1. A fall detection system designed to be worn or carried by a user, comprising:
- a user device comprising one or more sensors configured to measure movements of the user;
a memory device; and
a processing unit configured to;
operate in a first mode in which the processing unit processes the measured movements to determine if the user has fallen;
detect a first input from the user specifying a start of a user-specified time period, wherein the user-specified time period has a predetermined length during which the user will perform one or more specified exercises and/or movements used to assess fall risk;
operate in a data collection mode in which the processing unit stores a sub-set of the measured movements, which includes only the measured movements obtained during the user-specified time period having the predetermined length, in the memory device;
detect a subsequent input from the user specifying a subsequent start of a subsequent user-specified time period, wherein the subsequent user-specified time period has a subsequent predetermined length during which the user will perform the one or more specified exercises and/or movements used to assess the fall risk;
operate in the data collection mode in which the processing unit stores a subsequent sub-set of the measured movements, which includes only the measured movements obtained during the subsequent user-specified time period having the subsequent predetermined length, in the memory device;
detect a second different input from the user after lapse of the user-specified time period; and
operate in a data analysis mode in which the processing unit processes the sub-set of the measured movements stored in the memory device and the subsequent sub-set of the measured movements stored in the memory device to determine a risk of the user falling.

Abstract
There is provided a fall detection system, comprising a user device comprising one or more sensors for measuring the movements of a user; and the system further comprising a processing unit configured to operate in a first mode in which the processing unit processes the measured movements to determine if the user has fallen and a further mode in which the processing unit processes measured movements obtained during a user-specified time period to determine the risk of the user falling.

15. A method of operating a fall detection system designed to be worn by a user, the method comprising:
-
measuring, with one or more sensors of a user device, movements of the user; operating, with a processing unit of the user device, the system in a first mode in which the measured movements are processed to determine if the user has fallen; detecting, with the processing unit of the user device, a first input from the user specifying a start of a user-specified time period, wherein the user-specified time period has a predetermined length during which the user will perform one or more specified exercises and/or movements used to assess fall risk; operating, with the processing unit of the user device, the system in a data collection mode in which the processing unit stores a sub-set of the measured movements, which includes only the measured movements obtained during the user-specified time period having the predetermined length, in a memory; detecting, with the processing unit of the user device, a subsequent input from the user specifying a subsequent start of a subsequent user-specified time period, wherein the user-specified time period has a subsequent predetermined length during which the user will perform the one or more specified exercises and/or movements used to assess the fall risk; and operating, with the processing unit of the user device, in the data collection mode in which the processing unit stores a subsequent sub-set of the measured movements, which includes only the measured movements obtained during the subsequent user-specified time period having the subsequent predetermined length, in the memory; detecting, with the processing unit of the user device, a second different input from the user after lapse of the user-specified time period; and operating, with the processing unit of the user device, the system in a data analysis mode in which the processing unit processes the stored sub-set of the measured and the stored subsequent sub-set of the measured movements to determine a risk of the user falling. - View Dependent Claims (16)
