Abstract: An apparatus includes a containment vessel having an interior space configured to be sealed. The interior space is configured to receive at least one reservoir of liquid to be vaporized during a decontamination process. The apparatus also includes a base configured to be inserted into the interior space. The base is configured to receive one or more pieces of personal protection equipment to be heated and decontaminated within the interior space during the decontamination process. The base is configured to hold the one or more pieces of personal protection equipment above the at least one reservoir of liquid. The apparatus further includes a pressure-relief valve configured to be opened to release a pressure within the interior space. In some cases, the apparatus may include a filter configured to filter material passing through the pressure-relief valve.

Abstract: A system includes a containment vessel configured to receive and retain equipment to be decontaminated. The system also includes a solar reflector configured to reflect solar energy towards the containment vessel in order to heat the containment vessel. The system further includes end supports configured to receive and retain the solar reflector and the containment vessel. The system also includes a base having or coupled to multiple side supports, where each side support is configured to contact and support a corresponding one of the end supports. In addition, the system includes one or more semi-transparent solar shades configured to reduce the solar energy reaching the solar reflector and the containment vessel.

Abstract: An apparatus includes an isolation barrier configured to absorb electromagnetic energy. The isolation barrier includes multiple layers stacked on one another. Each of the multiple layers includes at least one dielectric material, at least one thin-film resistive material carried by the at least one dielectric material, and conductive strips in electrical contact with the at least one thin-film resistive material. The isolation barrier also includes vias through the multiple layers. Multiple ones of the vias are positioned along each of the conductive strips, and the vias electrically couple the conductive strips in the multiple layers to one another. The isolation barrier is configured to guide the electromagnetic energy through the multiple layers to enable absorption of the electromagnetic energy by the at least one thin-film resistive material.

CPC classification number: H01Q19/065 , H01Q1/38
Abstract: A planar conductive millimeter-wave lens includes: a planar conductive plate with a first surface and a second surface, wherein the first surface is parallel to the second surface; a plurality of openings from the first surface through the planar conductive plate to the second surface, where an axis of each opening is perpendicular to the first surface and the second surface. A size of each opening is a function of a position of said each opening on the planar conductive plate such that an insertion phase collectively imposed by the openings on an incident wave causes the incident wave to pass through the first surface and the planar conductive plate, exit from the second surface and to focus at a predetermined distance from the second surface.

Abstract: An armored radome includes an electrically-conductive ground plane that provides load bearing and/or ballistic protection to a shielded sensor, and a pair of radiator structures on opposing surfaces of the ground plane. The radiator structures each include an antenna, and the ground plane includes one or more coaxial feedthroughs that couple the antennas for reradiation of signals. One or both of the radiator structures may include a frequency-selective surface (FSS) according to a desired operating frequency range or to shape a frequency response of the radome. The disclosed radome is both mechanically strong, and electromagnetically transparent, or nearly so, across a wide range of frequencies and transmit/receive angles.

CPC classification number: G01D11/245 , G01D11/26
Abstract: A multi-axis self-contained sensor system includes an outer spherical housing and an inner spherical housing. The outer spherical housing has a transparent spherical shell that surrounds a first cavity and having a first refractive index (RI). The inner spherical housing is in the first cavity and is completely surrounded by the outer spherical housing. The inner spherical housing has a first average density and includes a spherical wall that surrounds a second cavity. A sensor system is contained in the second cavity, and a suspending fluid layer is interposed between the outer spherical housing and the inner spherical housing. The suspending fluid layer is composed of a fluid having a second RI.

Abstract: In one aspect, a Y-splitter includes a first arm having a first port, a second arm having a second port, a third arm having a third port, a fourth arm having a fourth port and a Y-split portion having a first end coupled to the first arm, a second end coupled to the second arm, a third end coupled to the third arm and a fourth end coupled to the fourth arm. The Y-split portion splits a signal from a first signal path from the first port into a second signal on a second signal path and a third signal on a third signal path. A first angle between the second signal path and the first signal path is greater than 90 degrees and a second angle between the third signal path and the first signal path is greater than 90 degrees.
