A method and apparatus for changing a page when an e-book terminal is inclined is provided. The method includes sensing that the e-book terminal is inclined to a left or right side, then changing a current page to a next page when the e-book terminal is inclined to the left side or changing the current page to a previous page when the e-book terminal is inclined to the right side.
Abstract:
A method of controlling a DC/DC converter to regulate an output voltage from an input voltage source that varies from a fully-charged voltage to a discharged voltage. The method introduced improves the dynamic response of the converter during transients by switching between different converter topologies to spread out voltage spikes, which are an inevitable result of transients. The invention also can improve the efficiency of the DC/DC converter by replacing higher loss modes with combination modes.
Abstract:
The present invention relates to a method and system for performing a handover from a serving base station to a target base station. The method for performing handover includes: transmitting a signal for detecting a base station searching signal (BS-SS) from the serving base station to a user equipment, wherein the user equipment receives the signal for detecting the BS-SS and broadcasts the BS-SS to the plurality of base stations; receiving from a target base station a request for the signal for detecting the BS-SS, wherein the target base station is one of the plurality of base stations; transmitting the signal for detecting the BS-SS from the serving base station to the target base station; receiving a receipt signal of the BS-SS from the target base station; identifying the user equipment, which had broadcasted the BS-SS to the plurality of base stations, based on the receipt signal of the BS-SS; and performing a handover from the serving base station to the target base station based on the confirmation of the serving base station.
Abstract:
Disclosed are a method for producing a dialkoxymagnesium support for catalyst for olefin polymerization, a method of producing catalyst for olefin polymerization using the dialkoxymagnesium support and a method of polymerizing olefin using the catalyst. By using the method for producing a support according to the present invention, the content of large particles in the dialkoxymagnesium support can be controlled and the particle can have spherical shape, so the catalyst produced by using the support have high activity and stereoregularity, and high bulk density, thereby making it possible to be applied to the commercial processes.
