  • Patent number: 6659572
    Abstract: An emergency brake assist apparatus amplifies driver braking force upon imminent contact detection. A brake pedal, operated by the driver, exerts a pedal force upon a variable brake booster. A braking system is coupled to the variable brake booster that produces a variable brake booster force causing the braking system to exert a braking force proportional to the pedal force during normal operation. When a forward detection apparatus detects an imminent contact, a controller signals the variable brake booster to increase the variable brake booster force such that the braking system exerts an amplified braking force proportional to the pedal force.

  • Patent number: 6659578
    Abstract: A compact optical sensing system is used in hardcopy devices for scanning and/or printing images, for instance, using inkjet printing technology in desktop printing or in photographic printers appearing in grocery and variety stores. Several light emitting diodes (“LEDs”) illuminate a sheet of print media, and one or more photodiodes receive light reflected from the sheet. The photodiode generates signals in response to the light received, and the hardcopy device uses these signals to adjust printing parameters for optimal print quality. Using a chip-on-board process, the bare silicon die for each component is wire bonded directly to a printed circuit board assembly, allowing at least four LEDs (blue, green, red and soft-orange) to be grouped closely together in a space smaller than that occupied by a factory-made, single-packaged LED. A calibrating system uses a white target covered for cleanliness by a windowed door which is opened/closed by a printhead carriage.

  • Patent number: 6659600
    Abstract: The present invention provides an inkjet recording head cartridge and an inkjet recording apparatus that have a simple structure and high reliability. Since individual flow passages in which ink emission orifices are formed are communicated directly with a rectangular ink supply chamber, it is prevented that a bubble of such a size as to cause printing defects rises through an ink supply chamber and blocks the individual flow passages. Also, since ink heated within the ink supply chamber is moved upward to the ink tank chamber by convection and grows an air lump sealed beforehand, it is prevented that a bubble will grow in the ink supply chamber. Furthermore, by allocating a large cross-sectional area to the ink supply chamber, it is prevented that meniscus oscillation of the ink emission orifices is amplified by pressure oscillation caused by ink emission and causes a printing defect. Therefore, reliable printing can be performed with a simple construction.

  • Patent number: 6659611
    Abstract: A system and method for eye gaze tracking without calibrated cameras, direct measurements of specific users' eye geometries, or requiring the user to visually track a cursor traversing a known trajectory. The preferred embodiment includes two uncalibrated cameras imaging the user's eye and haying on-axis lighting. The cameras capture images of a test pattern in real space as reflected from the user's cornea, which is essentially a convex spherical mirror. The invention then extracts parameters required to define a mathematical mapping between real space and image space, including spherical and perspective transformations. The invention processes subsequent images of objects reflected from the user's eye through the inverse of the mathematical mapping to determine a gaze vector and a point of regard. Alternately, a single calibrated camera may be employed with means for estimating the eye-to-camera distance. A head-mounted embodiment that may include a laser pointer is also described.

  • Patent number: 6659613
    Abstract: Methods, systems, and media relating the display of scattering and/or absorption characteristics of an optical medium. For scattering measurements, a Hartmann-Shack calibration image of a measurement system is acquired to define a first plurality of point spread functions. A Hartmann-Shack test image of the medium is acquired to define a second plurality of point spread functions. A shift is determined between the test image and the calibration image. A point spread of each of the second plurality of point spread functions is measured, each of the second plurality of point spread functions including a component due to optical aberration of the medium and a component due to scatter. The component due to optical aberration is determined using the shift. The component due to optical aberration is deconvolved to determine the component due to scatter. A display of the local scattering characteristics is generated using the component due to scatter.

  • Patent number: 6659614
    Abstract: An optical signal, which is to become the subject of dispersion compensation, is split by optical combining/splitting unit 2, and each frequency component of the optical signal that is split is reflected by each reflective surface of reflective mirror 40 of reflective means 4 to apply a predetermined phase shift to the respective frequency components. Each reflected frequency component is then combined using optical combining/splitting unit 2, to give dispersion compensated optical signal. Furthermore, in regards to reflective means 4, which is used to apply phase shift to each frequency component of an optical signal, reflective mirror 40 is made a variable movable mirror by reflection position at each reflective surface, which reflects the frequency components, deforming the entire reflective surface. This allows dispersion that is created in an optical signal to be compensated with favorable controllability and high accuracy.
