Systems And Methods For Processing Pricing Data

View page
US Patent:
8112335, Feb 7, 2012
Filed:
Mar 14, 2008
Appl. No.:
12/049067
Inventors:
David Isaac Tazartes - New York NY, US
Yukun Gou - Wayne PA, US
Liam Hudson - London, GB
Martin Zinkin - London, GB
Assignee:
Barclays Capital Inc. - New York NY
International Classification:
G06Q 40/00
US Classification:
705 35
Abstract:
Processing pricing data can be provided by receiving first data associating a first price source, a first market condition, and an instrument; receiving second data from at least one of a plurality of price sources, the second data comprising a first price quote for the instrument; determining that the at least one of the plurality of price sources matches the first price source; and generating a second price quote for the instrument based on the second data. Time data may be used for synchronizing the first data and the second data. The first price source may be changed to a second price source and/or the first market condition may be changed to a second market condition; and a third price quote generated for the instrument based on the associated second price source. Cached data may be used for processing the pricing data.

Keith Stuart Groves - London, GB
Jun Chen - Jersey City NJ, US
International Classification:
G06Q 40/00
G06F 9/44
US Classification:
705 7, 705 37
Abstract:
In at least one aspect, the invention comprises a computer-implemented method comprising: (a) electronically receiving a price request; (b) processing in a pipeline price information corresponding to said price request by applying a sequence of configurable rules to said price information; (c) temporarily withdrawing said price information from said pipeline while at least one of said configurable rules being applied is waiting for additional information; (d) inserting said price information into said pipeline after said additional information is received by said at least one of said configurable rules; (e) calculating a price based on said processed price information; and (f) electronically transmitting said price in response to said price request. Other aspects of the invention comprise related software and system implementations.

Method And System For Data Formatting

US Patent:
20090144381, Jun 4, 2009
Filed:
Nov 6, 2008
Appl. No.:
12/289924
Inventors:
Jie Li - Mountainside NJ, US
David Tazartes - New York NY, US
Yukun Gou - Wayne PA, US
Assignee:
Barclays Capital Inc. - New York NY
International Classification:
G06F 15/16
US Classification:
709206
Abstract:
A system includes a data store and a server in communication with the data store. The server includes formatting modules having a plurality of formatters, validation modules having a plurality of validators, and a streaming module. The server is configured to receive messages containing financial transaction data from one or more electronic communication networks or one or more client devices. The formatters are configured for each of the electronic communication networks or client devices and convert the messages into an internal format of the streaming system. The validation modules are configured to perform a validation check on the one or more formatted messages.

Pseudorandom Bit Sequence Generator

View page
US Patent:
63076314, Oct 23, 2001
Filed:
Jun 30, 2000
Appl. No.:
9/607471
Inventors:
Daniel A. Tazartes - West Hills CA
John G. Mark - Pasadena CA
David I. Tazartes - West Hollywood CA
Assignee:
Litton Systems Inc. - Woodland Hills CA
International Classification:
G01C 1972
US Classification:
356460
Abstract:
The invention is a method and apparatus for generating a primary pseudorandom bit sequence consisting of a plurality of contiguous P subsequences. Each P subsequence consists of a start sequence of predetermined length followed by a sequence of trailing bits. The method comprises three steps. The first step consists of deriving a feedback bit from each generating sequence in a P subsequence in accordance with a specified rule where a generating sequence is any sequence of contiguous bits in the P subsequence having the same length as the start sequence. The bit that follows a generating sequence is called the trailing bit for that generating sequence. The second step of the method consists of determining a sequence of one or more modifier bits to be used in modifying the P subsequence. The third step of the method consists of modifying the P subsequence utilizing the one or more modifier bits.

Pseudorandom-Bit-Sequence Modulated Fiber-Optic Gyro

View page
US Patent:
61151254, Sep 5, 2000
Filed:
Feb 22, 1999
Appl. No.:
9/255391
Inventors:
Daniel A. Tazartes - West Hills CA
John G. Mark - Pasadena CA
David I. Tazartes - West Hollywood CA
Assignee:
Litton Systems Inc. - Woodland Hills CA
International Classification:
G01C 1972
US Classification:
356350
Abstract:
The invention is a method and apparatus for determining the rotation of a medium through which a light beam propagates by modulating the light beam with a primary pseudorandom bit sequence consisting of a plurality of contiguous P subsequences. Each P subsequence consists of a start sequence of predetermined length followed by a sequence of trailing bits. The method comprises three steps. The first step consists of deriving a feedback bit from each generating sequence in a P subsequence in accordance with a specified rule where a generating sequence is any sequence of contiguous bits in the P subsequence having the same length as the start sequence. The bit that follows a generating sequence is called the trailing bit for that generating sequence. The second step of the method consists of determining a sequence of one or more modifier bits to be used in modifying the P subsequence. The third step of the method consists of modifying the P subsequence utilizing the one or more modifier bits.

Loop Controller For Fiber Optic Gyro With Distributed Data Processing

View page
US Patent:
56845898, Nov 4, 1997
Filed:
Aug 28, 1995
Appl. No.:
8/520217
Inventors:
John G. Mark - Pasadena CA
Daniel A. Tazartes - West Hills CA
David I. Tazartes - Beverly Hills CA
Assignee:
Litton Systems, Inc. - Woodland Hills CA
International Classification:
G01B 902
US Classification:
356350
Abstract:
A loop controller for a fiber optic gyroscope employs distributed data processing to compress numerous additional useful functions into each loop transit time. The architecture of the loop controller includes a field programmable gate array for generating variables of varying sign. In addition, the array acts to buffer the transmission of parameters between the gyro processor and an auxiliary processor. The auxiliary processor updates such parameters (which do not require updating every loop transit time) and a number of such parameters are multiplied by values generated by the array in operations performed by the gyro processor that replace what would otherwise require throughput intensive test and branch operations. The combination of the off-loading of selected variable and parameter generation and updating with programming of the gyro processor for parallel processing permits the loop controller to perform numerous useful operations not previously possible during a realistic loop transit time.

Pseudorandom Bit Sequence Generation

US Patent:
63172151, Nov 13, 2001
Filed:
Jul 7, 2000
Appl. No.:
9/611754
Inventors:
John G. Mark - Pasadena CA
Daniel A. Tazartes - West Hills CA
David I. Tazartes - Beverly Hills CA
Daniel P. Wiener - Simi Valley CA
Assignee:
Litton Systems Inc. - Woodland Hills CA
International Classification:
G01C 1972
US Classification:
356460
Abstract:
The invention is a method and apparatus for generating a pseudorandom sequence of bits. The method comprises the steps of (1) selecting a "0" or a "1" as the next bit of the modified pseudorandom bit sequence if one or more criteria are satisfied, the criteria being based on the measured properties of a plurality of prior bits of the modified pseudorandom bit sequence; otherwise: (2) selecting the next bit of an initial pseudorandom bit sequence as the next bit of the modified pseudorandom bit sequence, the next bit of the initial pseudorandom bit sequence being a function of one or more prior bits of the initial pseudorandom bit sequence.
