Title: Computer-implemented method for automatic extraction of data from printed forms
Inventor: CASEY RICHARD G
IPC: G06K9/20
Filed: 1989-10-02
Granted: 1995-03-21
Abstract: A computer-implemented method operable with conventional OCR scanning equipment and software, extracts character data from printed forms.    A blank master form is scanned and its digital image stored.          Clusters of ON bits of the master form image are first recognized as part of a line and then connected to form lines.  All of the lines in the master form image are then identified by row and column start position and column end position, thereby creating a master-form-description.  The resulting image, which consists only of lines in the master form, can then be displayed.  Regions or masks in the displayed image of master form lines are then created, each mask corresponding to a field where data would be located in a filled-in form.  Each data mask is spaced from nearby lines by a predetermined data margin, referred to as D.    A filled-in or data form is then scanned and lines are also recognized and identified in a similar manner to create a data-form-description.  The data-form-description is compared with the master-form-description by computing the horizontal and vertical offsets and skew of the two forms relative to one another.  The created data masks, whose orientation with respect to the master form has been previously determined, are then transposed into the data form image using the computed values of horizontal and vertical offsets and skew.  In this manner, the data masks are correctly located on the data form so that the actual data values in the data form reside within the corresponding data masks.  Routines are then implemented for detecting extraneous data intruding into the data masks and for growing the masks, i.e. enlarging the masks to capture data which may extend beyond the perimeter of the masks.  Thus, the data masks are adaptive in that they are grown if data does not lie entirely within the perimeter of the masks.  During the mask growth routine, lines which are part of the background form are detected and removed by line removal algorithms.    Following the removal of extraneous data from the masks, the growth of the masks to capture data, and any subsequent line removal, the remaining data from the masks is extracted and transferred to a new file.  The new file then contains only data comprising characters of the data values in the desired regions, which can then be operated on by conventional OCR software to identify the specific character values.

Title: Display apparatus for alphanumeric displays
Inventor: KILLINGER ERICH
IPC: G09F9/30
Filed: 1990-03-21
Granted: 1995-04-18
Abstract: This invention relates to a display apparatus for alphanumeric displays having a display panel.  A controllable light source illuminates a bundle of optical fibers and in which one switch element is triggerable from a control line.  The switch element is introduced into each light path leading from an optical fiber to a display element, and with the switch element the associated light path can be selectively opened or blocked.  A multi-color representation of the displays is attained by each display element of the display panel having a variable number of light paths.  The display elements are disposed in the same variable number of internested matrices.  The optical fibers associated with one matrix are joined into bundles and are illuminated by separate light sources.  The control lines of the switch elements are individually triggerable for the various matrices with a control unit in order to represent the variable number of alphanumeric displays or a multi-color alphanumeric displays simultaneously, where in the latter case filters are connected to the output side of the light sources or optical fibers.

Abstract: A method of and an apparatus for manufacturing a woven stringer for a concealed type of slide fastener having a row of continuous filamentary coupling elements woven integrally into a stringer tape.  The row of coupling elements are formed into a continuous helical coil structure which is woven into a longitudinal edge of the stringer tape as the latter is woven and which is oriented so that each of the coupling elements has its heel portion disposed to project transversely beyond the longitudinal edge of the stringer tape and its coupling head portion directed toward a web portion of the tape when the stringer is produced.  The resulting stringer when in use is folded back on a longitrudinal axis so that the coupling head projects beyond the tape edge but is concealed from view when a pair of such stringers are coupled together.

Granted: 1994-09-20
Abstract: A diplexer  for electromagnetic  signals  of higher  and lower frequency is formed of a common waveguide channel for both signals,  the common channel branching into a through waveguide channel and a side waveguide channel. The through channel includes a filter having a pass band for  propagation  of  the  lower  frequency  signal  and inhibiting propagation of the higher frequency signal. The side channel is formed as a waveguide below cut-off frequency with respect to the lower frequency signal for inhibiting  propagation  of  the lower  frequency  signal while  permitting  propagation  of  the  higher  frequency signal.  A coupling aperture formed as a slot resonant at the higher frequency is located in a waveguide wall at an integral number of quarter guide wavelengths in front of the  filter  for  coupling  the  higher  frequency  signal between the common and the side channels.

Title: Electronic control for monitoring status of a compressor
Inventor: ROLLINS DOUGLAS JAY
IPC: G05D16/20
Filed: 1990-05-04
Granted: 1998-05-12
Abstract: The compressor controller includes a timing circuit  for  timing-out  a  detected  fault  in  a compressor.  Upon the fault existing for longer than a predetermined time limit,  the controller removes power from the compressor.  If the fault is corrected within  the  predetermined  time  limit,  even momentarily, the timing process is discontinued and the controller continues to monitor the status of the compressor.   The controller also includes a delay timer  for  delaying  the  re-energizing  of  the compressor after an interruption or loss of power occurs.   The delay prevents short cycling of the compressor.  The controller further includes a status display  for  indicating  compressor  functions, connections to an alarm which is initiated in the event of compressor failure, a switch for initiating a self test of the controller, and circuitry for a field applied current sensing relay.
