Patents and Licenses

Materials for Light-Weight Armor
U.S. Patent 6,357,332 was issued for MAE Professor Kenneth Vecchio’s method for making metallic/intermetallic composite laminate materials that are damage tolerant and capable of defeating rifle-fired, armor-piercing rounds of ammunition. These materials are ideal for use as aircraft, watercraft and vehicle armor and have applications in both military and civilian arenas. The process for creating the materials is inexpensive, simple to perform and control, and uses readily available components. The microstructure and mechanical properties of the materials have been characterized and preliminary prototype testing has been performed. The technology is available for licensing. Reference SD1998-065.

Extending Lifetime of Spacecraft Engines
UCSD inventors have designed a method to dramatically increase the life span of satellites and other space craft employing Molybdenum grid based Ion Thruster Engines. The proposed method will reduce erosion of the Molybdenum grid by as much as 10-fold, thereby increasing the life of the engine by an equal margin. This method may be further developed to reduce the mass of current Molybdenum Grid designs without compromising performance, thus reducing the weight of the overall engine and improving launch efficiency. The invention is available for licensing. Reference SD2002-088.

Light Modulator Arrays
UCSD recently received U.S. Patent 6,396,618 for Professor Sadik Esener’s method to create an improved light modulator array formed with opposing electrodes which extend away from the optic surfaces of optoelectronic material used to form the array. Crosstalk due to strain birefringence between array elements is reduced or eliminated. The electric field is applied across the electrooptic modulator material rather than parallel to one of the array's optical surfaces. This extends the interaction length of light with the electrooptic material under the influence of the field to the full width of the material rather than being limited to a thin surface layer. The longer interaction length allows for an increase in contrast ratio and a decrease in the necessary applied voltage. The technology has been licensed to Creoscitex Corporation, Ltd.
