Patent number: 7996454Abstract: A method and apparatus for performing complex mathematical calculations. The apparatus includes a multicore processor 10 where the cores 15 are connected 20 into a net with the processors on the periphery 15a primarily dedicated to input/output functions and distribution of tasks to the central processors 15b-h of the net. The central processors 15b-h perform calculations substantially simultaneously, far exceeding the speed of conventional processors. The method 100, which may be implemented by an instruction set to the processor nodes, informs the processor nodes how to divide the work and conduct the calculations. The method includes steps dividing the data into subsets 110 directing the subsets to predetermined nodes 115, performing the calculations 120 and outputting the results 125.Type: GrantFiled: November 16, 2007Date of Patent: August 9, 2011Assignee: VNS Portfolio LLCInventors: Paul Michael Ebert, Leslie O. Snively, Chiakeng (Jack) Wu

Publication number: 20100117880Abstract: An improvement in sampling a high frequency input analog signal and converting it to a digital output signal is disclosed. This is accomplished by using a multitude of analog-to-digital converters in conjunction with a distributed sampling system. This combination of multiple converters and a distributed sampling system allows use of conventional device processing, such as that of 0.18 micron silicon, and also provides accurate sampling of very high frequency input signals. The distributed sampling system provides multiple samplings of the input signal by using multiple ADCs for multiple samplings, wherein each sampling is sequentially offset a fixed amount of time from the most recent preceding sampling. Each ADC has a designated central processing unit (CPU) to obtain sufficient data transfer capabilities. The samplings from the multitude of ADCs are a series of sequential digital output values.Type: ApplicationFiled: August 10, 2009Publication date: May 13, 2010Inventors: Charles H. Moore, Leslie O. Snively, John Huie

Patent number: 7528756Abstract: An improvement in sampling a high frequency input analog signal and converting it to a digital output signal is accomplished by using a multitude of analog-to-digital converters in conjunction with a distributed sampling system. This combination of multiple converters and a distributed sampling system allows use of conventional device processing, such as that of 0.18 micron silicon, and also provides accurate sampling of very high frequency input signals. The distributed sampling system provides multiple samplings of the input signal by using a different ADC for each sampling, wherein each sampling is sequentially offset a certain amount of time from the most recent preceding sampling. The samplings from the multitude of ADCs are combined to form a single contiguous digital output signal. Types of distributed sampling systems include a multitude of elongated trace patterns interconnected in series, a specified permittivity material device, and a sequencer or multiplier.Type: GrantFiled: March 22, 2007Date of Patent: May 5, 2009Assignee: VNS Portfolio LLCInventors: Charles H.

Patent number: 4965586Abstract: A radio position determation and message transfer system is implemented using a pair of satellites in geostationary orbit for replaying interrogation and replay signals between a ground station and a user-carried transceiver. The user portion is calculated based on the arrival times of replay signals received at the ground station via the two satellites, the known transmission time of the interrogation signal from the ground station, and the user's elevation on the surface of the earth. The elevation is derived from a stored terrain map providing local terrain elevations at a plurality of points of the earth's surface. The stored terrain map allows accurate position fixed to be obtained for surface users regardless of the deviation of the local terrain from the spherical or ellipsoidal model of the earth's surface.Type: GrantFiled: October 31, 1988Date of Patent: October 23, 1990Assignee: Geostar CorporationInventors: Gerard K. O'Neill, Leslie O. Snively

Patent number: 4744083Abstract: A radio position determination and message transfer system is implemented using a number of satellites in geostationary orbit for relaying interrogation and reply signals between a ground station and a user-carried transceiver. Message information can be exchanged between a given user transceiver and the ground station, as well as between different user transceivers. The user transceiver is provided with means for monitoring the quality of the radio communication link between the transceiver and one or more of the satelites, based on errors detected in the received interrogation signals. The transmission of a reply signal by the transceiver is enabled only when the link quality is found to be acceptable. The reply signal may contain message information or may constitute a request for a position fix. In the latter case, the transceiver may be configured to await favorable link quality to more than one satellite before the reply signal is transmitted.Type: GrantFiled: September 14, 1984Date of Patent: May 10, 1988Assignee: Geostar CorporationInventors: Gerard K.
