    摘要: A method of assessing Fallopian tubal patency includes introducing a distension medium into a patient's uterus, introducing a contrasting medium into the uterus, and observing the contrasting medium, for example, via a hysteroscope, to determine whether the contrasting medium flows into one or both Fallopian tubes. A device for assessing Fallopian tubal patency includes a chamber for receiving contrast media, a flow path through the chamber for delivering distension media to a patient's uterus, and a flow controller for regulating the flow of distension media to the patient's uterus. The flow path is configured to permit flow of contrast media from the chamber into the flow path.

    摘要: Techniques for determining one or more fluid flow characteristic values of a structure are disclosed. A fluid flow vector and a pressure gradient vector for a portion of the structure are determined, and a dot/cross product of the fluid flow vector with the pressure gradient vector is obtained to provide a fluid flow characteristic value. The fluid flow characteristic value can be used for modifying the structure to improve fluid flow through the structure.

    摘要: A circuit arrangement having a plurality of variable capacitance elements such as varactors is described, the varactors having associated electronic control means which controls the capacitance of the variable capacitance elements over a control range. The control range is such that for any particular variable capacitance element a complete variation from a lowest to a highest capacitance is obtained from only a portion of the control range.

    摘要: An apparatus measures the flow rate of a fluid. The apparatus comprises a fluidic oscillator provided with an elongate slot in a direction Oz and suitable for forming a jet of fluid that oscillates in a plane Oxy perpendicular to the Oz direction, and an obstacle located upstream from the slot to modify the distribution of speeds in the flow. The obstacle is in the flow at least in the central portion thereof and is implemented in the form of a substantially plane plate.

    摘要: A first contact has an end portion which engages a second contact in a contacts closed position of the switchgear and which moves transversely across a pole face of a field coil and inwardly of an axis of the latter during movement of the contacts to an open position. The field coil is electrically connected in series with an arcing electrode and to which the second contact is also connected. Upon movement of the contacts from their closed position to their open position, an arc is drawn between the end portion of the first contact and a portion of the second contact. Further movement of the contacts towards their open position causes the arc to transfer its root from the second contact portion to the arcing electrode so that an arcing current then flows through the field coil to generate a magnetic field which causes the arc to rotate and become extinguished. Extinction of the arc is assisted by an electrically insulating fluid surrounding the switchgear. A principal arcing zone is defined by rotation of the arc, and the arc is disposed in this zone when it transfers its root from the second contact to the arcing electrode so that it can rotate immediately under the influence of the magnetic field.
