Abstract
A system for a footwear sole component to control an incline in between a footbed and an outsole. An incline adjuster is positioned between the footbed and the outsole. The incline adjuster has a polymeric housing having a first fluid chamber, a second fluid chamber, and a fluid transfer channel; a controller having a processor, a memory, an inertial measurement unit (IMU), and a low energy wireless communication module. The controller determines whether forces from a wearer foot on the first fluid chamber and on the second fluid chamber are creating a pressure within the first fluid chamber that is higher than a pressure within the second fluid chamber, or vice versa.
Claims8
A system for a footwear sole component to control an incline in between a footbed and an outsole comprising:
- an incline adjuster positioned between the footbed and the outsole, the incline adjuster comprising:
- a polymeric housing having a first fluid chamber, a second fluid chamber, and a fluid transfer channel in fluid communication between the first fluid chamber and the second fluid chamber;
- a controller comprising a processor, a memory, an inertial measurement unit (IMU), and a low energy wireless communication module, wherein:
- the memory stores instructions that may be executed by the processor,
- the processor executes instructions stored by memory and/or stored in the processor,
- the IMU comprises an accelerometer and a gyroscope, wherein using data from the accelerometer and the gyroscope, the controller determines if the outsole is in a step portion of a gait cycle and in contact with the ground;
- and
- the low energy wireless communication module communicates information or instructions between the memory, processor, or IMU;
- and
- the controller determines whether forces from a wearer foot on the first fluid chamber and on the second fluid chamber are creating a pressure within the first fluid chamber that is higher than a pressure within the second fluid chamber, or vice versa;
- and
- based on the data from the accelerometer and the gyroscope and the determined pressures of the first and second fluid chambers, the controller adjusts the pressures of the fluid chambers.
