A system to detect and identify various aerosol agents, such as biological agents which have been aerosolized, is disclosed. The micromirror array assembly includes a plurality of mirrors monolithically formed with a frame, attached by way of hinges and gimbal portions. In addition, the method includes determining that the second guest kernel page does not correspond to the entry in the soft whitelist, and denying an execution of the second guest kernel page if the second guest kernel page does not correspond to the entry in the soft whitelist. A device according to the technique may include chip-internal non-volatile memory to store the certificate along with the private key, in the manufacturing process. The workpiece also comprises an electrically conducting layer, arranged on the at least two semiconductor chips, the electrically conducting layer being arranged at least on regions of the second main surface, and a molding compound, arranged on the electrically conducting layer. An assembly for clamping the workpiece against a fence member on the base consists of a lug that is engageable at each of numerous locations along the length of a channel for location proximate the fence, and a clamping piece that is rotatably mounted on the lug piece for being turned into clamping engagement with the workpiece.
