摘要： A system and method for controlling an amplifier in a bar code reader are disclosed, wherein the method may include receiving light at a photodiode within the bar code reader from a bar code being scanned by a scan mirror powered by a scan motor; converting the received light into an initial electrical signal; determining whether the scan motor is undergoing a change in direction; establishing a gain value for the amplifier based on an outcome of the determining step; and amplifying the initial electrical signal into an amplified signal using the established gain value.

摘要： A system and method for reading a bar code are disclosed which may include transmitting light pulsed at a selected frequency to illuminate the bar code; converting light received at the bar code reader from the bar code into an electrical signal; transmitting the electrical signal through a signal conditioning circuit to filter and amplify the electrical signal, to thereby provide a conditioned electrical signal; sampling the conditioned electrical signal at the selected frequency; removing energy due to light scattering within a housing of the bar code reader from the sampled, conditioned electrical signal; generating one of a logical "1" and a logical "0" output based on a value of the signal generated by the step of removing; and resolving output from the step of generating into data indicative of information on the bar code.

摘要： A compact barcode reader is provided in which the imaging lens and a linear sensor are in a straight line path with the barcode (no bend in path). By using a wide angle lens with a short back focus, it is possible to reduce the distance between the barcode and linear sensor to a fraction of what it was in the prior art. In addition, the maximum image height and the downward projection of the sensor are reduced to a fraction of what they were in the prior art. As a result, despite the straight line optical path, compact barcode reader becomes so small that it does not interfere with the operation of the beverage maker.
