Abstract: An over-the-head face mask is provided with a self-contained microphone, a voice signal modifying device and a speaker for providing a costumed appearance for the individual wearer of the face mask and, in addition, a camouflaging or novelty effect on the wearer's voice. A microphone secured to the face mask is located proximal to the mouth of the wearer and is electrically connected to a voice signal modifier which, in turn, is connected to a speaker. The electrical components are powered by self-contained batteries located within a space provided between the hood portion of the face mask and a fabric liner. The voice signal modifier can amplify or muffle the wearer's voice, shift the frequency of the wearer's voice, produce a monotone voice effect or any other desired camouflaging effect to the wearer's voice. In addition, the face mask can be provided with light bulbs for the fake eyes of the mask.

To this end, the work helmet includes a light-receiving element for receiving a light signal modulated with the guide information, an earphone for reproducing audibly the guide information, a light emitting element for emitting an outgoing light signal modulated with a speech signal supplied from a microphone, and an oscillator for generating a carrier having a frequency specific to the helmet, on which carrier said speech signal is modulated, so that the outgoing light signal is always modulated by the carrier serving as a helmet identifying signal by means of which the central control room can recognize and identify the worker wearing the helmet.

Abstract: The present invention relates to a hard hat which may be collapsed and easily stored when not in use. The hat uses a brim as a structural support, multiple curved segments and means for locking the segments into place. The multiple curved segments have raised and lowered portions, decreasing radii, and a common pivot point on the sides of the brim. In the collapsed position all the segments are stacked on one side of the brim, but when the hat is to be extended, the first curved segment is rotated about the common axis. As it is rotated a lowered portion on the back inner surface of the segment engages a raised portion on the front outer face of the next segment and it is drawn (as are the remaining segment) along with the first segment. Once the first segment has reached its position on the further side of the brim, the first segment is then locked into place and the hat is complete.
