  • Patent number: 10315538
    Abstract: A child safety seat includes a seat shell, an extension member and a foot. The seat shell has a bottom surface capable of resting stably on a vehicle seat. The extension member is connected with the seat shell, and is configurable between a first position where a forward end of the extension member extends forward from a front end of the seat shell, and a second position where the extension member is retracted toward the seat shell. The foot is connected with the seat shell and is disposed adjacent to the bottom surface of the seat shell, the foot being movably linked to the extension member. The foot and the seat shell are movable relative to each other to adjust the seat shell between at least a first and a second angular position, the second angular position being reclined rearward relative to the first angular position.

  • Patent number: 8059057
    Abstract: According to one embodiment of the present invention, a microwave or millimeter wave module includes a dielectric layer having a pocket formed substantially through the dielectric layer. The dielectric is attached to a metal substrate. The pocket has substantially vertical sidewalls. An integrated circuit is disposed in the pocket. Opposing sides of the integrated circuit are substantially parallel to the sidewalls of the pocket.
