Abstract: A stabilized turf (10) particularly suitable for athletic fields includes a mat (18) interposed between upper (24) and lower (16) layers of growth media, the mat (18) having a horizontally disposed, substantially biodegradable backing (22) and generally upwardly extending non-biodegradable fibers (20) secured thereto, wherein the fibers (20) exten d above the upper layer (24) of growth media. Natural grass plants (26) extend upwardly above the upper layer (24), with the roots extending down through the backing (22) and into the lower layer (16). The mat (18) stabilizes root growth, particularly during initial grow in. The substantial biodegradability of the backing (22) results in a loss of all or most of its horizontal structural integrity within a predetermined time period. The backing (22) may be treated with a decomposition agent to control the predetermined time period. Aerating hel ps to reorient and distribute the non-biodegradable fibers (22) within a subsurface vertical band (22a) greater in vertical dimension than the fibers (22) themselves. The stabilized turf (10) can also be topdressed. Thus, this turf (10) is adapted to accommodate both aeration and topdressing, two well-recognized and advocated turf management practices.

Abstract: A nulling direct radiating array (30) that includes a main phased array (32) and a plurality of auxiliary arrays (70, 72, 74) symmetrically disposed about the main array (32). The main array (32) includes a plurality of antenna elements (34) and a beam forming system (56) that generates one or more channels made up of several pixel beams. The pixel beams from the main array (32) are connected to a pulling processor (108) along with the combined signal from the antenna elements (80) of the auxiliary arrays (70, 72, 74). An adaptive weighting network (112) and an adaptive weight generator (114) within the pulling processor (108) determine whether a jamming signal exists in the channel beam, and weight the pixel beams from the main array (32) accordingly to block the jamming signal. The auxiliary arrays (70, 72, 74) provide a wider beam aperture that is able to more narrowly define the null in the radiation pattern of the main array (32).

Abstract: The system has a transmitter (200), having a complete data packet which is divided into a number of data units (Dus) (200). The DUs (220) are encoded f or both error detection and error correction. Both the error correction and err or detection parity check bits are separately combined into one or more blocks. Thereafter, the DUs (220) and the block(s) containing the combined parity check bits are transmitted to the receiver (250). If the receiver (250) determines that a received DU (220) does not contain any errors, the error correction parity check bits for that DU (220) are generated and their effec t on the combined error correction parity check bits removed. Thereafter, the remaining error correction parity check bits, which now only contains information about the Dus (220) actually in error, are used to correct the erroneous Dus (220).
