  • Patent number: 6760071
    Abstract: A method of transferring charges for a CCD image-sensing device. First, the K register elements (every k register elements) are defined as a charge-combining portion, thereby providing m charge-combining portions. The y image-sensing elements sense incident light energy to generate y charge packets proportional to the light intensity. Then, the y charge packets are transferred in a parallel manner to the CCD shift register. The charge packets coupled to each of the m charge-combining portions are accumulated into one specific register element when the k register elements have coupled the charge packets from the image-sensing elements, thereby generating m adding charge packets in the m charge-combining portions. Finally, each of the adding charge packets is serially delivered to the output of the CCD shift register, converting the adding charge packets into proportional voltage levels.

  • Patent number: 6760075
    Abstract: Method and apparatus are provided for seamless integration of multiple video projectors. In addition to edge blending, projection artifacts in dark or black image regions caused by residual grays from non-perfect projector black levels are reduced. Overlapped and non-overlapped areas of the image are defined and then the minimum black level of the video signal in non-overlapped areas is boosted without affecting the bright portion of the video signal in order to create uniform black level. The bright portion of the image is then smoothed in the overlapped area with seamless edge blending techniques. The resultant projected image may be passed through a neutral density filter to lower the base black level of the now uniform overlap and non-overlap black regions. The image may also pass through a physical mask which is hard edged or graded and aligned to less than the overall overlap region and that when used, smooths the edge of transition between the non-overlapped and overlapped regions.

  • Patent number: 6760078
    Abstract: In a radio receiver for digital television signals a digital filter supplies the in-phase synchrodyning circuitry a shaped spectral response to the digitized I-F signal. The amplitude-versus-frequency response of the digital filter rolls off through the carrier region, so that there is substantially no boost of the amplitudes of lower frequency components of the baseband symbol coding recovered by the in-phase synchrodyning circuitry, with respect to the amplitudes of higher frequency components of the baseband symbol coding such circuitry recovers. When the DTV receiver is initially tuned to a channel, the adaptation of the adaptive channel equalizer proceeds without having initially to compensate for the low-end boost.

  • Patent number: 6760093
    Abstract: A liquid droplet containing thermosetting or ultraviolet curing adhesive material is jetted out to either of a transfer member (5) or an image receiving member (11) so as to correspond to a shape of an image so that a latent image is formed. The transfer member (5) and the image receiving member (11) are brought into close contact with each other so that the latent image is interposed between the transfer member (5) and the image receiving member (11). Then, heat or ultraviolet rays are applied for curing the adhesive material so that a transfer material formed on the transfer member (5) is fixed to the image receiving member (11) through the cured adhesive material. Then, the transfer member (5) and the image receiving member (11) are separated from each other so that only the fixed transfer material is transferred to the image receiving member (11). As a result, a required image is formed.

  • Patent number: 6760101
    Abstract: Light emitted from an illumination optical system is guided to a photomask where a pattern is formed of an optical member including a light transmission pattern as a diffraction grating pattern, in which a light transmission part and a opaque part are repeated in a finite period and a periphery of the light transmission pattern is shielded by a opaque area, such that a plurality of ratios are given between the light transmission part and the opaque part. Diffraction light, which has passed through the photomask, is irradiated on a projection optical system, thereby to transfer a pattern reflecting an intensity distribution of the diffraction light to a wafer. A change of transmittance depending on a light path of the projection optical system is measured, based on a pattern image of the diffraction light transferred to the wafer. Pattern transfer is carried out in a non-conjugate state.

  • Patent number: 6760102
    Abstract: To detect yarn defects such as protruding filaments, broken filaments, ringers, fuzzballs, stripbacks and the like, a yarn sheet 9 traveling in a plane is scanned by light beams from at least two light barriers 10, 11. When a yarn defect interrupts the light beam of a light barrier, a detector pulse is triggered, appropriately amplified and transformed and sent to evaluating means 22. Such a detector pulse is triggered each time a yarn defect passes through a light barrier, so that the travel time or time difference T1,2 between the trip times of a yarn defect through the two light barriers can be determined by the evaluating means. Since the yarn sheet 9 passes through the light barriers at a constant velocity v, the travel times for the various individual ends from one light barrier to the next will differ and therefore can be used to determine the distance S normal to the yarn traveling direction of the yarn defect to the point of intersection of the light beams of the two light barriers.
