Abstract: An apparatus includes an image sensor, a linear actuator, a projector coupled to the linear actuator, and a controller coupled to the image sensor and to the linear actuator. The controller is configured to determine a location of an eye of a user based on image data from the image sensor. The controller is further configured to activate the linear actuator to drive the projector to a position associated with projecting to the eye at the location. The controller is further configured to initiate projection, via the projector, of an image depicting a view of a three-dimensional scene, the image selected based on the location.

Abstract: A method includes determining a first location, within a first viewing window, of a first eye of a user based on image data from an image sensor. The first viewing window corresponds to a first projector of a plurality of projectors. The method further includes determining a second location, within a second viewing window, of a second eye of the user based on the image data. The second viewing window corresponds to a second projector of the plurality of projectors. The method further includes initiating projection, via the first projector, of a first image depicting a first view of a three-dimensional scene. The first image is selected based on the first location. The method further includes initiating projection, via the second projector, of a second image depicting a second view of the three-dimensional scene. The second image is selected based on the second location.

Abstract: A method includes projecting, by a first projector, a first image to a first region, the first image having a first angular resolution and a first number of views. The method also includes projecting, by a second projector, a second image to a second region, the second image having a second angular resolution and a second number of views, where the second region is within the first region, the second angular resolution is greater than the first angular resolution, and the second number of views is greater than the first number of views.

Abstract: Methods and apparatus to render 3D content within a moveable region of a display screen. An example apparatus includes a projection system controller adapted to be coupled to a light source and to be optically coupled to a screen panel, the projection system controller configured to determine a location of a region within a viewing area of the screen panel to display content. The region is to be smaller than the viewing area. The location of the region is to move within the viewing area to track a motion path, the content including different stereoscopic views. The projection system controller configured to activate the light source to project light corresponding to the content toward the region. The screen panel includes a light redirecting surface to produce a 3D light field associated with the different stereoscopic views.

Abstract: A system having a color filter having first and second segments. The first and second segments allow respective first and second wavelengths to pass through to a spatial light modulator. The first and second segments also reflect second and first wavelengths, respectively. The reflected first and second wavelengths are recycled and directed towards the color filter.

Abstract: A device and method of forming the device that includes a first substrate having a cavity on a bottom surface of the first substrate and MEMS components formed on the first substrate and in the cavity; a second substrate having an upper surface; a first metal bond that extends around a perimeter of the cavity and forming a first connection between the bottom surface of first substrate and the upper surface of the second substrate; a second metal bond that extends around a perimeter of the first metal bond and spaced from the first metal bond, the second metal bond forming a second connection between the bottom surface of the first substrate and the upper surface of the second substrate; where the MEMS components are hermetically sealed between the first and second substrates. A getter agent can be between the first and second metal bonds.
