Title: Method for detecting objects with visible light
Inventor: CANTIN DANIEL
IPC: G01S17/06
Filed: 2008-06-18
Granted: 2015-11-24
Abstract: A method for detecting an object using visible light comprises providing a visible-light source having a function of illuminating an environment. The visible-light source is driven to emit visible light in a predetermined mode, with visible light in the predetermined mode being emitted such that the light source maintains said function of illuminating an environment. A reflection/backscatter of the emitted visible light is received from an object. The reflection/backscatter is filtered over a selected wavelength range as a function of a desired range of detection from the light source to obtain a light input. The presence or position of the object is identified with the desired range of detection as a function of the light input and of the predetermined mode.

Abstract: An in-situ method for regenerating a deactivated catalyst removes a calcium sulfate layer masking active catalyst sites. A reducing agent converts the calcium sulfate to calcium oxide, which is then removed, by reintrainment into the flue gas steam using soot blowers or sonic horns. The method is particularly useful for regenerating selective catalytic reduction (SCR) catalysts used to remove nitrogen oxides from flue gas produced by combustion of coal from the Powder River Basin. The method can be practiced using existing SCR system hardware, and without removing the SCR system from service.

Abstract: A soil and/or moisture resistant secure document and a method for producing such a secure document, are provided. The inventive method preferably employs a size press or other similar device to force a soil and/or moisture resistant formulation into the pores of the substrate and to remove excess formulation from opposing surfaces thereof. Soil and/or moisture resistant formulations when applied this way instead of by way of standard coating techniques do not obscure optically variable effects generated by non-porous OVDs that may be employed on or within these secure documents. In addition, thin layers of fibers (e.g., papermaking fibers) overlying and thus embedding portions of security devices in windowed secure documents that have been rendered soil and/or moisture resistant in accordance with this invention demonstrate increased durability.
