    摘要： The various embodiments include a near-eye display having a transmissive display and a diffractive micro-lens array. The transmissive display may be positioned relative to the diffractive micro-lens array so that the distance between the transmissive display and the diffractive micro-lens array is be approximately equal to focal length of the diffractive micro-lens array. The transmissive display may also be positioned relative to the diffractive micro-lens array so that a percentage of light emitted from the transmissive display is diffracted by the micro-lens array and collimated into focus on a retina of a human eye. The transmissive display may be further positioned relative to the diffractive micro-lens array so that light from a real world scene passes through transparent portions of the transmissive display and is diffracted by the micro-lens array out of focus of the human eye.

    摘要： In some embodiments, methods and systems are provided for assisting a user in determining a real-world distance. Hardware-based sensors (e.g., present in a mobile electronic device) may allow for a fast low-power determination of distances. In one embodiment, one or more telemetry-related sensors may be incorporated into a device. For example, data detected by a frequently-calibrated integrated accelerometer may be used to determine a tilt of the device. A device height may be estimated based on empirical data or based on a time difference between a signal (e.g., a sonar signal) emitted towards the ground and a corresponding detected signal. A triangulation technique may use the estimated tilt and height to estimate other real-world distances (e.g., from the device to an endpoint or between endpoints).

    摘要： A method of etching a glass substrate using an etchant that is reversibly activated to etch only in precise locations in which such etching is desired and is deactivated when outside of these locations. The method involves exposing a first side of the glass substrate to a mixture of chemical substances that includes a neutralized etchant that is photosensitive. The neutralized etchant is formed by reacting a neutralizer with an etchant. The method also includes transmitting light from a direction of a second side of the glass into the mixture of chemical substances. In response to exposure to this light, the etchant is reversibly released from a bond to the neutralizer to form the etchant on predetermined areas of the first side of the glass, wherein the predetermined areas are defined by the dimension of the light.

    摘要： Subdividing a color space is described for vector error diffusion which includes obtaining color coordinates for each primary color in the color space, and comparing the color coordinates to a threshold value for each coordinate plane of the color space. In response to the comparing, each primary color is grouped into a quadrant of the color space, wherein each quadrant is defined by the threshold value for each coordinate plane. In other aspects, a mapping a color to a closet primary color is described in a color space that includes a display determining color coordinates of the color and identifying a matching quadrant of a plurality of quadrants dividing the color space, wherein the determined color coordinates fall within the matching quadrant. A representative display device searches for the closest primary color within the matching quadrant and maps the color to the closest primary color found.
