    Abstract: A slot scanner illumination system for a convertible slot scanner assembly includes a chassis having an optical cavity and a front opening. The optical cavity has an optical axis therethrough, with the optical axis being an axis along which light may be received by the chassis through the front opening. The front opening further has a first edge and a second edge opposite the first edge. A scanning window is configured to at least partially cover the front opening of the chassis, and the scanning window has a normal axis orthogonal to a flat surface of the scanning window. An illumination element is disposed inside of the optical cavity of the chassis. The illumination element is disposed proximal the first edge of the front opening. The illumination element is configured to provide illumination along an illumination axis, wherein the illumination axis is non-parallel with the optical axis and at an angle directed toward the second edge of the front opening.

    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: Slot scanners with wakeup systems are disclosed herein. An example slot scanner assembly includes a wakeup system having an infrared (IR) transmitter configured to project IR illumination through a window of the slot scanner and an IR receiver. The IR receiver has a second field-of-view (FOV) directed through the window that overlaps a first FOV of an imaging assembly of the slot scanner by at least 50% at the window and has a second central axis that is non-perpendicular to the window such that the second central axis is tilted downward from horizontal with the slot scanner assembly positioned in a vertical first configuration where the window is in a generally upright orientation. A controller of the slot scanner is configured to activate an illumination system when the IR receiver detects IR illumination reflected from an object in the second FOV of the IR receiver.
