The device includes a self-leveling laser housing that allows the lasers to level when activated. The device also includes separate distance measuring lasers and a handheld display used to measure distances from the center of the device. ## Claims ### Claim 1 A laser leveling device that is configured to be removably attached to a work surface, the laser leveling device comprising: a laser assembly; a first leveling laser mounted to said laser assembly, said first leveling laser being configured to project a visible laser line onto the work surface when said first leveling laser is activated; a first distance measuring laser coupled to said laser assembly; a second leveling laser, said second leveling laser being arranged orthogonally to said first leveling laser; and a second distance measuring laser, wherein said first and second distance measuring lasers are oriented on respective first and second auxiliary axes, and wherein the first and second leveling lasers are oriented along respective first and second primary axes, said first and second auxiliary axes being parallel with respective first and second primary axes. ### Claim 2 (depends on 1) The laser leveling device of claim 1, further comprising a first base that is configured to be removably attached to the work surface relative to a reference point, said laser assembly being configured to selectively couple to said first base. ### Claim 3 (depends on 2) The laser leveling device of claim 2, wherein said first distance measuring laser is rotatable relative to said base such that said first distance measuring laser is rotatable relative to the reference point. ### Claim 4 (depends on 3) The laser leveling device of claim 3, wherein said first distance measuring laser is mounted to said first base such that coupling said laser assembly to said first base couples said first distance measuring laser to said laser assembly. ### Claim 5 (depends on 2) The laser leveling device of claim 2, wherein said first distance measuring laser is mounted to said first base such that coupling said laser assembly to said first base couples said first distance measuring laser to said laser assembly. ### Claim 6 (depends on 1) The laser leveling device of claim 1, wherein said laser assembly is configured to allow said first leveling laser to self-level such that the visible laser line is level. ### Claim 7 (depends on 1) The laser leveling device of claim 1, wherein said laser assembly comprises a means for adjusting pitch, roll, and yaw of said first leveling laser. ### Claim 8 (depends on 1) The laser leveling device of claim 1, further comprising a handheld device that wirelessly communicates with said first distance measuring laser and a means for wirelessly communicating with the handheld device, wherein the handheld device comprises a smartphone and an adjustable cradle for the smartphone that facilitates interruption of laser beam emitted from said first distance measuring laser, and wherein the smartphone comprises a software application for calculating and displaying distances when a laser beam emitted from said first distance measuring laser is interrupted. ### Claim 9 A positioning device comprising: a base that is configured to be removably attached to a work surface relative to a reference point; a first distance measuring laser mounted on the base; and a handheld device that wirelessly communicates with the first distance measuring laser, said handheld device being configured to interrupt a laser beam emitted from the first distance measuring laser. ### Claim 10 (depends on 9) The positioning device of claim 9, wherein said first distance measuring laser is rotatable relative to said base such that said first distance measuring laser is rotatable relative to the reference point. ### Claim 11 (depends on 9) The positioning device of claim 9, wherein the first distance measuring laser is connected to a means for wirelessly communicating with the handheld device. ### Claim 12 (depends on 9) The positioning device of claim 9, wherein the handheld device is a smartphone with a software application for calculating and displaying distances when a laser beam emitted from the first distance measuring laser is interrupted. ### Claim 13 (depends on 12) The positioning device of claim 12, wherein the handheld device comprises a smartphone and an adjustable cradle for the smartphone that facilitates interruption of laser beams emitted from the first distance measuring laser. ### Claim 14 (depends on 13) The positioning device of claim 13, wherein the smartphone comprises a software application for calculating and displaying distances when a laser beam emitted from the first distance measuring laser is interrupted. ### Claim 15 (depends on 9) The positioning device of claim 9, further comprising a laser assembly coupled to said base so as to form an integrated laser leveling device. ### Claim 16 A method for locating layout points on a work surface, the method comprising: removably attaching a base on the work surface relative to a first layout point; activating a first distance measuring laser mounted to the base, thereby causing the first distance measuring laser to emit a first laser beam; utilizing a handheld device to interrupt the first laser beam; positioning the handheld device relative to the first layout point; and positioning a second layout point relative to the handheld device, wherein the handheld wirelessly communicates with the first distance measuring laser. ### Claim 17 (depends on 16) The method of claim 16, wherein the handheld device comprises a smartphone and an adjustable cradle for the smartphone that facilitates interruption of the first laser beam. ### Claim 18 (depends on 17) The method of claim 17, wherein the smartphone comprises a software application for calculating and displaying distances when a laser beam emitted from the first distance measuring laser is interrupted.
