Abstract: An electronic device is provided. The electronic device includes a plurality of microphones, a memory configured to store a first specified time set to form a beam in a first direction using the plurality of microphones, and a processor connected to the plurality of microphones and configured to receive a sound using the plurality of microphones, determine a direction corresponding to the received sound, and if the direction is equivalent to a second direction, associate a second specified time to the received sound as if a beam is formed in the second direction using the plurality of microphones.

Abstract: A method, device, a non-transitory computer-readable recording medium for controlling a voice signal by an electronic device including a first microphone, a second microphone, a communication interface, and a processor are provided. The method includes acquiring a first voice signal by using the first microphone; acquiring a second voice signal by using the second microphone; confirming a telephone call mode for performing, by the electronic device, a telephone call with an external electronic device; adjusting a first output attribute corresponding to the first voice signal or a second output attribute corresponding to the second voice signal, based on the telephone call mode; and transmitting the adjusted first voice signal or the adjusted second voice signal to the external electronic device by using the communication interface.

Abstract: An electronic device is provided. The electronic includes a camera module and a processor configured to capture at least one image of an object using the camera module, obtain a sound using a microphone operably connected to the processor when the at least one image is captured, determine whether the sound is related to the object, when the sound is determined to be unrelated to the object, change at least one attribute of the sound and store the changed at least one attribute of the sound.

Abstract: The present invention cloned a cDNA clone encoding isopentenyl diphosphate (hereafter “IPP”) isomerase (EC 5.3.3.2) from a cDNA library of Hevea brasiliensis latex. The clone has a continuous open reading frame encoding a peptide of 234 amino acids with a predicted molecular mass of 26.7 kDa. The deduced protein is acidic with an isoelectric point of 4.7 and shows high sequence identity with other IPP isomerases. The recombinant protein expressed in Escherichia coli showed IPP isomerase activity. In vitro rubber biosynthesis assays using washed rubber particle (WRP) deprived of initiating allylic diphosphates were performed with the addition of IPP isomerase in the reaction mixture. Results revealed that the recombinant IPP isomerase is catalytically active in catalyzing the conversion of IPP to DMAPP, a key activation step of the basic five-carbon isoprene unit in rubber biosynthesis. Southern analysis indicated that the IPP isomerase is encoded by two genes in Hevea rubber tree.

Abstract: A multi-television broadcasting signal receiving apparatus and method thereof are provided. In the apparatus, if aerially transmitted several television broadcasting signals are tuned and the tuned signal is inputted as an IF signal, a microcomputer outputs a different chrominance control signal according to the broadcasting system by using the input IF signal. A chrominance signal amplifying portion varies a color concentration of a detected signal according to the broadcasting system by the chrominance control signal output from the microcomputer so as to discriminate the broadcasting system. The color concentration is automatically corrected without the need of an extra correction circuit by correcting the color concentration of the broadcasting signal discriminated by a preprogrammed different gain according to the broadcasting system of the received signal. This effect can be applied to a television for receiving a plurality of broadcasting signals.

Abstract: A background-picture compensating circuit using an OSD signal for performing a half tone function without requiring a half tone circuit includes a video signal processor for separating a received composite video signal into R, G, B signals, a microcomputer for muting the R, G, B outputs of the video signal processor upon the receipt of an OSD character display key input to supply a signal for a background picture of the OSD character, and a CRT driver for amplifying respective R, G, B signals from the video signal processor or microcomputer to provide the amplified signals to a cathode of a CRT, in which the microcomputer supplies pulses of a high frequency in response to an input of the signal for the background picture of the OSD character to swiftly repeat On/Off operation of the output of the R, G, B signals of the video signal processor on the background picture of the OSD character for making the background picture level lower than a surrounding level, thereby enabling a display of both an original pict

Abstract: A method and device for displaying a back-screen in a video signal processing system does not require a separate back-screen generating circuit in order to display the back-screen. Instead, an on-screen signal for indicating characters is used to display the back-screen. A determination signal is detected to determine whether a video signal input is received, and if the input video signal is not received, a microcomputer generates an extended on-screen signal to display the back-screen. If the video signal input is detected during display of the back-screen, the extended on-screen signal is blocked, stopping display of the back-screen.
