    摘要: A laser scanning assembly includes a coil support element having a central axis about which is wound an electromagnetic wire coil and having a flange oriented generally transverse to the central axis. At least one elastomeric flexural element has a first end coupled to the flange. A permanent magnet has first and second surfaces, a central axis, and a magnetization direction oriented generally transverse to the central axis of the permanent magnet. The magnet is supported by a second end of the elastomeric flexural element. A mirror has a central axis and is mounted on the second surface of the magnet. The central axes of the mirror and magnet are coaxial with the central axis of the coil support element. The elastomeric flexural element provides a return force when the magnet and the mirror are rotated at an angle from the central axis during energization of the electromagnetic wire coil.

    摘要: A laser scanning system for generating a laser scanning pattern in a scanning field, while amplifying the scan-angle multiplication factor of rotating mirrors employed therein. The laser scanning system employs rotatable laser scanning assembly having an axis of rotation and first and second rotating mirrors with normal vectors that are coplanar with each other and said rotational axis, and which form an acute angle substantially less than 90 degrees so as to provide a laser scanning assembly with a scan angle multiplication factor that is greater than 2.0. A cluster of stationary mirrors mounted about the first and second rotating mirrors, for sweeping a laser beam off the cluster of stationary mirrors after a laser beam has been reflected off the first rotating mirror, then reflected off the second rotating mirror, and then directed outwardly towards an array of pattern mirrors, so as to generate a resultant laser scanning pattern within the scanning field.

    摘要: A digital-imaging based code symbol reading system which automatically detects hand-induced vibration when the user attempts to read one or more 1D and/or 2D code symbols on an object, and controls system operation in order to reduce motion blur in digital images captured by the hand-supportable system, whether operated in a snap-shot or video image capture mode. An accelerometer sensor is used to automatically detect hand/system acceleration in a vector space during system operation. In a first embodiment, digital image capture is initiated when the user manually depresses a trigger switch, and decode processed only when the measured acceleration of the hand-supportable housing is below predetermined acceleration threshold levels. In another embodiment, digital image capture is initiated when an object is automatically detected in the field of view of the system, and decode processed only when the measured acceleration of the hand-supportable housing is below predetermined acceleration threshold levels.

    摘要: A modular omnidirectional laser-based bar code symbol scanning system having at least one scan module insert that is removably disposed within a system housing through a service port in the system housing. The scan module insert is a self-contained unit including at least the following components: at least one laser diode (11A1', 11A2'), a rotating scanning element (13A'), an electric motor (15A') that rotates the rotating scanning element, one or more photodetectors (17A1', 17A2'), and analog signal processing circuitry that conditions the electrical signal produced by the one or more photodetectors. The scan module insert can optionally include additional components including one or more light collecting , optical elements, one or more beam folding mirrors, circuitry for detecting and decoding bar code symbols scanned by the system, etc. The modular architecture of omnidirectional laser scanner of the present invention enables quick access to the scan module insert for efficient repair/reconfiguration/configuration of the optical components, electro-optical, electro-mechanical components and/or electrical components.

    摘要: The effects of paper/substrate noise are significantly reduced in multifocal zone laser scanning systems (1) by processing analog scan data signals with a scan data signal processor having a plurality of pass-band filters and amplifiers (13A-13D) that are automatically selected for passing only the spectral components of an analog scan data signal produced when a bar code symbol is scanned at a particular focal zone (FZ1-FZ5) in the laser scanning system. Two or more different pass-band filter structures can be provided for use in the scan data signal processor, wherein each pass-band filter structure is tuned to the spectral band associated with a particular focal zone in the laser scanning system. When a bar code symbol is scanned by a laser beam focused within the first focal zone or scanning range of the system, the pass-band filter structure associated with this focal zone or scanning range is automatically switched into operation.
