As shown in FIG. 3, in one embodiment of the invention, helmet 100 further comprises impact sensor 150 configured to detect mechanical impact force received by helmet 100 and connected to communication and control device 110.
[0037] In an example, impact sensor 150 is installed just under outer cover of helmet 100, such that impact sensor 150 can do sensing properly. When helmet 100 is hit or struck mechanically, the mechanical impact force can be detected by impact sensor 150.
[0038] In one embodiment of the invention, communication and control device 110 receives the impact detection result from impact sensor 150 then transmits out the impact detection result via any one of a first wireless channel and a second wireless channel.
[0039] In an example, after impact detection result is generated, impact sensor 150 sends it to communication and control device 110. At communication and control device 100, it continuously receives impact detection result from impact sensor 150, then communication and control device 100 can continuously send out the impact detection result via any one of the first or second wireless channel. And, at other end of the wireless channel, a terminal, such as a mobile phone, continuously receives the impact detection result. The terminal can continuously display the impact detection result on its screen. Alternatively, the terminal can continuously display the impact detection result on its screen together with video obtained from the video signal received from helmet 100. Alternatively, communication and control device 110 can continuously embed the impact detection result into video signal which it is going to sends out wirelessly, for example by overlying then impact detection result as a number shown on video image, then when a terminal receiving the video signal displays video derived from the video signal, the impact detection result is automatically shown on the video screen.
[0040] Alternatively, communication and control device 110 may not send out the impact detection result continuously, in contrast, communication and control device 110 sends out the impact detection result through wireless channel only if it is determined that the impact detection result reaches a threshold which can be set as needed. Therefore, once a terminal, such as a mobile phone, receives then impact detection result through wireless channel it can inform related personal to take necessary action for the wearer of helmet 100.
[0041] In one embodiment of the invention, communication and control device 110 instructs earphone 130 to send out audio alarm if the impact detection result reaches a threshold In an example, when communication and control device 110 determines the impact detection result received from impact sensor 150 reach a threshold, it can instruct earphone 130 to send out an audio alarm which can be heard by the wearer of helmet 100 to inform the wearer he or she just get a serious hit on head. This audio alarm can be a mere sound, noise or beeping as those used by a regular clock alarm, or, alternatively, this audio alarm can be a number reading such as "100 pounds" or the like. Alternatively, this audio alarm can be a mere sound followed by a number reading.

[0044] In an example, communication and control device 110 receives the impact detection result from impact sensor 150 then determine whether it reaches a threshold, and alarm means 160 is activated or turned on if the threshold is reached. Wearer of helmet 100 or other appropriate personal can set the threshold in advance.
[0045] In one embodiment of the invention, impact senor 150 comprises one or more of accelerometer, piezo electric sensor and microelectromechanical system (MEMS). In an example, the accelerometer is a 6-axis accelerometer. It should be understood, communication and control device 110 can make good calculation about how much mechanical impact force received by helmet 100 according to acceleration reading provided by the accelerometer.
[0046] FIG. 5 is a block diagram illustrating different parts in the helmet in accordance with some embodiments. As shown in FIG. 5, in one embodiment of the invention, helmet 100 comprises a power connection means 170. A power source separated from helmet 100 can be connected to communication and control device 110 via power connection means 170.
[0047] In an example of the invention, a power source such as a battery is equipped in helmet 100 to supply power to communication and control device 110, then communication and control device 110 can supply power to other electronic components in helmet 100, such as camera 120, microphone 140, and earphone 130. In another example, no power source is equipped in helmet 100, then power connection means 170, such as a power line with a connector (USB connector for example), is provided at helmet 100, such that a separate power source can be connected to communication and control device 110 to supply power via power connection means 170.
[0048] In an example of the invention, a battery pack can be connected to power connection means 170 using USB connector, then the batter pack can be carried by wearer of helmet 100 at other part of his/her body, such as in his backpack or in bag hanging at his/her belt.
[0049] FIG. 6 is a block diagram illustrating different parts in the helmet in accordance with some embodiments. As shown in FIG. 6, in one embodiment of the invention, helmet 100 comprises speed meter 180. Speed meter 180 measures speed of the helmet 100 and send the speed measurement result to communication and control device 110. Communication and control device 110 transmits out the speed measurement result via any one of the first wireless channel and the second wireless channel.
[0050] In an example, after the speed measurement result is generated, speed meter 180 sends it to communication and control device 110. At communication and control device 100, it continuously receives the speed measurement result from speed meter 180, then communication and control device 100 can continuously send out the speed measurement result via any one of
[0051] the first or second wireless channel. And, at other end of the wireless channel, a terminal, such as a mobile phone, continuously receives the speed measurement result. The terminal can continuously display then speed measurement result on its screen. Alternatively, the terminal can continuously display the speed measurement result on its screen together with video obtained from the video signal received from communication and control device 110 of helmet 100. Alternatively, communication and control device 110 can continuously embed the speed measurement result into video signal which it is going to sends out wirelessly, for example by overlying then speed measurement result as a number shown on video image, then when a terminal receiving the video signal displays video derived from the video signal, the speed measurement result is automatically shown on the video screen.
[0052] Alternatively, communication and control device 110 may not send out then speed measurement result continuously, in contrast, communication and control device 110 sends out speed measurement result through wireless channel only if it is determined that the speed measurement result reaches a threshold which can be set as needed. Therefore, once a terminal, such as a mobile phone, receives the speed measurement result through wireless channel it can inform related personal to take necessary actions.
