Abstract: A method of activating an illumination assembly within a symbology reader is provided, the illumination assembly having a first illumination source and a second illumination source, the symbology reader having an imaging sensor configured to operate at a predetermined framerate where each frame includes an exposure period over which the imaging sensor is active to capture image data and a non-exposure period over which the imaging sensor is not active to capture image data, the method comprising: during a first frame, activating the first illumination source during at least a portion of the respective exposure period and activating the second illumination source over at least a portion of the respective non-exposure period; and during a second frame, activating the second illumination source during at least a portion of the respective exposure period and activating the first illumination source over at least a portion of the respective non-exposure period.

Abstract: An adapter for a portable barcode reader includes a body having a base for selective placement on an external surface, adapter electrical contacts contained within the body and positioned to be in continuous electrical contact with reader electrical contacts of the portable barcode reader in a fastened state, a wireless charging receiver conductor coupled to the adapter electrical contacts, and a wireless controller configured to control charging of the portable barcode reader. The adapter maintains the portable barcode reader in a stationary position when placed on a surface such that the field of view of the portable barcode reader extends from horizontal to as much as 45 degrees below horizontal. The adapter may further include a near-field communication conductor and a microcontroller to wirelessly communicate indicia data captured by the portable barcode reader to an external receiver.

Abstract: Systems and methods for calibrating an adaptive illumination system of an imager are presented. An example method includes causing the system to enter a calibration mode and providing a calibration illumination level from an illumination source to an environment. An imager captures one or more images of the environment. A processor determines, from the one or more images, a first illumination intensity to provide during an object detect mode operation of the system. The first illumination intensity has an illumination sufficient for detecting a presence of an object in the environment during the object detect mode. The processor stores the first illumination intensity in a memory, and configures the illumination source to provide illumination at the first illumination intensity while the adaptive illumination system is in the object detect mode, and (ii) provide illumination at a second illumination intensity while the adaptive illumination system is in a scanning mode.

Abstract: Systems for alternative illumination in global shutter barcode readers are disclosed herein. An example system includes an imaging apparatus configured to capture an image during an image capture period, and an imaging shutter configured to actuate and expose the imaging apparatus to an external environment during the image capture period. The example system also includes an illumination light emitting diode (LED) configured to emit illumination, and an illumination drive circuit configured to cause the illumination LED to emit the illumination (i) during the image capture period and (ii) when the imaging apparatus is shielded from exposure to the external environment by the imaging shutter.
