| 摘要 | A level for indicating the orientation of a surface includes a first planar surface, a second planar surface, a web coupled to the first planar surface and the second planar surface such that the first planar surface is spaced apart from and is parallel to the second planar surface, and a vial having a long axis and containing a liquid and a gas bubble. The level also includes a first magnet coupled to the first planar surface, a second magnet coupled to the first planar surface and spaced apart from the first magnet by a first distance, and a third magnet coupled to the first planar surface and spaced apart from the second magnet by a second distance that is different than the first distance. The first, second, and third magnets are positioned along the first planar surface successively without any additional magnets positioned therebetween. | ||

| 主权项 | 1. A level for indicating the orientation of a surface, the level comprising: a first planar surface; a second planar surface; a web coupled to the first planar surface and the second planar surface such that the first planar surface is spaced apart from and is parallel to the second planar surface; a vial having a long axis and containing a liquid and a gas bubble, the vial coupled to the web; a first magnet coupled to the first planar surface; a second magnet coupled to the first planar surface and spaced apart from the first magnet by a first distance; and a third magnet coupled to the first planar surface and spaced apart from the second magnet by a second distance that is different than the first distance; wherein the first, second, and third magnets are positioned along the first planar surface successively without any additional magnets positioned therebetween. | ||
