Abstract
A mask is described herein that uses correlated magnets which enable a person to easily secure and remove the mask to and from their head. Some examples of such a mask include a scuba mask, a welding mask, a fencing mask, a goalie mask, a paint mask, a paintball mask, a catcher's mask, a ski mask, a goalie mask, an oxygen mask, a surgical mask, a face shield, a filter mask, a theatrical mask, a costume mask, a continuous positive airway pressure (CPAP) mask.
Claims21
A mask comprising:
- a frame that supports at least one lens, where the frame has a first support with a first end of a strap attached thereto, where the strap has a second end which incorporates a first field emission structure, where the frame has a second support which incorporates a second field emission structure, where the second end of the strap is attached to the second support of the frame when the first and second field emission structures are located next to one another and have a certain alignment with respect to one another, where each of said first and second field emission structures include field emission sources having positions and polarities relating to a desired spatial force function that corresponds to a relative alignment of the first and second field emission structures within a field domain.
A method for using a mask, said method comprising the steps of:
- placing the mask on a head of a person, where the mask includes a frame that supports at least one lens, where the frame has a first support with a first end of a strap attached thereto, where the strap has a second end which incorporates a first field emission structure, where the frame has a second support which incorporates a second field emission structure, and
- pulling the second end of the strap around the head of the person so the first field emission structure interacts with the second field emission structure, where the second end of the strap is attached to the second support of the frame when the first and second field emission structures are located next to one another and have a certain alignment with respect to one another, and where each of said first and second field emission structures include field emission sources having positions and polarities relating to a desired spatial force function that corresponds to a relative alignment of the first and second field emission structures within a field domain.
