Utility
Active correction of aberrations in optical systems
16 May 23
A method and apparatus for correcting aberrations over the entire field of view of an optical system, in which a first part of the apparatus applies different pre-compensating aberrations individually to different portions of the field of view, such that aberrations caused by a second part of the apparatus cancel the aberrations applied by the first part.

Utility
Head-mounted display with pivoting display
12 Jul 22
A wearable display apparatus has a support that mounts the display apparatus against the head of a viewer; a ball joint that is fitted within the support and coupled to a clamp that extends from the support; a slide that is translatable within the clamp in a first direction and that holds a display module for forming the display image; and a display coupled to the display module and rotatable in a first arc about a vertical axis that extends in a second direction that is orthogonal to the first direction and further rotatable in a second arc about a horizontal axis that is substantially orthogonal to the vertical axis.
