Abstract: The invention is directed to methods and devices to improve light patterns used to inform or assist an observer or a driver. The invention is related to an illuminating device and to a method for projecting a pre-definable light pattern using the illuminating device of the vehicle into an area surrounding the vehicle. According to the invention, a projection surface is determined in the area surrounding the vehicle, a position of a predefined observer has been determined or provided, and a light unit of the illuminating device is controlled pixel-wise according to the determined projection surface and the determined position of the predefined observer in order to produce the pre-definable light pattern.

Abstract: According to various embodiments, a method for operating a switching converter includes determining an operating parameter of the switching converter and, if the operating parameter is outside a first operating range, adjusting a control parameter in order to adjust the operating parameter to be within the first operating range. The operating parameter includes at least one of a switching frequency of the switching converter and a current ripple value of an output current.

Abstract: An apparatus, system and method of controlling heated air drying of product. Exhaust temperature is measured during drying and compared to a target or ideal exhaust temperature function or reference. The exhaust temperature function or reference is correlated to a target or ideal drying rate for the product. Drying factors are adjusted to compensate for variance between measured exhaust temperature and the target or ideal exhaust temperature function to influence actual exhaust temperature to follow the target or ideal exhaust temperature function during drying. Drying factors such as inlet air temperature and drying pressure can be controlled manually or automatically by the comparison to promote efficient and controlled drying.

Abstract: The present invention refers to an apparatus for measuring the level and/or volume of a liquid stored in a container. The apparatus comprises at least one pair of electrodes mounted in the interior of the container in such a position that said electrodes are partially or totally immersed in the liquid stored in the container, said pair of electrodes acting as one of the capacitors of a Wien bridge to modify the output signal generated by the bridge-circuit to, in addition to measuring and indicating the volume of the liquid, also providing an indication of the quality of the liquid in the container and/or the ratio between two different types of liquid stored in the container.
