A logic gate is constructed of an insulated gate field effect transistor having a thin gate insulation film. The system further comprises a standby mode control circuit to control the state of the master and slave flip flops during active and standby mode operation based on at least two control signals. In one embodiment, a braking mechanism using two small rollers biased against the bigger roller or wheel is used. The base includes arcuate channels sized for receipt of sight pins and arched to ensure that the sight pins are aimed at the archer’s eye regardless of vertical spacing. An e-mail message rate is determined and compared with an e-mail message rate threshold. The coating includes polymeric coating particles which advantageously may be in the form of a micro-fine powder.
