The asset information is associated with the asset identifier, and the asset information and the asset identifier are stored in a database system. | 10-06-2011 |
20120101985 | TRIGGERING ACTIONS IN AN INFORMATION FEED SYSTEM - Disclosed are systems, apparatus, methods, and computer readable media for performing actions in response to information updates provided in an information feed. In one implementation, an information update to be displayed in an information feed may be received. The information feed may be capable of being displayed on a display device. The information update may be associated with a data object. A determination may be made as to whether the information update includes a designated keyword, the keyword being designated in association with a first user account. When the information update includes the designated keyword, a data value may be set to an indication that the first user account is following the data object such that updates related to the data object are capable of being stored as feed items in a feed table. | 04-26-2012 |
20120102063 | TRIGGERING ACTIONS IN AN INFORMATION FEED SYSTEM - Disclosed are systems, apparatus, methods, and computer readable media for performing actions in response to information updates provided in an information feed. In one implementation, an information update is selected for comparison with a data record creation rule. The data record creation rule may specify a data record creation operation for creating a data record based the selected information update. The selected information update may be capable of being displayed in an information feed. A determination may be made as to whether the selected information update includes information satisfying a trigger condition associated with the data record creation rule. When the information in the selected information update satisfies the trigger condition, the data record creation operation may be performed to create the data record. The data record creation operation may identify information to include in the data record. | 04-26-2012 |
20120102153 | TRIGGERING ACTIONS IN AN INFORMATION FEED SYSTEM - Disclosed are systems, apparatus, methods, and computer readable media for performing actions in response to information updates provided in an information feed. In one implementation, an information update to be displayed in an information feed is received. The information feed may be capable of being displayed on a display device. The information update may be stored in a feed table for display in the information feed. A determination may be made as to whether the information update includes information satisfying a trigger condition associated with a trigger rule. When the information in the information update satisfies the trigger condition, the trigger rule may be activated. The trigger rule may specify a trigger action to perform in association with the information update. | 04-26-2012 |

20080269011 | System for controlling a machine with a continuously variable transmission - A system for controlling a machine with a continuously variable transmission includes a first control device configured to produce a first signal based on a first operator input and a second control device configured to produce a second signal based on a second operator input. The system also includes a control system configured to receive the first and second signals from the first and second control devices and generate a raw torque value based on the first and second signals. The control system is also configured to determine an output torque value based on the raw torque value and transmit the output torque value to the transmission to control the transmission. | 10-30-2008 |
20090005914 | FEEDBACK ACCELERATION REDUCTION FOR FLUID SUPPLY VALVES - A system and method for controlling a variator operate to detect variator torques and/or internal pressures and generates a preliminary corrective command. The preliminary corrective command is transformed via a dynamic transform to account for system characteristics during transient operating conditions such as machine acceleration, such that the acceleration of the system during transient periods is not torque-limited by static torque-control map values. In an embodiment, the acceleration may be positive or negative, and in a further embodiment, braking is automatically applied in the case of negative requested power or desired machine retarding. | 01-01-2009 |
20090156360 | PART-THROTTLE PERFORMANCE OPTIMIZATION - A system and method for optimizing machine performance using speed shaping in a machine having an engine and a drivetrain implementing engine underspeed module receives a throttle command requesting an increase in engine speed and transmits the throttle command to the engine. If the requested increase exceeds a predetermined function, the predetermined function is forwarded to the engine underspeed module as a speed standard. The engine underspeed module determines whether the actual engine speed attained by the engine is less than the speed standard by more than a predetermined gap value and, if so, reduces the power required by the drivetrain to avoid lugging of the engine. | 06-18-2009 |
20090199814 | POWER-BASED UNDERSPEED CONTROL - A method of adjusting the operation of an engine-driven machine to avoid engine under-speeding entails converting a received speed or torque command into a power command. When an engine under-speed condition is sensed, the system performs underspeed correction in the power domain before converting the underspeed processed power command back into the units of the original domain. The converted underspeed processed power command is issued to the transmission or other component to alleviate the engine under-speeding condition. | 08-13-2009 |
20100007300 | Method and system for temperature-based power converter control - A method of controlling a power converter in an electric drive machine is disclosed. The method may include determining a first switching frequency and determining a second switching frequency. The method may also include comparing the first switching frequency and the second switching frequency. The method may further include selecting a power converter switching frequency from the lesser of the first switching frequency and the second switching frequency to control a power converter. | 01-14-2010 |
20140210208 | Dual Generator Single DC Link Configuration for Electric Drive Propulsion System - A machine is described that includes an electric drive for propelling the machine along a ground surface.
