    摘要: Described is state switch for a hearing aid that provides an input to the hearing aid's processing circuitry indicating that battery power has been disconnected by a power switch. The state switch and power switch are configured to operate in parallel. The state switch may provide a signal to a GPIO (general purpose input-output) of the processing circuitry indicating that the battery has been disconnected. Immediately after the battery is disconnected, voltage is maintained for a brief period due to the capacitance of the circuitry, which enables the processing circuitry to take certain steps to avoid device misbehaviors.

    摘要: A hearing assistance system including a hearing instrument designated as a master device and at least another hearing instrument designated as a slave device. The master device is communicatively coupled to the slave device via a wireless link. The master device has a master clock and generates master time stamps for specified events timed by the master clock. The master time stamps are sent to the slave device via the wireless link. The slave device has a slave clock and generates slave time stamps for specified events timed by the slave clock. The slave clock is adjusted for synchronization to the master clock using the master time stamps and the slave time stamps.
