PERFORMANCE MONITORING APPARATUS

摘要

A portable performance monitoring module comprising a signal receiver, a processor for generating and outputting performance data, and a communication interface for facilitating data communication with a portable telecommunications device. The performance monitoring module is arranged to communicate with the portable telecommunications device via the communication interface upon receipt of requests from the portable telecommunications device. This module is adapted for cooperative operation with a general power telecommunications device to expand its processing and display power while maintaining a low cost simple design and compactness.
