摘要:
A real-time virtual reality welding system including a programmable processor-based subsystem, a spatial tracker operatively connected to the programmable processor-based subsystem, at least one mock welding tool capable of being spatially tracked by the spatial tracker, and at least one display device operatively connected to the programmable processor-based subsystem. The system is capable of simulating, in virtual reality space, a weld puddle having real-time molten metal fluidity and heat dissipation characteristics. The system is further capable of importing data into the virtual reality welding system and analyzing the data to characterize a student welder's progress and to provide training.

An integrated helmet and respirator system comprises a shell defining a helmet portion, the helmet portion being bounded by a peripheral edge. An annular shroud has an upper edge and a lower edge, the upper edge removably attached to the peripheral edge of the helmet portion and the lower edge attached to an annular frame member. A front portion of the annular shroud defines a visor. A one-way exhaust valve is received within an opening in the annular frame member. The one-way exhaust valve is configured to allow an exhalation gas exhaled by a user to exit an interior of the integrated helmet and respirator system and to prevent or minimize ambient air from entering the interior of the integrated helmet and respirator system. A neck dam extends downward from the frame and is configured to prevent or minimize ambient air from entering the interior of the integrated helmet and respirator system.

Football helmet with video system has a rigid shell with front and back portions. An impact absorbing pad assembly and underlying comfort liner assembly are removably attached in the shell. A face guard of connected bars has a center bar connected to the front portion of the shell by one or more connectors with a nose bumper between the center bar and the shell. The nose bumper has a concave inner surface engaged flat against a convex outer surface of the front portion and a video optics housing extending forwardly of the nose bumper and containing an imager. A battery housing is connected in the shell for a battery, a circuitry housing is connected to the shell for video camera circuitry and wiring connects the imager and the battery housing to the video circuitry.

In described embodiments, a wrestling headgear assembly is disclosed. The headgear includes a first ear piece and a second earpiece connected to the first earpiece by at least two connections. Each of the first and second earpieces comprises a generally planar inner layer constructed from a compressible material. The inner layer has a generally central inner opening extending therethough. A generally convex outer layer is fixedly attached to the inner layer. The outer layer is constructed from a rigid material and includes a plurality of outer openings aligned with the inner opening. A sound speaker is located between the inner layer and the outer layer such that the speaker is aligned with the inner opening.

Substantially-linear dipole antenna for safety helmets, of the type comprising two conductive branches arranged to be electrically connected, at one of their ends, to respective radio equipment, the two conductive branches being disposed substantially aligned. The two conductive branches have a length essentially equal to ¼ of the expected operative wavelength of the radio equipment. The dipole antenna further comprises at least two conductive arms, each having a length essentially equal to ½ of said operative wavelength, each of which is electrically connected respectively to the free end of both of the two conductive branches, both having a length essentially equal to ¼ of the operative wavelength.

A smart helmet includes a helmet shell, a visor, and a projector mounted on the helmet shell. The helmet shell defines an internal cavity and a passage communicating with the internal cavity. The internal cavity is configured to receive an user's head. The visor is rotatably coupled to the helmet shell, and is configured to expose or cover the passage. The projector is configured to introduce content for display onto the visor.

The environmental system for motorsports helmets includes a helmet and backpack containing various components of the system. The helmet includes an inlet and air passages for forced air ventilation, a tube conducting drinking water from a helmet inlet to the mouth of the helmet wearer, and a radio communications headset. The helmet is a full-face helmet having an openable transparent face shield and visor formed with the face shield as a unit. A backpack is provided with the helmet, the backpack containing a motor driven fan to supply air to the helmet. The air is filtered through an external filter on the pack, before entering the fan and ventilation system. A water tank is also included in the backpack, allowing the helmet wearer to draw water from the supply. A conventional communications transceiver is also provided with the backpack, the transceiver connecting to the headset within the helmet.
摘要:
A method and apparatus for monitoring impacts on or between bodies is disclosed. In one application, head impacts and the performance of a helmet during impacts are monitored by determining head motion and helmet motion relative to a common origin and/or frame of reference in response to sensed head motion and sensed helmet motion. The head motion in the common frame of reference is compared with helmet motion in the common frame of reference to determine performance of the helmet. The apparatus may include a surface-mountable motion sensor having a reusable sensing circuit and a disposable mounting structure.
摘要:
A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. The helmet has a chin bar that extends forward of the face of the individual wearing the system. At least one manually actuated control for regulating one aspect of operation of the system is mounted to the chin bar. Sometimes the control is a button that is depressed to control the operation of a helmet moutned fan that draws air into the hood or toga. A microphone may also be mounted to the chin bar.

The object of the present invention is to prevent a microphone from misalignment or drop caused by wind and shake during driving, and careless touch on the MIC with a hand a shoulder. There is the mounting device mounting a microphone around the mouth of a wearer of an open-face helmet, the mounting device having deformation function for the wearer and formed with foamed synthetic resin materials generating repulsive resilience against deforming stress to cover from around the mouth to the left side part of a helmet shell configuring the outmost layer of the open-face helmet.
