Abstract: Cable interconnection terminated by a pin or socket includes a housing, an inner conductor arranged in the housing and having a first end adapted to couple to the pin or socket, and an outer sheath adapted to couple to an outer sheath of a cable including at least one conductor, e.g., a coaxial cable, twin-axial cable or tri-axial cable. The interconnection also includes first and second pins. The first pin is arranged at a second end of the inner conductor while the second pin is electrically connected to the outer sheath. The first and second pins each have a mating portion, and both mating portions terminate at a common plane a set distance from the housing. This termination in a common plane, substantially perpendicular to the axial direction of the pins, enables the cable to mate with a wide range of electronic componentry.

Abstract: Method and sequence for locating anomalous features in medical images in which medical images are supplied by an external source such as a CAT or XRAY scan machine or other similar device. A sequence of specific measurements is executed on the supplied data to obtain metrics relating to the images. The metrics are then compared to the corresponding values in an accompanying database resulting in an anomalous/not anomalous determination. Anomalous determinations are presented to the test operator for final analysis along with supplemental historical data. In application to all types of medical imagery, potential anomalies are quickly located resulting in an efficient and more accurate diagnosis.

Abstract: Method and system for testing any type of video display, video monitor or other device that produces a video signal, and that is capable of providing information about the video and optionally audio specifications and/or capabilities of the output signal to an external device when coupled thereto. The external device obtains the information about the specifications and/or capabilities and based thereon, assembles one or more pre-defined tests from a test database/repository containing tests to enable testing of compliance of the video signal producing device to those specifications and/or capabilities. This compliance testing may entail generating video or audio content at a source generator, providing it to the video signal producing device, and determining the accuracy of the output of the video signal producing device to the input content. A determination of the results of this test may be provided to an operator of the testing apparatus.

Abstract: Method and modular system for generating and capturing DVI video signals. When generating a video signal, data blocks are arranged in a line parameter memory, each corresponding to a complete video line and containing pointers to specific entries for lines of the video signal in a primary image memory holding a main bit-mapped image, and a video line construct memory holding data enable and blanking patterns. Generation of the video signal is initiated by reading the line parameter memory and extracting pointers from the data blocks for a first line of the video signal being generated. Bits from the primary image and video line construct memories are obtained and combined based on extracted pointers to generate the first line of the video signal. A length of the first line of video signal is monitored to determine when it is complete, and then the process continues for each additional line.

Abstract: Method for validating a single waveform or series of waveforms that are intended for evaluating signals within an automated testing environment. Test signal data is supplied by an external source. The method creates a golden template from a known, good instance of the waveform under test and algorithmically applies it to other waveforms under test to determine compliance. In the application to video waveforms, timing parameters, deflection parameters and image content parameters are simultaneously tested resulting in efficient concrete and tangible results. Instead of providing the known, good instance of the waveform under test to a processor that implements the method, descriptive parameters of the known, good instance of the waveform may be provided to the processor that calculates data points of the expected video waveforms and then determines rules for the waveform based on the calculated data points.

Abstract: Method, system and computer program for visually highlighting identified failing or erroneous pixel elements of a two-dimensional electronic image. Different visual highlighting techniques are stored in memory. A user selects one of the highlighting techniques using a user interface. A processor applies the selected technique(s) to the image and displays the image on a display with visual indications of the failing pixel elements. The techniques include coloring the pixels with a boundary box enclosing all of the erroneous pixels, enclosing separate irregular-shaped groupings of the pixels with a contour-type boundary line, and coloring pixels and enclosing each within a separate box. In the final technique, video lines with some failing pixels, but within allowable tolerances, will have those pixels colored differently and each pixel is enclosed within the same color box. In all cases, it is possible to convert the test image to black and white for display.

Abstract: Method and system for validating video monitors, gauges, indicators and controls within their installed environment is disclosed. The methods do not require access to the electronic signals that control or stimulate those devices. Direct visual capture of the instruments under test is provided along with a novel sequence of operations to compare the present visual presentation to a known-good reference image and optionally, to known-bad reference images.

Abstract: Electron beam profile testing and analysis method is introduced using the MOMS apparatus. The MOMS apparatus includes a Faraday Cup with a knife-wires scanning system which together perform simultaneous measurements. The scanning system has a five-dimensional processing mechanism for measuring different cross sections of an e-beam profile in a path of the e-beam. Measurements are conducted using the scanning system by virtually dividing each cross section into a plurality of subsections and measuring independent current values of at least one wire of the scanning system through which the electron beam passes from every pixel in each of the plurality of subsections. By providing relative movement between the scanning system and e-beam, the measured independent current values are analyzed to obtain the functional form of distribution of current density of the cross-section of the e-beam. The Faraday cup enables simultaneous measurement of the total value of the current.

Abstract: Method and system to configure a common set of electronic components using software in order to simulate different electronic, mechanical and/or electro-mechanical instruments or instrument functions. For each instrument function or traditional mode of operation to be simulated, software models are created which when directed to the electronic components, cause the electronic components to respond to input in the same manner that the actual, traditional physical instrument would respond to satisfy the same test requirement input. The software models are preferably stored in a model repository which is searchable to enable a user to select the instrument function or traditional mode of operation to be simulated with the corresponding model being provided to the electronic components. Once the model, i.e., a function for each synthetic element, is downloaded and the electronic components configured according to the model functions, testing of the assemblies or other UUTs can begin.
