  It has been determined that vibrational silent low the user to select particular on and off (tactile) alert devices are more effective if they are provide for a wide range turned on intermittently, or "pulsed? This has been
proven repeatedly in subjective evaluations to determine
silent alert device performance. An interesting result invention is to use the of the testing showed that most users had differing
preferences for the cadence formats. For this reason,
a user-selectable cadence format was required to
maximize product appeal. "on" intervals and blank spaces ( - ) representing "ofp example, each interval could last l/l6 of a This invention makes possible the selection of more could set up to 16 intervals for a total than one tactile alert cadence format.

Obviously, the greater the quantity of intervals per repeated patter...
