Publication number: 20160173986Abstract: An ultra-low distortion loudspeaker is described. The ultra-low distortion, on the order of 0.1% THD (total harmonic distortion) or less, is achieved by novel means. The signal from a typical preamplifier, i.e., line level signal, is fed into an ultra-low distortion, high order band-pass filter, the band-pass filter splitting the component frequencies into various bands. Secondly, the output of each band, or group of bands, is then input to an ultra-low distortion power amplifier, each driving an individual acoustic transducer. The band-pass filters, power amplifiers, and acoustic transducers, along with a suitable enclosure(s), comprise an ultra-low distortion integrated loudspeaker system.Type: ApplicationFiled: December 14, 2015Publication date: June 16, 2016Inventor: Gary Lloyd Fox

Patent number: 5666547Abstract: A method and apparatus for identifying at least a portion of a framing pattern in a data stream comprising a plurality of sequential bits. In the method embodiment, the method includes the step of identifying a set of successive candidate bits wherein the identified candidate bits are spaced apart from one another. The successive candidate bits include a first candidate bit, a last candidate bit, and a predetermined number of intermediary bits between the first candidate bit and the last candidate bit. Each of the intermediary bits has a numeric relative position between the first candidate bit and the last candidate bit. The method further includes the step of identifying a group of look ahead bits corresponding to each of the intermediary bits. Each of the groups has a number of look ahead bits, and the particular number of such bit for a given group equals the magnitude of the numeric relative position for the intermediary bit corresponding to the group.Type: GrantFiled: September 23, 1994Date of Patent: September 9, 1997Assignee: Alcatel Network Systems, Inc.Inventors: Gary Lloyd James, Jeremy David Omas
