  • Patent number: 12023534
    Abstract: A method includes acquiring fluid level data indicating a fluid level within a fluid tank of a respective fire apparatus, acquiring fault data indicating any active faults with components of the respective fire apparatus, acquiring maintenance data indicating whether maintenance is due or overdue for the respective fire apparatus, acquiring exercise data indicating an elapsed time since the respective fire apparatus was last exercised, determining an overall readiness score for the respective fire apparatus based on the fluid level data, the fault data, the maintenance data, and the exercise data, and generating a graphical user interface including (i) a readiness factor section listing a plurality of readiness factors having an associated status or value based on the fluid level data, the fault data, the maintenance data, and the exercise data and (ii) a readiness score section providing a background indicator and the overall readiness score displayed over the background indicator.

  • Patent number: 11617908
    Abstract: A fire apparatus includes an engine, a fluid delivery system, and a controller. The fluid delivery system includes a first pump that provides a first fluid output at a first pressure, and a second pump positioned downstream of and coupled to the first pump in a serial arrangement. The second pump is driven by the engine. The second pump provides a second fluid output at a second pressure. During a first mode, the first fluid output is dischargeable from a low pressure discharge. During a second mode, the second fluid output is dischargeable from a first high pressure discharge and/or a second high pressure discharge, the engine operates at a first set point when the second fluid output is discharged from the first high pressure discharge, and the engine operates at a second set point when the second fluid output is discharged from the second high pressure discharge.

  • Patent number: 11324981
    Abstract: A readiness monitoring system for a fire apparatus includes a processing circuit that has programmed instructions to acquire fluid level data indicating at least one of a water level within a water tank, a fire suppressing agent level within an agent tank, a fuel level within a fuel tank, or a diesel exhaust fluid level within a diesel exhaust fluid reservoir of the fire apparatus; acquire fault data indicating any active faults with components of the fire apparatus; acquire maintenance data indicating whether maintenance is due or overdue; acquire exercise data indicating an elapsed time since the fire apparatus was last exercised; and determine a readiness score for the fire apparatus based on the fluid level data, the fault data, the maintenance data, and the exercise data.

  • Patent number: 10843017
    Abstract: A fire fighting vehicle includes a chassis, an engine coupled to the chassis, a fluid tank configured to store a fluid, a fluid delivery system, and a controller. The fluid delivery system includes a first pump, a second pump, a low pressure discharge, a first high pressure discharge, and a second high pressure discharge. The first pump is coupled to the fluid tank and configured to pump the fluid therefrom at a first pressure. The second pump is positioned downstream of and coupled to the first pump in a serial arrangement. The controller is configured to selectively vary at least one of a speed, a power output, and a torque output of the engine and thereby provide the fluid to at least one of the first high pressure discharge and the second high pressure discharge at a target discharge pressure.
