A head-worn system has one or more illumination, imaging, communication, and/or other controlled elements electrically connected to a switch element (e.g., a piezo switch) positioned on the head-worn system so as to be overlying an area of a wearer's masseter muscle when worn on the wearer's person. The switch element is configured to be activated responsive to clenching of the wearer's jaw. The one or more controlled elements may be arranged to provide directional lighting/imaging from the point of view of the wearer, for example from the area of the wearer's zygomatic bones, when the head-worn system is worn on the wearer's person.

The invention relates to a replaceable adaptor for attaching a headset device to a helmet, which comprises: (a) a lower portion at a lower level having a shape suitable to be accommodated within a helmet cavity at the helmet; and (b) an adaptor cavity which is adapted to accommodate said headset device; wherein when a need is arisen to attach another headset having a different shape or dimensions to a same helmet, or when a need is arisen to replace the helmet by another helmet having a cavity of different shape or dimensions, said adaptor is replaced accordingly.

A ballistic helmet comprising a ballistic shell, wherein within the thickness of the ballistic shell, or inside the ballistic shell, there is provided one or more circuit layers forming a circuit, which circuit comprises a power bus and a data bus, and wherein one or more power connections and one or more data connections are provided on the inside and/or on an edge of the ballistic shell for providing power and data to/from one or more electrical devices through the circuit.

Disclosed is a connector for providing audio signals. The connector can include an audio signal and power cable having a first end and a second end, and an interface communication connector disposed at least proximate to the first end. Further, the connector can include a ground, power, and audio signal connector disposed at least proximate to the second end, wherein the ground, power, and audio signal connector is configured to accept a plurality of different audio signal and power cables from different noise-protection devices having differing pin configurations. Further still, the connector can include at least a first audio input signal cable in contact with the audio signal and power cable, wherein the audio input signal cable is configured for transmitting one or more of the audio signals through the interface communication connector to at least one of a vehicle and an extra-vehicular source.

A method of using an augmented audio enhanced perception system, comprising: tracking at least one object with at least one helmet mounted sensing unit; processing at least one of the at least one tracked object and an ambient sound by a processing unit; and, providing at least one of a synthesized audio signal and a processed ambient sound to a first user of the system using an audio interface unit, to provide information concerning the at least one object to the first user.

An earmuffs system for noise reduction including an external microphone used in combination with active noise cancellation technology for the reduction of wind or other noises typically experienced while riding a vehicle such as a motorcycle, snow machine or ATV, the earmuffs system including a first earmuff including a first speaker and a first microphone therein; a second earmuff electrically coupled to the first ear muff, the second ear muff including a second speaker and a second microphone therein; noise cancellation circuitry for receiving first sounds from the first microphone and the second microphone and processing the first sounds by in part canceling the first sounds to form a first sound output that is provided from the first speaker and the second speaker; a third microphone placed external to the first earmuff, the third microphone supplying second sounds for the first speaker to output as a second sound output without the second sounds undergoing noise cancellation processing; and a fourth microphone placed external to the second earmuff, the fourth microphone supplying third sounds for the second speaker to output as a third sound output without the third sounds undergoing noise cancellation processing.
