## Background
FIELD OF THE INVENTION
The present invention relates generally to the field of vehicle performance parts. More specifically, the present invention relates to apparatus and system to measure the air velocity through a vehicle air filter.
BACKGROUND OF THE INVENTION
Most commercial and private vehicles have a plethora of parts and necessary elements to make them run properly. A typical vehicle has thousands of moving, functional and essential parts.
For many car enthusiasts, modifying a factory vehicle with upgraded aftermarket parts is rewarding and satisfying in a multiplicity of different ways. Many individuals decide to modify their vehicles for aesthetic purposes. However, many individuals modify or alter their vehicles to elicit better performance from their vehicle or to upgrade from more restrictive parts that come with their vehicle from the factory to less restrictive parts with better usability and/or performance.
There are some very common aftermarket modifications that most vehicle enthusiasts, such as car owners, motorcycle owners, boat, and other gasoline/diesel powered vehicle owners choose to employ. A few of these common aftermarket modifications are replacement of a vehicle exhaust system, and replacement of headers (which are tubes that run from the engine and direct unwanted heat and exhaust away from the engine). Additionally, many individuals will recalibrate a vehicle's computer which regulates engine speed and other functions, to elicit higher performance and tolerances. However, the most common type of vehicle modification is the replacement of the stock air filter with an aftermarket type air filter.
The two main types of air filters that are used in vehicles are the combustion air filter, and the cabin air filter. The cabin air filter is a pleated paper filter that is placed in the outside-air intake for the vehicle's passenger compartment. Some of these filters are rectangular and similar in shape to the combustion air filter. Others are uniquely shaped to fit the available space of a particular vehicle's outside-air intakes. This type of filter is relatively new to the car industry and often gets clogged and dirty. Newer cabin air filters may reduce allergens and may utilize additional compositions to reduce particulates, odors and the like.
The combustion air filters are used in vehicles to prevent abrasive particulate matter from entering the engine. If particulate is allowed to enter the engine, it could cause mechanical problems or contamination of vital fluids needed for proper engine management, including contamination of engine oil.
Most modern, fuel injected vehicles use some sort of pleated paper filter element in the form of a flat panel. This filter is usually placed inside a plastic box connected to the throttle body with a large hose. The filter may stop particulate matter and other contaminates from entering the engine and causing damage or degradation of the engine.
Older vehicles typically are not fuel injected, but rather use carburetors or throttle body fuel injection. These types of vehicles typically use a different air filter, usually only a few inches high and cylindrical in shape. These air filters are positioned above the carburetor or throttle body, usually in a metal or plastic container which may incorporate ducting to provide cooler and/or warmer inlet air, and are secured with a metal or plastic lid.
Most air filters are constructed from similar materials. Traditional prior art air filters are constructed from a pleated paper filter because they are efficient, easy to use and cost-effective. Other air filters are constructed of different materials such as cotton, foam and the like. Aftermarket filters are typically constructed of one and/or a combination of these materials and may allow for more air flow from the outside of the vehicle to the engine, which may increase engine performance while still reducing contaminant intrusion into the engine.
A very large aftermarket presence has arisen from the replacement of the stock factory air filter with a newer, more efficient filter that may allow for increased air flow through the filter and subsequently into the engine. However, many of these aftermarket manufacturers claim that their air filter performs better than another manufacturer's aftermarket air filter, when in fact they may not, or in the alternative, may perform more poorly.
One problem that exists, is that the air flow through an air filter may positively affect performance, but it is difficult to detect from normal use of the vehicle any changes that an aftermarket filter may provide. Additionally, another problem that exists, is that there is no good method or technique to determine which air filter product may be better than a competing air filter product at reducing air restriction through a filter media.
A need therefore exists for an improved apparatus and system to determine the air flow and air restriction through a vehicle air filter. Additionally, a need therefore exists for an improved apparatus and system that may be utilized to determine the air flow through a filter and a system for measuring exiting air velocity from an air filter.
A need also exists for an improved apparatus and system to determine the air flow through a plurality of competing and different vehicle air filters and a system for measuring the air flow through the plurality of air filters. Moreover, a need exists for a system that may compare the air flow through a plurality of different air filters to determine which air filter provides the greatest amount of air flow and the least amount of air restriction through the filters. Lastly, a need exists for a system and apparatus to display the results of the air velocity testing to a viewer.

