Patent number: 10677567Abstract: A transparent composite armor is made of tens to hundreds or even thousands of thin layers of material each with a thickness of 10-500 ?m. An appropriate amount of impedance mismatch between the layers causes some reflection at each interface but limit the amplitude of the resulting tensile wave below the tensile strength of the constituent materials. The result is an improvement in ballistic performance and that will result is a significant impact in reducing size, weight, and volume of the armor.Type: GrantFiled: April 26, 2017Date of Patent: June 9, 2020Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Guillermo R.

Patent number: 9469806Abstract: Method of Making particles including a YAG core and a coating of sintering aid deposited thereon. The particles and agglomerates thereof maybe formed as a powder. The coated YAG-containing particles are well-suited to production of polycrystalline YAG-containing ceramics. The coated YAG-containing particles may be fabricated using a novel fabrication method which avoids the need for formation of a homogeneous powder mixture of YAG and sintering aid. The mixture may be sprayed into a drying column and dried to produce coated particles. Alternatively, the YAG particles and sintering aid or sintering aid precursor solution may be separately introduced to the drying column and dried to form coated YAG-containing particles.Type: GrantFiled: December 6, 2012Date of Patent: October 18, 2016Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Guillermo R.
