Abstract:
In order to provide a home user with cost-effective PC processing capability, the home user is provided with a terminal which has only sufficient processing capability to communicate with a service provider over a network. Any processing and program execution is performed, in response to requests from the home user's terminal, by the service provider and the results are returned to the terminal. In addition to the processing capability, data is stored in the service provider. Because the processing and data storage is performed by the service provider, changes to the programs and/or hardware can the confined to the processing resources of the service provider. In addition, the service provider can be provided with virus and hacking protection, protection that will then not be necessary for the home user's terminal. In this manner, the home user can be charged for only the facilities and software that are actually used, while having available the full capability of a personal computer without the initial cost of a home computer, the on-going cost of maintenance, and the cost of upgrading hardware and software. The communication link can be a secure link.
Abstract:
In an optical image acquisition and information transmission system, the system components can be fabricated, according to a first implementation, in a stack positioned on a circuit board. According to a second implementation, the system components are fabricated on a single substrate using the same semiconductor processes for each component. Both implementations result in better performance parameters. These systems are particularly useful as control devices wherein information resulting from processing the acquired image rather than the image itself is transmitted.
Abstract:
A memory circuit (14) having features specifically adapted to permit the memory circuit (14) to serve as a video frame memory is disclosed. The memory circuit (14) contains a dynamic random access memory array (24) with buffers (18, 20) on input and output data ports (22) thereof to permit asynchronous read, write and refresh accesses to the memory array (24). The memory circuit (14) is accessed both serially and randomly. An address generator (28) contains an address buffer register (36) which stores a random access address and an address sequencer (40) which provides a stream of addresses to the memory array (24). An initial address for the stream of addresses is the random access address stored in the address buffer register (36).

Abstract:
A text-to-speech synthesis system receives digital code representative of characters from a local or remote source, and converts those character codes into speech. A set of allophone rules is contained in a memory and each incoming character set is matched with the proper character set to describe the sound of that particular character set. A microcontroller is dedicated to the comparison procedure which provides allophonic code when a match is made. The allophonic code is provided to a speech producing system which has a system microcontroller for controlling the retrieval, from a read-only memory, of digital signals representative of the individual allophone parameters. The addresses at which such allophone parameters are located are directly related to the allophonic code. A dedicated microcontroller concatenates the digital signals representative of the allophone parameters, including code indicating stress and intonation patterns for the allophones. An LPC speech synthesizer receives the digital signals and provides analog signals corresponding thereto to a loud speaker to produce speech-like sounds with stress and intonation.
Abstract:
An electronic apparatus for translation from a host language to a non-host language in which the individual word is evaluated as to its contextual meaning. The sequence of words, typically a sentence, within the host language, which is communicated to the electronic apparatus is translated, through a recognition device into a series of recognized words. These recognized words are further refined through analysis of their contextual meaning within the sequence (sentence) so as to differentiate between words of similar pronunciation and between homonyms. The present invention permits the direct entry, from voice, to a translator to a foreign language or alternatively to control language for use with an electronic or electromechanical apparatus.
Abstract:
A pulse width modulated digital-to-analog converter for utilization in low voltage, integrated circuit speech synthesis circuitry. A digitally programmable shift register is utilized to generate a pulse, which is generally related to the magnitude of a digital signal. A programmable delay circuit provides finer resolution by converting the least significant digital bits of data into pulse width information of shorter duration than the minimum pulse width generated by the controllable shift register. Pulse width information generated by the shift register and delay circuit is applied to the bases of two crossconnected transistors to drive a speaker or voice coil.
