Abstract
Abstract A safety cane incorporates an ambient light sensitive illumination device for conserving battery power. A tipping detector is also incorporated which sounds an audible alarm after a first time delay. If the cane is not retrieved by the end of the second time delay, the cane broadcasts an initiating instruction to a telephone dialing device.
