A septum (1) is held in the cavity of a cover (6) and mounted on a pedestal (7) forming part of a flow channel, and comprises a main body having a through passageway and compression ribs formed in the sides thereof. In the main body, the vertical diameter of the cross section orthogonal to the through passageway is longer than the transverse diameter, and the through passageway includes a vertical diameter direction slit (4) formed in the vicinity of the outer end surface of the main body, and a hole (5) that is formed in a region extending from the slit to the inner end surface of the main body and whose cross section is spindle-shaped having a longer axis extending in the vertical diameter direction. The compression ribs are formed in the opposite sides of the main body in the transverse diameter direction, and the cavity of the cover is of circular cross section whose diameter is shorter than the outer surface spacing between the compression ribs. With the septum mounted, a space is defined between part of the surface of the main body and the inner wall surface of the cover. Further, the hole is closed by a compressive force acting on the septum from the inner wall surface of the cover through the compression ribs. The through passageway in the septum hardly forms a dead space that would cause a residual liquid therein, and the slit in the septum surface hardly opens even at the time of pressurization.

Spherical head assembly for attaching an optical and / or electronic device to a stander with an adjustability in at least two degrees of freedom, which has a first part that can be releasably connectedto the stander and a second part which is provided with a support element for the releasable connection of the device to be held thereby, and one of the two parts is a spherical head (20, 100) that has a body (21, 99) which has at least in part a spherical shape, and the other part comprises a cavity formed as a spherical segment which encircles the spherical head (20, 100) at least in part and is fitted thereto, and comprises an adjusting means for coupling the two parts together and releasing the same coupling, and in the initial position of intended use the held device is adjusted in horizontal or almost horizontal position. In the second part a groove (24, 108) is provided that has a vertical central plane and extends along the largest diameter of the spherical segment, and on the first part a circularly symmetrical stud (25, 103) is provided at a position that corresponds to the vertical diameter of the spherical segment and the stud (25, 103) can be fitted in the groove (24, 108), and in the fitted position the stud (25, 103) allows the displacement of the two parts along the groove (24, 108), and the stud (25, 103) allows the turning of the two coupled spherical fitted segments around the vertical axis of the stud (25, 103) at each of the adjusted positions, and the adjusting means is arranged on that one of the two parts which has the spherically shaped cavity, and when the position of two parts are fixed the adjusting means presses the cavity to the spherical body (21, 99).

The invention relates to an automatic leveling device of a gas holder piston. Four same weight boxes and four same horizontal detectors are respectively and symmetrically distributed on a round piston along the circumference uniformly, and each weight box and the corresponding horizontal detector are positioned on the same radius. The device is characterized in that each weight box is filled with fluids, and a liquid position meter is equipped on each weight box; the horizontal detectors are piston horizontal detectors, and are used for detecting the titling degrees along two mutually vertical diameter directions for the piston; the device also comprises a liquid level adjusting system which can convey fluids in a weight box at the downward tilting part to a weight box at the upward tilting part according to the detection result so as to implement the piston leveling. The titling problem of the piston can be automatically, accurately, rapidly and safely solved by using the device.

The embodiment of the invention discloses a measurement method of an amniotic fluid index, which comprises the following steps that: obtaining a key frame image corresponding to each quadrant in a target object, the target object being divided into a plurality of quadrants, each key frame image comprising a maximum amniotic fluid pool area corresponding to the corresponding quadrant; Positioning position information of a maximum vertical diameter line from each key frame image; Determining the maximum vertical diameter line length according to the position information of each maximum verticaldiameter line; And summing the maximum vertical diameter line lengths to determine the amniotic fluid index of the target object.
