Patent number: 11948562Abstract: Described herein is a system for predictive feature analysis to precompute and store data required to respond to a user input in advance of receiving the user input. To determine when to precompute the data, the system uses a prediction model to predict user interactions and when to expect the user input. The system predicts that a user input is about to be received, and starts to process certain data to determine feature data and stores the data in a cache. When the user input is received, the system retrieves the data from the cache for further processing to respond to the user input.Type: GrantFiled: December 11, 2019Date of Patent: April 2, 2024Assignee: Amazon Technologies, Inc.Inventors: William Evan Welbourne, Min Hao Chen, Jennifer Liwen Chen

Patent number: 11949320Abstract: A device includes a current mirror, a switch, first and second current paths, first and second buffers, a variable resistor, a temperature-sensing circuit, and a controller. The first current path is coupled between the current mirror's input and the switch. The switch switches between ground and a transistor based on a control signal. The second current path is coupled between a first current mirror output and ground. The first buffer is coupled to a second current mirror output. The second buffer is coupled to the variable resistor, which is coupled to the first buffer. The temperature-sensing circuit provides a device temperature to the controller, which is coupled to a first buffer output and determines a first adjustment to the first and second current paths and a second adjustment to the variable resistor based on the device temperature.Type: GrantFiled: February 23, 2022Date of Patent: April 2, 2024Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Vishnuvardhan Reddy Jaladanki, Preetam Charan Anand Tadeparthy, Scott Ragona, Rengang Chen, Evan Michael Reutzel, Bhaskar Ramachandran
