Abstract: Described is an energy share pack comprising a housing, at least one energy storage component within the housing, at least one energy conversion component within the housing, and a connection point for connecting to more than one of energy users, energy sources and other energy share packs simultaneously for sharing energy. The energy share pack may have an energy generation component for generating harvestable energy, and two or more ports of any combination of the following types: bidirectional power port, bidirectional USB port, unidirectional output power port, and unidirectional input power port. The share pack ports may operate simultaneously at different voltage levels, and at least one port may be bi-directional. Furthermore, the share packs may have an integrated display for providing information on the energy share pack in which the display is integrated and information about other energy share packs connected thereto.

Abstract: A helmet accessory attachment member includes a finger-actuatable lock configured to secure an accessory attachment member mount to a helmet mount as part of securing an accessory such as a mandible guard to a helmet. The lock includes a pivot arm with a rotation axis that is parallel to the helmet surface, and also includes one or more blocking surfaces on the pivot arm to engage with grooves on the helmet mount. The lock may be positioned on a slidable insert of the accessory attachment member.

Abstract: Earphones which attach to an interior of a helmet are disclosed. Physical attachment of the earphones to the helmet result in an electrical connection in some embodiments. The headphones may be used without the helmet through the use of strap holder adapters in some embodiments.

Abstract: Attachment systems for releasably securing an accessory to an article, such as a helmet, are disclosed. In one embodiment, an attachment system (100) includes an attachment plate (102) that includes engaging features (108, 110) which engage corresponding engagement features on an attachment base (104). At least one of the engaging features (110) on the attachment plate is associated with a flexible member (112), and is movable between a locked configuration and an unlocked configuration via deformation of the flexible member. A pair of grips (114) are provided on opposing ends of the flexible member, and the grips are pressed toward one another to move the movable engaging feature between the locked and unlocked configurations.

Abstract: Systems and methods for attaching an accessory to a helmet. A helmet accessory mounting interface may be attached to a receptacle. The receptacle may be removably or permanently received by a carrier. The carrier may be attached to a helmet having a particular shape and size. The carrier also may be configured to receive any selected type of a plurality of receptacle types which, in turn, corresponds to a particular mounting interface for a helmet accessory. The receptacle may be receivable, in some embodiments removably, by any one of a number of different types of carriers.

Abstract: A helmet assembly includes a face shield and a single, center top mounting arrangement that operatively connects a center top location of the face shield to a center front mount on the helmet. The face shield can be raised and lowered about a pivot axis provided in the mounting arrangement between a tilted up, non-use position and a lowered, deployed position. The mounting arrangement can include a detent and two recesses, wherein the detent engages a first recess at a slightly forwardly displaced position to allow ventilation between the helmet and mandible and the face shield and a second recess at the tilted up, non-use position. The recess and detent engagement can be overcome by easy manual force acting on the face shield to reposition the face shield.
