Abstract: A performance measuring system integrated with an article of clothing, the system has a computing unit for coordinating, processing and transmission of sensor data connected to a bus and an antenna. A sensor for measuring performance characteristics is connected to the bus; the bus facilitates transmission and reception of control and data values between the computing unit and the sensor. Also, an antenna is connected to the computing unit for communicating with other computing devices and transmission of sensor data. The other computing devices display the sensor data to a user or forward the sensor data onto another communication media such as the internet or interactive television. A social networking system sharing athletic statistics using a webservice, a personal processing unit connectible to the webservice, and a computing unit having an activity program for at least one sensor. This system has an activity update service integrally associated with the webservice.
