System and method for surgical telementoring and training with virtualized telestration and haptic holograms, including metadata tagging, encapsulation and saving multi-modal streaming medical imagery together with multi-dimensional [4-d] virtual mesh and multi-sensory annotation in standard file formats used for digital imaging and communications in medicine (dicom)
The invention relates generally to a medical apparatus and method of using the same for receiving and transmitting streaming medical imagery and audio signals in real time, and allowing remote operators to annotate and telestrate with same. The invention acquires streaming medical imagery and audio signals through a telestreamer input device, allowing users to electronically collaborate, generally by telestrating, annotating, and sketching image overlays on streaming medical imagery.

Self-learning hearing assistance system and method of operating the same
A method of operating a system for providing hearing assistance involves capturing audio signals by a manually controlled transmission unit having a user interface and default values setting transmission unit operating parameter storage, and transmitting audio signals from the transmission unit to a receiver unit, the audio signals being processed in the receiver unit and/or in the transmission unit; stimulating the user's hearing according to the audio signals from the receiver unit; logging user preference data by recording data concerning the manual operation of the user interface of the transmission unit and by recording data concerning the respective use situation of the transmission unit; evaluating, in the transmission unit, the logged user preference data to extract user preferences concerning use of the transmission unit; and adjusting, in the transmission unit, the stored default values of the at least one operating parameter setting according to said extracted user preferences.. .

Direction of arrival estimation using watermarked audio signals and microphone arrays
An apparatus for providing direction information based on a reproduced audio signal with an embedded watermark includes a signal processor, which is adapted to process at least two received watermarked audio signals recorded by at least two audio receivers at different spatial positions. The signal processor is adapted to process the received watermarked audio signals to obtain a receiver-specific information for each received watermarked audio signal.

Secured audio channel for voice communication
A security device for hindering data theft and data leaks via audio channel of a computer system is based on passing the audio signals through a coding vocoder that receives input audio signal from a computer and compressing the signal to a low bit-rate digital data indicative of human speech; and a decoding vocoder that decompress the digital data back to a secure audio signal. The data transfer of the protected audio channel is intentionally limited not to exceed the bit-rate needed to carry vocoder-compressed human speech which is well below the capabilities of unprotected audio channel.
