Latest Patents

Johnson holds a patent for a "Hyper hemisphere unitary dome for a defensive infrared countermeasure system." This invention features a unitary infrared transparent dome with a look angle greater than 180 degrees. The dome consists of two hemispherical regions, with the second region having a truncated bottom end that defines an opening to a central cavity. Inside this cavity, electro-optical elements are strategically placed to view outward through the dome. The design ensures that the second region of the dome has a complementary curvature to the first region, maintaining a consistent radius beyond the transverse horizontal axis. The dome is mounted to a base, which defines a rabbet extending circumferentially about the base's imaginary center, creating an aperture. Notably, the dome and base are made from different materials, yet they possess equivalent coefficients of thermal expansion. In one embodiment, the dome is crafted from sapphire, while the base is made of titanium. This innovative design enhances the operational capabilities of defensive systems.
