Abstract:
This patent relates to a mobile terminal and a method of controlling an operation of the same. The method of controlling an operation of a mobile terminal includes displaying a file list and scroll arrows for scrolling the file list on a touch screen. When the scroll arrow is touched and entered, the file list is scrolled at a scroll speed previously set in response to a time when the scroll arrow is touched and entered. A vibration signal to identify at least one of a scroll speed and a current scrolling position of the file list is provided. Accordingly, when a file list is scrolled, a scroll speed or a current scrolling position can be easily identified by a tactile sense.
Abstract:
A method and system for providing an emergency service are provided. The method includes broadcasting a channel message by a first mobile terminal in a no service state in response to a request for an emergency service, transmitting a corresponding response message to the first mobile terminal when a second mobile terminal receives the channel message from the first mobile terminal, forming a channel between the first mobile terminal and the second mobile terminal, and performing a communication according to the emergency service between the first mobile terminal and the second mobile terminal by using the formed channel.
Abstract:
A method of Dirty Paper Coding DPC using nested lattices is disclosed. The complexity of DPC can be reduced by scaling nested lattices and mapping interference to a lattice point of the scaled lattice.
Abstract:
The present invention relates to efficient handover processing for a multi-mode mobile station supporting a licensed wireless system and unlicensed wireless system. A handover processing method using unlicensed mobile access (UMA) includes: checking, upon recognition of necessity of handover, neighbor cell information from a licensed wireless system; determining possibility of handover on the basis of the neighbor cell information; preventing, if handover is not possible, a handover-related operation, and maintaining an existing connection to the licensed wireless system; and performing, if handover is possible, handover to an associated unlicensed wireless system.

The drone may include: a fuselage in which a battery is mounted and a forward direction is set in an x-axis; a plurality of rotors disposed around the fuselage in four or more, each rotational axis of which is aligned in a z-axis direction; an x-axis tilting mechanism unit formed to tilt the plurality of rotors about an axis parallel to the x-axis; a y-axis tilting mechanism unit formed to tilt the plurality of rotors about an axis parallel to the y-axis; a first drive motor unit driving the y-axis tilting mechanism unit; a second drive motor unit guiding the x-axis tilting mechanism unit; and a control unit configured to implement a plurality of flight modes by controlling the first rotor, the second rotor, the third rotor, the fourth rotor, the first drive motor unit, and the second drive motor unit.
Abstract:
A light emitting device (LED) package and a manufacturing method thereof are provided. The LED package includes an LED including a first electrode pad and a second electrode pad disposed on one surface thereof; a bonding insulating pattern layer configured to expose the first electrode pad and the second electrode pad; a substrate including a via hole bored from a first surface to a second surface and a wiring metal layer formed on an inner surface of the via hole to extend to a part of the second surface; and a bonding metal pattern layer bonded to the wiring metal layer exposed through the via hole at the first surface of the substrate and also bonded to the first electrode pad and the second electrode pad.
Abstract:
Methods and mobile devices for providing various eco-friendly User Interfaces (UIs) are provided. In one method for providing the eco-friendly UI, the mobile device measures a recharging amount or time, displays the recharging amount or time, and determines whether the recharging amount or time is more than a predefined critical amount or time. If the recharging amount or time is more than the critical amount or time, the mobile device is transitioned into an executable state of a specific application. This may give a user motivation to use a solar charge system and thereby reduce battery consumption of the mobile device.
Abstract:
A network scanning method in a mobile station and the mobile station using the method are disclosed, which can efficiently scan a network intended to be selected. The method includes: requesting a network selection, and scanning frequencies in an order starting from the highest receive-level of each frequency; detecting a carrier having network information during the scanning, and acquiring the network information; and sorting carrier frequencies and non-carrier frequencies of respective networks, based on the acquired network information. The frequency scanning is performed only for carrier frequencies. Therefore, corresponding services are provided rapidly to users.

Abstract:
Provided is a mutant of propionyl-CoA transferase from Clostridium propionicum that can convert lactate into lactyl-CoA with high efficiency in a method of preparing a polylactate (PLA) or PLA copolymer using microorganisms. Unlike conventional propionyl-CoA transferase which is weakly expressed in E. coli, when a mutant of propiony-CoA transferase from Clostridium propionicum is introduced into recombinant E. coli, lactyl-CoA can be supplied very smoothly, thereby enabling highly efficient preparation of polylactate (PLA) and PLA copolymer.
