摘要： A method of determining the lower limit of decoding resolution in a digital imaging-based bar code symbol reader. A software-based optical design program is used to generate the composite DOF chart of image formation optics employed in the digital imaging-based bar code symbol reader. The modulation transfer function (MTF) of the object image is used to determine the smallest mil size code that can be decoded, at a given object distance, to produce an optical performance curve. The program calculates the size of the field of view (FOV) of a single sensor pixel, when projected through the image formation optics and out into object space. For both the 1.4 and 1.6 sampling limit pixel rules, the calculated FOV values are plotted on the same axes as the optical performance curve. Using graphical solution techniques, the sampling limit line of choice determines the lower limit of the decoding resolution in the imaging-based bar code symbol reader.

摘要： A multi-mode laser-based bar code symbol reading device having a hand-supportable housing with a light transmission aperture, wherethrough visible light can exit and enter the hand-supportable housing. A laser scanning engine, disposed within the hand-supportable housing, is controlled to selectively operate in either an omni-directional reading mode or a uni-directional bar code reading mode. In the omni-directional bar code reading mode, the laser scanning engine projects pattern through the light transmission aperture, an omni-directional laser scanning pattern producing multiple laser scanning lines with substantially uniform spatial and temporal intensity characteristics at any given scanning plane parallel to the light transmission aperture within the working distance of the system, and detects and decodes bar code symbols on objects passing through the omni-directional scanning pattern, and produces symbol character data representative of decoded bar code symbols. In the uni-directional bar code reading mode, the laser scanning engine projects through the light transmission aperture, a visible stroboscopically-pulsed omni-directional laser scanning pattern, against a single laser scanning line having substantially uniform spatial and temporal intensity characteristics at any given scanning plane parallel to the light transmission aperture within the working distance of the system, and detects and decodes bar code symbols on objects passing through the single laser scanning line, and produces symbol character data representative of decoded bar code symbols. A manually-actuatable data transmission switch, integrated with said hand-supportable housing, produces an activation signal in response to the manual-actuation of the data transmission switch. A data transmission subsystem, disposed in the hand-supportable housing, operates under control of control circuitry to communicate the symbol character data produced by the laser scanning engine to a host device operably coupled to the bar code symbol reading device. The control circuitry enables communication of symbol character data produced by the laser scanning engine in the uni-directional bar code reading mode of operation to the host device in response to the activation signal produced by the data transmission switch, and the control circuitry enables communication of symbol character data produced by the laser scanning engine in the omni-directional reading mode of operation to the host device irrespective of the activation signal produced by the data transmission switch.

During the image capture mode, and only when substantially all rows of pixels on the CMOS area image sensing array are enabled and simultaneously ready for photo-integration, the LED-based illumination subsystem is activated so as to produce narrow-band illumination into the FOV of the area image formation and detection subsystem while the automatic light exposure measurement and illumination control subsystem automatically measures the light exposure incident upon a central portion of the FOV, and controls the time duration that narrow-band illumination is produced from the LED-based illumination subsystem.

摘要： The wireless PDT of the present invention employs a “display-on bottom” design which places the unit perfectly centered in the hand of the operator, allowing for the best possible viewing as well as providing comfortable single-handed operation. The high-resolution LCD display allows the PCT to show sharp, clear bitmap images while supporting all Windows-recognized font types and sizes. With the auto back-lit feature, the brightness adjusts automatically making the screen easy to read in all light conditions. The PDT is designed for support within the download/charger cradle of a base station which interfaces with a host system using either USB or RS232 interface. Two standard ‘AA’ or rechargeable Li-Ion batteries provide more than 100 hours of operation. In addition, the PDT comes standard with 2MB of RAM providing enough memory to store over 100,000 records. Applications for the PDT can be developed using a novel integrated development and deployment environment (IDE) which contains an easy-to-use Windows-based application generator and download utilities. For advanced programming, developers can choose to write software using an advanced application generator or ‘C’ programming application generator which provides the developer with simple programming and fast setup. Further enhancements available in the application generator include drag and drop icons, time/datestamp, battery level indicator and variable fonts, giving the developer the ability to create custom screen layouts.

摘要： Disclosed is an automatically-activated wireless code symbol reading system comprising a bar code symbol reading mechanism contained within a hand-supportable housing having a manually-activatable data transmission switch. During symbol reading operations, the bar code symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern with a particular bar code symbol on an object (e.g. product, bar code menu, etc.) so that the bar code symbol is scanned, detected and decoded in a cyclical manner. Each time the scanned bar code symbol is successfully read during a bar code symbol reading cycle, a new bar code symbol character string is produced, while an indicator light on the hand-supportable housing is actively driven. During the bar code symbol reading cycle, the user actuates the data transmission switch producing a data transmission control activation signal and enabling a currently or subsequently produced symbol character data string to be automatically selected and transmitted to the host system. By virtue of the present invention, automatically-activated hand-supportable bar code symbol readers are now able to accurately read, in an unprecedented manner, bar code symbols on bar code menus, consumer products positioned in crowded point-of-sale environments, and other objects requiring automatic identification and/or information access.
