摘要:
An asymmetric light emitting structure for producing polarized light that includes a light emitting layer having a plurality of light emitting species, wherein orientation of the light emitting species is uncontrolled. Receipt of the emitted light from the light emitting layer is accomplished via an asymmetric geometric element that also produces polarized light. Additionally, the asymmetric light emitting structure includes a means for excitation of the light emitting layer.
摘要:
A laser image projector includes a substrate; and a two dimensional array of individually addressable laser pixels formed on the substrate for emitting an imagewise beam of laser light perpendicular to the substrate, each of the laser pixels including an addressable organic light emitting diode (OLED) and an organic vertical cavity laser that is arranged to be pumped by the OLED.
摘要:
A laser emitting apparatus includes a substrate having on one side an incoherent light-emitting device having a light-emitting layer wherein an electric field is applied across the light-emitting layer to produce light which is transmitted out of the incoherent light-emitting device through an optically transparent layer into a vertical laser cavity structure disposed to receive light transmitted from the incoherent light-emitting device and produce laser light.
摘要:
A white-light laser integrated structure that includes a substrate; and one or more individually addressable laser light pixels formed on the substrate for emitting a white beam of laser light perpendicular to the substrate. Each of the one or more individually addressable laser light pixels include one or more organic light emitting diodes (OLEDs) and a plurality of organic vertical cavity lasers that are arranged to be optically pumped by the one or more OLEDs. The plurality of organic vertical cavity lasers emits differently colored light and the one or more individually addressable laser light pixels emit substantially white light when the differently colored light is combined.
摘要:
A computer system for selecting image products includes a display for displaying digital images, and for displaying representations of image products. Digital images are composited into the displayed representations to form digitally composited image product views. Programming controls displaying the composited image product views separately from the unselected representations. One or more of the displayed composited image product views are selected and assembled or fabricated.
摘要:
A method for displaying a collage of digital images on a display, receiving a selection for one of the digital images to be presented on a separate area of the display together with any associated multimedia, wherein one of the digital images has a portion overlapped by another digital image.
摘要:
A method of detecting UV-light-fluorescent indicia (14) with a camera (18) having a flash (20) and a sensor (22) includes mounting a visible-to-UV light conversion device (24) over the flash, activating the camera to initiate a visible-light flash exposure, converting visible light (17) from the flash to UV light (16) with the conversion device, and capturing a visible-light image of the indicia with the sensor on the camera.
摘要:
A plurality of server computers connected to computer network processes tasks that are unequally distributed among the server computers. A server sends a task-available message over the computer network to the remaining server computers to request assistance. The received task-available message is processed by some of the servers while others of the servers do not process the message because they are too busy. The servers that process the message respond by requesting a task from the message sending server.
摘要:
A method for authenticating an object that includes providing a label (12) with invisible indicia (14) printed with optically active material on a reflective substrate; providing a device that has a digital camera (18) having a light source (20), an image sensor (22), a first polarizing filter (24) having a first orientation, and a second polarizing filter (26) having a second orientation; illuminating the label with the light from the light source through the first polarizing filter; forming an image with the image sensor using reflected light from the label wherein the reflected light passes through the second polarizing filter prior to reaching the sensor; wherein the second polarizing filter makes the invisible indicia visible; and authenticating the object.
摘要:
Controlling a head-mounted display includes providing a head-mounted display, the head-mounted display includes a switchable viewing area that is switched between a transparent viewing state and an information viewing state. The transparent viewing state is transparent with respect to the viewing area and enables a user of the head-mounted display to view the scene outside the head-mounted display in the user's line of sight. The information viewing state is opaque with respect to the viewing area and displays information in the switchable viewing area visible to a user of the head-mounted display. An external environmental state detector provides an external stimulus notification in response to a detected change in the external environment and causes the viewing state to automatically switch in response to the external stimulus notification.
