    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.

    摘要： An arrangement for damping the resonance in a laser diode includes an additional layer (25) which together with the conventional laser diode form a structure (35) of a bipolar transistor. Therein, the additional layer serves as the collector, the cladding layer (12) next to it as the base, and the active region (11) and the other cladding layer (13) as the emitter. A capacitor (30) is connected across the base and the collector. It is chosen so that at any frequency above a certain selected frequency (f.sub.c) which is far below the resonance frequency (f.sub.res) the capacitor impedance is very low, effectively shorting the base to the collector.

    摘要： A portal system for secure, aggregated and centralized management and access of disparate customer service and social networking environments is disclosed. A user interface provides multiple, parameter-based automated service scripts, each configured to utilize customer information. The scripts link to vendor-specific, scenario-specific, and social networking-specific interfaces that have common user interface elements. Shared and dedicated reverse automation gateways are configured to emulate the step-by-step self-service aspects of web sites and interactive voice response systems. The portal system eliminates or reduces inbound toll-free telephone charges for vendor contact centers and additionally links the same to social networking systems.
