Abstract: A self-deploying rudder assembly for use with a water craft including an exhaust port having a exhaust stream includes a mounting assembly and a pivoting rudder blade assembly. The pivoting rudder blade assembly typically includes a thrust plate attached to one end of a rudder shaft and a rudder blade attached to the other end of the rudder shaft. When the selected thrust level is above the preselected thrust level, the thrust plate is moved out of the exhaust stream and the rudder blade is thereby moved from a deployed, operational position to a stored position.

Abstract: A water craft attached to a self-deploying rudder assembly for use with an exhaust port having a exhaust stream operating at a selected thrust level includes a mounting assembly and a pivoting rudder blade assembly. The mounting assembly typically includes a mounting ring for attachment to the exhaust port, along with a storage skeg. The pivoting rudder blade assembly typically includes a thrust plate attached to one end of a rudder shaft, with a rudder blade attached to the other end of the shaft. Some deployment means, such as a spring, is used to urge the thrust plate into the exhaust stream when the selected thrust level is below a preselected thrust level. However, when the selected thrust level is above the preselected thrust level, the thrust plate is moved out of the exhaust stream and the rudder blade is thereby moved from a deployed, operational position to a stored position within the skeg.

Abstract: An improved lipectomy device, or cannula, is disclosed having inner and outer tubes. The outer tube has an elongated aspiration aperture, and the inner tube has a spiral slot. A mechanism inside the handle of the device causes the inner tube to rotate, creating a traveling hole effect along the aspiration aperture. This obviates the necessity of the surgeon repeatedly pushing the cannula in and out.

Abstract: A pacifier is disclosed having a light emitting diode whereby the pacifier may be located in the dark. The pacifier is also equipped with an internal light bulb, activated by squeezing the handle, so that the pacifier may be used as a flashlight in order to position it properly in a baby's mouth.
