     DETAILED DESCRIPTION 
       [0022]      FIG. 1  illustrates various systems  2 . As shown in  FIG. 1  there is a pair of earpieces  10 , which includes a left earpiece  12 A and a right earpiece  12 B. A safety helmet  14  for a motorcyclist who rides a motorcycle  18  is shown. The helmet  14  may be an augmented-reality helmet which includes a display. The  14  helmet may include a battery pack mounted in the helmet at a location corresponding with a base of the motorcyclist&#39;s skull. The helmet  14  may also include one or more cameras such a rear-view camera. The helmet  14  may also include one or more sensors. Also shown in  FIG. 1  is an example of an article of clothing in this case a collar  16  which may include an air bag. As will be discussed later herein, various other types of clothing may include an air bag including jackets, vests or racing suits. In addition, one or more air bags may be located in the motorcycle  18 . 
         [0023]    In operation, the set of earpieces  10  may communicate with the helmet  14 , the motorcycle  18 , and/or the article of clothing  16 . This communication may occur to support any number of functions. For example, sensors within the earpiece(s) may be used to collect information, to process information from sensors in the helmet  14 , clothing  16 , or motorcycle  18 , or to provide information to displays within the helmet  14  or the motorcycle  18 , or to activate an air bag associated with the article of clothing  16 . 
         [0024]      FIG. 2  illustrates the set of earpieces  10  including the left earpiece  12 A with a left earpiece housing  14 A and the right earpiece  12 B with a right earpiece housing  14 B. An external microphone  70 A is present on the left earpiece  12 A and another external microphone  70 B is present on the right earpiece. More than one external earpiece may be present on each earpiece. A touch area  19 A is present on the left earpiece and a touch area  19 B is present on the right earpiece. In operation, a user may control functionality of the earpieces through interacting through the touch interface. This may include tapping on the touch area, swiping across the touch area (with different directionality having potentially different meaning), or holding a finger against the touch area. The touch area may be implemented in any number of ways such as through optical emitters and detectors, capacitive sensing or otherwise. 
         [0025]      FIG. 3  illustrates one example of a block diagram of an earpiece. As shown in  FIG. 3 , the earpiece may include one or more sensors  32 . Examples of sensors may include an air microphone  70 , a bone microphone  71 , an inertial sensor  74 , another inertial sensor  76 , and one or more biometric or physiological sensors  78 . The inertial sensors  74 ,  76  may include accelerometers, gyros, or other types of inertial sensors. The biometric sensors  78  may include any number of different physiological sensors including heart rate monitors, pulse oximeters, temperature sensors, or other type of physiological sensors. An intelligent control system  30  is shown which may comprise one or more processors. A gesture control interface  36  is operatively connected to the intelligent control system  30 . The gesture control interface  36  may include one or more emitters and one or more detectors  84  which are used to sense gestures of a user such as a user tapping, holding, or swiping across a touch area of the earpiece. The sensors may provide for capacitive sensing, infrared sensing, other types of light sensing, or other type of emittance and reception to detect types of gestures performed at a touch surface of the earpiece. The intelligent control system  30  is also operatively connected to one or more speakers  73 , one or more light elements such as LEDs  20 , a memory or storage unit  60 , and one or more transceivers  34 ,  35  which may include a wireless radio transceiver  34  such as may be used for Bluetooth or Bluetooth Low Energy (BLE) communications, or WiFi communications, ultra-wideband, or other type of wireless radio communications such as with other wearable devices, with the motorcycle or other vehicle, with the helmet, with a protection system or otherwise. The transceiver  35  may be a near field magnetic inductance (NFMI) or other type of transceiver which may be used to communicate between earpieces and/or for other purposes as well. 
         [0026]      FIG. 4  illustrates one example of a block diagram for a helmet  14 . The helmet  14  may be an augmented-reality helmet which includes one or more displays  106 . The  14  helmet may include a battery pack  114  mounted in the helmet at a location corresponding with a base of the motorcyclist&#39;s skull. The helmet may include a processor  108  which may be operatively connected to the other electronic components within the helmet including a wireless transceiver  100 , sensors such as microphones, cameras, and inertial sensors  102 , a geolocation receiver  104  such as a GPS receiver, an inductive charger  110 , and an inflator  112 . Sensors of the helmet  14  may be used to sense parameters associated with the environment. The processor(s)  108  may be used to receive a signal from the at least one sensor and determine a probability that a safety incident may occur based upon the at least one feature. This probability may be compared to a threshold and if the threshold is exceeded, information may be displayed on the display  106  or other action may be taken. The helmet may be used for blind spot detection, forward collision alert, rear collision alert, cross-traffic alert, merging-traffic alert, lane departure warning, and traffic sign recognition. 
