Abstract: A boost snubber circuit structure applied in a power supply having a boost circuit and a power conversion unit, wherein the boost circuit includes a boost unit connected to a switch element, a boost control unit for generating a driving signal to drive the switch element to control the charge/discharge of the boost unit, and a boost snubber unit for obtaining a voltage difference between a reference voltage and a detection signal and modulating the magnitude of the reference voltage or the detection signal to change the voltage difference and control the duration of outputting the driving signal. The voltage difference between the reference voltage and the detection signal determines the duration of outputting the driving signal. By controlling the voltage difference between the detection signal and the boost level, the invention prevents an occurrence of an inrush current caused by a too-large duration of generating the driving signal.

Abstract: A ground coffee extraction apparatus has a base to which a filter cup loaded with ground coffee is assembled from below. A delivery system pumps cool water from a cool water tank into the extraction apparatus. The cool water exerts a downward force greater than a resilient force of resilient elements of the extraction apparatus to drive a sliding element and a downward pressing element downward. Consequently, an O-ring seals a gap between the downward pressing element and the filter cup while the downward force is evenly applied to the ground coffee in the filter cup, thereby sealing and compacting the ground coffee hydraulically. After coffee is extracted, the cool water is drawn back into the cool water tank so that the sliding element and the downward pressing element are moved upward to unseal the filter cup. Hence, the automatic extraction apparatus enables rapid, uniform, and standardized sealing and compacting.

Abstract: We discovered that a polymorphism in the promoter of the VKORC1 gene is associated with warfarin sensitivity. This polymorphism can explain both the inter-individual and inter-ethnic differences in warfarin dose requirements. Furthermore, the polymorphism is also associated with promoter activity. Thus, the promoter sequence or activity of the VKORC1 gene of a subject can be used to predict how much warfarin should be prescribed for the subject. Relevant methods and compositions are provided.
