The Twist-Base Mount couples a single-screw, substrate-penetrating element with an elastically-deformable, concave base element that, once installed, acts as a spring, exerting a downward force upon the substrate around its circumference. Because the base element is rigidly attached to the substrate-penetrating element, a force applied to the Mount parallel to the plane of the substrate is offset by the pressure of the perimeter of the base element against the substrate, resulting in additional strength. The Mount's single-screw, self-boring element allows quick and easy installation. The spring-like base-element permits 360-degree rotation of the Mount while maintaining uniform pressure against the substrate, thereby preserving strength regardless of rotational positioning. The mount remains economical in relation to mounts of similar strength and rotational adjustability due to its insert-molded construction.

A virtual visor system is disclosed that includes a visor having a plurality of independently operable pixels that are selectively operated with a variable opacity. A camera captures images of the face of a driver or other passenger and, based on the captured images, a controller operates the visor to automatically and selectively darken a limited portion thereof to block the sun or other illumination source from striking the eyes of the driver, while leaving the remainder of the visor transparent. The virtual visor system advantageously updates the optical state with blocker patterns that including padding in excess of what is strictly necessary to block the sunlight. This padding advantageously provides robustness against errors, allows for a more relaxed response time, and minimizes frequent small changes to the position of the blocker in the optical state of the visor.
