Patent number: 11520651Abstract: A tool may identify and revert changes that caused network hardware components or hardware servers to malfunction. The tool builds and maintains a graph that represents the hardware components and servers in the system and their dependencies. When a change is made to the system, links and weights in the graph are adjusted to account for the changes. When a component or server is reported as malfunctioning, the tool traverses the graph to locate the changes that are the most likely root causes of the malfunction. The tool may then revert the change to resolve the malfunction.Type: GrantFiled: August 11, 2021Date of Patent: December 6, 2022Assignee: Bank of America CorporationInventors: Surina Puri, Asif Ahmad Bala, Arjun Thimmareddy

Patent number: 11082056Abstract: A stage, suitable for use in an analog to digital converter or a digital to analog converter, can have a plurality of slices that can be operated together to form a composite output. The stage can have reduced thermal noise, while each slice on its own has sufficiently small capacitance to respond quickly to changes in digital codes applied to the slice. This feature allows a fast conversion to be achieved without loss of noise performance.Type: GrantFiled: November 22, 2019Date of Patent: August 3, 2021Assignee: ANALOG DEVICES INTERNATIONAL UNLIMITED COMPANYInventors: Rares Bodnar, Asif Ahmad, Christopher Peter Hurrell

Patent number: 10707889Abstract: An electronic circuit comprises multiple analog-to-digital converter (ADC) circuits and control logic circuitry. The control logic circuitry advances the multiple ADC circuits through multiple time-interleaved conversions that include time-interleaved acquisition phases, conversion phases, and tracking phases. An acquisition phase of a first ADC circuit samples the analog signal, a conversion phase of the first ADC circuit converts the sampled analog signal to a digital value, and the control logic circuitry is configured to update the first ADC circuit with most recent A/D conversion information by a different ADC circuit during a tracking phase of the first ADC circuit before the acquisition phase of the first ADC circuit.Type: GrantFiled: May 13, 2019Date of Patent: July 7, 2020Assignee: Analog Devices International Unlimited CompanyInventors: Rares Andrei Bodnar, Christopher Peter Hurrell, Asif Ahmad

Patent number: 10511316Abstract: A stage, suitable for use in and analog to digital converter or a digital to analog converter, comprises a plurality of slices. The slices can be operated together to form a composite output having reduced thermal noise, while each slice on its own has sufficiently small capacitance to respond quickly to changes in digital codes applied to the slice. This allows a fast conversion to be achieved without loss of noise performance. The slices can be sub-divided to reduce scaling mismatch between the most significant bit and the least significant bit. A shuffling scheme is implemented that allows shuffling to occur between the sub-sections of the slices without needing to implement a massively complex shuffler.Type: GrantFiled: August 2, 2018Date of Patent: December 17, 2019Assignee: ANALOG DEVICES GLOBAL UNLIMITED COMPANYInventors: Rares Bodnar, Roberto S.

Method of applying a dither, and analog to digital converter operating in accordance with the method
Patent number: 10505561Abstract: A dither is an uncorrelated signal, usually pseudo-random noise injected into the input of an ADC such that a given input value of the wanted signal becomes spread over a plurality of codes. This reduces the effect of DNL and also smooths the integral non-linearity (INL) response of the ADC. The advantages of introducing dither could be obtained without having to perturb the signal input to the ADC. This avoids the introduction of additional components in the ADC. The dither can be applied to the components used to form a residue of the ADC stage within a pipelined converter. For example, a dither can be applied solely to a DAC part or different dithers can be applied to a ADC and DAC parts respectively. This allows greater flexibility of linearization of the ADC response and the formation of an analog residue by the DAC.Type: GrantFiled: August 2, 2018Date of Patent: December 10, 2019Assignee: Analog Devices Global Unlimited CompanyInventors: Rares Bodnar, Asif Ahmad, Christopher Peter Hurrell -
Patent number: 10476821Abstract: Disclosed herein is a secure messaging engagement hub for structuring of unstructured electronic messages. The secure messaging engagement hub has a natural language processor that structures an unstructured electronic message. The natural language processor structures the unstructured electronic message by using a lexical parser to parse free text within the unstructured electronic message. The natural language processor also may tokenize the parsed free text into tokens representing components of the parsed free text. Message component n-grams are generated based on the tokens representing the components of the parsed free text. The tokens are coded with various metadata tags based on an analysis of the tokens. The metadata tags indicate message components of the tokens. And a structured electronic message corresponding to the unstructured electronic message is generated, the structured electronic message comprising the tokens and the metadata tags.Type: GrantFiled: May 27, 2015Date of Patent: November 12, 2019Assignee: ATOS DIGITAL HEALTH SOLUTIONS, INC.Inventors: Asif Ahmad, David Raju Manne, Pranam Ben
