Abstract: A light emitting device, including a substrate, a light guiding element, multiple light sources, and multiple reflecting films. The light guiding element is disposed on the substrate and has multiple through holes. The light sources are disposed on the substrate and are respectively disposed in the through holes. The reflecting films respectively overlap with the light sources.

Abstract: A vibration ring includes a vibration module and a latex ring. The vibration module is provided with at least a battery, a circuit board and a vibration motor that are connected electrically in a spherical shell, along with a switch that is exposed out of the shell. The latex ring includes an annular wearing part that is processed with latex, and a spherical vibration part that encloses the shell of the vibration module. The spherical vibration part and the enclosed vibration module act onto a female's clitoris without pressing on other parts of the body, so as to increase the comfortableness in wearing the vibration ring and form a better exciting effect in vibration.

Abstract: The present polymeric materials can be patterned with relatively low photo-exposure energies and are thermally stable, mechanically robust, resist water penetration, and show good adhesion to metal oxides, metals, metal alloys, as well as organic materials. In addition, these polymeric materials can be solution-processed (e.g., by spin-coating), and can exhibit good chemical (e.g., solvent and etchant) resistance in the cured form.
