Abstract

Electronic systems generally use light emitting diode (LED) display devices to provide users with information about the internal state of the system. However, the information offered by current methods are always abstract and elusive to average people. The idea here is to use the already existed light-emitting devices, cooperating with intelligent mobile devices which have camera inside, to provide users with detail and human-readable information inside system.

An Information Receiving Method based on Light

An Information Receiving Method based on Light-

Electronic systems generally use light emitting diode (LED) display devices to provide a user with information about the internal state of the system. It's useful when some error occurred and no outside means can access the system. The information offered by current methods are always abstract and elusive to average people, which may panic users by any LED state change.

Some improvements have been made to address this issue. One is use predefined code to express some information, user can get detail by looking up a guide book. By this way, the information can be output is predefined, and quite inconvenient for field support. Another common method is using programmable LED array or LCD to display internal information by text, but it adds up the manufacture cost, also limited messages can be shown based on it's size. On the other hand, any redesign on hardware circuit will not solve the trouble for huge amount of existed systems.

The idea here is to use the already existed light-emitting devices, cooperating with intelligent mobile devices which have camera inside, to provide users with detail and human-readable information inside system.

Electronic systems can control several light emitting devices to blink similarly as voltage level high/low at a frequency, then intelligent devices use camera to capture light status timely, translate them into bit stream, and finally decode and display to user as readable text.

Using this invention, no hardware redesign is needed. What necessary is to add a piece of program to control the light-emitting device status, also an application running on intelligent m...
