LEVEL
First Claim
1. A level, comprising:
- a frame including a top planar surface, a bottom planar surface, and a web coupling the top planar surface to the bottom planar surface, the top planar surface and the bottom planar surface being parallel;
a vial supported by the frame, the vial having a longitudinal axis passing through a center of the vial and a body defining an interior containing a liquid and an indicator bubble; and
a plurality of LEDs, each of the LEDs has a light emitting point, and each of the plurality of LEDs is positioned adjacent an end of the vial and is oriented such that the light emitting point is positioned within the interior of the body of the vial.

Abstract
A level includes a frame having a top planar surface, a bottom planar surface, and a web coupling the top planar surface to the bottom planar surface. The top planar surface and the bottom planar surface are parallel. The level further includes a vial supported by the frame. The vial has a longitudinal axis passing through a center of the vial and a body defining an interior containing a liquid and an indicator bubble. The level further includes a plurality of LEDs. Each of the LEDs has a light emitting point, and each of the plurality of LEDs is positioned adjacent an end of the vial and is oriented such that the light emitting point is positioned within the interior of the body of the vial.

9. A level, comprising:
-
a frame including a top planar surface, a bottom planar surface, and a web coupling the top planar surface to the bottom planar surface, the top planar surface and the bottom planar surface being parallel; a plurality of vials each supported by the frame including a first vial having a first longitudinal axis that is oriented at a first vial orientation, and a second vial having a second longitudinal axis that is oriented at a second vial orientation not parallel with the first vial orientation; a first light source associated with the first vial; a second light source associated with the second vial; and an orientation sensor configured to turn on the first light source when the level is oriented in a first level orientation corresponding to the first vial orientation to illuminate the first vial, the orientation sensor configured to turn on the second light source when the level is oriented in a second level orientation corresponding to the second vial orientation to illuminate the second vial. - View Dependent Claims (10, 11, 12, 13, 14, 15)
