The ladder program editing support apparatus includes the display that displays the ladder program, and an edit control unit that selects a selected range to be edited within the ladder program displayed on the display and displays identification information on the circuit elements included in the ladder program within the selected range on the display in the form of a list according to a preset displaying order.

A smart valve positioner is provided with a local user interface with but-tons and a display inside a positioner housing under a housing cover for locally operating the valve positioner. The valve positioner is further provided with a detector detecting whether the housing or the housing cover is open or closed. The operation mode of the local user interface is configured to be different depending on whether the housing or housing cover is open or closed. For example, a larger variety of operations may be available when the housing or housing cover is open.

The first terminal is configured to be a first port for the inductor. The second terminal is configured to be a second port for the inductor. The third terminal is a dummy terminal. In some implementations, the package substrate includes a solder resist layer over the dielectric layer, where the solder resist layer covers the third terminal. In some implementations, the package substrate includes a solder interconnect over the third terminal, such that the solder resist layer is between the third terminal and the solder interconnect. In some implementations, the package substrate is coupled to a die comprising a plurality of switches.

An operation of the machine is iteratively controlled with control inputs determined from an optimization of a cost function along a prediction horizon subject to constraints on the control inputs. The optimization is performed according to the model and the cost function includes at least one parameter of the model. During at least some iterations of the control, the parameter of the model is updated resulting in updating the cost function.

A controller for a rotary machine includes a processor and a memory coupled to the processor. The memory is configured to store operating modes of the controller. The operating modes include a normal operating mode and a fault tolerant operating mode. The controller is configured to receive a signal from at least one sensor and determine an operating state of the rotary machine based on the signal. The controller is also configured to switch the operating modes based on the determined operating state of the rotary machine and regulate at least one electromagnetic bearing and at least one flow control device. The controller is further configured to adjust at least one of the at least one electromagnetic bearing and the at least one flow control device in the fault tolerant operating mode.

According to some embodiments of the invention, an adjusting device for adjusting a passive drip irrigation valve to enable precision irrigation includes a device body configured to be at least one of hand-held or attachable to a robot, the device body having a manipulator end, and a manipulator assembly contained within and extending from the manipulator end of the device body. The manipulator assembly includes a coarse alignment adjustment assembly constructed and arranged to align the adjusting device with the passive drip irrigation valve. The manipulator assembly also includes a fine actuator configured to rotate the passive drip irrigation valve by a specified angle.

A method of operating a rotary machine. The method includes rotating a rotor; receiving current at at least one electromagnetic bearing supporting the rotor; detecting an operating characteristic of the rotary machine; determining, using a controller, an operating state of the rotary machine based on the detected operating characteristic; retrieving operating modes stored in a memory of the controller, the operating modes including a normal operating mode and a fault tolerant operating mode; switching between the normal operating mode and the fault tolerant operating mode, using the controller, based on the determined operating state of the rotary machine; regulating, using the controller, at least one of a magnetic force and a position of the at least one electromagnetic bearing; and regulating, using the controller, at least one of a position and an opening of at least one fluid flow control device.

By programming position parameters corresponding to user support surfaces of a power driven wheelchair, movement of the user support surfaces is automated. The user support surfaces can be positioned individually, as part of a sequence or as part of a series of sequences. Accordingly, with little effort, a user can position the user support surfaces of the wheelchair to a predefined position.

The invention relates to a method for actuating a mode selection switching element of an installation by means of a safe control operation, wherein the installation has a functional controller and communication connections, and wherein the functional controller has a storage unit, a (sequence) control apparatus, a display and a user interface. The method has the following steps: providing a mode-selection actuating element on a user interface; receiving a user input to change the operating mode at the user interface; transmitting the data relating to the change of operating mode to the mode-selection switching element; transmitting the data relating to the change of operating mode from the mode-selection switching element back to the functional controller; checking whether the operating mode of the data which have been transmitted back matches the operating mode selected by the user; transmitting a confirmation to the mode-selection switching element; and changing the operating mode by means of the mode-selection switching element.
