Abstract: A method and system of object classification uses measurements for a training set of objects to classify an unknown object as being a member in one of several classes of the training set. The classes are defined by features of the training set, the objects of which have known class memberships. The method comprises performing principal component analysis on the training set measurements to discard features that have negligible information regarding class membership, conducting projection pursuit on the remaining training set measurements to accentuate differences between the classes, estimating a distribution of each accentuated class in the training set, and evaluating measurements of the unknown object to determine the membership of the unknown object in one of the accentuated classes. The system implements the method in a computer program stored in computer memory.

Abstract: One embodiment of the present invention separates the region of measurement space into a plurality of sub-regions and calculates a confidence, for reconstruction of an underlying signal within said space, corresponding to each of the sub-regions. This embodiment can then accept measurements from mobile measuring devices within said measurement space and store those measurements if they originate from devices in sub-regions having a confidence below an acceptable value.

Abstract: A method and system for employing pixel-based, signal-intensity data contained within areas of a scanned image of a molecular array corresponding to features and feature backgrounds in order to determine whether or not the features or feature backgrounds have non-uniform signal intensities and are thus outlier features and outlier feature backgrounds. A calculated, estimated variance for the signal intensities within a feature or feature background is compared to a maximum allowable variance calculated for the feature or feature background based on a signal intensity variance model. When the experimental variance is less than or equal to the maximum allowable variance, the feature or feature background is considered to have acceptable signal-intensity uniformity. Otherwise, the feature or feature background is flagged as an outlier feature or outlier feature background.

Abstract: An apparatus for determining the wavelength of light emitted by, for example, a laser, includes three photodiodes. One photodiode receives a proportion of the light redirected from the main optical path by a beam splitter. A second photodiode receives a proportion of the light redirected from the main optical path by the beam splitter and passing through a broadband filter. A third photodiode receives light that has been caused to interfere by an interferometric device. The ratio of the light intensities at the first and second photodiodes provide a coarse determination of wavelength, when compared to a lookup table, and the ratio of the light intensities at the first and third photodiodes provide a more exact determination of the wavelength.

Abstract: An external cavity laser system includes an in-line optical filter and a reflection suppressor that efficiently suppresses back-reflected light while allowing light to resonate within the laser cavity. The reflection suppressor may include a polarizer that polarizes light within the cavity and polarization rotators that rotate the polarization state of the polarized light such that back-reflected light is suppressed by the polarizer. Because back-reflected light is suppressed, use of an in-line filter becomes viable in an external cavity laser system.

Abstract: A CPT detector and a method for detecting CPT are disclosed. The CPT detector includes a quantum absorber, a polarization analyzer, and a detector. The quantum absorber includes a material having first and second low energy states coupled to a common high energy state. Transitions between the first low energy state and the common high energy state and between the second low energy state and the common high energy state are induced by electromagnetic radiation having a predetermined polarization state. The polarization analyzer blocks electromagnetic radiation of the predetermined polarization while passing electromagnetic radiation having a polarization state that is orthogonal to the predetermined polarization. The polarization analyzer is irradiated with a portion of the generated electromagnetic radiation that has passed through the quantum absorber. The detector generates a signal related to the intensity of electromagnetic radiation that leaves the polarization analyzer.

Abstract: A coaxial connection is electromagnetically shielded at an interface between a surface mountable coaxial connector and a planar circuit operating in the radio frequency (RF) and microwave frequency ranges. In addition or alternatively, the coaxial connection reduces a potential impedance mismatch associated with attaching a coaxial transmission line of the coaxial connector to a planar transmission line of the planar circuit.

Abstract: An amplifier having first and second enhancement-mode Field Effect Transistors (FETs) is disclosed. The input port receives an input signal that is to be amplified. The source of the first FET is connected to the input port such that the first FET provides an input impedance match for a signal source connected to the input port. The gate of the second FET is connected to the drain of the first FET such that the second FET amplifies the output signal from the drain of the first FET to provide an amplified input signal. The first and second FETs form a current mirror. An output circuit provides a predetermined output impedance at an output port for coupling the amplified input signal to a circuit that is external to the amplifier. In one embodiment of the invention, the output circuit includes a third FET connected as a source follower with the second FET.

Abstract: The inventive mechanism manages packet delay values that a network incurs in transported data packets. The mechanism uses a plurality of bins for maintaining the number of times that delay values fall within the range of a particular bin. The mechanism also uses a storage array for maintaining delay values that do not fall with the range of the bins. For each delay value that is received, the mechanism determines whether the delay value falls within the bin range. If so, the mechanism increments the number of a particular bin into which the delay value falls within. If not, the mechanism stores the delay value in the storage array and effectively doubles the size of the range of the bins. The mechanism will then effectively re-slot the values into the scaled bins. This allows for the numbers in the bins to used to form graphs detailing the latency of the network for display to a user.

Abstract: A method and apparatus for managing a communication system including multiple links is presented. A receiver including a First-In, First-out (FIFO) memory receives information communicated on the links. A FIFO is associated with each communication link. Information is written into the FIFO based on a transmitter clock. Information is read out of the FIFO using a receiver clock. The FIFO is used to deskew data communicated across the communication links and re-synchronize the data between the transmitter clock and the receiver clock. A state machine controls the information read out of the FIFO. The state machine includes a deskew enabled state, a deskew disabled state and a reset state. Using the FIFO, the system is able to self reset and transition between the deskew enabled state and the deskew disabled state.

Abstract: The present invention is directed to a system and method in which management behavior within a network management system is represented as objects to allow for such management behavior to be dynamically defined. Management behavior may be dynamically created and/or modified by a user in various embodiments. Objects are used to represent management behavior, such as behavior associated with trap management and/or polling management. Such objects may be dynamically defined by a user and activated with the management system during system run-time, without requiring that the system be shut down to implement behavioral changes. The management system may be implemented with gateways distributed from a central management processor. Upon behavior objects being defined by a user, the system may determine appropriate gateways to receive the objects and autonomously communicate the objects thereto.

Abstract: Inverting optics are used to invert, with respect to the dispersion plane, the wavefront of a monochromator employing a beam making more than one pass through the dispersing medium. Further, the inverting functionality can be turned-on or turned-off, thereby reversibly converting between additive and subtractive monochromator architectures. Inversion reversal is accomplished by reorienting the inverting optics orthogonally about an axis coaxial with the beam, either back and forth or monotonically, or by displacing portions or all of the inverting optics into and out of the beam. Examples of inverting optics include Dove prisms and equivalent multiple all-reflective surfaces. The system and method can be applied to two-pass and other multi-pass monochromators and to dual and other multiple serial monochromator configurations using diffraction gratings or other dispersing elements.
