Abstract: A system and a method for detecting a maintenance problem in a vehicle are disclosed. The method comprising: receiving a temporal EM emission field at a plurality of locations inside the vehicle, when the vehicle is in use; receiving from database information related to a typical temporal EM emission field at the plurality of locations inside a reference vehicle; determining a deviation from the typical temporal EM emission field, and detecting a maintenance problem in the vehicle if the deviation is above a threshold value.

Abstract: A method of reducing electromagnetic (EM) radiation inside a vehicle, is disclosed. The method comprises: determining, for at least one location inside the vehicle an existence of at least a first EM radiation vector, and emitting, from at least one emitting element, EM radiation characterized by producing, in the at least one location, at least a second EM vector having an opposite direction to the at least first EM radiation vector.

Abstract: A metasurface lens assembly to perform chromatic separation includes a first layer with a plurality of nanofins extending transversely there from and each being optically anisotropic and transmissive to light in the visible spectrum and having an optical characteristic that is set according to a phase profile. A second layer is spaced apart from the first layer and includes a plurality of photosensitive subpixels each associated with a different color. In operation, many beams of light may be directed onto the metasurface lens from a source with each beam of light having a plurality of component colors. The nanofins may function in combination with one another according to the phase profile to bend and focus the beams of light onto the second layer with each of the component colors being bent and focused differently to direct the component colors onto corresponding ones of the photosensitive subpixels.

Abstract: An apparatus for adapting a data structure between a numerical controller and a machine includes a data acquisition logic unit connected to the machine for acquiring values of machine parameters characteristic of a machine state. The data acquisition logic unit includes an interface module containing rules which are used to transform a machine data structure of the values of machine parameters into a control data structure which can be read by the numerical controller. In a corresponding method, values of the machine parameters which occur in a first machine state are transmitted to the data acquisition logic unit and stored therein. The machine state is assigned to the stored values of the machine parameters as at least one rule for interpreting the values of the machine parameters.

Abstract: In a method for issuing an access authorization for a software product provided on an application server, provision is made for a license server to establish, electronically sign and transfer a license token to the application client, which transmits the license token to the application server. Since the application client supplies its access authorization for access to the software product with the request for the software product, a rapid and efficient checking of the access authorization is possible, even without a connection between the license server and the application server during the request.

Abstract: Provided herein are methods of administering a 5,5-fused heteroarylene hepatitis C virus inhibitor compound or an isotopic variant thereof, or a pharmaceutically acceptable salt or solvate thereof; for treating or preventing hepatitis C virus infection in a subject.

Abstract: A process is provided for the preparation of a key intermediate in the preparation of 2?-branched nucleoside compounds. The process includes contacting a protected precursor 3,4-O-isopropylidene-2-C-substituted-D-arabinono-1,5-lactone with a fluorinating agent under anhydrous conditions and converting the precursor into a protected 2-deoxy-2-halo-2-C-disubstituted ribono-1,5-lactone and optionally into a 2-deoxy-2-halo-2-C-disubstituted ribono-1,4-lactone.
