Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
101 words
Apparatus for providing three-dimensional aural signals to a user comprising: sensor means for providing a first signal responsive to the existence of a real time predetermined condition; three-dimensional aural signal generator means for providing an output aural signal to said user, said output aural signal having a spectral shape indicative of a directional location relative to said user of said predetermined condition; means for applying said first signal to said generator means for activating said generator means to produce said three-dimensional aural signal; and means for applying preselected portions of said three-dimensional aural signal independently to each ear of said user.
Claim 2
Dependent Claim
101 words
Apparatus for providing three-dimensional aural signals to a user comprising: sensor means for providing a first signal responsive to the existence of a real time predetermined condition; three-dimensional aural signal generator means for providing an output aural signal to said user, said output aural signal having a spectral shape indicative of a directional location relative to said user of said predetermined condition; means for applying said first signal to said generator means for activating said generator means to produce said three-dimensional aural signal; and means for applying preselected portions of said three-dimensional aural signal independently to each ear of said user.
