Detailed Description

Referring generally to the drawings, laser levels, such as dotted and planar laser levels, are provided. As will be generally understood, a laser level system including a laser transmitter and a remote control is used to align objects or features in an area (e.g., as along a hole of a wall, pipe, conduit, etc.).

In various embodiments, the laser levels described herein are configured to emit a laser beam toward a series of targets identified by a user. For example, when a user wants to install a series of support structures suspended from a ceiling, the laser level receives information identifying the location of a series of targets. The laser level then selectively projects a targeting laser beam at a target point selected by the user. The user can switch the targeting laser beam between the targets and fine tune the targeting laser beam between the targets. The various laser levels described herein provide this functionality while moving only a single laser beam (e.g., not including the laser beam used by the distance measurement device), thereby enabling the laser level to have a smaller form factor and/or housing than more comprehensive systems that provide other functionality. The various laser levels described herein have a firing platform that self-levels, such as by a pendulum, and all laser transmitters are supported on the self-leveling platform.

The various laser levels described herein detect obstructions that disrupt the targeted laser beam path. In response to detecting an obstacle, the laser level may signal the user about the obstacle, and the user may then adjust the target of the targeted laser beam to avoid the obstacle.

Referring to fig. 1-7, various aspects of a laser system 108 are shown that includes a laser generating assembly and/or laser beam generating device, shown as a laser level 110 and a remote control 210. Laser level 110 includes a housing 134, one or more laser generators, shown as laser diode(s) 158, configured to emit one or more laser beams (e.g., first output laser beam 116, laser beam light plane 124, vertical laser beam 120, and/or targeting laser beam 130) from laser level 110. The user controls the laser level 110 via the remote control 210, such as wirelessly controlling the laser level 110.

In various embodiments, laser level 110 includes a housing 112, a first laser generating device 113 coupled to housing 112, a second laser generating device 114 coupled to housing 112, and a controller 111 coupled to housing 112. In various embodiments, the laser generating device 113 is configured to generate a first output laser beam 116 along a first plane, the first output laser beam 116 intersecting an upper surface (e.g., ceiling 198) above the housing 112 to form a light ray 118 on the upper surface (e.g., ceiling 198) that extends away from the housing 112. In various embodiments, the laser generating device 114 is configured to generate a targeting laser beam 130, the targeting laser beam 130 being projected at a first target 170 at an upper surface (e.g., ceiling 198) that intersects the light ray 118.

Laser level 110 emits a first output laser beam 116 that is emitted forward from laser level 110, producing a light ray 118 on one or more surfaces (e.g., ceiling 198) from which light ray 118 extends above laser level 110. Laser level 110 also emits a vertical laser beam 120 vertically downward from housing 134, which creates a lower point 122 on one or more surfaces (e.g., a lower surface such as a floor below laser level 110). Laser level 110 emits a laser beam light plane 124, such as from housing 134 horizontally forward, that creates a horizontal line on one or more surfaces (e.g., the front and/or side walls of laser level 110).

In various embodiments, the laser level 110 includes a leveling system 156 that automatically levels the laser level 110 (e.g., by leveling the housing 134), such as by a vertical vial and/or an accelerometer. The laser level 110 includes one or more input buttons 144 that control the laser level 110 (e.g., receive input identifying a series of points to install, change modes of operation). In various embodiments, the laser diode(s) 158 include one or both of the first laser generating device 113 and the second laser generating device 114. For example, the laser level 110 includes a pendulum system that orients each of the laser diode(s) 158. In particular embodiments, one or more laser diodes 158 are supported on a platform that is self-leveling, such as by a pendulum (e.g., all laser diodes 158 on laser level 110 are supported on a self-leveling pendulum).

In particular embodiments, laser level 110 includes only laser diode(s) 158 that emit first output laser beam 116 and targeting laser beam 130. In particular embodiments, laser diode(s) 158 emit only first output laser beam 116, laser beam light plane 124, and targeting laser beam 130. In particular embodiments, laser diode(s) 158 emit only first output laser beam 116, laser beam light plane 124, vertical laser beam 120, and targeting laser beam 130. In particular embodiments, only one laser beam emitted by laser level 110 is moved relative to the body of laser level 110 (excluding the laser beam emitted by laser distance measurer 180).

The laser level 110 also emits a targeting laser beam 130 that identifies the target selected by the user for installation. As will be explained, the user may switch the point along the point travel (run) that the laser level 110 will identify. Laser level 110 also includes a distance measuring device (shown as laser distance measurer 180) that measures the distance along which laser beam 130 is projected.

