Abstract: A method of conducting cardless and cashless transactions is disclosed. A user, such as from a plurality of students of one or more clients or schools, presents a familiar user ID number and a PIN at a participating merchant. A server receives the user ID and PIN from the merchant and builds a probationary user account number from the user ID, and a client ID associated therewith. The user ID number is padded to a greater number of digits to form the user account number to ensure it is unique amongst many users and clients at the server. Before approving the transaction, the server ascertains whether the user account number and PIN is on record and if so, then further establishes if the user has a sufficient balance in a user sub-ledger account in a source bank account corresponding with the user account number. Periodically, a settlement is made between the source account and various merchant bank accounts.

Abstract: A photosensitive medium, such as motion picture film, having digital audio signals photographically recorded thereon. If the medium has multiple, spatially separated digital and analog audio soundtracks, a photosensitive detector array is employed for each of the digital audio soundtrack areas, and a separate analog soundtrack read head is employed. Preferably, digital error code is recorded in a digital soundtrack area of the medium (with digital audio bits), and error detection and correction are performed on the recorded digital audio bits read from the medium. Preferably, the apparatus includes switching circuitry for substituting a corresponding analog audio signal for one or more corrupted digital soundtrack channels, when such digital soundtrack channels have an error rate which exceeds a selected threshold.

Abstract: A method and apparatus for photographically recording digital audio signals, and a medium having digital audio signals photographically recorded thereon. In a preferred embodiment, a motion picture film recorded in accordance with the invention has multiple digital audio soundtracks and an analog audio soundtrack photographically recorded thereon. Two or more channels of digital audio information can be recorded in each digital soundtrack, along with additional digital information for clocking, tracking, and error detection and correction. Each digital soundtrack is recorded in an array of bit areas arranged in row and column order. In a class of preferred embodiments, each row of digital audio bits is recorded simultaneously by exposing the film to radiation that has been modulated by a linear shutter array. The radiation transmitted by each shutter array is projected onto a row of spots. Each spot covers the full width of one of the bit areas in a row, but only part of the length of the bit area.

Abstract: An add-on module for a contact printer used to manufacture a motion picture. The module enables the printing of a digital optical soundtrack on motion picture film from a sound negative using a standard contact printing process. The module includes spaced apart guide rollers and a main roller. Unexposed film is placed in contact between the main roller and the sound negative. The module further includes a fiber optic light source positioned adjacent to the sound negative for exposing the film and forming the digital soundtrack. The digital soundtrack is formed on a portion of the positive print which includes an area between each of the sprocket holes. In addition, the digital soundtrack extends from each sprocket hole to the edge of the positive print on both sides of the print.
