System and Method for Communication Among Embedded Devices Using Visual Images
First Claim
1. A communication system comprising:
- a signal transmitting device having a sending CPU and a sending memory;
a generated signal template for generating a signal pattern to be transmitted;
a signal display for displaying the signal pattern generated by said generated signal template;
a signal display controller for controlling position and orientation of said signal display;
a signal receiving device for communicating with said signal transmitting device having a receiving memory and a receiving CPU;
a visual recording device for sensing the signal pattern of the signal display;
an image for decoding the signal pattern; and
a visual recording device controller for automatically controlling the orientation and zoom of said visual recording device, wherein communication between said signal transmitting device and said signal receiving device is established by the visual recording device detecting and decoding visual images displayed by the signal display.

Abstract
A system and method for wireless communication among embedded devices using visual images. More specifically, a signal receiving device uses a visual recording device to locate the signal display screen of a signal transmitting device by employing an alternating image detection method. An image decoder embedded in the signal receiving device decodes the signal received by the visual recording device. In addition, a method is employed for automatically controlling the position and orientation of the signal display device and the visual recording device. Advantageously, communication among the embedded devices can be effectuated without the emission of potentially harmful radiation.
