    摘要: A method and apparatus for reducing switching noise in a system-on-chip (SoC) integrated circuit including an analog to digital converter (ADC) provides for reduced noise in the ADC conversions. Sampling circuits of the ADC are operated by sampling clock signals and digital circuits and other noise-generating circuits such as power converters, are operated by digital circuit clock signals. Both sets of clock signals are derived from the same master clock by a clock generator circuit, but an offset is applied in the clock generator circuit to move the edges of the digital circuit clock signals away from critical sampling intervals corresponding to edges of the sampling clocks. In one embodiment, the offset is applied by a processor core that forms part of the digital circuits by setting a value in the clock generator, which the clock generator then loads into the divider after halting the clock to the digital circuits.

    摘要: A split-type aerostatic bearing for supporting a moving table to move frictionlessly on a platform (4) is disclosed. The split-type aerostatic bearing includes an aerostatic bearing plate (6), air floating elements (2′a, 2′b, 2′c, 2′d) disposed on a bottom of the aerostatic bearing plate (6) and a vacuum pre-tightening structure (7) disposed on the aerostatic bearing plate (6). The vacuum pre-tightening structure (7) is coupled to the aerostatic bearing plate (6) in a split fashion. Separation of the air floating elements (2′a, 2′b, 2′c, 2′d) from the vacuum pre-tightening structure (7) prevents the aerostatic bearing plate (6) from bending under a vacuum pre-tightening force, and hence will not affect the air floating area.

    摘要: This invention provides a process for extracting the flavonoid and alkaloid components from lotus leaf and provides a method for the reduction of body weight, total cholesterol (TC), low density lipoprotein (LDL) cholesterol, and triglycerides (TG). It also provides a method for increasing high density lipoprotein (HDL) cholesterol and the prevention of coronary heart disease (CHD). There are 10% to 80% flavones and 10% to 80% alkaloids in the lotus leaf extract powder of this invention. This process produces an improved standardized raw material that may be utilized as a single dietary supplement, food additive, or medicine and it may be added to other plant extracts, nutraceuticals, or pharmaceuticals.
