This paper provided an endoscopic oral observation devices, which combines with IR LED (Infrared Rays Light Emitting Diode) and IR CCD (Charge Coupled Device) image sensor to transfer the images to such monitors as television, computers and other media in order to know the situation immediately. While providing user-friendly software interface, allow the users to more easily observe the situation inside the mouth and save the file for the next patient, and even discuss their problems and the improvement progress with the dentist based on the images. The combination of special coated glass and flexible structured CCD observation pen can replace the traditional mouth mirror used by the dentist; in addition, the user can monitor the oral health under the insufficient light condition.

Modulation And Demodulation

In this paper, an online to offline (O2O) method based on visible light communication (VLC) is proposed, which is different from the traditional VLC with modulation and demodulation. It is a new VLC with modulation and recognition. We use RGB light emitting diode (RGB-LED) as the transmitter, and use Pulse Width Modulation (PWM) to modulate the signal to make it flicker at high frequency. Therefore, several features are created. At the receiver, the complementary metal-oxide-semiconductor (CMOS) image sensor is applied to our system to capture LED images with stripes. A convolution neural network (CNN) is then introduced in our system as a classifier. By offline training for the classifiers and online recognition of LED-ID, the scheme proposed could improve the speed of LED-ID (the unique identification of each different LED) identification and improve the robustness of the system. This is the first application of CNN in the field of VLC.

Trapping Devices

A capture-status alarm system was developed to be used in conjunction with a humane snare device used for control of wild canids in Victoria. The alarm unit transmits a unique identity code as well as indicating the capture status of the snare. Large numbers of alarm units can be allocated to a single frequency as data transmission is short and governed by a pseudo-random timer. All status information is presented in alphanumeric format on a light-emitting diode display. The system is user-friendly and does not demand a high degree of skill to operate. The alarm can be incorporated with a number of trapping devices and should enhance the efficacy and humaneness of any trapping operations.
