Provided is a knowledge extracting apparatus for extracting knowledge information related to a knowledge-extraction target from an electronic document distributed continually in a state where the electronic document is not associated with the knowledge-information extraction target. A knowledge extracting apparatus according to one embodiment is a knowledge extracting apparatus including: an information receiving section for receiving an electronic document; a knowledge extracting section for extracting a concept from the electronic document based on a target word to extract knowledge information and a clue word to extract knowledge information and forming knowledge information in which the concept thus extracted and the target word are associated with each other; a storage section for storing the knowledge information thus extracted; and an information analysis section for, after the knowledge information is stored, analyzing the electronic document based on the knowledge information in the storage section.

A system and method allows users to provide portions of scripts or scripts for retrieval of information from one or more web sites of one or more businesses by demonstrating operation of the one or more web sites and identifying locations of one or more fields on each web page of the one or more web sites, and the system and method stores the scripts and uses the scripts to retrieve information from such web site or web sites for any number of users. Different portions of different scripts may be used as a single script to retrieve information from a single web site. Scripts or portions of scripts may be repaired using information from previously working scripts or portions, the web site when the script or portion worked, and the web site when the script or portion did not work.

A system implementable on a computing device having a processor and a memory, including a visual design system to generate a single visual data structure based on a hierarchy of components; a database to store at least one visual data structure and an associated signature where the signature represents at least a semantic composition of the at least one visual data structure; a signature comparer to match a signature of the single visual data structure to an associated signature of at least one visual data structure stored in the database and to present multiple versions of alternate visual data structures for the hierarchy of components for selection by a user; and where the alternate visual data structures are visually different and semantically similar to each other.

A memory controller according to an embodiment includes a memory interface that reads out a received word from a non-volatile memory and a decoder that performs bounded distance decoding for the read received word. The decoder sets r.sub.m (r.sub.m is a natural number equal to or larger than 1) symbols of a plurality of symbols constituting the received word, as options of symbol positions at each of which an error is assumed, generates a test pattern in which m (m is a natural number equal to or larger than 1 and equal to or smaller than the r.sub.m) symbols of the r.sub.m symbols are objects of rewriting, generates test hard-decision values by rewriting each of hard-decision values of the m symbols that are objects of rewriting in the test pattern, among the symbols, and performs bounded distance decoding for the test hard-decision values.

Methods, devices and systems enhance compression and decompression of data blocks of data values by selecting the best suited compression method and device among two or a plurality of compression methods and devices, which are combined together and which said compression methods and devices compress effectively data values of particular data types; said best suited compression method and device is selected using as main selection criterion the dominating data type in a data block by predicting the data types within said data block.

A signal conversion device includes a first converting section configured to convert a clock signal input through a first signal line, a data signal input through a second signal line, and a control signal input through a third signal line, into pulse signals including a first pulse train and a second pulse train; and a transmitting section configured to transmit the first pulse train through a fourth signal line and the second pulse train through a fifth signal line, wherein the control signal is a signal that, through a level transition, causes a control target device to switch between an active state and an inactive state, and wherein the first converting section is configured to put successive pulses into at least one of the first pulse train and the second pulse train in response to the level transition of the control signal.

Methods and devices for coding point clouds using direct coding mode to code coordinates of a point within a sub-volume associated with a current node instead of a pattern of occupancy for child nodes. When direct coding is applied to two or more points in the sub-volume, the points are ordered based on one of their respective coordinate values in binary and pairwise coding of those coordinate values is carried out on a bit-by-bit basis starting from the most significant bit position. For example, the coordinate values relate to a direction in the Cartesian coordinate system, the location of the first point is represented by an x-direction coordinate value, a y-direction coordinate value and a z-direction coordinate value. The pairwise coding includes coding whether the bits are the same and, if so, coding the bit value.

Techniques for transforming character delimited values are presented herein. An input module is configured to read a set of character delimited values. A generation module is configured to generate a synchronization block for the set of values that includes a value selected from a byte size of the associated value and may be a flag representing a predetermined value. An output module is configured to output the synchronization block and the set of values to a binary data output stream for output in a device dependent byte order according to the respective byte sizes of the values in the set of values.

Embodiments of the invention may be used to implement a rate converter that includes: 6 channels in forward (audio) path, each channel having a 24-bit signal path per channel, an End-to-end SNR of 110 dB, all within the 20 Hz to 20 KHz bandwidth. Embodiment may also be used to implement a rate converter having: 2 channels in a reverse path, such as for voice signals, 16-bit signal path per channel, an End-to-end SNR of 93 dB, all within 20 Hz to 20 KHz bandwidth. The rate converter may include sample rates such as 8, 11.025, 12, 16, 22.05, 24, 32 44.1, 48, and 96 KHz. Further, rate converters according to embodiments may include a gated clock in low-power mode to conserve power.
