摘要： A circuit for digitizing an analog signal generated from a photoelectric conversion of reflected light when scanning indicia having spatially-separated, light-reflective portions bounded by edges includes a differentiator for differentiating the analog signal. An inverter inverts the differentiated signal to generate an inverted signal. A negative peak detector detects negative amplitude peaks and a positive peak detector detects positive amplitude peaks of the differentiated signal and generate, respectively, a negative and positive peak signal. Adders are used to add the positive peak signal to the inverted signal, and the negative peak signal to the inverted signal. A comparator compares the two summed signals to the differentiated signal and generates pulse signals indicative of the edges of the analog signal. A controller, in response to the pulse signals, generates a digital signal corresponding to the indicia being scanned.

摘要： A holographic grating element is provided which enables tracing different scan lines. The element is divided into a plurality of sectors. A first grating pattern is provided which diffracts a beam in one direction, and a second grating pattern is next to the first and diffracts the scan beam in the reverse direction. Sectors can be produced with different sector sizes to enable scanning at different rates in the reverse direction, or in successive scans in the same direction. Angle relationships are described to produce diffraction patterns for a desired relationship between disc rotation and the angle of the scan line.

摘要： A drive circuit for a bar code scanner for driving an oscillatory resonant motor therein which periodically oscillates in opposite rotary directions to impart an oscillatory motion to a scanning mirror of the bar code scanner. In the disclosed drive arrangement, the motor is driven at its own natural resonant frequency, which requires very little current to maintain the oscillatory motion. A scanning beam is directed against the oscillating scanning mirror, which causes the beam to be periodically scanned across a field of view of the bar code scanner. A detector detects reflections of the scanned beam, as by a bar code symbol being scanned, and generates an output signal representative thereof. The resonant motor, having a rotor with a permanent magnet mounted thereon, drives the scanning mirror, and includes a drive winding positioned adjacent to the permanent magnet for applying a driving force thereto only in a first rotary direction, and a feedback winding also positioned adjacent to the permanent magnet for deriving a substantially sinusoidal feedback voltage as the permanent magnet periodically passes in opposite directions by the feedback winding. A drive circuit for the resonant motor includes a drive amplifier coupled to the feedback winding which is turned on only by positive halves of the feedback voltage. A driver transistor is coupled between the drive amplifier and the drive winding to drive the motor only during positive halves of the feedback voltage. A return biasing spring drives the rotor in the second rotary direction.

摘要： An illumination time of an illumination system and/or an exposure setting of an imaging system are adjusted by a proximity system operative for detecting a product entering a field of view in a bi-optical, dual window, point-of-transaction workstation. The proximity system includes an infrared emitter for emitting infrared light to the product, and an infrared sensor for sensing return infrared light from the product. Multiple predefined thresholds are stored for the sensed return infrared light, and a predefined illumination time and/or exposure setting are stored and assigned to each predefined threshold. Adjustment of the illumination time and/or of the exposure setting is performed by comparing the sensed return infrared light from the product in real time operation with the stored predefined thresholds.

摘要： A bi-optical, dual window, point-of-transaction workstation images indicia associated with multi-sided products over a full coverage scan zone by splitting each field of view of only two imagers into three subfields that pass through each window and fill the scan zone and minimize dead areas therein. Twisting of the subfields relative to the windows is minimized so that the subfields fit fully with minimal clipping through each window. Splitting of each field of view is remotely performed well away from each imager. The imagers have lens assemblies of substantially the same optical power and are spaced from their respective windows by substantially the same distance.

摘要： A reader for and method of electro-optically reading symbols aim a front of a handheld housing at a symbol during reading. A solid-state, low resolution image sensor having a linear array of pixels is arranged in the housing and has less than 2000 pixels in number. The pixels sense return light returning along an optical path away from the symbol that is located in an extended range of working distances relative to the front of the housing. An imaging lens is positioned deep in the housing at an increased spacing of at least one inch as measured along the optical path away from the front of the housing, for capturing the return light over a reduced scan angle that is less than 40 degrees, and for projecting the captured light onto the sensor. A controller processes the return light sensed by the imager into data relating to the symbol.
