Abstract: Optics (20) for an illumination device (1), as well as an illumination device (1) comprising such optics. The optics comprise at least one lens (30) with a light entry surface (31) and a light exit surface (32). A stepped lens structure (321), such as a Fresnel structure, is formed on the light exit surface. A recurring surface structure, such as periodically arranged prominences (311) and deepenings (321), are formed on the light entry surface (31).

Abstract: The disclosure provides a supplemental device configured for removable attachment to a medicament injection device. The supplemental device includes a display, a processor arrangement, at least one memory, and an image-capturing component. The processor arrangement is configured to cause the supplemental device to: (i) use the image capturing component to capture successive images of a medicament dosage indicated by a medicament dispensing device, (ii) successively display the captured images on the display, (iii) perform optical character recognition on captured images to identify medicament dosage indicated by the medicament dispensing device when the images were captured, (iv) and make a non-transient record of delivered dosage information in the at least one memory based at least in part on the identified medicament dosage.

Abstract: A power plant including an apparatus for regasification of liquefied natural gas (LNG) is provided. The apparatus includes a compressor configured to pressurize a working fluid and a heat recovery system configured to provide heat to a working fluid. A turbine is configured to generate work utilizing the heated working fluid. One or more heat exchangers are configured to transfer heat from the working fluid to a first stage liquefied natural gas at a first pressure and at least one of a second stage liquefied natural gas at a second pressure, and a compressed working fluid.

Abstract: A heat exchanger comprises a tube and fins extending from an outer surface of the tube. The fins comprise first and second sets of fins with the first set of fins oriented in a first direction with respect to an axial direction of the tube and the second set of fins oriented in a second direction with respect to the axial direction of the tube to expose at least a portion of the first and second sets of fins to a free stream.

Abstract: A self-piercing rivet of a special rivet geometry is described, which in particular is suitable for joining high strength steel sheets, but can also be used for other metal sheets. The self-piercing rivet is in particular characterized by a special underhead geometry as well as a special geometry of the rivet foot (cutting region). Thus the self-piercing rivet has an underhead chamfer which with a radial plane of the self-piercing rivet encloses an angle of 20°+5°/?5° and merges tangentially into the cylindrical outer surface of the rivet shank via a radius. In the region of the rivet foot the self-piercing rivet has a plane shank face, which extends essentially at a right angle to the rivet axis and which merges “smoothly” into the cylindrical inner surface via a shank inner surface and a radius.
