Title: **Innovations by Thomas M. Knasel: Advancements in Vessel Navigation Lighting**
Introduction
Thomas M. Knasel, a distinguished inventor located in McLean, VA, has made significant contributions to the field of vessel navigation lighting. With a portfolio of three patents, Knasel has focused on developing optical elements that improve safety and efficiency in maritime navigation.
Latest Patents
Knasel's latest patent focuses on innovative optical elements for vessel navigation lights. These elements provide an improved and cost-effective means of achieving uniform luminous intensity over a sharply defined horizontal arc of visibility. Additionally, the innovation allows for the creation of a desired vertical arc of visibility. The design incorporates mechanisms to project light from diffuse sources, or arrays of point sources, into fields with precisely defined horizontal and vertical arcs. Two geometric configurations, symmetrical and asymmetrical, using compound parabolic concentrators, have been developed. Each configuration can either be a reflective cavity or a refractive dielectric, resulting in four basic designs aimed at achieving uniform illumination across various horizontal arcs. Moreover, the patent describes three modes of diffuse light projection for consistent vertical illumination. The precision of these optical elements ensures full compliance with the stringent visibility specifications established by the Final Act of the International Conference on Revision of the International Regulations for Preventing Collisions at Sea, 1972 (72 COLREGS), and the International Rules of Navigation Act of 1977, 33 U.S.C. 1601, all while being cost-effective.