In various embodiments, the controller 111 is configured to receive a first information signal (e.g., signal 204) from the laser distance measurer 180 that indicates a vertical distance (e.g., distance 196 in fig. 20) of the upper surface (e.g., ceiling 198) above the laser distance measurer 180. In various embodiments, the laser distance measurer 180 measures the lateral distance 209 based at least in part on the vertical distance 196 (e.g., by knowing the vertical distance 196 and the distance of the hypotenuse (i.e., the targeted laser beam 130), the controller 111 can calculate the horizontal distance). After calculating the horizontal distance projected by the targeting laser beam 130, the laser level 110 may determine whether an obstacle is present, such as if the projected horizontal distance of the targeting laser beam 130 is less than expected, the laser level 110 may determine that an obstacle surface is present on which the targeting laser beam 130 is projected.

In other words, laser distance measurer 180 is configured to measure a distance from laser level 110 to an upper surface of one or more surfaces above laser level 110. The controller 111 is configured to receive a first information signal from the laser distance measurer 180 indicating a distance to an upper surface above the laser level 110, wherein the light 118 is generated at least partially on the upper surface.

Referring to fig. 8, a schematic diagram of laser level 110 is provided. The laser level comprises a laser distance measurer 180, a controller 111 and laser generating means 113, 114. A signal 202 is generated and transmitted between the laser distance measurer 180 and the controller 111 (e.g., from the laser distance measurer 180 to the controller 111, and/or from the controller 111 to the laser distance measurer 180). A signal 204 is generated and transmitted between the controller 111 and the laser generating devices 113, 114 (e.g., from the controller 111 to the laser generating devices 113, 114, and/or from the laser generating devices 113, 114 to the controller 111). A signal 206 is generated and communicated between laser level 110 and remote control 210 (e.g., from laser level 110 to remote control 210, and/or from remote control 210 to laser level 110).

In various embodiments, the controller 111 is configured to receive a first signal (e.g., signal 202) indicating that the targeting laser beam (e.g., targeting laser beam 130) intersects a third surface (e.g., a blocking surface other than the ceiling 198 (e.g., see fig. 25)) at a first location (e.g., projected target 171). In various embodiments, a laser distance measurer 180 is coupled to the housing 112, and the laser distance measurer 180 is configured to measure a lateral distance 209 of the targeted laser beam 130 intersecting a surface (e.g., a third surface 169 different from the surface of the ceiling 198 shown in fig. 26) and generate a first signal (e.g., signal 202 in fig. 8) including the second lateral distance 209.

In some cases, a first target (e.g., target 170) is a non-zero first lateral distance 208 (fig. 26) from the housing 112, and the projected target 171 is a non-zero second lateral distance 209 (fig. 26) from the housing 112 that is less than the first lateral distance 208. In various embodiments, the controller 111 is configured to calculate a difference between the first lateral distance 208 and the second lateral distance 209, generate a second signal (e.g., signal 206) indicative of the difference, and transmit the second signal to a remote device (e.g., remote control 210) configured to receive the second signal and provide an indication to the user identifying the difference. In various embodiments, the indication provided by remote control 210 to the user is selected from the group consisting of an audio alert, a visual warning message, and a haptic signal.

In various embodiments, the controller 111 receives a signal to adjust the targeting laser beam 130 slightly away from the target. For example, the controller 111 is configured to receive a control signal (e.g., signal 206 from the remote control 210) to adjust the targeting laser beam, and in response to receiving the control signal, adjust the target of the targeting laser beam (e.g., the targeting laser beam 130) a first adjustment distance (e.g., adjustment distance 176 in fig. 4) from the first target (e.g., target 171) such that the targeting laser beam 130 intersects the light ray 118 at a location that is a first adjustment distance 176 from the first target 171.

In various embodiments, the controller 111 receives signals to target different targets. For example, the controller 111 receives a control signal (e.g., signal 206 from the remote control 210) that instructs the second laser generating device 114 to adjust the target of the targeting laser beam 130 such that the targeting laser beam 130 intersects the light ray 118 at a second target (e.g., target 363 in fig. 3) of the plurality of targets (e.g., the plurality of targets 360 in fig. 3) that is different from the first target (e.g., target 361), and the plurality of targets 360 includes the first target 361.

The targeting laser beam 130 forms a target image 131 on the surface, the target image 131 intersecting the light ray 118 at the selected target. As will be explained, the laser level 110 is configured to emit one or more types of target images 131, such as target lines, target spots, target X, and/or target circles and spots (see fig. 16-19).

