Abstract: There is provided an optical frequency converter comprising: an optical guiding structure having an input and an output, and comprising: a first grating portion adjacent to the input; a second grating portion adjacent to output, and a third grating between the first and second grating portion to form an apodized step-chirped grating extending between the input and the output. Each grating portion comprises a plurality of sections each comprising a plurality of segments. Each segment has a segment width and comprises a poled region having a poled width at least equal to one micron and a reversely poled region. The segment width for all of the grating portions and a duty ratio of the poled width to the segment width are constant within each section. The duty ratio increases within the first grating portion, decreases within the second grating portion, and is constant within the third grating portion.

Abstract: A bicycle power meter has a strain gauge sensor assembly mounted on a relatively compressible portion of the end of the rear fork of the bicycle frame. The relatively compressible portion is near the rear hub and subject to the forces exerted by the cyclist to the crankset, and transferred via the chain, and sprocket assembly to the hub. The sensor assembly has two ohmically interconnected stretch sensors each having a first layer bearing a variable resistance element, whose resistance changes with displacement of the compressible portion, and a second layer for providing support for the first layer. The sensor assembly is connected in a bridge circuit to two other resistances to generate signals representative of cyclist applied force. These signals are processed along with velocity signals to generate power signals and the power signals are supplied to a display.

Abstract: The invention pertains to a method for preparing a composite printing form from a single precursor that is capable of forming a relief and a carrier. The single precursor can be a single photosensitive element or a single laser-engravable print element having a reinforced elastomeric layer. The single precursor has a size that is at least 70% of a size of the carrier. The single precursor is located on the carrier by approximately positioning the precursor on the carrier that has no registration markings. Precise registration of the single precursor is achieved by using digital information generated from a computer to create the registered image on the composite form. The method is particularly suited for preparing composite printing forms for relief printing, and in particular for preparing composite printing forms for flexographic printing of corrugated substrates.
Abstract: The invention provides an ink for inkjet printing, comprising a self-dispersing pigment colorant and certain urea terminated polyurethanes derived from alpha-omega diols and/or polyetherdiols which enhances print quality especially gloss and distinctness of image without compromising jetting performance.
