Abstract
Hearing aid fitted with a central processing unit (1) having peripherals (3E, 3A) connected to its input and output respectively. Each peripheral includes an identification unit (5) having an the output connected to a first input of a comparator (9). A second input of the comparator is connected to a read-only identification memory (11) containing identification features of the peripherals. An output of the comparator drives a configuration memory (15). As a result, the hearing aid self-identifies its current configuration based on the identification of the peripherals.
Claims19
A hearing device comprising:
- a digital signal processing unit having inputs and outputs;
- at least one self-contained hardware unit, peripheral with respect to said digital signal processing unit and operationally connected to said inputs of said digital signal processing unit;
- an identification means in said peripheral self-contained hardware unit, the identification means having an output and containing identification information identifying said hardware unit;
- a storage unit remote from said hardware unit containing identification information identifying more than one hardware peripheral unit and having an output;
- a comparing unit remote from said hardware unit and having a first input, a second input, and an output, said output of said identification unit being operationally connected to the first input and said output of said storage unit being operationally connected to the second input and
- a memory unit being operationally connected to the output of said comparing unit for storing the current configuration of said hearing device with respect to said peripheral self-contained hardware unit.
A method for manufacturing a hearing device, comprising the steps of:
- providing a signal processing unit;
- providing at least one self-contained peripheral hardware unit;
- operationally connecting said peripheral self-contained hardware unit to said signal processing unit;
- and
- automatically identifying said peripheral self-contained hardware unit;
- and
- storing the current hardware configuration of the hearing device with respect to said peripheral units.
