20110288812 | Apparatus and Method for Geometric Measurement - An non-contacting measurement apparatus for measuring distances, angles and related geometric quantities, and for computing other quantities based on the measurements, is provided. A visible light beam allows a user to point the device at one or more points to which the distance is measured, and angular rotation between the various points of interest can be recorded. Then, geometric and trigonometric relationships are used to compute and display lengths, areas, volumes or other facts derived from the measurements. Various input and output features are provided in the present embodiments. | 11-24-2011 |
