The present invention is a bar code verification device having an ergonomic form factor characterized by a domed hand held trigger and a viewing window. The verification device may be disposed in a network that includes a host processor system and other bar code reading devices which may include other bar code verification devices. Processing circuitry for processing image signals corresponding to printed bar codes may be partially disposed within the hand held verification device and partially disposed within a host processor system spaced apart from and associated with the hand held verification device. The hand held verification device may be in wireless communication with the host processor system to which it is associated. The bar code verification system may include signal enhancement modules which interpolate constructed pixel values from actual pixel values and which correct for signal degradation resulting from high frequency spatial sampling.

A data collection device is configured so that the device receives and processes various radio signals and automatically changes an operating mode of the data collection device in response to the processing of the radio signals or in response to the presence or absence of radio signals without manually inputting any commands with use of a user interface. By configuring the data collection device to automatically change an operating mode in response to sensed radio signals, operating modes are presented to an operator that may be tailored to the preferences of the present operator and/or tailored to the particular requirements of the device at present location of the device. With highly featurized operating modes being automatically and selectively presented to operators under specific circumstances, an operator is relieved of a variety of burdensome and time consuming exercises that are typically associated with learning how to access particular functions of a highly featurized electronic device.

A laser scanning bar code symbol reading system having a scanning window, from which blue/red beam-waist-extended laser scanning planes are projected and intersect within an extended depth of field (DOF) defined adjacent the scanning window. In the illustrative embodiment, the laser scanning bar code symbol reading system includes a laser scanning subsystem having: a dual laser sources for producing a laser beams having blue and red spectral components; a collimating lens for collimating the laser beams; an aperture stop for shaping the cross-sectional dimensions of the collimated the laser beams; and beam-waist extending optics (e.g. axicon-lens) for extending the waist of the laser beam having a red characteristic wavelength.

An indicia decoding device can have an image sensor and a laser diode assembly configured to project laser light onto a substrate. When a trigger signal is received by the indicia decoding device, the device can calculate a delay and enable the laser diode assembly if a delay threshold is satisfied. The indicia decoding device, in one embodiment, can include a hand held housing and an imaging module carrying the image sensor.

The invention features a system and method to automatically focus an image reader using a single frame of image data. The method comprises exposing sequentially a plurality of rows of pixels in the image sensor. The method further comprising varying in incremental steps the focus of the image reader's optical system from a first setting where a distinct image of objects located at a first distance from the image reader is formed on the image sensor to a second setting where a distinct image of objects located at a second distance from the image reader is formed on the image sensor. As part of the method, the varying of the focus of the optical system occurs during the exposure of the plurality of rows of pixels.

Systems and methods for making and using handheld data readers comprising one or more fluid lenses. One or more fluid lenses are provided to allow a handheld data reader to perform such operations as reading indicia, including such additional operations as zooming, reorienting a viewing direction, focusing, adjusting an optical axis, and correcting for the effects of motion such as hand jitter. The fluid lens or lenses can be operated for example by applying electrical signals to fluid lenses comprising a plurality of fluids including at least one that is conductive and at least one that is non-conductive.
