Abstract: A transmitter (200) generates (602) an encoded vector (404) by encoding (406) a data vector (402), the encoded vector representing payload information and parity information. The encoding is mathematically equivalent to calculating three or more forward error correction (FEC) codewords from the data vector and then calculating the encoded vector from the codewords, at least one codeword being calculated from at least one recursion of a mathematical operation, and at least one codeword comprising more than 6 terms. The transmitter transmits (604) a signal representing the encoded vector over a communication channel. A receiver (300) determines (702) a vector estimate (502) from the signal and recovers (716) the data vector from the vector estimate by sequentially decoding (706, 710, 714) the codewords, wherein at least one codeword that is decoded earlier in the decoding enhances an estimate of at least one codeword that is decoded later in the decoding.

Abstract: A process of compression molding an article from a curable resin is provided that includes opening a mold to an open position by displacing an upper die having an upper mold surface from a lower die having a lower mold surface. Resin is placed a mold surface and the dies are closed to an intermediate start position at a rate of from 1 to 10 cm/sec. The dies are then closed to a start position at a rate of between 25 and 60% of the rate of closure to the intermediate position. A shroud volume is evacuated for at least 3 seconds to a reduced pressure of less than 0.16 atmospheres while continuing to press toward a mold cavity volume at a rate of between 12 and 30% of the rate of closure to the intermediate start. The reduced pressure is removed as the full compression is applied.

Abstract: A preform for thermoset resin composition molding is provided that upon cure forms a variety of molded and fiber reinforced articles used in a variety of applications such as vehicle components including bed lines, body components, trim, interior components, and undercar components; architectural components such as trim and doors, marine components including hulls, trim, and cockpit pieces; and similar structures in aerospace settings. A novel slurry composition, a novel centrifugal process, or a combination thereof provide superior quality preforms that are created with greater throughput relative to conventional techniques. The inhibition of fiber movement between the time such a fiber contacts the mold, or fibers already in place on the mold, and the time the fibers are set in position provides a superior fiber homogeneity and randomized orientation relative to existing slurry techniques with attributes of low scrap generation, and process flexibility with respect to part shape and fiber material.

The digital instruction may be used by the transmitter to reduce the impairments. Alternatively, or additionally, the digital instruction may be used by the receiver of the optical communication system to compensate for the impairments.

Abstract: Described are an optical communications system and a method that allow for compensation of chromatic dispersion and polarization mode dispersion imparted to a communications signal propagating through an optical link. The system is based on a cost-effective optical transport architecture that accommodates baud rates exceeding 15 Gbaud and eliminates the need for costly optical dispersion compensators. Compensation for polarization mode dispersion is performed at the receiver using nonlinear processing. Advantageously, direct detection modulation using inexpensive electro-optic system components can be used in place of more costly and complex coherent and differential modulation formats. Digital filtering can be performed at the transmitter and the input signal can be inverted based on the nonlinearity of the transmitter electro-optic components. Consequently, the bandwidth and linearity requirements for the transmitter electro-optic components are relaxed, and cost reductions are realized.

The hydro-formed cross car reinforcement tube have flattened terminal ends with apertures for integrated attachment to a bolster. The hydro-formed cross car reinforcement tube is formed of aluminum, brass, carbon, steel, stainless steel, copper and high strength alloys.

Abstract: A signal equalizer for compensating impairments of an optical signal received through a link of a high speed optical communications network. At least one set of compensation vectors are computed for compensating at least two distinct types of impairments. A frequency domain processor is coupled to receive respective raw multi-bit in-phase (I) and quadrature (Q) sample streams of each received polarization of the optical signal. The frequency domain processor operates to digitally process the multi-bit sample streams, using the compensation vectors, to generate multi-bit estimates of symbols modulated onto each transmitted polarization of the optical signal. The frequency domain processor exhibits respective different responses to each one of the at least two distinct types of impairments.

Abstract: In a method of synthesizing an optical signal, a multi-bit digital representation of a desired optical E-field is generated. The multi-bit digital representation has a resolution of N1-bits, where N1 is an integer greater than 2. At least two analog drive signals are synthesized based on the multi-bit digital representation. Each analog drive signal exhibits excursions between 2M discrete states (i.e. has a resolution of M-bits), where M is an integer greater than 2. An electrical-to-optical (E/O) converter is driven using the analog drive signals to generate an output optical E-field at an output of the E/O converter. An error is detected between the output optical E-field and the desired complex E-field waveform, and at least one parameter adjusted so as to minimize the detected error.