Laser level 110 includes a controller 111 that controls various aspects of laser level 110. In various embodiments, the controller 111 is configured to receive information identifying a plurality of targets (e.g., the plurality of targets 360), receive a first control signal to emit the targeting laser beam 130 toward a first target (e.g., the first target 361, referred to as the actual target 170 in some use cases described herein) of the plurality of targets 360, and, in response to receiving the first control signal, adjust the targeting laser beam 130 such that the target image 131 is projected to intersect the light ray 118 at the first target. In various embodiments, the controller 111 of the laser level 110 receives a signal (e.g., signal 206) from the remote device 210 identifying a plurality of targets 360 including the first target 361.

In various embodiments, the laser level 110 includes a window 159 through which the targeting laser beam 130 is projected, and the window 159 is curved and centered about the targeting laser beam 130 such that refraction through the window is constant when the targeting laser beam 130 is adjusted. Alternatively, the window 159 is not centered on the targeting laser beam 130 (e.g., the window 159 is flat), and the system accounts for deflection of the targeting laser beam 130 through different portions of the window 159 when adjusting the targeting laser beam 130. In various embodiments, laser level 110 includes wireless communication, such as infrared, within laser level 110 (e.g., between the housing and the pendulum) to reduce internal wiring.

For example and referring to fig. 3, a user plans to install a series of points along multiple targets 360. The plurality of targets 360 includes a first target 361, a second target 363, a third target 364, a fourth target 365, and a fifth target 366. The first target 361 and the second target 363 are separated by a gap 362. In each case, each point on the plurality of targets 360 is separated from their neighbors by a space 362. Alternatively, and as will be explained, the dot strokes may be separated by different spacing arrangements (e.g., alternating series of first intervals and subsequent series of second intervals, etc.). As the targeting laser beam 130 is adjusted (e.g., in direction 207), the angle 136 of the targeting laser beam 130 changes relative to vertical. As will be described, in various embodiments, the laser level 110 sometimes uses the angle 136 to make a determination as to the target of the targeted laser beam 130.

Referring to fig. 4, the laser level 110 is configured to emit a targeted laser beam 130 a distance 132, such as at least 50 feet. Referring to fig. 5, in various embodiments, the laser level 110 includes a fine adjuster 138 for performing small adjustments to the laser level 110 and/or an auto-aligner 142 for auto-aligning one or more laser beams emitted from the laser level 110. Referring to fig. 6, in various embodiments, laser level 110 includes a motorized base 140 to move and/or redirect laser level 110, such as motorized base 140 that may be controlled by remote control 210.

Referring to fig. 7, a laser level 143 is shown according to an exemplary embodiment. The laser level 143 is substantially identical to the laser level 110 except for the differences discussed herein. The laser level 143 includes an input button 145 for receiving input such as information indicating details of a series of points to be installed, and a screen 146 for providing feedback to the user such as feedback regarding the information the user is providing. In various embodiments, laser level 110 also includes a screen similar to screen 146.

Referring to fig. 9-10, various aspects of a remote control 210 are shown. Remote control 210 is configured to control (e.g., wirelessly control) a laser level, such as laser level 110, within laser system 108. In various embodiments, the remote controller 210 is configured to control the first laser generating device 113 and the second laser generating device 114. In various embodiments, the remote control 210 is configured to control the second laser generating device 114. Remote control 210 includes a housing 212 and a screen 214 coupled to housing 212.

Referring to fig. 9, various aspects of screen 214 are shown when a user configures a trip (e.g., multiple targets 360). In various embodiments, screen 214 displays an option for selecting interval mode 216. As a first example ("AAAA"), the selected interval pattern 216 is that each interval is the same distance. As a second example ("ABAB"), the selected spacing pattern 216 is that the spacing distance alternates between two distances, so that the odd spacing (i.e., 1 st, 3 rd, 5 th, etc.) is a first distance a and the even spacing (i.e., 2 nd, 4 th, 6 th, etc.) is a second distance B that is different from distance a. As a third example ("ABCD"), the selected interval pattern 216 is unique for each interval relative to the other intervals. Screen 214 also displays: a selected separation distance 218, in this case four feet; a stroke length 220 representing the total length of the stroke, which in this case is 40 feet; and/or points 222, which in this case are 10 points.

In various embodiments, laser level 110 is configured to receive any two of separation distance 218, travel length 220, and points 222, and laser level 110 calculates and displays the remaining data. For example, the user inputs the interval length and the total run length, and the laser level 110 calculates the total points.

Referring to fig. 10, various aspects of screen 214 are shown as a user installing points along a trip. For example, in various embodiments, the screen 214 displays the separation distance 226, the point number 224 being installed (e.g., the 1 st point along the journey), the target distance 228 of the point number 224, and the current distance 230 at which the target image 131 is projected by the targeting laser beam 130. As will be explained, the target distance 228 and the current distance 230 may be different numbers when the targeting laser beam impinges an obstacle or adjusts in response to an obstacle.

