Apparatus, systems and methods for removing debris from a surface

1. A method for debris removal from a surface, the method comprising:

providing power to a conductive memory wire that is secured to a moveable portion of a two-position snap spring,

where in response to providing the power to the conductive memory wire, a length of the conductive memory wire decreases, and

where in response to the decreasing length of the conductive memory wire, the moveable portion of the two-position snap spring is pulled from an extended position to a retracted position; and

removing power from the conductive memory wire,

where in response to removing the power to the conductive memory wire, the moveable portion of the two-position snap spring moves from the retracted position to the extended position, and

where in response to the moving of the moveable portion of the two-position snap spring from the retracted position to the extended position, an energy is generated and transferred to the surface that dislodges the debris from the surface.

2. The method of claim 1 , wherein a heating of a material of the conductive memory wire when the power is provided causes a shrinking of the material, and wherein the shrinking of the material reduces the length of the conductive memory wire.

3. The method of claim 1 , wherein a cooling of a material of the conductive memory wire when the power is not provided causes an expansion of the material, and wherein the expansion of the material increases the length of the conductive memory wire.

4. The method of claim 1 , further comprising:

actuating an actuator to engage a lever arm to push the moveable portion of the two-position snap spring,

wherein the lever arm pushes the moveable portion of the two-position snap spring from the retracted position to the extended position.

5. The method of claim 1 , further comprising:

repeatedly providing and removing the power,

where in response to repeatedly providing and removing the power, the moveable portion of the two-position snap spring repeatedly moves between the retracted position and the extended position, thereby generating a vibratory energy that is transferred to the surface that dislodges the debris.

6. The method of claim 1 , wherein the surface further comprises a surface of a signal transmitting/receiving (STR) device, and the method further comprising:

impacting said surface with the moveable portion of the two-position snap spring, and where in response to the impact of the moveable portion of the two-position snap spring on the STR device, an impact energy is generated that is transferred to the surface that dislodges the debris from the surface of the STR device.

7. The method of claim 1 , further comprising:

sensing an accumulation of the debris on the surface,

where in response to sensing the accumulation of the debris on the surface, the power is provided and removed from the conductive memory wire.

8. The method of claim 1 , further comprising:

periodically generating a signal from a timer,

where in response to generating the signal from the timer, the power is provided and removed from the conductive memory wire.

9. The method of claim 1 , further comprising:

receiving a signal at an interface device,

where in response to receiving the signal at the interface device, the power is provided and removed from the conductive memory wire.

10. The method of claim 3 , wherein increasing the length of the conductive memory wire pushes the moveable portion of the two-position snap spring from the retracted position to the extended position.

11. The method of claim 9 , wherein the signal is generated at a set top box.

12. The method of claim 9 , wherein the signal is generated at a remote device.

13. The method of claim 9 , wherein the signal is generated at a service center.
