摘要： A personally worn or portable annunciator device for alerting, warning, training, communicating or diagnostic use for people especially those with hearing impairments. This device which can be activated locally or remotely has as one of its means of generating a tactile sensation a transducer or buzzer, as well as a visual light both of which are activated automatically upon the detection of an audio signal substantially above the local ambient noise, or by a RF signal remotely generated by an auxiliary unit.

摘要： The electrical plug guard comprises a disc member having a pair of elongated slots to frictionally receive the prongs of an electrical plug. The slots have centers offset with respect to each other along the length of the slots. The slots are effective to skew the prongs of the plug with respect to each other when the prongs are inserted in slots through the disc member. The disc member has a thickness sufficient to prevent finger contact with the prongs which are electrically active when partially inserted into an electrical plug outlet.
