A quantification method and an imaging method are disclosed, capable of quantifying the margin feature, the cysts feature, the calcifications feature, the echoic feature and the heterogenesis feature of a tumor, and capable of imaging the margin feature, the cysts feature, the calcifications feature and the heterogenesis feature of a tumor. The quantification method and the imaging method calculate the moving variance of the gray scale of each of the pixel points based on the gradient value of the gray scale of these pixel points. Then, depending on the purpose of the quantification method or the imaging method, the maximum value, the minimum value, the mean value, and the standard deviation of the moving variance of the gray scale of these pixel points are calculated, respectively. At final, with the definition of the threshold value and the imaging rule, the above features of the tumor are quantified or imaged.

The present invention relates to a method for multi-layer classifier applying on a computer readable medium for classifying multiple image samples. The method at least comprising the following steps: (a) receiving a plurality of samples; (b) providing a plurality of attributes, and evaluating a significance of the attributes by a selection criterion; (c) selecting at least one cut-point to establish a discriminant analysis model; (d) proceeding a step of evaluating a performance of the discriminant analysis model by adding the attributes to the discriminant analysis model; and (e) providing a stop criterion. The present invention also provides a computer readable medium for classifying multiple image samples by using the method for multi-layer classifier.

The present invention related to a method for retrieving a tumor contour of an image processing system that includes a memory storing a grayscale image and a processor, comprising: receiving an input tumor contour of the grayscale image; defining a tumor contour annular region and a plurality of reference segments of the grayscale image, wherein the input tumor contour is in the tumor contour annular region, and each of the plurality of reference segments is across the tumor contour annular region and includes a plurality of measured points; retrieving a tumor contour suggestion point on each of the plurality of reference segments; and linking all the tumor contour suggestion points on all of the reference segments, for forming the tumor contour. Accordingly, by applying the method of the present invention, a doctor can rapidly and accurately identify the contour of a tumor in a grayscale image.

A connection assembly has a male connector, a first engaging ring securely mounted on the male connector, a female connector and a second engaging ring securely received in the female connector. The first engaging ring has first claws formed to abut a periphery defining the second annular groove formed on the female connector and the second engaging ring has second claws formed to abut a periphery defining the first annular groove formed on the male connector. Engagement between the male connector and the female connector is accomplished after the abutment between the first claws and the second annular groove and between the second claws and the first annular groove is finished.

A self-locking quick release coupler includes a handle and a lever. The first distal end of the handle is adapted to be secured to a side face of the groove adapter. The handle has a head formed on the first distal end thereof. The head is extendable into a side face of the groove adapter so as to secure a tube inserted into the groove adapter. The lever partially extends through the handle to be pivotably received in the handle. The lever has a hook formed on a first distal end of the lever to adapt to hook a pin of the groove adapter and a press formed on a second distal end of the lever. The pivotable movement of the lever allows the hook of the lever to selectively hook the pin so as to secure the handle relative to the groove adapter.

A self-locking quick-disconnect coupling device includes a female coupler including a stop formed thereon and an opening defined therethrough. A male adaptor through which a recess is defined is insertable into the female coupler. A cam handle includes a handle portion and a cam portion rotatably mounted on the coupler between a releasing and an engaging position so that the cam portion is moved through the hole into the recess. A hooking element is pivotably linked to the handle portion. The hooking element includes a barb projecting therefrom and including an inclined surface. A locking control element including first and second distal ends is pivotably linked to the handle portion. The inclined surface will slide on the stop when the cam portion is pivoted from the releasing position to the engaging position thus allowing the barb to snap into engagement with the stop when the cam handle is in the engaging position.

A bucket valve with a removable handle includes a tubular valve body, a piston disposed with the valve body and a crank arm integrally formed of a central sleeve and two spaced fingers. The fingers are pivotally retained to the piston. A drive shaft is drivingly disposed in and extends from the central sleeve of the crank arm to project through and beyond the valve body to connect by a distal tip thereof to a handle via an axle sleeve. An `L`-shaped latch is resiliently retained in the axle sleeve whereby the combined axle sleeve and handle are removably retained to the drive shaft. The handle has a forked tip forming an outer upper face, a central fork and an outer lower face against each of which a knob can abut in a first, second and third position respectively.

Bucket valve with removable handle

A device for locking a lever for pivoting a valve contained in a valve housing. A recess is formed in the valve housing. An annular groove is formed in the recess. A spring is sited in the recess. A latch has a relatively large middle section connecting an upper section with a lower section. The latch is sited in the recess so that the lower section thereof is inserted in the spring and that the middle portion thereof is sited on the spring. A C-ring engages in the groove so that the latch is trapped in the recess. A hole is formed in the lever. The hole has an upper section and a relatively large lower section. A wedge surface is formed on the underside of the lever. A button has a body connecting with a relatively large head and a groove formed about the body. The body of the button is inserted through the upper section of the hole. A C-clip engages in the groove formed about the body so that the button is trapped in the hole. The spring biases the upper section of the latch into the hole when the recess aligns with the hole so that the lever is retained in an open position. The upper section of the latch moves into the recess when the button is pressed, so that the lever is released from the open position. The wedge surface presses the upper section of the latch into the recess while passing by the same so that the recess can align with the hole.
