Abstract: A method for producing a gas discharge light source for emitting an electromagnetic radiation comprising a gas discharge tube filled with at least one discharge gas material and having a means for generating a gas discharge includes the following method steps: igniting the gas discharge tube filled with the discharge gas material, performing a forming operation in which the electrical operating power of the gas discharge light source is at least as high as the desired continuous operation power, the gas discharge tube is held at a temperature which is at least as high as the subsequent operating temperature, the intensity of the emitted electromagnetic radiation in the region of the desired wavelengths is monitored and the partial pressure of the vaporized discharge gas material is varied until the intensity of the selected electromagnetic radiation has reached a maximum value, whereupon a reservoir with excess discharge gas material is separated from the gas discharge tube in such a manner that the gas discharge tube under operating conditions does not contain any condensed discharge gas material. A gas discharge tube having a discharge material forming a discharge gas under operating conditions is distinguished in that the discharge gas material is incorporated in the inner wall of the gas discharge tube and there is no longer any condensed discharge gas material in the gas discharge tube.

Abstract: A vehicle automatic transmission control system in which based on the determined operating parameters of the vehicle including degree of throttle opening, vehicle speed or the like, a plurality of sets of membership functions of the parameters are established in accordance with a plurality of sets of predetermined fuzzy production rules. Fuzzy reasoning is carried out on the sets of the rules to determine a target gear ratio to shift to. The plural sets of the rules are predetermined hierarchically. One category of rules is directed toward the entire area of shift control, whereas another category of rules is directed toward a specific shift control area such as hill climbing. Further an additional category of rules is provided to presume the driver's intentional condition such as an intention to decelerate. Based on the last category of rules, fuzzy reasoning is carried out to determine the intentional condition. The condition thus obtained is added to the first-mentioned parameters and the second fuzzy reasoning is carried out to determine the target gear ratio on the basis of the first and second category of rules.

Abstract: The acceptability of the appearance of objects (12) such as consumer products is determined by forming an initial discriminant function (F) as a composite of a relatively small number of images (I) which are known to be acceptable. This initial discriminant function is then used to gather statistical information (P, A, B, C) about how a first relatively large number of images compare to the initial discriminant function. Thereafter, this statistical information is used (318-324) to select or aid in the selection of acceptable images from a second relatively large number of images, and the images selected as acceptable are used (334) to refine the discriminant function. The refined discriminant function is then used (e.g., during actual product inspection (402-414)) to determine which objects have an acceptable appearance and which do not.

Filed: 1993-03-02
Abstract: An improved adaptive pressure control which accounts for nonlinearity in the relationship between fluid pressure and shift time. To account for nonlinearity in the relationship between cumulative shift time error and corrective pressure, the control utilizes an empirically derived table of shift time vs. controlled pressure to develop a raw pressure error in lieu of a shift time error. The adaptive pressure correction, in turn, is developed in relation to the cumulative pressure error. This removes the effect of system nonlinearity from the adaptive control, allowing more accurate adaptive convergence than was heretofore achieved.
