    摘要： Embodiments of the present invention comprise an indicia reading terminal including a focus element that extends the range of focus distances at which the indicia reading terminal can decode decodable indicia. In one embodiment, the focus element comprises a variable form element and a variable position element, the combination of which causes an image distance that can change in accordance with a separation distance between these two elements. The focus element can comprise an actuator, e.g., a piezoelectric actuator, which can be coupled to the variable position element in a manner that can cause the variable position element to deform the variable form element, and in one example, the deformation changes the focal length of the variable form element.

    摘要： A computer assembly having a host computer and a detachably attached computer expansion module. The computer expansion module includes a 2D imaging module, and may include short range imaging optics. In a “picture taking” mode actuated by input into the host computer, the expansion module captures an image, and without launching a decoding algorithm, sends the captured image to the host computer which displays the image on an integrated display of the host computer. In a “decode” mode actuated by input to the host computer, the expansion module captures an image, executes a decoding algorithm, and sends a decoded out message to the host computer, which displays the decoded out message on an integrated display of the host computer.
