Hand-held measuring device
First Claim
1. A portable, hand-held measurement device, comprising:
- transmitter means to transmit a signal at a target object;
receiver means to receive a reflection of the signal reflected from the target object;
processor means operably coupled to the transmitter and receiver means to obtain a measurement value, the processor means having storage means for storing pluralities of the measurement values and calculation means for calculating areas and volumes from the stored pluralities of measurements;
display means coupled to the processor means for selectively displaying the measurement values and calculated areas and volumes; and
viewfinder means for aiming the device at a target, the viewfinder means being disposed so as to project the target image onto the display means.

Abstract
A hand-held, portable, simple to use, low-cost yet accurate measurement device for measuring distances and calculating areas and volumes. The device comprises a microprocessor-controlled transmitter/receiver combination for transmitting measuring signals, and receiving reflections of those signals to provide distance or length measurements. The microprocessor operates to store sequential measurements and to calculate areas and volumes therefrom. The measurement procedure involves aiming the device and operating a simple sequence of buttons to obtain the measurements. Additional features of the device include a target and stand to reflect the measuring signals, a viewfinder, a level meter, and an indented rear portion with flush sides to place the device against a vertical surface for measuring, and a generally flat surface to place the device on a horizontal surface for measuring.
