Publication number: 20080039956Abstract: The invention relates to an arrangement of devices, such as, measuring devices or actuators, which are associated with process technology, and uni-directional or bidirectional data exchange with a central point, such as a control center or display device. A transmitting/receiving device is arranged such that data can be exchanged with the central point. The transmitting/receiving device is also arranged such that data from the other devices can be retrieved or transmitted further. The other devices do not comprise a transmitting or receiving device for direct communication with the central point.Type: ApplicationFiled: February 28, 2004Publication date: February 14, 2008Applicant: ABB RESEARCH LTD.Inventors: Raiko Milanovic, Rolf Merte, Armin Gasch, Fabrizio Lorito, Andrea Moroni, Franco Vecchiato, Corrado Bianchi, Eugenio Volonterio

Patent number: 7284437Abstract: The invention relates to a device and a method for the status monitoring of a pressure measuring unit in an absolute or differential or relative pressure transducer, a pressure-sensitive element installed in the pressure measuring unit being impinged with at least one pressure generated by at least one membrane. During a defined diagnosis time interval, a testing element integrated in the pressure measuring unit is induced to undergo a change in volume, preferably by electrical activation. The pressure difference caused as a result in the pressure measuring unit is registered by a pressure-sensitive element. The curve registered during a diagnosis time interval is compared with a reference curve recorded with the pressure measuring unit intact. A fault indication is given if the deviations between the registered curve and the reference curve exceed predetermined tolerance values.Type: GrantFiled: April 12, 2005Date of Patent: October 23, 2007Assignee: ABB Research LtdInventors: Peter Krippner, Wolfgang Scholz, Peter Riegler, Emrullah Altiok, Jürgen Biskup, Wilhelm Daake, Raiko Milanovic, Rolf Merte, Armin Gasch, Fabrizio Lorito, Andrea Moroni, Franco Vecchiato, Corrado Bianchi, Eugenio Volonterio

Patent number: 6999829Abstract: A technique to optimize both the production schedule and the maintenance of plant assets based on predetermined criteria which may be economic or otherwise. In one embodiment the technique receives at least one maintenance trigger (MT) and one production order and evaluates those inputs to propose one or more solutions for the joint scheduling of the asset maintenance and required plant production. In another embodiment a computerized maintenance management system (CMMS) acquires a new MT and proposes a new maintenance schedule. The technique transmits a blocking order to a production scheduling (PS) system for converting the maintenance request into a production schedule. In another embodiment, a CMMS acquires a new MT and asks for confirmation of a time slot to perform the maintenance action. The technique evaluates the priorities and finds based on the predetermined criteria the right time slot and communicates a request for that slot to the PS.Type: GrantFiled: December 26, 2001Date of Patent: February 14, 2006Assignees: ABB Inc., ABB Service S.r.l.Inventors: Renzo Bazzocchi, Fabrizio Lorito, Thoralf Schulz, Hartmut Wuttig

Patent number: 6437576Abstract: Method and device for the rapid detection of short-circuits in an electrical network. The method is based on estimating the electrical characteristics of the short-circuit load and calculating the peak value of the current on the basis of N successive samplings of the instantaneous current (i(t)). If the calculated value, typically available before the current actually attains this value, is greater than a pre-established threshold (Icc), a signal (C) is emitted indicative of a short-circuit fault. The calculation of the peak value may occur automatically for example upon switching on, or be subject to the exceeding of a guard threshold (Is) by the instantaneous current (i(t)). Moreover, the method makes it possible concurrently to determine the value of the power factor of the short-circuit (cos &phgr;) and the phase of the voltage at the moment of the short-circuit.Type: GrantFiled: June 5, 1998Date of Patent: August 20, 2002Assignee: ABB Research Ltd.Inventor: Fabrizio Lorito

Patent number: 5905615Abstract: An electric power distribution system having a number of automatic protection breakers distributed on various levels is disclosed herein. Each protection breaker includes an electronic protection unit to open the breaker, which is controlled based on the amount of current flowing through the breaker and its derivative. Each of the breakers is preferably connected in order to exchange information concerning their respective status. Also disclosed herein is method for controlling the intervention sequence of the mutually interlocked breakers, in which a breaker reports a detected fault condition to its next higher level breaker.Type: GrantFiled: October 23, 1997Date of Patent: May 18, 1999Assignee: ABB Research Ltd.Inventors: Giandomenico Rivetti, Fabrizio Lorito, Serverino Colombo, Jan Teigland, Rolf Disselnkotter, Erik Carlson
