Latest Patents

Among his latest contributions to technology are two significant patents:

1. **Polymer-Dispersed Liquid Crystal Device**

This invention describes a polymer-dispersed liquid crystal device, which contains numerous droplets of birefringent, functionally nematic liquid crystal material dispersed within a matrix formed by the reaction of ultraviolet radiation polymerizable materials. The device's unique feature is its ability to specularly transmit incident light based on the strength of the electric field applied. Notably, the difference between the first and second applied voltages correlating to various percentages of total incident light transmitted must exceed 15 volts, allowing for a variable grey scale with uniform optical transmission.

2. **Antistatic X-ray Intensifying Screen**

Huffman's work in X-ray technology led to the development of an intensifying screen that includes a support structure, a fluorescent layer with phosphor particles, and a protective top-coat layer. This innovative screen is characterized by incorporating salts such as fluoroalkylsulfonyl methides in either the fluorescent or the top-coat layers, significantly enhancing its performance in medical imaging applications.
