Publication number: 20240080421Abstract: An apparatus includes a first camera configured to capture a first image being displayed, a second camera configured to capture a second image being displayed, and a processor configured to generate a pair-wise homography transform for the first camera and the second camera, and map, based on the pair-wise homography transform, the second image from a second frame of reference of the second camera to a first frame of reference of the first camera. The processor is further configured to determine a first corrected quadrilateral for the first image and a second corrected quadrilateral for the second image in the first frame of reference, and project, based on the pair-wise homography transform, the second corrected quadrilateral from the first frame of reference to the second frame of reference. The quadrilaterals are then processed to warp respective images for geometric correction before projecting the images by respective projectors.Type: ApplicationFiled: June 30, 2023Publication date: March 7, 2024Inventors: Shivam SRIVASTAVA, Jaime Rene DE LA CRUZ VAZQUEZ, Jeffrey Matthew KEMPF

Patent number: 11881867Abstract: In described examples, a circuit includes a calibration engine. The calibration engine generates multiple input codes. A digital to analog converter (DAC) is coupled to the calibration engine, and generates a first calibration signal in response to a first input code of the multiple input codes. An analog to digital converter (ADC) is coupled to the DAC, and generates multiple raw codes responsive to the first calibration signal. A storage circuit is coupled to the ADC and stores a first output code corresponding to the first input code. The first output code is obtained using the multiple raw codes generated by the ADC.Type: GrantFiled: September 7, 2021Date of Patent: January 23, 2024Assignee: Texas Instruments IncorporatedInventors: Narasimhan Rajagopal, Eeshan Miglani, Chirag Chandrahas Shetty, Neeraj Shrivastava, Shagun Dusad, Srinivas Kumar Reddy Naru, Nithin Gopinath, Charls Babu, Shivam Srivastava, Viswanathan Nagarajan, Jagannathan Venkataraman, Harshit Moondra, Prasanth K, Visvesvaraya Appala Pentakota

Publication number: 20220058465Abstract: In an approach for forecasting in multivariate irregularly sampled time series, a processor receives time series data having one or more missing values. A processor determines, from the time series data, non-missing values present in the time series data. A processor determines, from the time series data, zero or more mask values for the time series data. A processor determines time interval values. A processor inputs the one or more missing values, the non-missing values, the zero or more mask values, and the time interval values into a recurrent neural network. A processor determines a predicted value for the one or more missing values.Type: ApplicationFiled: August 24, 2020Publication date: February 24, 2022Inventors: Prithviraj Sen, Berthold Reinwald, Shivam Srivastava

Publication number: 20180247296Abstract: The present document describes a payment system that processes transactions originating from mobile phones, cellular devices, Web browsers, or other mobile devices. A customer initiates a transaction by sending a payment request via SMS, HTTPS, or other network protocol. The payment request includes an amount to be paid and a phone number associated with a recipient. The payment system confirms the identity of the customer, and identifies the recipient based at least in part on the phone number. The payment system supports the fulfillment of payment requests with various combinations of account balances, credit accounts, discounts, and loyalty points. The payment system also provides various merchant features such as ticket vending, automatic discovery of payees and payers, management of merchant terminals, and payroll processing.Type: ApplicationFiled: October 27, 2016Publication date: August 30, 2018Inventors: Tun Tun Win, Manickam Subramanian, Abhishek Modi, Shivam Srivastava
