The images have color characteristics based on image information and the identified display condition. Differently colored images may be directed along associated portions of an optical path. The display device may be coupled to the apparatus and may be configured to display a color image formed of the differently colored images.

Abstract: A method of producing a display image comprises receiving image information representing an image to be displayed, producing an image formed of a plurality of images of different colors, and projecting the produced image along an optical path. The differently colored images have color intensities related to energy applied to a light source. A level of energy is applied to the light source during production of the image of one color that is different than the level of energy applied to the light source during production of the image of another color.

Abstract: A display system is configured to produce a color image formed of a plurality of differently colored images and may include at least one light source that directs light along an optical path, and at least one filter having a given optical filter characteristic. The display system may be selectively operable in a first state in which the optical path does not pass through a first filter during production of the plurality of differently colored images to form a color image having a first optical characteristic, and in a second state in which the optical path passes through the first filter during production of the plurality of differently colored images to form a color image having a second optical characteristic different than the first optical characteristic.

Abstract: A method and system for showing a presentation to a local and a remote audience is disclosed. The system includes a display device for presenting an information frame to the local audience. Coupled to the display device is a frame capture device for capturing an image of the information frame presented to the local audience. A transmission device, coupled to the display device, transmits the image of the information frame to a remote audience member.

Abstract: A system for displaying images on an active display is provided. The system includes an image information source configured to project optical image information, a plurality of display elements, and a plurality of receiving elements associated with the display elements, the plurality of receiving elements being configured to receive the image information from the image information source and further configured to activate the associated display elements according to the image information.

Abstract: A system for enhancing the quality of an image on a screen is provided. The system typically includes an illumination source configured to produce light and direct such light along an optical path, and a time-varying focus device disposed in the optical path and configured to periodically alter incident light to enhance the quality of the image on the screen.

Abstract: A lancer device that enables a user to draw blood from a patient and discard the used lancet without touching it. The device also has an adjustable tip for selecting the depth of stylet penetration into the patient and a triggering mechanism that utilizes a yoke latch and a leaf spring to discharge the lancet. The lancer also has a dampening feature to reduce vibrations when the lancet is moving.

Abstract: The present invention is directed to an apparatus and method for the stabilization and fastening of two pieces of tissue. A single device may be used to both stabilize and fasten the two pieces of tissue, or a separate stabilizing device may be used in conjunction with a fastening device. The stabilizing device may comprise a probe with vacuum ports and/or mechanical clamps disposed at the distal end to approximate the two pieces of tissue. After the pieces of tissue are stabilized, they are fastened together using sutures or clips. One exemplary embodiment of a suture-based fastener comprises a toggle and suture arrangement deployed by a needle, wherein the needle enters the front side of the tissue and exits the blind side. In a second exemplary embodiment, the suture-based fastener comprises a needle connected to a suture. The needle enters the blind side of the tissue and exits the front side. The suture is then tied in a knot to secure the pieces of tissue.

Abstract: Overall print quality is improved via a method whereby an actual image is printed, a virtual image is defined based on image data, and the actual and virtual images are compared to identify a printhead error pattern which may be used to correct subsequent printing errors. This typically is accomplished via a system which employs an optical device which views an actual image to produce optical data, and a controller which derives a virtual image from image data provided to the printhead. The controller then compares the actual and virtual images to identify an error pattern, and modifies subsequent image data to compensate for perceived errors.

Abstract: The present invention provides an image forming apparatus having a fiducial reference point sensor that individually monitors the position of first and second fiducial reference points on a moving print device that are in spaced relation to one another.
