摘要： A bar code scanner and method for scanning a bar code symbol that splits a light beam using a liquid crystal device and directs the split light beams toward a bar code symbol using a moveable mirror. The light reflected by the symbol from each of the split light beams is summed and converted to an electrical signal indicative of the bar code symbol. The electrical signal is processed to decode the bar code symbol, but, if decoding is unsuccessful, the liquid crystal device is changed to affect the number of split light beams incident on the bar code symbol.

摘要： Several different embodiments are disclosed of a simple, compact bar code scanner which is capable of scanning in any one of several modes, a linear scan mode for scans along a single axis, an omnidirectional scan mode for scans with consecutive scan lines which are angularly displaced relative to each other, or a raster scan mode for scans with consecutive scan lines along a first scan axis which are displaced relative to each other along a second perpendicular axis. In a preferred embodiment, the compact bar code scanner is used in a small housing mounted on an index finger of an operator such that the natural pointing direction of the index finger aims the scanner. In one embodiment, a high frequency flexural member, with a scanning mirror and permanent magnet mounted thereon, is supported by a low frequency flexural member. An x drive coil is positioned by the permanent magnet, and with an applied high frequency x drive signal, causes the high frequency flexural member, with the permanent magnet means and scanning mirror mounted thereon, to torsionally oscillate at the frequency of the x drive signal. A y drive coil is also positioned by the permanent magnet, and with an applied low frequency y drive signal, causes the low frequency flexural member to oscillate to cause low frequency y scanning of the scanning mirror, thereby resulting in a raster scan pattern. With an applied high frequency y drive signal, the y coil causes the high frequency flexural member to oscillate at a high frequency to cause high frequency y scanning of the mirror, thereby resulting in an omnidirectional scan patterns.

摘要： A hand-held bar code reader, in particular a bar code wand is used by a consumer to read bar code information accompanying a product displayed at a retail outlet. The bar code information can be presented in, for example, UPC format and carries information relating to the products. The consumer subsequently down-loads information stored in the reader via a suitable interface to a personal computer which accesses information identified by a address included in or comprising the bar code information. The site contains additional information such as price information concerning the advertised product and the consumer may be able to pay for and order the product directly via the site. As a result the consumer has a simple reminder of the product, is able to obtain additional information concerning the product with minimum difficulty and can obtain the product itself with maximum ease.

摘要： A bar code scanner employs an electronic means for causing the light beam to scan a bar code symbol, rather than using a mechanical device to generate the scan. A linear array of light sources, activated one at a time in a regular sequence, may be imaged upon the bar code symbol to simulate a scanned beam. Instead of a single linear array of light sources, a multiple-line array may be employed, producing multiple scan lines. The multiple scan lines may be activated in sequence, or activated simultaneously (time-division or frequency-division multiplexed. The multiple scan lines can provide signal enhancement, noise reduction or fault correction if directed to the same bar code pattern. Multiple scan lines may be generated using a single light source and a beam splitter, with mechanical scanning, as well as by the sequentially-activated light sources. Multiple simultaneous scan lines may be employed to generate a raster scan at lower mechanical scan frequency. In another embodiment, a tunable laser may be employed to provide a scan without moving parts; a laser beam from the tunable laser is reflected from a diffraction grating that produces an angular deviation dependent upon the wavelength of the laser output. As the frequency of the tunable laser is varied in some selected pattern, the laser beam will scan accordingly.

摘要： Disclosed are methods and apparatus for automatically aligning the field of view of a two dimensional bar code reading device with a randomly oriented two-dimensional bar code symbol wherein the symbol comprises a unique pattern located contiguously on at least one side thereof. One method is implemented in a laser based embodiment by scanning the symbol with a laser scan line extending through the border pattern (which is a PDF417 start codeword), measuring the length of the start codeword detected by the scan line, and rotating the laser scan line by a predetermined amount. This is repeated for a predetermined number of times, and the rotation angle at which the codeword length is smallest is determined by performing a least squares fit of the measured codeword lengths and rotation angles. The raster pattern is then rotated to the determined rotation angle so as to be aligned with the symbol for subsequent scanning and decoding. In the alternative, a sequential least squares fit can be performed after each start codeword measurement is made rather than waiting for all measurements to be made. An alternative embodiment implements a discrete radial CCD array comprised of linear CCD arrays which enables angular scanning of the target symbol, wherein a two-dimensional CCD array is then rotated either physically or logically by the calculated skew angle in order to be aligned with the symbol for imaging and subsequent processing and decoding.
