  • Patent number: 11726169
    Abstract: A system for augmenting 360-degree aspect monostatic radar cross section of an aircraft. The system may comprise a pair of pods mountable on opposing wing tips of an aircraft and each having a pod housing with an elongate body tapering forwardly to a nose and rearwardly to a tail. Each pod may comprise a forward SDL disposed within the nose, a rear SDL disposed within the tail, and a pair of mid-body SDLs disposed within a mid-section of the pod housing. The SDLs may be arranged within the pods to reflect radiation and provide coverage around the aircraft over a region of about 360 azimuth degrees. Each SDL may comprise radar absorbing material located on an interior reflective surface, and portions of the elongate bodies may be constructed of radome material. The SDLs may be Luneburg lens having diameters of at least approximately 8-inches.

  • Patent number: 8892827
    Abstract: A method and an apparatus for selecting one or more applications running in a data processing system to reduce memory usage according to information received from the applications are described. Notifications specifying the information including application specific memory management capabilities may be received from the applications. A status of memory usage indicating lack of available memory may be determined to notify the selected applications. Accordingly, the notified applications may perform operations for application specific memory management to increase available memory.

  • Patent number: 5435806
    Abstract: This diaper comprises at the level of each of its transverse edges, a strip of open cell foam material extending transversely with respect to the diaper and fixed between the support and upper sheets of the latter. These elastic strips are designed to come into elastic contact with the body of a user at the level of the latter's waist. The longitudinal inner and outer edges of each strip communicate respectively with the inner space of the napkin and with the outside of the latter to permit this inner space to communicate thus with the outer space through the thickness of the strips so as to permit the internal ventilation of the napkin.

  • Patent number: 4091337
    Abstract: An adjustable feedback in a pencil tube oscillator is provided by a pick-up element closely spaced from the center conductor of the output cavity of the oscillator with the pick-up element connected via a short length of rigid conductive wire to the cathode electrode in the input cavity. This pick-up element is a thin sheet of deformable conductive material fixed to the end of the rigid wire in a manner that permits the sheet to be easily bent toward or away from the center conductor to accommodate adjustment of the feedback coupling capacitance.

  • Patent number: 4051447
    Abstract: An output coupler for a radio frequency oscillator includes a coaxial transmission line connector having a center conductor terminating in a coulping loop in the oscillator, the terminated end of the loop being secured to the cavity wall of the oscillator. Both the magnitude and depth of penetration of the loop are concurrently adjustable without altering the orientation of the loop by sliding the transmission line and center conductor with respect to the cavity wall. When optimum coupling is achieved, the transmission line connector is clamped in place.

  • Patent number: 4034320
    Abstract: An output coaxial cavity for high power electron tubes is described in which the output coupler is directly connected to an intermediate coaxial conductor of the coaxial cavity at a distance from the tube that is greater than one-quarter wavelength and less than one-half wavelength over the tuning range of the cavity. The intermediate coaxial conductor is spaced between and concentric with an inner conductor and an outer conductor of the coaxial cavity. A first shorting stub is positioned between the inner conductor and the intermediate conductor and a second shorting stub is coupled between the intermediate conductor and the outer conductor. The positions of the shorting stubs are arranged to resonate the cavity at the desired tuning frequency.
