Abstract

An energy harvesting switch is disclosed. The energy harvesting switch includes a magnet, a coil, and a mechanical switch. The manipulation of the mechanical switch causes the magnet to move with respect to the coil and generate an amount of energy. The energy harvesting switch also includes a transmitter configured to use the generated amount of energy to transmit a signal to at least one component coupled with a vehicle, the signal configured to cause a change to at least one characteristic of the at least one component.

First claim

What is claimed is:

1. An energy harvesting system and remote digital switch assembly comprising:
a remote digital switch coupled to a vehicle, said remote digital switch provided at a location within said vehicle such that a user of said vehicle is able find and manipulate said remote digital switch while keeping one hand on a control surface of said vehicle, said remote digital switch further configured to enable said user of said vehicle to manipulate said remote digital switch without requiring said user of said vehicle to view an in-vehicle infotainment (IVI) system of said vehicle; and
an energy harvesting system integrated with said remote digital switch, said energy harvesting system comprising:
a magnet;
a coil;
a mechanical switch, wherein manipulation of said mechanical switch causes said magnet to move with respect to said coil and generate an amount of energy; and
a transmitter coupled with said mechanical switch, said transmitter configured to use said generated amount of energy to transmit a signal to at least one component coupled with a said vehicle, said signal configured to cause a change to at least one characteristic of said at least one component;

wherein said remote digital switch further comprises:
a receiver to receive a wireless message via a wireless protocol; and
a memory powered by a wireless protocol, said memory configured to store said signal for said at least one component coupled with said vehicle, wherein said memory is an erasable programmable read-only memory (Eprom).

2. The energy harvesting system and remote digital switch assembly of claim 1 , wherein said signal configured to cause said change to at least one characteristic of said at least one component is selected from a group of changes consisting of: at least one damping characteristic of at least one active damping component, a damping mode of a suspension of said vehicle, a sway bar, a ride height, and an activation/deactivation of an accessory.

3. The energy harvesting system and remote digital switch assembly of claim 1 , further comprising:
said transmitter to transmit said signal to a suspension controller for said vehicle.

4. The energy harvesting system and remote digital switch assembly of claim 1 , further comprising:
said transmitter to transmit said signal to electronics embedded or incorporated as part a stand-alone active, or semi-active shock absorber.

5. The energy harvesting system and remote digital switch assembly of claim 1 , further comprising:
said transmitter to transmit said signal to said in-vehicle infotainment (IVI) system of said vehicle.

6. The energy harvesting system and remote digital switch assembly of claim 1 , wherein said signal is encrypted.

7. The energy harvesting system and remote digital switch assembly of claim 1 , wherein said signal is a near field communication (NFC) signal.

8. The energy harvesting system and remote digital switch assembly of claim 1 , further comprising:
a housing for containing said magnet, said coil, said mechanical switch, and said transmitter; said housing comprising:
a form factor configured to be held in a human hand; and
a location of said mechanical switch on said housing such that when said housing is held in said human hand, said mechanical switch is accessible to at least one digit of said human hand.

9. The energy harvesting system and remote digital switch assembly of claim 1 , further comprising:
a housing for containing said magnet, said coil, said mechanical switch, and said transmitter; said housing comprising:
a form factor configured to be mounted to a portion of a vehicle accessible to said user of said vehicle; and
a location of said mechanical switch on said housing such that when said housing is mounted with said portion of said vehicle, said mechanical switch is accessible to said user of said vehicle.

10. An energy harvesting system and suspension changing switch comprising:
a suspension changing switch coupled to a vehicle, said suspension changing switch provided at a location within said vehicle such that a user of said vehicle is able find and manipulate said suspension changing switch while keeping one hand on a control surface of said vehicle, said suspension changing switch further configured to enable said user of said vehicle to manipulate said suspension changing switch without requiring said user of said vehicle to view an in-vehicle infotainment (IVI) system of said vehicle; and
an energy harvesting system integrated with said suspension changing switch, said energy harvesting system comprising:
a magnet;
a coil; and
a transmitter to use said generated amount of energy to transmit a suspension signal to at least one active damping component located on said vehicle, said suspension signal configured to change at least one damping characteristic of said at least one active damping component;
wherein said remote digital switch further comprises:
a receiver to receive a wireless message via a wireless protocol; and
a memory powered by a wireless protocol, said memory configured to store said signal for said at least one component coupled with said vehicle,

wherein said memory is an erasable programmable read-only memory (Eprom).

11. The energy harvesting system and suspension changing switch of claim 10 , wherein said suspension signal is configured to change said at least one active damping component to a firmest setting.

12. The energy harvesting system and suspension changing switch of claim 10 , further comprising:
said transmitter to transmit said suspension signal to a suspension controller for said vehicle, said suspension signal configured to cause said suspension controller to change a damping mode of said at least one active damping component.

13. The energy harvesting system and suspension changing switch of claim 12 , wherein said suspension signal is configured to cause said suspension controller to change said damping mode of said at least one active damping component to a firmest setting.

14. The energy harvesting suspension changing switch of claim 10 , wherein said suspension signal includes an authentication signal.

15. The energy harvesting system and suspension changing switch of claim 12 , wherein said suspension signal is a near field communication (NFC) signal.

16. The energy harvesting system and suspension changing switch of claim 12 , further comprising:
a housing for containing said magnet, said coil, said mechanical switch, and said transmitter; said housing comprising:
a form factor configured to be held in a human hand; and
a location of said mechanical switch on said housing such that when said housing is held in said human hand, said mechanical switch is accessible to at least one digit of said human hand.

17. The energy harvesting system and suspension changing switch of claim 10 , further comprising:
a housing for containing said magnet, said coil, said mechanical switch, and said transmitter; said housing comprising:
a form factor configured to be mounted to a portion of a vehicle accessible to said user of said vehicle; and
a location of said mechanical switch on said housing such that when said housing is mounted to said portion of said vehicle, said mechanical switch is accessible to said user of said vehicle.
