摘要： The disclosure presents a method of operating a switched capacitor voltage converter and a switched capacitor voltage converter, where the switched capacitor voltage converter comprises a power source, a bucket capacitance, an output capacitance with output capacitance terminals to be connected to a load and switches. The power source provides an input voltage and the output capacitance provides an output voltage over the output capacitance terminals. The output voltage is different from the input voltage, i.e higher or lower or of opposite polarity. The switches are configured to provide at least two phases, a bucket capacitance charging phase and a bucket capacitance discharging phase. In case of a voltage up-converter in the bucket capacitance charging phase the bucket capacitance is connected to the power source for charging the bucket capacitance while the bucket capacitance is not connected to the output capacitance. In a voltage down-converter in the bucket capacitance charging phase the bucket capacitance and the output capacitance are connected in series with the power source. In a voltage up-converter in the bucket capacitance discharging phase the bucket capacitance is connected in series with the power source for charging the output capacitance. In a voltage down-converter in the bucket capacitance discharging phase the bucket capacitance and the output capacitance are connected in parallel with each other while being disconnected from the power source. Further, a detection circuit is provided that is configured to monitor the output voltage over the output capacitance terminals and to cause switching of at least one of said switches so as to interrupt charging of the output capacitance when output voltage exceeds a predefined reference voltage.

摘要： The application relates to a binaural hearing assistance system comprising first and second hearing assistance devices adapted for being located at or in left and right ears of a user. The application further relates to a method of operating a binaural hearing assistance system. The object of the present application is to provide an improved binaural hearing assistance system. The problem is solved in that each of the first and second hearing assistance devices comprises a) a first wireless interface comprising first antenna and transceiver circuitry adapted for establishing a first communication link to the respective other hearing assistance device based on near-field communication; b) a second wireless interface comprising second antenna and transceiver circuitry adapted for establishing a second communication link to an auxiliary device based on far-field communication; c) a link control unit operatively coupled to the second antenna and transceiver circuitry and configured to repeatedly provide a second link quality measure indicative of a link quality of the second communication link; wherein the first and second hearing assistance devices are configured to exchange said respective second link quality measures between them via said first and/or second communication links. This has the advantage of providing a robust and flexible system. The invention may e.g. be used for binaural hearing assistance systems, e.g. binaural hearing aid systems, where audio quality and power consumption has to be mutually optimized.
