Personal emergency response (PER) system

1. A method of automatically requesting assistance for a patient, comprising:

verbally communicating with a user through a base unit;

wearing a mobile device with a plurality of different sensors on the patient to detect patient motion, wherein the mobile device transmits data to the base unit, wherein the patient motions form a sequence of elemental motions;

identifying each elemental motion of a sequence of elemental motions of the accelerometer; and

identifying the activity of the patient, comprising matching the sequence of identified elemental motions with a library of stored sequences of elemental motions, wherein each stored sequence of elemental motions corresponds with an activity; and

determining if a fall has occurred and requesting help through the base unit without a user pressing a button to call for help.

2. The method of claim 1 , comprising determining a location of the mobile device.

3. The method of claim 1 , comprising providing an indoor location determination system based on WiFi or Bluetooth to supplement a global positioning system (GPS).

4. The method of claim 1 , comprising estimating an indoor location of the mobile device based on a radio frequency transmission.

5. The method of claim 1 , comprising distinguishing between falls and other types of normal body movement.

6. The method of claim 1 , comprising notifying an emergency service for assistance automatically without a user pressing a button to call for help.

7. The method of claim 1 , comprising detecting a fall, waiting for a predetermined period before sending an alert to a call center which contacts the patient and sending local emergency services if needed.

8. The method of claim 1 , comprising capturing movement activities and comparing the movement activities to fall patterns and determining if a fall has occurred.

9. The method of claim 1 , comprising sending fall alert data and location to a call center.

10. The method of claim 9 , wherein the call center calls a user on the mobile device and sends help as needed to a current location for the mobile device.

11. The method of claim 10 , wherein the mobile device sends accelerometer pattern matching workload to a remote server to conserve battery power.

12. A method of automatically requesting assistance for a patient, comprising:

verbally communicating with a user through a base unit;

wearing a mobile device with a plurality of different sensors on the patient to detect patient motion, wherein the mobile device transmits data to the base unit;

identifying each elemental motion by:

generating an acceleration signature based on sensed acceleration of the device;

matching the acceleration signature with at least one of a plurality of stored acceleration signatures, wherein each stored acceleration signatures corresponds with a type of motion;

identifying the type of motion of the device based on the matching of the acceleration signature with the stored acceleration signature; and

determining if a fall has occurred and requesting help through the base unit without a user pressing a button to call for help.

13. A method of automatically requesting assistance for a patient, comprising:

verbally communicating with a user through a base unit;

wearing a mobile device with a plurality of different sensors on the patient to detect patient motion, wherein the mobile device transmits data to the base unit;

refining identification of the activity, comprising analyzing timing of the identified activity, and

determining if a fall has occurred and requesting help through the base unit without a user pressing a button to call for help.

14. A method of automatically requesting assistance for a patient, comprising:

verbally communicating with a user through a base unit;

wearing a mobile device with a plurality of different sensors on the patient to detect patient motion, wherein the mobile device transmits data to the base unit;

refining identification of the activity, comprising analyzing at least one identified location of the identified activity; and

determining if a fall has occurred and requesting help through the base unit without a user pressing a button to call for help.

15. A method of automatically requesting assistance for a patient, comprising:

verbally communicating with a user through a base unit;

wearing a mobile device with a plurality of different sensors on the patient to detect patient motion, wherein the mobile device transmits data to the base unit;

refining identification of the activity, comprising analyzing a rate of change of a location of the patient; and

determining if a fall has occurred and requesting help through the base unit without a user pressing a button to call for help.

16. A method of automatically requesting assistance for a patient, comprising:

verbally communicating with a user through a base unit;

wearing a mobile device with a plurality of different sensors on the patient to detect patient motion, wherein the mobile device transmits data to the base unit;

refining identification of the activity, comprising analyzing patterns of a plurality of identified activities; and

determining if a fall has occurred and requesting help through the base unit without a user pressing a button to call for help.

17. A method of automatically requesting assistance for a patient, comprising:

verbally communicating with a user through a base unit;

wearing a mobile device with a plurality of different sensors on the patient to detect patient motion, wherein the mobile device transmits data to the base unit;

identifying a behavior of the object by:

identifying each activity of a sequence of activities of the patient; and

identifying the behavior of the patient, comprising matching the sequence of identified activities of the object with a stored sequences of activities, wherein each stored sequence of activities corresponds with an identified behavior; and

determining if a fall has occurred and requesting help through the base unit without a user pressing a button to call for help.

18. A method of automatically requesting assistance for a patient, comprising:

verbally communicating with a user through a base unit;

wearing a mobile device with a plurality of different sensors on the patient to detect patient motion, wherein the mobile device transmits data to the base unit;

identifying changes in at least one behavior of the patient; and

determining if a fall has occurred and requesting help through the base unit without a user pressing a button to call for help.

19. The method of claim 18 , comprising analyzing timing of the identified activity, at least one identified location of the identified activity, a rate of change of a location of the patient.

20. The method of claim 18 , comprising

analyzing patterns of a plurality of identified activities; and

identifying a behavior of the object by:

identifying each activity of a sequence of activities of the patient; and

identifying the behavior of the patient, comprising matching the sequence of identified activities of the object with a stored sequences of activities, wherein each stored sequence of activities corresponds with an identified behavior.
