Latest Patents

Walter Etter's latest patents include a "System and method for location determination utilizing direct path information." This innovative system determines the location of a receiver, such as sensors carried by a device like a robot. The method involves receiving an audio signal in response to a predetermined audio signal from at least two audio source devices. It estimates the first impulse response between each audio source device and the receiver, removing reflections to create direct path information. This information is then used to determine the receiver's location.

Another significant patent is for "Noise compensation methods and systems for increasing the clarity of voice communications." This technology controls the amount of noise compensation applied to a signal, operating as both a noise-adaptive expander and compressor based on noise level estimates from both far-end and near-end sources.
