Publication number: 20160285568Abstract: A system suitable for use in classifying radio signals includes a plurality of feature extractors configured to extract a plurality of features from an object and a plurality of classification layers. Each of the plurality of classification layers includes one or more reduced enhanced Gaussian classifiers selected from a plurality of Gaussian classifiers based on a classification error rate of each of the plurality of Gaussian classifiers and configured to classify the object as belonging to an object class in a subgroup of correctly classified object classes or in a disjoint error subgroup that needs further classification, using at least one of the extracted plurality of features. If the object is classified as belonging to an object class in a disjoint error subgroup at a layer, the object is passed on to a different reduced enhanced Gaussian classifier in a next layer for further classification.Type: ApplicationFiled: November 4, 2015Publication date: September 29, 2016Applicant: DRS ICAS, LLCInventor: Neil Judell

Publication number: 20130342833Abstract: An optical collection and detection system for use in a surface inspection system for inspecting a surface of a workpiece. The surface inspection system has an incident beam projected through a back quartersphere and toward a desired location on the surface, which is a scanned spot having a known scanned spot size. The incident beam impinges on the surface to create scattered light that is collected by a collector module. The collector module includes collection optics for collecting and focusing the scattered light to form focused scattered light. A collector output slit is positioned at an output of the collector module, through which the collection optics focus the scattered light. The scattered light that is associated with the scanned spot forms an imaged spot at the collector output slit.Type: ApplicationFiled: August 12, 2013Publication date: December 26, 2013Applicant: KLA-TENCOR CORPORATIONInventors: Neil Judell, Ian T.

Patent number: 8601268Abstract: Described are a system and method for securing an online transaction. A request is output from an electronic device to a verification server to perform an online transaction. The verification server generates a challenge request. The challenge request is encrypted with a private key of a pair of cryptographic keys. The encrypted challenge request is decrypted with a public key of the pair of cryptographic keys. The decrypted challenge request and the challenge request generated by the verification server are compared. A verification result is generated in response to the comparison.Type: GrantFiled: March 17, 2011Date of Patent: December 3, 2013Assignee: ID Security, LLCInventor: Neil Judell

Patent number: 8553215Abstract: An optical collection system for use in a surface inspection system for inspecting a surface of a workpiece. The surface inspection system has an incident beam projected through a back quartersphere and toward a location on the surface of the workpiece to impinge on the surface. This forms a reflected beam that extends along a light channel axis in a front quartersphere, and forms scattered light having a haze scatter portion. The incident beam and the light channel axis form an incident plane. The optical collection system includes back collectors that are positioned in the back quartersphere for collecting the scattered light, where each of the back collectors is disposed in the back quartersphere outside the incident plane, and at a relative minimum in the Rayleigh scatter.Type: GrantFiled: December 10, 2012Date of Patent: October 8, 2013Assignee: KLA-Tencor CorporationInventors: Richard E.
