    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: A method and apparatus for establishing a bi-directional communication link between a reader and a base station using wireless charging components includes positioning the reader within the base station, and electrically charging a rechargeable power source of the reader by an induced current carried through an induction coil in response to an electromagnetic field generated by an induction coil of the base station. The reader receives a communication parameter that uniquely identifies a short-range communication transceiver of the base station by detecting a modulation in the induced current. In response, a short-range communication transceiver of the reader transmits an RF signal that includes the identification data and a request to establish a bi-directional communication link with short-range communication transceiver of the base station. In response to receiving the identification data and the request, the base station and the reader establish a bi-directional communication link via a short-range wireless communication protocol.
