  • the elements 101a, 101b function as a means for keeping the mask 100 in a folded or compact state and also function as the mechanism for detecting the folding state of the mask 100. Hence, additional components to keep the mask closed are not required.
  • Such magnetic elements can also be easily integrated in the mask material.
  • a folding line 120 e.g. stitching lines, that allow easy folding is advantageous as it allows easy alignment of the two elements.
  • a folded mask 100 is illustrated in FIG 4 . It is illustrated that the elements 101 coincide when the mask 100 is folded thereby touching or being coupled to each other or being present adjacent to each other.
  • the mechanism is foldable or bendable.
  • the mechanism is located in the mask such that when the mask is folded, for example on the folding or stitching line, the mechanism folds or bends. When the mechanism folds or bends, electric power of the mask is switched off. Alternatively or optionally, when the mechanism is unfolded or un-bended, electric power of the mask is switched on.
  • An implementation of such a mechanism may comprise a light source coupled to a waveguide whereby it is detected when light transmitted through the waveguide exits the waveguide when the waveguide is bended.
  • the waveguide is located in the mask such that when the mask is folded, the waveguide bends. When light exits the waveguide, power is shut down as this means that the mask is folded. When light does not exit the waveguide, power may be activated as this means that the mask is unfolded.
  • the mechanism may also comprise a material that is not electrically conductive when bended, thus when the mask is folded.
  • the mechanism comprises a sensor for determining a folding state of the mask.
  • the mechanism maybe a light sensor located in the mask such that when the mask is folded, the light sensor is covered with the material of the mask.
  • the mask is manufactured such that when the mask is folded, the material of the mask covers the sensor.
  • electric power is switched off as this means that the mask is folded.
  • a controller may be coupled to the sensor and to the power supply to perform this control of the power of the mask.
  • a proximity sensor capable of sensing nearby material of the mask may be used.
  • a sensing mechanism may be used whereby a sensor detects whether a detectable element is detected or in close proximity to the sensor. When detected, the mask can be considered in a folded state and power can be shut off. When not detected, the mask can be considered in an unfolded state and power could be activated.
  • a method 200 for controlling a power supply of an electric power mask as presented in the first aspect comprises: determining whether a mask is folded or unfolded 201; if the mask is folded, switch the power supply off 202. Alternatively or optionally, if the mask is unfolded, switch the power supply on 203. Determining whether the mask is folded or not may be performed by checking whether two elements in the mask are joined together or not, as described above. Alternatively, it may be done by checking whether detected light is above or below a certain threshold when the mask is folded as described above. It may also be done by checking whether the mechanism in the mask is folded or not. Any of the techniques described in the first aspect of the invention may be used in the method to control the power supply of the mask.
