Patent number: 11618158Abstract: The present invention relates to a new pneumatic-actuated multifunctional doming actuator. The doming actuator can be used as a doming actuator, which can maintain machine/robotic operation on vertical surfaces without falling. The doming actuators exhibit rapid switchable adhesion/deadhesion on target surfaces upon pressurizing/depressurizing the embedded spiral pneumatic channels. The present invention also relates to novel load-carrying and climbing soft robots using the doming actuators. The soft robots are operable on a wide range of horizontal and vertical surfaces including dry, wet, slippery, smooth, and semi-smooth surfaces. In addition, the doming actuators can be used as a driving actuator for swimming soft robotics and as an actuator for soft grippers.Type: GrantFiled: June 18, 2018Date of Patent: April 4, 2023Assignee: Temple University-Of The Commonwealth System of Higher EducationInventors: Yichao Tang, Jie Yin

Patent number: 10833585Abstract: Described herein is a technology for implementing a scalable SCIB regulator for high conversion step down application. Particularly, the SCIB is configured to include stacked input switch circuits with parallel-connected output switch circuits. The input switch circuits are stacked with or without DC shift switch circuits in between. Furthermore, the input voltage is stepped down to a biasing voltage by input switch circuits and then is regulated to one or more output voltages having one or more independent and predetermined values by output switch circuits. The input switch circuits, output switch circuits and DC shift switch circuits can be modified for scalable power capability and ease of control and manufacturing.Type: GrantFiled: November 30, 2018Date of Patent: November 10, 2020Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Yichao Tang, Sombuddha Chakraborty

Patent number: 10696182Abstract: An integrated and isolated onboard charger for plug-in electric vehicles, includes an ac-dc converter and a dual-output dc-dc resonant converter, for both HV traction batteries and LV loads. In addition, the integrated and isolated onboard charger may be configured as unidirectional or bidirectional, and is capable of delivering power from HV traction batteries to the grid for vehicle-to-grid (V2G) applications. To increase the power density of the converter, the dual-output DC-DC resonant converter may combine magnetic components of resonant networks into a single three-winding electromagnetically integrated transformer (EMIT). The resonant converter may be configured as a half-bridge topology with split capacitors as the resonant network components to further reduce the size of converter. The integrated charger may be configured for various operating modes, including grid to vehicle (G2V), vehicle to grid (V2G) and high voltage to low voltage, HV-to-LV (H2L) charging.Type: GrantFiled: April 2, 2018Date of Patent: June 30, 2020Assignee: University of Maryland, College ParkInventors: Alireza Khaligh, Yichao Tang
