Abstract: In one example, a door apparatus is described, having a door leaf (102) part including a first door leaf portion (104a) and a second door leaf portion(104b), and having a pivot mechanism (106) defining a pivot axis connected to the first door leaf portion. The second door leaf portion is slidably movable with respect to the first door leaf portion between a first position, in which the door leaf part extends a first distance from the pivot axis, and a second position in which the door leaf part extends a second distance from the pivot axis, the first distance being larger than the second distance, and the pivot mechanism is to enable the door leaf part to pivot about the pivot axis when the second door leaf portion is in the second position.

Abstract: A satellite system is packed into and transported via a backpack whereby the backpack integrally accommodates and supports the satellite antenna system as a single unit. The satellite antenna system expands or telescopes from the backpack as a complete working unit without the assembly of parts or minimal assembly such as the connection of cables. The backpack itself becomes the base to support the satellite antenna system in a stable position.
