A method and system for processing of physiological signals is provided. The system processes information signals in subband-domain associated with the physiological signals in time-domain. The information signals are obtained by one or more over-sampled filterbanks. The method and system possibly synthesizes the subband signals obtained by subband processing. The method and system may implement the analysis, subband processing, and synthesis algorithms on over-sampled filterbanks, which are implemented on ultra low-power, small size, and low-cost platform in real-time. The method and system may use over-sampled, Weighted-Overlap Add (WOLA) filterbanks.

A method and system for data logging in a listening device is provided. The system includes a digital signal processing (DSP) entity, which performs normal hearing aid audio and system processing, a level translating module, and a non-volatile (NV) memory. The NV memory is used to store logged data. During the hearing aid audio processing, the DSP entity communicates with the NV memory via the level translating module. The level translating module performs voltage-translation during data logging to a communication signal between the DSP entity and the NV memory.

Method and system for protecting content in a programmable system is provided. The system is connectable to an external device through one or more access port. Content protection method/manager is implemented by assigning one or more access modes to the access port and switching the access modes. In response to a current access mode, the content protection method/manager restricts visibility of the system to the external device via the access port.

Abrégé

In accordance with the teachings described herein, systems and methods are provided for a hearing instrument with self-diagnostics. A detection circuitry may be used to monitor the functional status of at least one transducer by measuring an energy level output of the transducer and comparing the energy level output to a pre-determined threshold level. The detection circuitry may generate an error message output if the measured energy level output of the transducer falls below the pre-determined threshold level. A memory device may be used to store the error message output generated by the detection circuitry.

Abrégé

A vent configuration for a hearing instrument comprises a vent tube having a length and a vent opening, and at least one cell positioned around the periphery of the vent tube. The at least one cell is closed at a first inner end and open at an outer end, which is adjacent the vent opening. The cell is a tube that extends around the periphery of the vent tube along a portion of the length of the vent tube. A hearing instrument incorporating the vent configuration is also included.
