Abstract: An embodiment of the present invention embeds image data within a multimedia file including audio information in a manner providing storage capacity tailored to the size of the image. Thus, the resulting file structure for audio content is tailored to incorporate image data, where the image data is an integral part of the file structure. In addition, embedded image data is synchronized with audio information to enable display of the images at specific instances of an audio presentation. Synchronization data is further integrated in the multimedia file, where audio, image and synchronization data are bound together in the same file and format. This allows the file to have any sufficient size and to display and synchronize all desired images with an audio presentation.

Abstract: The invention relates to an apparatus for recycling synthetic leather. The primary object of the invention is to provide an apparatus for recycling synthetic leather which can effectively separate out the resin from the synthetic leather.

Abstract: This invention relates to an apparatus for automatic gas ignition control for igniting an auxiliary fire nozzle and main fire nozzle in a water heater, to precisely, safely and automatically ignite the gas. The apparatus for automatic gas ignition control according to the present invention provides an alarm to give early warning if the unit is not being fed a sufficient amount of gas. Further, this invention provides a gas flow controller to control the flow rate of gas dependent upon the change of water level or pressure requirements. Also this invention provides an electric circuit for igniting the auxiliary fire and the main fire. If any component in the electric circuits is damaged, the circuit will cease to operate or function and no gas will flow. This provides an absolute protection avoiding accidents.
