Abstract

A force detection system includes first and second sets of pressure sensors, memory, and a processing module. The first set of pressure sensors are in an insole of a shoe and the second set of pressure sensors are in an outsole of a shoe. The processing module receives first data regarding the first set of pressure sensors and generates a first digital representation of the first data. The processing module also receives second data regarding the second set of pressure sensors and generates a second digital representation of the second data. The processing module also writes the first and second digital representations to the memory.

Claims (41)

1. A method comprises:

obtaining, by a processing module of a force detection system and/or by a processing module of a computing entity, first x, y, and z force component data of a first pressure sensor of the force detection system when active in a shoe;

obtaining, by the processing module of the force detection system and/or by the processing module of the computing entity, second x, y, and z force component data of a second pressure sensor of the force detection system when active in the shoe;

determining, by the processing module of the force detection system and/or by the processing module of the computing entity, magnitude and direction of force traversing through at least a portion of a sole of the shoe based on at least one of the first and second x, y, and z force component data; and

determining, by the processing module of the force detection system and/or by the processing module of the computing entity, force loss of the at least the portion of the sole based on a difference between the first and second x, y, and z force component data.

2. The method of claim 1 further comprises:

the first pressure sensor is affiliated with an insole of the sole; and

the second pressure sensor is affiliated with an outsole of the sole, wherein, from a lateral side view, a front view, and a top view, the first pressure sensor and the second pressure sensor are substantially aligned.

3. The method of claim 2 , wherein the determining the magnitude and the direction of the force traversing through the at least the portion of the sole comprises:

determining the magnitude and the direction of the force traversing through the at least the portion of the sole based on the second x, y, and z force component data.

4. The method of claim 2 further comprises:

determining, by the processing module of the force detection system and/or by the processing module of the computing entity, force loss of the at least the portion of the sole based on a difference between the first and second x, y, and z force component data.

5. The method of claim 1 further comprises:

the first pressure sensor is affiliated with an insole of the sole; and

the second pressure sensor is affiliated with a mat on which a wearer of the shoe stands, wherein the magnitude and the direction of the force traversing through the at least the portion of the sole is based on the second x, y, and z force component data.

6. The method of claim 1 further comprises:

the first and second pressure sensors are affiliated with an insole of the sole; and

determining, by the processing module of the force detection system and/or by the processing module of the computing entity, foot movement within at least a portion of the shoe based on the first and second x, y, and z force component data.

7. The method of claim 6 further comprises:

determining, by the processing module of the force detection system and/or by the processing module of the computing entity, x direction movement of the foot movement based on a difference between the first and second x force components of the first and second x, y, and z force component data.

8. The method of claim 6 further comprises:

determining, by the processing module of the force detection system and/or by the processing module of the computing entity, y direction movement of the foot movement based on a difference between the first and second y force components of the first and second x, y, and z force component data.

9. A Non-transitory computer readable memory comprises: a first memory section that stores operational instructions that, when executed a processing module of a force detection system and/or by a processing module of a computing entity, causes the processing module of the force detection system and/or the processing module of the computing entity to: obtain first x, y, and z force component data of a first pressure sensor of the force detection system when active in a shoe; obtain second x, y, and z force component data of a second pressure sensor of the force detection system when active in the shoe; and a second memory section that stores operational instructions that, when executed the processing module of a force detection system and/or by the processing module of a computing entity, causes the processing module of the force detection system and/or the processing module of the computing entity to: determine magnitude and direction of force traversing through at least a portion of a sole of the shoe based on at least one of the first and second x, y, and z force component data determine force loss of the at least the portion of the sole based on a difference between the first and second x, y, and z force component data.

10. The computer readable memory of claim 9 further comprises:

the first pressure sensor is affiliated with an insole of the sole; and

the second pressure sensor is affiliated with an outsole of the sole, wherein, from a lateral side view, a front view, and a top view, the first pressure sensor and the second pressure sensor are substantially aligned.

11. The computer readable memory of claim 10 , wherein the second memory section further stores operational instructions that, when executed the processing module of a force detection system and/or by the processing module of a computing entity, causes the processing module of the force detection system and/or the processing module of the computing entity to determine the magnitude and the direction of the force traversing through the at least the portion of the sole by:

determining the magnitude and the direction of the force traversing through the at least the portion of the sole based on the second x, y, and z force component data.

12. The computer readable memory of claim 10 , wherein the second memory section further stores operational instructions that, when executed the processing module of a force detection system and/or by the processing module of a computing entity, causes the processing module of the force detection system and/or the processing module of the computing entity to:

determining force loss of the at least the portion of the sole based on a difference between the first and second x, y, and z force component data.

13. The computer readable memory of claim 9 further comprises:

the first pressure sensor is affiliated with an insole of the sole; and

the second pressure sensor is affiliated with a mat on which a wearer of the shoe stands, wherein the second memory section further stores operational instructions that, when executed the processing module of a force detection system and/or by the processing module of a computing entity, causes the processing module of the force detection system and/or the processing module of the computing entity to determine the magnitude and the direction of the force traversing through the at least the portion of the sole based on the second x, y, and z force component data.

14. The computer readable memory of claim 9 further comprises:

the first and second pressure sensors are affiliated with an insole of the sole; and

a third memory section further stores operational instructions that, when executed the processing module of a force detection system and/or by the processing module of a computing entity, causes the processing module of the force detection system and/or the processing module of the computing entity to:

determine foot movement within at least a portion of the shoe based on the first and second x, y, and z force component data.
