Patent number: 11941689Abstract: A system and a method for accepting a payment on an application is provided. The method is implemented by a processor. The processor receives login information from a client to activate a banking application; selects quick accept entry points associated with the client's business banking demand deposit account (DDA) based on determining that the client is eligible for the quick accept entry points in response to the login information; sets up a payment receiving option for receiving a payment via the banking application; causes the banking application to receive transaction amount data corresponding to a transaction between the client and a customer; causes the banking application to process the transaction amount data; and automatically updates the DDA to reflect receipt of the transaction amount data.Type: GrantFiled: December 7, 2020Date of Patent: March 26, 2024Assignee: JPMORGAN CHASE BANK, N.A.Inventors: Jatin Garg, Jasbir Banga, Nirmal Kumar, Ted Hellman, Mizan Miah, Ryan S Yoder, Mohamed Abdullah, Angela Govila

Patent number: 10810990Abstract: An active noise cancellation (ANC) system including a selectable decimation rate decimator that receives an oversampled digital input and has an input that selects the decimation rate, a filter that receives an output of the decimator, and a selectable interpolation rate interpolator that receives an output of the filter and has an input that selects the interpolation rate. The selectable decimation rate decimator and the selectable interpolation rate interpolator operate to provide a selectable sample rate for the filter based on the selected decimation and interpolation rates. The filter may be an anti-noise filter, feedback filter, and/or a filter that models an acoustic transfer function of the ANC system. Rate selection may be static, or dynamically controlled based on battery or ambient noise level. A ratio of the decimation rate and the interpolation rate is fixed independent of the dynamically controlled decimation and interpolation rates.Type: GrantFiled: January 30, 2019Date of Patent: October 20, 2020Assignee: Cirrus Logic, Inc.Inventors: Gabriel Vogel, Jeffrey Alderson, Ryan A.
