Patent number: 11777949Abstract: An illustrative computing system for a dynamic user access control management system classifies users and data resources according to their risk and importance by a user management engine with artificial intelligence, machine learning characteristics. The dynamic user access control management system analyzes the log files of data resources to measure system performance characteristics and user access behavior. This system monitors the device and network by which a data access request to a data resource is made. The dynamic user access control management system validates the leave status of a user initiating a data access request. The dynamic user access control management system automatically determines a user access level for a data resource through intelligent analysis of collected information and defers to a user's manager for an access level determination when the determination to grant an access level is outside of the knowledge base of the user management engine.Type: GrantFiled: June 6, 2022Date of Patent: October 3, 2023Assignee: Bank of America CorporationInventors: Vijaya Kumar Vegulla, Netla Hanumantha Reddy, Sandeep D'souza, Kumar Mahadeva Setty, Anil Kumar Venkata Kalyanam, Venugopala Rao Randhi

Patent number: 10353511Abstract: The present disclosure describes aspects of a capacitance-to-voltage modulation circuit. In some aspects, the circuit is used in touch sensing. In some aspects, a modulation circuit comprises a first pair of switches having one switch connected between a voltage source and a capacitor, and another switch connected between ground and the input of the circuit. The circuit also includes a second pair of switches having one switch connected between the voltage source and the input of the circuit, and another switch connected between ground and the capacitor. A third pair of the circuit's switches comprise one switch connected between the capacitor and an input of an analog-to-digital converter (ADC) and another switch connected between the input of the circuit and the input of the ADC. The third pair of switches may enable charge sharing of signals modulated by the first and second pairs of switches, a result of which can be used to sense touch input based on capacitance at the input of the circuit.Type: GrantFiled: September 20, 2016Date of Patent: July 16, 2019Assignee: QUALCOMM IncorporatedInventors: Bo-Ren Wang, Lennart Mathe, Sameer Wadhwa, Nathan Altman, Sandeep D'Souza

Patent number: 8682263Abstract: A programmable-current transmit continuous-time filter (TX-CTF) system can be included in a radio frequency (RF) transmitter. The input of the TX-CTF can receive a baseband transmission signal, and the output of the TX-CTF can be provided to an upconversion mixer for conversion to RF for transmission. The TX-CTF includes amplifier circuitry and passive circuitry that together define the filter parameters. The TX-CTF further includes programmable current circuitry that provides a programmable bias current to the amplifier circuitry. The TX-CTF system also includes control logic that receives one or more transmitter control signals and, in response, generates signals that control the bias current provided to the TX-CTF.Type: GrantFiled: July 18, 2011Date of Patent: March 25, 2014Assignee: Skyworks Solutions, Inc.Inventors: Sandeep D'Souza, Bipul Agarwal

Patent number: 6653679Abstract: An improved gate structure for a MOSFET device exhibits a reduced level of 1/f noise or “flicker noise”, while maintaining the control of boron penetration into the substrate of the MOSFET device. The gate structure for the MOSFET device includes a gate electrode and a gate oxide layer wherein nitrogen is selectively implanted into the gate oxide/device substrate interface prior to oxidation of the gate oxide layer. The nitrogen is selectively implanted so that the nitrogen is implanted into thin gate oxide regions and masked from thick gate oxide regions so that the benefits of controlling the boron penetration are realized while the 1/f noise is reduced due to the selective implantation of the nitrogen.Type: GrantFiled: December 11, 2001Date of Patent: November 25, 2003Assignee: Newport Fab, LLCInventors: Sandeep D'Souza, Li-Ming Hwang, Aniruddha Joshi, Suryanarayana Shivakumar Bhattacharya
