Abstract: An optical transmission system has been designed to optimize the use of the spectral emission range of rare-earth-doped fiber amplifiers. The system includes a wide band of channels in the spectral emission range of erbium-doped fiber amplifiers, which is split into two sub-bands, a low sub-band corresponding to the low end of the range and a high sub-band corresponding to the high end of the range. The two sub-bands are separately amplified and optimized, and then recombined without significant competition between the two sub-bands. In addition, an equalizing filter, such as a specialized Bragg filter or interferential filter, is applied to the low sub-band instead of the entire band of channels, thus greatly reducing any equalization need or unequalization effects.

Abstract: An implantable substrate sensor has electronic circuitry and electrodes formed on opposite sides of a substrate. A protective coating covers the substrate, effectively hermetically sealing the electronic circuitry under the coating. Exposed areas of the electrodes are selectively left uncovered by the protective coating, thereby allowing such electrodes to be exposed to body tissue and fluids when the sensor is implanted in living tissue. The substrate on which the electronic circuitry and electrodes are formed is the same substrate or “chip” on which an integrated circuit (IC) is formed, which integrated circuit contains the desired electronic circuitry. Such approach eliminates the need for an hermetically sealed lid or cover to cover hybrid electronic circuitry, and allows the sensor to be made much thinner than would otherwise be possible. In one embodiment, two such substrate sensors may be placed back-to-back, with the electrodes facing outward.

Abstract: There is provided an optical wavelength converter which allows the rapid and efficient shifting of information modulated on a light signal of one wavelength to a light signal of a second wavelength without the negative effects of noise and other disturbances which have proven to be problems in the prior art. The device splits a CW probe signal of a first wavelength into two components, which propagate with opposite orientations through a Kerr leg. Also propagating in the Kerr leg is a modulated drive signal at a second wavelength. These signals interact in the Kerr leg, and are recombined at an output coupler so as to create interference between the two probe components. An intensity modulated probe signal is output.

Abstract: A phase locked loop circuit includes an input comparator (2) capable of generating a deviation signal which can be used for driving an oscillator (5) so as to generate an output signal (CLKOUT) locked to the input signal. The oscillator (5) can operate according to a plurality of characteristics under the control of a control circuit (8) including searching circuits arranged to carry out a first search phase by scanning the family of characteristics admitted for the operation of the oscillator (5) by bands of progressively reduced width, according to a general, dichotomic procedure. Upon completion of this first search phase, additional circuits of fine search are destined to identify the optimum operating point, compensating possible fluctuations of the characteristics.

Abstract: A trefoil for a rotary kiln is provided that has at least three spoke-like refractory legs. Each one of the legs extends radially outwardly from a center of the trefoil; spans approximately from the kiln shell to the center of the kiln; is pre-formed outside of the kiln for installation as a single-leg unit; and has a mating surface that preferably is uniform and even, thereby lacking interlocking features. The mating surfaces of the legs abut one another at the kiln center to provide mutual support. An alignment member, such as a pair of longitudinal angles, are welded to the kiln shell to position the legs. A corresponding method of installing the trefoil is disclosed that includes positioning and shimming the first two legs at the 4 o'clock position and 8 o'clock position, and installing the third leg at the 12 o'clock position.

Abstract: An embodiment includes a gating device, a feedback device and a control device. Soliton pulses are received by the gating device, which detects and monitors a dispersive-wave between adjacent soliton pulses using a timing circuit. The timing circuit typically provides a gating signal offset in phase from the soliton pulses in order to trigger the gating device. Triggering the gating device allows the dispersive-wave to be accessed and monitored between adjacent soliton pulses. The feedback device, typically using detectors and processing circuitry, measures the energy of the soliton pulses and the energy of dispersive wave. The feedback determines a ratio of the energy levels as an indication of soliton-pulse transmission performance. The indication is provided to the control device as a feedback signal so that the control device can appropriately adjust characteristics of the soliton pulses and improve or optimize transmission performance.
