Abstract

A laser level receives information describing a series of install points. The laser level than projects one or more laser beams at the install point(s), such as a planar laser beam along the run and a targeting laser beam at the point selected by the user. After the user finishes work on a first install point, the user can instruct the laser level to project the targeting laser beam at the next point, such as the user sending the instruction wirelessly.

Claims (48)

1 . A laser generating assembly comprising:

a housing;

a first laser generation device coupled to the housing, the first laser generation device configured to generate a first output laser beam of light along a first plane, the first output laser beam of light intersecting an upper surface above the housing to form a first line on the upper surface that extends away from the housing;

a second laser generation device coupled to the housing, the second laser generation device configured to generate a targeting laser beam of light, the targeting laser beam of light projected at the upper surface at a first target intersecting the first line; and

a controller coupled to the housing, the controller configured to:

receive a first signal indicating that the targeting laser beam of light is intersecting a third surface at a first location, wherein the first target is a non-zero first lateral distance from the housing and wherein the first location is a non-zero second lateral distance from the housing that is less than the first lateral distance;

calculate a difference between the first lateral distance and the second lateral distance;

generate a second signal indicating the difference; and

transmit the second signal to a remote device configured to receive the second signal and provide an indication to a user that identifies the difference.

2 . The laser generating assembly of claim 1 , comprising:

a laser distance measurer coupled to the housing, the laser distance measurer configured to measure the second lateral distance and generate the first signal, which includes the second lateral distance.

3 . The laser generating assembly of claim 2 , wherein the controller is configured to receive a first information signal from the laser distance measurer, the first information signal indicating a vertical distance of the upper surface above the laser distance measurer.

4 . The laser generating assembly of claim 3 , wherein the laser distance measurer measuring the second lateral distance is based at least in part on the vertical distance.

5 . The laser generating assembly of claim 1 , the controller configured to:

receive a control signal to adjust the targeting laser beam of light; and

in response to receiving the control signal, adjusting the aim of the targeting laser beam of light a first adjustment distance from the first target such that the targeting laser beam of light intersects the first line at a location the first adjustment distance from the first target.

6 . The laser generating assembly of claim 5 , wherein the control signal instructs the second laser generation device to adjust the aim the targeting laser beam of light such that the targeting laser beam of light intersects the first line at a second target of a plurality of targets that is distinct from the first target, wherein the plurality of targets includes the first target.

7 . The laser generating assembly of claim 5 , wherein the control signal instructs the second laser generation device to adjust the aim of the targeting laser beam of light so that the targeting laser beam of light intersects the upper surface at an intersecting location that moves linearly along the first line at a constant speed with respect to the upper surface.

8 . The laser generating assembly of claim 5 , wherein the control signal instructs the second laser generation device to initially adjust the aim of the targeting laser beam of light so that the targeting laser beam of light intersects the upper surface at an intersecting location that moves linearly along the first line at a first speed with respect to the upper surface for a first length of time, and subsequent to the first length of time at a second speed with respect to the upper surface that is greater than the first speed.

9 . The laser generating assembly of claim 1 , wherein the remote device is configured to control the first laser generation device and the second laser generation device.

10 . The laser generating assembly of claim 1 , the controller configured to receive a third signal from the remote device that identifies a plurality of targets that includes the first target.

11 . The laser generating assembly of claim 1 , wherein the indication is selected from the group consisting of an audio alert, a visual warning message, and a haptic signal.

12 . The laser generating assembly of claim 1 , wherein the remote device is configured to control the second laser generation device.

13 . A laser generating assembly comprising:

a housing;

a first laser generation device coupled to the housing, the first laser generation device configured to generate a first output laser beam of light along a first plane, the first output laser beam of light intersecting an upper surface above the housing to form a first line on the upper surface that extends away from the housing;

receive a first signal to adjust the aim of the targeting laser beam of light so the targeting laser beam of light intersects the first line at a first alternate location;

calculate a non-zero lateral distance between the first alternate location and the first target;

generate a second signal indicating the lateral distance; and

transmit the second signal to a remote device configured to receive the second signal and display an indication to a user that identifies the lateral distance.

14 . The laser generating assembly of claim 13 , comprising:

a laser distance measurer coupled to the housing, the laser distance measurer configured to measure the lateral distance and generate the first signal, which includes the lateral distance, wherein the controller is configured to receive a first information signal from the laser distance measurer, the first information signal indicating a vertical distance of the upper surface above the laser distance measurer.

15 . The laser generating assembly of claim 14 , wherein the laser distance measurer measuring the lateral distance is based at least in part on the vertical distance.

16 . The laser generating assembly of claim 13 , wherein the first signal causes the second laser generation device to adjust the aim of the targeting laser beam of light so that the targeting laser beam of light intersects the upper surface at an intersecting location that moves linearly along the first line at a constant speed with respect to the upper surface.

17 . The laser generating assembly of claim 13 , wherein the first signal causes the second laser generation device to initially adjust the aim of the targeting laser beam of light so that the targeting laser beam of light intersects the upper surface at an intersecting location that moves linearly along the first line at a first speed with respect to the upper surface for a first length of time, and subsequent to the first length of time at a second speed with respect to the upper surface that is greater than the first speed.

18 . A laser generating assembly comprising:

a housing;

a first laser generation device coupled to the housing, the first laser generation device configured to generate a first output laser beam of light along a first plane, the first output laser beam of light intersecting an upper surface above the housing to form a first line on the upper surface that extends away from the housing;
