Patent ID: 7670263

Claim:
A wireless network for generating personal data, current performance data, and training performance tracking data of an athlete, comprising: a heart rate data sensor device that is adapted to be worn on an athlete's chest during mobile athletic activity and is configured to wirelessly transmit a heart rate output that is representative of a current heart rate of the athlete; a speed data sensor device that is adapted to be in a physical relationship with the athlete in which the speed data sensor device moves with the athlete's mobile athletic activity and is configured to receive Global Positioning System (GPS) information, and to wirelessly transmit a speed of movement output that is representative of the current speed of movement of the athlete; a display device comprising a first wireless receiver, wherein the display device is adapted to be worn on the wrist of the athlete and is configured to receive the heart rate output and the speed of movement output using the first wireless receiver, and to display the current heart rate identified by the heart rate data sensor device and the current speed of movement identified by the speed data sensor; and a removable storage device comprising a second wireless receiver, wherein the storage device is adapted to be worn separately from the display device and to be in a physical relationship with the athlete in which the storage device moves with the athlete's mobile athletic activity and is configured to provide one or more functions, the functions including the storage device being configured to receive using the second wireless receiver the current heart rate output from the heart rate data sensor device and the current speed of movement output from the speed data sensor device and to store a log of data representative of the current heart rate and the current speed of movement for tracking the mobile athletic activity for different sets, wherein the storage device is configured to be modularly removable from the wireless network to allow the athlete to choose when to use the wireless network without the functions provided by the storage device.
