Abstract
Abstract An apparatus which is a single portable device for scanning and downloading data. The apparatus employs a laser within an optical scanner to accomplish both scanning and downloading functions. In addition to the optical scanner, the apparatus employs control and communication circuitry for switching from scanning to downloading and for modulating an outgoing laser beam during downloading. A modulating material, such as a liquid crystal display or electrochromic lens, is excited to modulate the outgoing laser beam passing through it. The optical scanner also includes a motor-driven mirrored spinner which may be stopped to accomplish a high rate of data transfer during downloading using a highly directional beam.
