Patent number: 11968265Abstract: Systems and methods for asynchronous API-driven external application services for blockchain are provided. The blockchain may store profile data that permits asynchronous communications and data sharing among a plurality of trusted users, and an application server layer may act as a gateway to a blockchain system to selectively provide limited access to external application services to operate upon the blockchain data.Type: GrantFiled: June 7, 2023Date of Patent: April 23, 2024Assignee: The Travelers Indemnity CompanyInventors: William K. Devine, Emma J. Scopino, Robert W. Jenkins, Vinod Srinivasan

Patent number: 7453922Abstract: The invention provides methods and apparatus for multiple user detection (MUD) processing that have application, for example, in improving the capacity CDMA and other wireless base stations. One aspect of the invention provides a multiprocessor, multiuser detection system for detecting user transmitted symbols in CDMA short-code spectrum waveforms. A first processing element generates a matrix (hereinafter, “gamma matrix”) that represents a correlation between a short-code associated with one user and those associated with one or more other users. A set of second processing elements generates, e.g., from the gamma matrix, a matrix (hereinafter, “R-matrix”) that represents cross-correlations among user waveforms based on their amplitudes and time lags. A third procesing element produces estimates of the user transmitted symbols as a function of the R-matrix.Type: GrantFiled: March 14, 2002Date of Patent: November 18, 2008Assignee: Mercury Computer Systems, Inc.Inventors: John H. Oates, Steven R. Imperiali, Alden J. Fuchs, Kathleen J. Jacques, Jonathan E. Greene, William J. Jenkins, Frank P. Lauginiger, David E. Majchrzak, Paul E. Cantrell, Mirza Cifric, Ian N.

Patent number: 7110437Abstract: The invention provides methods and apparatus for multiple user detection (MUD) processing that have application, for example, in improving the capacity CDMA and other wireless base stations. One aspect of the invention provides a digital signal processor (“DSP”) that processes user waveforms. The DSP has an associated memory and an associated direct memory access (“DMA”) controller that controls access to that memory. A programmable logic device (“PLD”) is coupled to the DMA controller and configures it to move data relating to user waveform characteristics from the memory to a buffer external to the DSP.Type: GrantFiled: March 14, 2002Date of Patent: September 19, 2006Assignee: Mercury Computer Systems, Inc.Inventors: John H.
