Activity monitoring system and method for transmitting information for activity monitoring

A method for transmitting information for activity monitoring by an occupancy sensor device in an activity monitoring system comprising an activity sensor device worn by an individual, one or more occupancy sensor devices, and an activity monitoring server, the method comprising:

• receiving from the activity sensor device activity classification information and the individual's identification information obtained by detecting a physical activity of a user from a connection-established activity sensor device by using a first propagation;
• and
• transmitting the activity classification information and the individual's identification information along with occupancy information to the activity monitoring server by using a second propagation,
• wherein the activity sensor device transmits the activity classification information and the individual's identification information having a first power or a second power,
• wherein the first power is less than the second power, and
• when the activity sensor device transmits the activity classification information and the individual's identification information to the one or more occupancy sensor devices then the activity sensor device only transmits the activity classification information and the individual's identification information to the one or more occupancy sensor devices having the first power.

A method for transmitting information for activity monitoring by an activity sensor device in an activity monitoring system comprising the activity sensor device worn by an individual, one or more occupancy sensor devices, and an activity monitoring server, the method comprising:

• detecting an individual's activity and classifying the detected signal;
• generating activity classification information by using the classified signal;
• establishing a connection to the one or more occupancy sensor devices;
• and
• transmitting the generated activity classification information and the individual's identification information to the connection-established occupancy sensor devices by using a first propagation with a short transmission range, so that the activity classification information and the individual's identification information can be transmitted along with occupancy information to the activity monitoring server,
• wherein the activity sensor device transmits the generated activity classification information and the individual's identification information to the one or more occupancy sensor devices or the activity monitoring server, and
• wherein the activity sensor device transmits the generated activity classification information and the individual's identification information to the one or more occupancy sensor devices having a first power,
• wherein the activity sensor device transmits the generated activity classification information and the individual's identification information to the activity monitoring server having a second power, and
• wherein the first power is less than the second power.

An activity monitoring system comprising:

• an activity sensor device configured to detect an individual's physical activity, classify the detected physical activity, and transmit activity classification information as a result along with the individual's identification information;
• one or more occupancy sensor devices configured to receive the activity classification information and the individual's identification information from the activity sensor device, and transmit the received information along with occupancy information;
• and
• an activity monitoring server configured to manage the activity classification information, the occupancy information, and the individual's identification information received from the occupancy sensor devices,
• wherein the activity sensor device transmits the activity classification information and the individual's identification information at a first power and a second power, and
• where the activity sensor only transmits the activity classification information and the individual's identification information at the first power after a connection is established between the activity sensor device and the one or more occupancy sensor devices.
