A helmet has: a helmet shell; a battery connected to the helmet shell; an electric connector connected to the helmet shell; and at least one electric device electrically connected to the battery and to the electric connector. In response to the electric connector being electrically connected to an external power source and receiving electric power for the external power source, electric power is supplied to the at least one electric device from the electric connector. In response to the electric connector not receiving electric power from the external power source, electric power is supplied to the at least one electric device from the battery.

A protective member such as a helmet includes an outer layer and an inner layer interconnected by multiple connectors, such as extension springs, under tension along their longitudinal axis. The connectors absorb energy from an impact force by resisting further tension along their longitudinal axis and allow the outer layer and inner layer to move relative to each other. In the helmet application, the head of a user experiences less impact force, reduced change in momentum or position of the head and neck, reduced head and neck loads and reduced amounts of linear and rotational acceleration. The protective member can be used in numerous applications and environments, including for participants in sports, in applications including bumpers, passenger cabins, car seats and beds.

A programmable electronic helmet and a method of using the helmet are provided. The programmable electronic helmet includes a hard frame strappable to a head of a user, at least one gyroscope, an accelerometer, a user interface, at least one camera positioned on the hard frame, a display positioned a location that is in the peripheral field of vision of the user, wherein the display is configured to communicate information to the user, and a wireless communication apparatus. The programmable electronic helmet further includes one or more processors, wherein the one or more processors are configured to analyze images captured by the at least one camera to approximate a location of one or more objects in an area surrounding the user, and a memory, coupled to the processor, configured to store data acquired by and sent to the programmable helmet.

A helmet for a smart cycling equipment. The helmet includes a main body, a left speaker, a right speaker, a control interface, a charging interface, a microprocessor, a wireless communication module, and a battery. The main body includes a shell and a flange connected to the shell and surrounding the shell. The flange includes a front portion, a rear portion, a left portion, and a right portion. The left speaker is arranged on the left portion. The right speaker is arranged on the right portion. The control interface and the charging interface are arranged on the flange. The wireless communication module is connected to the microprocessor. The battery is connected to the charging interface.

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.

A multifunctional and intelligent industrial helmet is provided, comprising a helmet body and a lining layer provided on the helmet body, wherein a multifunctional control system is further provided within the helmet body; the multifunctional control system comprises a main control module, and a harmful gas detection module, a talkback module, a camera module, a power supply module, a storage module and a network module, all of which are electrically connected to the main control module; and, during the operation, the camera module records videos or takes pictures and stores the videos or pictures in the storage module, or transmits the videos or pictures to a background server in real time via the network module.

An active awareness control system and method for a helmet with a rigid shell that spatially divides a shell interior from a shell ambiance includes receiving at least one playback-sound signal, generating in the shell interior from the at least one playback-sound signal playback sound, and receiving and processing at least one ambient-sound signal representative of sound occurring in the shell ambience to detect the at least one desired-sound signal. The generation of the at least one playback sound is put on hold when the at least one desired-sound pattern is detected.

An automatic noise control system and method for a helmet with a rigid shell that is configured to spatially divide a shell interior from a shell ambiance include generating in connection with at least one loudspeaker disposed in the shell interior anti-sound in the shell interior based on at least one input signal. The anti-sound is configured to attenuate sound occurring in the shell interior through destructive superposition. The system and method further include providing the at least one input signal by at least one of picking up sound in the vicinity of the loudspeaker in the shell interior, picking up vibrations of the shell, and picking up sound in the vicinity of the shell exterior.

Active noise reduction systems and methods for a helmet with a rigid shell that spatially divides a shell interior from a shell ambiance include receiving at least one desired-sound signal representative of at least one desired sound pattern occurring in the shell ambience, and generating, based on the at least one desired-sound signal, anti-sound that is configured to interact with internal sound occurring in the shell interior through superposition. The internal sound includes first internal sound components and second internal sound components, the first internal sound components not corresponding to the at least one desired sound pattern and the second internal sound components corresponding to the at least one desired sound pattern. The anti-sound is further configured to attenuate the first internal sound components, and to amplify, not attenuate, or attenuate to a lesser degree than the first internal sound components the second internal sound components.

An electronic motorcycle helmet. The electronic motorcycle helmet includes a helmet having an aperture therein that can receive a head therethrough. A visor is disposed on a front side of the helmet and a display is disposed on an interior surface of the visor. A microprocessor, including a logic that receives a command input directed to one of a plurality of subsystems, toggles the subsystem between an activated state and a deactivated state, and displays a status window on the display corresponding to the subsystem. The plurality of subsystems includes a plurality of cameras disposed about the helmet, wherein each of the cameras is operably connected to the display and can apply a low-light filter for low-light conditions. Other subsystems include a wireless transmitter to wirelessly communicate with an external device, a GPS system, and a battery disposed at a lower edge of the rear side.
