An apparatus to provide augmented reality includes an image acquisition unit to acquire an image including a target object, a supplementary information acquisition unit to acquire supplementary information, an object recognition unit to recognize the target object from the acquired image, and a candidate nomination unit to generate candidate objects based on the supplementary information. A method for providing augmented reality includes transmitting, at a terminal, an image including a target object or supplementary information of the target object, and location information of the terminal to a server; and determining, at the server, whether the target object is recognized, and generating a list of candidate objects based on the supplementary information, if the target object is not recognized.

Semiconductor devices are provided. Semiconductor devices may include a stack structure including word lines stacked on a substrate, first vertical pillars and second vertical pillars that extend through the stack structure, a first string select line overlapping the first vertical pillars in a plan view, and a second string select line overlapping the second vertical pillars in the plan view and being spaced apart from the first string select line in a first direction. In a plan view, a shortest distance between a side of one of the first vertical pillars and a side of one of the second vertical pillars is less than a shortest distance between a side of the first string select line and a side of the second string select line.

A light guide plate for a surface light source device is provided, which includes an incident surface configured to have light from lamps disposed along a predetermined axis, be incident thereon, an emitting surface configured to have the incident light emitted therefrom, a back surface configured to face the emitting surface, and a plurality of unit cells configured to have microprism patterns engraved thereon and distributed and arranged on the back surface. A crossing angle of a microprism arrangement axis, formed by a ridge direction of the microprism patterns, and of an arrangement axis of the lamps is disposed in an alternate angle. The light guide plate has a high front brightness and an excellent uniformity in brightness and does not have a moire phenomenon. In a backlight unit, the use of optical sheets stacked on the light guide plate can be reduced.

Disclosed are an apparatus and a method for smart energy management by controlling power consumption. Power consumption information is collected from one or more electrical device groups with a smart meter and electrical devices connected through gateways. When the method estimates that the power consumption will be larger than a threshold value, a control command is outputted to a load controller connected through the gateway and power consumption of electrical devices that belong to the electrical device using group is remotely controlled. According to an embodiment of the present invention, an energy company that produces and supplies energy can supply energy depending on a consumer's demand by using current facilities because the present invention can collect remotely energy consumption, analyze energy consumption patterns, and control automatically the energy consumption of electrical devices installed in a customer's area. The consumer who consumes energy can save the energy consumption and the charge of the energy consumption.

An aqueous active material composition, an electrode, and a rechargeable lithium battery including the same, the aqueous active material composition including an active material; a binder; and a water-soluble cellulose mixture, wherein the water-soluble cellulose mixture includes a first cellulose compound having a degree of substitution of about 0.5 to about 0.9 and a second cellulose compound having a degree of substitution of about 1.1 to about 1.5.
摘要:
A terminal device stores augmented reality generated by merging an image of an object and attribute information associated with the object. The terminal device, and a method therefor, allow for retrieval of stored augmented reality information about selected objects if the terminal is no longer at a location where the object's image was captured. The terminal device obtains a preference level for the attribute information and displays the attribute information based on the preference levels. Based on usage of the attribute information, the terminal redetermines preference levels for the attribute information. If previously stored augmented reality is requested, the terminal displays the previously stored augmented reality based on the redetermined preference levels.
