Abstract: An optical code symbol reading system includes a housing having a light transmission aperture, and at least one sound port formed in the housing. The system includes an optical code symbol reading subsystem for optically reading a code symbol in the field external to the light transmission aperture, and generating symbol character data representative of the read code symbol. An electro-acoustic transducer is disposed in the housing for producing sonic energy. Also, an acoustic-waveguide structure is disposed in the housing, for coupling the sonic energy produced from the electro-acoustic transducer, to the at least sound wave port formed the housing, to audibly signal the reading of a code symbol to the operator of the optical code symbol reading system.

Abstract: An automatic automatically-triggered digital video imaging based code symbol reading system for use in point of sale (POS) environments, employing an adaptive control process involving the real-time analysis of the exposure quality of captured frames of digital image data and the real-time reconfiguration of system control parameters (SCPs) based on the results of such exposure quality analysis. By virtue of the present invention, the system enables the reliable reading of code symbols graphically represented in digital images, under demanding point-of-sale lighting conditions and other challenging environments.

Abstract: A digital image capture and processing system for automatically recognizing objects at a point of sale (POS) station. The system comprising a system housing having an imaging window, and containing a digital image capturing and processing engine including a plurality of coplanar illumination and imaging stations. The stations generate and project a complex of coplanar illumination and imaging planes through the imaging window, and within a 3D imaging volume definable relative to the imaging window for omni-directional imaging of objects passing through the 3D imaging volume, and generate digital linear images of the object as the object intersects coplanar illumination and imaging planes within the 3D imaging volume during system operation. A database is provided for storing one or more object libraries representing objects that can be recognized by the system.

Abstract: An automatic digital video image capture and processing system supporting image-processing based code symbol reading during a pass-through mode of system operation at a retail point of sale (POS) station. The system comprises an automatic object direction detection subsystem, disposed in its housing, as well as an illumination subsystem, an image formation and detection subsystem, an automatic illumination control subsystem, a digital image capturing and buffering subsystem, a digital image processing subsystem, and a system control subsystem. During system operation, the automatic object direction detection subsystem automatically detects the presence and direction of movement of the object in the field of view (FOV), and in response thereto, generates a first signal indicating a triggering event and a second signal indicating the direction of movement of the object with respect to the FOV.

Abstract: An automatically-activated bar code reading system including: a visible laser light source, scanning element and a plurality of stationary mirrors. When arranged in a first configuration, the visible laser light source, scanning element and plurality of stationary mirrors cooperate to produce a visible omni-directional laser scanning pattern with multiple laser scanning lines having substantially uniform spatial and temporal intensity characteristics at a given scanning plane parallel to a scanning window within a working distance of the system.

Abstract: A multi-mode laser-based bar code symbol reading device having a hand-supportable housing with a light transmission aperture, wherethrough visible light can exit and enter the hand-supportable housing. A laser scanning engine, disposed within the hand-supportable housing, is controlled to selectively operate in either an omni-directional reading mode or a uni-directional bar code reading mode. In the omni-directional bar code reading mode, the laser scanning engine projects pattern through the light transmission aperture, an omni-directional laser scanning pattern producing multiple laser scanning lines with substantially uniform spatial and temporal intensity characteristics at any given scanning plane parallel to the light transmission aperture within the working distance of the system, and detects and decodes bar code symbols on objects passing through the omni-directional scanning pattern, and produces symbol character data representative of decoded bar code symbols.
