Abstract: Disclosed is an organic light emitting diode, in which the light transmittance of a transparent cathode is improved, and which includes a substrate, a first electrode formed on the substrate, an organic layer formed on the first electrode, a second electrode formed on the organic layer, and a transparent layer formed at either one or both of a position between the organic layer and the second electrode and a position on the upper surface of the second electrode and including any one selected from among an oxide, a nitride, a salt and mixtures thereof, so that the formation of the transparent layer on the cathode results in increased light transmittance and decreased resistance, thereby improving electrical performance of products. A method of manufacturing the organic light emitting diode is also provided.

Abstract: Disclosed is an organic light emitting diode, which has improved light transmittance and which includes a first substrate and a second substrate, a first electrode formed on the first substrate, an organic layer formed on the first electrode, a second electrode formed between the organic layer and the second substrate, and an antireflective layer formed on at least one surface of at least one of the first substrate and the second substrate and having a predetermined refractive index, so that the formation of the antireflective layer on any outer surface of at least one of the first substrate and the second substrate results in increased transmittance, thus improving reliability of products. A method of manufacturing the organic light emitting diode is also provided.

Abstract: A barrel module and an imaging apparatus including the same. The barrel module includes: a base having a surface on which an image pickup device is disposed; a lens barrel disposed on the base; a driver for providing driving power to move the lens barrel up and down over the base; a clip connected to the driver to be disposed between the driver and the lens barrel; and an elastic member for providing elasticity between the lens barrel and the clip, wherein the lens barrel moves from an original position toward the base according to an external force is applied, and when the external force is removed, the lens barrel goes back to the original location due to the elasticity of the elastic member.

Abstract: A lens barrel assembly and a camera including the lens barrel assembly are provided. The lens barrel assembly includes a barrel case accommodating at least one optical lens, and a flexible printed circuit board (FPCB) configured to transmit signals between an area inside of the barrel case and an area outside of the barrel case. The barrel case comprises an outlet slit formed in the barrel case. The outlet slip being configured for extending the flexible printed circuit board to the area outside of the barrel case. Accordingly, the lens barrel assembly has an improved extension structure for extending the flexible printed circuit board which is configured to transmit signals between the inside and the outside of the lens barrel assembly.

Abstract: A cleaning equipment includes a moving module moving a wafer from a first position to a second position, and a cleaning module provided at a third position between the first and second positions and including a plurality of cells, each cell having one or more pairs of outlets and inlets, the outlets for discharging a chemical solution onto the wafer and the inlets for drawings the chemical solution from the wafer, in a movement path of the wafer. The plurality of cells are individually operated.

Abstract: A mind-control toy is provided, comprising one or more biosensors configured to detect brainwave activity and generate signals based on the detected brainwave activity. A controller may be responsive to the signals to direct a member to effect movement of one or more objects. In some embodiments, the member includes a device for suspending the object in midair above the device, and the controller is responsive to the first signal to vary output of the device to control a suspended height of the object. In some such embodiments, the mind-control toy includes an obstacle course defining an aerial path. In other such embodiments, the mind-control toy includes a track along which players can compete or cooperate. In other embodiments, the mind-control toy includes a maze, a portion of which may be rotated using mind control to maneuver the object from a start zone to an end zone.

Abstract: Disclosed is a method for data synchronization in a web-based transmission device management system, in which managing data requiring synchronization between a web server and a client is constructed as a tree data structure, and a change flag for judging a data change is easily set. The web server increases a second event number by a certain degree whenever an event datagram is transmitted to the client, and the client judges whether or not the event datagram is lost by comparing the second event number and a first event number stored by the client whenever an event datagram is transmitted from the web server. If the event datagram is not lost, the client increases the first event number by a certain degree and performs data synchronization using the received event datagram.
