DETAILED DESCRIPTION
Referring to the drawings, FIG. 1 shows an enclosure 100. In the illustrated embodiment, the enclosure 100 includes an enclosure body 102, ballistic tolerant plates 110a, 110b, and multiple component enclosures 104a-104c. In the illustrated embodiment, the enclosure body 102 is formed from a light weight material while utilizing ballistic tolerant plates 110a, 110b that may be formed from heavier materials to withstand impact from a projectile. In the illustrated embodiment, the enclosure 100 can protect computer components 112a-112c (shown in FIG. 2) while minimizing the weight of the enclosure 100.
In the illustrated embodiment, the enclosure body 102 is formed from a lightweight material to minimize total weight of the enclosure 100. In the illustrated embodiment, materials for the enclosure body 102 can be selected to minimize weight while providing a desired level of strength. In the illustrated embodiment, the enclosure body 102 is not required to withstand an impact from a projectile, such as a bullet. In the illustrated embodiment, the enclosure body 102 can be formed from metals, such as aluminum or magnesium, plastics, or composites.
In the illustrated embodiment, the enclosure body 102 forms an enclosure cavity 105. In certain embodiments, the bottom and sides of the enclosure cavity 105 are integrally formed from the same material. In the illustrated embodiment, the enclosure cavity 105 is formed to contain electrical components, such as computer components 112a-112c (shown in FIG. 2). In the illustrated embodiment, the enclosure body 102 can further include features such as ribs 103. In the illustrated embodiment, the ribs 103 can provide structural rigidity to the enclosure body 102. In certain embodiments, the ribs 103 can engage with features of the computer components 112a-112c to locate the computer components 112a-112c within the enclosure cavity 105.
In the illustrated embodiment, the enclosure body 102 can include at least one retaining feature 106 to retain the ballistic tolerant plates 110a,110b within the enclosure cavity 105. The retaining features 106 can include slots, friction modified areas, or any other suitable retaining feature. In certain embodiments, the retaining feature 106 can include an area to allow for bonding or fastening of the ballistic tolerant plates 110a,110b to the enclosure body 102. In the illustrated embodiment, the ballistic tolerant plates 110a,110b slide into the retaining feature 106 slots. Advantageously, the ballistic tolerant plates 110a, 110b can easily be removed to provide access to the components within the enclosure cavity 105 or allow for replacement of the ballistic tolerant plates 110a,110b if damaged.
In the illustrated embodiment, the ballistic tolerant plates 110a,110b can be inserted into the enclosure cavity 105. Advantageously, the ballistic tolerant plates 110a, 110b can stop or absorb energy from projectiles, such as bullets, to prevent the projectile from going beyond the ballistic tolerant plate 110a,110b. In the illustrated embodiment, the ballistic tolerant plates 110a, 110b can be formed of steel, composites, or any other suitable ballistic tolerant material. In certain embodiments, the parameters of the ballistic tolerant plates 110a, 110b are selected based on operating parameters, such as desired weight, cost, expected projectile size, speed and energy. In certain embodiments, the geometric and material characteristics of the ballistic tolerant plates 110a, 110b are selected based on the operating parameters.
In the illustrated embodiment, the ballistic tolerant plates 110a,110b, when inserted into the retaining features 106, can divide the enclosure cavity 105 into multiple component enclosures 104a-104c. In certain embodiments, the enclosure 100 can include any suitable number of ballistic tolerant plates and form any suitable number of component enclosures. Advantageously, the ballistic tolerant plates 110a, 110b can form multiple component enclosures 104a-104c with ballistic tolerant material between the enclosures to prevent a projectile from traversing between the component enclosures 104a-104c. 
Referring to FIG. 2, a multi-channel computer system 200 is shown. In the illustrated embodiment, the multi-channel computer system 200 is enclosed within the enclosure 100 previously described. In the illustrated embodiment, the multi-channel computer system 200 includes a plurality of computer components 112a-112c. The plurality of computer components 112a-112c can be redundant computer components that provide the same functionality in case of failure or malfunction of a single component. In certain applications, the use of redundant computer components is required by operational and industry standards. In the illustrated embodiment, the computer components 112a-112c can perform any suitable function, such as flight control, weapons control, etc. In certain embodiments, the multi-channel computer system 200 can include any suitable number of redundant components.
In the illustrated embodiment, the computer components 112a-112c are disposed within the component enclosures 104a-104c. In certain embodiments, the computer components 112a-112c can contain notched features 113 to locate and align the computer components 112a-112c within the enclosure body 102. The notched features 113 can be geometric shapes or reliefs corresponding to features of the enclosure body 102 to prevent movement or vibration in one or more directions. Further, the notched features 113 can allow for an installer to properly orient the computer components 112a-112c within the enclosure body 102. In certain embodiments, the notched features 113 of the computer components 112a-112c can engage with the ribs 103 of the enclosure body 102.
In certain applications, operational, industrial, or safety guidelines require that the multi-channel computer system 200 can withstand projectiles, such as bullets. In the illustrated embodiment, the layout of the ballistic tolerant plates 110a,110b prevents a projectile from damaging more than one redundant computer component 112a-112c, even if the projectile breaches the enclosure body 102. In the illustrated embodiment, the computer components 112a-112c are arranged horizontally within the enclosure body 102 with ballistic tolerant plates 110a,110b disposed there between, which may allow a projectile to damage a single computer component 112a, but will not allow the projectile to traverse the ballistic tolerant plates 110a,110b to damage a second computer component 112b,112c. 
In the illustrated embodiment, the redundant components 112a-112c can continue to perform desired functionality, even if one computer component 112a is damaged. Advantageously, a single projectile may not disable all redundant computer components 112a-112c enclosed within the enclosure 100. Therefore, the enclosure 100 can provide ballistic protection for computer components 112a-112c with reduced cost, weight, and simplified installation.
In the illustrated embodiment, a cover 114 can be located above the enclosure cavity 105 to enclose the enclosure cavity 105 and contain the computer components 112a-112c. In the illustrated embodiment, the cover 114 is formed from a material similar to the enclosure body 102, such as lightweight metal, such as aluminum or magnesium, a plastic, or a composite.