Remote control 210 includes buttons 232 that adjust the point along the travel that is currently targeted. The remote control 210 also includes a button 234 that performs fine adjustments to the targeted laser beam 130, such as in response to an obstruction. The button 234 performing fine adjustments is configured to adjust the target of the targeted laser beam 130 to move slowly (e.g., one inch per second).

In various embodiments, the laser level 110 is configured to move the targeting laser beam 130 such that the targeting laser beam 130 moves on the ceiling at a constant speed. For example, when the targeting laser beam 130 is aimed a far horizontal distance (e.g., 50 feet), a very small adjustment of the angle 136 of the targeting laser beam 130 will result in a much larger movement of the targeting line 148 than when the targeting laser beam 130 is aimed closer to the laser level 110. Thus, the user does not have to consider these geometric issues in adjusting the targeting laser beam 130, and the laser level 110 calculates the speed at which the angle 136 is changed so that the target image 131 produced by the targeting laser beam 130 (e.g., the targeting line 148) moves on the ceiling at a constant speed regardless of the size of the angle 136 (i.e., regardless of the horizontal distance between the targeting line 148 and the laser level 110).

For example, the laser level 110 (e.g., the controller 111) receives a control signal that instructs the second laser generating device 114 to adjust the target of the targeting laser beam 130 such that the targeting laser beam 130 intersects the upper surface (e.g., the ceiling 198) at an intersection location that moves linearly along the ray 118 at a constant speed relative to the upper surface (e.g., the ceiling 198).

As another example, the laser level 110 may initially adjust the targeted laser beam 130 at a first speed and then adjust at a faster second speed, thereby helping to make faster adjustments. In particular, the laser level 110 (e.g., the controller 111) may receive a control signal that instructs the second laser generating device 114 to initially adjust the target of the targeting laser beam 130 such that the targeting laser beam 130 intersects the upper surface (e.g., the ceiling 198) at an intersection location that moves linearly along the first light ray 118 at a first speed relative to the upper surface for a first time length (e.g., 2 seconds) and after the first time length moves at a second speed relative to the upper surface that is greater than the first speed.

Remote control 210 also includes a set button 236. As will be explained, after fine adjustments have been performed on the selected target, the set button 236 reconfigures the distance to a subsequent point along the travel in response to any fine adjustments having been made.

In various embodiments, the controller 111 is configured to receive the second control signal to adjust the targeting laser beam 130 according to the first target 361, and in response to receiving the second control signal, adjust the targeting laser beam 130 by a first adjustment distance (e.g., a first adjustment distance 176 in fig. 42) such that the target image 131 intersects the light ray 118 at a first adjustment distance from the first target 361. In various embodiments, the second control signal instructs the laser level 110 to move the targeting laser beam 130 such that the target image 131 intersects the first light ray 118 at a second target 363 of the plurality of targets 360 that is different from the first target 361.

In various embodiments, the second control signal instructs the laser level 110 to move the target image 131 linearly along the first light ray 118 at a constant speed (e.g., one inch per second). In various embodiments, the second control signal instructs the laser level 110 to initially move the target image 131 linearly along the first light ray 118 at a first speed (e.g., one inch per second) for a threshold period of time (e.g., three seconds), and to move the target image at a second speed (e.g., 1.5 inches per second) that is greater than the first speed after the threshold period of time.

In various embodiments, the controller 111 is configured to receive a third control signal (e.g., the user presses the set button 236) to reset each of the plurality of targets 360 in the target sequence following the selected target (e.g., the first target 361), and in response to receiving a signal such as the third control signal, the controller 111 is further configured to adjust each of the plurality of targets following the selected target (e.g., the first target 361) by a first adjustment distance (e.g., the first adjustment distance 176).

In one exemplary use, the user works on a trip that includes points at 0', 10', 20', and 30'. The user installs at 0 'and then when installing at 10', the user finds that the pipe blocks the way. The user then fine-tunes the laser, e.g., shortens the target by two inches, so that the laser is now pointed at 9'10". After installing the point at 9'10", one option for the user is to continue the installation at a predetermined point (e.g., at 20' and 30 '). Another option for the user is to press the set button 236 and adjust the subsequent point in response to fine adjustments performed by the user. In particular, subsequent mounting points will become 19'10 "and 29'10" after the set button 236 is pressed (e.g., all subsequent points are now adjusted in a similar direction and distance as the user adjusted the first point in response to the obstacle).

Referring to fig. 11 through 14, a remote controller 260 according to an exemplary embodiment is shown. Remote control 260 is substantially identical to remote control 210 except for the differences discussed herein. Remote control 260 includes a housing 262, a screen 264, an interface 266 displaying options for user selection, and buttons 268 for user selection and instruction.

