Abstract: Methods, systems, computer-readable media, and apparatuses for gesture detection using ultrasound beamforming are presented. In some embodiments, a method for gesture detection utilizing ultrasound beamforming includes projecting an ultrasound wave parallel to a surface, wherein the ultrasound wave is projected utilizing ultrasound beamforming. The method further includes receiving an ultrasound echo from an object in contact with the surface. The method additionally includes interpreting a gesture based at least in part on the received ultrasound echo.

Abstract: A modular circuit emulation system includes a global clock generator that generates a plurality of clock signals. A plurality of emulation boards each include at least one programmable circuit and a clock buffer. The clock buffer generates at least one synchronized clock signal for clocking the programmable circuit or circuits, based on at least one of the plurality of global clock signals.
