Abstract: An adapter assembly includes a knob housing, an outer tube, an end effector, an articulation link, and a sensor assembly. The end effector is movable from a first position where the end effector is aligned with a longitudinal axis defined by the outer tube, to a second position where the end effector is disposed at an angle relative to the longitudinal axis. Longitudinal translation of the articulation link relative to the outer tube causes the end effector to move from its first position to its second position. The sensor assembly includes a first portion disposed in mechanical cooperation with the articulation link, and a second portion disposed at least partially within the outer tube. The sensor assembly is configured to determine an actual amount of articulation of the end effector based on a distance the articulation link move longitudinally relative to the outer tube.

Abstract: Systems and methods of defending against stack-based cybersecurity attacks that exploit vulnerabilities in buffer overflows. The embodiments disclosed herein propose applying a randomized modification to the original size of the stack frames of functions of a program. By applying a randomized modification to the length of the stack frame, e.g., randomly increasing the length of the allocated stack frame memory, it becomes harder (if not impossible) for the attacker to guess or estimate the memory location where the return address of a function is stored, regardless of the attacker's knowledge of the length of the stack frame. Multiple implementations, e.g., randomizations at transform time, load time, and run time are discussed herein.
