Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
151 words
A wrist watch, comprising: a timing unit having an electric powered time piece circuit capable of providing time information and provided with switches for pre-setting alarm time and being capable of producing an electric pulse at the moment of a pre-set alarm time, and a display unit for showing the time information supplied by said time piece circuit; an alarm unit having: a memory unit adapted to receive and convert said electric pulse into a steady electric output; a switching unit operable by said steady electric output produced by said memory unit to allow electric power to be supplied therethrough; a signal generator capable of transforming an electric power supplied thereto through said switching unit into an intermittent, alternating voltage capable of stimulating people; and a pair of electrodes to which said intermittent, alternating voltage is supplied, said pair of electrodes being exposed through the back side of the alarm watch.
