  • Patent number: 10295187
    Abstract: A fuel nozzle for a gas turbine engine is disclosed which includes a nozzle body having a longitudinal axis, an elongated annular air passage defined within the nozzle body, and a plurality of circumferentially spaced apart axially extending swirl vanes disposed within the annular air passage, wherein each swirl vane has multiple joined leads and a variable thickness along the axial extent thereof.

  • Patent number: 5737456
    Abstract: A method for processing a digitized image is described. The method includes the step of first generating a digitized image using an image-measuring system and representing the image as a vector g. A point spread function (PSF), represented as the function k(x,y,z), is also determined, with the PSF containing sub-pixels having a closer spacing than points in the g. Both the vector g and the function k(x,y,z) are then processed by: (a) selecting a vector c; (b) calculating the value of ##EQU1## using the vectors g and c, and the function k(x,y,z); and, (c) iteratively repeating steps (a) and (b) to determine a value for c that minimizes .PSI.(c). The image is then reconstructed by substituting in ##EQU2## the value for c that minimizes .PSI.(c) so that the processed image contains sub-pixels having a closer spacing than the points of the vector g.

  • Patent number: 5047968
    Abstract: An image restoration device restores images which are viewed through an optical member and stored in a data processor. Processing means associated with the data processor iteratively determine, for each point in a viewed image, a factor which minimizes noise and distortion at that point. The factor is iteratively determined through a division operation of a transform of a first function of a response function of the optical member and a transform of a second function of the response function. Preferably, the transform is a Fourier transform and the response function is the point spread function of the optical member. The processing means displays the restored image on a suitable display unit (e.g. a CRT).

  • Patent number: 5009488
    Abstract: A microscope is modified to allow for precise imaging of samples using different filters at different focal planes under computer control. A filter accessory includes a filter disc having bandpass filters. The filter disc may be rotated to move a selected filter into the optical path between a light source and the microscope sample. Adjustment of the image plane of the microscope is controlled by the computer using feedback from a lens position sensor.

  • Patent number: 4884225
    Abstract: A series of spacial filters are used in a convolution process to determine location, size and orientation of bodies in an image. One series of spacial filters of different sizes is used to determine location and size. A second series is used to determine orientation and is a series of varying density, overlapping spacial filters. In particular, the series of spacial filters determines the spherical coordinants (r, .theta., .phi.) of bodies in an image of a muscle cell. The series of overlapping filters in one design have vector responses such that a resultant vector is defined. .phi. equals the angle of the resultant vector and .theta. is proportional to the length of the resultant vector. A series of one and two dimensional differential gaussian filters determine the cell boundaries.

  • Patent number: 4744667
    Abstract: An accessory is provided to convert a conventional microscope to a microspectrofluorimeter. The accessory includes a filter disc having bandpass filters separated by opaque segments. The filter disc is rapidly and continuously rotated to move the filter sequentially into the optical path between a wideband light source and a microscope sample. Photon counting of radiation from the sample is synchronized to the position of the filters during rotation by means of synchronization marks on the filter disc. The same accessory may be positioned between the sample and a detector to detect emitted light of different frequencies.
