Abstract: A method, system and non-transitory computer readable medium for multi-stage communication between an autonomous vehicle and a road user. The autonomous vehicle uses vehicle external cameras, a LiDAR sensors and radar sensors to image the surrounding environment. Image processing circuitry is used to develop a view of the surrounding environment from the sensed images and the view is combined with stored map data. Road users, which may include pedestrians, bicyclists, motorcyclists and non-autonomous vehicles are identified on the view and it is determined whether the movement of the road user will intersect the trajectory of the autonomous vehicle. The autonomous vehicle performs a vehicle behavior modification as a first stage signal to alert the road user of its intent. If the road user does not react to the first stage signal, the autonomous vehicle activates additional external lighting as a second stage signal to alert the road user.

Abstract: A variable stiffening device that include a first electrode structure and a second electrode structure. The first electrode structure includes an electrode extension that extends into a cavity defined between an electrode of the first electrode structure and an opposing electrode of the second electrode structure. The first and second electrode structures may be arranged in a load-bearing state by applying a voltage thereto to electrostatically attract the electrode to the opposing electrode to press the electrode extension within the cavity. Friction between the electrode extension and engaging surfaces defining the cavity prevent the electrode extension from slipping within the cavity, thereby maintaining a structural relationship among the components of the first and second electrode structures in response to an application of a load to the variable stiffening device.
