Patent number: 9473130Abstract: Various aspects of the disclosure are directed to methods and apparatuses involving providing a clock signal. As consistent with one or more embodiments herein, a sawtooth waveform signal is generated in a manner that facilitates low power operation. In some implementations, the sawtooth waveform signal is generated using an oscillator that operates without necessarily employing R-C circuits and/or without rail-to-rail voltage supply, such as via a nonlinear oscillator. The sawtooth waveform signal is used to generate a trapezoidal waveform signal, and a clock signal is generated using the trapeziodal waveform signal.Type: GrantFiled: October 8, 2013Date of Patent: October 18, 2016Assignee: NXP B.V.Inventors: Chiahung Su, Madan Mohan Reddy Vemula

Patent number: 9357318Abstract: 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: GrantFiled: February 28, 2014Date of Patent: May 31, 2016Assignee: Cochlear LimitedInventors: Alexander Case, Rami Banna, David Thambiratnam, Felicity Allen

Patent number: 9278209Abstract: A cochlear implant electrode includes an implantable array carrier made of flexible material with electrode contacts distributed on its outer surface along a longitudinal axis. Electrode wires are embedded within the array carrier, each electrode wire having a terminal end electrically connected to a corresponding electrode contact for applying electrical stimulation signals carried by the electrode wires to adjacent neural tissue within the cochlea. Each electrode wire has an inner non-crystal conductive material surrounded by a flexible outer seal. The flexible material of the array carrier is configured to be reactive with the non-crystal conductive material of the electrode wires so that if a break occurs in the outer seal of an electrode wire that allows contact between the flexible material and the non-crystal conductive material, then a local leakage seal will form at the break that resists migration of the non-crystal conductive material to the outer surface of the array carrier.Type: GrantFiled: September 8, 2014Date of Patent: March 8, 2016Assignee: MED-EL Elektromedizinische Geraete GmbHInventors: Stefan Strahl, Anandhan Dhanasingh, Claude Jolly
