1. A wearable device system for reducing risks associated with birth, the wearable device comprising:
- (a) one or more sensors for generating sensor data indicative of an orientation of an abdomen of a user; and
(b) a processor coupled with the one or more sensors, the processor configured to;
monitor the orientation of the abdomen of the user by processing the sensor data to estimate the orientation of the abdomen of the user;
identify orientation risk values associated with the estimated orientations of the abdomen to produce a time series of identified orientation risk values;
calculate and update a first cumulative risk value by calculating a first moving average for a subset of the time series of identified orientation risk values associated with the estimated orientations of the abdomen, the subset for the first moving average having a first size;
compare the first cumulative risk value to a first threshold; and
output a warning when the first cumulative risk value crosses the first threshold.

17. A system comprising
a processing device; - and
a non-transitory computer-readable medium accessible by the processing device, wherein the processing device is configured to execute logic embodied in the non-transitory computer-readable medium and thereby perform operations comprising; receiving force measurements from a sensor; calculating force changes over time using the received force measurements; determining whether the user is engaged in clinically significant activity based on the calculated force changes and an activity threshold; when the user is determined to not be engaged in clinically significant activity; (a) receiving a recline angle and a sideways tilt angle from a sensor; (b) identifying orientation risk values associated the received recline angle and the received sideways tilt angle; and (c) recording a time series of orientation risk values; when the user is determined to be engaged in clinically significant activity; (a) identifying activity risk values associated with the force changes; and (b) recording a time series of activity risk values; combining the recorded time series of orientation risk values with the recorded time series of activity risk values to generate a continuous time series of risk values; calculating a cumulative risk on a subset of the continuous time series of risk values by calculating a moving average for a subset of the continuous time series of risk values; comparing the cumulative risk to a cumulative risk threshold value; and outputting a warning when the cumulative risk crosses the cumulative risk threshold value. - View Dependent Claims (18, 19, 20)

21. A method for reducing risks associated with birth, the method comprising:
-
receiving sensor data from a sensor coupled with a user; determining whether the user is engaged in activity based on the received sensor data; when the user is determined to not be engaged in activity, monitoring the orientation of the abdomen of the user by processing the sensor data to estimate the orientation of the abdomen of the user; identifying orientation risk values associated with the estimated orientations of the abdomen to produce a time series of identified orientation risk values; calculating and updating a cumulative risk value by calculating a first moving average for a subset of the time series of identified orientation risk values associated with the estimated orientations of the abdomen; comparing the cumulative risk value to a first threshold and a second threshold; and outputting a first warning when the cumulative risk value crosses the first threshold and a second warning when the cumulative risk value crosses the second threshold. - View Dependent Claims (22)

23. A wearable device system for reducing risks associated with birth, the wearable device comprising:
-
one or more sensors for generating force data indicative of an activity of the user; and a processor coupled with the one or more sensors, the processor configured to; monitor the activity of the user by processing the force data to identify force changes in the force data to estimate a vigorousness of the activity of the user; compare the identified force changes to a force change threshold value to determine whether the user is engaged in clinically significant activity; when the user is engaged in clinically significant activity, the processor is configured to identify activity risk values associated with the identified force changes to produce a time series of identified activity risk values; calculate and update a cumulative risk value by calculating a moving average for a subset of the time series of identified activity risk values associated with the identified force changes; compare the cumulative risk value to a threshold; and output a warning when the first cumulative risk value crosses the first threshold. - View Dependent Claims (24, 25, 26, 27)