In various embodiments, remote control 210, remote control 260, and/or remote control 280 are configured to fall from above (e.g., at most 10', or more specifically at most 16', or even more specifically at most 38 '), and to withstand no or minimal permanent damage. Thus, the remote control may be used by an overhead worker on an elevator (e.g., a scissor lift).

Referring to fig. 15, a remote control 280 according to an exemplary embodiment is shown. Remote control 280 is substantially identical to remote control 210 or remote control 260, except for the differences discussed herein. In particular, remote control 280 is smaller than remote control 260 and remote control 210. Remote control 280 includes a housing 282, a screen 284, and buttons 286 for a user to select and give instructions. In various embodiments, when the user clicks on button 286 (e.g., quick press and release), laser level 110 moves to the next or previous target in the trip, depending on whether the left or right button is pressed. Alternatively, if the user holds button 286, fine adjustment is initiated and laser level 110 moves the resulting target produced by targeting laser beam 130 (e.g., targeting line 148) on the ceiling at a slow rate (e.g., one inch per second). In various embodiments, as the user continues to hold button 286, the speed of targeting line 148 slowly increases (e.g., one inch per second from the first three seconds increases to 1.5 inches per second for the next second, to 2 inches per second for the next second).

Referring to fig. 16-19, laser level 110 is configured to emit one or more types of targeting laser beams 130 to produce a targeting indication along light ray 118. Referring to fig. 16, the targeting laser beam 130 produces a targeting spot 150 at a selected mounting point. Referring to fig. 17, the targeting laser beam 130 produces a targeting line 148 at the selected mounting point. Referring to fig. 18, the targeting laser beam 130 produces a targeting X152 at a selected mounting point. Referring to fig. 19, the targeting laser beam 130 produces a targeting circle and spot 154 at the selected mounting point.

Referring to fig. 20, in various embodiments, when the targeting laser beam 130 projects a distance 160 (e.g., 50 feet), the targeting laser beam 130 has an accuracy 162 that creates a target within 1 "of the target and has a width 164 of 1". More specifically, the precision 162 of the targeting laser beam 130 is 0.5", and even more specifically 0.25", and the width 164 of the targeting laser beam 130 at 50' is 0.5". As shown, the laser level 110 is a distance 196 from the ceiling.

Referring to fig. 21-25, in various cases, the targeting laser beam 130 is blocked by an obstacle, and thus, the targeting line 148 generated by the targeting laser beam 130 intersects the actual target 170. Instead, the targeting laser beam 130 projects an image at the projected target 171 that is a non-zero distance from the actual target 170. Referring to fig. 22, when laser level 110 detects this, laser level 110 may transmit a distance 166 from a previous target 178 to a location where the targeted laser beam 130 intersects an obstacle at projected target 171. Referring to fig. 23, when laser level 110 detects this, laser level 110 may transmit a distance 168 from the actual target 170 to a location where the targeted laser beam 130 intersects an obstacle at the projected target 171.

Referring to fig. 24, in various embodiments, in response to the remote control 210 detecting an obstacle, the remote control 210 displays an indication 238 (e.g., a warning message) on the screen, the remote control 210 generates an audio warning (e.g., an audible beep), and/or the remote control 210 blinks one or more laser beams (e.g., the targeting laser beam 130). Referring to fig. 25, remote control 260 displays a warning message on a screen, remote control 260 generates an audio warning (e.g., an audible beep), and/or remote control 260 blinks one or more laser beams (e.g., targeting laser beam 130).

Referring to fig. 26-30, an exemplary method of installing at a target point even if there is an obstacle is provided. Referring to fig. 26, the targeting laser beam 130 is blocked by an obstacle, thereby preventing the targeting laser beam 130 from intersecting the actual target 170. Referring to fig. 27-28, the user measures the distance 168 from the intersection of the targeting laser beam 130 and the obstacle at the projected target 171 to the actual target 170. Referring to fig. 29-30, the user then performs the installation at the actual target 170 and proceeds to the next installation target (if any).

Referring to fig. 31-35, an exemplary method of installing at a target point even if there is an obstacle is provided. Referring to fig. 31, the targeting laser beam 130 is blocked by an obstacle, thereby preventing the targeting laser beam 130 from intersecting the real target 170. Referring to fig. 32, the user performs fine adjustments to the targeting laser beam 130 until the targeting laser beam 130 is no longer blocked and is directed to the updated target 172. Then, the user refers to the remote controller (e.g., remote controller 210) to determine the adjustment amount (e.g., see current distance 230 in fig. 10), and measures backward (fig. 33). Referring to fig. 34-35, the user then performs the installation at the actual target 170 and proceeds to the next installation target (if any).

