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.

Whiplash reduction systems and devices and methods to use the same. In an embodiment of a system of the present disclosure, the system comprises a front anchor strap coupled directly or indirectly to a headgear; a top anchor coupled to the front anchor strap, the top anchor having a connector coupled thereto, the connector configured to connect to at least one rear strap; a first retainer configured to fit within apertures defined within the headgear and to wrap around at least part of the headgear and at least part of the front anchor strap to secure the front anchor strap to the headgear at or near the apertures; and a plate having a central portion defining a recessed portion and further having a first side portion and a second side portion.

A hydration system including a fluid reservoir, a fluid path in communication with the reservoir, and a magnetic quick connect interposed in the fluid path is disclosed. A fluid delivery system for a hydration system is also disclosed that includes a magnetic quick connect interposed in a fluid delivery path of the delivery system. The magnetic quick connect can also be used in a wide variety of fluid delivery systems. A kit for forming a fluid delivery system for a hydration system is also disclosed, as are various components of a hydration system.

An intelligent head-mounted apparatus, including: a head-mounted apparatus body; a communication element operable to receive navigation signals and a locating element operable to determine location information, both of which are disposed on the head-mounted apparatus body; and a controller disposed on the helmet apparatus body and operable to control at least one vibrating element based on the navigation signals and the location information; vibrating elements operable to vibrate under the control of the controller. The user of this apparatus can learn navigation information only by perceiving the vibration without being distracted by observing the navigation information, so that the safety of receiving navigation information during riding is improved. A control method of the intelligent head-mounted apparatus is further provided.

The present invention discloses a method for interlocking a shared bicycle and an intelligent safety helmet, and the method comprises the following steps: (1) providing an electronic frame lock and an intelligent safety helmet for using cooperatively on a shared bicycle respectively, interlocking both of them when the shared bicycle is parked; (2) checking the current state information of an electric lock and a safety helmet lock simultaneously when a user uses the mobile intelligent terminal to scan the shared bicycle; (3) unlocking of the electric lock and the safety helmet lock when the verification is passed; (4) wearing an intelligent safety helmet before using the bicycle; (5) beginning to record the trip information by the intelligent helmet after the user puts on the intelligent safety helmet; (6) stopping the voice broadcast function and terminating the recording of the trip information when the state information of the electronic frame lock and the safety helmet lock which is checked shows that the electronic frame lock and the safety helmet lock are locked, after the user terminates the using of the bike. The invention also discloses an interlocking device for a shared bicycle and an intelligent safety helmet implementing the above-mentioned method, which makes that the bicycle and the intelligent safety helmet are always in a state that they are used in cooperation with each other.

A helmet has a helmet shell and a visor pivotally connected to the helmet shell. The helmet further has an electrical device attached to one of the visor and the helmet shell. First and second helmet electrical contacts are attached at both sides of the helmet and are adapted for electrically connecting to an electrical power source. First and second visor electrical contacts are attached to each side of the visor and are electrically connected to the electrical device. The first and second visor electrical contacts are pivotally connected to the helmet shell about first and second pivot axes respectively. The first and second visor electrical contacts are in contact with the first and second helmet electrical contacts respectively, at at least one position of the pivoting visor.
