An LED illumination device is configured to receive coded messages by at least one of radio signals in free space, electrically conducted signals by wire, and light wave propagated signals in free space, process the coded messages, and transmit the coded messages by two or more of radio signals in free space, electrically conducted signals by wire, and light wave propagated signals in free space. The system also includes a modular cooling unit having a housing for receipt in the rack, a ram air inlet and outlet, and a refrigerant inlet and outlet. The capacitor includes a source or drain electrode and a gate insulating layer of the second transistor and a capacitor electrode over an insulating layer which covers the second transistor. In particular, significant increases in ballistic performance can be achieved versus a non-diamond-containing composite, particularly versus the M993 threat. Aquatic facilities susceptible to accumulation of organic N-chloramines, cyanuric acid and other oxidation resistant compounds, as well as oxidation resistant parasitic organisms such as cryptosporidium and Giardia, obtain dramatic improvements in the rate of oxidation and subsequent inactivation of these undesirable contaminants.
