G06T 7/80
G06T 7/90

Abstract:

A method for characterizing a digital color camera includes, for each of three primary colors used in a field sequential color virtual image, determining a conversion model for each color using RGB values and the color-measurement values. For each primary color, the method includes illuminating a display device using an input light beam of a primary color having spectral properties representative of a light beam in a virtual image in a wearable device. The method includes capturing, with the digital color camera, an image of the display device, and determining, from the image, RGB values for each primary color. The method includes capturing, with a color-measurement device, a color-measurement value associated with each corresponding primary color at the display device, thereby acquiring a color-measurement value in an absolute color space. A conversion model for each color is determined using RGB values and the color-measurement values.

Abstract:

A system for conducting the identification and quantification of micro-organisms, e.g., bacteria in urine samples which includes: 1) several disposable cartridges for holding four disposable components including a centrifuge tube, a pipette tip having a 1 ml volume, a second pipette tip having a 0.5 ml volume, and an optical cup or cuvette; 2) a sample processor for receiving the disposable cartridges and processing the urine samples including transferring the processed urine sample to the optical cups; and 3) an optical analyzer for receiving the disposable cartridges and configured to analyze the type and quantity of micro-organisms in the urine sample. The disposable cartridges with their components including the optical cups or cuvettes are used in the sample processor, and the optical cups or cuvettes containing the processed urine samples are used in the optical analyzer for identifying and quantifying the type of micro-organism existing in the processed urine samples.

G02B 6/12

Abstract:

Techniques are described for using confinement structures and/or pattern gratings to reduce or prevent the wicking of sealant polymer (e.g., glue) into the optically active areas of a multi-layered optical assembly. A multi-layered optical structure may include multiple layers of substrate imprinted with waveguide grating patterns. The multiple layers may be secured using an edge adhesive, such as a resin, epoxy, glue, and so forth. A confinement structure such as an edge pattern may be imprinted along the edge of each layer to control and confine the capillary flow of the edge adhesive and prevent the edge adhesive from wicking into the functional waveguide grating patterns of the layers. Moreover, the edge adhesive may be carbon doped or otherwise blackened to reduce the reflection of light off the edge back into the interior of the layer, thus improving the optical function of the assembly.
