  • Patent number: 10431904
    Abstract: An antenna array assembly comprises a dielectric film (2) carrying an array of conductive patch radiator elements (7) and a plurality of conductive feed tracks and a ground plate (1), a face of the ground plate (1) having a contoured shape comprising a first part configured to be in contact with the dielectric film (2), and a second part comprising sunken sections with respect to the first part arranged to underlie the conductive feed tracks and conductive patch radiator elements (7), and the ground plate having locating protrusions (6g, 6f) protruding from the first part. The dielectric film is attached to the ground plate by location of holes in the dielectric film with the locating protrusions (6g, 6f) such that the dielectric film is held under tension to maintain spacing of the dielectric film (2) from the sunken sections of the ground plate (1) without the use of a dielectric spacer layer between the dielectric film (2) and the ground plate (1).

  • Patent number: 9025784
    Abstract: Aspects for monitoring audible tones indicative of operational status of each planar in a multiple planar chassis are described. Included in the aspects is the monitoring of a speaker channel of each planar of a plurality of planars in a common chassis for state changes of beep tones.

  • Patent number: 8140705
    Abstract: A method and system for recovering a server blade, in a multiple server blade computer, that is lost during a flash update operation on a service processor in the server blade. Because of the flash update failure, the lost server blade is unaware of its location on a management pathway, which in an exemplary form may be a midplane or a bus, which connects the server blade and a management module in a server blade chassis. The lost server blade puts a signal on the management pathway indicating that the flash failed. The signal is put on a special channel reserved for such messages. The management module receives the signal, and then determines which of the multiple server blades are lost due to the flash update failure.
