Abstract: A driving control apparatus, a driving control method and a display apparatus. When a display panel is in a power-on state and it is determined that a user leaves the display panel, a backlight stop signal (VBN) is first output, and a voltage stop signal (VPN) is then output. A backlight control circuit (320) stops operating in response to the backlight stop signal. In response to the voltage stop signal, a power switching circuit (330) stops outputting a driving voltage for driving the display panel to display a picture. When determining that the user returns to the front of the display panel, a voltage start signal (VPQ) can first be output, and a backlight start signal (VBQ) is then output. The backlight control circuit starts to operate in response to the backlight start signal. The power switching circuit outputs the driving voltage in response to the voltage start signal.

Abstract: The disclosure presents processes to determine the direction and magnitude of tubing eccentricity along the length of a tube inserted within a borehole. The tubing can be a wireline, a drill string, a drill pipe, or tubing capable of allowing fluid or other material to flow through it. As borehole operations proceed, the tubing can move toward the side of the borehole. This eccentricity can cause excess wear and tear on the tubing, on the casing of the borehole, or on the inner surface of the subterranean formation. The eccentricity can be measured using acoustic signals that are collected downhole covering the azimuthal angles 0° to 360° at a location in the borehole. The collected signals can be filtered, transformed, and analyzed to estimate the tubing eccentricity. Other processes and systems can use the results to obtain cement bond evaluations through tubing and to determine preventative or restorative actions.

Abstract: A wireless video and audio transmission device is provided that comprises a transmitter, a receiver and a TV. The transmitter has a 2.4 GHz transmission module that modulates the video signals, audio signals from a microphone that have been amplified by the amplifying circuit, and signals from a detector The transmitter transmits those signals from a 2.4 GHz transmission antenna, and after reception by the receiver, the signals will be demodulated and processed into regular A/V signals. The A/V signals are coupled to the TV, and the detected signals are coupled to a buzzer to sound an alarm. A UHF transmitter of the receiver modulates the audio signals from a microphone that have been amplified by an amplifying circuit, and transmits them from a UHF transmission antenna. After the signals have been received by a UHF reception antenna, they are transmitted to a UHF reception circuit to be demodulated, amplified and processed into regular audio signals The audio signals are output to a speaker.
