    Abstract: A motion-detection-circuit configured to receive an audio-output-signal and a received-motion-signal. The motion-detection-circuit includes a preliminary-motion-detector configured to process the received-motion-signal in order to set a state of a prelim-motion-detected-signal based on the received-motion-signal; and an ADC for providing an ADC-output-signal that is a digital representation of a signal received at an ADC-input-terminal. The motion-detection-circuit also includes a switch configured to connect either (i) an audio-output-receiver or (ii) a motion-signal-receiver-terminal to the ADC-input-terminal based on the state of the prelim-motion-detected-signal. The motion-detection-circuit further includes a digital-motion-detector configured to, based on the state of the prelim-motion-detected-signal, process the ADC-output-signal in order to set a state of a motion-detection-signal; and a digital-audio-processor configured to, based on the state of the prelim-motion-detected-signal, process the ADC-output-signal in order to provide an audio-input-signal for an audio-output-module.

    Abstract: An apparatus comprising an acoustic transducer arrangement configured to transmit at least one acoustic signal and configured to detect a reflection of said at least one acoustic signal, and a controller configured to determine a time-of-flight of the at least one acoustic signal, the controller further configured to determine at least a first value indicative of temperature based on said time-of-flight of the at least one acoustic signal and calibration information indicative of a relationship between time-of-flight and temperature in a space the apparatus is located.
