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 display device for a bicycle, e.g., a Pedelec, and/or a bicycle element, and a method of operating a bicycle with a display device are disclosed. The display device includes a carrier for mounting on a handlebar of the bicycle or for mounting on a bicycle helmet. On the carrier, a plurality of controllable luminous elements are arranged.

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.

A hard hat with symmetric front and back mounting ridges to support a headlamp is described. The hard hat provides mounting ridges to receive insertion slots of a rigid mounting bracket that fit around the ridges. The rigid mounting bracket includes channels to loop a strap through the channels and support a lamp on the bracket. The strap may include a hook and loop fastener system to enable attachment of a variety of lamps to the rigid support bracket. In this way, the hard hat can support a wide variety of headlamps attached to the rigid mounting bracket without destructive alterations to the hard hat. Clips may be added to the rigid mounting bracket to secure or lock the bracket in place during operation and prevent accidental knocks or jarring of the headlamp.

The invention relates to an interface for connecting an optical device and a mobile support which cooperates securely with an imprinted element, the interface having a base arranged to be inserted into the imprinted element, the base being a hollow body. The base accommodates mechanical play compensating structures which are movably mounted within the hollow body so as to project and are arranged in order to bear against a wall of the imprinted element.

An augmented reality display device, includes: a display unit including a thermal camera configured to capture image frames, an image projector, and a display screen; a processing unit including processing structure in communication with the thermal camera and the image projector, the processing structure being configured to process the captured image frames and output processed image frames to the image projector, and a battery; and a strap connecting the display unit and the processing unit.

A magnetic pass-through controller of an in-helmet display includes internal components inside a helmet. The internal components include a magnet assembly holding one or more internal magnets and a swing arm affixed to the magnet assembly and affixed to the in-helmet display. External components outside the helmet include an external magnet housing holding one or more external magnets and an adjuster for manual rotation. The adjuster is coupled to the external magnet housing such that the manual rotation of the adjuster causes a corresponding rotation of the external magnet housing. Magnetic coupling between the one or more internal magnets and the one or more external magnets causes the corresponding rotation also in the magnet assembly and the swing arm.

A helmet accessory mount system may include a shroud configured to be coupled to a helmet and an arm assembly having a first arm configured to rotatably couple to the shroud. The system may also include an accessory interface configured to coupled to an accessory and configured to engage the arm assembly. The arm assembly may be configured to move from a deployed position to at least one storage position. The accessory may be configured to be positioned between the accessory interface and the helmet when the arm assembly is in the at least one storage position.

The invention relates to a head mounted image capture device (1) for capturing facial motion of a user. The device (1) includes a helmet (2) with side portions (5), each for resting on the sides of a user's head. Each side portion (5) includes an arm (6) to which a respective camera (7) is mounted. Each camera (7) is positioned laterally of a user's face for capturing image data relating to a respective side of the user's face.

An augmented-reality system is combined with a surveying system to make measurement and/or layout at a construction site more efficient. A reflector can be mounted to a wearable device having an augmented-reality system. A total station can be used to track a reflector, and truth can be transferred to the wearable device while an obstruction is between the total station and the reflector. Further, a target can be used to orient a local map of a wearable device to an environment based on a distance between the target and the wearable device.
