A display device for process automation includes a display unit, a controller, a current loop interface and a fieldbus interface. The display device is designed for power supply via the current loop interface, and the controller is designed to assign an analog coded signal of an output data present at the current loop interface to a first input data and to display the first input data via the display unit. The controller is designed to request the transmission of the output data in the form of a digitally coded signal via the fieldbus interface, to receive the digitally coded signal via the fieldbus interface, to assign the digitally coded signal to a second input data, to perform a comparison between the first input data and the second input data, and to display a result of the comparison via the display unit.

Systems and methods for detecting and accommodating for loss of a torque signal of a gas turbine engine are described herein. An engine deterioration offset may be determined while the torque signal of the engine is available. Then, in the event that the torque signal is lost, a predicted operating offset may be determined. A synthesized torque signal may be generated when the torque signal is lost at least in part from the engine deterioration offset and the predicted operating offset.

A system and method for designing scleral lenses includes a computer, a camera and a lathe connected by a network. The camera captures a set of sagittal images at each of a set of sagittal planes of an eye. A combined sagittal image is created from each set of sagittal images. A spline curve is defined for each combined sagittal image creating a set of spline curves. A set of back surface curves is created from the set of spline curves. A back lens surface is generated from the set of surface curves. A front lens surface is generated adjacent the back lens surface. A point cloud is generated from the back lens surface and the front lens surface. The point cloud is converted to a lens image. The lens is converted to a text file for use by the lathe to cut the scleral lens.
