Abstract
A monitoring system includes a shoe and a sole integrated into the shoe. The monitoring system also includes a connection mechanism attached to an underside of the sole and is shaped to connect the sole to a pedal. A pressure sensor is incorporated into the shoe that senses a force exerted on the pedal when the shoe is connected to the pedal through the connection mechanism.
Claims20
A method for monitoring pedaling, comprising:
- determining a force applied to a pedal by a shoe during a pedal stroke, wherein determining the force includes measuring a change in distance of a first plate relative to a second plate of a capacitor force sensor located in a shoe;
- determining movement information of the shoe using an accelerometer located in the shoe;
- and
- using the movement information, modifying the determined force to correct for a motion artifact of the shoe during the pedal stroke.

A method for monitoring pedaling, comprising:
- determining a force value for a force applied to a pedal by a shoe using a capacitive force sensor located in a shoe above a cleat configured to connect to the pedal;
- determining a direction of the force by measuring a change in distance between two plates of the capacitive force sensor relative to a baseline distance, the change in distance being a result of the force applied to the pedal during a pedal stroke;
- determining if a motion artifact exists in the force value based on movement information received from an accelerometer in the shoe;
- and
- if the motion artifact exists, modifying the force value to correct for the motion artifact.

A pedal stroke monitoring system, comprising:
- a shoe including a sole;
- a connection mechanism attached to an underside of the sole, wherein the connection mechanism is shaped to connect the sole to a pedal;
- a pressure sensor including a first plate and a second plate spaced apart from the first plate to form a capacitor, wherein the pressure sensor is incorporated within the sole of the shoe that senses a force exerted on the pedal when the shoe is connected to the pedal through the connection mechanism, wherein the first plate is located above the second plate;
- and
- an accelerometer that measures a motion of the shoe in at least three directions.
