Abstract
One embodiment relates to computer implemented method comprising: controlling an active reflected wave detector to measure wave reflections from an environment to receive measured wave reflection data that is obtained by the active reflected wave detector; determining an occupancy level indicative of how many people are present in the environment; and controlling, in dependence on the occupancy level, a fall detector that is operable to detect whether a person in the environment has fallen based on the measured wave reflection data.
Claims18
A computer implemented method comprising:
- controlling an active reflected wave detector to measure wave reflections from an environment to receive measured wave reflection data that is obtained by the active reflected wave detector;
- determining an occupancy level indicative of how many people are present in the environment;
- and
- controlling, in dependence on the occupancy level, a fall detector that is operable to detect whether a person in the environment has fallen based on the measured wave reflection data, wherein if the occupancy level indicates that only a single person is present in the environment, the method comprises controlling the fall detector to detect whether the single person has fallen based on the measured wave reflection data,
- wherein the controlling comprises, if the occupancy level indicates that multiple people are present in the environment, controlling the fall detector to any of:
- prevent commencement of a fall detection process performed by the fall detector;
- abort a fall detection process performed by the fall detector;
- or
- prevent the issuance of a fall detection alert in response to the fall detector detecting that a person in the environment has fallen.

A non-transitory computer-readable storage medium comprising instructions which, when executed by a processor of a fall detection device, cause the processor to:
- control an active reflected wave detector to measure wave reflections from an environment to receive measured wave reflection data that is obtained by the active reflected wave detector;
- determine an occupancy level indicative of how many people are present in the environment;
- and
- control, in dependence on the occupancy level, a fall detector that is operable to detect whether a person in the environment has fallen based on the measured wave reflection data, wherein if the occupancy level indicates that only a single person is present in the environment, the method comprises controlling the fall detector to detect whether the single person has fallen based on the measured wave reflection data,
- wherein the control comprises, if the occupancy level indicates that multiple people are present in the environment, controlling the fall detector to any of:
- prevent commencement of a fall detection process performed by the fall detector;
- abort a fall detection process performed by the fall detector;
- or
- prevent the issuance of a fall detection alert in response to the fall detector detecting that a person in the environment has fallen.

- wherein the control comprises, if the occupancy level indicates that multiple people are present in the environment, controlling the fall detector to:
- prevent commencement of a fall detection process performed by the fall detector;
- abort a fall detection process performed by the fall detector;
- or
- prevent the issuance of a fall detection alert in response to the fall detector detecting that a person in the environment has fallen.
