Abstract: A hearing aid system is described that includes a hearing aid and a companion microphone, separate from the hearing aid itself, for improving the understanding of speech spoken by a particular person or produced by a particular sound source. Also described are techniques for dealing with the problem of how to make a robust directional microphone that requires no user input as to the orientation of the companion microphone.

Abstract: A portable patient communicator (PPC) includes a portable housing that supports a processor coupled to memory for storing medical firmware and wireless radio firmware, first and second radios, a processor, and a power source. Communications between a patient implantable medical device (PIMD) and the first radio of the PPC are effected in accordance with program instructions of the medical firmware, and communications between the second radio of the PPC and the wireless network are effected in accordance with program instructions of the wireless radio firmware. Data from the PIMD is received via the first radio to which a priority level is assigned, such as in a tiered manner. A data transport mechanism is selected among disparate data transport mechanisms based at least in part on the priority level. PIMD data is transmitted to the wireless network using the selected transport mechanism via the second radio.

Abstract: An implantable pulse generator communicates with external devices such as device programmers and network repeaters to exchange data. The communication utilizes a communication protocol such that data is transferred in packets and transport control information is included for each of the packets. Network routing information may also be provided for each of the packets to establish additional capabilities including network addressing, priority control, or recipient validation. Information exchange instructions are executed by the implantable pulse generator to take data from one or more application programs being executed by the implantable pulse generator, divide the data into packets, and add the transport control information, and network routing information if desired, for outgoing packets.
