Abstract:
An LED package includes a housing, a substrate, a pad frame and an LED chip. The housing includes a plastic material, and has a recess with an opening at a top of the housing. The substrate includes substantially the same material with the housing. The pad frame includes conductive material, and is inserted on the substrate, and is fixed between the housing and the substrate. The LED chip is mounted on the pad frame and is disposed at a center of the recess. The housing is protruded and extended to a lower portion of the LED chip. Thicknesses of the housing's sidewalls facing to each other through the recess are substantially the same with each other.
Abstract:
A mobile communications terminal and a method for preventing an input error of a key input unit are provided. The mobile communications terminal includes a touch sensor unit for sensing a key that is input by touching a keypad region in order to output a key input signal corresponding to the key and a controller adapted to determine a key input according to either a priority between multiple keys from which key signals are received or whether a received key signal was generated inadvertently.
Abstract:
Disclosed herein is mobile middleware, a context monitoring method, a context-aware system, and a context-aware service provision method, which support energy-efficient context monitoring. The mobile middleware receives a request for a CMQ from context-aware application programs, receives sensor data from sensors, monitors whether the CMQ is satisfied, and transmits an event to the context-aware application programs according to results of the monitoring. In this case, the mobile middleware controls the sensors so that only sensor data required to determine whether the CMQ is satisfied needs to be transmitted so as to reduce energy consumption during the performance of the monitoring. Therefore, the mobile middleware can perform energy-efficient context monitoring, required by the context-aware application programs.

Abstract:
A compatible optical pickup including an active compensation device to actively switch an angle of incidence of the light on the objective lens when either a third information storage medium that has a different format than that of the first and second information storage media, or the second information storage medium is adopted for use in a data recording/reproducing operation. The active compensation device includes a plurality of transparent substrates, and at least one material layer, interposed between the plurality of substrates, having a refractive index which is actively switched according to an applied voltage. A holographic pattern, formed adjacent to the material layer on a surface of at least one of the transparent substrates, changes a divergence angle of the light by diffracting or transmitting without diffraction the incident light according to change of the refractive index of the material layer. The voltage applied to the material layer is adjusted according to the applied information storage medium that is adopted for the use in the data recording/reproducing operation.
Abstract:
A mobile terminal and an operating method of the mobile terminal are provided. The mobile terminal may be coupled, either wirelessly or by wire, to an external terminal and the mobile terminal may thus receive sync data including information regarding a webpage currently being displayed by the external terminal from the external terminal or a server. The mobile terminal may display the same webpage as is currently being displayed by the external terminal based on the received sync data.
Abstract:
A mobile apparatus includes a processing planner and a plan processor. The processing planner generates a plurality of resource use plans in response to a context monitoring query (CMQ) of an application, and selects a final plan satisfying a request of the CMQ among the resource use plans. The plan processor executes the final plan. Accordingly, the mobile apparatus may support resource-efficient context monitoring.
Abstract:
An image stabilizer that compensates for external vibrations by moving an imaging unit. The image stabilizer includes a first frame on which an imaging unit is installed, a second frame that is connected to the first frame using three points and guides movement of the first frame in a first direction and second direction, and a third frame that is connected to the second frame using three points and guides the first frame and the second frame to move in a third direction and fourth direction, which are perpendicular to the first and second directions.
