  • Publication number: 20180231779
    Abstract: A near-eye display system comprises first and second optical waveguides. The first optical waveguide is configured to receive a first image through a first entry aperture, to expand the first image along the first optical waveguide, and to release an expanded first image. Layered parallel to the first optical waveguide, the second optical waveguide is configured to receive a second image through a second entry aperture, to expand the second image along the second optical waveguide, and to release an expanded second image to overlap the expanded first image. The second entry aperture is offset from the first entry aperture along the second optical waveguide.

  • Patent number: 10048780
    Abstract: Architecture for managing clutch height in an optical navigational device such as a computer mouse. In one embodiment for a mouse, a feature can be molded into the bottom case that limits the clutch height by occluding the reflected light to the image sensor when the device is lifted from the tracking surface. Tracking is disabled when the clutch height threshold is exceeded, and re-enabled when the device is brought under the distance clutch height threshold. The device includes firmware controlled algorithm adjustments to one or more correlation parameters. User interfaces may also be employed to implement various aspects of the embodiments discussed herein.

  • Patent number: 10025355
    Abstract: In embodiments of a flexible display extendable assembly, an extendable assembly includes a slideable display guide integrated in a first housing part of an extendable electronic device. The extendable electronic device includes a flexible display that slide-engages into the first housing part of the extendable electronic device. The extendable assembly includes an extendable mechanism that is coupled in a second housing part of the extendable electronic device and to the slideable display guide. The first and second housing parts of the extendable electronic device slide-engage relative to each other. The extendable mechanism is implemented to extend as the first and second housing parts slide apart relative to each other, and also to retract as the first and second housing parts slide together relative to each other.

  • Publication number: 20180130391
    Abstract: An optical system comprises a linear illumination source configured to emit light, a first scanning stage configured to receive the light and to scan the light, and a second scanning stage. The linear illumination source is configured to generate light forming a vertical field of view based on the one or more output signals received from a controller modulating the one or more output signals comprising image data defining content. The first scanning stage redirects portions of the light to generate an output defining a horizontal field of view based on the one or more output signals of the controller. The first scanning device combines the vertical field of view and the horizontal field of view in the output light to create a two-dimensional light image of the content. The second scanning stage receives and directs the output of the first scanning stage toward a projected exit pupil.

  • Patent number: 9754415
    Abstract: Embodiments that relate to displaying an image via a display device worn on a head of a user are disclosed. In one example embodiment, an image is displayed at an initial registration position with respect to a user's eye. Composite motion data is received from one or more sensors, with the composite motion data comprising a head motion component and a relative motion component which is relative motion between the head and the display device. The composite motion data is filtered to remove the head motion component and yield the relative motion component. Using the relative motion component, the initial registration position of the image is adjusted to an adjusted registration position that compensates for the relative motion component. The image is then displayed at the adjusted registration position.

    Abstract: In embodiments of imaging structure color conversion, an imaging structure includes a silicon backplane with a driver pad array. An embedded light source is formed on the driver pad array in an emitter material layer, and the embedded light source emits light in a first color. A conductive material layer over the embedded light source forms a p-n junction between the emitter material layer and the conductive material layer. A color conversion layer can then convert a portion of the first color to at least a second color. Further, micro lens optics can be implemented to direct the light that is emitted through the color conversion layer.
