least one passing window for passage of at least a portion of the beamlets between the electrodes, the passing window having a length in a first direction and a width in a transverse direction. The system is adapted to arrange the beamlets in at least one row and to direct a single row of the beamlets through the passing window of the electrostatic deflector, the beamlets of the row extending in the first direction. A substantial part of the electrostatic deflector extends beyond the passing window in the first direction.

An extra-oral digital panoramic dental x-ray imaging system is disclosed for multi-layer panoramic and transverse X-ray imaging. The system includes an X-ray source and a digital imaging device capable of “real time” frame mode output. The source and imaging device are mounted in a mechanical manipulator defining the trajectory of a predetermined image layer. The imaging device communicates with a processor that generates a frames memory from which an image reconstruction mechanism composes the final images. For “real time” imaging, the frames memory is a fast data storage system such as RAM. The processing unit executes the reconstruction algorithms, allowing the system to selectively generate dental panoramic X-ray images, dental transverse x-ray images and dental tomosynthetic 3D images.

Predetermined voltage is applied to a liquid crystal lens by a liquid crystal lens driver. Image signals are generated based on an optical image passed through the liquid crystal lens during transient response operation caused by application of the predetermined voltage, and plural focus signals are extracted by sampling the image signals of the area from which the focus signals are extracted at predetermined cycles. Levels of the extracted focus signals are compared to determine the maximum value of the focus signal. Thus, with the liquid crystal lens, by making use of the transient response operation of the liquid crystal lens, a focus point can be detected in sufficient speed.

A one-transistor (1T) NVRAM cell that utilizes silicon carbide (SiC) to provide both isolation of non equilibrium charge, and fast and non destructive charging / discharging. To enable sensing of controlled resistance (and many memory levels) rather than capacitance, the cell incorporates a memory transistor that can be implemented in either silicon or Sic. The 1T cell has diode isolation to enable implementation of the architectures used in the present flash memories, and in particular the NOR and the NAND arrays. The 1T cell with diode isolation is not limited to SiC diodes. The fabrication method includes the step of forming a nitrided silicon oxide gate on the Sic substrate and subsequently carrying out the ion implantation and then finishing the formation of a self aligned MOSFET.

A dissolvable jet vane (22 / 30) is a composite structure, having a support frame (38), a plug leading edge (40) connected to the forward edge (42) of the frame (38), and an insulation layer (44) on the side walls of the support frame (38). The dissolvable jet vane materials withstand the pressure and thermal loads associated with missile steering during the first few seconds of rocket boost until the missile attains sufficient speed to use conventional external aerodynamic control fins for steering control. Once control passes to the external fins, the jet vanes rapidly and uniformly dissolve in the exhaust stream. The dissolvable jet vane provides a lightweight, reliable means of removing steering jet vanes from the exhaust stream of a solid rocket motor nozzle.

A clutch assembly is provided for use in a vehicle having an automatic transmission, the assembly including a clutch-apply piston and an integrated one-way clutch, dog clutch apply plate, and synchronizer clutch having a synchronizer plate and a rotating synchronizer cone. The clutch assembly is actuated by a clutch-apply piston configured to axially displace the dog clutch apply plate, thereby engaging the synchronizer plate with the rotating synchronizer cone to synchronize the respective speeds of the synchronizer plate and dog clutch apply plate during a gear shifting event. Upon speed synchronization, continued axial displacement of the clutch-apply piston completes engagement of the dog clutch apply plate to achieve a coast gear state. A return spring provides a return spring force for disengaging the clutch apply piston to permit selection of an alternate gear state during a subsequent gear shifting event.
