Abstract

A tactile visual indicator and methods, apparatuses, and computer program products for controlling a tactile visual indicator are provided. Embodiments include a light source; an electromagnetically inductive wound coil; and a light pipe coupled to a ferromagnetic-metal jacket surrounding the outside of the light pipe. The ferromagnetic-metal jacket is within the wound coil and one end of the light pipe is provided to the light source. The light pipe and the ferromagnetic-metal jacket are configured to move within the wound coil in response to the coil receiving power. Light shining through the light pipe from the light source provides a visual indication of a status and the movement of the light pipe and jacket within the wound coil provides a tactile indication of the status via contact with a user.

Claims

1. A tactile visual indicator, the indicator comprising:

a light source;

an electromagnetically inductive wound coil; and

a light pipe coupled to a ferromagnetic-metal jacket surrounding the outside of the light pipe, the ferromagnetic-metal jacket within the wound coil, one end of the light pipe provided to the light source;

the light pipe and the ferromagnetic-metal jacket configured to move within the wound coil in response to the coil receiving power;

wherein light shining through the light pipe from the light source provides a visual indication of a status and the movement of the light pipe and jacket within the wound coil provides a tactile indication of the status via contact with a user.

2. The indicator of claim 1 further comprising a controller configured to:

regulate power supplied to the light source; and

control the motion of the light pipe and ferromagnetic-metal jacket within the wound coil, wherein controlling the motion of the light pipe and ferromagnetic-metal jacket includes regulating power applied to the wound coil.

3. The indicator of claim 1 further comprising a first buffer coupled to one end of the wound coil and a second buffer coupled to the other end of the wound coil, the first buffer and the second buffer positioned on the wound coil to limit the motion of the light pipe and ferromagnetic jacket within the wound coil.

4. The indicator of claim 1 wherein one end of the light pipe includes a cap, the cap passing through light from the light source.

5. The indicator of claim 1 wherein the light source is a light emitting diode (LED).

6. A method of controlling a tactile visual indicator, the method comprising:

providing, by a controller, a visual indication of a status, wherein providing the visual indication includes regulating power supplied to a light source; and

providing, by the controller, a tactile indication of the status, wherein providing the tactile indication includes regulating power supplied to an electromagnetically inductive wound coil, the wound coil surrounding a light pipe with a ferromagnetic-metal jacket, the light pipe and jacket configured to move within the wound coil in response to the wound coil receiving power, the movement of the light pipe and jacket indicating the status via contact with a user, one end of the light pipe provided to the light source to allow light from the light source to shine through the light pipe.

7. The method of claim 6, wherein regulating the power supplied to the wound coil includes changing, by the controller, the direction of current flowing through the wound coil to indicate a different status.

8. The method of claim 6 wherein a first buffer coupled to one end of the wound coil and a second buffer coupled to the other end of the wound coil are positioned on the wound coil to limit the motion of the light pipe and ferromagnetic jacket within the wound coil.

9. The method of claim 6 wherein one end of the light pipe includes a cap, the cap passing through light from the light source.

10. The method of claim 6 wherein the light source is a light emitting diode (LED).

11. Apparatus for controlling a tactile visual indicator, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions capable of:

providing, by a controller, a visual indication of a status, wherein providing the visual indication includes regulating power supplied to a light source; and

providing, by the controller, a tactile indication of the status, wherein providing the tactile indication includes regulating power supplied to an electromagnetically inductive wound coil, the wound coil surrounding a light pipe with a ferromagnetic-metal jacket, the light pipe and jacket configured to move within the wound coil in response to the wound coil receiving power, the movement of the light pipe and jacket indicating the status via contact with a user, one end of the light pipe provided to the light source to allow light from the light source to shine through the light pipe.

12. The apparatus of claim 11, wherein regulating the power supplied to the wound coil includes changing, by the controller, the direction of current flowing through the wound coil to indicate a different status.

13. The apparatus of claim 11 wherein a first buffer coupled to one end of the wound coil and a second buffer coupled to the other end of the wound coil are positioned on the wound coil to limit the motion of the light pipe and ferromagnetic jacket within the wound coil.

14. The apparatus of claim 11 wherein one end of the light pipe includes a cap, the cap passing through light from the light source.

15. The apparatus of claim 11 wherein the light source is a light emitting diode (LED).

16. A computer program product for controlling a tactile visual indicator, the computer program product disposed upon a non-transitory computer readable storage medium, the computer program product comprising computer program instructions capable, when executed, of causing a computer to carry out the steps of:

providing, by a controller, a visual indication of a status, wherein providing the visual indication includes regulating power supplied to a light source; and

providing, by the controller, a tactile indication of the status, wherein providing the tactile indication includes regulating power supplied to an electromagnetically inductive wound coil, the wound coil surrounding a light pipe with a ferromagnetic-metal jacket, the light pipe and jacket configured to move within the wound coil in response to the wound coil receiving power, the movement of the light pipe and jacket indicating the status via contact with a user, one end of the light pipe provided to the light source to allow light from the light source to shine through the light pipe.

17. The computer program product of claim 16, wherein regulating the power supplied to the wound coil includes changing, by the controller, the direction of current flowing through the wound coil to indicate a different status.

18. The computer program product of claim 16 wherein a first buffer coupled to one end of the wound coil and a second buffer coupled to the other end of the wound coil are positioned on the wound coil to limit the motion of the light pipe and ferromagnetic jacket within the wound coil.

19. The computer program product of claim 16 wherein one end of the light pipe includes a cap, the cap passing through light from the light source.

20. The computer program product of claim 16 wherein the light source is a light emitting diode (LED).
