摘要： A method and system for use in an air acoustic system for determining and using beamform factors for forming air acoustic beams approximating an optimum air acoustic beam for the directional transmission or reception of air acoustic energy by an air acoustic phased array system. Maximum and minimum dependent beamform factors of an optimum beam are determined from initial beamform factors and an initial parent population of chromosomes is generated, each chromosome including a gene corresponding to a dependent beamform factor and representing an initial candidate beam and subsequent parent populations are generated by cloning of the chromosomes of surviving populations. A child population is generated from a parent population by exchanging statistically selected pairs of genes of the parent population and generating a mutated population from the child population by mutating statistically selected genes of the child population. A surviving population is selected from the mutated population by comparing the chromosomes of the mutated population with a fitness criteria and selecting the chromosomes of the mutated population meeting the fitness criteria. When a chromosome of the surviving population meets the solution criteria, the genes of the surviving population having the best match to the fitness criteria are selected to forming a beam. The solution criteria may be a predetermined number of iterations of a surviving population or a predetermined tolerance of difference between a current and a preceding surviving population.

摘要： Sonar method and system for determining and using beamform factors for forming sonar beams approximating an optimum sonar beam for the directional transmission or reception of sonar energy by a sonar phased array system. Optimum maximum and minimum dependent beamform factors are determined from initial beamform factors and an initial parent population of chromosomes is generated, each chromosome including a gene corresponding to a dependent beamform factor and representing an initial candidate beam. Subsequent parent populations are generated by chromosome cloning. A child population is generated from a parent population by exchanging statistically selected pairs of genes and generating a mutated population. A surviving population is selected from the mutated population by a chromosomes comparison. When the surviving population chromosomes meet the criteria, the best match genes of the surviving population are selected for forming a beam. The criteria may be a predetermined number of iterations or a predetermined tolerance difference.

摘要： A communication and position determining device for use in an underwater communication and position determining system wherein the device transmits a sequence of one or more data words, wherein each data word includes a plurality of data bits transmitted in parallel as a corresponding number of concurrently transmitted signals, each of which occupies a different frequency band. The signals have waveforms selected from a pair of fade resistant waveforms that can be discriminated from one another, to represent binary data and the frequency bands are separated from one another by guard bands having widths sufficient to prevent intersymbol interference between the signals representing the data bits of a data word due, for example, to doppler and phase/frequency shifting, and successive data words are separated sequentially in time by intervals having a duration sufficient to prevent intersymbol interference between the signals of successive data words due to multipath reverberation. A single one of the signals of a data word is used for position determination wherein two devices each determine the bearing to one another from the bearing of the signals received from the other and a round trip propagation time determined from the time delay in transmitting an interrogation data word, a first response data word and a second response data word. Various alternative implementations of the invention are described.

摘要： An industrial work order analysis system applies statistical and machine learning analytics to both open and closed work orders to identify problems and abnormalities that could impact manufacturing and maintenance operations. The analysis system applies algorithms to learn normal maintenance behaviors or characteristics for different types of maintenance tasks and to flag abnormal maintenance behaviors that deviate significantly from normal maintenance procedures. Based on this analysis, embodiments of the work order analysis system can identify unnecessarily costly maintenance procedures or practices, as well as predict asset failures and offer enterprise-specific recommendations intended to reduce machine downtime and optimize the maintenance process.

摘要： In a radio access network, a drift radio network controller (DRNC) [262] transmits to a serving radio network controller (SRNC) [261] either (1) a filtering rule for a candidate cell [so that the serving radio network controller (SRNC) can generate a measurement list for a user equipment unit having a connection controlled by the serving radio network controller (SRNC)], or (2) a list of cells qualifying [according to filtering rules stored at and applied by the drift radio network controller (DRNC)] for inclusion in the measurement list for the user equipment unit. The filtering rule provides criteria useful for determining whether the candidate cell qualifies for inclusion in the measurement list of cells for the user equipment unit. If the candidate cell is a shared cell or cell for which the user equipment unit otherwise has permission for usage, the candidate cell qualifies for inclusion in the measurement list for the user equipment unit. On the other hand, if the candidate cell is a unshared cell for which the user equipment unit has no permission for usage, the candidate cell does not qualify for inclusion in the measurement list for the user equipment unit. The filtering rule itself can take various forms, and the filtering rule-bearing Iur message can have various formats possibly with transmission economizing features of the invention. In one mode of the invention, the drift radio network controller (DRNC) may itself apply the filtering rule to determine whether the candidate cell qualifies for the measurement list. In a hybrid mode, filtering functions are initially performed by the serving radio network controller (SRNC) and subsequently performed by the drift radio network controller (DRNC).

摘要： The invention relates to a receiver optical sub-assembly (ROSA) for use in an optical transceiver to convert optical signals transmitted along an optical fiber into electrical signals for use by a host device. Conventionally, light exiting the optical fiber inside an optical coupler of the ROSA encounters a refractive index mismatched interface, e.g. fiber/air, causing a portion of the light to be reflected directly back into the fiber. To minimize back reflections at the interface with the optical fiber, an optical insert is provided having an index of refraction matching that of the optical fiber, thereby moving the mismatched interface remote from the end of the fiber to an interface of the optical insert and a lens, to which the optical insert is attached.
