A multilayer ceramic electronic component includes a ceramic body including a dielectric layer and first and second internal electrodes which face each other with the dielectric layer interposed therebetween. The first and second internal electrodes include a conductive metal and an additive. In a cross-section of the ceramic body in the length-thickness (L-T) plane, a ratio of content of the additive in the first and second internal electrodes in upper and lower portions of the ceramic body to a content of the additive in the first and second internal electrodes in a central portion of the ceramic body is around 0.63 to around 1.03.

Disclosed herein is an apparatus and method for low power local area communication using event signal control. The low power local area communication apparatus includes at least one coordinator and a plurality of network device. The network coordinator transmits a periodic beacon signal based on the preset beacon period of a superframe and a continuous RF event signal, receives a first signal including a Service Set Identifier (SSID) and a second signal including the SSID and an event detection code, and performs the transmission or reception of data when authentication has been completed. Each of the network devices generates and transmits the first and second signals, performs the transmission and reception of data after authentication has been completed, and is thereafter switched to power saving mode or OFF mode. Accordingly, the construction of the system is simplified, and the cost of the system is reduced.

The present invention relates to a variable focus lens including a fluid chamber containing first and second fluids which are non-miscible and have different refractive indices, the fluid chamber having a plurality of protrusions formed along a circumference of one open end thereof. The variable focus lens also includes a transparent plate attached to the open end of the chamber via a sealing with a predetermined interval from the protrusions. The variable focus lens further includes a first electrode disposed inside the chamber to act on the first fluid and a second electrode disposed inside the chamber and is insulated from the first fluid. The invention allows an easy manufacturing process without bubble formation, and eliminates entry and formation of bubbles due to external changes such as in temperature and pressure, thereby allowing good performance of the lens regardless of external environmental changes.

A liquid lens for adjusting a focal length by electro-wetting. A body houses a non-conductive fluid and a conductive fluid therein. A cover is capped on the body. A first adhesive bonds the body to the cover, the first adhesive curing rapidly. Also, a second adhesive bonds an outer periphery of the body to an outer periphery of the cover. The glass cover and the body are bonded across a large area by two types of adhesives with different compositions. This allows the lens manufactured to greatly withstand temperature and heat impact and stay durable in a high-temperature humid environment, thereby significantly elevating a quality of the final product.

Liquid lens having improved sealing structure

A method of fabricating a liquid lens which can prevent unstable movement of liquids while sealing a hole containing the liquids by applying voltage to a chamber containing the liquids to induce electrowetting, and a liquid lens fabricated thereby. The method includes providing a chamber with a hole formed therein for containing liquid and injecting two non-miscible liquids with different refractive indices. The method also includes placing a conductive transparent plate to be in contact with the liquid on the top and applying voltage to the conductive transparent plate and the chamber to induce electrowetting, thereby changing the shape of meniscus between the two liquids. The method further includes covering an upper surface of the chamber with the conductive transparent plate to seal the hole.
