Abstract: A method for touchless gesture recognition is provided. The method includes transmitting ultrasonic signals via a speaker. The method includes generating ultrasonic signals. The method includes receiving the reflected ultrasonic signals from an object via two or more microphones. The method includes computing a frequency shift according to the reflected ultrasonic signals. The method includes identifying a gesture that corresponds to a movement of the object according to the frequency shift. The method includes performing a function that corresponds to the gesture.

Abstract: A computing system may include an initial design space engine and an active region adaptation engine. The initial design space engine may be configured to identify a design domain for which to optimize a topology based on an objective function and determine an active region. The active region adaptation engine may be configured to iteratively adapt the active region until an optimization ending criterion is satisfied. Iterative adaptation of the active region may include expanding the design domain to include branch design elements, performing finite element analysis (FEA) on the expanded design domain, and determining an adapted active region by activating some of the branch design elements based on an active sensitivity threshold and deactivating some of the active design element based on design variable value changes.
