First Claim
Patent Images
1. A fire fighting vehicle comprising:
- a turret rotationally coupled to the vehicle, the turret being configured to and dispense a fire-extinguishing agent;
a first gear immovably coupled to the vehicle;
a second gear coupled to the turret so that the second gear moves with the turret as the turret rotates relative to the vehicle, the second gear also being rotationally coupled to the first gear; and
a position sensor coupled to the second gear, the position sensor being used to determine the position of the turret based on the rotational motion of the second gear.

Abstract
A fire fighting vehicle includes a turret and a turret controller. The turret includes a base which is coupled to the vehicle, and the turret is configured to rotate relative to the vehicle at the base. The turret controller is configured to use feedback control to control the movement of the turret from a first position where the turret is positioned at a first angle of rotation at the base to a second position where the turret is positioned at a second angle of rotation at the base, where the first and second angles are different.

31. A vehicle comprising:
-
a turret rotationally coupled to the vehicle; a first gear which is immovably coupled to the vehicle; a second gear coupled to the turret, the second gear also being rotationally coupled to the first gear; a drive gear which is separate from the second gear and is coupled to the turret, the drive gear being rotationally coupled to the first gear so that rotating the drive gear causes the turret to rotate relative to the vehicle; and a position sensor coupled to the second gear, the position sensor being used to determine the position of the turret based on the rotational motion of the second gear. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
