A ballistic helmet system having an integrated circuit layer electrically coupled to one or more powered devices, where the ballistic helmet is configured to operate and control the powered devices. The ballistic helmet system comprises a base layer configured to retain the circuit layer. The circuit layer comprises one or more circuit substrates, which may be formed of a flexible material capable of withstanding elevated temperatures that may result from the bonding and curing process of the helmet components.

A wireless communication system comprises a first wireless communication device for a first team member, and a second wireless communication device for a second team member. The first wireless communication device comprises a microphone and a transmitter for transmitting an oral message via a first wireless communication protocol. The second wireless communication device comprises a main transceiver, a wearable audio device, and a support configured for mounting the main transceiver onto hockey shoulder pads of the second team member in a location physically remote from the wearable audio device.

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 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.

An adapter assembly for attaching a circumaural device to a mounting interface on a helmet comprises a fastener element configured to releasably couple to the mounting interface. A pressure relief assembly coupled to the fastener element has a pivoting subassembly and an adjustment subassembly. The pivoting subassembly I pivotable about a pivot axis and has a range of travel between an upright position and an extended position. One or more attachment arms have a proximal end coupled to the pressure relief assembly and a distal end for attaching the circumaural device. The adjustment subassembly has a manually operable control portion to cause pivoting movement of the pivoting subassembly toward the upright position to decrease a pressure of an attached circumaural device on a wearer's head or toward the extended position to increase a pressure of an attached circumaural device on the wearer's head.

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

An informatics system that can be head-worn under a helmet and used to provide a wearer's vital statistics and other information to a remote monitoring station, for example in connection with pre-hospital emergency care.
