  • Patent number: 7883208
    Abstract: A system for providing an intraocular lens includes a processor and a computer readable memory. The computer readable memory is configured to communicate with the processor, the memory having stored therein at least one of: one or more ocular dimensions, and at least one predetermined refractive outcome. The memory further includes a sequence of instructions which, when executed by the processor, cause the processor to select an intraocular lens, select a power of an intraocular lens, or provide an intraocular lens. The sequence of instructions includes determining one or more dimensions of an eye. The instructions also include calculating, based on a mathematical relationship, a distance from an apex of a cornea of the eye to an apex or plane of the intraocular lens after insertion into the eye. The instructions further calculating an optical power of the intraocular lens suitable for providing a predetermined refractive outcome.

  • Patent number: 7883210
    Abstract: Apparatus for photographing the anterior segment and retina of the eye through the use of a camera attachment designed to snap-fit onto an ophthalmoscope without permanently altering the ophthalmoscope itself. The plastic attachment houses a digital camera with video and still photo capabilities. A button on the camera allows for snapshots to be taken. The camera is connected to a laptop or stationary computer via a USB cable. The camera, which utilizes software for photo and video management, relays views to a computer and monitor, projecting the same view on the screen as a practitioner would see when using the ophthalmoscope traditionally.

  • Patent number: 7883211
    Abstract: A subjective vision testing system is used for visual function tests for examinees. The subjective vision testing system is provided with an optometric apparatus which selectively sets optical elements in front of both eyes of an examinee, an optotype presenting apparatus for displaying optotypes to the examinee, and a controller. The optotype presenting apparatus, based on a command signal for implementation of a binocular balance test, displays optotypes used for binocular balance tests. The optometric apparatus, based on a command signal for implementation of a binocular balance test, sets a first prism in front of the examinee's right eye and a second prism in front of the examinee's left eye. The second prism has a base direction vertically opposite to the first prism and the same prism power as the first prism.

  • Patent number: 7883212
    Abstract: An image projection apparatus (100) comprises a projector (106), a frame (108), and a partially transparent screen (110). The frame (108) retains the screen (110) under tension, such that the screen (110) is inclined at an angle with respect to a plane of emission of light from the projector (106). The screen (110) has a front surface arranged such that light emitted from the projector (106) is reflected therefrom. The projector (106) projects an image such that light forming the image impinges upon the screen (11) such that a virtual image is created from light reflected from the screen (110), the virtual image appearing to be located behind the screen (110).

  • Patent number: 7883213
    Abstract: A liquid crystal projection system (70) includes a light source (50) for emitting a white light beam of three primary colors, a polarizer (51) for polarizing the white light beam, a separating mirror (52), first and second reflecting mirrors (53, 54), first and second polarization separators (56, 57), a half-wave plate (55), a color separator (58), image modulation devices (60R, 60G, 60B) and a projection lens (59). The separating mirror splits the incident polarized white light beam into two sets of polarized light beams, a monochromatic light beam and a bichromatic light beam that are respectively output to the first and second reflecting mirrors (53, 54). The polarized monochromatic light beam is reflected by the first reflecting mirror, transformed to a light beam with reversed polarization by the half-wave plate, and output to the first polarization separator.

  • Patent number: 7883214
    Abstract: A lightweight, compact image projection module has a laser package having a common exit port, and a plurality of lasers mounted in the package and operative for emitting a plurality of laser beams of different wavelengths through the common exit port. An optical assembly focuses the laser beams exiting the common exit port, and includes a common focusing lens through which the laser beams pass along respective paths that are in angular misalignment. An optical corrector element in at least one of the paths corrects the misalignment to produce aligned beams. A scanner sweeps the aligned beams in a pattern of scan lines, each scan line having a number of pixels. A controller causes selected pixels to be illuminated, and rendered visible, by the aligned beams to produce the image.

  • Patent number: 7883215
    Abstract: One embodiment of the invention discloses projector circuit boards comprising an image receiving terminal, a central processing unit, a motor driving module, a DMD and a DMD control module. The image receiving terminal receives an image signal and transmits the received image signal to the central processing unit. The central processing unit processes the received image signal. The motor driving module drives a motor on the basis of the processed image signal to rotate a color wheel to generate a colored beam. The DMD, comprising a plurality of micro-mirrors, is used in reflecting the colored beam, transforming the colored beam into an image beam, and transmitting the image beam to a projection lens to project an image. The rotation angles of the micro-mirrors are controlled by the DMD control module coupled between the central processing unit and the DMD. The projector circuit board is perpendicular to a light path of the projection lens.

  • Patent number: 7883219
    Abstract: System and method for thin projection display systems. An embodiment comprises a light source, an array of light modulators optically coupled to the light source, a lensed mirror optically coupled to the array, and a controller electronically coupled to the array and to the light source. The array produces images on a display plane by modulating light from the light source based on image data and the controller provides light commands to the light source and load image data into the array. The lensed mirror reflects modulated light from the array onto the display plane, the lensed mirror comprising a refractive portion and a reflective portion. The refractive portion of the lensed mirror helps to increase the light bending capability to help reduce the overall thickness of a projection display system.
