摘要： Systems and methods of conducting a bar code scan using an imaging-based bar code scan device are provided. In one exemplary embodiment, a method is performed by an imaging-based bar code device that includes processing circuitry, an optical lens assembly having an image sensor and an optical lens with a focused region at a certain distance in front of the optical lens along an optical axis of the optical lens, a plurality of light emitting elements configured proximate the optical lens and laterally offset from the optical axis. The method includes sending, by the processing circuitry, to each light emitting element, an indication to enable that light emitting element to project a light beam towards the optical axis in the focused region so that the light beams overlap when a target bar code is in the focused region and nonoverlap when a target bar code is outside the focused region.

摘要： An instant switching method for a computer-television system is described. The computer-TV system is separated into a TV operating module and a computer operating module, individually. An input/output device of the TV operating module is used for both modules of the system. When booting the system, the TV mode is first entered since the TV operating module controls the I/O system in the beginning. In the meantime, the computer system is performing the P.O.S.T. process and entering a standby mode later. The booting process of the computer is almost done while a user switches the TV mode to the computer mode.
