Abstract: A feed network for an antenna system, e.g., a phased array antenna system, which is operatively associated with a signal source, e.g., satellite-based transponders, which generates first and second R.F. signals of circular polarization, and third and fourth R.F. signals of orthogonal linear polarizations. The feed network includes a 3dB hybrid coupler or the like for splitting each of the first and second R.F. signals into first and second signal components disposed in phase quadrature with each other. Facilities are provided for applying the first signal components of the first and second R.F. signals, and the third R.F. signal, to a first beam forming network (BFN); and, for separately applying the second signal components of the first and second R.F. signals, and the fourth R.F. signal, to a second BFN. Subsequent to their emergence from the BFN's, the first and second signal components of each of the first and second R.F. signals are applied to respective through and side ports of ortho-mode-tees (OMT's) which function to re-combine the first and second signal components, in phase quadrature, in order to thereby produce output first and second R.F. signals of opposite-sense (i.e., dual) circular polarizations. The third and fourth R.F. signals pass unaffected through the OMT's as output third and fourth R.F. signals of orthogonal (i.e., dual) linear polarizations. The first, second, third, and fourth output R.F. signals are then fed through common transmission lin?? to excite the individual antenna elements of the antenna system.      In an alternative embodiment, the feed network has an architecture which is virtually identical to that of the preferred embodiment described above, except that pin polarizers or the like are provided between the OMT's and the antenna elements. However, in the alternative embodiment, the first and second R.F. signals are of orthogonal linear polarizations, and the third and fourth R.F. signals are of opposite-sense circular polarizations. The first and second signal components of the first and second R.F. signals are re-combined at the OMT's to produce intermediate first and second R.F. signals of opposite-sense circular polarizations. The pin polarizers function to convert the intermediate first and second R.F. signals to orthogonally linearly polarized output first and second R.F. signals. The first, second, third, and fourth R.F. signals of both of the above-described embodiments preferably occupy different frequency bands.

Abstract: A method of controlling data sending and receiving operations between two microprocessors.  A first controlled-side microprocessor receives an optional one of a data sending request signal and a data receiving request signal from a second controlling-side microprocessor.  The first microprocessor also receives a select signal of a logic OR signal of both request signals, and determines if the optional one request signal indicates "receiving request" or "sending request" at the same time when it responds to the select signal, thereby executing the requested operation.          Hence, even if the first microprocessor does not receive the select signal and the sending/receiving signal at a time, the first microprocessor can determine simulta-neously with the receipt of the select signal if it should send or receive the data, resulting in a higher-speed data processing.
