Abstract

An implementation of systems, devices and methods for a sensor to find a hidden element behind a surface are provided. The sensor includes a housing with a radiant indicator in a bottom section of the housing. The radiant indicator is translucent and acts as another indication that the sensor is over the hidden element. The sensor also includes a light source, such as an LED, which lights the radiant indicator with a beam, as well as optionally projecting an image on the surface, for example, formed by the bottom section and a top section of the housing. The same light source may also be used to project a second beam to an indicator on the top section of the housing.

Claims

1. A sensor configured to find a hidden element behind a surface, the sensor comprising:

a housing comprising a top section and a bottom section, wherein the bottom section comprises a radiant indicator in a front portion of the bottom section; and

circuitry coupled to the housing, wherein the circuitry comprises a light chamber having a light source and an opening, wherein the circuitry is configured to illuminate the radiant indicator by activating the light source;

wherein the light chamber is configured to reflect light to the opening in the light chamber to form a beam; and

wherein the radiant indicator is positioned to receive the beam.

2. The sensor of claim 1, further comprising a lens assembly coupled to the housing, wherein the lens assembly comprises a lens configured to optically connect the beam to the radiant indicator.

3. The sensor of claim 2, wherein the lens assembly is insertable into the bottom section.

4. The sensor of claim 1, wherein the top section and the bottom section form an opening in the housing configured to form an image against an adjacent surface.

5. The sensor of claim 1, further comprising a backing to the radiant indicator to provide a contrast to the radiant indicator.

6. The sensor of claim 1, further comprising a display positioned in the housing and coupled to the circuitry, wherein the light chamber further comprises a second opening positioned to project a second beam to the display.

7. The sensor of claim 6, wherein the display comprises a notched display.

8. The sensor of claim 6, wherein the display comprises an LCD display.

9. The sensor of claim 1, further comprising an opaque material, wherein the light chamber further comprises a second opening positioned to project a second beam to the opaque material.

10. The sensor of claim 9, wherein the second beam passes between the display and the opaque material.

11. The sensor of claim 1, wherein the radiant indicator is translucent and passive.

12. A method for finding a hidden element behind a surface using a sensor, the method comprising:

detecting the hidden element;

activating a light source to emit a light, based on detecting the hidden element;

reflecting the light in a light chamber;

forming a beam through an opening in the light chamber; and

illuminating a radiant indicator with the beam.

13. The method of claim 12, further comprising optically connecting the beam to the radiant indicator.

14. The method of claim 12, further comprising inserting a lens assembly into a front portion of a bottom section of a housing comprising a top section and the bottom section.

15. The method of claim 12, further comprising forming an opening in a housing, comprising a top section and a bottom section, configured to a form an image against an adjacent surface.

16. The method of claim 12, further comprising placing a backing to an under portion of the radiant indicator to provide a contrast to the radiant indicator.

17. The method of claim 12, further comprising:

forming a second beam through a second opening in the light chamber; and

illuminating a display with the second beam.

18. The method of claim 12, further comprising:

forming a second beam through a second opening in the light chamber; and

illuminating an opaque material with the second beam.

19. The method of claim 18, wherein part of the beam passes between a display and the opaque material.

20. A sensor configured to find a hidden element behind a surface, the sensor comprising:

means for detecting the hidden element;

means for activating a light source to emit a light, based on the means for detecting the hidden element;

means for reflecting the light;

means for forming a beam based on the means for reflecting the light; and

means for illuminating a radiant indicator with the beam.
