  • Patent number: 10624809
    Abstract: The present disclosure provides a method for controlling an exoskeleton robot. The method comprises checking that a first signal is triggered by a first button, checking a tilt angle after the first signal is triggered, setting an action based on the tilt angle, and executing the action to move the exoskeleton robot. The first signal indicates to change the exoskeleton robot from a standing posture to another posture, and the tilt angle is a leaning-forward angle of a waist assembly of the exoskeleton robot relative to a line vertical to ground. The method utilizes the tilt angle to judge the intent of the user, and thus can simplify the controlling buttons to one or two buttons. Further, the controlling method also monitors the tilt angle to choose a suitable action.

  • Publication number: 20200020856
    Abstract: The present disclosure relates to a resistive random access memory (RRAM) device architecture, that includes a thin single layer of a conductive etch-stop layer between a lower metal interconnect and a bottom electrode of an RRAM cell. The conductive etch-stop layer provides simplicity in structure and the etch-selectivity of this layer provides protection to the underlying layers. The conductive etch stop layer can be etched using a dry or wet etch to land on the lower metal interconnect. In instances where the lower metal interconnect is copper, etching the conductive etch stop layer to expose the copper does not produce as much non-volatile copper etching by-products as in traditional methods. Compared to traditional methods, some embodiments of the disclosed techniques reduce the number of mask step and also reduce chemical mechanical polishing during the formation of the bottom electrode.
