摘要： Crosstalk between a drive coil and a feedback coil is eliminated by a motor drive circuit operative for generating the drive coil as a square wave, and by removing the crosstalk which occurs at zero transitions of a feedback signal. The drive coil is used to oscillate a scan mirror employed in an image projection arrangement or an electro-optical reader.

摘要： A programmable imaging pixel array and barcode imager incorporating the same are provided where the aspect ratio of each pixel of the imaging pixel array can be changed to better match the type of barcode being imaged. For lower density barcodes that are far away from the barcode imager, for example, the aspect ratio of the imaging pixel array can be programmed on the fly to maximize aspect ratio and thereby increase the signal-to-noise ratio in the received signal. When reading high density barcodes, such as PDF417 barcode symbols, the aspect ratio of the imaging pixel array can also be programmed on the fly to obtain an aspect ratio which does not compromise the performance of the barcode imager.
