Patent EP-0477021-A2 (EP)
Inventor: FIDRIC BERNARD G
IPC: H01S3/0941
Filed: 1991-09-19
Abstract: A wavelength stabilization apparatus (10) and method for a superfluorescent source comprising a SFS (superfluorescent source) comprising a fibre with a core doped with lazing material. The SFS source produces SFS light with an SFS wavelength when pumped with pump light from a pump light source (14) having a pump light wavelength. An output controller responds to a sample of the SFS light and operates to maximize the power of the sample of SFS light by automatically adjusting the pump light wavelength. The output controller also has a pump power controller (27) responsive to a sample of the pump light from the pump light source for stabilizing the output power of the sample of the pump light with respect to the predetermined reference output power level.

Abstract: The camera is equipped to reverse the direction of its moving focus lens (1) if appropriate focusing evaluation data is not obtained within a certain period of time after an intermediate point is detected during the focus lens movement in one direction. This eliminates the redundant operation of the focus lens moving away from the just-focus point all the way to the extreme of the current direction before heading back to the just-focus point during an auto focus operation. An efficient auto focus operation is thus achieved. In addition, control means (10) are provided for not using a decrease in accumulated data as auto focus control information if that decrease is judged to be an abrupt drop from the accumulated data obtained in the immediately preceding focus lens position. This makes it possible to prevent the focus lens (1) from being erroneously focused in cases of panning and other focus-disrupting operations. In this manner, the photographing of high quality is always made available.

Abstract: Hybrid document reproduction apparatus (10) (HYDRA) combining a printer, copier, scanner, and facsimile device and method of operation. This equipment includes, among other things, a mogation driven mechanical and electrical scanner (12) including an array of photodetectors (68) mounted on one side of a mogation bar (52) and an array of light emitting devices (70) mounted on the other side thereof. By mechanically mogating and driving the mogation bar (52) in a direction (72, 74) transverse to the movement of documents being copied (48) or printed (50) and by also simultaneously electrically scanning the photodetectors (68) and light emitting devices (70) on the mogation bar (52), the number of light sensitive and light generating devices required for a given printing or copying resolution are minimized. This feature in turn significantly reduces cost, weight, and heat dissipation requirements of this document reproduction apparatus and system while simultaneously optimizing its resolution capabilities and overall reliability. The above mogation operation may be achieved by mounting the ends of the mogation bar (52) into flexible disk members (64, 86) and then electromagnetically driving the mogation bar at the desired mogation frequency.

Abstract: According to a high efficiency coding signal processing apparatus of the present invention, in order to suppress error propagation, effectively correct errors, and reduce a signal deterioration upon repetitive coding processing, a bit rate reduction circuit (53) quantizes a video signal and outputs the resultant signal to low- and high-frequency encoders (71, 72, 75, 76). A first transmission sequence packet circuit (77) outputs low-frequency components at a predetermined period. A second transmission sequence packet circuit (79) sequences and outputs high-frequency components. Since the low-frequency components and the high-frequency components are separately sequenced and transmitted, the low-frequency components are free from the influence of errors caused in the high-frequency components.

Abstract: N-(2,2,6,6-tetraalkyl-4-piperidinyl)amine-hydrazides of dicarboxylic acids contain a light stabilizing group, a heat stabilizing group, a 5-membered lactam ring and a reactive hydrazide functionality in the same molecule. The reactive stabilizers can be prepared by reacting 4-amino-2,2,6,6-tetraalkylpiperidines with dialkyl itaconates followed by hydrazinolysis of the ester group of the intermediate mono ester-amide. The compounds are useful for introducing permanent heat and light stability to coreactive polymers or copolymers. They are also useful in the stabilization of inert polymeric systems against the degradative effects of heat and light when merely mixed with, rather than reacted with, the polymers for which stabilization is sought.

Abstract: For enhancing the efficiency of second harmonic conversion in a Type II phasematching material, the effects of wave vector double refraction are used to compensate for the effects of Poynting vector walk-off. To achieve this goal, the input fundamental beam (32) is arranged to enter the doubling crystal (30) at an oblique angle (ϑ) of incidence. This angle (ϑ) is selected so that the wave vector double refraction angle (δ) is equal to the Poynting vector walk-off (p). In order to maximize doubling efficiency, the axes of the crystal (30) must be oriented so that the optimum phasematching angle coincides with the propagation axis of the refracted fundamental beam travelling in the crystal. The crystal is preferably a KTP crystal used either for intracavity doubling (Fig. 5) or in an external resonant geometry (Fig. 6).

Abstract: To eliminate undesirable energy recorded during seismic surveying, a trace that models the undesirable energy on the recorded data trace is prepared. The model trace is first estimated using a suitable technique, such as wavefield extrapolation. Then, the model trace is modified using a best estimate of the amplitude, phase and time delay differences between the model trace and the data trace. The estimated amplitude, phase and time delay differences may be used to design a cross-equalization filter, which is used to cross-equalize the model trace with the data trace. Alternatively, the best estimate determination may include using a weighted sum of the model trace, its imaginary component, and their derivatives. When weighted and summed together, these components form a cross-equalized model trace that closely approximates the undesirable energy on the recorded data trace. Lastly, the cross-equalized model trace is subtracted from the data trace to substantially eliminate the undesirable energy.

Abstract: An apparatus for generating an atmosphere enriched with nitrogen in a container for storing perishable materials with the aid of a pressure-swing adsorption plant is to be improved in such a way that the enrichment with nitrogen is accomplished as rapidly as possible and that the changes in the desired composition can be carried out without major delay. Furthermore, the composition of the atmosphere in the container should otherwise remain substantially unaffected. To this end it is provided that the unit (1) has a compressor (5) and that the pressure-swing adsorption installation (3) is connected to the container (30) in a closed circuit in such a way that the container air is drawn off, is enriched with nitrogen and is returned to the container. The adsorber beds of the pressure-swing adsorption plant (3) are packed with a molecular sieve (9) suitable for adsorbing nitrogen. Owing to this manner of charging, the pressure-swing adsorption plant (3) is operated inversely to the conventional pressure-swing adsorption plants used for enrichment with oxygen. <IMAGE>

Abstract: A balanced driver circuit (28) essentially eliminates inductive noise without a power dissipation penalty, and is similar to a conventional balanced driver circuit except that the circuit is impedance matched at both ends and has resistors (44,46) connected in series with the outputs of the transistors (40,42) in the chip. The resistors are equal in value to a termination resistor (48,50) less the output impedance (R₀). of the transistors. The impedance between the pair of signal leads (32,34), referred to as the primary and secondary leads, is equal to the sum of the termination resistors (48,50). The current traversing the secondary lead has the same amplitude, but the opposite sign as the current traversing the primary lead. Thus, there is negligible current return through the common ground leads.
