A reinforced carton handle structure includes a carton wall panel hinged along a first fold line to a linear series of at least two reinforcing panels hinged one to the next. For instance, the inner fixed structure and the outer sleeve may move independently with respect to each other. A Si1xGex layer is also disposed between the electrically insulating layer and the unstrained silicon active layer. IO access to the second storage device is minimized by retaining at least a portion of the first check data and at least a portion of the additional check data in a readily accessible storage medium, during servicing of a first IO request. The controller 24 in response to the navigation signal adjusts the speed of the vehicle 22. This may be done, for example, by ensuring that a gap between a substrate and a substrate table is filled with immersion liquid or by causing a localized flow radially outwardly from the optical axis in the vicinity of the edge of the substrate.
