Abstract:
A laser distance and angle calculator that will give three measured distances simultaneously; for example from Point A to B, Point A to C and Point B to C. It will also calculate the angle at each intersecting points. The angle at your point of reference is required, but the other angles are calculated. 
     The laser control is used to rotate the corresponding laser. As each laser is pointed to their respective targets, the distances to these are captured. The lasers are optionally placed adjacent to each other or one above the other. The angle between these two points are also captured. With these pieces of captured data, the distance between the two targets along with the angles formed by this triangular formation will be calculated. This data will then be displayed on the LCD. This data can be cleared and the process repeated as often as desired.

RELATED APPLICATIONS 
       [0001]    The present application is related to U.S. Pat. No. 6,100,0273, filed Oct. 25, 2007, included by reference herein. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates to laser tape measurers and, more particularly, to laser tape measurers that can measure multiple values simultaneously. 
       BACKGROUND OF THE INVENTION 
       [0003]    Have you ever had the need to measure the height of a building, a pole, a tree, etc; or the distance between two points, both of which are some distance away from you? Maybe you are a builder and you are on the roof of your two-story house replacing some rafters. The piece of lumber beside you is eight feet (8′) long, but you need a piece that is seven feet (7′) long. You then noticed there are a couple of pieces of lumber on the ground; should you cut a foot (1′) off the piece you have (knowing that you&#39;ll need a piece eight feet (8′) long soon) or should you climb all the way down to the ground and measure the pieces there? You may climb all the way down only to find out that one measures 7′ 11″ and the other 8′ 1′. Now you discovered that you should have stayed up on the roof, and use the piece you had. Maybe you have been contracted to run a drain pipe all the way down the side of a 20-story building. Do you like others go to the top of the building, drop a line and then measure the line? These are real and challenging problem many have. 
         [0004]    My problem is this: through the back of my yard run the City&#39;s utility poles. My concern is whether or not the pole nearest to my house will hit the house if it breaks away at it&#39;s base. It seems so to me. It&#39;s my desire to solve this problem that has resulted in this invention. 
         [0005]    To date my research has yielded no product(s) which has attempted to solve any of the problems listed above. 
         [0006]    Conventional laser tape measurers will only measure the distance from your point of origin to another single point. 
         [0007]    It is therefore an object of the invention to provide the capability to measure the distance between two distant objects/targets. 
         [0008]    It is another object of the invention to measure the height of most objects, while aloof. 
         [0009]    It is another object of the invention to simultaneously measure the distance from your point of reference to two (2) separate objects. 
         [0010]    It is another object of the invention to simultaneously measure the combined distance from your point of reference to target  1 , from target  1  to target  2 , from target  2  back to your point of reference. 
         [0011]    It is another object of the invention to calculate any/all of the three angles created from your point of reference and the other two targets. 
       SUMMARY OF THE INVENTION 
       [0012]    In accordance with the present invention, there is provided a laser distance and angle calculator that will give three measured distances simultaneously; for example from Point A to B, Point A to C and Point B to C. It will also calculate the angle at each intersecting points. The angle at your point of reference is required, while the other angles are results of the calculation. 
         [0013]    As the laser control is turned on each side of the instrument, the corresponding laser rotates accordingly. As the laser on each side is pointed to their respective targets, the distances to these are captured. The lasers are optionally placed adjacent to each other or one above the other. The angle between these two points are also captured. With these pieces of captured data, the following calculation will be done:
       (a) the distance between the two targets   (b) the angle formed from
           (i) the Point of origin to Target # 1  to target # 2     (ii) the Point of origin to Target # 2  to target # 1     
               
 
         [0018]    This data will then be displayed on the LCD. This data can be cleared and the process repeated as often as desired.

       Head 
       [0030]    The head ( 12 ) is the compartment designed to house the lasers and optionally their controls. ( FIG. 2  shows the controls placed on the head ( 12 ) instead of the body ( 14 ).) The head ( 12 ) also has the capability to rotate 90 degrees in either direction up to the vertical position. This capability ensures that the Laser ( 16 ) 3-Point Distance and Angle Calculator can be maneuvered to measure horizontal, diagonal and vertical distances and angles. 
       Analog Protractor 
       [0031]    The optional Analog Protractor ( 26 ) will provide an approximate visual reading of the location of the lasers. It must be noted the laser ( 16 ) would have already been digitally calibrated in degrees; and decimal fractions of such. 
       Swivel 
       [0032]    The swivel ( 18 ) connects the head ( 12 ) to the body ( 14 ). It also allows the head ( 12 ) to rotate in either direction up to a vertical position (90 degrees). 
       Body 
       [0033]    The body ( 14 ) is the compartment designed to house all the other components not placed on or in the head ( 12 ). This figure shows the Laser ( 16 ) Controls, LCD ( 22 ) and Control buttons ( 24 ). Other obvious components like microcomputer, power supply etc, although not shown, will be housed here also.