In other words, the controller 111 of the laser level 110 is configured to receive the first signal to adjust the target of the targeting laser beam 130 such that the targeting laser beam 130 intersects the light ray 118 at a first alternate location (shown as an updated target 172), calculate a non-zero lateral distance 176 between the first alternate locations (e.g., the updated target 172) and the first target 170, generate a second signal (e.g., signal 206 in fig. 9) indicative of the lateral distance 176, and transmit the second signal 206 to a remote device (e.g., remote device 210) configured to receive the second signal 206 and display an indication identifying the lateral distance to a user (e.g., see fig. 10). Alternatively, both distance 208 and distance 209 (see FIG. 25) are transmitted from laser level 110 to remote control 210.

With reference to fig. 36-39, an exemplary method of installing at a target point even if there is an obstacle is provided. Referring to fig. 36, the targeting laser beam 130 is blocked by an obstacle, thereby preventing the targeting laser beam 130 from intersecting the real target 170. Referring to fig. 37, the user adjusts the laser level 110 to point to the next target 174 and measures the separation distance from the next target 174 to the actual target 170. Referring to fig. 38-39, the user then performs the installation at the actual target 170 and proceeds to the next installation target (if any).

Referring to fig. 40-43, an exemplary method of installing at a target point even if there is an obstacle is provided. Referring to fig. 40, the targeting laser beam 130 is blocked by an obstacle, thereby preventing the targeting laser beam 130 from intersecting the real target 170. Referring to fig. 41, the user adjusts the targeting laser beam 130 to point to the updated target 172. Referring to fig. 42 to 43, the user then performs installation at the updated target 172 and proceeds to the next target 174.

Alternatively, in various embodiments, a user selects a button (e.g., set button 236, see fig. 9-10 and accompanying description) to adjust each subsequent target of the plurality of targets 360 according to the adjustment from the actual target 170 to the updated target 172. For example, if the updated target 172 is moved a distance X (e.g., approximately 5 "from the laser level 110) relative to the actual target 170, each subsequent point in the plurality of targets 360 (e.g., each target farther from the laser level 110 than the actual target 170) is adjusted by the same distance X (e.g., in this example, each subsequent point in the plurality of targets 360 is moved approximately 5" from the laser level 110).

Referring to fig. 44-50, various methods of carrying and/or securing a remote control by a user are shown. By way of example, remote control 260 may be coupled to a user's belt (fig. 44), remote control 280 may be coupled to a user's belt (fig. 45), remote control 280 may be coupled to a strap (fig. 46) that surrounds the user (e.g., around the user's neck), remote control 280 may be coupled to a user's helmet (fig. 47), remote control 260 may be coupled to a strap (fig. 48) that is coupled to the user (e.g., around the user's arm), remote control 260 may be coupled to a platform, such as a movable platform (fig. 49), and/or remote control 260 may be coupled to a ladder (fig. 50).

Referring to FIG. 51, an exemplary method 310 of using a laser system 108 (e.g., laser system 108 including laser level 110) is provided. Beginning at step 312, laser level 110 is activated. In various embodiments, the laser level 110 initiates the leveling and homing process. For example, one or more axles are leveled by using a gravity pendulum and one or more axles are leveled by a motor.

At step 314, the user aims the laser level 110. For example, laser level 110 is placed in a position such that laser level 110 is below (or above) a selected location, such as a starting point in a room. In various embodiments, the user adjusts the fine adjuster 138 to make fine adjustments to the position and/or target of the laser level 110. Laser level 110 is also aligned with strokes such as multiple targets 360. For example, the user uses the auto-aligner 142 and/or the motorized base 140 to orient and/or aim the laser level 110 along the plurality of targets 360.

At step 316, laser level 110 measures the distance to the upper surface (e.g., ceiling 198). For example, the laser distance measurer 180 measures the distance to the ceiling 198. In various embodiments, the distance to the ceiling is measured after leveling of the laser level 110 is completed and in response to the leveling. In various embodiments, the laser level 110 stores a minimum height for preventing blocking operations, and the laser level 110 further includes an option for the user to ignore the minimum height.

At step 318, details of the travel, such as the multiple targets 360, are entered, such as via input buttons on the remote control 210 or laser level 110. In various embodiments, the user enters details of the first trip into a remote control, such as remote control 210. Referring to fig. 9 and associated paragraph(s), the user selects a selected interval pattern 216 (e.g., AAAA, AAAABBBB, ABAB, ABCABCABC, ABCD). The spacing pattern 216 of "AAAA" uses the same spacing between each targeting point on multiple targets 360. The interval option AAABBBB uses a first interval distance for the first three intervals and then uses a second interval distance different from the first distance for the next three or more intervals. Interval options ABABAB and abccabc use the repetition interval option. In particular, ABABAB alternates between two separation distances, and abcapcabc alternates between three separation distances. The interval option ABCD uses a different interval distance for each interval, or at least a different interval distance for each of the first three intervals. In various embodiments, the remote control stores and displays previous separation distances that have been used by the user for easier selection.

