Abstract: An image is conceptually divided into pixel blocks each having a plurality of pixels. RGB image data representing the image are converted into luminance data and color difference data in the NTSC form. Standard deviation values of these data are calculated in each pixel block and are compared with threshold values, so that the pixel blocks are classified into two types. The image data in the pixel blocks of respective types are compressed at different compression rates to obtain image data compressed.

Abstract: An improved electrically erasable and programmable read only memory (EEprom) structure and processes of making it which results in a denser integrated circuit, improved operation and extended lifetime. In order to eliminate certain ill effects resulting from tolerances which must be allowed for registration of masks used in successive steps in forming the semiconductor structures, spacers are formed with reference to the position of existing elements in order to form floating gates and define small areas of these gates where, in a controlled fashion, a tunnel erase dielectric is formed. Alternatively, a polysilicon strip conductor is separated into separate control gates by a series of etching steps that includes an anisotropic etch of boundary oxide layers to define the area of the control gates that are coupled to the erase gate through an erase dielectric. In either case, the polysilicon layer strip can alternatively be separated by growing oxide thereon until it is completely consumed. A technique for forming a pure oxide dielectric layer of uniform thickness includes depositing a thin layer of an undoped polysilicon material and then oxidizing its surface until substantially the entire undoped polysilicon layer is consumed and made part of the resulting oxide layer. Overlapping doped regions are provided in the substrate by an ion implantation mask that adds spacers to the mask aperture to change its size between implants.

Abstract: In a delay measuring circuit (10), an input clock signal (13) is applied to a multitapped delay line (14), the output taps of which are connected to a switch (26) which selects one of the switch inputs for connection to a phase comparator (34) which compares the input clock signal (13), delayed in a delay device (38) to compensate for the delay inherent in the switch (26), with the output of the switch (26). The input clock signal is also applied to a counter (22), and when the phase comparator (34) detects a phase match, the counter value is stored in a latch (32), the counter 122) is reset to a predetermined value, and the counting procedure resumed. The latch (32) thus always stores a value dependent on the delay of an individual delay cell (16-1 to 16-N). This stored value can be applied to various uses, such as in a timing watchdog circuit or for generating accurate delays.

Abstract: Disclosed is a computer network node discovery system (120) that provides a general way of discovering network elements, or nodes (100), connected to a computer network (118), and a specific algorithm for discovering nodes connected to a TCP/IP network, using the SNMP protocol available within the TCP/IP network software. Some nodes on a network, called discovery agents, can convey knowledge of the existence of other nodes on the network. The network discovery system queries these agents and obtains the information they have about other nodes on the network. It then queries each of the nodes obtained to determine if that node is also a discovery agent. In this manner, most of the nodes on a network can be discovered. The process of querying discovery agents to obtain a list of nodes known to the discovery agents is repeated at timed intervals to obtain information about nodes that are not always active. In a TCP/IP network, discovery agents are nodes that respond to queries for an address translation table which translates internet protocol (IP) addresses to physical addresses. The data from each node's address translation table is used to obtain both the IP and the physical address of other nodes on the network. These nodes are then queried to obtain additional information. After all the nodes on a network are discovered, the list of nodes is written to a database where it can be displayed by the network manager or other users of the network.

Abstract: A method and apparatus for linear vocal control of cursor position within a computer display system. A microphone is utilized in conjunction with a computer system to detect vocal utterances and each vocal utterance is then coupled to an analysis circuit to detect voiced and unvoiced vocal utterances. Variations in the pitch of each voiced vocal utterance and the virtual frequency of each unvoiced vocal utterance are then utilized to linearly vary the position of a cursor in the computer display system in two axes independently. In a depicted embodiment of the present invention the analysis circuit includes a short delay to ensure that a valid control signal has occurred. Thereafter, increases or decreases in pitch or virtual frequency from an initial value are utilized to initiate movement by the cursor in a positive or negative direction in the two axes. Cursor motion will persist until pitch or virtual frequency return to an initial value or until the utterance ceases. In one embodiment of the present invention the appearance of the cursor is graphically altered to indicate the presence of a valid control signal.

Abstract: This invention method is characterized in that, instead of judging a noise only from an objective pixel and its neighboring pixels, the method judges whether or not a group of black pixels (including isolated points) is a noise from the number of pixels of the group, flattening and curvature, and that it can erase a noise of basically plural pixels. Since this invention method scans all the regions once, detects all the black pixel groups of the different size from small to large, and selects and takes out the black pixel groups meeting predetermined levels after detection, noise levels may easily be changed in parts. Since the size and shape may be designated in addition to a pixel, this invention method is highly effective for printing.
