  • Patent number: 9635478
    Abstract: A hearing aid output amplifier additionally outputs a scaled replica of the output battery current, which is integrated and measured by a coulomb counter. The scaled current charges a capacitor. When the capacitor reaches a threshold voltage, a switch is activated. The switch rapidly discharges the capacitor and allows the charging cycle to begin again. The switch also sends a digital pulse to a digital counter, which keeps track of the number of charge/discharge cycles the capacitor has undergone over the lifetime of the device. The amount of charge produced by the battery is proportional to the number of charge/discharge cycles counted. A hearing aid is disclosed, which has different modes that have different dynamic ranges, such as a “sleep” mode, an “active” mode, and/or an “RF communication” mode.

  • Patent number: 9521493
    Abstract: A hearing aid is disclosed, which, in a test mode, can determine the impedance of the transducer that stimulates the anatomy of the patient. Impedance may be determined by simultaneous determination of the current flowing through the transducer and the voltage across the transducer. In some cases, the output amplifier of the hearing aid includes two outputs, with one being a scaled and/or summed replica of the other. The amplifier is driven with a periodic signal with a particular frequency and a known peak voltage. The periodic signal may be sinusoidal. The primary output of the amplifier is electrically connected to the transducer, with a known current given by the peak input current and a known gain of the amplifier. The voltage from the secondary output of the amplifier is measured. The impedance is calculated by dividing the measured voltage from the secondary output of the amplifier by the known current.

  • Patent number: 9451368
    Abstract: A hearing aid is disclosed, having the ability to generate its own open-loop feedback scan of amplitude (as gain or attenuation) and phase, as a function of frequency. The hearing aid has a sensor that receives ambient sound from near a patient, and a driver that stimulates the anatomy of the patient. The hearing aid has an operational mode in which the driver stimulates the anatomy of the patient in response to the sound received at the sensor. The hearing aid has a test mode in which a test frequency is stepped through a predetermined range of frequencies. At each test frequency, the driver is driven with a sinusoidal driver signal at the test frequency, the sensor detects a sinusoidal sensor signal at the test frequency, and a comparison of the sensor signal to the driver signal produces an amplitude (gain or attenuation) and a phase for the test frequency.
