    Abstract: According to an aspect, there is provided a fall detection apparatus, the fall detection apparatus comprising one or more processing units configured to obtain a first input indicating which one or ones of a plurality of fall detection algorithms have detected a potential fall by the subject, wherein each fall detection algorithm of the plurality of fall detection algorithms is associated with a respective type of fall and detects a potential fall of the associated type by analysing a set of movement measurements for the subject, wherein each respective type of fall has an associated initial state of the subject; obtain a second input indicating the status of the subject prior to the potential fall, wherein the status of the subject is determined by analysing a set of measurements from one or more sensors in the environment of the subject; compare the determined status of the subject prior to the potential fall to the initial state for each type of fall associated with any potential fall indicated in the first input; and output an indication that the subject has fallen if the determined status of the subject matches the initial state of any of the respective types of fall associated with any potential fall indicated in the first input.

    Abstract: 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.

    Abstract: In one embodiment, a fall detection apparatus (12) is presented that detects when a suspected fall event has occurred based on receipt of arm direction information. The fall detection apparatus provides further discrimination of when events involving a subject are suspected fall events, which helps to reduce false alarm rates and encourage continual use of the apparatus.

    Abstract: Techniques are described herein for monitoring activities of organisms, including sleep. In various embodiments, logic (116) may receive, from a first sensor (106) adapted to detect activity in a first area (104), signal(s) indicating activity of an organism. Based on these signal(s), the logic may identify (504) a first time at which the organism transitions into a first state. The logic may later receive (508), from a second sensor (110, 114) adapted to detect activity in a second area (108, 112), signal(s) indicative of activity in the second area. Based on these subsequent signal(s), the logic may identify (510) a second time that is after the first time, determine (512) whether the first sensor provided signal(s) indicative of activity in the first area within another time interval preceding the second time, and selectively store (514) an indication of transition of the organism into a second state based on the determination.

    Abstract: A fall risk of a user is determined by collecting measurements of the motion of the user. A value for a parameter related to the gait of the user is estimated from the measurements. The fall risk for the user is determined from a comparison of the estimated value with a normal value for the parameter determined from motion of the user in which the user is at their normal risk of falling.

    Abstract translation: 通过收集用户运动的测量来确定用户的跌倒风险。 根据测量值估计与用户步态相关的参数的值。 用户的跌倒风险根据用户处于正常风险下降的用户的运动所确定的参数的正常值与正常值的比较来确定。

    Abstract: Presented are concepts for monitoring walker usage by a subject. One such concept obtains movement data comprising values of detected movement of an arm of the subject for a first time period during which the subject is determined to have transferred between first and second locations the first time period. It is determined if the subject used a walker during the first time period based on a measure of variance in the values of detected movement of the subject's arm during the first time period.
