Abstract: A method and system for providing a customer with a service upon a service request. The method includes retrieving a dataset from a database for identifying a qualified service person using information about the service, the service person and a customer; establishing communication with the customer; and providing the customer with the service. After the service is performed, the retrieved dataset is updated to maintain accurate information stored in the database.

Abstract: The aim of the invention is to be able to adapt an item of visualization or optimization software with the least possible amount of effort made on any electrostatic filter configurations. To this end, the invention provides that the electrostatic filter, the high-voltage supply units, and the auxiliary functional units can be used by the software modules in the server component as objects with characteristic features and with characteristic methods, that are capable of being accessed as information, which only exists in the server component, for the client modules via data interfaces.

Abstract: A PC-arrangement is for visualisation, diagnosis and expert systems for monitoring, controlling or regulating high voltage supply units of electric filters. The PC-arrangement for visualisation, diagnosis and expert systems for monitoring, controlling and regulating high voltage supply units of electric filters includes a server-PC which is linked to high-voltage supply units of electric filters via a first network; and a client-PC forming a second network with the server-PC. In order to keep the network load on the first network connecting the server PC to the high voltage supply units as low as possible and to use Microsoft-standard mechanisms for distributed systems in order to achieve network capability for visualisation and measuring data processing systems, a software structure of the PC-device is broken down into autarchic software modules which respectively carry out at least one function.

Abstract: Disclosed is a high-voltage supply unit for electofilters. The unit includes high-voltage devices which are arranged close to the electrofilter and by which the electrofilter is supplied with high voltage, measuring heads which are assigned to the high-voltage devices and by which measured values and optional diagnostic data from the high-voltage devices are detected and transmitted, and control units, each of which is assigned to one high-voltage device and by which the high-voltage devices assigned thereto are controlled and regulated according to the requirements and by taking into account measured values and optional diagnostic data that are transmitted by the measuring heads.

Abstract: The present invention provides an efficient and simple method and system for providing a customer with a service on demand. The invention is based on providing a plurality of interconnected technical devices with remote access. During operation of a technical installation including the technical devices, operating data are acquired, encrypted and stored in a operation database. Upon an explicit service request by the customer, at least one of the technical devices sets up a remote connection to a service center, preferably by using a smart card including Public Key Infrastructure (PKI) data for validating the smart card, where the remote connection is verified and the encrypted data stored in the operation database are read out and decrypted. Based on the decrypted data—which represent a current status of the technical installation—, a service activity is efficiently performed at the technical installation, either remotely or locally.

Abstract: The present invention provides an efficient and simple method of monitoring a facility including entertainment functionality, wherein a first data set relevant to operational purposes of the facility is acquired and a second data set relevant to entertainment purposes is inputted. After selecting either the first or the second data set, the selected data set is processed and output. The processed data set is preferably transmitted to an output device over an at least two-channel transmission device, wherein the first and the second data set are assigned separate channels.

Abstract: A method is for operating an electrostatic filter. The real electrostatic filter is transformed to a filter model that includes at least one inlet zone, at least one center zone and at least one outlet zone. A predetermined characteristic is associated with every of the three model zones. The energy supply for a predetermined number of the model zones is controlled in accordance with the characteristic and depending on the desired value of particle emission.

Abstract: A filter short circuit is detected when the primary voltage of the high-voltage transformer drops below a specified minimum value and does not rise above the specified minimum value during a specified delay period and a filter current is greater than a specified minimum current. No current is drawn from the external current supply for a variable time delay when a filter short circuit is detected. A filter short circuit count is incremented when a filter short circuit is detected. When the count exceeds a specified, variable limit within a specified, variable time span, the indirect converter is disconnected.
