Abstract: A circuit includes a voltage divider circuit configured to generate a feedback voltage according to an output voltage, an operational amplifier configured to output a driving signal according to the feedback voltage and a reference voltage and a pass gate circuit including multiple current paths. The current paths are controlled by the driving signal and connected in parallel between the voltage divider circuit and a power reference node.

Abstract: A semiconductor device includes a substrate and a gate structure. The gate structure is disposed on the substrate, and the gate structure includes a titanium nitride barrier layer a titanium aluminide layer, and a middle layer. The titanium aluminide layer is disposed on the titanium nitride barrier layer, and the middle layer is disposed between the titanium aluminide layer and the titanium nitride barrier layer. The middle layer is directly connected with the titanium aluminide layer and the titanium nitride barrier layer, and the middle layer includes titanium and nitrogen. A concentration of nitrogen in the middle layer is gradually decreased in a vertical direction towards an interface between the middle layer and the titanium aluminide layer.

Abstract: A building information modeling (BIM) feedback system has at least one data system, a model presentation server system, a user device, and an information feedback database management system (DBMS). The data system receives objects posted by the model manager and then retrieves information of a building model and object mapping information, wherein the object mapping information records the relation between object identifications and the retrieved objects. Via the user device, a user views the building model and manipulates to generate feedback information, wherein the feedback information has an object data structure having the object identification and the parameters associated with the object which has the parameters to be updated. Based on the object mapping information, the information feedback DBMS requests the corresponding data system to update the parameters of the corresponding object according to the feedback information.

Abstract: A correlated color temperature control system (1) for a LED lighting system (2) having at least two LED sources (3, 4) with different correlated color temperatures. The LED lighting system (2) has a combined correlated color temperature resulting from the combination of the different correlated color temperatures of the at least two LED sources (3, 4), and a combined luminous flux resulting from the combination of the luminous fluxes of the at least two LED sources (3, 4), with each LED source being supplied with a supply current.
