Abstract: An improved system and method of performing capacitance measurements that provides a fast digital response and a reduced output error. The capacitance measurement system includes a circuit configuration that has a variable capacitor and at least one reference capacitor connected to one another at a common node, which in turn is connected to the input of an analog-to-digital converter. The circuit configuration further includes an array of switches coupled between the variable and reference capacitors and the supply voltage, a reference voltage, and ground, respectively. The switched variable and reference capacitors are employed in conjunction with the A-to-D converter to perform, at the common node, a plurality of direct voltage measurements for use in generating an expression defining the capacitance of the variable capacitor.

Abstract: A character string correction system corrects a spelling error in a character string input through the keyboard, OCT, etc. An error pattern representing frequent occurrences of errors is preliminarily set and stored in the memory, etc. A processor reads an input character string character by character, and compares the read character with the error pattern. If the input character string matches an error pattern, it is assumed that an error exists. The input character is replaced with one of the alternative characters. Using the input character string or the character string corrected with an alternative character, a dictionary (TRIE table) is searched. If a corresponding word is detected in the dictionary, the word is output as one of the recognition results.

Abstract: A retrieving unit retrieves an entry of a dictionary which corresponds to an input character string while comparing input characters, one by one, with entries of TRIE tables stored in a dictionary storing unit. When a character of the input character string does not coincide with any of the entries in the currently-used TRIE table, a skipping unit locates a next effective pseudo-syllable border in the input character string to find candidates of those TRIE tables which correspond to the effective pseudo-syllable border. The retrieving unit retrieves a character string consisting of those characters which follow the pseudo-syllable border thus located, while using the candidates of these TRIE tables, and retrieves an entry in the dictionary which corresponds to the input character string to thereby output it as a recognized word.
