Abstract: The application relates to a portable electronic system comprising a first electronic device and an auxiliary device. The first electronic device comprises a first antenna defining a first spatial direction, and a first wireless unit operationally coupled to the first antenna. The auxiliary device comprises a second antenna defining a second spatial direction, the second antenna comprising a multitude of antenna elements, each defining a specific spatial direction, a second wireless unit operationally coupled to the second antenna, a direction detector configured to provide a direction-signal indicating an estimate of a current value of said second spatial direction relative to a reference direction, and a control unit configured to selectively control the connection of said multitude of antenna elements of the second antenna to said second wireless unit based on said direction-signal from the direction detector.

Abstract: A MEMS microphone assembly includes a MEMS transducer element having a back plate and a diaphragm displaceable relative to the back plate. A bias voltage generator is adapted to provide a DC bias voltage applicable between the diaphragm and the back plate. An amplifier receives an electrical signal from the MEMS transducer element and provides an output signal. The amplifier is adapted to amplify the electrical signal from the MEMS transducer element according to an amplifier gain setting. A processor is adapted to carry out a calibration routine at power-on of the microphone assembly determining information regarding the DC bias voltage and/or the amplifier gain setting.

Abstract: An assembly includes an analog signal processing unit. An analog signal path and an amplifier an automatic gain control unit are coupled to the signal path. Further to the output of the amplified analog signal, a gain information is provided as an analog or digital signal at a gain information output. This information can be used for further processing the signal, e.g., by automatic noise compression or to control further signal processing units.

Abstract: A microphone comprising an automatic bias control providing a better signal quality is proposed. The microphone comprises a bias control circuit that can provide two or more voltages to the microphone's capacitor. The bias control circuit increases the voltage if the collapse frequency is low and decreases the voltage if the collapse frequency is high.
