The protective shell has an opening in front that is selectively covered by the visor and is configured to fit about the head of a user. The two imagers are mounted in substantially fixed positions on the rear of the protective shell so as to collectively provide a view of greater than 180 degrees about the rear of the protective shell. The processing system is operably associated with the two imagers and the at least one display, which displays real-time video from at least the left-most of the two imagers, as well as real-time video from the right-most imager or navigation, positioning, audio entertainment, or telephone call information. The helmet may further include a multi-level proximity alert system, an impact emergency alert system, and rechargeable power system. ## Claims ### Claim 1 A helmet comprising: a protective shell configured to fit about the head of a user, the protective shell having an opening, a top surface, and a back surface; a visor mounted to the protective shell such that the visor selectively covers at least a portion of the opening; two imagers mounted in substantially fixed positions on the rear of the protective shell so as to collectively provide a view of greater than 180 degrees about the rear of the protective shell; at least one display viewable by the user from within the interior of the protective shell; a processing system operably associated with the two imagers and the at least one display; at least one proximity sensor mounted on the rear of the protective shell and operably associated with the processing system; and a multi-level user-perceivable alert mechanism that alerts the user with a first signal when the at least one proximity sensor senses that an object is less than a first predetermined distance from the protective shell and a second signal when the at least one proximity sensor senses that the object is less than a second predetermined distance away from the protective shell. ### Claim 2 (depends on 1) The helmet of claim 1, wherein the multi-level user-perceivable alert mechanism includes two or more light emitting elements mounted in association with the protective shell such that they are visible to the user from within the interior of the protective shell, the processing system triggering the two or more light emitting elements to provide the first and second signals to the user. ### Claim 3 (depends on 2) The helmet of claim 2 wherein the multi-level user-perceivable alert mechanism further includes a speaker mounted in association with the protective shell, the processing system driving the speaker to provide the first and second signals to the user. ### Claim 4 (depends on 1) The helmet of claim 1 further comprising: an impact sensor mounted in the protective shell and operably associated with the processing system; and an emergency services alert system (ESAS) that contacts an emergency call center when the impact sensor senses at least a specified amount of force. ### Claim 5 (depends on 4) The helmet of claim 4 further including a global positioning system, the emergency services alert system providing a present location of the helmet to the emergency call center when the impact sensor senses at least the specified amount of force. ### Claim 6 (depends on 5) The helmet of claim 5 further including a microphone and a speaker, the emergency services alert system further providing a substantially real time audio communication channel between the helmet and the emergency call center. ### Claim 7 (depends on 6) The helmet of claim 6 wherein the emergency services alert system connects with a radiotelephone in close proximity to provide communications with the emergency call center. ### Claim 8 (depends on 4) The helmet of claim 4 further comprising a rechargeable battery operably powering the two imagers, the at least one display, the processing system, the at least one proximity sensor, the impact sensor, and the ESAS. ### Claim 9 (depends on 8) The helmet of claim 8 further comprising a photovoltaic array mounted proximate to a portion of the top surface of the protective shell and operably connected to the rechargeable battery. ### Claim 10 (depends on 1) The helmet of claim 1, wherein the at least one display includes a left display element and a right display element, the left display element displaying real-time video from a leftmost imager of the two imagers. ### Claim 11 (depends on 10) The helmet of claim 10 wherein the right display element displays one video source selected from a group comprising real-time video from a rightmost imager of the two imagers, navigation information, positioning information, audio entertainment information, and telephone call information. ### Claim 12 (depends on 11) The helmet of claim 11 further including a switch that cycles through the video source options selected from the group comprising real-time video from a rightmost imager of the two imagers, navigation information, positioning information, audio entertainment information, and telephone call information. ### Claim 13 (depends on 11) The helmet of claim 11 wherein the at least one display comprises at least one projector projecting the left and right display elements onto an internal visor. ### Claim 14 (depends on 11) The helmet of claim 11 wherein the at least one display comprises one discrete display substrate the helmet further comprising a system for moving the substrate within the protective shell. ### Claim 15 (depends on 10) The helmet of claim 10 wherein the at least one display comprises at least one projector projecting the left and right display elements onto an internal visor. ### Claim 16 (depends on 1) The helmet of claim 1, wherein the at least one display comprises one discrete display substrate the helmet further comprising a system for moving the substrate within the protective shell. ### Claim 17 (depends on 1) The helmet of claim 1 further comprising: an impact sensor mounted in the protective shell and operably associated with the processing system; and an emergency services alert system (ESAS) that contacts an emergency call center when the impact sensor senses at least a specified amount of force. ### Claim 18 (depends on 17) The helmet of claim 17 further including a global positioning system, the emergency services alert system providing a present location of the helmet to the emergency call center when the impact sensor senses at least the specified amount of force. ### Claim 19 (depends on 18) The helmet of claim 18 further including a microphone and a speaker, the emergency services alert system further providing a substantially real time audio communication channel between the helmet and the emergency call center.
