Apparatus and methods for converting one type of speech processor unit into another type of speech processor unit.

Speech processor cases

Sound processors and systems including sound processors are disclosed.

An implantable device includes a stimulation electronic circuit, a battery, a receiver configured to receive energy from a source external to the implantable stimulation device, and a battery charger circuit configured to use the energy to charge the battery and power the stimulation electronic circuit, the battery charger circuit including a load switch for connecting/disconnecting the battery, the load switch being controlled by the stimulation electronic circuit.

Methods of converting a behind-the-ear speech processor unit into a body worn speech processor unit

A push-pull amplifier efficiency provides a 4:1 (12 dB) course adjustment of power output by using a single digital control input. The amplifier is provided with an input voltage (VDD) having sixteen steps ranging from 1.25 volts to 3.00 volts. Based on the digital control, an integrated circuit switches between a high power mode and a low power mode. In the low power mode, the output voltage is equivalent to the input voltage. In the high power mode, the amplifier provides an output of twice the input voltage (or four times the power).

The accuracy of neural response recordings in neural stimulators, e.g., cochlear implants, is often degraded by a recording artifact. An idealized electrical-equivalent model of a neural stimulator is created to study, measure and compensate for artifact evoked compound action potential (eCAP). Using this model, the artifact is shown to occur even when the electrical components that make-up the neural stimulator are ideal. The model contains parasitic capacitances between the electrode wires. The model demonstrates that these small parasitic capacitances provide a current path during stimulation which can deposit charge on the electrode-tissue interfaces of the recording electrodes. The dissipation of this residual charge and the charge stored across the stimulating electrode is seen as the recording artifact. The proposed solution for eliminating the artifact problem is realized by utilizing a capacitive electrode material, e.g., TiO, TaO, or other dielectric coatings or films, instead of Faradaic electrode material, e.g., Platinum (Pt), Pt&#x2014;Ir alloy or similar alloys, on the neural stimulator electrode lead.

Systems for facilitating communication between a first and second device include a voltage level translator circuit configured to convert a voltage level of one or more digital signals that are transmitted from the first device to the second device to a voltage level substantially equal to a supply voltage level of the second device. The conversion is based on a first input voltage signal into the translator circuit. The systems further include a diode in series with a capacitor. The diode is configured to generate the first input voltage signal by charging the capacitor to a voltage level that is substantially equal to the voltage level of the one or more digital signals.
