Provided is an apparatus for connecting two sub-flow systems (e. g. airplane fuel tanks) and conveying a fluid between the two sub-systems using a pressured balanced transfer tube, particularly when there are large radial and axial movements or offsets between the sub-systems. Unlike conventional fluid transfer systems, the present apparatus allows for the pressure in the transfer tube to be balanced to internalize the pressure forces and prevent the exertion of pressure forces on the sub-systems connected to the transfer tube.

The invention provides a novel method of high-resolution quantifiable pulmonary regional ventilation imaging using a package of computer programs, including deformable image registration and local volume change calculation on 4-D or breath-hold CT images. High resolution 3D ventilation images have been generated using this technique with superior quality. The deformation matrices between different respiration phases are calculated using deformable image registration and applied to calculate local volume change ΔV between respiration phases. The invention provides less image-noise and mismatch sensitivity than other techniques based on CT images, and is less expensive than nuclear medicine imaging. Implemented clinically, the method can derive a patient's pulmonary ventilation information from the same set of 4-D CT images, providing a cheaper but more accurate method to generate clinical lung ventilation image. Such information can be utilized in treatment planning sparing functional lung volumes without additional procedure and cost for lung functional imaging.

A female coupler for a breakaway thread-lock quick disconnect coupling having a retainer wire positioned interiorly of an outer housing and a coupler support portion that prevents contamination of the retainer wire and a capture space formed by grooves in the outer housing and an inner housing, which may prevent degradation of performance and/or decrease the chances that the retainer wire is dislodged.

A dual walled transfer tube connecting two sub-flow systems and conveying the system fluid from one subsystem to another when there are large radial and axial movements or offsets between the connecting ends of the subsystem. The dual walled transfer tube has a fitting at either end and a single ball joint proximate each fitting to allow the transfer tube to accommodate changes in radial position of the fittings. The dual walled transfer tube utilizes a main inner fluid passage and an outer secondary fluid passage, each fluid passage having a slip joint to allow the transfer tube to accommodate changes in axial length between the fittings.

A zero-flow thread-lock quick connect/disconnect coupling having male and female couplers that enhance the fire-resistance capability of the coupling in a zero-flow pressurized state. The couplers include a fire-resistant seal assembly including a seal ring and non-metallic backup rings disposed. A first backup ring is made with a high-temperature non-metallic material and is formed as a delta ring for enhancing sealing performance during a fire event. A second non-metallic backup ring is formed as a half-delta ring between first and third backup rings. The third backup ring is made with a non-metallic material that is softer than the first and second backup rings and which abuts the seal ring. The female coupler includes a bearing ring that operatively connects a rotatable threaded support to the coupler body, a protrusion-slot interface between an actuating sleeve and the rotatable support, and a seal in the actuating sleeve for damping and/or debris-resistance.

Embodiments of the invention relate to a method and apparatus for displaying information. In a specific embodiment, at least two pluralities of voxel values for a corresponding at least two functions with respect to at least a portion of a subject can be obtained. The at least a portion of the subject can have a plurality of local volume elements, where the at least two pluralities of voxel values for the corresponding at least two functions each correspond to the plurality of local volume elements. In this way, there is a voxel value for each function for each local volume element of the portion of the subject. Each of the at least two pluralities of voxel values represents the value of the corresponding function of the at least two functions for the corresponding plurality of local volume elements. A representation is created where the value of one of the at least two functions is on a first axis and a count of voxels is on a second axis. The count of voxels on the second axis is at least a portion of the count of voxels having the value of the one of the at least two functions on the first axis. In another embodiment, the value of the other one of the at least two functional mechanisms can be on a third axis. The count of voxels on the second axis can then be the count of voxels having the value of the one of the at least two functional mechanisms on the first axis and having the value of the other one of the at least two functional mechanisms on the third axis.

A prediction system for grouping hepatocellular carcinoma includes an image capturing unit and a non-transitory machine readable medium. The non-transitory machine readable medium storing a program which, when executed by at least one processing unit, predicts a hepatocellular carcinoma group of the subject patient with hepatocellular carcinoma. The program includes a reference database obtaining module, a first image preprocessing module, a feature selecting module, a classifying module, a second image preprocessing module and a comparing module.

A receiver includes: an automatic gain controller (AGC) configured to receive an analog signal; an analog-to-digital converter (ADC) configured to receive an output from the AGC and to output a digitized signal, wherein a most significant bit of the digitized signal corresponds to a sliced data, and a least significant bit of the digitized signal corresponds to an error signal; and an adaptation unit configured to control the AGC, the ADC, or both the AGC and the ADC, based at least in part on the digitized signal to achieve a desired data digitization and data slicing.
