Circuits, methods, and apparatus that prevent detection and erasure of a configuration bitstream or other data for an FPGA or other device. The present invention relates to a genetically modified microorganism of Clostridium saccharoperbutylacetonicum, and a method for producing butanol using the microorganism. The second electrode pattern is made of the same metal as the first electrode pattern and overlaps the edge of the amorphous silicon pattern at an opposite side of the first electrode pattern. The locking mechanism may also comprise at least one aperture in the base of the substantially rectangular retaining mechanism, and at least one stake mechanism, wherein the stake mechanism is driven through the aperture and into a work surface. The monitoring device is preferably located at a low flex area of the tire to help avoid the problem of the innerliner flexing.
