20130127636 | WIRELESS SENSOR NETWORK FOR DETERMINING CARDIOVASCULAR MACHINE USAGE - To provide users the ability to track their cardiovascular exercise and determine cardiovascular exercise machine usage, the present system and methods describe an activity tracking platform. The platform includes a wireless sensor configured to monitor a piece of cardiovascular exercise equipment. The sensor can be configured and positioned to monitor a moving part of the exercise equipment, such as the spinning tread of a treadmill or the circular movement of a bike peddle. Responsive to detecting activity, the sensor can associate the data with a specific user and, using a wireless sensor network, transmit the data to a central server. The platform provides the user an associated website, where the user may view historical workout information, current exercise equipment usage at a local gym, or current workout goals. | 05-23-2013 |
