Abstract: Register banks are used to allow for fast beam switching in a phased array system. Each beam forming channel is associated with a register bank containing M register sets for configuring such things as gain/amplitude and phase parameters of the beam forming channel. The register banks for all beam forming channels can be pre-programmed and then fast beam switching circuitry allows all beam forming channels across the array to be switched to use the same register set from its corresponding register bank at substantially the same time, thereby allowing the phased array system to be quickly switched between various beam patterns and orientations. Active power control circuitry may be used to control the amount of electrical power provided to or consumed by one or more individual beam forming channels such as to reduce DC power consumption of the array and/or to selectively change the effective directivity of the array.

Abstract: A container includes a box comprising a bottom wall and four side walls. Each of the side walls is pivotably connected to the bottom wall. Each of the side walls has at least one bore that mates with at least one bore in an adjacent side wall when the box is folded into shape. An insert has a bottom wall and two side walls. Each of the insert side walls has at least one bore that mates with the at least one bore in the box side walls. A fastener extends through each of the mating bores in the box side walls and the insert bores to maintain the shape of the box and to maintain the position of the insert within the box. Another container includes a box comprising a bottom wall and four side walls. Each of the side walls is pivotably connected to the bottom wall. Two of the side walls each have a pair of flaps that are pivotably connected to the side wall on opposite edges. Each of the flaps has an inwardly facing surface and an outwardly facing surface.
