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.
Claims22
A system, comprising:
- one or more wireless nodes forming a wireless mesh network where data hops from one wireless node to another wireless node;
- 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, wherein the digital monitoring agent detects a weakness in left half and right half of the person's body;
- a walking pattern for loss of balance or coordination;
- hand or foot movement in a predetermined pattern based on accelerometer output in accordance with the predetermined pattern;
- feeling of dizziness or headache;
- ability to read text image one eye at a time;
- confusion, trouble speaking or understanding;
- or if numbness is felt in the body.

A method to monitor a person, comprising:
- capturing and transmitting the person's daily activities over a wireless mesh network using mesh network transceivers with data hopping from node to node;
- determining a pattern associated with the person's daily activities;
- 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;
- detecting 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;
- or asking the person if numbness is felt in the body.
