Title: Method and system for the transmission, reception and processing of 4-level and 8-level signaling symbols
Inventor: DENT PAUL W
IPC: H04L27/20
Filed: 1999-11-24
Abstract: A method and system for the transmission, reception, and processing of 4-level and 8-level signaling symbols is provided. An inventive modulator is provided for modulating 4-level signaling symbols using an 8-level modulator. Further, this inventive modulator is able to produce 4-level modulation when modulating 4-level signaling symbols using an 8-level modulator, where the 4-level modulation represents the 4-level symbol sequence modulated. Further, a constrained/unconstrained demodulator is provided which is able to demodulate both 4-level signaling symbols and 8-level signaling symbols. The inventive demodulator accomplishes this by limiting the number of new symbol hypotheses and path histories to 4 when working with 4-level signaling symbols, and setting the number of new symbol hypotheses and path histories to 8 when working with 8-level signaling symbols. Additionally, an error correction decoder is provided which is also able to decode a demodulated signal which contains both 4-level and 8-level signaling symbols. The inventive error correction decoder accomplishes this by utilizing an interleaver that only places bits in the 2-bit positions of the 3-PSK soft values that correspond to the 2-bits of QPSK to decode 4-level signalling symbols, and utilizing an interleaver that places bits in all three of the possible bit positions of a symbol to decode 8-level signalling symbols.

Abstract: PCT No. PCT/EP92/01462 Sec. 371 Date Aug. 18, 1992 Sec. 102(e) Date Aug. 18, 1992 PCT Filed Jun. 29, 1992 PCT Pub. No. WO93/01647 PCT Pub. Date Jan. 21, 1993.An apparatus moves, for example with a rotative motion, a member or a first group of members by moving another member or a second group of members with a reciprocating rectilineal motion by the interaction between magnets (1, 2) or groups of magnets (1i, 2i) fixed to the members or the group of members. If the reciprocating rectilineal motion is obtained by connecting one of the two groups of magnets to pistons of a two-stroke engine and to a mechanical energy-restoring system (8), a high-efficiency apparatus is realized, which is suitable for engine-traction, which does not need a crank-shaft, a lubricating system, a water cooling system, an alternator, or a torque converter, and which is automatically switched off when the vehicle is not in motion. The work-torque can be varied by varying the distance between the restoring system (8) and the supporting members (14) which are connected to the pistons (5). Easy and cheap to make, this apparatus causes little pollution and is suitable even for using hydrogen as a fuel. In this case, its pollution products are insignificant or equal to zero.

Patent AU-4332697-A (AU)
Title: Microbial remediation reactor and process
Inventor: STORMO KEITH E
IPC: B01J19/18
Filed: 1997-09-03
Abstract: Embodiments of a remediation reactor and mixer/contactor blade for the reactor are shown and described, the reactor being for containing a liquid slurry, suspension or settled bed of solid particles containing microorganisms. Inside the vessel is a supply conduit and at least one generally horizontal stirrer blade in fluid connection with the supply conduit. The stirrer blade is a mixer/contactor which has a leading side having openings through which fluid may pass. The stirrer blade rotates in the vessel, and this rotation is made easier by the hydraulic forces of fluid flowing out from the stirrer blade. The flowing fluid creates a fluidization zone in the slurry, suspension or settled bed at or near the leading edge of the stirrer blade. The fluidization zone is less dense than the rest of the sediment bed, and the stirrer blade tends to rotate into the fluidization zone. This way, controlled rotation of the stirrer blade may be created near the bottom of the vessel, enhancing mixing of the microorganisms with the slurry, suspension or settled bed in the vessel, without unnecessarily damaging the microorganisms, especially when the flowing fluid contains contaminants which are nutrients for the microorganisms. Also, shown and described is a vessel which incorporates a mixing blade through which a gas and/or a liquid is recirculated. The mixing blade is rotated through a sand layer or other settled bed of solid particles, which acts as a medium supporting microbial growth and/or as a filter to remove particulate matter from the vessel effluent which is drawn off from below the settled bed layer. Fluid recirculation aids in the fluidization of the filter medium and allows for intermittent operation with a significant reduction in energy and operating costs. The vessel may be operated as an aerobic bioreactor by recirculating air or as an anaerobic bioreactor by recirculating an inert gas.
