Abstract

A detachable radar unit for a motorcycle unit is presented. An outer shell is permanently attached to the side of a motorcycle helmet. A radar sensing unit may be inserted into the shell, making electrical contact with a microphone and light panel attached to the helmet. The radar sensing unit may also be detached from the helmet and attached to a car or boat by using separate shells permanently mounted on the car or boat. A special quick disconnect plug in the unit'"'"'s power supply cord is provided which quickly and easily disconnects the helment from the motorcycle should the need arise.

Claims

1. A detachable radar sensing device for a standard motorcycle helmet, comprising:

(1) an aerodynamically curved outer shell including attaching means comprising small self-tapping screws and a self-adhesive backing so that the structural integrity of said helmet is maintained wherein said shell may be attached to said helmet;

(2) a radar sensing unit mechanically and electrically detachably connected inside said shell, wherein said electrical connecting means comprises corresponding contacts on said shell and said radar sensing unit such that insertion of said radar sensing unit into said shell establishes the electrical contact;

(3) a light panel attached to said helmet and electrically connected to said radar sensing unit by a wire, wherein said wire is secured to said helmet by means of wire guides having barbed ends;

(4) a microphone attached to said helmet and electrically connected to said radar unit by a wire, wherein said wire is secured to said helmet by means of wire guides having barbed ends; and

(5) a quickly detachable power cord, said power cord having an upper end attached to said outer shell and is releasably attached to the wearer of said helmet by means of an alligator clip and a lower end connected to the power source of a motorcycle, further comprising a male-female quick disconnect plug to releasably connect said upper and lower power cord ends;

wherein ia radar unit may be detachably installed on a standard motorcycle helmet and whereby said radar unit is quickly and safely disconnected in case of an accident.
