Latest Patents

One of her latest patents is focused on intrabody communication with ultrasound. This innovative hearing system consists of a first device that acoustically couples to the skin of the user and includes a sensor to detect acoustic signals. The second device features a hearing stimulator arrangement that stimulates the user's hearing in response to the acoustic signals detected by the first device. Both devices are capable of bidirectionally communicating through an ultrasonic communication link that utilizes a portion of the user's body. Another notable patent involves interference suppression techniques. This system includes an acoustic sensor array coupled to a processor, which processes inputs from the array to extract a desired acoustic signal while suppressing interfering signals. The extraction and suppression are achieved by modifying the array inputs in the frequency domain with weights selected to minimize variance of the resulting output signal while maintaining unity gain of signals received in the direction of the desired acoustic signal. This system has potential applications in hearing aids, voice input devices, surveillance devices, and more.