DETAILED DESCRIPTION
Turning now to the drawings wherein elements are identified by numbers and like elements are identified by like numbers throughout the 5 figures, the invention is depicted in FIG. 1 and illustrates an air velocity apparatus 1 that may be utilized to illustrate air flow through an air filtration media 3.
Referring first to FIG. 1, an air velocity apparatus 1 is provided. The air velocity apparatus (hereinafter referred to as a device) may have a plurality of different configurations, but for illustrative purposes is shown in only a single embodiment for ease of description. Thereby, the device 1 may have a first side 5 and a second side 7. Additionally, the device 1 may have a front portion 13 and a rear portion 11. Moreover, the device 1 may further have a top portion 9 and a bottom portion 15. The device may also have wheels 19 attached to the bottom portion 15 of the device 1 for movement and relocation of the device 1 when desired for illustrative purposes. The wheels 19 may allow the device 1 to be moved from one location to another where the device may be used, installed and utilized for illustration to a plurality of different viewers (not shown).
As further illustrated in FIG. 1, the air velocity apparatus 1 may a viewable portion 21 in the front portion 13 of the device 1. In an exemplary embodiment, this viewable portion 21 may be constructed of PlexiglassTM. However, it should be understood that the viewable portion 21 may be constructed of any suitable transparent material that would allow the viewer to view the inside portion 23 of the container 25. Therefore, the viewable portion 21 may be constructed of glass, plastic, or any other transparent material. The preferred embodiment contemplates having this viewable portion 21 located at the top 29 of the front portion 13. However, the viewable portion 21 may encompass the entirety of the front portion 13. It should also be understood that the viewable portion 21 may be contained on the first side 5 and on the second side 7, and/or may be positioned on the back portion 11 of the device for illustration of the air velocity apparatus to the viewer.
FIG. 1 further illustrates the top portion 9 of the air velocity device I whereby the top portion has a hinge 29 attached to the top portion 9 of the device 1 whereby the hinge 29 attaches the top plate 31 to the top portion 9 of the device 1. The hinged top plate 31 may be incorporated into the device 1 to allow for insertion of independent air filtration media 33 into the device. In an exemplary embodiment, the air filtration media 33 is an air filter 35. The air filter 35 may be placed into an opening 37 in the top portion 9 of the device that may be specifically designed and constructed to allow for insertion of an air filter 35 into the opening 37. The opening 37 may be designed to accommodate a specifically sized air filter 35 and/or may be designed and constructed to accommodate a plurality of differently sized air filter 35. As further illustrated in FIG. 1, a second air filter 41 may also be accommodated into a second opening 43 in the top portion 9 of the device, whereby a second filter 41 may be inserted into the second opening 43 which is adjacent to the first opening 37. As with the first opening 37, the second opening 43 may be designed to accommodate a specifically sized second air filter 41 and/or may be designed to accommodate a different sized air filter.
As can be seen from FIGS. 1 and 2, the device 1 may also have a third position 45, a fourth position 47, a fifth position 49 and a sixth position 51, whereby the third, fourth, fifth and sixth positions 45, 47,49 and 51 may have corresponding third, fourth, fifth and sixth openings 53, 55, 57 and 59, respectively, which may be adapted to accept a third, fourth, fifth and sixth air filter 61, 63, 65, and 67 respectively. Although in an exemplary embodiment, the present invention illustrates the use of six stations which may accommodate six air filters, the invention is not limited to this pre-set amount, and further is indicative of having exactly six stations to accommodate six air filters. The invention may be utilized for any number of air filters and can have substantially more or less than the illustrated six stations.
Additionally, FIG. 1 illustrates the blower 71 utilized to create air velocity through the air filter 37. As illustrated in FIG. 1, the blower 71 may be positioned at the bottom section 73 of the device 1. In an exemplary embodiment, the device 1 may use a first blower 71 and a second blower 75 whereby the two blowers 71, 75 may create the necessary air flow necessary to provide air velocity output through the air filter 37. This may be accomplished by providing a common plenum 77. The common plenum 77 may ensure that all of the filter 37 will be subject to the same differential pressure. The difference in filter restriction will cause any differences in air flow velocity through any respective filter 37.
FIG. 2 illustrates the air velocity device I in a disassembled state. As previously demonstrated, the device 1 may have a first side 5 and a second side 7 which is part of the frame 81 of the device. Additionally, the device 1 may have a front plate 83 and a rear plate 85 that may be removed from the frame 81 of the device 1.

