Abstract
A device for measuring physical characteristics includes a beam generator component generating first and second beams at two points. The device further includes a protractor that measures the angle between the beams. The device measures the distances to the two points and with the angle between the two beams, determines a predetermined characteristic, such as the distance between the two points.
Claims27
A device for measuring the distance between two arbitrary points comprising:
- means for determining two reference distances between a reference point and the two arbitrary points, said means for determining including a first beam generator generating an invisible beam selectively directed from said reference point to one of said arbitary points and a second beam generator generating a visible beam corresponding to said invisible beam to enable a user to target said invisible beam;
- means for determining a corresponding angle;
- and
- means for calculating the distance between the points from said reference distances and said corresponding angle.

A measuring device comprising:
- a beam generator that generates a beam;
- a pivoting mirror selectively directing said beam at a first and a second arbitrary point,
- an angle sensor that provides the angle between the first and a second arbitrary point;
- and
- a calculator using at least a distance associated with said beam and said angle to determine a physical characteristic associated with said arbitrary points.

A device for measuring the distance between a first point and a second point comprising:
- an image generator disposed at a reference point generating an image of a line having a first end and a second end, said line having a variable length;
- a distance detector that determines a first distance between the reference point and the first end, and a second distance between the reference point and the second end;
- an angle detector that determines an angle between said ends as defined from said reference point;
- and
- a calculator that calculates the distance between said first and second ends from said first distance, said second distance and said angle.
