Abstract: A method and apparatus for enhancing an image for a display, first digitizes the image to produce a map of the image, this map containing pixels having 2 n  grey levels where n is the number of bits per pixel. The map of the image is then downsampled to produce a downsampled map of the image. Thresholding is then performed on the downsampled map of the image to reduce the number of bits per pixel from n bits to m bits to produce a thresholded downsampled map of the image, where m is less than n. The number of bits per pixel is restored from m bits to p bits, where p is greater than m, to produce a restored thresholded downsampled map of the image. The restored thresholded downsampled map of the image can be downsampled again to produce an image map suitable for display on a low to moderate cost display, such as a CRT, with grey scale capability. The displayed image has an enhanced appearance, since it is high fidelity with respect to the original.

Abstract: In an MSK transmitter, the digital data signal is split (11) into I and Q channels (121,122). Instead of applying these directly to the quadrature modulator (2), the I channel is applied first to an inverter (3), and the switch (4) selects either the I signal (121) or the inverted I (123) signal. The unaltered I signal is used when the local oscillator in the receiver is synchronous to that in the transmitter. Otherwise the inverted I signal is used.

Abstract: A common general parser and applications program interface for use in a data processing system. The parser encodes data from a program for transmission onto a channel and decodes incoming data for handoff to an applications program. Initialization of the parser includes allocating private storage for the individual data items to be encoded or decoded. The program requests data that is received by the parser or transmits data onto the channel by issuing a call to the parser. The call identifies the parse table to be used by the parser. In response, the parser encodes or decodes the data in accordance with the identified parse table to extract the individual data items. The parser stores the individual data items in their respective allocated storage areas for the program during decoding or extracts the data items from the storage for encoding.

Abstract: A data processing system (20) that prints characters using a raster-scan pixel representation employs an inversion technique to achieve the filling of interior pixels within a polygon. At intersections of segments (1-13) that define edges of the polygon, a common pixel may be shared by the last pixel of a first line segment and a first pixel of a second line segment. The inversion action is inhibited when considering the last pixel of the next segment. In this manner, double inversions that cause fill splinters are avoided. The data processing system (20) also employs a method for rendering vectors (150) with pen widths of varying magnitude where, based upon the angle of inclination of the vector (156), its end points (P1, P3, P2, P4) are derived. The end points are then modified by addition of integer offset values to take into account differences between given pen widths and pixel-integer pen widths. Then, resultant co-ordinate end points are revised to provide an approximately square end, based upon the found angle of inclination. A procedure is also described for assuring a best choice of a pixel (220) to turn ON at an intersection of line segments (S1, S2).

Abstract: In a switch mode power supply, a full wave rectified AC mains supply voltage (V1) is produced from an AC mains supply voltage (VM) without low-pass filtering. The unfiltered rectified voltage is applied to a winding (W1) of a flyback transformer (T) that is coupled to a switching transistor (Q1). A first plurality of current pulses (iP1) are generated in the winding from the rectified voltage at a frequency (20 KHz) that is higher than the frequency (50 HZ) of the mains supply voltage and at peak amplitudes that vary in accordance with the rectified voltage in a manner to increase a power factor. The rectified voltage is further rectified via a rectifier (D2) coupled in series with a resistor (R13) and a low-pass filter capacitor (C2) and produces current pulses (i3) in the capacitor. A voltage (V2) in the capacitor is coupled via a second switching transistor (Q2) to the winding to produce in the winding a second plurality of current pulses (iP2) that reduce a ripple component at an output (37) of the power supply. The resistor increases the pulse-width and decreases the magnitude of the capacitor current pulses in a manner to reduce input harmonic contents and increase the power factor.

Abstract: A transmission system is disclosed for transmitting digitized analog information. At the transmission side, for the purpose of transmitting an additional information signal, data words representing the digitized information are modified depending on the bits of an additional information signal. The modifying means (21,22) are constructed in such a way that the modification depends both on the additional information signal and on other bits (b7) which are not correlated with the bits (d) of the additional information signal. This results in the intercorrelation between the errors (Δ, e) in the data words introduced by the modification being reduced, so that a flatter power density error spectrum is obtained and the errors introduced in the data words by the modification are less conspicuous.

Abstract: A display apparatus is constituted by a display device including a plurality of scanning lines, a plurality of data lines intersecting the scanning lines, and a pixel formed at each intersection of the scanning lines and data lines and showing plural display states depending on signals applied to an associated scanning line and an associated data line. The display device is driven by applying a selection signal to the scanning lines and applying to the data lines data signals for causing prescribed display states at the pixels in association with the selection signal. Further, at least one scanning line in a nonselected state is supplied with a dummy signal for temporarily changing display states of pixels on the at least one scanning line, whereby flickering on the display device is suppressed. The display apparatus is also applicable to gradational display.

Abstract: A text-compression technique utilizes a plurality of word-number mappers ("WNMs") in a frequency-ordered hierarchical structure. The particular structure of the set of WNMs depends on the specific encoding regime, but can be summarized as follows. Each WNM in the set is characterized by an ordinal WNM number and a WNM size (maximum number of tokens) that is in general a non-decreasing function of the WNM number. A given token is assigned (52) a number pair, the first being one of the WNM numbers, and the second being the token's position or number in that WNM. Typically, the most frequently occurring tokens are mapped with a smaller-numbered WNM. The set of WNMs is generated on a first pass through the database to be compressed. The database is parsed into tokens, and a rank- order list based on the frequency of occurrence is generated. This list is partitioned in a manner to define the set of WNMs. Actual compression of the data base occurs on a second pass, using the set of WNMs generated on the first pass. The database is parsed into tokens, and for each token, the set of WNMs is searched to find the token. Once the token is found, it is assigned the appropriate number pair and is encoded (55). This proceeds until the entire database has been compressed.

Abstract: Power or ground voltage can fluctuate when many high capacitance terminals of an integrated circuit device move simultaneously from one logic state to another. This occurs particularly after release of a global high impedance state of output buffers where output signals have been passively driven to a selected logic state. To prevent supply and ground voltage variations, the buffers are provided with means for operating in a slow response (high slew) mode. A slew rate control circuit (229) moves the buffer (21) to slow response mode in response to the high impedance signal (GTSB). When the slew race control circuit (229) receives a signal ending the high impedance state of the buffer (21), it applies a delay to this signal, and after the delay time allows the buffer (21) to move to a fast response mode. The slow buffer response and resulting slow voltage change when high capacitance terminals move to a new logic state prevents fluctuation of power or ground voltage in response to simultaneous switching of many terminals.
