There is provided a method of processing an ultrasound spectrum image. According to such method, a spectrum image is formed based on ultrasound data and then the noise is removed from the spectrum image. The noise-removed spectrum image is matched with one or more spectrum models representing specific spectrum types. Then, whether or not the noise-removed spectrum image contains an aliasing is checked. If the noise-removed spectrum image contains the aliasing, then the aliasing is removed from the noise-removed spectrum image to provide a noise-removed spectrum image without the aliasing. Thereafter, contour tracing is performed on the noise-removed spectrum image without the aliasing to detect contour points. Further, peak tracing is performed on the noise-removed spectrum image without the aliasing to detect peaks.

The present invention is a computer controlled display device. In one embodiment, the display device includes a flat panel display having an input for receiving display data. Additionally, a moveable assembly may be coupled to the display. The moveable assembly may provide at least three degrees of freedom of movement for the flat panel display device. Additionally, the moveable assembly may have a cross-sectional area, which is substantially less than a cross-sectional area of a display structure of the flat panel display.

Disclosed herein is a pressure-dependent automatic leak valve for sphygmomanometers which is able to regularly reduce the pressure in a cuff without manipulation of a pressure reducing valve. The pressure-dependent automatic leak valve of the present invention includes an outer casing, with an inlet port formed at a predetermined position in the outer casing so that air is drawn from the cuff into the outer casing, and an outlet port formed at a predetermined position in the outer casing so that the air, drawn through the inlet port, is discharged outside through the outlet port. The pressure-dependent automatic leak valve further includes a movable member which has a diameter smaller than an inner diameter of the outer casing and inserted into the outer casing, and a spring which supports the movable member in the outer casing. In the present invention, the height of the movable member is changed according to the pressure in the cuff. Fluid resistance of air to be discharged through the pressure-dependent automatic leak valve is automatically changed in proportion to the height of the movable member, so that air is discharged at a constant rate. Thereby, the pressure in the cuff is reduced at a constant speed.

Disclosed relates to a method for improving a conversion rate of oil soluble unsaturated lipids into water-soluble lipids and, more particularly, to a method for improving a conversion rate of oil soluble unsaturated lipids into water-soluble lipids that forms an unsaturated lipid-chloride derivative having an increased reaction activity by using a pyridine-thionyl chloride as a catalyst, not directly causing a reaction between the unsaturated lipids and amino acids, or that applies an emulsifier to cause a reaction between the unsaturated lipids and amino acids so as to minimize the size of lipid particles to a nano-size of less than 50 nm, thus improving the reaction conversion rate to more than 99%.
摘要:
The invention provides a camera module in which lens frames having lenses are assembled together by stacking. The camera module includes a first lens frame having at least one first lens therein, and at least one second lens frame fastened with the first lens frame. The second lens frame has a second lens fixed therein in optical alignment with the first lens. An image sensor is disposed in the lower portion of the second lens frame to sense an image of an object introduced through the lenses. The invention allows combinations of diverse forms of lenses, and further, the second lens frame can be additionally assembled to adjust the number of lenses in the module.
摘要:
A computer controlled display device. In one embodiment, the computer controlled display device includes a flat panel display having an input for receiving data and a moveable assembly coupled to the display. A motor may be operatively coupled to a tension device disposed within the moveable assembly. The motor applies a force to the tension device to suspend movement of the moveable assembly, and also releases the force to permit movement of said moveable assembly.
