Patent ID: 7013702

Claim:
A dynamic pressure waveform generator comprising: a controller operable to produce electronic signals over a range of frequencies, amplitudes and waveforms, wherein said electronic signals are representative of a fluid pressure in a living body; a transducer operable to convert said electronic signals into a dynamic pressure waveform, wherein said transducer comprises: a magnet; a movable coil, wherein said electronic signals pass through said movable coil to induce a magnetic field in said movable coil, and wherein said movable coil is attracted to or repelled by said magnet based on said electronic signals passed through said movable coil; a diaphragm connected to said movable coil; and a chamber, wherein said chamber is sealed at least in part by said diaphragm, which forms at least a portion of said chamber and an outer surface of said transducer, and wherein a movement of said movable coil generates said dynamic pressure waveform inside said chamber; and one or more receptacles connected to said chamber for coupling one or more pressure-sensing devices to said chamber.
