Abstract: An instrumentation setup is provided to process electronic signals in a positron imager functioning in two different modes of operations for scanning both bulk and thin film materials. According to one part of an implementation, an instrumentation setup comprises an XY-rastering stepper motor apparatus coupled with LVDTs (Linear Variable Differential Transformers), and nuclear signal processing and high speed data acquisition sections. Imaging of bulk material samples may be enabled by scanning a positron point source across a surface of samples. In another part of the irnplenientation, the instrumentation setup may comprise an electromagnetic deflection control arrangement in conjunction with a guided monoenergetic positron beam together with nuclear signal processing and data acquisition arrangements. This part of the implementation may scan and produce images for thin film samples. The instrumentation setup is capable of producing high quality real-time S-parameter images.

Abstract: A method and system for assigning self-routing addresses to nodes in a network with arbitrary, including irregular, topology is provided. The method and system are useful in packet-switched networks and in particular optical packet-switched networks for reducing processing associated with routing packets. Each self-routing address encodes a set of paths from all nodes in the network to the destination node. In an embodiment of the invention each output port of each node in a network sends a packet in response to the state of a bit in the self-routing address in a packet. Alternatively, each node address in the network is mapped to a bit in a self-routing address. Furthermore, a node can have multiple self-routing addresses encoding different sets of paths from all other nodes in the network to the node. In addition, hierarchical networks are included among the networks suitable for self-routing addresses.

Abstract: Embodiments of methods, apparatuses, devices and/or systems for manipulating hierarchical sets of data are disclosed. In particular embodiments, such hierarchical sets of data may be expressed as trees and/or strings. Further, such trees and/or strings may be associated with numerals. In other particular embodiments, operations on numerals associated with trees may be associated with manipulations of such trees.
Abstract: An imaging apparatus may comprise a lens assembly including one or more lenses, an image sensor to receive light from the lens assembly, and an actuator to adjust a position of the lens assembly. An actuator may be mounted on an image sensor, wherein a surface area of the actuator need not extend substantially beyond a surface area of the image sensor.

Abstract: Example embodiments for verifying an erase operation for a flash memory device may comprise, for one or more embodiments, utilizing program operation verification circuitry to verify, at least in part, the erase operation.
Abstract: Embodiments for clock and/or data recovery may comprise two or more samplers to sample a relatively small number of distinct data sample phase locations of a data pulse relative to an estimate of the location of a center of the data pulse. Signal level values for the sample phase locations may be compared, and sample locations for one or more other data pulses may be adjusted based at least in part on the comparisons.
Abstract: Subject matter disclosed herein relates to multilevel flash memory, and more particularly to a method of changing a logic level of a single-bit-per-cell flash memory device multiple times before an erase operation.
Abstract: Methods and apparatuses are provided for dynamically reorganizing the data within a replicated database system. One method, for example, includes performing a split operation across a plurality of replicated databases with regard to an existing partition therein, wherein the existing partition comprises a plurality of data records and the two new partitions each include at least a portion of the plurality of data records, and allowing at least one type of access to the plurality of data records during the split operation.

Abstract: A sense amplifier may be used to measure voltages and/or currents that represent logic levels stored in memory cells of memory devices. Accuracy and stability of such measurements may be improved by selective switching to isolate sense amplifiers from other portions of a circuit.
Abstract: Embodiments of methods, apparatuses, devices and/or systems for manipulating hierarchical sets of data are disclosed. In particular, methods, apparatus devices and or/or systems for analyzing hierarchical data are disclosed. In a particular example, rooted partial subtrees of partial subtrees of a tree are enumerated and associated with target numerals according to an association of trees and numerals. A probe numeral, representing information of interest, may be compared with target numerals to find a match. In one particular example, such a match indicates a presence of particular information in the tree.
