Abstract:
The invention relates to an apparatus for preventing infection by malicious code, comprising: a database in which files installed in an agent system, DNA values for each part of the files, and index information for indicating whether each file is normal or malicious are stored; a calculation unit which calculates a DNA value for a part of a file for which an execution is requested in the agent system; and a file inspection unit which searches the database to extract, in a group, files having the DNA value calculated by the calculation unit, inspects whether an object file is normal or malicious on the basis of the index information on the files extracted in a group, and allows the execution of the object file or makes a request for the calculation of DNA values of other parts which selectively include one part of the object file.
Abstract:
An originating communications device is configured to transmit a text message to a recipient mobile device when the originating device determines that the recipient device has failed to connect with a call that was initiated by the originating device. The text message is designed to indicate that the recipient device has failed to connect with the call; in addition or as an alternative, the text message includes a code that indicates to the recipient device that it is potentially in a poor RF coverage area. The recipient mobile device, upon receiving and displaying the text message, may determine that it is indeed in an area with poor coverage and will in response store its current geographic location as a poor coverage area. Other embodiments are also described and claimed.
Abstract:
An audio player includes an audio headset having two earpieces. A playback circuit provides one of a stereophonic program and a monaural program to the audio headset. The monaural program may be created by mixing channels of the stereophonic program. A mode control is coupled to the playback circuit and to the audio headset. The mode control detects when at least one of the two earpieces is not adjacent a listener's ear and causes the playback circuit to deliver the monaural program to the audio headset.
Abstract:
A refueling apparatus for charging nuclear fuel in a reactor vessel, the refueling apparatus including: a refueling unit loading new nuclear fuel to a core or extracting spent nuclear fuel from the core; and a waveguide sensor unit including an ultrasonic wedge to form a Lamb wave, a waveguide with an end connected to the ultrasonic wedge and with another end transmitting the Lamb wave into the reactor vessel, and an ultrasonic sensor connected to the ultrasonic wedge and sensing a reflection signal reflected from an inside of the reactor vessel, the waveguide being formed in a plate shape and mounted in an end of the refueling unit. The waveguide integrally moves with the refueling unit, and the waveguide sensor unit detects a condition of the inside of the reactor vessel, while the refueling unit refuels the fuel assembly in the reactor vessel.
Abstract:
A power savings mode for data updates is provided. The power savings mode prevents data updates to occur while a screen of a portable electronic device is turned off and the device is in a sleep state. The power savings mode waits until the screen is turned on and the portable electronic device is in a wake state before allowing applications and widgets to update data from network repositories. By preventing applications and widgets from updating data while the portable electronic device is in a sleep state, the power savings mode conserves battery life and network bandwidth by limiting possibly unnecessary data transmissions.
Abstract:
A removable case for a mobile communications device includes an opening that aligns with a microphone port that is built into the device. The case includes a windscreen that is sealed across the opening of the case. The windscreen is designed to reduce wind noise, air blasts, vocal plosives, and other noise. Other embodiments are also described and claimed.
Abstract:
A display device having a reduced repair line length and a reduced repair unit to reduce the wire resistance of the repair line and the repair unit. The display device includes: a single flexible circuit film; a circuit board connected to the flexible circuit film; and a thin film transistor array panel connected to the flexible circuit film and having a display area and a peripheral area enclosing the display area. The display device also includes a single driving circuit chip disposed on the flexible circuit film; a repair line and a repair bar disposed in the peripheral area of the thin film transistor array panel; a repair amplifier disposed on the driving circuit chip and connected to the repair line and the repair bar. A repair input line connects the repair bar and the repair amplifier and a repair output line connects the repair amplifier and the repair line.
Abstract:
A device includes a microphone array fixed to the device. A signal processor produces an audio output using audio beamforming with input from the microphone array. The signal processor aims the beamforming in a selected direction. An orientation sensor—such as a compass, an accelerometer, or an inertial sensor—is coupled to the signal processor. The orientation sensor detects a change in the orientation of the microphone array and provides an orientation signal to the signal processor for adjusting the aim of the beamforming to maintain the selected direction. The device may include a camera that captures an image. An image processor may identify an audio source in the image and provide a signal adjusting the selected direction to follow the audio source. The image processor may receive the orientation signal and adjust the image for changes in the orientation of the camera before tracking movement of the audio source.
Abstract:
A device to provide an audio output includes a microphone array, a signal processor, and a graphic user interface (GUI). The signal processor is coupled to the microphone array to perform audio beamforming with input from the microphone array. The GUI is coupled to the signal processor to display a plurality of audio sources, to receive a selection of at least one of the plurality of audio sources from a user, and to provide the selection to the signal processor for aiming the audio beamforming toward the selected audio source. The selection may be made by touching the display. The device may further include a camera and the GUI may display an image received from the camera as the plurality of audio sources. The camera may provide a moving video image and the signal processor may provide a synchronized audio signal aimed at the selected audio source.
Abstract:
A data driving circuit receiving an image signal and applying a data signal based on the image signal to a display panel, the data driving circuit includes a signal generator that generates a horizontal scanning identical signal based on the image signal and a load signal instructing an output of the data signal to the display panel; a signal amplifier that alternately converts a polarity of an offset compensation value from positive to negative and amplifies the image signal based on the offset compensation value; and a controller that counts pulses of the horizontal scanning identical signal and controls the signal amplifier to retain the converted polarity of the offset compensation value until a counted reaches a predetermined reference value.
