摘要： An automatic digital image capturing and processing system for use in a POS environment, comprising a system having a horizontal housing section, installable within a countertop surface at the POS environment, and supporting at least two area-type illumination and imaging stations for generating and projecting at least two area-type illumination and imaging zones within a 3D imaging volume definable relative to system housing. An object motion detection subsystem automatically detects the motion of objects passing through the 3D imaging volume, and generates motion data representative of detected object motion within the 3D imaging volume. A control subsystem, responsive to the object motion detection subsystem, automatically controls operations within the area-type illumination and imaging stations during system operation. The area-type illumination and imaging zones intersect within the 3D imaging volume, and support automated illumination and imaging of objects passing through the 3D imaging volume, so that digital area-type images of the objects are automatically generated as the objects pass through the area-type illumination and imaging zones within the 3D imaging volume during system operation.

摘要： A POS-based bar code symbol reading system that reads bar code symbols on objects being passed through the 3D imaging or scanning volume supported by the system, and employs one or more object motion sensors (e.g. imaging based, IR Pulse-Doppler LIDAR-based, ultra-sonic energy based, etc.) to (i) measure or estimate the speed of objects being manually passed through the 3D imaging or scanning volume by the system operator, and (ii) visually and/or audibly display object scanning speed measures or estimates to provide the system operator with feedback for optimizing system throughput. The POS-based bar code symbol reading system has a performance advantage that leads to quicker customer checkout times and productivity gain that cannot be matched by the conventional bar code symbol scanning technology.

摘要： An automatic digital image capturing and processing system for use in point of sale (POS) environments, comprising a plurality of coextensive area-type illumination and imaging stations, an object motion detection subsystem, a digital image capturing and buffering subsystem, a digital image processing subsystem, and a control subsystem, each being disposed in a system housing having an imaging window. Each coextensive area-type illumination and imaging station has an area-type imaging array having optics providing a field of view (FOV) on the area-type imaging array that projects into a 3D imaging volume definable relative to the imaging window. Each coextensive area-type illumination and imaging station also has an array of light emitting devices configured together to produce an area-type field of illumination that is coextensive area-type with the FOV of the area-type imaging array, and thereby providing a coextensive area-type illumination and imaging zone that projects through the imaging window and into the 3D imaging volume, for capturing a series of area-type digital images of an object intersecting therewith during system operation. During system operation, the object detection subsystem automatically detects the motion of objects moving through the 3D imaging volume, and generates motion data which is used by the control subsystem to control at least one illumination control parameter associated with the production of the area-type fields of illumination produced from the coextensive area-type illumination and imaging stations, during system operation. The coextensive area-type illumination and imaging zones intersect within the 3D imaging volume for digital imaging of objects passing through the 3D imaging volume.

摘要： An optical reader for decoding an encoded symbol character of a symbology includes a scan data signal processor having as an input a scan data signal encoding information representative of the encoded symbol character. The scan data signal processor includes a first time delay stage adapted to provide a primary phase waveform from the scan data signal, a second time delay stage adapted to provide an early phase waveform from the scan data signal, and a third time delay stage adapted to provide a delayed phase waveform from the scan data signal. The early phase waveform has a propagation delay less than the primary phase waveform, and the delayed phase waveform has a propagation delay greater than the primary phase waveform. The scan data signal processor further includes a peak window detection stage for generating a peak window timeframe when an amplitude of the primary phase waveform is greater than, less than, or equal to both an amplitude of the early phase waveform and the delayed phase waveform. The optical reader further includes a digitizer circuit adapted to accept, within the peak window timeframe, the scan data signal processor output.