At step 320, the user selects a mounting point. For example, the user selects the first target 361 on the plurality of targets 360.

At step 322, laser level 110 determines whether any errors are detected. If an error is detected, laser level 110 may activate an alarm, such as an audio alarm, a flashing light, a flashing laser, a warning message on the remote control (e.g., text on the screen indicating "blocked", such as flashing text), a vibration/tactile signal on remote control 210, such as based on the measurement of laser distance measurer 180, displaying the outline of the obstacle in remote control 210.

As a first example, if the time that laser level 110 targets the selected target exceeds a predetermined time limit, then the obstacle is marked and one or more warnings are initiated.

As a second example, if the distance projected by the targeting laser beam 130 skips the targeting distance, then the obstruction is marked. For example, if the expected distance to the target is 15 feet, and the projected distance of the targeting laser beam 130 hops between 14 feet and 16 feet as the targeting laser beam 130 moves back and forth (e.g., closer to and farther from the laser level 110), then the obstacle is marked. In various embodiments, laser level 110 includes a threshold distance for jumping distances to avoid marking false obstructions.

As another example, if the targeting laser beam 130 splits between two objects, the marking is wrong. In this case, the laser distance measurer 180 measures the distance to each object to determine whether the difference is above a threshold. In various embodiments, different distance measurements are averaged, using a minimum distance, or using a maximum distance.

For example, the laser level 110 determines whether the targeting laser beam 130 is aimed at a desired distance from the laser level. For illustrative and exemplary purposes only, if the ceiling height is 9 feet and the target point is 12 feet below the trip, the expected distance from the laser level 110 to the target point is 15 feet (3-4-5 triangles with the targeting laser beam 130 projected on the hypotenuse). If the laser level 110 detects that the targeted laser beam 130 is projected at a point 13.5' from the laser level 110, the laser level 110 may activate one or more warning signals (e.g., an audio alert, a flashing light, a flashing laser beam, a warning on a remote control).

In various embodiments, when the laser level 110 detects an obstacle, the laser level 110 makes adjustments similar to user actions performed at the previous obstacle. For example, if the user previously moved the targeting laser beam 130 to the next target so that the user could measure backward from the subsequent target, the laser level 110 could immediately target the subsequent target so that the user could measure backward again from the subsequent target.

As another example, the laser level 110 may detect the presence of two surfaces that each have the same expected distance for the targeting laser beam 130 to target the actual target 170. In various embodiments, the laser level 110 selects the first target, the last target, and/or stops at one target, and allows the user to make adjustments as desired.

As another example, the laser level 110 may rotate the targeting laser beam 130 to a desired angle and if the measured distance is incorrect, the laser level 110 may mark an error.

As another example, the laser level 110 may detect the ceiling using a series of points along substantially the same slope. Anything that is not considered a ceiling is marked as an obstacle.

In various embodiments, using the laser system 108 and/or the laser level 110 includes detecting an obstacle intersecting the targeting laser beam 130, and thus the targeting laser beam 130 forms a target image 131 at a location outside of the selected target (e.g., the first target 361). The method further includes generating an alarm in response to detecting the obstacle and/or generating an alarm signal to a remote control controlling the laser beam generating device.

In various embodiments, one or more remote controls (e.g., remote control 210) described herein are configured to receive an alert signal that laser level 110 detected an obstacle and generate an alert in response to receiving the alert signal. In various embodiments, the alert generated by the remote control (e.g., remote control 210) is selected from the group consisting of an audio alert, an on-screen warning message for a remote control, and a haptic signal.

At step 324, the user performs an adjustment, such as a fine adjustment, to bypass the obstacle. As one example, the user may adjust the targeting laser beam 130 to target just behind the obstacle, and then measure backward from the location at which the targeting laser beam 130 is aimed (e.g., see fig. 31-35). As another example, the user may adjust the targeting laser beam 130 to not intersect an obstacle and use the new point as a new installation location (see, e.g., fig. 40-43). In this second example, the user may optionally click on the setup button 236 to reconfigure each subsequent point along the plurality of targets 360 according to the adjustment just made (e.g., if the target point moves 2 inches back, clicking on the setup button 236 will move each subsequent target point 2 inches back).

As another example, the user may move an obstacle (e.g., an elevator on which the user rides) and instruct the laser level 110 to re-target the targeting laser beam 130 to the selected target.

