20100290336 | Optimized Bandwidth Allocation for Guaranteed Bandwidth Services - A method for minimizing bandwidth allocation for alternative routes within a network provides a management system for managing routes of services, provides a plurality of guaranteed bandwidth (GWB) services, assigns to each GBW-service a traffic class (TC), and calculates for each GBW-service of a protected TC an active route and an alternative route. The active route is a planned route in case of absence of a respective network failure and the alternative route is the route which guarantees that, in case of a network failure with respect to the active route, the GBW-service is protected. Further, a first optimized protection mode is provided to be assigned to all the GBW-services belonging to a given protected TC. The first optimized protection mode has a first optimization step including reserving bandwidth for each GBW-service only once for each network resource employed by the active and/or the alternative route of each GBW-service. | 11-18-2010 |

20120167656 | Method and Diagnostic Device for Diagnosing a Heatable Exhaust Gas Sensor of an Internal Combustion Engine - A method is described for diagnosing a heatable exhaust gas sensor of an internal combustion engine, in which a predefined chronologically varying or constant voltage or a predefined chronologically varying or constant current is generated with the aid of a voltage source, the voltage or the current is applied to terminals of the exhaust gas sensor, a current or applied voltage, which flows through the voltage source when the voltage or the current is applied, is detected, and the current or the voltage is analyzed to diagnose the exhaust gas sensor. To diagnose the exhaust gas sensor, which permits a reliable and accurate diagnosis of the exhaust gas sensor and allows a statement about the type of a possibly existing error on the exhaust gas sensor, the method is executed independently of a control and/or regulating unit of the internal combustion engine, an operating temperature of the exhaust gas sensor being regulated to a predefined temperature value with the aid of a regulating element, which is separate from the control and/or regulating unit. | 07-05-2012 |
