摘要： A system and method for refuelling a fuel cell having a fuel reservoir. The system includes a cartridge (1) having a first reservoir (2) for storing fuel for the fuel cell and a refuelling unit adapted to receive a waste liquid from the fuel reservoir of the fuel cell and provide fuel from the first reservoir (2) of the cartridge (1) to the fuel reservoir of the fuel cell. The system further includes a second reservoir for storing the waste liquid from the fuel cell, a cartridge for use with the system, a refuelling unit for use with the system.

摘要： A method of operating a hearing assistive device having a rechargeable battery, and comprises reading battery status data from a battery controller during use of the hearing assistive device, transferring the battery status data wirelessly from the hearing assistive device to a computing device and predicting, in the computing device, a remaining battery time for the rechargeable battery based upon the battery status data received. Once the remaining battery time is predicted, it is compared with a predefined use pattern for hearing assistive device and a user becomes notified if a conflict between the remaining battery time and the predefined use pattern is observed.

摘要： A system, method and computer program are configured to interactively assist a user in evaluating and/or configuring a hearing aid. The system is equipped with a display element, with an input unit and with a processing unit. The environmental situations are shown on the display element. Based on a user input, a selected section of the environmental situation is determined and highlighted. A specific hearing situation is presented on the basis of the selection made by the user. An evaluation scale is displayed, allowing the user to enter a hearing value for a self-assessment of his hearing ability for the specific hearing situation, and the hearing value entered by the user is recorded. The above steps are repeated and hearing values are recorded for different specific hearing situations. Based on the hearing values entered by the user, setting values for the hearing aid are determined.

摘要： The use of the correct, required length of a cable in a hearing aid substantially contributes to the wearing comfort of the hearing aid. At least one ear depiction of an ear is created by a camera. An associated ear geometry is determined on the basis of the ear depiction. The required length of the cable for the hearing aid can in turn be determined by use of the ear geometry.

摘要： A differential delta-sigma-modulator has an integrator including a pair of single-ended amplifiers. A sample clock is driving a first switchable capacitor configuration and a second switchable capacitor configuration at a predetermined switching cycle. The first switchable capacitor configuration is adapted for sampling respective outputs from the pair of single-ended amplifiers on a pair of output sampling capacitors in the first part of the switching cycle. The second switchable capacitor configuration is adapted for charging a common mode capacitor with the average voltage of the voltage sampled by the pair of output sampling capacitors in the second part of the switching cycle. The voltage across the common mode capacitor represents the common mode voltage for the integrator.
