Patent ID: 8054176

Claim:
A data transmission method for use in the transmission of a performance transmitter of a portable user-specific performance monitor by using wireless data transmission that is based on radio-frequency electromagnetic radiation, the method comprising: measuring, by the performance monitor, at least one of a movement and organ system state of the user; detecting whether wireless data transmission capability is available in the performance transmitter by detecting that wireless data transmission capability of the performance transmitter is not available if an inhibiting command is received from a user interface of the performance transmitter when the user prevents the use of wireless data transmission or if a command that inhibits wireless data transmission is received from a predefined communication device to the performance transmitter, and by detecting that wireless data transmission of the performance transmitter is available if a permit command is received from the user interface when the user permits wireless data transmission capability from the performance transmitter or if a command that permits wireless data transmission is received from the predefined communication device to the performance transmitter, when wireless data transmission capability from the performance transmitter to the predefined communication device is available; and storing measuring data into the memory of the performance transmitter and not transmitting measuring data, if wireless data transmission capability is not available, otherwise transmitting the measuring data by using wireless data transmission.
