The present invention is directed to a minimally invasive system and method for monitoring changes in a cervix opening during labor, including changes in its diameter. The system having a probe and a monitoring unit serve to monitor periodically the cervix opening during labor and obtain measurements of the diameter of the cervix opening. The probe primarily includes a camera for imaging the cervix opening, a lens to provide an optimal field of view for the camera at close range to the cervix opening, a light source to illuminate the cervix and a balloon to expand the vagina around the probe and position the probe to allow unobstructed imaging of the cervix. The monitoring unit which controls the probe to acquire images of the cervix and receives and processes image data from the probe includes a processor which uses image segmentation techniques to identify and measure the opening of the cervix and generates data signals. The monitoring unit also includes an image display which displays information based on the data signals for viewing by health care providers and/or the patient, including graphic images of the cervix opening and other text information relating to the cervix opening as an indicator of the progress of labor. In one embodiment, the processor implements segmentation techniques and/or blob analysis algorithms to analyze the images of the cervix to identify the opening and measure its diameter. Other algorithms may also be implemented to correct for any spatial distortion, particularly barrel distortion.

A cap for use in priming a medical connector that has a distal end at which is disposed a distal connection tip with an aperture through which fluid may flow, and the connector having an internal valve. The cap has a reservoir device with an internal volume and a first opening at a proximal end that is connected with the aperture of the connection tip. The reservoir has a second opening at which is disposed an hydrophobic filter for allowing gases to vent to the atmosphere while retaining liquid in the reservoir device. Over the reservoir device is mounted a slidable housing device used to activate the internal valve of the connector to a flow configuration at which fluid flows from the connector into the reservoir device. The user monitors the reservoir device and when gas has been vented so that only liquid remains, the user slides the housing device to de-activate the connector to the non-flow configuration at which the connector draws back into itself the liquid stored in the reservoir. The cap is then disconnected from the connector with the connector being primed.

The invention relates to a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine. A fuel supply line enters an injector housing from a high pressure fuel source which can be hydraulically connected to a pressure chamber. A 3/2 directional control valve for injecting fuel into the combustion chamber has a valve piston which can be moved axially back and forth between a rest position and an injection position. The 3/2 directional control valve, by a first end face of the valve piston, which adjoins a hydraulic coupling chamber, is hydraulically coupled to and can be activated by a piezoelectric actuator. The 3/2 directional control has a ball element which is connected to a second end face of the valve piston and, in the rest position, can be moved against a first sealing edge and, in the injection position, can be moved against a second sealing edge.
