摘要： Disclosed is an automatically-activated wireless code symbol reading system comprising a bar code symbol reading mechanism contained within a hand-supportable housing having a manually-activatable data transmission switch. During symbol reading operations, the bar code symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern with a particular bar code symbol on an object (e.g. product, bar code menu, etc.) so that the bar code symbol is scanned, detected and decoded in a cyclical manner. Each time the scanned bar code symbol is successfully read during a bar code symbol reading cycle, a new bar code symbol character string is produced, while an indicator light on the hand-supportable housing is actively driven. During the bar code symbol reading cycle, the user actuates the data transmission switch producing a data transmission control activation signal and enabling a currently or subsequently produced symbol character data string to be automatically selected and transmitted to the host system. By virtue of the present invention, automatically-activated hand-supportable bar code symbol readers are now able to accurately read, in an unprecedented manner, bar code symbols on bar code menus, consumer products positioned in crowded point-of-sale environments, and other objects requiring automatic identification and/or information access.

摘要： A method of illuminating objects using adaptively controlled mixing of spectral illumination energy to form and detect digital images of objects at a POS. The method comprises providing, at a POS environment, a digital image capture and processing system having a system housing with an imaging window, and an area-type illumination and imaging station disposed within said system housing, for projecting a coextensive area-type illumination and imaging field (i.e. zone) through said imaging window into a 3D imaging volume during object illumination and imaging operations. As the object is moved through the 3D imaging volume, its motion is automatically detected, and signals indicative of said detected object motion are generated. In response to the generated signals, a first field of visible illumination is produced from an array of visible LEDs, simultaneously with a second field of invisible illumination from a array of infrared (IR) LEDs. These first and second fields of illumination spatially overlap and intermix with each other to produce a composite wide-area illumination beam that is at least substantially coextensive with the FOV. During object illumination and imaging operations, the relative power ratio (VIS/IR) of these fields of visible illumination and invisible illumination is adaptively controlled as one or more digital images of the illuminated object are formed and detected, captured and buffered, and ultimately processed so as to read one or more 1D and/or 2D code symbols graphically represented in the digital images.

摘要： 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. When the visible laser light source, the scanning element and the plurality of stationary mirrors are arranged in a second configuration, these components cooperate to produce a visible omni-directional laser scanning pattern having temporally varying intensity characteristics, against a single visible laser scanning line having substantially uniform spatial and temporal intensity characteristics, at a given scanning plane parallel to the scanning window within the working distance of the system.

摘要： 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. In the uni-directional bar code reading mode, the laser scanning engine projects through the light transmission aperture, a visible stroboscopically-pulsed omni-directional laser scanning pattern, against a single laser scanning line having 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 single laser scanning line, and produces symbol character data representative of decoded bar code symbols. A manually-actuatable data transmission switch, integrated with said hand-supportable housing, produces an activation signal in response to the manual-actuation of the data transmission switch. A data transmission subsystem, disposed in the hand-supportable housing, operates under control of control circuitry to communicate the symbol character data produced by the laser scanning engine to a host device operably coupled to the bar code symbol reading device. The control circuitry enables communication of symbol character data produced by the laser scanning engine in the uni-directional bar code reading mode of operation to the host device in response to the activation signal produced by the data transmission switch, and the control circuitry enables communication of symbol character data produced by the laser scanning engine in the omni-directional reading mode of operation to the host device irrespective of the activation signal produced by the data transmission switch.

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. In the uni-directional bar code reading mode, the laser scanning engine projects through the light transmission aperture, a visible stroboscopically-pulsed omni-directional laser scanning pattern, against a single laser scanning line having 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 single laser scanning line, and produces symbol character data representative of decoded bar code symbols. A manually-actuatable data transmission switch, integrated with said hand-supportable housing, produces an activation signal in response to the manual-actuation of the data transmission switch. A data transmission subsystem, disposed in the hand-supportable housing, operates under control of control circuitry to communicate the symbol character data produced by the laser scanning engine to a host device operably coupled to the bar code symbol reading device. The control circuitry enables communication of symbol character data produced by the laser scanning engine in the uni-directional bar code reading mode of operation to the host device in response to the activation signal produced by the data transmission switch, and the control circuitry enables communication of symbol character data produced by the laser scanning engine in the omni-directional reading mode of operation to the host device irrespective of the activation signal produced by the data transmission switch.

摘要： 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 scanning mode or a single line scanning mode. In the omni-directional scanning mode, the laser scanning engine projects an omni-directional scanning pattern through the light transmission aperture, 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. In the rastered scanning mode, the laser scanning engine projects rastered scanning pattern through the light transmission aperture and detects and decodes bar code symbols on objects passing through the single line scanning pattern, and produces symbol character data representative of decoded bar code symbols. In the single-line scanning mode, the laser scanning engine projects a single line scanning pattern through the light transmission aperture and detects and decodes bar code symbols on objects passing through the single line scanning pattern, and produces symbol character data representative of decoded bar code symbols. A manually-actuatable data transmission switch, integrated with said hand-supportable housing, produces an activation signal in response to the manual-actuation of the data transmission switch. A data transmission subsystem, disposed in the hand-supportable housing, operates under control of control circuitry to communicate the symbol character data produced by the laser scanning engine to a host device operably coupled to the bar code symbol reading device. The control circuitry enables communication of symbol character data produced by the laser scanning engine in the single line or rastered scanning mode of operation to the host device in response to the activation signal produced by the data transmission switch, and the control circuitry enables communication of symbol character data produced by the laser scanning engine in the omni-directional scanning mode of operation to the host device irrespective of the activation signal produced by the data transmission switch.

摘要： A laser illumination beam generation system including a laser diode (LD) for producing a laser beam in response to a diode current supplied thereto, wherein the laser beam has a central characteristic wavelength. Diode current drive circuitry generates the diode current and supplies the same to the VLD. A high frequency modulation (HFM) circuitry modulates the diode current supplied to the laser diode, so as to produce a spectral side-band components about the central characteristic wavelength, and thereby reduces the coherence of the laser illumination beam as well as its coherence length. An optical multiplexing (OMUX) device receives the laser beam as an input beam and generates multiple laser beams therefrom and recombines the multiple laser beams so as to produce a composite output laser illumination beam having reduce coherence.
