Inventors:

Leonid D. Levin - Newton MA

International Classification:

B41J 530
G06F 1538

US Classification:

364419

Abstract:

An abbreviated text entering system is described which provides a plurality of files each of which includes a full text word and a corresponding abbreviated word. In each of the files the abbreviated word is formed using a different rule, and at least one file is provided for words of five or more characters, a different file is provided for words including one of a plurality of predefined prefixes, a further file is provided for words including one or more predefined suffixes, and another file is provided for words which include one of a plurality of predefined prefixes and one of a plurality of predefined suffixes.

US Classification:

364419

Abstract:

A method and apparatus for rapidly entering text into a computing machine is described. An operator may enter text in abbreviated form using several simple rules to predict which abbreviated word forms will be correctly recognized. In the event of conflicts (where one abbreviated word matches more than one full text work), the operator selects the preferred resolution either on an individual or global basis.

Abstract:

Systems and methods are provided for performing neurometric evaluation of Quantitative Electro Encephalogram (QEEG) data, derived from Dry Sensor technology, as opposed to the use of any types of conventional paste/gel and silver/silver chloride sensors. The individuals who would be helped by these screening procedures are identified.
