Machine learning (ML) is a field of study in artificial intelligence concerned with the development and study of statistical algorithms that can learn from data and generalize to unseen data, and thus perform tasks without explicit instructions. Recently, artificial neural networks have been able to surpass many previous approaches in performance.
The AN/SEQ-3 Laser Weapon System or XN-1 LaWS [1] is a laser weapon developed by the United States Navy. The weapon was installed on USS Ponce for field testing in 2014. In December 2014, the United States Navy reported that the LaWS system worked perfectly against low-end asymmetric threats, and that the commander of Ponce was authorized to ...
In roof prism designs, optically relevant prism angles must be correct within 2 arcseconds (1 / 1,800 of 1 degree) to avoid seeing an obstructive double image. Maintaining such tight production tolerances for the alignment of their optical elements by laser or interference (collimation) at an affordable price point is challenging.
Multiaxis machining. A 5-axis water jet cutter and a part manufactured with it. Multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting.

Wedge prism. The wedge prism is a prism with a shallow angle between its input and output surfaces. This angle is usually 3 degrees or less. Refraction at the surfaces causes the prism to deflect light by a fixed angle. When viewing a scene through such a prism, objects will appear to be offset by an amount that varies with their distance from ...
A mimeograph machine (often abbreviated to mimeo, sometimes called a stencil duplicator or stencil machine) was a low-cost duplicating machine that worked by forcing ink through a stencil onto paper. [1] The process was called mimeography, and a copy made by the process was a mimeograph . Mimeographs, along with spirit duplicators and ...
A Hieronymus machine is any of the patented radionics devices invented by electrical engineer Thomas Galen Hieronymus (21 November 1895 – 21 February 1988). Hieronymus received a U.S. Patent for his invention in 1949, which was described in the patent application title as a device for "detection of emanations from materials and measurement of ...
