A weather resistant sound attenuating communications headset of modular construction includes two ear cup modules, a microphone boom module, a head band module, a headband cable module, and a termination cable module. The modular construction allows easy replacement of modules as well as selected components of the modules under field conditions without the need for tools. Replaceable water resistant thin film membranes are employed to provide weather protection as well as hygienic protection for the microphone, speaker and amplification electronics. The thin film membranes which cover areas which come into intimate contact with the wearer are easily replaceable under field conditions. Thus a headset that is shared by more than one user can be hygienically cleansed by simple replacement of the microphone and ear cup membranes.

A single use, hermetically sealing mousetrap has a housing defining an enclosure that contains a killing mechanism which is accessible through a rotatably mounted door controlled by a spring-loaded door opening gear mechanism. Mounted to the bottom of the housing inside the enclosure is a spring-actuated setting axle and setting bar combination that is movable between a tripped position and a set position by manipulation of a setting handle positioned outside the enclosure. When the setting axle is moved to the set position, the door opening gear mechanism causes the door to open while tensioning a torsional door spring. A trip latch and bait pedal are configured to operate together to secure the setting bar in the set position, with subsequent movement of the bait pedal by a mouse serving to release the trip latch. When the trap is thereby triggered, the setting bar moves to the tripped position where it both activates the killing mechanism and releases the door opening gear mechanism. The tensioned door spring then closes the door and the killing mechanism kills the mouse. With the door closed, the enclosure is hermetically sealed with the dead mouse inside and the trap can be disposed of without any contact between the user and the carcass along with any parasites and pathogens associated therewith.
