Abstract: A side view mirror assembly for an automobile comprises a side view mirror having a reflective surface and a transparent portion, a target fixed with respect to the automobile, located behind the side view mirror, and an auxiliary mirror having a reflective surface which is considerably smaller than the reflective surface of the side view mirror attached to the rear of the side view mirror, and so inclined with respect to the side view mirror that it enables a driver of an automobile to see the target in the auxiliary mirror through the transparent portion of the side view mirror, and when the target is seen by the driver in the auxiliary mirror the line of sight of the driver looking in the side view mirror is directed toward a required blind spot area near the automobile.

Abstract: A device for adjusting a side view mirror of an automobile has an auxiliary mirror arranged on the side view mirror and having a reflective surface inclined relative to the reflective surface of the side view mirror so that when the driver sees an image of a target on the automobile body in the auxiliary mirror the line of sight of a driver looking in the side view mirror is directed toward a required blind spot area near the automobile.

Abstract: A method and apparatus for measuring of concentrations of components of a fluid mixture. One side of a membrane permeable to the component to be determined is contacted with a sample of the fluid mixture to be analyzed. The second side of the membrane is contacted with a test fluid passing the membrane at different speeds. The resultant properties of the test fluid are determined for the different speeds of flow past the membrane and the measured values allow to determine the concentration or partial pressure of the component in the fluid mixture. The fluid mixture is preferably blood and the components can be oxygen and carbon dioxide. Preferably the membrane provides a spiral path for the test fluid in order to allow employing a more rapid flow of the test fluid past the membrane. Furthermore, such a configuration can be combined with a catheter for hemodynamic blood pressure measurement thereby providing a single probe for continuous monitoring of blood in clinical practice.