As another example, the laser distance measurer 180 may be targeted downward to intersect another object below an obstacle onto a length and/or thin building material. The user then slides the remote control to intersect the targeted laser beam 130 and the measurement will be adjusted on the screen.

As another example, a tape measure is built into the remote control 210 so that the user can have one less object to carry.

As another example, the screen of the remote control 210 may show readings from the laser level 110 and/or leveling vials and/or digital vials on the remote control 210.

As another example, the remote control 210 may include a string potentiometer, so the user does not have to pull a tape measure to make the measurement.

As another example, the laser level 110 adjusts the targeting laser beam 130 to be horizontal. The user then interrupts the targeted laser beam 130 with the remote control 210 and when the correct distance is reached, the user is notified. The user then projects a laser beam upward from that point (e.g., using another laser level projecting a vertical line upward).

At step 326, the user then installs the object at the target (e.g., as the actual target 170 on multiple targets 360) and/or marks the point for later installation.

The user then selects the next installation point at step 328. If there are more points, the method loops back to step 322, otherwise an alert is generated to the user indicating that all points along the trip have been installed and/or marked (e.g., the user is at the end of the trip).

In various embodiments, the remote control 210 includes input options (e.g., buttons) that the user presses to help the user find the targeting laser beam 130, such as swinging the targeting laser beam 130, blinking the targeting laser beam 130, and/or fine-tuning the targeting laser beam 130.

In various embodiments, laser level 110 scans the entire trip (e.g., all targets on multiple targets 360) to detect obstacles and/or problems. The user may then adjust for the problems before they occur, thereby making the installation of the entire journey simpler and/or the points more consistent with each other. For example, laser level 110 identifies an obstacle, then presents an alternate instruction layout to the user that avoids the obstacle, which may or may not be installed.

In various embodiments, laser level 110 may display all points simultaneously, such as a rotating laser that selectively turns the laser beam off/on by a galvanometer or by its sides. In various embodiments, the magnetic shavings (MAGNETIC SHAVINGS) may be on a door on the L-shaped bracket. In various embodiments, the speed of fine adjustment varies based on the time the user presses the button (e.g., fine adjustment speeds up). In various embodiments, a kick-proof strobe light is present on the laser level housing. In various embodiments, remote control 210 may interface to a device within laser system 108 (e.g., laser level 110). In various embodiments, laser level 110 includes a "find me" button that triggers an alarm from remote control 210 when remote control 210 is lost. In various embodiments, the ceiling height may be entered via the remote control 210.

In various embodiments, the mirror is remotely controlled to automatically align with the laser beam and bypass shadows. In various embodiments, there are applications for controlling laser level 110. In various embodiments, laser level 110 may be placed in the middle of a stroke and projected in both directions. In various embodiments, laser level 110 is projected from above onto the ground. In various embodiments, the laser level 110 may be ceiling mounted and horizontally emitted for interception by a remote control.

Referring to fig. 52-53, various aspects of laser level 110 are shown. In particular, an emission platform 179 of laser level 110 is shown. In various embodiments, launch platform 179 is supported on a platform that is self-leveling, such as by a pendulum, such that launch platform 179 is configured to maintain a consistent orientation with respect to gravity. For example, the laser beam emitted by the laser diode 184 is made horizontal (level) with respect to gravity (e.g., vertical, horizontal).

The launch platform 179 includes a first platform 182 and one or more laser-generating diodes 184 that project the laser beam 120 (e.g., a downwardly aimed vertical beam), a first output laser beam 116 (e.g., a vertical beam extending along a target line), and a laser beam light plane 124 (e.g., a forwardly projected horizontal beam). In particular, the laser beam does not pivot when the second stage 188 rotates relative to the first stage. Launching platform 179 includes a second platform 188 that is pivotally coupled to first platform 182 such that second platform 188 rotates about axis 192 relative to first platform 182. In particular, the teeth of the worm gear 186 engage with the teeth of the circular gear 190, and the worm gear 186 rotates to rotate the second platform 188 relative to the first platform 182. As the second stage 188 rotates, one or more laser generating diodes 194 of the projection target laser beam 130 rotate.

In various embodiments, laser distance measurer 180 is coupled to second platform 188 such that laser distance measurer 180 also rotates relative to first platform 182 and/or the housing of laser level 110. In various embodiments, the laser distance measurer 180 uses a monocular system (e.g., one lens for transmitting and receiving laser beam light). In various embodiments, the laser distance measurer 180 uses a binocular system (e.g., two lenses for transmitting and receiving light).

In various embodiments, laser level 110 projects a cross line using a plurality of lenses, and laser level 110 includes a pendulum, a housing (e.g., launch platform 179) on the pendulum. One or more components, such as the second platform 188, are controlled by a motor. Laser level 110 also includes custom optics.
