Abstract: Methods and systems are provided for delivering food. In one embodiment, a method includes: receiving, by a processor, a food delivery request; autonomously preparing food, by the processor and at least one robot or task specific device, based on the food delivery request in a compartment configured to be sterile of an autonomous vehicle; and autonomously delivering the prepared food by the autonomous vehicle.

Abstract: A fluid energy reducing device includes a body having multiple, oppositely directed flow restrictors extending away from opposite sides of the body. Each flow restrictor can have a geometric shape such as a pyramid, triangle, or a conical shape. Fluid such as a fuel traveling in a wave entering the flow restrictors accelerates as the flow area in a flow passage of the flow restrictors decreases. The work performed by accelerating the fluid flow through one or more apertures created in each flow restrictor reduces the energy of the wave, thereby reducing noise in the fluid tank having the fluid energy reducing device when the reduced size and velocity wave subsequently strikes tank structure or walls.
