The inorganic component inhibits deprotonation of the organic conducting component when the composite is exposed to a medium having a pH which would deprotonate the organic conducting component but for the presence of the inorganic component.

Abstract: The present invention performs a digital computation with a lower than worst-case-required clock period (i.e., a faster clock), and at the same time performs the same computation with a larger, worst-case-assumed, clock period (i.e., a slower clock) on a second system with identical hardware. The outputs from the computations are compared to determine if an error has occurred. If there is a difference in the two answers, the faster computation must be in error (i.e., a miscalculation has occurred), and the system uses the answer from the slower system. In one embodiment, the present invention utilizes two copies of the slower system that each run half as fast as the main system. However, the two copies produce results in the aggregate at the same rate as the main system, which is running at a much faster rate than possible without the invention. Hence the present invention improves performance (e.g., speed), albeit with more hardware.

Abstract: A system for the detection of bacteria based on bacteria-antibody complexes. Bacteria attached to antibody are detected with resonance Raman spectroscopy. The bacteria are detected directly in a great numerical excess, e.g. 100 to 10,000 of antibody molecules. A sample to be tested is placed in a medium, the medium containing antibodies attached to a surface for binding to a specific bacteria to form an antigen to antibody complex. The medium is contacted with a beam of light energy. The bacteria, as a lower resonance enhanced Raman backscattered energy, is analyzed for the presence or absence of the bacteria.

Abstract: A pneumatic demultiplexer that allows a person with a disability to control multiple assistive technology devices by the use of a single sip-and-puff tube. The devices to be controlled are operated by a single pneumatic or electrical switch input. The pneumatic demultiplexer is under the control of a microprocessor. In a scan stage the user selects the target device via scrolling LED indicators. When a specific device is chosen, the corresponding solenoid valve is activated to connect the input sip-and-puff port to the pneumatic output port. In the activation stage, the input sip-and-puff tube controls the target device directly via the pneumatic demultiplexer. The microprocessor monitors the line activity via a sip-or-puff switch. A watchdog timer is implemented by the microprocessor. After there is a lack of activity for preprogrammed time period, the system switches from the activation stage back to the scan stage.
