Abstract
A high speed non-contact beam scanning data acquisition memory card is disclosed. The device possesses the ergonomic benefits of a a card, yet can scan a wide angle moving beam across an information-bearing target in one or two dimensional scan patterns such as lines, rasters or other patterns in order to read information therefrom. The device is well suited for reading one or two dimensional bar-code or other printed matter where great portability as in medical records acquisition is desired. In order to achieve the high density electro-optical packaging necessary for its high performance to size ratio the present device employs a low profile scan module which is turned on by novel methods. Collected information is processed by signal processing electronics and stored in solid state low power memory devices. Novel triggering and scan actuating methods are also disclosed as are novel integrated scanning applications. In one embodiment components are integrated into a thin PCMCIA card or pen type scan device. Communication from the device is achievable by a cable or by wireless means.
