Abstract
A monitoring system includes one or more wireless nodes forming a wireless mesh network; a user activity sensor including a wireless mesh transceiver adapted to communicate with the one or more wireless nodes using the wireless mesh network; and a digital monitoring agent coupled to the wireless transceiver through the wireless mesh network to request assistance from a third party based on the user activity sensor.
Claims21
A system, comprising:
- one or more wireless nodes forming a wireless network;
- a user activity sensor including an accelerometer and a wireless transceiver adapted to communicate with the one or more wireless nodes using the wireless network;
- and
- a processor analyzing accelerometer data and coupled to the wireless transceiver to request assistance from a third party based on the user activity sensor by distinguishing between falls and other types of normal body movement, the processor initiating a telephone call seeking assistance for the user if the user pushes a help button or if the processor detects a dangerous condition, 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.

A method to monitor a person, comprising:
- capturing and transmitting the person's daily activities over a wireless network;
- determining a pattern associated with the person's daily activities using a statistical recognizer to distinguish between falls and other types of normal body movement, including extracting features from body signature sequences representing one or more motion types and matching a sequence of motions corresponding to the one or more motion types;
- and
- requesting assistance with a telephone call if the person's current activity varies from the pattern or if a dangerous condition is detected or if the user manually requests 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.

A method to monitor a person, comprising:
- capturing and transmitting the person's daily activities over a wireless network;
- determining a pattern associated with the person's daily activities using a statistical recognizer to
- distinguish between falls and other types of normal body movement;
- and
- requesting assistance if the person's current activity varies from the pattern or if a dangerous condition is detected;
- and
- detecting a weakness in left half and right half of the person's body;
- a walking pattern for loss of balance or coordination;
- requesting hands/feet movement in a predetermined pattern and reading accelerometer output in accordance with the predetermined pattern;
- checking whether the person experienced dizziness or headache;
- displaying a text image and asking the person to read back the text image one eye at a time;
- using a speech recognizer to detect confusion, trouble speaking or understanding;
- and/or asking the person if numbness is felt in the body.
