Abstract:
PURPOSE: A frequency oscillating circuit of an auto attendant device is provided to prevent a duplication and an omission of a word due to a difference between a recoding speed and a reproducing speed. CONSTITUTION: The frequency oscillating circuit of an auto attendant device includes a first port(11) for recording and a second port(12) for reproducing. The first port(11) includes a first oscillating circuit(21). The first oscillating circuit(21) provides a frequency to the second port(12). The frequency oscillating circuit has a signal path which couples a clock output terminal of the first port(11) with an input clock terminal of the second port(12). The second port(12) shares with the first oscillating circuit(21) of the first port(11). A coupling capacitor is formed at a connecting path between the clock output terminal of the first port(11) and the clock input terminal of the second port(12).
Abstract:
The present invention relates to a bean operating apparatus and method for adaptively performing a beam operation in consideration of an analog beam operation environment and a service request for a terminal based on a round robbin mode in an analog beam operating apparatus for transmitting and receiving a signal in a frame unit of a structure for supporting a time division multiple mode by using a hybrid beamforming structure having the number of digital chains in a digital stage less than the number of the antennas in an analog stage. For this, analog beam is changed for a device on the other side which approves the use of the next frame when receiving a request for the use of the next frame from at least one device. Information about that the analog beam is changed for the next frame to be used by the device on the other side is transmitted to a plurality of devices.
Abstract:
A keypad foot printing method and apparatus in a mobile terminal are provided to illuminate or blink a pressed key in a different color to user recognition. A controller of a mobile terminal checks whether a keypad foot print mode has been set in a standby mode in order to use keypad foot printing(401,403,405). When a key of a key input unit is pressed long(407), the mobile terminal is change to a speed dial mode(409) and the controller fetches a phone number from a memory and displays it(411). When a call key is pressed(433), the controller performs dialing to call the other party(413). When the mobile terminal has been set such that keys blink in the pressed order(414), an LED starts to blink in the pressed order(415). The controller turns on an internal timer(419) and checks a time period during which the LED blinks or illuminated(421). When the counted time lapses, the controller turns off the timer and the LED(423).

Abstract:
The present invention relates to a method of setting an analog beam forming coefficient and a device for supporting the same. A method for controlling an antenna in a base station according to an embodiment of the present invention is configured to comprise the steps of measuring an n-th received signal strength with respect to an n-th phase of at least one received antenna; measuring an n+1 th received signal strength with respect to an n+1 th phase to randomly change the n phase forward or backward; and comparing the received signal strength to set the beam forming coefficient to the phase having the maximum received signal strength. According to the present invention, the method enables to set the beam forming coefficient suitable for general cellular environments using multiple analog array antennas without an overhead associated with channel estimation.
