Latest Patents

Among his latest patents, Richard has developed "Micro-emitters for electrospray systems." This patent introduces micro-emitter arrays that can be microfabricated to include multiple emitters with heights exceeding 280 microns, maintaining a uniformity of ±10 microns. These emitters are structured on a silicon substrate, featuring an elongated body that extends from the top surface and incorporates at least one emitter tip. The configuration allows for an ordered array in an X by Y grid pattern, suitable for various applications using LMIS propellant sources, including materials like gallium, indium, bismuth, or tin. Furthermore, his invention includes a substrate design with through-vias that create a fluid pathway for the propellant, enhancing the efficiency of the micro-emitter arrays.

Another key patent is for a "Diffractive optical fluid shear stress sensor." This innovative sensor operates by generating diverging fringes across a linear measurement area. Utilizing a diode laser, the device focuses light onto a diffractive lens that allows the light to reach slits, creating the diverging fringes. Scattered light from these fringes is collected by a window and refocused through another diffractive lens to a receiver, enabling precise measurements of shear stress in various fluid dynamics applications.
