Abstract: An eye tracking system can include eye-tracking camera(s) configured to obtain images of the eye at different exposure times or different frame rates. For example, longer exposure images of the eye taken at a longer exposure time can show iris or pupil features, and shorter exposure, glint images can show peaks of glints reflected from the eye. The shorter exposure glint images may be taken at a higher frame rate than the longer exposure images for more accurate gaze prediction. The shorter exposure glint images can be analyzed to provide glint locations to subpixel accuracy. The longer exposure images can be analyzed for pupil center and/or center of rotation. The eye tracking system can predict gaze direction, which can be used for foveated rendering by a wearable display system. In some instances, the eye-tracking system may estimate the location of a partially or totally occluded glint.

Abstract: An eye tracking system can include an eye-tracking camera configured to obtain images of the eye at different exposure times or different frame rates. For example, longer exposure images of the eye taken at a longer exposure time can show iris or pupil features, and shorter exposure, glint images can show peaks of glints reflected from the cornea. The shorter exposure glint images may be taken at a higher frame rate (than the longer exposure images) for accurate gaze prediction. The shorter exposure glint images can be analyzed to provide glint locations to subpixel accuracy. The longer exposure images can be analyzed for pupil center or center of rotation. The eye tracking system can predict future gaze direction, which can be used for foveated rendering by a wearable display system. In some instances, the eye-tracking system may estimate the location of a partially or totally occluded glint.

Abstract: The electrical cover comprises a friction-held electrical cover for a recessed light fixture. Embodiments of the electrical cover described herein provide flexible finish material covers that guard recessed “can” light fixtures from paint, spackling, and other foreign materials. The frictionally-held finish material covers utilize specifically shaped features on the surfaces, such as negative draft, that contact the electrical components to increase the hold on the electrical device. Some of the shaped features of the frictionally-held covers also help minimize stress in the cover. Features are also molded into the parts to assist and strengthen the cover once installed, and thus protect against the intrusion of finish material behind the cover.

Abstract: The electrical cover is a flexible, friction-held electrical cover that guards outlets from finish materials such as paint, spackling, and other foreign materials. The frictionally-held finish material electrical covers utilize specifically shaped features on the surfaces, such as negative draft, that contact the electrical components to increase the hold on the electrical device. Some of the shaped features of the frictionally-held covers also help minimize stress in the cover. The electrical covers are shaped with an arched rear surface that assists in minimizing edge warping when the electrical cover is positioned against the wall surface. Features are also molded into the parts to assist and strengthen the cover flatness once installed, and thus protect against the intrusion of finish material behind the cover.

Abstract: An electrical cover including a pair of opposed rim sides having an amount of curvature between the pair of opposed rim sides, a switch guard medially disposed in the electrical cover, the switch guard including a pair of opposed grasp wall sides convex in relation to the interior space of the switch guard, and a pair of aperture elements disposed adjacent the switch guard.

Abstract: Systems disclosed herein provide objects that are capable of altering a configuration of touch points in contact with a surface of a touch-sensitive system. In one embodiment, an object includes an outer member, an intermediate member, and an inner member. The outer member has an opening between a top surface and a bottom surface. The intermediate member has an opening between a top surface and a bottom surface, where the intermediate member fits within the opening of the outer member. The inner member fits within the opening of the intermediate member and has a bottom surface. The bottom surface of each of the members includes a touch point. A contact with the surface for each touch point is coplanar when the members are fit together. Further, the configuration of touch points in contact with the surface defines an identifier for the object to the touch-sensitive system.
