1. A fire extinguishing apparatus comprising:
- a turret mounted in a preselected area;
sensor means for detecting a fire;
nozzle means mounted on said turret, said nozzle means being arranged and constructed to eject a fire extinguishing agent; and
aiming means coupled to said sensor for aiming said nozzle means toward said fire when said fire is detected by said sensor means;
wherein said sensor means includes a first set of sensors having optical axes disposed at a first angle with respect to a vertical line and a second set of axis disposed at a second angle with respect to said vertical line.

Abstract
An automated fire extinguishing apparatus includes a turret with a nozzle connected to a water supply. A plurality of sensors are used to detect a fire monitored by the apparatus. The signals from the sensors are used to aim the nozzle toward the fire and to initiate water ejection therefrom. After the fire is extinguished the water is turned off.

19. A method for detecting a location of a fire within a predetermined area, said method comprising the acts of:
-
(a) monitoring infrared energy within the predetermined area;
(b) filtering out the infrared energy not within a predetermined frequency range to produce filtered energy signals;
(c) determining existence of a fire within the predetermined area based on the filtered energy signals;
(d) determining a location of the fire within the predetermined area when said determining (c) determines the existence of the fire; and
(e) directing a nozzle of a fire extinguishing apparatus to the location of the fire, wherein the location of the fire is an x-y location, and wherein said directing (e) directs the nozzle of the fire extinguishing apparatus to the x-y location of the fire by moving the fire extinguishing apparatus in both an x-direction and a y-direction. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)

28. A method for detecting a fire within a predetermined area, comprising:
-
(a) sensing infrared energy within the predetermined area;
(b) converting the infrared energy into electrical signals;
(c) filtering the electrical signals to produce filtered electrical signals which correspond to a fire;
(d) detecting the presence of a fire within the predetermined area based on the filtered electrical signals; and
(e) moving a fire extinguishing nozzle so as to point to the fire detected in said detecting (d), wherein said detecting (d) detects a location of the fire, and wherein the location of the fire is an x-y location, and wherein said moving (e) moves the fire extinguishing nozzle to the x-y location of the fire by moving the fire extinguishing apparatus in both an x-direction and a y-direction. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A system, comprising:
-
a fire detector that detects a location of a fire within a predetermined area, said fire detector monitors infrared energy within the predetermined area, filters out the infrared energy not within a predetermined frequency range to produce filtered energy signals, determines existence of a fire within the predetermined area based on the filtered energy signals, and determines a location of the fire within the predetermined area when the existence of the fire has been determined; and
a fire extinguishing agent that supplies fire extinguishing agent toward the location of the fire when the existence of the fire has been determined and ceases supply of the fire extinguishing agent toward the location of the fire when the existence of the fire is no longer detected.
