    摘要： A new approach to capturing and reproducing either live or recorded three-dimensional sound is described. Called MTB2.5 for “Motion-Tracked Binaural 2.5,” the method employs six real or simulated microphones, a head tracker, and special signal-processing procedures to combine the signals picked up by the microphones. In the microphone array, two central microphones are placed at the positions of the ears of a listener facing forward, and four peripheral microphones are located in pairs on either side of the central microphones. Only the low-frequency components of the four peripheral microphone signals are needed, and the total bandwidth required is approximately 2.5 times the bandwidth of one full-bandwidth audio channel. MTB2.5 achieves a high degree of realism by effectively placing the listener's ears in the space where the sounds are occurring, moving the virtual ears in synchrony with the listener's head motions. MTB2.5 also provides a universal format for recording spatial sound.

    摘要： A new approach to tracking head motion for headphone-based sound is described. Called MTB2.0 for “Motion-Tracked Binaural with 2 Channels”, the method may be used for any 2-channel binaural signals without any increase in the bandwidth requirement. MTB2.0 provides a simple and effective means to improve the quality of headphone-based sound reproduction by sensing the orientation of the listener's head and using the sensed orientation to appropriately modify the signals sent to the two ears. MTB2.0 method increases the realism and removes some of the shortcomings of binaural sound capture and recording, as well as improves the quality of binaural rendering of stereo.

    摘要： A pressure sensing element has at least a housing containing a fluid. The housing has at least two moveable surfaces in contact with the fluid in the housing; There is a first moveable surface comprising a pressure application surface which, when moved towards, away from, into or out of the fluid, creates a change in fluid pressure and a second moveable surface in contact with the fluid in the housing comprising a membrane which, when deformed by pressure changes in the fluid, alters its electrical resistance. The membrane has two electrodes attached to deformable material in the membrane. The membrane my have an elastomer having conductive particles distributed therein. The elastomer may be a dielectric and the particles are conductive nanoparticles.
