US Patent:

56920407, Nov 25, 1997

Filed:

Feb 29, 1996

Appl. No.:

8/608977

Inventors:

Richard David Greenblatt - Belmont MA

International Classification:

H04M 150

US Classification:

379350

Abstract:

A method of and apparatus for providing compatible universal identification telephone protocols by generating predetermined unique audio sequences recognizable by the telephone user as defining standardized Audio Icon information and distinct from and separated from one another and other telephonically transmitted signals; sending and receiving such generated audio sequences on a public switched telephone network having paths the parameters of which fall within predetermined specified training sets, including modem performance standards; and assuring recognition and correct identification of such audio sequences conveyed along such paths.

Appl. No.:

6/722837

Inventors:

Richard Greenblatt - Cambridge MA

Assignee:

Gigamos Systems, Inc. - Lowell MA

International Classification:

G06F 1200

US Classification:

364200

Abstract:

An address space, referred to herein as Moby space, may be defined having an address range greatly exceeding the direct addressing range of a particular computer, whereby each address in Moby space may be unique. Ranges of Moby space are swapped into and out of local memory space of the computer in question by processes referred to as reconciliation and dereconciliation. These processes are accomplished by maintaining in the computer, data structures which associate, typically on a per page or per section (multiple page) basis, each local page or section with its current Moby page or section. In addition to this address association and conversion, information being swapped must be scanned to separate the pointers from data and to appropriately convert pointers, but not data, as required during the swap. Achievement of aspects of the reconciliation and dereconciliation in separate hardware, particularly the maintenance of a running count of pointers to each page or section in local memory to identify which pages or sections may safely be swapped out, relieves the main processor of much of the overhead associated with these processes.

Appl. No.:

7/444836

Inventors:

Richard D. Greenblatt - Cambridge MA

Assignee:

Academy of Applied Science - Concord NH

International Classification:

H04J 312

US Classification:

3701104

Abstract:

A method and apparatus for telephone line multiplex channeling of toll-quality voice and modem-encoded digital data from telecommunication devices (FAX, computers, displays, printers, etc. ) involving variably sample-compression of digitally converted voice signals within successive time frames, and filling the resulting unoccupied time within each such frame with the modem-encoded digital data, and preferably with guard band signals separating the voice and modem-encoded digital data within each frame.

Filed:

Jun 30, 1994

Appl. No.:

8/269815

Inventors:

Richard David Greenblatt - Belmont MA

Assignee:

Academy of Applied Science - Concord NH

International Classification:

H04B 138
H04L 516

US Classification:

375222

Abstract:

A method and apparatus for "training" high speed telephonic modems to adjust or become corrected to obviate imperfections in the telephone channel or line, such as echoes, phase changes and other effects, while concurrently with voice communication on such simple telephone lines through sending test signals in unoccupied spaces of successive time frames created by compressing concurrent digital voice therein.

US Patent:

Filed:

Jun 21, 1989

Appl. No.:

7/369704

Inventors:

Richard D. Greenblatt - Cambridge MA

Assignee:

Academy of Applied Science - Concord NH

International Classification:

H04M 1106

US Classification:

370125

Abstract:

A novel method of and apparatus for voice communication and transparent, non-interfering, automatic digital data exchange between appropriately equipped telephone terminals having cooperative digital signal processing and visual display equipment, using special recognition signal protocol triggering signals and providing modem capability for FAX, printer, microprocessor, answer machines and the like for providing extended services using in-band signalling sensible by users and machines. Such method is useful both with ordinary telephone exchanges and ISDN type exchanges.
