Abstract: A system for simulating quadrature phase-shift key (QPSK) beam forming in an antenna array, including a transmitter configured and operable to generate an oscillating signal, an antenna array, a binary phase shifter associated with each transmitting antenna, the binary phase shifter configured and operable to selectively apply a phase shift of 180 degrees to the transmitted signal, and a controller configured to send instructions to the binary phase shifters, at least one receiving antenna, and a post processor comprising a memory operable to save received signals and a processing unit operable to apply a 90 degree phase shift to selected received signals stored in the memory, and further operable to sum received signals stored in the memory, operable to manipulate received signals.

Abstract: A package for holding media discs is disclosed, having a hinged tray assembly that includes at least two transparent disc-holding trays each having a hinge edge and means for securing a media disc to the tray, the trays being constructed such that the disc securing means of each tray is positioned offset with respect to the disc securing means of adjacent trays such that when the tray assembly is in a closed configuration, the trays are arranged in a stack with hinge edges lined up and each disc securing means being offset from the disc securing means of adjacent trays in the stack, the trays being hinged to each other. The package can also include a jacket with a plurality of panels folding around the tray assembly to close the package.
