  • Patent number: 11912440
    Abstract: A solar array structure, such as for a spacecraft, uses thin solar array panels that, when in a stowed configuration, are stiffened by being bent or curved in one direction to be shaped like a section of a cylinder and placed within a rigid structural frame. As a curved solar panel is not as efficient as a flat panel directly facing the sun, the solar array panels are curved in their stowed configuration for launch only, but flatten after deployment by use of a partially flexible structural frame, where a rectangular frame is made of two opposing rigid sides and two opposing flexible sides, with a thin flexible solar panel attached to rigid sides only. The rigid sides are compressed during stowage to curve the panel before hold-down tensioning. The structure and panels return to their flat free state configuration after release.

  • Patent number: 11873073
    Abstract: Phased array antennas, such as a multi-function aperture, are limited in performance and reliability by traditional air-cooled thermal management systems. A fuel-cooled multi-function aperture passes engine fuel through heat exchangers that surround the multi-function aperture to provide better heat transfer than can be achieved through air cooling systems. The increased heat transfer and thermal management results in a multi-function aperture with improved performance and reliability.

  • Patent number: 11754706
    Abstract: A system and method for applying an adaptive adjustment or taper to an electronically scanned array (ESA) weather radar based on feedback from the weather radar. To minimize ground clutter and enable the ESA to display hazardous weather phenomena, the system adaptively adjusts amplitude and phase of ESA elements to adjust the far field pattern shape and sidelobes to maintain a desirable signal to clutter ratio. The system identifies ground clutter as a strong ground return over several azimuths depending on the radar beamwidth. Once the system IDs the ground clutter, it adaptively adjusts on receive for for the upcoming azimuths. The system selectively suppresses sidelobe echoes while maintaining the signal to noise (SNR) for weather targets. The system adaptively adjusts in real time as well as adjusting using precomputed historically accurate tapers stored in memory.

  • Patent number: 10749249
    Abstract: Aspects of the present disclosure are related to digital display devices and base stations such as small cell base stations, which may include at least one antenna and a radio. More specifically, digital display devices are being increasingly deployed in airports, along roads and highways, in shopping malls, in rural or highly urban areas where additional cellular coverage is desirable. These digital display devices provide desirable mounting locations for cellular equipment because they are already powered. One or more components of the base station may be concealed from view by a concealment device to satisfy aesthetic or design requirements. In some aspects, this concealment device may be a fabric radome. In some aspects, the concealment device may be the digital display device itself, because the digital display device is dimensioned such that at least some components of the base station may be hidden behind or within the digital display device.
