2119235 9306571 PCTABS00021 A dog-bone-shaped personal safety device (101) has a cylindrical central section (104) with grips (136, 137) for activating the device. If a minimum pressure is applied for a minimum time to the grips (136, 137), an alarm sound is produced by issuing first and second different sinusoidal components from respective first and second speakers mounted in opposite ends (102, 103) of the device. The resulting sound is much more annoying at short distances from the device than farther away, encouraging an assailant to move away. A recessed button (132) is manipulated in combination with the grips (136, 137) to control the device via a microprocessor.