FIG. 3 illustrates a top view of the air velocity device 1. The top portion 9 of the device 1 may have a top plate 31 attached to the outside edge 103 of the top portion 9. The top plate 31 may be hinged to the outside edge 103 by the use of a connection means 105. In an exemplary embodiment, the connection means 105 is a hinge 29. In an embodiment, the air velocity device may have a first hinge 29 and a second hinge 107. However, it should be understood that any type of other connection means 105 such as adhesive, hook and fastener, snap fit and the like may be utilized to attach the top plate 31 to the outside edge 103 of the top portion 9 of the device 1. The front position 109 of the top plate may have a handle 111 to allow for pivoting of the top plate 31 relative to the top portion 9 of the device 1. Underneath the top plate 31 is the accommodation portion 87 which has the plurality of openings thereon for accommodation of a plurality of air filter 35. As can be seen in FIG. 3, the accommodation portion 87 of the device 1 may also have a plurality of wind meters and/or anemometer 93 attached thereto. The wind meters extend away from an inside edge 113 of the accommodation portion 87 and extend into the space 112 occupied by the opening and/or the positioned air filter 35. In an exemplary embodiment, the wind meters may be securely mounted to the top plate 31 so the air velocity that is measured is always measured at the same place above the filter 37 in the plurality of positions. The air filter 35 may be fitted onto the accommodation portion 87 whereby the accommodation portion 87 may be fitted to specified parameters to accommodate a specified sized air filter 35. A plurality of different air filter 35 may be utilized as illustrated in FIG. 3 whereby the wind meters are positioned on a second side 113 of the air filter to determine the air restriction through the plurality of air filter 35 and display to the viewer which air filter 35 allows the least restriction of air through the filter 35.
It should also be noted, that the air filter 35 may be inserted and extracted from the accommodating portion 87 and re-inserted into another location on the accommodation portion 87 to illustrate that each location will have a substantially similar air flow velocity, whereby no matter where the air filter 35 is located on the accommodation portion 87, the air velocity through the air filter should remain substantially constant.
FIG. 4 illustrates the wind meters 93 associated with the accommodation portion 87 of the device 1. The wind meters 93 are located above the second side 113 of the air filter 35 whereby the unrestricted air flow through the filter 35 is analyzed by the wind meters 93. The wind meter 93 collects a sampling of the air flow through the filter 35 and displays the data collected to the viewer. In an exemplary embodiment, the wind meter may have a display means 115 whereby the user can easily determine how much air flow is allowed through the air filter 35. The display means 115 may be a LCD screen 117 that illustrates the air flow through the filter 35. In an exemplary embodiment, the wind meter analyzes and displays the air flow velocity in miles per hour. However, in another embodiment, the wind meter 93 may display the results of the air velocity through the air filter 35 in knots, kilometers per hour, or any other display of velocity pressure and/or airflow.
Additionally, the wind meter 93 may also have a first button 119 whereby the button may allow the viewer to view the results of the air restriction of each air filter 35 in a plurality of different capacities including miles per hour, kilometers per hour and the like. The wind meter may be adjusted to display the results based on the preference of the viewer. The wind meter may also have a second button 121 whereby the second button 121 may be utilized to reset the wind meter for further testing and demonstration of its corresponding air filter 35.
FIG. 5 illustrates the device I whereby a plurality of different reporting and display means may be utilized to display the difference in air velocity between the plurality of air filter 35. In an exemplary embodiment, a plurality of colored gases 123 may be utilized to illustrate which of the plurality of air filters has the least amount of air flow restriction therebetween. The colored gases 123 may be utilized to illustrate visually to a viewer the air flow through the air filters. The greater amount of colored gas 123 that is viewable to an observer, the more air flow that is being allowed through the filter, thereby allowing the observer to determine which of the plurality of air filters is the most and/or least restrictive.
In another exemplary embodiment of the present invention, the device 1 and the plurality of wind meters may be connected to a periphery computation device 125. The periphery computation device 125 may be a computer 127. The computer 127 may receive statistical information from the device 1 wind meters and may use the data to graphically or statistically display the results to the viewer relating to which air filter 35 had the least and/or most amount of air restriction. The computer 127 could also show in graphical form which air filter 35 had the best air flow therethrough. In an exemplary embodiment, the computer 127 may be connected to a printer (not shown) whereby a viewer may print the results of the air velocity device 1 whereby a viewer may be able to see which air filter 35 results in the least amount of air restriction therethrough.
Thus, specific embodiments and applications of a safety device system have been disclosed.
