Patent CA-2297177-A1 (CA)
Inventor: WITTE FRANZ
IPC: G01S13/933
Filed: 1998-07-21
Abstract: The invention pertains to an on-board radar equipment as part of the avionic system in an aircraft, said equipment providing a two-dimensional representation of the radar data from an area located upstream relative to the flight direction. The inventive radar equipment is an upstream sighting radar which gives of the radar data a high resolution and map-consistent representation from above in accordance with its basic operating mode resting upon the SAR(synthetic aperture radar)-based processing principle or an equivalent principle. A digital image processor enables a purely geometrical conversion of the map-consistent representation from above provided by said radar equipement into a corresponding image with a centered perspective projection and with a quasi-pilot vision. The invention is used when aircrafts and helicopters fly under bad visibility conditions or with no visibility at all.

IPC: C23C16/448
Filed: 1997-10-06
Abstract: A method for dissociating metal-ligand complexes in a supercritical fluid by treating the metal-ligand complex with heat and/or reducing or oxidizing agents. Once the metal-ligand complex is dissociated, the resulting metal and/or metal oxide form fine particles of substantially uniform size. In preferred embodiments, the solvent is supercritical carbon dioxide and the ligand is a .beta.-diketone such as hexafluoroacetylacetone or dibutyldiacetate. In other preferred embodiments, the metals in the metal-ligand complex are copper, silver, gold, tungsten, titanium, tantalum, tin, or mixtures thereof. In preferred embodiments, the reducing agent is hydrogen.  The method provides an efficient process for dissociating metal-ligand complexes and produces easily-collected metal particles free from hydrocarbon solvent impurities. The ligand and the supercritical fluid can be regenerated to provide an economic, efficient process.

Patent CA-2326224-A1 (CA)
Inventor: BLIXT PETER
IPC: H01S3/06
Filed: 1999-04-01
Abstract: An optical fiber amplifier for WDM-signals comprises an active optical fiber (1, 3) pumped with pumping light from a pump source (17). In order to give the amplifier a constant gain for the WDM-signals irrespectively of the number of active WDM-signals an additional light source (29) is arranged to inject, when required, extra light into the active optical fiber, at least in a portion (3) thereof, through a power combiner (27). The injected light has a wavelength different from that of the WDM-channels and preferably longer so that it will not cause an amplifying or pumping effect in the active optical fiber but so that it still can be amplified in the active fiber. The light source (29) is controlled by a signal derived from an output power measurement device (23) so that it will inject extra light when a WDM-channel becomes inactive. The power of the extra light is thus selected to saturate the optical fiber amplifier at a constant gain irrespectively of the number of signal channels, i.e. of the total power of the input light signals. A light filter (18) can be connected to the output end of the active optical fiber (1, 3) to block light having a wavelength corresponding to the wavelength of the light issued from the light source (29). Controlling the gain by this injection of "extra signal light" is much quicker than controlling the power of the pumping light.

Title: Self referencing mark independent alignment sensor
Inventor: KREUZER JUSTIN L
IPC: G01B11/00
Filed: 2001-02-27
Abstract: Coherent illumination (12) is used to illuminate a symmetrical alignment mark (18) with an image rotation interferometer (26) producing two images of the alignment mark, rotating the images 180° with respect to each other, and recombining the images interferometrically. The recombined images interfere constructively or destructively, in an amplitude and or polarization sense depending upon the method of recombination, when the alignment sensor (10) is located at the center of the alignment mark. The rotation interferometer (26) is preferably a solid glass assembly made of a plurality of prisms. A detector (28) extracts the alignment information from the image rotation interferometer (26). The resulting center of the alignment mark (18) is accurately determined. A relatively large number of different alignment mark patterns may be utilized, as long as the alignment mark patterns exhibit one hundred and eighty degree symmetry. Parallel lines, a grid pattern, or a checkerboard grating may be used. The alignment sensor (10) may be applied to a scanning photolithographic system providing sinusoidal alignment signals. The alignment system is particularly applicable to photolithography as used in semiconductor manufacturing.
