Publication number: 20140296619Abstract: The present application discloses hearing prostheses with two modes of operation and methods for operating the prostheses. In the first mode of operation, a hearing prosthesis receives a microphone input and produces an output based on the microphone input. In the second mode of operation, the hearing prosthesis may detect an accessory input signal and switch to an accessory input mode. The second mode of operation may produce an output that is based at least in part on the accessory input signal. Some embodiments may include detecting an accessory input signal with a detector. In response to detecting an accessory input signal, the hearing prosthesis may switch to an accessory operation mode. When the accessory input signal is not detected, the hearing prosthesis may operate in microphone operation mode.Type: ApplicationFiled: February 28, 2014Publication date: October 2, 2014Inventors: Alexander Case, Rami Banna, David Thambiratnam, Felicity Allen

Publication number: 20140275730Abstract: A method for adjusting parameters of a hearing prosthesis system includes adjusting a control to shift an audiogram associated with a first stimulator, applying a prescription rule using the shifted audiogram to adjust a cross-over frequency that defines a first frequency range and a second frequency range. The first stimulator is configured to apply stimulation signals in the first frequency range and a second stimulator is configured to apply stimulation signals in the second frequency range. The method also includes applying the prescription rule using the shifted audiogram to determine gain and maximum power output (MPO) levels for the first frequency range associated with the first stimulator.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Inventors: Stefan Lievens, Thomas Stainsby, Rami Banna, Christopher J.

Patent number: 8559573Abstract: A communications circuit includes a filter module with a sampling window, a control module, and an input buffer. The control module has a ray parameter interface to obtain information regarding significant ray changes that make it desirable to re-position the sampling window. The control module determines re-positioning parameters, responsive to this information, which reflect the re-positioning of the sampling window. The input buffer obtains samples of a received signal and outputs received signal data to the filter module. The filter module obtains the re-positioning parameters from the control module, and the filter module and control module temporally re-position the sampling window in duration and/or location in accordance with the re-positioning parameters, and output a filtered chip.Type: GrantFiled: December 27, 2005Date of Patent: October 15, 2013Assignee: Agere Systems LLCInventors: Rami Banna, Tomasz T.

Publication number: 20130265144Abstract: A system that includes an implanted medical device such as an auditory prosthesis having a capacity to conduct communications on two channels to establish an association for communication with another electronic device. One of the channels is preferably a short range or near field channel, and the other channel is a broadcast channel. A method of asynchronous communication using both channels for establishing the association is also described.Type: ApplicationFiled: October 26, 2011Publication date: October 10, 2013Inventors: Rami Banna, Justin Gilmour, Werner Meskens, Brian Gordon

Publication number: 20130223663Abstract: A system and method for wireless streaming link break-in is disclosed. A first device transmits digital packets to a second device over a wireless streaming link. A third device synchronizes itself with the second device. Once the third device is synchronized with the second device, the third device transmits command request packets to the second device during a data receive window. The wireless streaming link is inactive during the data receive window. The second device responds to the request during a next data receive window.Type: ApplicationFiled: February 28, 2012Publication date: August 29, 2013Inventors: Rene Roos, Werner Meskins, Philip Gielis, Alex von Brasch, Orlando Wu, Rami Banna

Patent number: 8462839Abstract: In one embodiment, a receiver has a reference generator and a main equalizer. The reference generator equalizes a received signal using one or more pilot reference signals. Then, the reference generator decodes one or more predetermined data channels of the equalized signal, makes hard decisions on the data of each decoded channel, and regenerates the original coding sequence of each decoded channel. The main equalizer uses each re-encoded channel as an additional reference signal along with one or more pilot signals to equalize a time-delayed version of the received signal. In alternative embodiments, the receiver might also have a step-size generator which selects optimum step sizes from a look-up table based on the number of re-encoded channels and the power of those channels. The step size is then used by the main equalizer along with the re-encoded channels to equalize the time-delayed received signal.Type: GrantFiled: December 6, 2011Date of Patent: June 11, 2013Assignee: Agere Systems LLCInventors: Rami Banna, Uwe Sontowski, Long Ung, Graeme K.

Publication number: 20120226331Abstract: The present application discloses systems and methods for distributed processing of electrophysiological signals. The system may include a processor, a remote device, and an implant comprising an array of electrodes. The method may comprise the processor receiving an electrophysiological signal request from the remote device that specifies at least one electrode at the implant from which to receive an electrophysiological signal, transmitting to the implant instructions to apply a plurality of stimuli via the specified at least one electrode and, for individual stimuli in the plurality of stimuli, recording an electrophysiological signal component resulting from the stimulus. The method may also comprise the processor combining the recorded individual electrophysiological signal components to produce the electrophysiological signal and transmitting the electrophysiological signal to the remote device for further processing.Type: ApplicationFiled: March 1, 2011Publication date: September 6, 2012Inventors: Rami Banna, Andrew Botros

Publication number: 20120197065Abstract: The present application discloses systems and methods for displaying and operating a user interface having one or more channel group controllers corresponding to one or more groups of hearing prosthesis channels. The hearing prosthesis may be configured to generate a plurality of signals via a plurality of channels based on a channel profile. The channel profile may define at least one intensity level for each channel. In operation, the user interface may be configured to instruct the hearing prosthesis to change the channel profile of the plurality of channels in response to receiving an input via one of the channel group controllers. The user interface may be used to fit a hearing prosthesis to a recipient. In one embodiment, an initial channel profile may be automatically determined, and the prosthesis channel profile may be adjusted by changing a representative intensity level corresponding to the channel profile.Type: ApplicationFiled: January 28, 2011Publication date: August 2, 2012Applicant: Cochlear LimitedInventors: Andrew Botros, Bastiaan van Dijk, Rami Banna

Publication number: 20090296798Abstract: In one embodiment, an HSDPA co-processor for 3GPP Release 6 Category 8 (7.2 Mb/s) HSDPA that provides all chip-rate, symbol-rate, physical-channel, and transport-channel processing for HSDPA in 90 nm CMOS. The co-processor design is scalable to all HSDPA data rates up to 14 Mb/s. The coprocessor implements an Advanced Receiver based on an NLMS equalizer, supports RX diversity and TX diversity, and provides up to 6.4 dB better performance than a typical single-antenna rake receiver. Thus, 3GPP R6 HSDPA functionality can be added to a legacy R99 modem using an HSDPA co-processor consistent with embodiments of the present invention, at a reasonable incremental cost and power.Type: ApplicationFiled: April 5, 2007Publication date: December 3, 2009Applicant: Agere Systems Inc,.Inventors: Rami Banna, Mark A.
