Abstract: A computerized “smart card” which has a read/write memory and formatted data storage blocks is used to track the life history of one or more associated machine(s) (e.g., vehicles, medical instrumentation and apparatus, business and copying machines, etc.). The smart card can store a variety of information including machine identification, hardware/software specifications, debit/credit, regulated performance, warranty/insurance, maintenance/service and operational transactions that might impact the hardware, software or the intended operation or performance of the machine. The smart card will be equipped to interact with any of a plurality of autonomous reader/writer smart card units and computer-based reader/writer smart card units that may be equipped to interact with any of the plurality of computer databases through the utilization of land or wireless communications links.

Abstract: A device and method for stimulation of visual perception by a subject having his eyes closed, by illuminating the closed eyelids with light pulses, particularly in association with music or other sounds provided to his or her ears. Different light pulse sequences can be applied to the subject's two eyes, for instance simultaneously with the two channels of stereo sound supplied to the subject's ears. The device is provided so that the sound signal modulates the visual signal, such as the widths and separations of the light pulses in the light pulse sequences illuminating the subject's eyes, in a manner to which the subject's senses are particularly responsive. With such stimulation of the senses, the subject can perceive or observe, with closed eyes, a large variety of patterns and colors in his visual field. The patterns and colors occur and change on a variety of time and space scales, in some correspondence with the sound, but with some non-reproducible or chaotic characteristics as well.
