Abstract: Embodiments of this disclosure provides systems and methods for displays. In embodiments, a display system includes a frame, an eyepiece coupled to the frame, and a first adhesive bond disposed between the frame and the eyepiece. The eyepiece can include a light input region and a light output region. The first adhesive bond can be disposed along a first portion of a perimeter of the eyepiece, where the first portion of the perimeter of the eyepiece borders the light input region such that the first adhesive bond is configured to maintain a position of the light input region relative to the frame.

Abstract: An automation appliance and a method for operating an automation appliance are disclosed. Media data, particularly audio and/or video data, are used to display data relating to the status and/or to the configuration of the automation appliance. The disclosed method for operating an automation appliance significantly improves user guidance.

Abstract: A wide voltage converter includes a power-supply-side converter unit, n load-side converter units, and a step-up/step-down converter device having n transformers. The step-up/step-down converter device electrically connects the power-supply-side converter unit to the n load-side converter units. The wide-voltage-range converter is capable of operating without derating with n specified output voltages, which can be predetermined independent from one another, and reliably inhibits restart.

Abstract: A wide-voltage-range converter with a power-supply-side converter unit and a load-side converter unit includes a step-up converter electrically connecting the DC voltage sides of the power-supply-side converter unit and the load-side converter unit, respectively. The wide-voltage-range converter further includes a bidirectional switch and a turn-off semiconductor switch as converter unit valves in each phase (R, S, T) of the power-supply-side converter unit. The power-supply-side converter unit also includes a filter on the AC voltage side, whereas the load-side converter unit includes a DC voltage capacitor on the DC voltage side. The wide-voltage-range converter operates at a specified output voltage without derating.

Abstract: A digital counting method and device for evaluating a digital signal (S.sub.S) using a digital counter (Z) applies the digital signal (S.sub.s) that is received by the input (ZE) of the digital counter (Z) as an output signal (N+1) to represent another binary position, in addition to the output signals (N) from the digital counter (Z).

Abstract: In the regulation of the torque response of multiphase electronically commutated electric motors, in particular synchronous motors, a constant moment of rotation response is achieved by forming the nominal current values for the phases to be regulated depending on a torque-regulating variable and the rotor position. A current regulator is assigned to each current phase to be regulated. The method makes it possible to preset a nominal current value for each phase to be regulated for any adjustable torque as a function of the particular rotor position. The separate regulation of the nominal current values ensures that the up-commutating current is alternating exactly with the down-commutating current and hence no system-caused torque transients occur.
