Abstract: A fire fighting vehicle includes a powertrain including an engine, a battery pack, and an electromechanical transmission; a power divider; and a controller. The power divider is positioned between the engine, the pump, and the electromechanical transmission. The controller is configured to monitor a state-of-charge of the battery pack and operate the engine, the power divider, and the electromechanical transmission such that the state-of-charge is maintained above a minimum state-of-charge threshold that is sufficient to facilitate (i) accelerating the fire fighting vehicle to a driving speed of at least 50 miles-per-hour in an acceleration time and (ii) maintaining or exceeding the driving speed for a period of time. An aggregate of the acceleration time and the period of time is at least three minutes.

The accessory module is configured to receive mechanical energy and provide at least one of electrical energy or fluid energy. The electric motor is configured to drive (a) the pump to provide fluid to the discharge such that the fluid is expelled from the discharge and (b) the accessory module to provide the at least one of electrical energy or fluid energy.

Abstract: A fire fighting vehicle includes a powertrain, an accessory drive, and a controller. The powertrain includes an engine, an energy storage device, and an electromechanical transmission (i) electrically coupled to the energy storage device and (ii) selectively mechanically coupled to the engine.

Abstract: Techniques for service policies for communication sessions are described. According to various embodiments, a service policy specifies various rules and/or procedures for handling communication sessions. For instance, a service policy can specify service priority designations to be applied to communication sessions based on various attributes of the communication sessions. Techniques discussed herein provide for automated and dynamic management of service policies in a variety of communication scenarios, e.g., via per-session customization of service policies. In at least some embodiments, techniques may be employed to remedy problems that may occur during a communication session, such as via bandwidth reallocation, dynamic remapping of routing paths, and so forth.

Abstract: Embodiments are directed towards managing application delivery over a network. Change information that corresponds to changes to an application may be provided to a delivery pipeline. The change information may be verified in part based on a static analysis of the content of the change information, compiling, and unit testing. Reviewers may be notified to approve the change information. A version of the application that includes the change information may be generated. Acceptance testing may be performed that includes provisioning computing resources in an acceptance computing environment. And, deploying a version of application that includes the change information into the acceptance computing environment. If the acceptance testing passes, a shipping operation may be enabled pausing the delivery pipeline until an authorized user activates the shipping operation restarting the delivery pipeline and deploying the application to one or more computing environments.
