摘要： A video interface apparatus for converting an incoming interlaced video signal to an outgoing non-interlaced video signal for an LCD flat panel with an arbitrary number of rows and columns. The incoming video signal is digitized and stored in a memory. An address generator creates addresses for reading and writing data from and into the memory, and the resulting read data is used to reconstruct the digital signal into an image for display on the LCD flat panel.

摘要： An electronic interface for converting an interlaced video signal to a non-interlaced video signal suitable for an LCD flat panel. An analog interpolator scheme is used in which the information available in an incoming video scan line is delayed and sampled, and output signals are created by interpolation between the sampled input and actual and interpolated scan line signals. The output signals are then converted into an integrated, sequential non-interlaced output signal having a frequency corresponding to the horizontal resolution of a scan line of the flat panel.

摘要： A computer aided biological specimen screener is responsive to a priori information about biological specimens. An automated slide classifier scans a slide specimen and generates a set of scores. The classification which results from this set of scores depends on a priori information concerning the patient, such as patient age and prior health history and diagnosis. Using the patient information and an appropriate score, the specimen is classified. A normal threshold used for classification is changed over a wide range depending on the specificity appropriate to a particular patient risk category. The sensitivity of the classification is automatically maximized for a predetermined normal specificity.

摘要： A photographic facsimile of a line image at a predetermined orientation is illuminated by a collimated monochromatic light source to produce a diffraction pattern. The Fourier distribution of the diffraction pattern is focussed by a converging lens to image on a spatial frequency plane of spatial signal and spatial noise components. The image in the spatial frequency plane is applied to a detector for selectively measuring the spatial power contribution of the signal and noise components, thereby to provide a measure of image quality relating to imaging system signal-to-noise ratio. A spatial filter (18) may be introduced into the optical path to block the spatial signal components, while allowing the noise components to impinge on the detector. The line image is then reoriented in the image plane, and successive measurements of spatial signal and noise contributions repeated. The ratio of signal-to-noise power is then computed for each orientation of the line image. By simulating selected imaging components and generating a resultant line image, the effect of such components on noise may be determined.

摘要： The disclosure is directed to a color liquid crystal display backlight system for daytime and nighttime use. Night vision imaging system retirements are met so that light emissions from the 630 nm to 930 nm range are substantially reduced or eliminated. Separate daytime and nighttime light sources are utilized. The NVIS compatible nighttime source is positioned to be out of sight of a user and produces an appropriately filtered, substantially collimated beam which diffusively reflects from the inside walls and base of the display housing before it illuminates the display surface. Intensities of both daytime and nighttime light sources can be controlled.

摘要： A fiber optic transmission system including a fiber optic link. Transmitting apparatus transmits an optical signal having a concentration of energy at a particular wavelength. Routing apparatus then routes optical signals in response to the concentration of energy at the particular wavelength of the transmitted optical signal. The routing apparatus is disposed to receive the transmitted optical signal and also reflects a small portion of the transmitted optical signal. A first apparatus for receiving the reflected portion of the optical signal is disposed to cooperate with the routing apparatus and further has apparatus for converting the reflected portion into a control signal. Temperature sensing apparatus is disposed to sense temperature variations in the first receiving apparatus and apparatus for controlling the transmitting apparatus is adapted to receive the control signal and further is disposed so as to regulate the transmitting appratus responsively to the control signal. The controlling apparatus further operates to regulate the power of the transmitting apparatus as a function of temperature sensed by the temperature sensing apparatus so as to maintain a preselected power margin in the fiber optic link.

摘要： An analysis system has a first region in which sample materials are stored at an appropriate storage temperature and an analysis region which is maintained at a controlled and stabilized temperature higher than the temperature of the first region. Transfer mechanism for transferring a quantity of sample material from the first region for loading into an analysis cuvette in the analysis region includes a liquid handling probe that is mounted on a probe transport carriage, and a drive for moving the transport carriage between the first and second regions. The transport carriage includes a storage chamber connected to the liquid handling probe, thermal energy supplying means in heat exchange relation with the storage chamber, and thermal sensor means carried by the transport carriage. Means responsive to the thermal sensor supplies thermal energy to the transport carriage to maintain the storage chamber at substantially the same temperature as the analysis region.

摘要： A programmable color enable and sequencing system for a sequential color and memory television system is provided. An output for sequencing the sequential colors of the SECAM system in a decoder and enabling color if chrominance is present is generated by statistically detecting the presence of color information and, using the same statistical detector, provides for synchronization of the color sequence circuits. The statistical detection uses FM information provided during the vertical interval and/or information contained in the color subcarrier of the composite SECAM signal. Additionally, the system includes means for providing a preprogrammed color enable for each one-half line defined according to user needs or system standards for enabling instantaneous decisions about which lines of the composite signal are color. Decisions as to whether or not the overall picture is color are made by the statistical detector.

摘要： A vibration isolation system for the antenna of a vehicle, such as a maritime vessel. The vibration isolation system has a staged construction that slidably attaches the maritime antenna to a maritime vessel along up to three independent axes of translation. This staged construction is adapted for independently decreasing movement of the antenna along the independent axes of translation. Accordingly, the staged construction prevents the antenna from rotating due to induced translational vibration and thus enhances the pointing performance for the antenna.
