Abstract: A robust method of page indication (PI) detection improves the probability of detecting a transmitted PI under conditions that decrease the probability of accurate PI detection. The method includes choosing a standard value of a PI threshold against which to compare accumulated PI bits when the probability of correctly detecting the PI is high, and choosing a derived value of the PI threshold lower than the standard value when the probability of correctly detecting the PI is low. The derived PI threshold value determination includes a factor indicative of a desired probability of accurate PI detection.

Abstract: A tool includes a tool body and a cutting portion detachably mounted thereon, the tool being rotatable about a longitudinal center axis. The tool body includes flutes formed in an outer surface thereof, and a pair of forward projections at a front end thereof. The cutting portion includes front flutes formed in an external side thereof, and a pair of recesses extending circumferentially in communication with respective ones of the front flutes. To connect the cutting portion to the tool body, the cutting portion and tool body are converged longitudinally so that the projections enter the front flutes. Then, relative rotation is produced between the cutting portion and tool body to align the front flutes with the rear flutes while causing the projections to enter the recesses and form therewith a bayonet coupling.
