Abstract: A control device may include a processor may include a core, a timer peripheral, and a peripheral direct memory access controller. The processor may include a receive port coupled to a communication port of the reporting device via a communication line. The control device may include a timer peripheral that can generate an enable signal and a timing signal, and a buffer circuit that may include an enable port for the enable signal for enabling/disabling the buffer circuit, an input port for the timing signal, and an output port coupled to the communication line. The processor may enable/disable the buffer circuit to control the timing of data bit(s) transmission across the communication line by the reporting device. The peripheral direct memory access controller may store the data bit(s) in a receive buffer during the bit period, and the core may subsequently retrieve the data bit(s) from the receiver buffer.

Abstract: A toxic material detection apparatus includes a sample collection portion including a sample inlet and a sample concentrator adapted to concentrate an environmental sample on a substrate. A sample distributing system transfers portions of the substrate to a color sensor and an ion mobility spectrometer for simultaneously analysis and toxin detection, particularly cholinesterase inhibitor detection. Optionally, a portion of the substrate may be directed to an archive for possible analysis at a later time. Reagents utilized include the enzyme acetylcholinesterase (AChE), and the reactants acetylthiocholine iodide (ATCI) and 5,5?-dithio-bis-(2-nitrobenzoic acid) (DTB). A data management unit provides for near-real-time analysis of the samples in under 5 minutes. Simultaneous “hits” by both analysis methods indicate the presence of a cholinesterase inhibitor.
