  • Patent number: 8406761
    Abstract: A device includes a first type of cellular capability for connecting to a first cellular network and a second type of cellular capability for connecting to a second cellular network. The device terminates advertising of the first type of cellular capability after determining that the device is not initialized. The device also transmits a request to the second cellular network by using the second type of cellular capability; receives a name of a carrier, associated with the device, from a server and via the second cellular network; and initializes the device based on the name of the carrier.

  • Patent number: 4109589
    Abstract: A glass top table has pivotally supported end leaves mounted between spaced side frames for movement between an inwardly projecting storage position and an outwardly projecting use position. Each side frame has an upper frame member and a pair of legs projecting downwardly from opposite ends of its upper frame member. A glass table top extends laterally between the upper frame members and is located above the end leaves in their storage position and in alignment therewith in the use position. Each end leaf includes a peripheral rectangular frame which is elongated in a lateral direction and a glass leaf secured to the rectangular frame. A pair of support frame members extend laterally between the upper members of the side frames and are located adjacent the end leaf frames in the storage position thereof so as to provide an aesthetically appealing appearance.
