Abstract: A display system can include a head-mounted display configured to project light to an eye of a user to display virtual image content at different amounts of divergence and collimation. The display system can include an inward-facing imaging system images the user's eye and processing electronics that are in communication with the inward-facing imaging system and that are configured to obtain an estimate of a center of rotation of the user's eye. The display system may render virtual image content with a render camera positioned at the determined position of the center of rotation of said eye.

Abstract: An optical imaging system with microlens array with integral structure includes a microlens array having a back surface for depositing sample material to be imaged and one or more microlenses on a front surface. At least one of the one or more microlenses are aligned to the deposited sample material. A plate is attached to the microlens array. A microscope objective is positioned proximate to the plurality of microlenses.

Abstract: A fluidic super resolution optical imaging system includes a microlens array chip comprising at least one lenslet on a first surface. An objective lens is positioned proximate to the at least one lenslet. A fluid jet is positioned proximate to a second surface of the microlens array that flows at least one of a fluid comprising a material to be imaged or a material that enables imaging of a second material through a focal area of the objective lens and the at least one lenslet.

Abstract: A method of tailoring an educational learning environment to a particular student may include receiving a selection of an educational game type from a plurality of educational game types and determining a learning activity. The method may also include determining a difficulty level for the learning activity and accessing a parameter set based on the learning activity and the difficulty level. The method may additionally include accessing, based on the parameter set, a set of functional instructions and a plurality of graphic objects. The method may further include creating an educational game based on the set of functional instructions, the plurality of graphic objects, the educational game type, the learning activity, and the difficulty level.
