A safety helmet system for motorcycle and bicycle riders includes a lightweight impact resistant helmet having an onoff switch. The circuitry employs an antifuse scheme that includes an array of memory bitcells, each containing a program device and an antifuse element configured with current path isolation well and for storing the memory cell state. The numeric keyboard includes a third connector formed on a first side surface and a fourth connector form on a second side surface. A handle mechanism is pivotally attached to a second end of the first linkage element and to the second end of the second linkage element. An imprint material including: a specific acrylamide such as N,N\u2032-dimethylacrylamide; a compound having alkylene oxide units and having 2 to 6 polymerizable groups at the ends of the compound, in which the alkylene oxide units are ethylene oxide units, propylene oxide units, or a combination thereof; and a photopolymerization initiator. The tool is released from the docking station and descends the well.