       Audio Feedback 
       [0027]    The earpieces may provide for audio feedback to a user. Where sensors of the earpiece, of the helmet, of the motorcycle (or other vehicle) sense information, this information or that which can be derived from this sensed information may be conveyed to the driver and/or passenger(s) of the motorcycle or other vehicle through audio. For example, any information present on a display of a helmet may be communicated via audio in addition to being displayed or instead of being displayed. 
         [0028]    It is also contemplated that a helmet may be used to provide any number of different sensors to make available for the earpiece. For example, a helmet may be embedded with a plurality of different microphone sensor elements and audio may be received from all or a subset of these different microphone sensor elements.  FIG. 5  illustrates one example of a helmet  14  where there are a plurality of different microphone elements presents which may be printed on the helmet. It is contemplated that a determination may be made as to which of these different audio streams to access at a time. Thus, for example a single microphone within a particular region may be used. It is noted, that having audio streams from different directions may be used to identify the location of a particular audio source, or provide other information about the environment. 
         [0029]    The earpiece(s) may also provide audio feedback to a user to convey information directly from the motorcycle or motorcycle control system.  FIG. 6  illustrates one example of a simplified motorcycle control system  200  where one or more processors  210  are shown. The processors  210  may be operatively connected to a wireless transceiver  202 , any number of sensors  204 , a geolocation receiver  206 , one or more displays  208 , and one or more inflators  212  associated with one or more air bags, a navigation system  214 , an entertainment system  216  or other systems. Information from the motorcycle may be communicated to the earpieces(s) to provide audio feedback. This may include turn-by-turn navigation based on information from the geolocation receiver  206  or associated navigation system  214 , information from a built-in entertainment system  216 , information for any number of sensors  204  which may be associated with any type of vehicle monitoring or other types of sensor, or other sensors. Some of this information may be the same as what is displayed on one or more displays  208  or alternatively, the information may be different than what is displayed to a user of the motorcycle. 
       Input Pathways 
       [0030]    As described above, the earpiece may have a touch surface for receiving gestural inputs or alternatively, one or more buttons or other manual inputs may be present on the earpiece. However, where a person wearing the earpieces also wears a helmet, the touch surface, manual inputs, or other types of user inputs may no longer be available to the user. The earpiece provides for termination of the input pathway into the device in response to detection of bilateral complete isolation of the touch surface from the person while wearing the device. In particular, the earpiece may sense that there is no connection to the world due to the blockage caused by the helmet. This allows the earpiece to prevent errant input signals which could be quite problematic while at the same time adjusting the input pathway expectations to predict voice control or gesture control input formats. However, the earpiece may determine that a user is wearing a helmet in any number of ways. This may include receiving user input that the user is putting on the helmet such as by a user selecting an activity mode associated with motorcycling. The user may select this input mode in any number of ways including via voice command. The earpiece may infer that the user is or will be putting on a helmet based on contextual information such as by sensor readings just prior to the helmet being put on and after the helmet being put on. For example, where sensors including optical sensors such as emitters and detectors sensor readings will detect light at normal conditions and then a transition to little light conditions due to the helmet. Additional sensor readings may be used to further confirm that the helmet is on. For example, the earpiece may emit an audio signal (audible or inaudible) from one or more of its speakers and then one or more microphones may receive the audio signal and process the audio signal to compare it to the signal transduced. Other types of audio processing may be used as well. For example, the change in environmental sounds with the helmet off and the helmet on. Another method of determination as to whether the helmet is on or off is receiving an active signal from the helmet through a wireless transceiver upon a user powering on a helmet where the helmet is so configured, or determining close proximity of the helmet to the earpiece such as by using a beacon associated with the helmet. Once the earpiece(s) have determined that the user has put on a helmet, the earpiece may then turn off sensors associated with the touch surface to prevent contact between the helmet and the sensors providing undesired input. Similarly, once the helmet has been removed, the sensors associated with the touch area may be re-activated. 
