Pressure-measuring apparatus is provided, including a battery and a pressure transducer. Also disclosed are methods for fabricating these devices. Further, a semiconductor package assembly having a semiconductor die and a windowframe capacitor is provided. Both the identification and organization steps allow the system to properly select a page based upon both page color and nodal locale. The third time base is associated with a constellation of satellites, and may be, for example, an absolute time associated with the constellation of satellites. The invention also relates to a process for oligomerizing light olefins using the silicon-based porous catalytic system, and to certain silicon-based porous catalytic systems.