       [0034]    The laser ( 16 ) is one of the key components of this Laser ( 16 ) 3-Point Distance and Angle Calculator. This figure shows the two ( 2 ) lasers placed adjacent to each other. These lasers will in some instances be placed one above the other, a decision which will be optional to a manufacturer. The laser ( 16 ) on the left is able rotate from its leftward-pointing horizontal position, through an arc of 90 degrees, up to the vertical position. The laser ( 16 ) on the right is able rotate from its rightward-pointing horizontal position, through an arc of 90 degrees, up to the vertical position. Each laser ( 16 ) may be configured to rotate from 0-180 degrees. The same result will/can be achieved in either case.

(2) The [right Laser ( 16 )] (RL) is rotated (using the right Laser Control ( 20 )) along a calibrated degree scale, and pointed on target number  2  (T 2 ). The degree reading along with the distance to T 2  is captured and stored by the Laser ( 16 ) 3-Point Distance and Angle Calculator&#39;s computing component.   (3) The angle between T 1  and T 2  is also captured. For the purpose of this document, this angle is referred to as “O” (see  FIG. 8 ). If each laser ( 16 ) is made to rotate through an arc of 180 degrees; and, the degree reading for the left laser ( 16 ) is greater than that of the right laser ( 16 ), then the absolute value for the difference in these two readings will be used in the calculation.   (4) The captured data is then be manipulated and the follow results will be displayed on the LCD ( 22 ):
       (a) The distance from your point of origin to T 1  (already captured in step # 1  above).   (b) The distance from your point of origin to T 2  (already captured in step # 2  above).   (c) The angle at your point of origin between T 1  and T 2  (already captured in step # 3  above).   (d) The distance between T 1  and T 2 .   (e) The angle created from your point of origin, to T 1  and then to T 2 . For the purpose of this document, this angle is referred to as “P” (see  FIG. 8 ).   (f) The angle created from your point of origin, to T 2  and then to T 1 . For the purpose of this document, this angle is referred to as “Q” (see  FIG. 8 ).   (g) The total distance (perimeter) from point O to T 1  to T 2 .

       Laser Control 
       [0112]    The right Laser Control ( 20 ) is used to rotate its respective laser ( 16 ) through its capable arc. The left Laser Control ( 20 ) is used to rotate its respective laser ( 16 ) through its capable arc. 
       Horizontal Water Level 
       [0113]    The Horizontal Water Level ( 28 ) is use to determine when the instrument is in a horizontal position. These are placed on both the top and side of the instrument to be utilized at the user&#39;s discretion. 
       LCD 
       [0114]    The LCD ( 22 ) will be used to display any or all of the data realized in step # 4 . Any other relevant information (like power level) may also be displayed here. 
       Control Buttons 
       [0115]    These are reserved for whatever functions the manufacturer deems necessary. Any or all of these buttons may be used. Additional buttons may be added as needed. 
         [0116]      FIG. 5  is a head ( 12 ) rotated 90 degrees to the left view, showing the head ( 12 ) with two ( 2 ) lasers atop each other. 
       Head 
       [0117]    The head ( 12 ) is the compartment designed to house the lasers and optionally their controls. ( FIG. 2  shows the controls placed on the head ( 12 ) instead of the body ( 14 ).) The head ( 12 ) also has the capability to rotate 90 degrees in either direction up to the vertical position. This capability ensures that the Laser ( 16 ) 3-Point Distance and Angle Calculator can be maneuvered to measure horizontal, diagonal and vertical distances and angles. The head ( 12 ) is shown here in its vertical position, after being rotated 90 degrees to the left. 
         [0118]      FIG. 6  is a head ( 12 ) rotated 90 degrees to the right view, showing the head ( 12 ) with two ( 2 ) lasers adjacent to each other.
