Abstract: Systems and methods for closed-loop ultrasound imaging-based control are described herein. An example system includes an ultrasound transducer, and a controller operably coupled to the ultrasound transducer. The controller includes a processor and memory, the memory having computer-executable instructions stored thereon. The controller is configured to receive an ultrasound imaging signal associated with a subject's muscular activity from the ultrasound transducer; process the ultrasound imaging signal to obtain a feedback signal; and control a device interfacing with the subject based on the feedback signal.

Abstract: A new rice rinsing system for cleaning natural grown rice without having to get hands wet. The inventive device includes a cylindrical water bowl having an open upper end, a closed lower end and a cylindrical side wall therebetween. A cylindrical shaft extends upwardly from the closed lower end. A cylindrical rice holder is provided having an open upper end, a closed lower end and a cylindrical side wall therebetween. The closed lower end and the cylindrical side wall of the rice holder are perforated. A hollow cylindrical sleeve extends upwardly from the closed lower end of the rice holder. The cylindrical sleeve has an open lower end for receiving the cylindrical shaft of the water bowl therein when the rice holder is positioned within the water bowl. A water bowl lid is dimensioned for covering the open upper end of the water bowl. The water bowl lid has a centrally disposed aperture therethrough with a cylindrical collar extending upwardly therefrom.
