A room floor apparatus 10 comprises one or more tiles 11 for laying on a floor of a room. A detection element is arranged to register one or more pressure patterns on a said one or more tiles 11. The registered pressure patterns are transmitted to a processor 16 via a wire 17. The processor 16 is configured to discriminate between a plurality of pressure patterns and is capable of transmitting a signal to a receiver (18,fig.3) relating to the identified pressure pattern. The receiver (18,fig.3) has a screen (19,fig.3) for displaying a fall alert message. The detection element may be located between the tile and the floor, or embedded in the tile and/or the floor. The detection element may comprise two or more membrane layers functioning as a switch. The detection element may be made of, or include a quantum tunnelling composite pill. The processor 16 may discriminate between footsteps and a fall. |
