Claim 1
Independent Claim
198 words
A portable personal warning device adapted to detect smoke or power failure, comprising in combination: (a) a small portable housing; (b) a lamp and a reflector mounted to said housing and directed outwardly from one side thereof; (c) a smoke detector mounted in said housing and in communication with ambient air; (d) audible alarm means operatively connected to said smoke detector and responsive thereto; (e) a continuous power interruption detecting means mounted in said housing and connectable to available AC power; (f) DC power storage means mounted in said housing, including battery recharging means for recharging said DC power storage means; (g) circuit means connected to said lamp, said smoke detector, said audible alarm means, said power interruption detecting means and said DC power storage means; (h) control means connected to said circuit means for actuating said lamp and said audible alarm means in the event of an interruption of AC power or smoke detected by said detector; and (i) low and continuous DC power sensing means connected to said DC power storage means and to said circuit means and to said audible alarm means for actuating said audible alarm means in the event of low DC power.
