Title: Dynamic optical amplifier
Inventor: BALL GARY A
IPC: H04B10/17
Filed: 1998-06-25
Abstract: An optical amplifier for amplifying a plurality of signal components of a mult-wavelength optical beam passing through an optical fiber includes a portion of the optical fiber doped with a rare earth ion to amplify the optical signal wherein the gain spectrum as a function of the wavelength is nonuniform. The optical amplifier further includes a gain flattening module to compensate for the nonuniform gain spectrum of the doped fiber by attenuating each of the channels of the amplified signal to equalize the gain. A gain equalization module compensates for varying gain fluctuations due to the adding and subtracting of signal components. The gain equalization module adjusts dynamically each signal component of the optical beam such that the amplitudes of the signal components are substantially equal, in response to a plurality of control signals. Each control signal is representative of the degree of attenuation required to equalize the signal components. The respective control signals are generated by a loop status monitor that includes a waveguide for demultiplexing the optical beam, and a detector array that determines the amplitude of each signal component. A controller generates the control signals in dependence of the amplitude of the signal components.

Inventor: PATEL NAGAR J
IPC: H01H11/00
Filed: 2000-03-09
Abstract: Operation of a medium voltage spring powered circuit breaker is analyzed by determining the linear position of a selected driven part of the circuit breaker operating mechanism. When the charged closing springs of the operating mechanism are released, the selected driven part, such as a vacuum interrupter stem or push rod, moves to a new linear position as actuated by the release of the charged closing springs. Linkages are provided to the driven parts. LVDT sensors engage each of the linkages to determine the linear positions of the driven parts. A processing unit collects operation data for the operating mechanism when the charged closing springs are released to actuate and produce linear movement of the driven parts. The operation data includes a plurality of the linear positions of the driven parts. A microprocessor-based routine and interface outputs the operation data.

IPC: H04L12/56
Filed: 2000-06-02
Abstract: An apparatus and method of forwarding a first message from a source to a destination via a link state routing network utilizes point-to-point feedback messages when the quality of a first path from the source to the destination meets some prescribed condition. To that end, the first path is initialized within the link state routing network. A feedback messag e having data relating to a quality of the first path then is received as a point-to-point message that is forwarded to the source. In response to receipt of the feedback message, a second path is initialized from the source to the destination. The first message then is forwarded to the destination via the second path.
Patent CA-2310604-A1 (CA)
Inventor: HONG JIN
IPC: H01S5/343
Filed: 1999-11-10
Abstract: A gain coupled DFB semiconductor laser with a high order grating structure is provided. By varying the order and duty cycle of the grating and shape of grooves, a predetermined ratio of gain to index coupling coefficients is obtained. Beneficially the laser includes a multiple quantum well structure with the grating etched directly through the quantum wells of the active region. Deep etching ensures strong gain coupling in the laser while usage of a high order grating reduces index coupling associated with the etching. As a result, a stable, high yield, high power and single mode operation of the DFB laser is achieved. For gratings of a particular order of diffraction, duty cycle, shape of grooves and depth of etching index coupling may be substantially reduced or eliminated. Correspondingly, a purely gain coupled DFB laser may be obtained. It is also easier to manufacture high order DFB lasers because of the larger period of gratings allowing larger fabrication tolerances. A method of producing a complex coupled DFB semiconductor laser having a predetermined ratio of gain to index coupling, and a method of obtaining a purely gain/loss coupled semiconductor DFB laser are also provided.

Title: Reduced malto-oligosaccharides
Inventor: BARRESI FRANK W
IPC: C08B30/18
Filed: 1999-01-19
Abstract: Disclosed are a method for the reduction of an oligosaccharide mixture and an oligosaccharide mixture prepared thereby. In accordance with the disclosed invention, a mixture of oligosaccharides having a given DP  profile is reduced to a DE of essentially zero by catalytically hydrogenating the mixture under reaction conditions sufficient to preserve the DP profile of the mixture, which reaction conditions typically include a reaction temperature ranging from about 50 °C to about 150 °C and a reaction pressure ranging up to about 1500 psi. Surprisingly, when the mixture is a malto-oligosaccharide mixture, the reduced mixture will have a superior color-fastness and thermal stability as compared to a similar unreduced mixture of malto-oligosaccharides, and also low reactivity towards nitrogen-containing species.