       Charging 
       [0031]    It is known that a helmet may include a battery such as for powering a display, communications or other purposes. Where the earpieces are in close proximity to a helmet, the helmet may be used for inductively charging the batteries of the earpieces. Thus, for example, when it is sensed that a user is wearing the earpieces and the helmet the earpiece may cease receiving user input from the touch surfaces and activate a charging mode. In the charging mode, the earpieces may be in close proximity to contacts on the helmet which allow for inductive transfer of power to thereby charge the battery. Thus, once it is determined that a user has the helmet on, the earpieces may be charged by the helmet of the battery. 
         [0032]    It is further noted, that one way in which the earpieces may detect that the helmet is on and in a proper position is to determine if charge is being transferred from the helmet to the earpieces. If charge is being transferred, then this indicates that the helmet is on and in a sufficiently proper position to allow for power transfer and thus sensors associated with the touch surface of the earpiece may be turned off. Similarly, the earpiece may detect that charge is not being transferred which may indicate that the helmet has been removed. 
       Crash Notification 
       [0033]    Because the earpiece includes inertial sensors, the earpiece may detect motion patterns indicative of a crash. This may be detected by sudden changes in acceleration/deceleration such as those associated with impact. After such changes are detected with one or more inertial sensors, emergency measures may be taken. This may include making a phone call, sending a text message, or otherwise contacting emergency services. Information may be communicated about the location, the driver (or passenger) involved, health related information such as may be detected with one or more biometric or physiological monitors and other information. 
       Protective System 
       [0034]    According to another aspect, the helmet may include a protective system or safety system which may include one or more air bags. For example an air bag may be positioned to deploy from a helmet to protect a user&#39;s face, neck, or other portions of the user&#39;s head. Here, the earpiece may predict that a crash will take place and deploys the protective system prior to impact. A determination that a crash will occur may be performed in various ways. For example, changes in acceleration may indicate that a crash is likely. In addition to information sensed directly with the ear pieces, information from the motorcycle (or other vehicle) or the helmet may be used. 
         [0035]    The motorcycle may be equipped with an air bag. Where the motorcycle is equipped with an air bag, a crash sensor of the motorcycle may be used or instead the inertial sensors of the earpiece may be used to detect a crash. An inflator may be used to emit a gas (such as nitrogen gas, carbon dioxide or other gas) to inflate the air bag nearly instantaneously. 
         [0036]    Alternatively, one or more articles of clothing may be equipped with one or more air bags. For example, a jacket or jumpsuit, or other article of clothing may include an air bag and an inflator. Detection of a crash event with the earpieces may be communicated to the article of clothing to inflate the air bag. For example, the earpieces may be used in conjunction with an airbag collar such as that available from Hövding (Malmö, Sweden) (www.hovding.com). However, where an airbag collar is used, the collar does not need to include sensor electronics instead, it merely needs to be able to receive communications from the earpiece. 
         [0037]    Another example of a jacket or jumpsuit with an air bag is available from Dainese (Italy) (www.dainese.com) under the D-AIR trade mark. Such an article of clothing may be equipped with a receiver or transceiver to receive communications from the earpiece such that the earpiece provides for activating the air bags when a crash event is detected or predicted. Thus instead of having accelerometers, gyroscopes, and GPS present in the clothing this type of electronics may be housed in the earpieces and used by the earpieces. Moreover, the jacket or jumpsuit or article of clothing need not have any user interface at all. For example, battery charge level or gas status may be communicated from the article of clothing to one or more earpieces. 
       Coaching System 
       [0038]    According to another aspect, a coaching system may be provided. The coaching system or training system may assist an inexperienced driver (or any driver) in improving their driving performance. The coaching system may provide feedback via audio to the driver. The audio may include voice instructions regarding when the driver should lean in a particular direction and how much the driver should lean in a particular direction. The amount of lean may be determined through use of the inertial sensor(s) in the earpieces alone or in combination with other inertial sensors present in the helmet, in the motorcycle, or in the clothing of the driver (such as present in driving boots or a jacket or racing suit or elsewhere). The instructions may also include instructions regarding speeding up, slowing down, making turns, changing lanes, avoiding other vehicles, or other instructions associated with safe or proper operation of a motorcycle. 
         [0039]    Therefore various methods, systems, and apparatus have been shown and described herein. Although various embodiments have been shown it is to be understood that numerous variations, options, and alternatives are contemplated. This includes variations in the particular sensors of the earpiece, sensors of the helmet, sensors of the motorcycle, sensors of other articles of clothing or other sensors associated with the driver of the motorcycle. Of course, any number of variations in the structure, functions, and control methodologies are contemplated.
