267 results about "Floppy disk" patented technology

A floppy disk, also known as a floppy, diskette, or simply disk, is a type of disk storage composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic enclosure lined with fabric that removes dust particles. Floppy disks are read and written by a floppy disk drive (FDD).

System and method for delivering and examining digital tickets

A digital ticket is procured by a client ticket consumer upon, preferably, the Internet from and by staged interaction with a ticket provider server. The digital ticket becomes embodied in a tangible transportable data storage medium, normally a 2-D bar code printed on paper by the consumer, or on the consumer's flexible disk or smart card, containing Sign(s,I||hash(R))||R where (1) R is a number having its origin in the computer of the ticket consumer, which number R is appended to (2) a number Sign(s,I||hash(R)). This number Sign(s,I||hash(R)) was earlier computed in the computer of the ticket provider as a digital signature using signature key s of a number hash(R) combined with event information I, and was subsequently communicated across the communications network to the computer of the ticket consumer. The number hash(R) was itself even earlier computed in the computer of the ticket consumer as a one-way function of random number R, which computed one-way function was subsequently communicated to the computer of the ticket provider. The number R is private to the ticket consumer and not public; the digital signature key s is private to the ticket provider.The digital ticket is redeemed by (1) transporting the transportable storage medium within which the Sign(s,I||hash(R))||R is written to the particular selected event; (2) tendering the digital ticket for verification and for admission; (3) reading the Sign(s,I||hash(R))||R to an event computer and extracting the number R; (4) decrypting the remaining Sign(s, I||hash(R)) with verification key v of the ticket producer to get hash(R) and I; (5) re-calculating from R, with the same one-way function previously used, a re-calculated hash(R); then, having this recalculated hash(R) to hand; (6) comparing the re-calculated hash(R) to the extracted hash(R). The (4) decrypting will work, producing a proper I for the selected event, and the (6) comparing will be equal, only for a legitimate ticket.

Display and storage device

A device for holding, storing and displaying various media articles, such as CDs, CD Cases, DVDs, DVD Cases, Audio Cassettes, Audio Cassette Cases, Computer Mini-floppies, Video Cassette, Video Cassette Cases, Books, Magazines, Pictures, Cards and the like. The device is comprised of a single sheet of relatively thin pliable, resilient material, such as a sheet of vinyl, plastic, and the like, within and through said material are cut a plurality of slits, in sets of two or more slits or slit sets. The lower ends of slit sets are spaced apart by a distance which is less than the transverse dimension of an article to be supported or held, while the upper ends are spaced apart at a distance which is greater than the transverse dimension of said article to be supported or held. The lower ends and upper ends of slit sets are longitudinally spaced apart by a distance that is less than the longitudinal dimension of an article to be supported or held. The lower ends of a slit set are even on the horizontal axis while the upper ends of a slit set has at least one slit that is uneven, shorter or offset from at least one other slit on the horizontal axis. When an article is inserted into the space between slits in a slit set, the material deforms to form a compartment that captures or holds a portion of said article. Compartments are formed from a plurality of slits and/or slit sets and are open-topped/top-loading and are integrally formed with the sheet material. Compartments are capable of receiving at least one article and maintaining the article in an upright position, relatively parallel with the overall plane of the device with at least one part of the article visible for viewing. A slit sets size, shape and spacing is relatively proportional to the size, shape and/or dimensions of the articles thereby forming compatible compartments for the article. A portion of an article is within the compartment and a portion is exposed so as to permit a single article to be easily accessible and grasped by the fingers for easy placement and/or removal there from. The device is mountable to supports, such as a wall, door, and mirror or hung from racks etc.
