Abstract: The present invention provides a device and method for forming a ceramic-reinforced metal matrix composite (MMC) by follow-up ultrasonic-assisted direct laser deposition (DLD), and belongs to the technical field of additive manufacturing (AM). A positioning and clamping device is used to keep an ultrasonic impact gun to follow a coaxial powder feeding nozzle. During the DLD process of the ceramic-reinforced MMC, the cavitation, acoustic flow and mechanical and thermal effects of an ultrasound are used to intervene in a solidification behavior of a molten pool in real time, and a localized strengthening effect of an ultrasonic impact is used to adjust a stress in real time. Compared with a DLD forming method without follow-up ultrasound application, the method of the present invention effectively reduces the voids inside a workpiece, and ensures the consistency of a solidified structure and the evenness of stress distribution.

Abstract: An apparatus for filtering touches and disturbances of a container comprises a processing unit (PU) and computer-readable storage devices storing machine instructions. The PU obtains and sums together sensor values for a first sampling time from electrodes affixed to the container. The PU determines a difference between the sum for the first sampling time and a sum for a second sampling time, which is compared to a threshold representative of a change in capacitance due to a touch on the container. The PU determines whether the touch on the container has occurred at the first sampling time based on the comparison. If a touch occurred, the PU continues to obtain additional sensor values for additional sampling times and determine whether a touch on the container has occurred at the additional sampling times, until determining no touch occurred. The PU determines liquid level for the container after determining no touch occurred.
