Abstract

A system including: a seat post; a user interface operatively connected with the seat post, the user interface configured for receiving instructions associated with a height of the seat post and for communicating received instructions to at least one controller coupled with a motive source of the seat post; and a valve assembly in communication with the motive source, the valve assembly regulating fluid flow within a variable finite positioning seat post height mode in response to a translation of the received instructions by the motive source.

Claims

1. A system comprising:

a seat post;

a user interface operatively connected with said seat post, said user interface configured for receiving instructions associated with a height of said seat post and for communicating said instructions to at least one controller coupled with a motive source of said seat post; and

a valve assembly in communication with said motive source, said valve assembly regulating fluid flow within a variable finite positioning seat post height mode in response to a translation of said instructions by said motive source, wherein said valve assembly comprises;

two sets of check valves configured for at least one of opening and closing in response to said translation, said two sets of check valves positioned, relative to each other, in a series, and opposed to each other, such that one-way only movement is achieved in response to said translation.

2. The system of claim 1, wherein said user interface is remote from said valve assembly.

3. The system of claim 2, wherein said user interface comprises at least one of a GUI, button, dial, smart phone, and lever.

4. The system of claim 1, wherein a rate of said opening and said closing of said two sets of check valves is proportional to a real-time displacement measurement, wherein said real-time displacement measurement is based on a measured difference between a seat post height position instruction of said instructions and an actual seat post height of said seat post.

5. The system of claim 1, further comprising:

a displacement sensor coupled with said at least one controller, said displacement sensor configured for measuring a displacement between a seat post height position instruction and an actual seat post height of said seat post.

6. The system of claim 5, wherein said displacement sensor is a pressure sensor.

7. The system of claim 1, wherein said user interface comprises:

at least one activation button configured for activating a pre-programmed seat post position, wherein said at least one controller comprises said pre-programmed seat post position.

8. The system of claim 1, further comprising:

a motor output shaft coupled with said motive source and internal to said seat post, said motor output shaft configured for rotating in response to said translation; and

a cam coupled with said motor output shaft and said valve assembly and internal to said seat post, said cam configured for moving in response to said rotating of said motor output shaft and configured for at least one of seating and unseating at least one check valve ball set.

9. The system of claim 1, wherein said at least one controller comprises:

a proportional-integral-derivative controller.

10. The system of claim 1, further comprising:

a switch coupled with said seat post, said switch configured for enabling a reprogramming of said valve assembly to operate in either an infinite positioning seat post height mode or said finite positioning seat post height mode.

11. The system of claim 1, further comprising:

a voice activated audio detection module coupled with said seat post, said voice activated audio detection module configured for receiving audible position instructions, translating said audible position instructions, and transmitting translated audible position instructions to said at least one controller, such that an instruction for a desired position for said seat post is received at said at least one controller.

12. The system of claim 1, further comprising:

a voice activated audio detection module configured for receiving an audible instruction.

13. The system of claim 1, wherein said at least one controller comprises:

an input parameter receiver configured for receiving an input;

a threshold determiner coupled with said input parameter receiver, said threshold determiner configured for determining whether or not a predetermined threshold has been exceeded;

a comparator coupled with said threshold determiner, said comparator configured for comparing said input and said threshold; and

a signal generator coupled with said comparator, said signal generator configured for generating a signal based upon said comparing.

14. The system of claim 13, wherein said input is associated with a physiological factor relating to a rider of a vehicle which includes said seat post.

15. A system comprising:

a seat post;

a user interface operatively connected with said seat post, said user interface to receive instructions associated with a height of said seat post and to communicate the received instructions to at least one controller coupled with a motive source of said seat post;

at least one power connector positioned at an upper end of a lower post, said at least one power connector located to enable power to be received at said seat post; and

a valve assembly in communication with said motive source, said valve assembly regulating fluid flow within a variable finite positioning seat post height mode in response to a translation of said received instructions by said motive source.

16. The system of claim 15, wherein said user interface is remote from said valve assembly.

17. The system of claim 15, wherein said user interface comprises at least one of a GUI, button, dial, smart phone, and lever.

18. The system of claim 15, wherein said user interface comprises:

at least one activation button configured for activating a pre-programmed seat post position, wherein said at least one controller comprises said pre-programmed seat post position.

19. The system of claim 15, wherein said user interface comprises:

a voice activated audio detection module configured for receiving an audible instruction.

20. A system comprising:

a seat post;

a user interface operatively connected with said seat post, said user interface configured for receiving instructions associated with a height of said seat post and for communicating received instructions to at least one controller coupled with a motive source of said seat post;

a valve assembly in communication with said motive source, said valve assembly regulating fluid flow within a variable finite positioning seat post height mode in response to a translation of said received instructions by said motive source;

a motor output shaft coupled with said motive source and internal to said seat post, said motor output shaft configured for rotating in response to said translation; and

a cam coupled with said motor output shaft and said valve assembly and internal to said seat post, said cam configured for moving in response to said rotating of said motor output shaft and configured for at least one of seating and unseating at least one check valve ball set.

21. The system of claim 20, wherein said user interface is remote from said valve assembly.

22. The system of claim 20, wherein said user interface comprises at least one of a GUI, button, dial, smart phone, and lever.

23. The system of claim 20, wherein said user interface comprises:

at least one activation button configured for activating a pre-programmed seat post position, wherein said at least one controller comprises said pre-programmed seat post position.
