Patent CA-2318080-A1 (CA)
Title: Wavelength-selective optical add/drop using tilting micro-mirrors
Inventor: TOMLINSON W JOHN
IPC: G02B6/34
Filed: 1999-01-27
Abstract: An optical switch particularly usable as a wavelength-division add/drop multiplexer (WADM) in a multi-wavelength communication system. Four multi-wavelength beams optically coupled to the input, output, add, and drop channels are arranged in parallel in a rectangular array and are incident upon a diffraction grating. The grating operating in one direction disperses the beams into their wavelength components and operating in the other direction recombines the wavelength components into a multi-wavelength beam. A lens focuses the components of the beams having a particular wavelength upon one of an array of tiltable micro-mirrors integrated on a silicon substrate. In one position, the mirror for a particular wavelength reflects that wavelength component from the input beam back to the output beam. In a second position, that mirror reflects that wavelength component from the input beam back to the drop beam and reflects that same wavelength component from the add beam back to the output beam. The same optics can be used for a second set of beams which are switched in synchronism with the first set. The array of mirrors can be fabricated to be tiltable to more than two positions so that the input beam can be selectively coupled to either the output beam or one of at least two drop beams while the ouput beam is correspondingly selectively coupled to either the input beam or one of at least two add beams.

Filed: 1999-03-26
Abstract: This invention provides for new recombinant ribonuclease proteins which are active when expressed by bacteria. This allows the recombinant ribonucleases of this invention to be fused in-frame with ligand binding moieties to form cytotoxic fusion proteins. Furthermore, these proteins are more active than ribonucleases currently available even though the proteins of this invention lack an N-terminal pyroglutamic acid, which has been found to be necessary for ribonucleolytic activity. Because these proteins are recombinant proteins, mutations which increase cytotoxicity can be engineered.

Title: Fault type selection system for identifying faults in an electric power system
Inventor: ROBERTS JEFFREY B
IPC: H02H3/28
Filed: 2001-10-19
Abstract: The fault identification system includes a first logic circuit which is responsive to conventional protective elements which recognize the presence of low resistance single line-to-ground faults for the A, B and C phases on a power transmission line. The first logic circuit includes a portion thereof for recognizing and providing an output indication of single line-to-ground faults, faults involving two phases and three-phase faults, in response to the occurrence of different combinations of outputs from the protective elements. A calculation circuit, when enabled, is used to determine the angular difference between the total zero sequence current and the total negative sequence current for high resistance faults when the protective elements themselves cannot identify fault conditions. The angular difference is in one of three pre-selected angular sectors. An angular difference in the first sector indicates an A phase-to-ground fault or a BC phase-to-phase to ground fault; an angular difference in the second sector indicates a B phase-to-ground fault or a C phase-to-phase to ground fault; and a signal in the third sector indicates a C phase-to-ground fault or an AB phase-to-phase to ground fault. A processor is used to determine which of the two possible for each angle determination is the actual fault type. An output indication of the actual fault type is then provided.
