A blood oxygenator wherein blood and oxygen are admixed by flowing blood, into which has been introduced bubbles of oxygen, through a three-dimensional, open cellular mixing material having a substantial void volume. The resulting arterialized blood and blood foam rise to the top of the admixing chamber and are contained in a channel located at the top of the chamber and directed through this channel to the input of a defoamer chamber. A defoamer filter of annular configuration is retained within the defoamer chamber such that the defoamer inlet is located at the top of the defoamer filter within the interior annular space thereof. The blood foam thus enters the interior of the defoamer filter and is distributed over a substantial portion of the defoamer surface and collapsed therein to remove substantially all entrapped gases. The oxygenated defoamed blood collects at the bottom of the defoamer chamber for return to the patient's body. In the preferred embodiment, the defoamer chamber is provided with an unobstructed annular defoamer filter inlet opening for enhanced contacting of the defoaming material by the blood and blood foam while minimizing blood hemolysis, and an integral vent which permits the entrapped gases to be exhausted from the oxygenator either by free flow or by a vacuum source.

A blood oxygenator wherein blood and oxygen are admixed by flowing blood, into which has been introduced bubbles of oxygen, through a three dimensional, open cellular mixing material having a substantial void volume. In one embodiment, the admixing chamber is provided by an upright cylinder having an open interior. In a second embodiment, the chamber has an annular interior configuration. In both embodiments, the open cellular mixing material completely fills the cross-sectional interior of the chamber. The resulting arterialized blood and blood foam rise to the top of the admixing chamber and are contained in a channel located at the top of the chamber and directed through this channel to the input of a defoamer chamber. A defoamer filter of annular configuration is retained within the defoamer chamber such that the defoamer inlet is located at the top of the defoamer filter within the interior annular space thereof. The blood foam thus enters the interior of the defoamer filter and is distributed over a substantial portion of the defoamer surface and collapsed therein to remove all entrapped gases.

Systems and methods for in-field camera calibration in a stereovision system may include using a plurality of cameras to capture an image pair, the image pair comprising images of a scene; identifying infinite points on the images of the image pair using a calibration circuit; the calibration circuit determining a disparity amount between corresponding infinite points for each camera; and the calibration circuit determining an inverse operation to reduce the determined disparity amount between the corresponding infinite points. Systems and methods may also include a calibration circuit identifying corresponding points, in which the corresponding points include a point on a first image of an image pair corresponding to a point on a second image of the image pair; determining a translational disparity amount between the corresponding points for each camera; and determining an inverse operation to reduce the determined translational disparity amount between the corresponding infinite points.
