Latest Patents

Venables' latest patents include a method for enhancing the durability of adhesively bonded aluminum structures. This invention addresses the hydration of aluminum oxide surface coatings to aluminum hydroxide, which can be inhibited by the presence of corrosion-inhibiting amino phosphonate compounds. Effective inhibitors, such as nitrilotris (methylene) triphosphonic acid, can be applied to aluminum substrates in concentrations of less than 50% by weight in aqueous solution, ideally ranging from 1 to about 500 ppm.

Another significant patent is for a pyroelectric detector designed to decrease susceptibility to vibrational noise. This detector consists of a wafer of pyroelectric material with a thin central region supported by a thicker rim. The central region features deposited electrodes that define active detecting regions, which may be oppositely polarized domains electrically connected in parallel or a continuous domain with active regions connected in series opposition. The design ensures that the rim is spaced at least one thermal diffusion length from either active region, providing enhanced performance.
