    摘要: A system for selectively acquiring, processing and displaying 3-D waypoints in a manner suitable for the purpose of providing selected hands-free navigation guidance to a user. The system includes a plurality of multi-function devices for defining a frame of reference, at least one of the plurality being adapted to be carried by the user. A communication link provides communication between the plurality of multi-function device means to form a mesh network. The multi-function devices calculate, exchange and process waypoint information indicative of the location of itself, the device carried by the user, and at least one other the device means to thereby provide the route taken by the user. A display gives a 3-D navigation guidance to the user.

    摘要: A method and apparatus for introducing a time-varying time delay randomly into the individual reproduction channels of a sound recording, two in the case of binaural presentation. This emulates the temporal aspect of microphone and/or listener motion. The present invention may be applied as a unidirectional process. No preparation of the source material is required. It can be applied to any multichannel audio signal set. It can process analog or digital signals. The process may be used with headphones, loudspeakers, hearing aids or similar assistive hearing devices.

    摘要: A method for dynamically adjusting the spectral content of an audio signal, which increases the harmonic content of said audio signal, said method comprising translating an encoded digital signal into data bands, creating a psychoacoustic model to identify sections of said data bands that are deficient in harmonic quality, analyzing the fundamental frequency and amplitude of said harmonically deficient data bands, creating additional higher order harmonics for said harmonically deficient data bands, adding said higher order harmonics back to said encoded digital signal to form a newly enhanced signal, inverse filtering said newly enhanced signal, and converting said inverse filtered signal to an analog waveform for consumption by the listener.
