Inventor: BAEK SEUNG HO
IPC: G06K15/02
Filed: 1992-06-24
Abstract: A method and apparatus are disclosed for scanning a receiving medium. The present invention can be used in scanner apparatus in which a diode laser is modulated by a drive current which is controlled in accordance with a digital information signal. Radiation from the diode laser is imaged onto a receiving medium such as a thermal print medium. In order to overcome the problem of artifacts in images produced by such apparatus, random noise is used in the apparatus to mask the image artifacts. In one embodiment of the present invention, an error signal, provided by a random noise generator, is injected into the drive current for the diode laser. In a second embodiment, states of bits in the digital information signal are randomly changed in order to randomly change the laser drive current.

Abstract: On detecting a carrier frequency error in a received signal, a correlation unit (12) detects a correlated signal in signals which a transmission unique word signal in the received signal and a local unique word signal are differentially detected. A frequency fine detection unit (17) detects a fine frequency error by using the correlated signal and a frame timing signal. A frequency coarse detection unit (21) detects a coarse frequency error by using the buffered signal from a data buffer (20) and the frame timing signal. A first adder (25) adds the fine frequency error to the coarse frequency error to a first added signal. A second adder (31) adds the first added signal to a maximum power frequency detected by a maximum power frequency detection unit (27) to produce the carrier frequency error.

Abstract: An apparatus and process for removing blowing agent from polymeric foam. The apparatus comprises a comminution zone into which extraction liquid and polymeric foam may be introduced. The upper end of the zone is of larger cross-sectional area and tapers to a lower end of a smaller cross-sectional area. Comminuting means are located within the comminution zone, and are adapted to comminute the polymeric foam and impart a vortex to the liquid and foam. A quiescent zone is directly connected to the lower end of the comminution zone so that comminuted polymeric foam and extraction liquid may be passed directly from the comminution zone to the quiescent zone. Attenuating means for attenuating the vortex created in the comminution zone are located within the quiescent zone. The foam then rises to the top of the quiescent zone and is removed.

Abstract: A tool (1) for subcutaneously implanting a subcutaneous electrode comprising several wire patch electrode segments by way of a single surgical incision. The tunneling tool (1) comprises a stylet (2) and a peel-away sheath (8). The tunneling tool (1) is inserted into an incision, in a direction which corresponds to the desired placement of an electrode segment. Once the tunneling tool reaches a desired position, the stylet (2) is withdrawn, thereby revealing the interior of the peel-away sheath (8) and a resulting subcutaneous tunnel. The corresponding electrode segment is then inserted into this subcutaneous tunnel, and subsequently implanted in the patient. The implantation procedure is then repeated as many times as is necessary, using the same incision, until all the electrode segments for the particular electrode configuration have been implanted. In addition, the tunneling tool (1) can be adapted to conform to varying electrode segment sizes, which thereby allows the tool to conform to the varying needs of each individual patient. As an even further feature, the tunneling tool (1) can be constructed in a curved configuration to facilitate electrode implantation in the lateral thoracic region of the body.

Abstract: A method, system and program for allowing an application designed to use static method calls to manipulate objects whose methods are only available through dynamic calls without modifying the binary image of the application. A SOM compiler generates class definitions and generates a redispatch stub for each method defined in a class. A redispatch stub is a short sequence of instructions with an identical calling sequence as its corresponding method. This gives the class' dispatch enough information to determine the correct method procedure in a dynamic manner. The dispatch function employs the redispatch stub to call the appropriate method procedure and return any return value to the calling application via the redispatch stub. Redispatch stubs allows a class with a definition that can vary at runtime to be used by an application that was designed for statically defined classes.

Abstract: A method and apparatus for building and using tables which determine the colors to be printed from a device independent color coordinate system. Two tables are built: the first is a printer table for colors in the printer gamut as well as for colors in a typical color monitor gamut, and the second is a border table for colors outside the printer table. The printer table is constructed from a mathematically smooth mapping function for mapping from the device independent coordinate system (such as CIELAB space) to the printer coordinate system, and the mathematically smooth mapping function is determined based on a measurement of the printable colors in the device independent coordinate system. The border table is constructed so as to preserve the hue of unprintable colors but to increase saturation so as to achieve a more natural looking result. The increase in saturation is limited so that the change in luminance does not exceed a predetermined threshold. Preferably the printer table is organized as a rectangular grid that includes the gray axis of the device independent color coordinate space, while the border table is arranged as wheel-shaped cells centered on the gray axis and accessed in accordance with the hue angle of the unprintable color. Transition colors are added to the printer table outside the printer gamut, smoothing the transition from the edge of the printer gamut to the border table and also preserving color differentiation outside the printer gamut. In use, either the printer table or the border table is selected based on whether the desired color in the device independent coordinate system is within the printer table or outside the printer table. According to the invention, it is possible to reproduce accurately the colors in the printer gamut and also to print pleasing colors for those colors which are outside the printer gamut.

Abstract: A method and apparatus for reordering windows and window objects with primary application in a multiple window environment in an information processing system. The windows or window objects may be reordered sequentially or according to some hierarchical relationship among the windows. Each window in the multi-window display contains a system menu icon which may be selected for providing a choice to reorder the windows on the display according to either sequence or hierarchy. A user selects the system menu icon in any one of the opened windows on the display. One or more window counters is incremented each time a window or window object is opened on the display. A window counter value is then assigned to each window so that it can be readily reordered. Reordered windows and window objects are typically displayed in a cascaded configuration on the display screen.
