A cover apparatus adapted to cover at least a portion of an ear for protection from the elements, artificial heat sources, and the like, is provided. Such a cover is produced in uniform structure such that any properly sized implement may be affixed to either a left or right ear. Additionally, the manner of affixing is provided through the provision of the ear cover exhibiting sufficient elasticity for pressure fitting around a subject ear auricle and lobe simultaneously, with lower levels of elasticity exhibited by the middle portion thereof extending between the top and bottom portions. Such a cover thus compresses for proper fitting around the auricle and lobe and does not provide excess pressure in the middle portion, thereby allowing for greater comfort and control to the wearer and leaves a least part of the wearer's ear canal exposed and uncovered to facilitate hearing while affixed.

One embodiment of the present invention relates to a releasable flexible coupling system comprising a base, a coupling member, and a sewn member. The coupling member is fixably coupled to the base across the widthwise dimension on opposite sides of the lengthwise dimension forming a recess between the base and the coupling member. The sewn member comprises a strap, a folded region, and a primary stitch. The strap includes a body and a lengthwise end. The folded region is disposed on the lengthwise end of the strap and includes a portion that overlaps the body. The primary stitch extends through both the folded region and the body of the strap. An optional stiffener may be disposed between the lengthwise end of the strap and the folded region. The primary stitch will also extend through the stiffener if present.

Featured are impact detection sensors that include a nonconductive layer disposed between two conductive layers. Each conductive layer includes an electrical circuit configured to generate a signal in response to an impact. Also featured are devices (e.g., a wearable device or device configured for use with a piece of equipment, such as a vehicle) including a plurality of impact detection sensors. The device having sensors can receive and process data from the sensors and provide situational awareness for users in adverse conditions, such as during combat or wartime. The wearable device may further include one or more inflatable bladders configured to apply pressure to a wound site for treatment.

A safety guard for an ammunition cartridge (cartridge) of a conductive energy weapon (CEW) includes a body having a first electrical contact on a first side of the body and a second electrical contact on a second side of the body opposite the first side of the body. The first and second electrical contacts are in electrical communication with each other through the body. The first and second electrical contacts are configured to contact a first electrode of the cartridge and a second electrode of the cartridge, respectively, when the body is placed over the cartridge. The safety guard is configured to prevent the cartridge from firing when a firing input, such as a trigger pull, is received by the CEW from a user. In implementations the body incudes at least one clip having a projection configured to be inserted in a corresponding depression of the cartridge of the CEW.

A helmet mounted protective shroud apparatus for use with respirators includes a shroud mating component adapted to surround a respirator and a shroud component connected to the shroud mating component. The shroud component includes a fabric component having an edge, a plurality of connection mechanisms connected to the fabric component, and a flap component configured to cover a top of the fabric component, wherein the shroud component is adapted to cover a helmet and surround a wearer's head and neck. The present invention allows a chemical-biological protective hood/shroud assembly to be integrated for use with a helmet and respirator.

Apparatus and methods for reducing injury or damage from an explosive device are disclosed. An example apparatus includes a housing and at least one inflator coupled to the housing. The apparatus also includes a shield coupled to the housing. The shield has a plurality of channels coupled to the at least one inflator. The shield also has a compact position and an expanded position. The plurality of channels are configured to receive a fluid from the at least one inflator and thereby at least partially advance the shield from the compact position to the expanded position.
