Abstract
Systems and methods are disclosed that monitor movement of a person, or of a vehicle ridden by the person, to determine speed, distance traveled and/or airtime of the person or vehicle. Accelerometer-based sensors, pressure sensors or Doppler sensors may be employed in these systems and methods. A liquid crystal display may attach to the person to display speed, distance traveled and/or airtime.

15. A Doppler-based movement monitoring system, comprising:
-
a Doppler sensor for mounting to a human-powered vehicle and generating a beam of electromagnetic energy through a beam-splitter to strike ground adjacent to the vehicle, the sensor configured to determine Doppler shift of electromagnetic energy reflected from the ground and received through the beam-splitter; and
a processor for processing information from the Doppler sensor to determine speed of the vehicle.

17. A method of determining one or both of speed and distance traveled of a moving person, comprising:
-
sensing one or more accelerations of the person while moving over a surface;
determining, from the accelerations, when the person is in contact with the surface and when the person is not in contact with the surface, to determine one or both of speed and distance traveled of the person.
