Latest Patents

One of Waring's latest patents is titled "Medium having photographically recorded digital audio bits." This invention involves a photosensitive medium, such as motion picture film, that has digital audio signals photographically recorded on it. The medium can accommodate multiple, spatially separated digital and analog audio soundtracks. A photosensitive detector array is utilized for each digital audio soundtrack area, along with a separate analog soundtrack read head. The invention also includes a digital error code recorded in a digital soundtrack area, enabling error detection and correction on the recorded digital audio bits. Furthermore, the apparatus employs switching circuitry to substitute a corresponding analog audio signal for any corrupted digital soundtrack channels when their error rate exceeds a selected threshold. The method of reading recorded digital audio information involves projecting a laser beam with a near-infrared wavelength onto a row of a digital soundtrack area of motion picture film, allowing for precise modulation as the film translates continuously.

Another significant patent is the "Method and apparatus for photographically recording digital audio." This invention describes a method and apparatus for recording digital audio signals photographically, with a medium that has multiple digital audio soundtracks and an analog audio soundtrack. The preferred embodiment features a motion picture film that records two or more channels of digital audio information in each digital soundtrack, along with additional digital information for clocking, tracking, and error detection. Each digital soundtrack is recorded in an array of bit areas arranged in rows and columns, with the recording process being analogous to painting the bit area with a paintbrush.
