Patent ID: 8467979

Claim:
A system for providing an athlete with energy related information comprising: a shoe with a plurality of pressure sensors located between the space to be occupied by a wearer's foot and the ground when the shoe is in use, each of the pressure sensors capable of producing an analog electrical signal indicative of the pressure being applied to the sensor; a processing system for processing the analog electrical signals output by the plurality of sensors to provide information related to the wearer's energy efficiency, the processing system comprising: analog-to-digital convertor for converting the analog electrical signals produced by the plurality of sensors into digital electrical signals at a predetermined sampling rate; a processor for processing the digital electrical signals to produce energy efficiency related information; and a display for providing a visual display of the energy efficiency related information; wherein the processor is adapted to process the digital signals to identify, with respect to a period of time during which the shoe is in contact with the ground or other surface, the start of the landing phase, the end of the landing phase and start of the launching phase, and the end of the launching phase.
