Abstract: A head mounted display (HMD) comprises an eye tracking system configured to enable eye-tracking using light. The eye tracking system implements time-multiplexing by configuring a source assembly comprising a plurality of light sources to project at least a first light pattern towards the user's eye over a first time period, and a second light pattern towards the user's eye over a second time period in accordance with a set of emission instructions. A camera assembly is configured to capture images of the user's eye during the first and second time periods in accordance with a set of imaging instructions, the captured images containing one or more glints corresponding to reflections of the first or second light patterns on the cornea of the user's eye. The location of the glints may be used to determine a shape or orientation of the eye.

Abstract: A network media delivery system includes client devices and a host device. Each client device has a network interface, an engine for processing media data, and a media interface. The host device, which can be a computer, establishes network communication links with the client devices, which can be networked media stations, and sends media data to the client devices. The media data can be sent wirelessly as packets of media data transmitted at intervals to each client device. In one embodiment, the host device controls processing of media data such that processed media is delivered in a synchronized manner at each of the client devices. In another embodiment, the host device controls processing of media data such that processed media is delivered in a synchronized manner at the host device and at least one client device.

Abstract: An eyepiece waveguide for an augmented reality. The eyepiece waveguide can include a transparent substrate with an input coupler region, first and second orthogonal pupil expander (OPE) regions, and an exit pupil expander (EPE) region. The input coupler region can be positioned between the first and second OPE regions and can divide and re-direct an input light beam that is externally incident on the input coupler region into first and second guided light beams that propagate inside the substrate, with the first guided beam being directed toward the first OPE region and the second guided beam being directed toward the second OPE region. The first and second OPE regions can respectively divide the first and second guided beams into a plurality of replicated, spaced-apart beams. The EPE region can re-direct the replicated beams from both the first and second OPE regions such that they exit the substrate.

Abstract: An eye tracker characterization system comprising a scanning retinal imaging unit and a controller. The scanning retinal imaging unit characterizes eye tracking information determined by an eye tracking unit under test. The scanning retinal imaging unit includes a scanning optics assembly and a detector. The scanning optics assembly scans light in a first band across a retinal region of an eye of a user. The detector detects the scanned light reflected from the retinal region. The controller selects eye tracking information received from the eye tracking unit under test and corresponding eye tracking parameters received from the scanning retinal imaging unit. The controller calculates differences between the selected eye tracking information and the corresponding selected eye tracking parameters, and characterizes the selected eye tracking information based on the calculated differences.

Abstract: A disposable toilet seat cover/sanitizer includes a base layer and a barrier layer adjacent thereto, the disposable toilet seat cover/sanitizer having at least at least one portion thereof treated with a detergent and/or a disinfectant, the at least one treated portion is generally centrally arranged and is surrounded by a non-treated portion, the treated and non-treated portions are delimited by a perforation, the treated portion being detachable from the disposable toilet seat cover/sanitizer, thereby creating a central opening in the untreated portion.

Abstract: A wearable eye tracking system includes a pair of looping coils in a Helmholtz configuration and an additional looping coil. In one configuration, areas enclosed by the pair of looping coils in the Helmholtz configuration are in parallel with each other, while an area enclosed by the additional looping coil is offset from (i.e., not parallel with) the areas enclosed by the pair of looping coils. In this configuration, the pair of looping coils generates uniform magnetic fields between the two areas of the pair of looping coils in a first direction orthogonal to the areas of the pair of looping coils, and the additional looping coil generates additional non-uniform (or divergent) magnetic fields in a second direction transversal to the first direction.

Abstract: A virtual image generation system for use by an end user comprises a projection subsystem configured for generating a collimated light beam, and a display configured emitting light rays in response to the collimated light beam to display a pixel of an image frame to the end user. The pixel has a location encoded with angles of the emitted light rays. The virtual image generation system further comprises a sensing assembly configured for sensing at least one parameter indicative of at least one of the emitted light ray angles, and a control subsystem configured for generating image data defining a location of the pixel, and controlling an angle of the light beam relative to the display based on the defined location of the pixel and the sensed parameter(s).

Abstract: Embodiments relate to a head-mounted display including an eye tracking system. The eye tracking system includes a source assembly, a camera, and a controller. In some embodiments, the source assembly is a plurality of sources and are positioned to illuminate at least a peripheral area of a cornea of an eye. In some embodiments, the sources are masked to be a particular shape. The peripheral region is a location on the eye where the cornea transitions to the sclera. In some embodiments, the camera can detect a polarization of the reflected light, and uses polarization to disambiguate possible reflection locations. Similarly, time of flight may also be used to disambiguate potential reflection locations. The controller uses information from the detector to track positions of the user's eyes.

Abstract: Architectures are provided for selectively outputting light for forming images, the light having different wavelengths and being outputted with low levels of crosstalk. In some embodiments, light is incoupled into a waveguide and deflected to propagate in different directions, depending on wavelength. The incoupled light then outcoupled by outcoupling optical elements that outcouple light based on the direction of propagation of the light. In some other embodiments, color filters are between a waveguide and outcoupling elements. The color filters limit the wavelengths of light that interact with and are outcoupled by the outcoupling elements. In yet other embodiments, a different waveguide is provided for each range of wavelengths to be outputted. Incoupling optical elements selectively incouple light of the appropriate range of wavelengths into a corresponding waveguide, from which the light is outcoupled.
