Abstract: An equipment maintenance information system includes a detection assembly, a mobile device and a network. The detection assembly is configured to detect a condition of at least one part of a piece of equipment, and the mobile device is communicatively connected to the detection assembly and the network. The mobile device is configured to provide substantially real-time data based upon both an output received from the detection assembly and data received from the network. In one embodiment, the system includes a case that forms a housing for the detection assembly and removably attaches to a variety of mobile devices.

Abstract: Strain gauges are mounted on each crank arm of the bicycle and provide a measure of the torque applied to each crank arm. In a preferred embodiment, strain gauges are mounted on opposite edges of each crank arm, which includes a self-contained power, electrical circuitry, and a wireless transmitter for transmitting the strain measurement information to a main controller. The main controller includes a wireless transceiver for transmitting and receiving data from both the left and right crank arms and external devices. Memory is also included for storing such data for subsequent analysis to determine the individual leg performance of a cyclist during a race or training session.
