Systems And Methods For Managing A Person's Position Based On A Personal Health Factor

A system for automated management of a person's position, comprising:

• at least one sensor configured to generate sensor data associated with a position of the person during a series of (a) pressure-on periods in which the person is in a pressure-on position, and (b) relief periods in which the person is in a relief position;
• and
• a processor coupled to the at least one sensor and configured to:
• determine a personal health factor for the person, wherein the personal health factor is based on health-related information specific to the person;
• receive sensor data from the at least one sensor via wired or wireless communications;
• detect changes in the person's position over time based on the received sensor data;
• and
• for a particular relief period, set a time-off threshold value for the particular relief period by:
• determining a pressure-on value for the particular relief period based on a measured duration of at least one pressure-on period preceding the particular relief period;
• and
• determining a time-off threshold value for the particular relief period as a function of (a) the pressure-on value determined for the particular relief period and (b) the personal health factor for the person;
• measure a duration of the particular relief period based on the received sensor data;
• determine, based on (a) the duration of the particular relief period and (b) the time-off threshold value for the particular relief period, a notification condition;
• and
• generate a notification in response to determining the notification condition.

A method for automated management of a person's position using a wearable sensor device affixed to or carried by the person, the method comprising:

• generating, by at least one sensor provided in the wearable sensor device, sensor data representative of a position of the person during a series of (a) pressure-on periods in which the person is in a pressure-on position, and (b) relief periods in which the person is in a relief position;
• and
• determining, by a processor, a personal health factor for the person, wherein the personal health factor is based on health-related information specific to the person;
• receiving sensor data at the processor via a wired or wireless communication connection with the at least one sensor;
• identifying, by the processor, changes in the person's position over time based on the received sensor data;
• and
• for a particular relief period, setting, by the processor, a time-off threshold value for the particular relief period by:
• determining a pressure-on value for the particular relief period based on a measured duration of at least one pressure-on period preceding the particular relief period;
• and
• determining a time-off threshold value for the particular relief period as a function of (a) the pressure-on value determined for the particular relief period and (b) the personal health factor for the person;
• measuring, by the processor, a duration of the particular relief period based on the received sensor data;
• determining, by the processor, a notification condition based on (a) the duration of the particular relief period and (b) the time-off threshold value for the particular relief period;
• and
• generating, by the processor, a notification in response to determining the notification condition.
