Abstract: A thermal energy extraction assembly is disclosed, the thermal energy extraction assembly is configured to extract heat and/or cold from a thermal energy distribution grid. The assembly may include a connection circuit connecting the assembly to the grid; a first heat exchanger configured to exchange heat from a heating circuit to the grid; a second heat exchanger configured to extract heat from the grid to a cooling circuit; and a plurality of heat pumps each having a condenser side connected to the heating circuit and an evaporator side connected to the cooling circuit, the heat pumps being configured to pump heat from the cooling circuit to the heating circuit.

Abstract: A mobile communications terminal configured to handle bi-directional voice calls is provided that includes a microphone means, a sound buffer, a loudspeaker means, a positioning means and a processing means. The microphone means is configured to register sound data to be sent out and the loudspeaker means is configured to generate acoustic signals based on incoming sound data. The positioning means is configured to calculate position data reflecting an estimated geographic position of the terminal based on received satellite signals. The processing means is configured to handle surveillance commands and user-generated commands and, in response thereto, control the microphone means to register sound data and cause repeated storage of the sound data in the sound buffer and originate an alarm message, which is adapted to provide at least one predefined recipient with access to the stored sound data and position data generated by the terminal.
