Title: Method for anisotropic etching of structures in conducting materials
Inventor: OLSSON LENNART
IPC: C25D7/12
Filed: 1997-09-05
Abstract: In a method for anisotropic etching of a structure in an electrically conductive substance to be etched, use is made of an etchant which in concentrated solution is usable for isotropic etching of structures in the substance to be etched. The substance to be etched is contacted with the etchant in a solution which is so diluted that the etchant is unusable for isotropic etching. The etchant is subjected, adjacent to the substance to be etched, to an electric field of such a strength that anisotropic etching of the substance to be etched is accomplished. Moreover, an etching fluid is described, comprising an etchant in dilute solution, in which the etchant is present in a concentration of 200 mM at most, and use of such an etching fluid for making structures which are 50 µm or less is also described.
Patent CA-2266679-A1 (CA)
Title: Satellite attitude sensor using thermal imaging
Inventor: THOMAS PAUL J
IPC: B64G1/36
Filed: 1997-09-17
Abstract: The present invention provides a method for distinguishing a boundary of an object, and the object itself, from its background. In the method electromagnetic radiation is detected from at least two fields of view substantially spanning the boundary of the object and background adjacent to the boundary and superimposed or overlaid as images onto a detector (36). The method includes correlating spatial transitions in intensity of the overlaid images on the detector with a boundary of the object.      When used for determining the attitude of a satellite with respect to the earth, the detector is a thermal infrared detector (36) thereby providing a sharp contrast between the thermal emission of the earth and cold space. The invention provides a simple, effective method and device for determining satellite orientation and/or attitude with respect to a thermal infrared-emitting target body.      The sensor includes a segmented limb-looking mirror (32) to provide multiple fields-of-view within the field-of-regard and superimposing these fields-of-view as images onto a common detector (36).  The required resolution can be obtained while providing a wide range of operational orbital altitudes. The attitude of the satellite can vary by a large angle from the minimal orientation while still permitting an accurate determination of attitude. Multiple channels in a modular form provide redundancy, improved accuracy, and the opportunity of providing more diverse configurations. The utilization of uncooled microbolometer arrays as imaging detectors removes the requirement for additional cooling equipment thereby providing a low cost, small size and low mass sensor with configurational flexibility and no moving parts.

Filed: 1997-06-04
Abstract: An electrosurgical blade (100) is provided having a ceramic (104) coating which is conductive, flexible and provides a surface which inhibits the build up of charred tissue. These properties enable the electrosurgical blade to deliver controlled amounts of radio-frequency energy to tissue. The manufacturing process produces a coating of titanium nitride on a stainless steel blade which is amorphous, enabling the electrosurgical blade to bend with the blade in order to perform a wide variety of surgical procedures without damaging the coating. The electrosurgical blade can therefore be used to efficiently cut, coagulate, fulgurate and desiccate tissue. While the blade is primarily used in the monopolar mode, the present invention also encompasses at least two electrosurgical electrodes having the same ceramic coating as the electrosurgical blade, and used in the bipolar mode for coagulation.
