Abstract: There is described a fire-fighting apparatus comprising a housing comprising an upstream air inlet and a downstream fire-extinguishing stream outlet and a hollow body therebetween, wherein the housing houses an air stream traveling at high velocity; and a spray assembly concentrically mounted to the housing. The spray assembly comprises a fluid inlet connected to a source of fluid outside the housing; and a plurality of injecting assemblies fluidly connected to the fluid inlet and designed for breaking down an inflow of the fluid into droplets and projecting the droplets of the fluid within the air stream in a multiphase fire-extinguishing stream. The injecting assemblies each comprises a fluid outlet; a base plate through which extends the fluid outlet; a holding structure mounted to the base plate and extending downstream therefrom, and a unibody jet-fragmenting device mounted to the holding structure facing the stream of fluid exiting the fluid outlet.

Abstract: A personal watercraft, driving control system, and method for controlling the watercraft. The watercraft includes a jet powered propulsion system; a steering system including a handle; and the driving control system including an electrically actuated device coupled to the steering system for applying torque to the steering system; at least one sensor positioned adjacent the steering system; and a controller. The controller is configured to: determine whether user torque is being applied to the steering system; and responsive to determining that the user torque is not being applied: determine a steering angle; determine a target angle for returning the steering system to a center position; compare the steering angle to the target angle; determine a centering torque; and operate the electrically actuated device to apply the centering torque to the steering, with the centering torque being applied only by the electrically actuated device.

Abstract: Systems, methods, and devices for enhancing steering control of a personal watercraft. An electrically actuated device is coupled to the steering system of the personal watercraft and applies torque to the steering system. At least one sensor is positioned adjacent the steering system and generates operational data of the personal watercraft. At least one controller is coupled to the electrically actuated device and the at least one sensor, and is configured to determine a first torque to apply to the steering system based on the operational data responsive to a second torque being applied to the steering system. The at least one controller is further configured to operate the electrically actuated device to apply the first torque to the steering system for providing enhanced steering control of the personal watercraft, with the first torque being applied only by the electrically actuated device.

Abstract: A method for controlling a power steering system utilizes a vehicle having a motor, a controller coupled to the motor, and a steering assembly. The method includes detecting a steering rate using the controller. A base level steering damping is computed using the steering rate. At least one approximate vehicle acceleration is determined. A steering torque of the steering assembly is sensed through a torque sensor configured to sense the steering torque of the steering assembly. Moreover, a user torque is determined using the torque sensor. A damping boost is computed using the user torque and the at least one approximate vehicle acceleration. A final steering damping gain is determined using the base level steering damping and the damping boost. The final steering damping gain is applied to the steering assembly to minimize unwanted feedback to the steering assembly.

Abstract: Systems, methods, and devices for enhancing steering control of a recreational vehicle. One or more mechanical dampers are coupled to and resist movement of a steering system of the recreational vehicle, and an electrically actuated device is coupled to the steering system for applying torque to the steering system.

Abstract: A poultry tray for shipping and displaying a dressed poultry. The poultry tray comprises a receptacle including a bottom wall and a peripheral wall having an upper end defining a receptacle opening. The poultry tray also comprises a flap pivotally connected to the receptacle at a rear end thereof. The flap is pivotable between an open configuration wherein the flap extends outwardly from the receptacle opening and a closed configuration wherein the flap covers a section of the receptacle opening and has a distal end detachably secured to the receptacle.
