A method and apparatus are provided for allowing a user to change the stiffness of their headband, thus changing the clamping force of the headset. The section properties of the headband equivalent spring, which is a cantilevered beam, are changed by engaging a secondary spring, which is also a shorter cantilevered beam. The change is achieved by manipulating the effective length of the secondary spring, which can be accomplished with a set of clamps. Thus, the stiffness of the headband can be modified to the desire of the user.

An eye mask has magnetic bodies and self-heating warm members, which are inserted in eye pads on a mask member to be placed over eyeball parts. If required, vibrators and illumination bodies may be additionally placed in the eye pads. Thus, fatigue on the eyes and surroundings thereof can be relieved by the magnetic actions of the magnetic bodies and the warming effects of the warming member, in addition to expected effects of restoring ocular functions, recovering from various ocular diseases, and so on. Furthermore, the surface of each of the eye pads is gradually curved like the inner surface of a sphere. When the eye pads are press-contact to the eyeball parts at predetermined pressures for a long time, the cornea can be warmed by the warming members so that the shape of the cornea can be changed along the shape of the eye pad, resulting in the effects of recovering from eye sight disorder such as pseudo-myopia, moderate farsightedness, or moderate astigmatism.

A magnetic fastening device with discrete slidable adjustments, comprising first and second sheets, each having a plurality of magnetic section elements with first and second poles disposed in alternating groups defining predetermined abutting patterns. The magnetic section elements are abuttingly disposed in two groups. In one group, the elements' magnetic field is disposed in one direction perpendicular to the sheets. In the other group, the elements' field is disposed in the opposite direction. The groups repeat themselves in an alternating pattern. The movement of the first and second sheets is constrained to keep them in an abutting relationship with respect to each other over a predetermined path over the first and second sheets, thereby permitting the sheets to be slidably movable along a predetermined distance relative to each other in discrete steps that overcome the attraction and repulsion forces of the magnetic section elements upon the application of a pulling force of a predetermined magnitude.

A photovoltaic powered charging unit is mounted in a head covering, such as a cap or hat, for a patient who has an inductively chargeable medical device implanted in his head. The implanted device includes an implanted battery which powers the device. The photovoltaic cells provide continuous charging for the implanted battery and power for the implanted device when subjected to light. The charging unit includes a nonphotovoltaic cell that may be used to charge the implanted battery and power the implanted device in the absence of sufficient power from the photovoltaic cells. The cap has a sending coil located so that when the wearer dons the cap, the sending coil aligns with a receiving coil implanted in the patient's skull or brain. The implanted receiving coil is coupled to provide charging current to the implanted battery and power to the implanted device.

A ratchet mechanism for the headband of a protective helmet or other headgear is designed to function in high-temperature environments, while still allowing for ready adjustment of the size and fit of the headband. In this regard, the ratchet mechanism includes a rotational element that has a pinion adapted to mate with and engage the respective rack gears of the overlapping rear end portions of the headband, such that rotation of the rotational element causes lateral movement of the overlapping rear end portions with respect to one another. A spring assembly associated with the rotational element engages a ring gear defined by an insert received and retained in the housing so as to resist rotation of the rotational element relative to said housing sections. Since the spring assembly and insert are preferably manufactured from metal, they do not suffer from warping problems, and therefore, the ratchet mechanism continues to function properly even in high-temperature environments.

An augmented-reality helmet comprises a full-face motorcycle helmet with a look-down micro-display that projects a virtual image in-line with the helmet's chin bar. In order to accommodate the power requirements, the helmet includes a battery pack mounted at the base of the motorcyclist's skull. A wind turbine charges the batteries. Exhaust from the turbine is then deducted through the helmet to cool the battery pack and / or the motorcyclist's head. The turbine is controllable so that it can operate as a circulating fan to provide ventilation. A digital gyroscope provides a control input to a controller for operating a steerable headlight of the motorcycle to track the rider's head movements; and provides acceleration output to an algorithm that will contact emergency responders if the rider is non-responsive after a collision. A 170 degree rear-view camera is mounted within an aerodynamic fairing on the back of the helmet.

Disclosed is a protective helmet and a method for mitigating or preventing a head injury, in which a shock-absorbing, or shock-absorbing and comfort-providing, inner wearing unit, which can comprise liners, comfort pads, protective pads, nubbed cages and / or strapped wearing units (for example spider-shaped wearing elements, wearing straps, head bands or the like), is divided into a shell-side insert and a head-side insert, which can be counter-rotated (preferably starting from application of a predetermined force) in at least one direction, wherein a sliding surface is provided that assumes the function of a rotational surface, so that the angular acceleration introduced by a blow is drastically reduced or prevented because the head-side insert and the shell-side insert, and thus the head of the wearer and the outer helmet shell, can be counter-rotated quickly and without impediment, preferably in all directions.

A method and apparatus for construction of a protective head covering (helmet) to be worn by individuals engaged in activity that may, without the apparatus, cause concussive brain injury. The helmet, which is comparable in weight and envelope to conventional helmets, can be constructed from commercially available materials. The design features a dual shell concept where outer shell deflection under load triggers the primary attenuation mechanism. A second more rigid inner shell defines a space where one or more compartmentalized sealed elastomer energy absorbing cells are located. These cells contain either a gas or liquid agent designed to adaptively convert potentially injurious normal impact force energy to energy that is channeled between the shells and therefore harmless to the wearer. A portion of this converted energy will be stored and then utilized to automatically re-set the apparatus for the next impact event.
