摘要:
The present invention provides an extraction method for the leaves of Ilex kudingcha C. J. Tseng, and the total saponins from I. kudingcha leaves extracted by using this method, and use of the total saponins in preparing a drug for reducing cholesterol and blood lipids and anti-atherosclerosis. The extraction method comprises the following steps: subjecting I. kudingcha leaves to refluxing extraction with ethanol aqueous solution to obtain an extracted solution; filtering the extracted solution and removing ethanol, and then separating and purifying the solution using a macroporous resin column.

Methods for detecting or diagnosing cancer in a subject are provided herein. Such methods may include, but are not limited to, measuring a test level of 5hmC in a biological sample from the subject; and determining that the subject has a malignant cancer when the test level of 5hmC is lower than that of a control level of 5hmC. Such methods may further include a step of measuring a test level of Ki67 in the biological sample and determining that the subject has a malignant cancer when the test level of Ki67 is higher than that of a control level of Ki67.

The present invention provides a method and device for generating a filter coefficient in real time. The method includes: looking up a converted window function value in a converted window function table based on a current coefficient index; generating a current cut-off angular frequency; generating a look-up table address based on the current coefficient index, the filter order and the current cut-off angular frequency and looking up a sine value in a sine table based on the look-up table address; and multiplying the converted window function value by the sine value to obtain the filter coefficient. The device includes a first memory, a second memory, a look-up table address generation module and a first multiplier. The present invention is easily implemented with low hardware resource consumption and high flexibility, and is particularly applicable for the hardware implementation of high-order finite impulse response filters.

A method and apparatus for scan conversion and interpolation of linear array steering imaging in an ultrasonic system are disclosed. The method computes the points that are most related to the point to be interpolated in the principal direction of the point spread function and performs interpolation in the principal direction of the point spread function according to the steering angle of the scan lines so as to obtain a more accurate interpolation result.

A soleplate includes a metallic layer, a non-ferromagnetic layer and a ferromagnetic layer sandwiched between the metallic layer and non-ferromagnetic layer. The soleplate is used in an induction heating-based cordless iron. The electromagnetic field from an induction coil located in a stand, where the iron rests and gets charged, can pass beyond the non-ferromagnetic layer and heat the ferromagnetic layer efficiently. The non-ferromagnetic layer that is forming an ironing plate ensures a uniform heat transfer to the metallic layer for good steaming performance for effective cordless ironing.
摘要:
A steaming system (100) comprises a steam generator (120), a removable water tank (130) for holding and supplying water to the steam generator (120); and a dosing device (140) for supplying an amount of a water treatment agent to the water tank (130). The dosing device is configured to be triggered by a movement of the water tank (130) relative to the steam generator (120).

An apparatus includes a Universal Serial Bus (USB) transceiver of a USB host controller, a first pull-down resistor, a first switch, a second pull-down resistor, a second switch, and a detachment module. The USB transceiver has a differential output. The first switch electrically couples the first pull-down resistor to a positive terminal of the differential output in response to a first switch control signal. The second switch electrically couples the second pull-down resistor to a negative terminal of the differential output in response to a second switch control signal. The detachment module selectively determines whether a USB device is electrically coupled to the differential output by checking a voltage at the differential output while at least one of the first switch control signal or the second switch control signal is asserted. The detachment module determines whether the USB device is electrically coupled to the differential output by checking the positive terminal when the USB transceiver is in a full-speed idle state and by checking the negative terminal when the USB transceiver is in a low-speed idle state.
摘要:
A system allows one or more hybrid hard disks or any other storage devices to share a logical nonvolatile device formed by one or more non-volatile memory devices. The system comprises a control logic to reserve on a hybrid hard disk a space that corresponds to a non-volatile memory device in the hybrid hard disk and to use a space access instruction to access the non-volatile memory device. The control logic accesses the logical non-volatile memory device in an event that a content of a storage device is stored in the logical non-volatile memory device in response to an instruction to access the storage device.
