  • Publication number: 20190271860
    Abstract: Eyewear for enhancing the contrast sensitivity of the human vision system through the use of lenses subdivided in areas of different light filtration properties arranged in specialized patterns, called multi-filters patterns, are provided. Of the multiple filtration areas, or filters, that compose each multi-filters patterns, one or more filters heavily reduces or totally block light arriving from some areas of the visual field of the eyes, while other filters lightly reduce or totally allow light from other areas of the same visual field. The resulting effect is to drive the auto-exposure function of the eye-brain vision system to adapt itself to areas of interest of the visual field thus improving contrast sensitivity and vision acuity in those areas while reducing or blocking light and glare from the rest of the visual field.

  • Publication number: 20060190750
    Abstract: A power management component in a computer system includes an imaging device operatively connected to a computer. When the computer has entered a low power state, the imaging device can continue to operate to detect motion in its field of view. When “enough” motion is detected, the imaging device can signal the computer in a manner as to transition the computer to a full power state. In another aspect of the present invention, the imaging device can determine that there has been insufficient motion for a predetermined period of time and initiate a transition of the computer to a low power state.

  • Patent number: 6995794
    Abstract: A low cost camera by implementing the major functions in host software is provided. This is accomplished by sending raw, digitized data from the camera directly to the host. The increased volume of raw data is handled by either an improved compression/decompression scheme using lossless compression, using lossy compression or using a shared bus with higher bandwidth. By moving such functions as color processing and scaling to the host, the pixel correction can also be moved to the host. This in turn allows the elimination of the frame buffer memory from the camera. Finally, the camera can use a low cost lens by implementing vignetting, distortion, gamma or aliasing correction with a correction value stored in a register of the camera for later access by the host to perform corrections.

  • Patent number: 6798446
    Abstract: A calibration system activates all or a majority of a display with the same value, such as with the same color. The camera is pointed at the display, but doesn't have to precisely pick up the whole display. The computer compares the pixel information received in the camera photosensor, and can store an appropriate correction factor. Not only does the user not have to precisely position the camera, jitter due to use hand movement is not a problem since this smoothes out the color information from the various pixels on the display, and actually improves the calibration. A target can be provided on the display to indicate if the user is properly pointing the camera at the display.

  • Patent number: 6704310
    Abstract: A method and apparatus for transmitting image data over a packet-based bus. The invention essentially supports multiple pipes within a single packet, thus utilizing a single set of pipe interface hardware. Each of the pipes within a packet has it's own header, and any particular packet can have 0, 1, 2 or more headers.

  • Patent number: 5956158
    Abstract: A scanner powered by the limited power available on a peripheral bus. In particular, the scanner can operate within the 2.2 watts provided over a USB connector. The scanner of the present invention uses a contact image sensor (CIS) which uses optics to distribute light from each light emitter to multiple pixel positions, preferably using a single LED for each color. An electric motor for driving the platen uses rare earth magnets to limit the power required. Instead of the traditional method of biasing the CIS scanner against the platen with a spring, the platen itself is spring-biased. The moveable spring biasing of a platen is possible because a worm drive motor is used allowing a helical thread on the worm drive to contact the platen gears as they move up and down as biased. Preferably, the helical thread of the worm gear has a single point of contact with a gear on the platen, further limiting the friction and allowing the platen to move up and down with respect to the stationary motor.

  • Patent number: 5522082
    Abstract: The present invention is a programmable data processing system and apparatus which operates as an independent microprocessor. The programmable data processing system of the present invention stores both general purpose and special purpose graphic instructions. The programmable data processing apparatus of the present invention has both types of instructions within its instruction set. This provision of a single processing apparatus for preforming both types of instructions enables a highly flexible solution to bit map graphics problems. This is because the program of the data processing apparatus may be altered to provide the most desirable graphics algorithm without loss of the general purpose calculation and program flow capability of a general purpose data processor. The data processor of the present invention may serve as a parallel processor for a host data processing system for primarily control of bit mapped graphics.

  • Patent number: 4256976
    Abstract: In an N-channel MOS integrated circuit operating in response to a major-major clock having four phases, .phi.1, .phi.2, .phi.3 and .phi.4, each of which has one, but only one, other phase which does not overlap therewith, an improved gate is disclosed wherein a first one of said phases samples an input signal for retention via a capacitive device, a second one of said phases is gated according to the state of the sample retained via the capacitive device, and a third one of said phases enhances the retention of the capacitive device.
