Patent Images
1. A system, comprising:
- one or more sensors mounted on a patient;
a wireless transceiver to communicate with a remote station connected to a telephone communication network; and
a processor coupled to the sensor and the wireless transceiver to request assistance if the processor detects a fall by the patient using body signature sequences and automatically requests assistance for the patient using a telephone, and wherein the processor also accepts a physical patient actuation with a button to request assistance, and wherein sequences of human motions are classified into groups of similar postures represented by model-states with a posture model depicting inter-relationships among model-states.

11. A method to monitor a person, comprising:
-
capturing motions from the person using a wearable device worn by the person; processing sensor outputs on a processor to determine body signature sequences; determining a body pattern associated with a dangerous condition from the sensor outputs; and requesting assistance through a telephone call if a dangerous condition is detected, and wherein sequences of human motions are classified into groups of similar postures represented by model-states with a posture model depicting inter-relationships among model-states. - View Dependent Claims (12, 13, 14)

15. A method of automatically requesting assistance for a mobile patient, comprising:
-
attaching a mobile device with one or more accelerometers on the patient to detect patient motion; processing accelerometer outputs on a processor; determining a fall based on detected patient motion; and automatically requesting assistance from the mobile device on behalf of the patient with a telephone call if help is needed and allowing the patient to manually push a button to request help, and wherein sequences of human motions are classified into groups of similar postures represented by model-states with a posture model depicting inter-relationships among model-states. - View Dependent Claims (16, 17, 18, 19)

20. A method to provide personal emergency response for a patient, comprising:
-
wearing a mobile device with a help button and at least one or more accelerometers on the patient to detect patient motion; determining a fall based on detected motions including one or more changes in height and one or more accelerations associated with movements by the patient; waiting for a predetermined period to detect if the patient can recover from the fall and automatically requesting assistance with a telephone call if the patient is unable to recover from the fall; and requesting assistance if the patient pushes the help button, and wherein sequences of human motions are classified into groups of similar postures represented by model-states with a posture model depicting inter-relationships among model-states. - View Dependent Claims (21, 22, 23)
