PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF THE INVENTION
[0001] The present disclosure relates to a fuel storage tank, and more particularly relates to a fuel storage tank with anti-slosh members for limiting an amount of fuel flow and attenuating a noise and force exerted on interior walls of the fuel storage tank.
BACKGROUND OF THE INVENTION
[0002] Fuel tanks may be utilized in vehicle systems for storing fuel to be used during combustion in an engine of the vehicle system. During vehicle operation, fuel may be displaced within the fuel tank due to changes in velocity of the vehicle, such as during cornering, braking, acceleration, and deceleration. When displaced, fuel may impact walls of the tank and generate noise. Noise produced by these impacts may be more apparent with hybrid vehicles, since they may operate with minimal interior noise when fuel combustion is deactivated. Tank sloshing mainly occurs and is received due to maneuvers like stop-and-go traffic or parking. Arising hybrid vehicles turn off the combustion engine during these operating conditions, so that no dominant combustion noise masks the slosh noises.
[0003] Many factors influence slosh noise performance, such as but not limited to an interior geometry of the tank shell, objects inside the tank which are impacted by moving fuel, structural behavior (material properties, stiffness) of the tank, fuel type, a fill level of the tank and vehicle motion. The slosh behavior can affect the stability and control of the vehicle especially when the vehicle fuel to gross weight ratio is high, such as in a spaceship or an airplane. In a smaller scale, such as in an automobile fuel tank, fuel slosh does not create significant stability and control problem since the fuel to gross weight ratio is relatively small. However, fuel slosh in an automobile fuel tank does propose another type of problem: the sloshing noise generated inside the tank.

[0004] Accordingly, there is a need of efficiently designed fuel tank that overcomes the above mentioned problem.
OBJECT OF THE INVENTION
[0005] The principal object of the embodiments herein is to provide a fuel storage tank with anti-slosh members pivotally mounted inside the fuel storage tank for limiting an amount of fuel flow. This dampen the turbulence created by incoming waves inside the fuel tank thereby reducing or eliminating the sloshing noise problem.
[0006] Another object of the embodiments herein is to provide a plurality of anti-slosh member each of which incudes baffle to limit incoming waves of fuel created inside the fuel storage tank due to movements of the vehicle thereby attenuating a noise and force exerted on interior walls of the fuel storage tank.
[0007] Another object of the embodiments herein is to harness kinetic forces from the incoming wave that rotates each of the anti-slosh member to generate electricity.
SUMMARY OF THE INVENTION
[0008] In one aspect object is satisfied by providing a fuel storage tank for a vehicle. The fuel storage tank includes a plurality of anti-slosh member each of which is pivotally mounted inside the fuel storage tank. Each of the anti-slosh member includes a baffle to limit incoming waves of fuel created inside the fuel storage tank due to movements of the vehicle thereby attenuating a noise and force exerted on interior walls of the fuel storage tank. Further, the kinetic forces from the incoming wave rotates each of the anti-slosh member to generate electricity.

[0009] In an embodiment, the rotations of each of the anti-slosh member generates the electricity using an energy harvesting mechanism.
[0010] In an embodiment, each of the anti-slosh member is in spherical shape.
[0011] In an embodiment, each of the anti-slosh member is a made of plastic material.
[0012] In an embodiment, one anti-slosh member is connected at a top end of the fuel storage tank and the anther anti-slosh member is connected at a bottom end of the fuel storage tank.
[0013] In one aspect object is satisfied by providing a method implemented by a lighting control system for controlling a light beam of a vehicle. The method includes producing the light beam in a first mode by a light source, measuring a status information of the light beam produced in the first mode using optical sensor, detecting a beam failure event associated with the light beam produced in the first mode based on the measured status information, and configuring the light source to produce a light beam in a second mode in response to detecting the beam failure event associated with the light beam produced in the first mode. Further, the method includes providing a notification about the production of the light beam in the second mode.

Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
[0020] The accompanying drawings are used to help easily understand various technical features and it should be understood that the embodiments presented herein are not limited by the accompanying drawings. As such, the present disclosure should be construed to extend to any alterations, equivalents and substitutes in addition to those which are particularly set out in the accompanying drawings. Although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are generally only used to distinguish one element from another.
[0021] Referring now to the drawings, and more particularly to FIGS. 1-3, there are shown preferred embodiments.
[0022] FIG. 1 illustrates a schematic representation of a fuel storage tank
(1) for a vehicle, according to embodiments as disclosed herein. The fuel storage
tank (1) includes anti-slosh members (2) each of which is pivotally mounted
inside the fuel storage tank (1) to harness the energy from the fuel.
[0023] In an embodiment, one of the anti-slosh members (2) is connected at a top end of the fuel storage tank (1) and other anti-slosh members (2) is connected at a bottom end of the fuel storage tank (1). These anti-slosh members
(2) mounted at both ends of the fuel storage tank (1) reduces the velocity of the
fuel when the fuel travels in a high velocity from one end to other end. They also
reduce the velocity of the fuel which is about to hit interior walls of the fuel
storage tank (1). Each of the anti-slosh members (2) comprises baffle to limit
incoming waves (3) of fuel created inside the fuel storage tank (1) due to

movements of the vehicle thereby attenuating a noise and force exerted on interior walls of the fuel storage tank (1).
[0024] Further, kinetic forces from the incoming wave rotates each of the anti-slosh member (2) to generate electricity. The rotations of each of the anti-slosh member (2) generates the electricity using an energy harvesting mechanism (4).
[0025] In an embodiment, each of the anti-slosh members (2) is in spherical shape such as a spherical ball or the like. In an embodiment, each of the anti-slosh members (2) is a made of plastic material or the like.
[0026] FIGS. 2a-2d illustrates a schematic representation of different types of the anti-slosh members (2) in the fuel tank (1), according to embodiments as disclosed herein.
[0027] The proposed invention is used to reduce or eliminate the sloshing noise problem by designing different shaped baffles as shown in the FIGS. 2a-2d and placing them at different positions in the fuel tank (1). Different designed and shaped baffles helps in keeping the fuel from sloshing around during maneuvering. Although some sloshing is impossible to avoid, but a reduction is extremely helpful in avoiding unwanted dynamics. The highest noise is generated only when the fuel hits the top of the tank. The baffle is designed in such a way that these noises are reduced. The height of the baffle should be sufficient enough to reduce the flow of fuel and hence uniquely designed baffles can be used as shown in the FIGS. 2a-2d.
[0028] Consider vehicle undergoes a sudden pitch-up into a climb, or a sudden acceleration when the afterburners are lit. Now the fuel will rush backwards, shifting the center of gravity backwards resulting in high kinetic energy with unpleasant noise. Sometimes, the fuel sloshing leads to vehicle

imbalance especially when the fuel to weight ratio is high. The baffles inside the fuel tank (1) absorbs the flow the fuel flow and also rotates due to the kinetic energy as shown at 5 in the FIG. 3. Further, the kinetic energy produced by the incoming waves (2) of the fuel produces the stress at the ends when reaching the ends of the tank. So the use of baffle reduced the noise and as well as the stress created at the ends.
[0029] FIG. 3 illustrates a schematic representation of rotation (5) of the anti-slosh members (2) in the fuel tank (1), according to embodiments as disclosed herein. The kinetic forces from the incoming wave rotates each of the anti-slosh member (2) to generate electricity. Further the rotations (5) of each of the anti-slosh member (2) generates the electricity using the energy harvesting mechanism (4).
[0030] The amount of noise being eliminated or electricity being produced depends upon the number of anti-slosh member (2) with the baffles, location of the baffle and its shape.
[0031] The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the embodiments as described herein.
