Abstract: At least one amplifier is selected from a first bank of non-linear amplifiers. At least one amplifier is selected from a second bank of non-linear amplifiers. The number of amplifiers selected from the first and second banks remains constant. Using the selected amplifiers, first and second components of a digital symbol are amplified using the first and second banks, respectively. The outputs produced by first and second banks are combined to produce an analog representation of the digital symbol.

Abstract: The present invention relates to a blade folding apparatus that may incorporate an overhead blade lifting system that reduces binding loads on blade pins induced by blade weight and pitch, and a folding mechanism that removes the necessity of personnel with external guide-poles to rotate main rotor blades. The apparatus may include flap locks, an overhead lifting system support structure attached to the flap locks, and two blade support beams to create and support a lifting point near each blade' s longitudinal and lateral center of gravity. The blade support beams may be fitted with an articulation mechanism that lifts and/or lowers the overhead lifting structure. The apparatus facilitates rapid folding of the main rotor blades, and, when used with blade clamping mechanisms, is capable of aiding in the removal and/or the re-installation of the main rotor blades without external lifting mechanisms.

Abstract: A method for cleaning a plurality of filters in parallel, each filter having an inlet side and an outlet side separated by a filter barrier. In an operational phase, water is filtered using a plurality of the filters, by passing the water through the filter, from the inlet side to the outlet side. These filters may be a hollow fiber membrane. In a cleaning phase, at least one of the filters is cleaned while the other filters are filtering water in the operational phase. Each filter is cleaned by supplying sodium hypochlorite to the inlet side of the filter when the filter is off-line. The inlet side of the filter is allowed to soak in the sodium hypochlorite for at least 30 seconds without the sodium hypochlorite being pressurized through the filter barrier during the soaking process. This oxidizes organic contaminates near the surface of the filter. The filters are cycled through the cleaning phase such that each filter is repeatedly cleaned while other filters are filtering in the operational phase.

Abstract: A method and apparatus for decoding forward error correction (FEC) encoded data. A stream of units of FEC encoded bits are received, where the units are derived from a transmitted signal, where each unit represents a one-bit data value, and where each unit includes correctness bits that together reflect a level of probability that the one-bit data value represented by the unit differs from corresponding bits in the signal before it was transmitted. The stream of units of FEC encoded bits are decoded by using the quality level of bits to perform soft-decision convolution decoding on the stream of units of FEC bits, where the soft decision convolution decoding produces, for block decoding, a stream of symbols made up of bits. In the stream of units of FEC bits, subsequences of units that are prone to erroneous soft-decision convolution decoding are detected by determining, for the sub-sequences whether the distribution of quality bits indicate the units are below a threshold level of correctness, and by comparing characteristics of that distribution to a given set of characteristics predetermined to be prone to result in incorrect decoding. Among the symbols produced for block decoding, symbols containing one or more bits that correspond to units that were in subsequences detected to be prone to erroneous soft-decision convolution decoding are flagged or tagged, and thereby, errors in the stream of symbols may be soft-decision block decoded by erasing the flagged symbols.
