Embodiments of the invention are directed to systems, methods and computer program products for targeting offers to customers. The transparent elastomeric compositions can be covulcanized with rubbers such as polybutadiene, polyisoprene, styrene-butadiene rubber, styrene-isoprene-butadiene rubber, isoprene-butadiene rubber, ethylene-propylene diene rubber or natural rubber. In such diamond film, the electron emission voltage is significantly reduced. A demand model is created based on Bayesian modeling. The electrical leads include slack loops disposed in the rotating assembly which permit rotation of the jaw members about the axis.
