Abstract: A head-mounted display includes a varifocal actuation block and an optics block coupled to the varifocal actuation block. An anti-creep system located in the varifocal actuation block includes a plurality of anti-creep mechanisms that are configured to prevent bearing ball creep associated with bearing balls in the varifocal actuation block. The bearing balls are used to move a movable carriage that is coupled to a fixed carriage in the head-mounted display via the anti-creep mechanism. The anti-creep mechanisms prevent bearing ball creep associated with the bearing balls from occurring in the varifocal actuation block by limiting the movement in an angular direction of the bearing balls that are used to move the movable carriage in a first direction in the head-mounted display.

Abstract: A flexure based guidance system for precision motion control includes a base that is fixed in position, a carriage that can move relative to the base, an actuator provides the force to move the carriage relative to the base, and one or more flexures arrays that each comprise two or more leaf flexure elements. The actuator causes the carriage to move relative to the base, which causes the flexure elements in the flexure array to flex. The leaf flexure elements are thin, compliant and deform, bend, or deflect in a deterministic manner when mechanically stressed. In some embodiments, stiffeners can be added to the flexures. The guidance system can be integrated into a varifocal head mounted display (HMD) to adjust a location of one or moveable elements in an optical system of the HMD to control a location of an image plane.
