METHOD AND DEVICE TO IDENTIFY A PERIODIC LIGHT SOURCE |
摘要 |
This invention relates generally to devices for location positioning and more particularly relates to a system for identifying an environmental source emitting a base frequency and waveform signal. A sensor (101) records an environmental source (105) emitting a base frequency and waveform signal, the signal being amplified (102), digitized (103), processed and compared (104) with a stored unique waveform characteristic. On the basis of the comparison result(s), location positioning and/or a device orientation may be determined. The invention further relates to a method and a computer readable medium containing a program for making a processor carry out the method. |
