An impact force dampening and defusing structure includes a plurality of components arranged in a grid array. A component has a three-dimensional geometric shape that includes an impact receiving surface area and an impact defusing surface area. The impact defusing surface area is larger than, and a distance d from, the impact receiving surface area. The component includes a material composition and, when an impact force strikes the impact receiving surface area of the component and the impact force dampening and defusing structure is in position to protect a body part, the component contributes to reducing pressure on the body part based on the material composition, the distance d, the impact receiving surface area, and the impact defusing surface area.

An apparatus having a plurality of inflatable members, the inflatable members worn in a vertical orientation on a human torso; a collar portion connected to the plurality of inflatable members; and at least one inflation tube connected to the plurality of inflatable members, wherein the inflation tube includes a mouthpiece and a valve to controllably inflate and deflate inflatable members in the plurality. The apparatus is worn by a person underneath a protective vest to provide ventilation of body heat between the person and the protective vest.

A guard, fabricated from a water-resistant, lightweight, nonwoven, antimicrobial fabric, is constructed to be worn by a user for protecting a closed, post-operative sternal incision against exposure to water during bathing and showering. The guard avoids the need for manually holding a protective cover over the incision, and thereby frees the arms and hands of the user, or of a caregiver, for washing, lathering and rinsing.

In accordance with one embodiment of the present invention, a method of multi-use multi-vision modular covers comprising of aggregating multiple devices into physical meshes and virtual networks where devices exchange multi-source data transactions and transmissions between meshed devices to project on their respective screens the exchanged images, videos, and/or visual adjustments to produce multiple video See Through streams between meshed devices in static states and/or in motion. In a preferred embodiment, the invention is combination of devices, cameras, and/or screens that produce See-Through video streams with enhancements to hide, protect, and sustain modular permutations of invisible armors, invisible cloaks, invisible vehicles, invisible crafts, invisible land drones, invisible flying drones, invisible camo nettings, and other invisible configurations managed by manager-of-manager portal platforms that can provision, manage, and monitor all these configurations and deployments during a battle while producing synergies of invisible combined arms tactics to defeat the enemies of God.

Load carriage systems are described including one or more of a first chest panel, a first back panel, and a self-adjusting cummerbund connecting the first chest panel and the first back panel. The self-adjusting cummerbund may include a tensioning mechanism configured to allow the cummerbund to extend and retract, and may be configured to provide varying resistive force. The tensioning mechanism may include one or more of a sliding portion, a continuous patterned length of material that is folded over itself, and an elastic member that is attached to the sliding member and the length of material. Body armor plates may be held between outer and inner chest panels and/or between outer and inner back panels. A strip of webbing may be used to secure the body armor plate between the outer and inner panels.

A force defusing structure includes first and second plurality of spherical shaped objects. A first spherical shaped object is proximally positioned to two or more second spherical shaped objects. When a force is applied to the first spherical shaped object, the first spherical shaped object collides with the two or more second spherical shaped objects to defuse the force based on a multi-dimensional collision between the first spherical shaped object and the two or more second spherical shaped objects.

Embodiments of universal adapter system including a receiver component having base portion configured to be coupled to a base belt worn by an individual and a locking mechanism which is operative to be engaged to a mounting bar of an adapter component that is secured to a dynamic load carriage apparatus, wherein the mounting bar is capable of a sliding action that compensates for a shift in load that is associated with the individual are disclosed. In operation, the receiver component may be engaged and disengaged from the adapter component while being worn by the individual using a single-handed operation.

A chest protector includes a structure for protecting at least a portion of a cardiac silhouette of a user. The structure may include a base assembly, a pivot plate assembly, and a fulcrum block positioned between the pivot plate assembly and the base assembly. The pivot plate assembly is positioned to pivot on the fulcrum block. In some embodiments, the pivot plate assembly and the fulcrum block may include compressible and resilient material. The structure may be shaped, sized, and positioned to coextend with a region of the user's cardiac silhouette. In some embodiments, the pivot plate assembly includes two pivot plate portions oriented at an angle relative to one another. The pivot plate portions may be connected with a flexible hinge, such as a living hinge.

A data collection and display system for use in a combat sport including: i. A trunk protector for a combat sport participant, the trunk protector including: a. protective padding, b. at least one impact sensor, c. at least one microprocessor integral with the protective padding, for collecting and analyzing data from the at least one impact sensor, d. at least one display area, integral with the trunk protector, for displaying information related to the combat sport and combat sport participant; and an energy based method for scoring combat sports.

A weighted chest protector, comprising a first connector comprising of two or more corresponding parts, a second connector comprising of two or more corresponding parts, a front panel comprising of one or more of the two or more corresponding parts of the first connector, a rear panel, an adjustable shoulder panel, comprising a first end comprising of one or more of the two or more corresponding parts of the first connector for connecting the shoulder panel to the front panel of the weighted chest protector, a second end comprising of one or more of the two or more corresponding parts of the second connector for connecting the shoulder panel to the rear panel of the weighted chest protector via a stability strap, a weight affixed proximally to the second end of the shoulder strap of the weighted chest protector, and a stability strap with a first end and a second end, the first end comprising of one or more of the two or more corresponding parts of the second connector for removably connecting to the second end of the shoulder panel, and the second end removably connected to a lower portion of the rear panel.
