Abstract: An audio streaming device for streaming an audio signal to at least one hearing assistive device (32). The audio streaming device comprises at least one input transducer (21), an electronic sensor device (28) adapted for sensing gravitational forces acting on the audio streaming device (20), and a transmitter (30) adapted for streaming audio from the at least one input transducer (21) to the at least one hearing assistive device (32). The audio streaming device (20) further comprises a shock protection unit (31) adapted for comparing an output signal from the electronic sensor device (28) to a first threshold value, and ceasing streaming by the transmitter (30) of the audio stream from the at least one input transducer (21), when the output signal from the electronic sensor device (28) exceeds the first threshold value.

Abstract: A hearing assistive device having an antenna component with a common antenna feed with a switching component. The antenna component has a first branch with a first resonance frequency and a second branch with a second resonance frequency. The hearing assistive device switches between a communication state and a wireless charging state. In the communication state a transceiver is connected to the antenna component, and in the wireless charging state a wireless charging unit is connected to the antenna component.

Abstract: Disclosed is a refueling unit for refueling a fuel cell. The refueling unit comprising a fuel cell receiving section and a cartridge receiving section. The refuelling unit is configured to receive through a waste inlet a waste fluid. The refuelling unit further comprises an intermediate fuel reservoir for storing fuel. The refuelling unit is configured to firstly receive in the intermediate fuel reservoir a predetermined amount of fuel from a cartridge and secondly empty the intermediate fuel reservoir and guide said fuel stored therein into the fuel reservoir of a fuel cell connected to the fuel cell receiving section.

Abstract: 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.

Abstract: A hearing aid having a digital processing unit (200) having at least four digital data inputs configured to provide four input signals, at least two digital data outputs configured to provide two output signals, and a calculation unit (100) having at least one switch and at least one first multiplexer configured to route the input signals from the digital data inputs to the digital data outputs. The first configuration of the at least one switch and the at least one first multiplexer provides a complex multiplication of the four input signals representing two complex numbers, and a second configuration of the at least one switch and the at least one first multiplexer provides parallel real multiplication of two pairs of input signals the four input signals representing four real numbers.
