Patent number: 11641126Abstract: A system for charging a battery includes an adapter, and a charger coupled to receive power from the adapter, and to provide a charging current to the battery. The charger includes a power stage with a charge pump to provide the charging current, and a feedback circuit to provide a feedback signal to the adapter. The power stage can be one of: an adjustable current source with voltage clamp, and an adjustable voltage source with current clamp. The charge pump can be implemented as a voltage divider, so that an input adapter current is multiplied by a pre-defined divider ratio to provide the charging current. The charge pump can be one of: single-phase; and multi-phase.Type: GrantFiled: July 18, 2018Date of Patent: May 2, 2023Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Zheren Lai, Jinrong Qian, Sai Bun Wong, Ryan Erik Lind, Alexander Lee McHale

Patent number: 11243966Abstract: Methods, systems, and devices supporting data storage are described. A database system may implement a hierarchical organization in which child data objects store hierarchical data for parent data objects. However, to support low latency time-series volume planning and analysis, the database system may additionally store a data object with a first set of data fields that includes object-specific data for the data object and a second set of data fields that includes hierarchical data (e.g., time-based hierarchical data organized into separate data fields for different time segments) for the data object. The database system may support both transactions and analytical queries using the data model. For example, the database system may receive a query indicating a time period for predictive analysis and may execute the query on the second set of data fields for the data object (e.g., without searching for child data objects storing the time-based hierarchical data).Type: GrantFiled: September 28, 2020Date of Patent: February 8, 2022Assignee: salesforce.com, inc.Inventor: Carey Kai-Bun Wong

Publication number: 20210231558Abstract: A method for analyzing a volatile liquid mixture is described. The method includes providing a sensor, and placing the sensor within a chamber. The mixture is stored in the chamber for a duration sufficient to achieve a series of dynamic non-equilibrium mass-transfer processes: (1) spreading and wetting of the analyte on at least a portion of the bottom-inside surface of the chamber from the source of the injection, (2) evaporation of at least a portion of the analyte liquid into a vaporized analyte, (3) convection and/or diffusion of the vaporized analyte through the chamber to the sensor, and (4) sorption of the vaporized analyte on the sensor. The sensor detects, over time, a plurality of non-equilibrium spectral responses, each corresponding to at least one compositional change in the analyte liquid. The method further includes machine learning algorithms to measure or predict the compositional change and/or presence of contaminants.Type: ApplicationFiled: May 16, 2019Publication date: July 29, 2021Inventors: Ida PAVLICHENKO, Elijah SHIRMAN, Sören BRANDT, Timothy Sheung Bun WONG, Austin TRIPP, Joanna AIZENBERG
