An apparatus and a method for refining a geographical location based on dynamic characteristics of a helmet are disclosed. A piece of angular velocity information is sensed through a gyroscope and then compared with a piece of basic angular velocity information to generate a piece of dynamic information of the helmet body. The piece of dynamic information, the piece of location information, and the piece of magnetic flux information are marked on an electronic map to generate a piece of refined geographical location information which is then sent to an output unit to be outputted. Thus, a higher resolution of the current geographical location is obtained.

A protective headgear (1) comprising: a protective helmet (20) that defines an interior space (31), that comprises an inward major surface, and that comprises a forward window with a windowpane (27); a head suspension that is connected to the helmet; and an air supply module (50) mounted at least partially within the interior space defined by the helmet, wherein the air supply module comprises central, right lateral, and left lateral trunks (53, 54, 55) that are configured so that when the module is mounted within the interior space defined by the helmet, selected central, left and right areas of the inward major surface of the helmet combine with the central, left lateral and right lateral trunks of the air supply module to respectively define a central air supply passage and left and right lateral air supply passages for delivering air to a wearer of the protective headgear, and, wherein the air supply module comprises an external, remote handle (70) that is remotely connected to an air valve that is operative to control a rate at which air is directed into the central air supply passage in comparison to a rate at which air is directed into the left and right lateral air supply passages.

The present invention also concerns a helmet on which the image acquisition device is installed. The present invention also concerns the related method to acquire and process images.

An apparatus may include a protective shell to protect a head of a wearer of the apparatus, where the protective shell may include a void of material positioned to be proximate a face of the wearer of the apparatus when wearing the apparatus. The apparatus may additionally include a visual interface device located proximate a border of the protective shell and the void of material, and a controller to provide display signals to the visual interface device.

A system is provided for use by athletes and their coaches during practice. The system includes an electronic system configured for inclusion in a helmet. The electronic system includes a transparent display screen coupled to the helmet, a processor coupled to the transparent display screen, a camera coupled to the processor and a first wireless transceiver coupled to the processor. The system also includes a handheld processing device. The handheld processing device includes a second wireless transceiver configured to communicate video content with the first wireless transceiver, an interactive display screen configured to display the first video and a video editing application configured to edit the first video to generate a second video including a simulated player technique superimposed in the first video. The second video is communicated from the handheld processing device to the electronic system for display to the athlete via the transparent display screen.

In one aspect, a shroud assembly for headgear includes a frame formed of a polymer material having a shape that matches a contour of the headgear. An insert is formed of metal or metal alloy and is attached to a front side of the frame. The insert is configured for removable attachment to a mounting assembly. The frame includes first and second spaced flexible walls disposed on the front side of the frame on opposite sides of the insert. The first and second flexible walls are spaced a sufficient distance apart to provide an interference fit between the mounting assembly and the first and second flexible walls. In another embodiment, the shroud assembly further includes a friction pad disposed on a rear surface of the frame for increasing friction between the shroud assembly and the headgear. In another aspect, a method for attaching a mounting assembly to headgear is provided.

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.

A system for providing controls signals to a wireless remote camera comprises a signal generating device that presents forward and inverse polarity pulse trains. A transmitter data converter circuit has a forward polarity input point for receiving the inverse polarity pulse trains and an inverse polarity input point for receiving the forward polarity pulse trains, and converts the forward and inverse polarity pulse trains to a conditioned unitary pulse train. A modulator circuit modulates the conditioned unitary pulse train onto an RF carrier. A demodulator circuit demodulates the modulated output wave to produce a reproduction of the conditioned unitary pulse train. A receiver data converter circuit converts the conditioned unitary pulse train to conditioned forward polarity pulse trains and conditioned inverse polarity pulse trains. A camera control circuit produces control signals based on the conditioned forward and inverse polarity pulse trains. A wireless remote camera receives the control signals.

A system may include a space suit helmet. The space suit helmet may include a surface structure, an inner surface structure, and a waveguide display. The inner surface structure may be configured to maintain an oxygenated environment within an interior cavity of the space suit helmet, wherein a user is able to see through the inner surface structure and the surface structure. The waveguide display may be implemented at least one of in or on the space suit helmet. The waveguide display may include a waveguide and an optical system configured to project images at least through the waveguide to be displayed to the user.
