US Patent 11341834 Fall detection

Proposed are concepts for distinguishing between fall events and non-fall-events for different sub-groups of subjects within a monitored group (i.e. monitored population) of subjects. It is proposed that an entire group/population of monitored subjects may be partitioned into sub-groups, each sub-group consisting of a plurality of members (i.e. subjects) having a certain property value or characteristic unique to that group. A respective decision value may be determined for each sub-group, wherein the decision value for a sub-group takes account of a previously obtained false fall detection rate for that sub-group.
