Systems and methods for coupling a clip to a wearable item with a receiver. The methods involve: receiving the clip's latch structure in the receiver's channel; sliding the latch structure's side members against a channel surface; sliding the latch structure's latch body against the channel's opening edge; bending the latch body by biasing the latch body towards the latch structure's common body portion as the latch body slides against the edge; inserting the latch body and the side members through the channel until at least the free end of the latch body no longer resides in the channel, the latch body automatically unbending when the free end of the latch body no longer resides in the channel; and preventing at least the free end of the latch body from re-entering the channel such that the clip is coupled to the wearable item.

Arrangements described herein relate to systems, apparatuses, and methods for a headset system that includes a transducer configured to collect physiological data of a subject, a device housing configured to support the transducer, an insert portion disposed on the device housing, a support structure comprising a baseplate and a receiving portion, and a head cradle supported by the baseplate. The receiving portion extends in a direction that is oblique with respect to the baseplate. The insert portion is sized and shaped to engage the receiving portion to removably attach the device housing to the baseplate.

The air-conditioned helmet is a protective structure. The air-conditioned helmet is configured for use with an individual. The air-conditioned helmet forms a protective shell around the head of the individual. The air-conditioned helmet is a temperature-controlled space within the protective space formed by the air-conditioned helmet. The air-conditioned helmet comprises a helmet structure, cooling structure, and a control circuit. The control circuit and the cooling structure attach to the helmet structure. The cooling structure controls the temperature of the protective interior space formed by the helmet. The control circuit: a) controls the temperature of the protective space formed by the helmet structure; and, b) tracks and announces the GPS coordinates into the protective space formed by the helmet structure.

A directional lock or a headgear or interface assembly has one or more directional locks that include a catch arrangement for initiating or assisting in movement of a lock member of the direction lock. In some configurations, the catch arrangement assists movement of the lock member in only a portion of a range of travel of the lock member. In some configurations, the directional lock has a housing and a sleeve and the catch arrangement has a catch arm carried by the sleeve. The catch arm includes a catch end that contacts the lock member, which can be a lock washer in some configurations.

A head guard is provided. The head guard includes one or more sensors as part of an sensory input and communications system. The head guard wirelessly communicates data to remote computing devices for intelligent data collection.

A helmet mount system for attaching a device to a helmet comprises a threaded interface assembly having an outer portion and a threaded insert received within a cavity formed in the outer portion. The outer portion has an inward facing surface configured to receive an adhesive layer for coupling the inward facing surface to a surface of the helmet. In a further aspect, a ballistic helmet having the helmet mount system herein is provided, wherein the helmet mount system does not penetrate a ballistic layer of the ballistic shell.

A mounting device having a mounting assembly for mounting a pair of goggles to a helmet is provided. The mounting assembly is configured to provide at least three degrees of freedom of movement using one or more actuation mechanisms for locking and unlocking a position of the mounting device. The number of actuation mechanisms is less than a number of degrees of freedom. In some aspects, the number of actuation mechanisms is one. A rotation base connects the mounting assembly to the helmet, and a goggle linkage connects the mounting assembly to the goggles. Various single actuation mechanisms, including a sliding mechanism, a friction-based wire/brake mechanism, and a floating friction brake mechanism, are provided.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.
