摘要： A method and apparatus of driving a motor in a light scanning arrangement. The method includes the following steps: (1) driving a drive coil with a drive signal to oscillate a scan mirror and a light beam reflected from the scan mirror; (2) generating a feedback signal having zero crossings during oscillation of the scan mirror by a feedback coil in proximity to the drive coil; (3) integrating the feedback signal to generate an integrated feedback signal; and (4) processing the integrated feedback signal to generate a periodic drive signal that has the same time period as the feedback signal.

摘要： Illumination driver circuit for using in an imaging-based barcode reader is configured to provide the driving current for the illumination source with a Buck regulator when the driving current is above a threshold current value and to provide the driving current for the illumination source with a linear regulator when the driving current is not above the threshold current value. The threshold current value is substantially close to the smallest current the Buck regulator operative to provide when operating in a continuous mode.

摘要： A wavelength selector in an optical scanner is operative for selecting a first laser beam having a predetermined wavelength to produce a first scan pattern, and for selecting a second laser beam having a different wavelength to produce a second scan pattern. The scan patterns have a different number of scan lines. The selected scan pattern is scanned over indicia, e.g., a bar code symbol, to be read.

摘要： A method for setting voltage resolution in particle beam measuring devices wherein band width of a measured signal processing is modified. In order to set a desired voltage resolution simply, reliably, and with high precision, a signal noise of the measured signal is measured. This signal noise is compared to a desired value for the measured signal resolution, and the band width of the measured signal processing is modified such that the signal noise of the measured signal is less than or equal to the desired value for the measured signal resolution.

摘要： A method for representing logic changes of state occurring at a plurality of adjacent circuit nodes in an integrated circuit in the form of a logic image employs a pulsed electron probe which always scans a same path in the x-direction on the integrated circuit and the phase of the electron pulses comprising the pulsed electron probe is continuously shifted for each new scanning operation. The integrated circuit can be imaged up to the edge of a recording or field of view limit and it is only at this limit that the y-deflection of the pulsed electron probe is fixed. Very small spacings, such as those occurring between adjacent integrated circuit tracks, can thus be reliably imaged on the picture screen of the scanning electron microscope.
