Abstract: This disclosure describes a circuit implementation providing the functions necessary to implement an isolated I2C bidirectional port. The technique implements a current source as a pull up device on at least one side of the isolation system. The circuit manages and communicates bidirectional data across an isolation barrier. A method of communicating bidirectional signals and an I2C acknowledge (ACK) or clock stretching through an isolation channel is disclosed.

Abstract: The invention is directed to coating compositions comprising A) at least one hydroxyl-functional and optionally acid-functional binder, preferably with an acid number of 0 to 150 mg KOH/g binder solids, B) at least one polyisocyanate curing agent with free isocyanate groups, C) at least one thermally latent tetrahydrocarbyl tin catalyst of general formula (I) RnR?4-nSn??(I) wherein R is an alkyl group, R? is an aryl, arylalkyl or alkenyl group and n is 1, 2 or 3, and D) optionally at least one acid-functional compound, that is different from component A), with the proviso that the acid number of a composition, consisting of the at least one binder A) and optionally of the at least one acid-functional compound D), has an acid number of at least 5 mg KOH/g solids, preferably of least 10 mg KOH/g solids, and to a process for coating substrates comprising the steps: I) applying the coating composition to an optionally pre-coated substrate, and II) curing the applied coating composition by means of thermal

Abstract: The present invention is directed to a process of applying a solvent-based coating composition on a substrate to produce a multi-layer coating thereon. The binder component of the composition includes at least one hydroxy-functional polyether obtained from at least one polyol having at least three hydroxyl groups and at least one monoglycidyl ester of a branched monocarboxylic acid. The crosslinking component of the composition includes at least one cross-linking agent that is capable of entering into a cross-linking reaction with the hydroxyl groups of- the hydroxy-functional polyether. The process further includes curing the multi-layer coating. The process is well suited for producing clear coats and pigmented topcoats in automotive refinishing.

Abstract: A device (100) for generating a vibration source driving signal (DS) is described, which device (100) comprises an input (101) for receiving an input signal (IS) and an output (102) for providing said driving signal (DS), generating means (103; 803) for generating a control signal (CS) which is representative of dynamic signal changes of the input signal (IS), and a processing unit (105; 201; 301; 401; 804) adapted to process a source signal (SRS; IAS) based on the control signal (CS) yielding said driving signal (DS).

Abstract: The present invention relates to a method for optimizing the supply of a catalyst slurry during a polymerization process for preparing a polyolefin in a polymerization reactor (1), whereby said slurry consists of solid catalyst particles suspended in a hydrocarbon diluent and is characterised by a ratio of solid catalyst particles/diluent, whereby the catalyst slurry is fed to the reactor through at least two parallel catalyst feeding conduits (4, 104) which are intermittently operative in the polymerisation process, said method comprising the steps of: determining an effective initial ratio solid catalyst particles/diluent for the polymerization process; determining the actual ratio solid catalyst particles/diluent in a first operative feeding conduit (4); calculating the difference between actual and initial ratio and in the event that said difference is more than a specified threshold, shutting down the first catalyst feeding conduit (4) and activating a second catalyst feeding conduit (104).
