Abstract: A method for actuating a gradient coil can include the provision of a target value for a manipulated variable, the output of the manipulated variable according to the target value to the gradient coil, the capture of an actual value of the output manipulated variable, the scaling of the captured actual value taking into consideration a scaling characteristic depending on the target value, and the transformation of the actual value captured in a scaled manner into a digital actual value.

Abstract: A method and an associated configuration transmit data between a hearing device and an external unit. A first data packet is transmitted to the hearing device by the external unit. The first data packet is received by the hearing device and a second data packet is transmitted from the hearing device to the external unit. A predefinable fixed period of time elapses between the end of the receipt of the first data packet and the start of transmission of the second data packet. The external unit thereby “knows” when the first bit of the second data packet is to arrive. This offers the advantage that the reliability of a data transmission is improved. In the case of a packet-oriented data transmission fewer data packet repetitions are required, as a result of which the transmission speed increases.

Abstract: A hearing instrument system with a rechargeable battery or accumulator is optimized for everyday use, in particular for EOL detection, and the performance and service life of the accumulator. A hearing instrument, an accumulator system, and a charging system each have an energy transfer interface and a communication interface. The energy transfer interface and communication interface on the accumulator side can establish an energy transfer link and/or communication link on the charge and hearing instrument side. The accumulator system provides energy to the hearing instrument and transmits state of charge information generated by an accumulator control facility to the hearing instrument by way of the respective communication link. The transmission of the state of charge information enables a reliable state of charge detection in the case of batteries, whose state of charge cannot be identified on their voltage, for instance Li-ion systems with closed-loop controlled voltage.

Abstract: The invention relates to a receiver system for an otological device. The receiver system has an oscillation receiver to receive a carrier signal with a carrier frequency. The receiver system is designed to change a receive frequency for the carrier signal. The receiver system has a frequency regulator which is designed to at least indirectly register the receive frequency and to change the receive frequency for the carrier signal to a predetermined receive frequency and to set it to the predetermined receive frequency. The frequency regulator is connected to the oscillation receiver at least at least indirectly and is designed to generate an excitation signal and to excite the oscillation receiver to oscillate by means of the excitation signal and thus to generate a response oscillation with a response frequency. The frequency regulator is also designed to ascertain the receive frequency depending on the response oscillation.

Abstract: The invention relates to a multi-component hearing aid system, comprising at least one first component that is designed to be disposed on or in the ear of a patient for the purpose of generating and/or amplifying an auditory stimulus and at least one further component which can engage at least partially and/or temporarily in a wireless communication connection via which a data transmission can take place with the first component that is to be worn on or in the ear, wherein circuitry means are included which can place at least one source of interference contained in the hearing aid system at least during the transmission of data into an operating mode in which interference signals are coupled by said at least one source of interference into a receiver involved in the data transmission in a manner that is at least attenuated compared to the normal operating mode.

Abstract: With the date transmission in a hearing device system, overloads are to be avoided and the energy consumption during transmission is to be kept as low as possible. To this end, a transmission method and a corresponding system for the inductive transmission is proposed, in which the receiver returns an item of quality information relating to the received signal back to the transmitter. The transmission power of the transmitter is then dynamically varied as a function of the item of quality information. With unidirectional transmission, the transmitter can obtain an item of distance information relating to the distance of the receiver from the transmitter and thereupon adjust the transmission power accordingly.

Abstract: An especially small operating device for a hearing aid, but one which is nevertheless simple for a user to actuate manually, which still enables a multiplicity of different operating functions in a simple and clear manner is provided. The use of a fingerprint sensor is provided for this purpose, whereby different operating functions are assigned to the individual fingers of the user. Depending on the finger with which the user actuates the fingerprint sensor, different operating functions are initiated.

Abstract: There is described an amplifier for a radio frequency signal for transmitting a transmit signal to an otological apparatus. The amplifier comprises at least one power transistor for switching an output signal. A breaker gap of the power transistor is actively connected to a network such that a power loss converted in the power transistor is at least partially reduced during a switchover into a switched-on state and/or at least during a switchover into a switched-off state. The breaker gap of the at least one transistor is at least indirectly connected in series to a power supply source by way of a choke coil. The amplifier comprises a transmit coil as an output load, with the transmit coil comprising an inductor and being actively connected to the power transistor. The transmit coil is coupled to the choke coil in a transformer-like manner, with the choke coil thus being able to transmit an output power to the transmit coil. The transmit coil can generate a transmit signal from the output power.

Abstract: Structurally simple transmit/receive circuits for hearing devices are to be able to be deployed for higher frequencies as well. It is therefore proposed according to the invention that at least two PIN diodes should be connected in an anti-parallel manner between the receive oscillating circuit and the amplifier connected thereto to protect the amplifier. A capacitance diode can optionally be expanded so that larger component tolerances can be permitted for the circuit.

Abstract: Supplying energy into a hearing apparatus in order to charge its rechargeable battery is to be carried out by way of components, which take up as little space as possible. Components, which are mostly already present, are thus used for the energy supply. Energy is inductively injected into the coil of a receiver, into a data transmission coil or a telephone coil for instance. Alternatively, acoustic energy can also be injected via the receiver or microphone and converted there into electrical energy. Special components need then not be provided for the energy supply process.
