An automatic data collection device is provided for reading barcodes, matrix codes, stacked codes, or other machine-readable symbol. The data collection device generates an aiming beam that serves a dual purpose of target locating and data acquisition, such as data acquisition using imaging methods. The aiming beam defines the field of view of the data collection device for imaging. The illumination pattern provided by the aiming beam for imaging can have its shape, size, and/or intensity adaptively changed depending on conditions.

Functional aiming system for an automatic data collection device, such as an image acquisition device

A system and method of detecting a barcode involves obtaining a two-dimensional source image and converting it into a frequency domain image (FDI). Frequency trends in the FDI are then analyzed to determine whether barcode information is present in the FDI. In this way, the presence, location, orientation, size and symbology of a barcode can be quickly and accurately determined.

Detecting barcodes on two-dimensional images using frequency domain data

A reader such as a barcode reader identifies at least one potential target such as a barcode symbol in its field-of-view, and projects or transmits an indicator toward or proximate the potential target containing information about the respective potential target. Such information may include which target is currently active, the symbology in which the target is encoded, the relative position of the reader with respect to the target, the ability of the reader to decode the target, and/or ranked or sorted order information regarding the target and neighboring targets. The reader may rank, sort, prioritize or otherwise determine order based on various parameters, including symbology, position in field-of-view, size, etc., and may base such on past history of the reader and/or user, and may weight such.

Methods, apparatuses and articles for automatic data collection devices, for example barcode readers, in cluttered environments

A method of operating a device having at least one solid-state memory and at least one spinning media memory for storing data includes from time-to-time, determining whether the device is in motion; and in response to determining that the device is not in motion, transferring frequently accessed data between the spinning media memory and the solid-state memory. An apparatus for use with a device includes at least one solid-state memory; at least one spinning media memory; and a controller configured to transfer frequently accessed data between the spinning media memory and the solid-state memory when the device is not in motion.

System and method of ruggedizing devices having spinning media memory, such as automatic data collection devices having hard disk drives
