Abstract

A laser leveler includes an ultrasonic transmitter, an ultrasonic receiver and a computer for computing distances traveled by an ultrasonic signal emitted from the ultrasonic transmitter and reflected back to the ultrasonic receiver.

Claims

1. A laser leveler comprising an ultrasonic transmitter, an ultrasonic receiver and a computer for computing distances traveled by an electronic signal emitted from the ultrasonic transmitter and received by the ultrasonic receiver.

2. The laser leveler of claim 1 further comprising an LCD screen adapted to display distances calculated using ultrasonic signals sent from the ultrasonic transmitter and received back from the ultrasonic receiver.

3. The laser leveler of claim 1 wherein the computer is adapted to calculate area measurement from distance calculations in two directions disposed at right angles.

4. The laser leveler of claim 1 wherein the computer means is adapted to calculate area measurement from distance calculations in three directions, each disposed apart from one another by an angle of 90°

.

5. The laser leveler of claim 1 wherein the computer is capable of toggling back and forth between at least two different linear measurement systems.
