Method for detecting inadmissible operating conditions of work hydraulics of an agricultural tractor
Patent number: 11589493Abstract: A method is provided for detecting inadmissible operating states of a work hydraulics of an agricultural tractor. The method includes providing at least one electrically actuated control valve, a branch allocated to the at least one control valve, and an operating unit for the manual actuation of the work hydraulics of a front linkage. The method also includes connecting the at least one electrically actuated control valve to a hydraulic consumer via a hydraulic coupling, supplying hydraulic fluid to a hydraulic lifting device of the front linkage, detecting a state variable indicative of a connection state of the hydraulic coupling by a sensor unit and communicated to a control unit, and deactivating the operating unit if the control unit identifies by way of the evaluation of the state variable that a hydraulic consumer is connected to the hydraulic coupling.Type: GrantFiled: August 5, 2020Date of Patent: February 28, 2023Assignee: DEERE & COMPANYInventors: Felix P.

Patent number: 10077718Abstract: A method for operating a gas turbine plant having a gas turbine and an electric generator driven by the gas turbine. The method includes detecting an instantaneous power of the gas turbine plant; comparing the detected instantaneous power with a power limit value; and limiting the instantaneous power when the result of the comparison is that the detected instantaneous power is equal to or greater than the power limit value. A step of detecting at least one operating parameter of the gas turbine plant and a step of determining the power limit value as a function of the at least one detected operating parameter are then implemented, wherein the at least one operating parameter of the gas turbine plant includes an ambient pressure and the power limit value is increased when the ambient pressure increases.Type: GrantFiled: March 3, 2015Date of Patent: September 18, 2018Assignee: Siemens AktiengesellschaftInventors: Jan-Dirk Beiler, Hans-Georg Gamm, Thomas Kerstiens, Marco Larson, Rosa-Eos Mühlhölzer, Florian Purps, Oliver Schneider, Marc Schäfer, Philipp Kreutzer, Marc Reinberg, Martin Stapper

Publication number: 20140345290Abstract: A method for stabilising a network frequency with a gas turbine that can be operated using syngas and an additional fuel is provided. The mass-flow of the additional fuel, supplied to operate the gas turbine, can be increased more quickly than that of the syngas and, in order to stabilise a network frequency, a ratio of the mass-flow of syngas to that of the additional fuel, for operating said gas turbine, is modified by the mass-flow of said additional fuel being modified while the mass-flow of the syngas remains the same.Type: ApplicationFiled: November 15, 2012Publication date: November 27, 2014Applicant: Siemens AktiengesellschaftInventors: Andreas Heilos, Holger Hesse, Marc Schafer

Patent number: 8169441Abstract: A method and system for minimizing an amount of data needed to test data against subarea boundaries in spatially composited digital video is provided. Graphics data for a frame is composed of geometry chunks. Each geometry chunk is defined by its own bounding region, where the bounding region defines the space the geometry chunk occupies on the compositing window. Only the parameters that define the bounding region are communicated to each graphics unit in conjunction with the determination of which graphics unit will render the geometry chunk defined by the bounding region. The actual graphics data that comprises the geometry chunk is communicated only to those geometry units that will actually render the geometry chunk. This reduces the amount of data needed to communicate graphics data information in spatially composited digital video.Type: GrantFiled: April 11, 2011Date of Patent: May 1, 2012Assignee: Graphics Properties Holdings, Inc.Inventors: David R.

Publication number: 20110242114Abstract: A method and system for minimizing an amount of data needed to test data against subarea boundaries in spatially composited digital video. Spatial compositing uses a graphics unit or pipeline to render a portion (subarea) of each overall frame of digital video images. This reduces the amount of data that each processor must act on and increases the rate at which an overall frame is rendered. Optimization of spatial compositing depends on balancing the processing load among the different pipelines. The processing load typically is a direct function of the size of a given subarea and a function of the rendering complexity for objects within this subarea. Load balancing strives to measure these variables and adjust, from frame to frame, the number, sizes, and positions of the subareas. The cost of this approach is the necessity to communicate, in conjunction with each frame, the graphics data that will be rendered. Graphics data for a frame is composed of geometry chunks.Type: ApplicationFiled: April 11, 2011Publication date: October 6, 2011Applicant: Graphics Properties Holdings, Inc.Inventors: David R.
