Latest Patents

Williams' latest patents include a multi-focus optical reader with masked or apodized lens. This invention provides a method and apparatus for reading bar codes or other images while minimizing the reliance on self-generated illumination. The design features a handheld unit equipped with an efficient optical collection system, which includes an aperture with a high aspect ratio and/or multi-focal lenses. An optically transmissive spacer is affixed to the front of the unit, allowing it to collect ambient light at close range. Additionally, a diffuser may be utilized to reflect ambient light, enhancing illumination for close-range reading. The device incorporates a masked CCD detector with rectangular pixels, which is linked to an adaptive exposure circuit that prevents saturation at high illumination levels. Furthermore, a correlated double sampling circuit is connected to the adaptive exposure circuit, effectively rejecting common mode noise and enabling operation in lower light conditions. This circuit is also linked to a signal processor that employs a derivative-based technique for edge detection, allowing a decoder to interpret encoded information from the image.
