Architecture and designs of wearable devices for viewing multimedia in 3D are described. According to one aspect of the present invention, a display device is made in form of a pair of glasses. A separate enclosure is provided to generate content for display on the glasses. The content is optically picked up by an optical cable and transported by one or more optical fibers in the optical cable to the glasses, where an image polarizer, deposed on or included in the bridge of the glasses, receives the content and produces an alternating polarized content sequence.

A pillow includes: a body having a filler, consisting of bundles of fibers, filled inside a covering having a space therein; a printed pattern formed on the upper surface of the covering; and a light-emitting means which is installed in the body and which emits light towards the covering, on which the printed pattern is formed, so as to allow the printed pattern to produce an aesthetic effect.

A cooking appliance including a cooking cavity defined by a cooking cavity wall; a cut out provided in the cooking cavity wall; a cooking appliance light arranged in the cut out and configured to illuminate the cooking cavity; and a support plate including a receiving opening for the cooking appliance light, wherein the cooking appliance light is supported in the receiving opening, wherein the support plate fixes the cooking appliance light in the cut out, wherein the support plate including the cooking appliance light closes the cut out in the cooking cavity wall, wherein the cooking appliance light includes a LED illuminant and a light conductor rod, wherein the light conductor rod is supported in the cut out in the cooking cavity wall.

A lighting emblem assembly according to an embodiment of the present invention may include a cover having an installation region surrounded by an inner sidewall and including a light opening formed to pass through the installation region, an inner cover installed in the installation region and including an installation groove, and a lighting module which is installed in the installation groove, is connected to an external power source using a cable connected to a connector, and emits light to an outside through the light opening. The cable may extend between the inner cover and the inner sidewall to an upper end portion of the inner sidewall, and in a state in which the connector extends to an outside of the installation region, a root portion connected to the connector of the cable may be fixedly restricted by a fixing part provided on the inner cover.

An applicator for beauty products comprises a lighting device for providing lighting when applying beauty products. In various embodiments, the lighting device is a hollow body enclosing a power supply, such as one or more batteries, with the power supply and including a light source. The light source is surrounded by an opaque body so the light source casts an even glow of light. Further, the light source has in such a shape or an orientation allowing the light source to emit beyond an outer perimeter of one or more interchangeable brush heads that are coupled to an outer circumference of the light source. The hollow body also includes a switch coupled to the power supply and to the light source. When activated, the switch completes a circuit providing power from the power supply to the light source, causing the light source to emit light.

Four dimensional (4D) energy-field package assembly for projecting energy fields according to a 4D coordinate function. The 4D energy-field package assembly includes an energy-source system having energy sources capable of providing energy to energy locations, and energy waveguides for directing energy from the energy locations from one side of the energy waveguide to another side of the energy waveguide along energy propagation paths.

A cylindrical electrode module of a fiber optic laser system includes an inner cylinder having an inner repeating pattern of longitudinally-aligned positive and negative electrodes on an outer surface of the inner cylinder. The cylindrical electrode mode includes an outer cylinder that encloses the inner cylinder. The outer cylinder that has an outer repeating pattern of longitudinally-aligned negative and positive electrodes on an inner surface of the inner cylinder that are in corresponding and complementary, parallel alignment with the positive and negative electrodes of the inner repeating pattern on the outer surface of the inner cylinder. The cylindrical electrode module includes an optical fiber having an input end configured to align with and be optically coupled to a pump laser. The optical fiber is wrapped around the inner cylinder within the outer cylinder to form a cylindrical fiber assembly. The electrodes are activated to achieve quasi-phase matching.
