摘要： A bar code reader 10 includes a housing 20 including one or more transparent windows H, V and defining a housing interior region. As a target object is swiped or presented in relation to the transparent windows an image of the target object is captured. Cameras C1-C6 have an image capture sensor array with a global shutter is positioned within the housing interior region for capturing an image of a bar code within a camera field of view. All the cameras produce images in a sequential manner during an image frame time period. An image processing system has a processor for decoding a bar code carried by the target object. The processing system responds to signals from a light sensor to terminate object illumination when an adequate image exposure has transpired.

摘要： The exemplary bar code reader has an auto-focusing component positioned between a photo-detector array and an object having target indicia. The auto-focusing component has a lens system for focusing the target indicia at an imaging plane that generally co-incides with a plane of the photo-detector array. An electromagnetic coil actuator is coupled to an adjustable aperture such that activation of the coil actuator moves the adjustable aperture into and out of the imaging field of view to adjust a focusing on the target indicia. The autofocus component is fixed when the moveable aperture is within the field of view for focusing on objects close to the reader and when the aperture is removed, the autofocus is effective in imaging objects at a greater distance from the reader.

摘要： An optical code reading system and method are provided for reading and decoding an optical code. The system includes a plurality of light sources, a color image sensor, a processor and a decoder. Each light source produces a unique wavelength/color of light to illuminate the optical code, such as a direct mark optical code. The image sensor detects the reflected light from the optical code and generates an integrated multi-colored image. The processor separates the integrated image into individual color channels, where each color channel includes data representative of the imaged optical code in one color. The processor analyzes the contrast for each color channel and determines which color channel has the optimum contrast. The data corresponding to the color channel having the optimum contrast is then decoded by a decoder.

摘要： A CMOS Critical Voltage Transition Logic device which reduces propagation delays in a circuit by preconditioning the voltage outputs of each stage of the circuit to a critical voltage value which is between the logic high and logic low values for the circuit. The transition time to achieve either the high or low logic output states which is responsive to the input signal from the previous stage is reduced due to the preconditioning. Each stage is synchronously clocked in order to achieve the preconditioned state in each stage before processing the input signal for the previous stage. This unique switching characteristic greatly reduces the propagation delay in the circuit.
