Abstract: A feed station has a pre-separation region, a separation region and a transport region in succession along a transport path. A first sensor is at the start of the separation region and a second sensor is at the start of the transport region. A control unit processes signals from the sensors and encoders to determine the position of the flat item, and is connected with a separation motor to drive the separation device, so that a flat item is separated from a stack with a predetermined separation velocity. If unacceptably small gaps exist between the flat items, the separation process is stopped when the leading edge of a subsequent flat item reaches the second sensor and is continued when the preceding separated flat item achieves a predetermined clearance from the leading edge of the aforementioned flat item due to its transport.
Abstract: A machine vision system program editing environment includes near real time context generation. Rather than requiring execution of all preceding instructions of a part program in order to generate a realistic context for subsequent edits, surrogate data operations using previously saved data replace execution of certain sets of instructions. The surrogate data may be saved during the actual execution of operations that are recorded in a part program. An edit mode of execution substitutes that data as a surrogate for executing the operations that would otherwise generate that data. Significant time savings may be achieved for context generation, such that editing occurs within an operating context which may be repeatedly refreshed for accuracy in near real time. This supports convenient program modification by relatively unskilled users, using the native user interface of the machine vision system, rather than difficult to use text-based or graphical object-based editing environments.

Abstract: Method, article of manufacture and system using minimum data to determine whether a sliding-mode control should be applied in a plant. First measure the plant in an open-loop control fashion, and using the measured data, describe a state equation of the plant by system identification and order determination methods. Then design a switching hyperplane for sliding-mode control. Next, calculate higher order statistics on the difference between an output of a linear model on the hyperplane and an output of the sliding-mode control model in the measured data; When any of the higher order moments is larger than a predetermined threshold, configure a controller as a sum of the linear control input term and the nonlinear control input term. If both higher-order moments are smaller than the threshold, then configure the controller using only a linear control input term.

Assuming the different sides represent a combined signal value and an estimated combined signal value, respectively, the ECU calculates onboard identified values of the model parameters such that an identification error between the signal values is minimized, and calculates an air-fuel ratio correction coefficient using the identified values and a control algorithm derived from the control target model.
Abstract: In the area of storage management, service automation can be realized through the use of “MAPE” loop(s). A Planner (P) interacts with the Monitoring (M), Analysis (A) and Execution (E) components in a closed loop. For each new option or potential planning action the Planner (P) invokes the Analysis (A) component. The correctness, as well as effectiveness, of the planning decision is dependent on the Analysis (A) component. Embodiments can utilize an adaptive Analysis (A) component (i.e., an analysis component that can be retrained) that also associates a value of confidence and a corresponding error in the evaluation along with a predicted impact. The Planner (P) component uses this additional information for quoting the final impact of a particular planning action as part of an adaptive MAPE loop to provide improved resource utilization and resource management.

Abstract: In a computer-controlled conveying system (3), virtual markers (K1-K10) are generated and are stored in association with a conveying element (31, 32, 33, 34). The virtual markers (K1-K10) each comprise a marker position which is based on the current position of the conveying element (31, 32, 33, 34) at the time of generation. A search is carried out for stored virtual markers (K1, K5, K6, K9) which have a relative position with respect to the associated conveying element (31, 32, 33, 34) that lies within a defined sector (T1, T2, T3) at the search time. Actuators of the conveying system (3) are driven depending on whether virtual markers (K1, K5, K6, K9) were found in the defined sector (T1, T2, T3) during searching. The virtual markers (K1-K10) may be applied to the conveying elements (31, 32, 33, 34) with dynamically changing distances, for example, and make it possible to drive actuators in a flexible manner independently of a fixedly defined clock rate.

Abstract: A control system is described for controlling the operation of a target system, such as a data center. The control system uses a prediction module to predict demand for resources of the target system for future time steps. The control system then uses a transition determination module to determine state transitions within the target system to address the predicted demand. Each state transition describes a number of units to be advanced from a first state, at a first time step, to a second state, at a second time step. The control system then commences those state transitions which begin in the current step, and then repeats the predicting and determining for a next time step. The transition determination module can determine the state transitions by operating on an objective function that includes a demand difference component and a cost component, as subject to a set of conservation equations.
Abstract: Various embodiments are directed to systems and methods for optimizing energy use with one or more optimization engine objects. An optimization engine object may have a plurality of dependent objects including at least a dependent optimization engine object, or at least one of a supply-side or demand-side object. The optimization engine object may receive dependent object attribute data from each of the at least one dependent objects; determine an optimal configuration for the plurality of dependent objects over the first time period subject to at least one optimization constraint; and conditioned upon the optimization engine depending from a superior optimization engine, transmit a net energy usage associated with the optimal configuration to the superior optimization engine.
