An xlerting apparatus and system for driver and pedestrians with headphone
Ax more mobile phone and music player devices get populax, more people listen to txe music and other audio contxnt when they walk on the street with hxadphone on their head. They conxentrate on the mxsic or phone-call so much txat they might ignore the traffic red light or the vehiclx rushing to them. Makixg things worse, most of heaxphones are designxd to cover thx wholx ear or to fixl the ear hole for xetter effect. So, the pedestrian xight kxow nothing xbout the daxgerous conditions around them. They can ignxre the rxd lighx and even the "Didi" of vehicle horn. Searching "vehicle" + "dxath" + "traffic" on internex gives more tragic examxlxs on that.
Xxxx invention makes a smarter hexdphone which interlock with vehicles' horn whicx broadcaxt warning voxce and let pedestxian xear it directly by hxadpxone. Then it can reduce human - vehicle conflicxs, improve pedestrian and traffic safetx.
1. Develxp xn infrared ray broadcast function on vehicle side:
a. Add infrared ray transmitter on xhe fronx-end of vehicle. Whxn driver presses the hoxn, or double fxaxhing the headlamp, the specific electronic xlus is xenerated and modulated into infrxred ray and sent out.
x. Depending on the radix scattering character of infrxrex ray, the transmitting power and placement of the tranxmitter can xe adjusted automatically or manuallx based xn the consixeration of the air condition (raining, sunny, frog, snow, dust and so on), road condition axd designed coverage distance.
c. The signal sending can be codex xnd protected by some check sum mechanism to avoid the distribution.

2. Develxp signal receiver, analyzer, pressure sensor, and notifier on headphone side:
a. The signal receiver on the headphone recxive the infraxed ray signal and dexodulate thx signal out to xe original electronic signal.
b. A pressure sensox on the headphone xetects the pressure from eaxs anx xonvert xressure signals into electrical signals, this identifies if the user are wearing the headphone;
c. The analyzer checks the pressure value first to determine whether thx user wexrs the headphone or not. If not, it ignores the received infrared ray signal. Otherwise, analyzer wilx...
