Patent number: 11283496Abstract: A computer-implemented method, a computer program product, and a system include a processor(s) that produces a set of beamforming vectors, each vector produced based on a distinct set of parameters. To produce vector of the vectors, the processor(s) obtains, from receive antennas, data comprising a waveform comprising slots with boundaries, from a first collection window. The processor(s) determines the parameters (e.g., silent portion length and signal portion length) and determines which slots of the waveform contain signal operating instructions. The processor(s) aligns the slot boundaries, utilizing the data, based on determining which slots of the waveform contain signal operating instructions. The processor(s) extracts the signal portion and the silent portion, determines a covariance for each, and determines a vector and eigenvalue.Type: GrantFiled: December 19, 2018Date of Patent: March 22, 2022Assignee: PERSPECTA LABS INC.Inventors: Nicholas Chang, Eddie Fung, James Hodge

Patent number: 9787374Abstract: A system and method to optimize a multiple-input multiple-output signal processing RF communication system that includes obtaining, by a processor, at the receiver, during spatial processing, metrics from the channel stream. The metrics include a spatial correlation metric representing spatial coupling between multiplexed streams in the channel stream, a signal-to-noise power ratio metric representing propagation losses encountered by the signal, and a cross polarization discrimination metric representing whether polarization modes can be processed as independent groups. The processor obtains these metrics based on obtaining geometric information related to the receiver and the transmitter. Predictive methods may be employed to determine expectations for some metrics in advance. The method includes applying a policy with at least one objective of the system, and based on at least one metric and the policy, applying at least one adaptation to at least one of: the receiver or, the transmitter.Type: GrantFiled: July 16, 2014Date of Patent: October 10, 2017Assignee: Vencore Labs, Inc.Inventors: Ted K. Woodward, Tom Banwell, Eric Beck, Eddie Fung, John C. Koshy

Patent number: 8582607Abstract: The present disclosure relates to systems and methods for geographically-diverse redundant servers and the like interconnected via wavelength division multiplexed (WDM) systems with managed path differential delay of the WDM systems. The present disclosure provides transport systems and methods incorporating absolute time references, such as global positioning system (GPS) time references and/or the like, and selective buildout delays, such as first-in, first-out (FIFO) buildout delays and/or the like. In one exemplary embodiment, the transport systems and methods of the present invention are used in conjunction with the International Business Machine Corporation (IBM) Geographically-Dispersed Parallel Sysplex (GDPS) integrated, automated application and data availability solution to meet and/or exceed the associated 10 microseconds transmit/receive path differential delay requirement. Other comparable uses are also contemplated herein, as will be obvious to those of ordinary skill in the art.Type: GrantFiled: December 10, 2010Date of Patent: November 12, 2013Assignee: Ciena CorporationInventors: Steven A. Surek, Eddie Fung

Publication number: 20100307603Abstract: A method and apparatus for pressurizing a fillable-structure, wherein a space defined by the pump, an untraversed plunger, and a closure is a volume, Vt, and a stop to limit the travel of the plunger along the pump so a volume, Vb, remains within the space defined by the pump, the fully traversed plunger, and the closure. Traversal or manipulation of the plunger expresses gas from the pump to the Tillable-structure wherein the pressurization of the fillable-structure is limited by the ratio of Vt to Vb whereby the fillable-structure can not be pressurized beyond a pressure Pmax.Type: ApplicationFiled: June 1, 2010Publication date: December 9, 2010Applicant: The Marketing Store Worldwide, LPInventors: Ming Ki Gordon Au, Chuen Hung Eddie Fung, Kwok Leung NG, Kim Chuen B.

Patent number: 7734174Abstract: The present invention provides a colorless multiplexing system and method for detecting new optical channels at power levels below that which would cause data errors in existing traffic, and on top of background light, thus, overcoming a known risk inherent in colorless multiplexing—that a channel of the same wavelength as an existing channel is incorrectly added to the original working, traffic-carrying, channel's path.Type: GrantFiled: February 9, 2007Date of Patent: June 8, 2010Assignee: Ciena CorporationInventors: Douglas James Beckett, Brandon Collings, Lawrence J.

Patent number: 7570660Abstract: A network element for incorporating in nodes of a network that is a transparent, subwavelength networks. The element is configurable and adapted to support an arbitrary protocol, with protocol-specific monitoring features as well as protocol-independent add/drop capability. An arrangement that allows transmission of client signals with higher clock fidelity is achieved by developing a phases offset measure at an ingress node, communicating it to the egress node, and recovering the client's clock from the received data and from the received phase-offset information. The ability to recover the client's clock with high fidelity is enhanced by modified pointer processing in intermediate nodes of the network that the client's signal traverses. The pointer processing is modified to inject positive and negative justifications in excess of what is minimally necessary to insure proper transmission over a network that employs a protocol involving framing layer frames embedded in communication layer frames.Type: GrantFiled: October 1, 2004Date of Patent: August 4, 2009Assignee: CIENA CorporationInventors: Eddie Fung, Lawrence J.

Patent number: 6973602Abstract: Both link-level and path-level performance monitoring is obtained in any point of a multi-link network where transmitting points in the network are adapted to transmit codes only from a subset of the codes that receiving points in the network are adapted to receive, with one of the codes that transmitting points are adapted to transmit being chosen to represent an error-reporting code, and substituting, at monitoring points, any received code that is not one of the codes in the subset with the error-reporting code. By measuring the number of received codes that are in error, a link-level error measure is obtained, and by measuring the number of error-reporting codes, a path-level measure is obtained.Type: GrantFiled: September 5, 2002Date of Patent: December 6, 2005Assignee: CIENA CorporationInventors: Eddie Fung, Larry Nociolo, Martin Nuss, Jon Peticolas, Steve Surek, Ted Woodward
