  • Patent number: 11652738
    Abstract: A device may provide path data identifying a primary path and one or more alternate paths for segment routing traffic in the network, and may receive performance data indicating a performance degradation in the primary path. The device may determine that the performance data satisfies a first threshold, and may request, based on the performance data satisfying the first threshold, alternate path performance data. The device may receive the alternate path performance data based on the request, and may compare the alternate path performance data for the one or more alternate paths. The device may select a particular alternate path, of the one or more alternate paths, based on comparing the alternate path performance data for the one or more alternate paths, and may trigger, based on the performance data satisfying a second threshold, a failover of the traffic from the primary path and to the particular alternate path.

  • Patent number: 9088801
    Abstract: The invention pertains to a method for operating an image-processing device, in which an image signal is digitally transmitted between a transmitter and at least one receiver, and in which the image signal comprises a timed sequence of images. An alternating signal which alternates at a signal alternation frequency is superimposed on the image content of the images before they are transmitted, and the signal alternation frequency is greater than or equal to the perception frequency resolvable by the human eye. The invention also pertains to an image-processing device.

  • Publication number: 20120317958
    Abstract: In a method of operating a motor vehicle, a temperature is measured of a charge-air flow in flow direction of the charge air downstream of a compressor impeller of each of two turbochargers, and a difference between the temperature of the charge air downstream of the compressor impeller of one of the turbochargers and the temperature of the charge air downstream of the compressor impeller of the other one of the turbochargers is determined. The presence of a difference in the temperatures for the turbochargers is an indication that one of the turbochargers operates at a higher rotational speed so as to allow initiation of preventive measures in order to avoid damage as a result of excessive rotational speed.

  • Patent number: 7796113
    Abstract: The aim of the invention is to largely prevent certain influences from distributing the luminance of an image that can be reproduced on a panel of a flat screen. To this end, light-permeable parts are arranged between a sensor and a back light illuminating the panel from the rear, the ageing and/or temperature properties of said light-permeable parts essentially corresponding to those of the light-permeable parts of the panel.

  • Publication number: 20070127045
    Abstract: In one aspect an arrangement for data transmission between an image source and an image reproducing system is build, with digital R/G/B video signals being able to be fed to the image reproducing system via an R/G/B path pair in each instance and a communication signal. Measures are proposed which reduce the transmission time required to transmit large data volumes in a communication operating mode.

  • Patent number: 6302083
    Abstract: The values for the speed of the crankshaft are corrected by means of an acausal mean-value filter, and the change in the kinetic energy of the crankshaft in the expansion interval of a cylinder is calculated from the dynamically corrected speed values and referred to the maximum fuel quantity which can be fed in this interval. The dimensionless residue obtained therefrom represents for the cylinder under consideration a measure of too much or too little injected fuel. Correction terms are derived from the calculated residues for the injection times of the individual cylinders. This renders adaptation possible in the overall region of the characteristic diagram, in particular also in the case of speed transitions.
