  • Patent number: 8294729
    Abstract: Methods of performing stroke-to-raster video conversion having leading-edge error correction and/or falling-edge error correction are provided. Incoming data is pipelined before being written into a frame buffer. This allows each sample of data to be manipulated based on information obtained in samples that occur both before and after it. Highly accurate digital conversion of stroke video into a raster format having significantly reduced or eliminated noise and stray pixels from the video is therefore achieved.

  • Patent number: 7182566
    Abstract: A fastener, such as a nail, screw, etc., which possesses supplemental support and/or retention capability is provided. The fastener includes an elongated auxiliary member secured interiorly to, exteriorly to, or along the shaft of the fastener. The auxiliary member is secured to the shaft at two or more portions of the shaft. The auxiliary member provides the shaft with additional support strength and/or enables fastened materials to be retained upon breakage or shearing of the shaft as a result of, for example, heavy tensile or shearing loads. To facilitate breakage or shearing of the shaft, the shaft may be provided with a deformation, such as a notch or reduced circumference, at one or more desired locations such that the shaft breaks or shears at the deformation(s), thereby allowing the auxiliary member to function as the sole member which retains the fastened materials.

  • Patent number: 6832727
    Abstract: A display scanner includes an optical panel having a plurality of stacked optical waveguides. The waveguides define an inlet face at one end and a screen at an opposite end, with each waveguide having a core laminated between cladding. A projector projects a scan beam of light into the panel inlet face for transmission from the screen as a scan line to scan a barcode. A light sensor at the inlet face detects a return beam reflected from the barcode into the screen. A decoder decodes the return beam detected by the sensor for reading the barcode. In an exemplary embodiment, the optical panel also displays a visual image thereon.
