摘要： A cutter hub and blade assembly (10, 22, 60) for cutting polymer strands extruded from a die face (16) in a pelletizer has cutter blades (14, 24, 62) mounted on the cutter hub (48) at a steep angle. The blades (24, 62) are beveled along a portion of their leading edge to form a blunt cutting edge (36, 38) or surface (40, 42, 64, 66) to the blades which is generally perpendicular to the die face. By beveling the leading edge of a blade (24) supported at a steep angle to form a blunt cutting edge (36), the bottom surface area (54) of the blade (24) in contact with the die face can be significantly reduced. The reduced contact area provides several advantages including a clean cut of the pellets and a faster blade grinding when seating the blades to the die face.

摘要： Apparatus and method for eye gaze tracking in human or animal subjects without calibration of cameras, specific measurements of eye geometries or the tracking of a cursor image on a screen by the subject through a known trajectory. One embodiment includes one uncalibrated camera for acquiring video images of the subject's eye(s) and optionally having an on-axis illuminator, and a surface, object, or visual scene with embedded off-axis illuminator markers. The off-axis markers are reflected on the corneal surface of the subject's eyes as glints. The glints indicate the distance between the point of gaze in the surface, object, or visual scene and the corresponding marker on the surface, object, or visual scene.

摘要： A system and method for eye gaze tracking in human or animal subjects without calibration of cameras, specific measurements of eye geometries or the tracking of a cursor image on a screen by the subject through a known trajectory. The preferred embodiment includes one uncalibrated camera for acquiring video images of the subject's eye(s) and optionally having an on-axis illuminator, and a surface, object, or visual scene with embedded off-axis illuminator markers. The off-axis markers are reflected on the corneal surface of the subject's eyes as glints. The glints indicate the distance between the point of gaze in the surface, object, or visual scene and the corresponding marker on the surface, object, or visual scene. The marker that causes a glint to appear in the center of the subject's pupil is determined to be located on the line of regard of the subject's eye, and to intersect with the point of gaze. Point of gaze on the surface, object, or visual scene is calculated as follows. First, by determining which marker glints, as provided by the corneal reflections of the markers, are closest to the center of the pupil in either or both of the subject's eyes. This subset of glints forms a region of interest (ROI). Second, by determining the gaze vector (relative angular or cartesian distance to the pupil center) for each of the glints in the ROI. Third, by relating each glint in the ROI to the location or identification (ID) of a corresponding marker on the surface, object, or visual scene observed by the eyes. Fourth, by interpolating the known locations of each these markers on the surface, object, or visual scene, according to the relative angular distance of their corresponding glints to the pupil center.

摘要： An aeration device pertaining to the technical field of sewage treatment includes a flow mixing chamber and an air inlet chamber. The flow mixing chamber has a liquid inlet opening, a liquid outlet opening, and an air inlet hole penetrating the chamber wall and located inside the air inlet chamber. The air inlet chamber has an air inlet opening and an interior space whose cross-sectional area is gradually reduced along the liquid flow direction in the flow mixing chamber. The cross-sectional area and number of the air inlet hole can be properly set in order for the mixed fluid produced by the aeration device to have relatively high-density small-diameter air bubbles that contribute to mixing the liquid flow and air flow sufficiently, dissolving oxygen rapidly and sufficiently into the liquid flow, increasing the oxygen dissolution rate of the mixed fluid, and enhancing aeration efficiency.
