    Abstract: An ear-worn electronic device comprises a housing configured for deployment in, on or about an ear of a wearer and a power source situated in the housing. A sensor is situated in or on the housing and coupled to the power source. The sensor is configured to generate a sensor signal representative of motion of the wearer’s head and relative motion between the sensor and skin of the wearer’s ear resulting from the wearer’s head motion. A controller is situated in the housing and coupled to the power source and the sensor. The controller is configured to assess a fit of the device using the sensor signal.

    Abstract: A system includes a hearing device comprising a rechargeable power source, power management circuitry, and a first charging interface comprising a first cathode contact and a first anode contact spaced apart from the first cathode contact. A charging module comprises a second charging interface configured to detachably couple with the first charging interface of the hearing device. The second charging interface comprises a second anode contact having a contact surface and a displaceable second cathode contact. An arrangement is configured to displace at least a portion of the second cathode contact above the contact surface to facilitate electrical contact between the first and second cathode contacts prior to electrical contact between the first and second anode contacts. Charging circuitry of the charging module is coupled to the second charging interface and configured to charge the rechargeable power source of the hearing device.

    Abstract: First and second hearing assistance devices each comprise a rechargeable power source and power management circuitry configured to control charging of the power sources. A portable charging unit comprises an interface configured to receive a connector of a power cable or a power and data cable, a rechargeable power source coupled to the interface, first and second charge ports configured to receive the first and second hearing assistance devices, and charging circuitry coupled to the first and second charge ports and to the rechargeable power source of the charging unit. The power management circuitry and the charging circuitry cooperate to partially charge the power sources of the hearing assistance devices at an accelerated charge rate above 1.0C when a state of charge (SoC) of the power sources is within a predetermined SoC range.
