Abstract: A knowledge model of CAD knowledge may be created using a modeling language such as SysML to improve maintainability and re-usability of knowledge, thereby reducing workload. The SysML knowledge model may be stored in a knowledge repository coupled to a knowledge server. The SysML knowledge model may be accessed through the knowledge server. The SysML knowledge model may be associated with elements of a CAD model, and one or more elements of the CAD model may be linked to one or more corresponding elements in the knowledge model. Thus, when a value of one or more elements is changed in the knowledge model, the results of the change are updated substantially immediately in both the CAD model and the knowledge model and other applications using the knowledge model.

Abstract: A selector lever apparatus for a vehicle having an automatic transmission includes a selector lever shiftable to a plurality of mode setting positions including a parking position, and a selector lever lock mechanism. The lock mechanism locks the selector lever to prevent shifting of the lever when the lever is set at the parking position and a brake pedal is not depressed. When the brake pedal is depressed, the lock mechanism releases the locked state of the selector lever.

Abstract: The present invention includes a method of air-conditioning which forms, in a space to be air-conditioned, a plurality of circulating flows of air respectively blown through air outlets of an air-conditioning system disposed at predetermined positions within this space and which successively repeats two steps: a first step of changing the effective range of at least one of the circulating flows; and a second step of returning that circulating flow or flows as effected in the first step to the effective range thereof which obtained before the first step, and an air-conditioning system for carrying out this method, which forms, in a space to be air-conditioned, a plurality of circulating flows of air respectively blown through air outlets of an air-conditioning system disposed at predetermined positions within the space and which comprises: a means for changing the effective range of at least one of the circulating flows and returning that circulating flow or flows as changed to the effective range thereof whic
