  • Publication number: 20180003042
    Abstract: A method for recovering data from a downhole tool in a wellbore includes measuring an electromagnetic signal using first and second sensors. At least a portion of the electromagnetic signal is transmitted by a downhole tool positioned in a first wellbore. The first and second sensors are each positioned at a different location along a length of a second wellbore. The electromagnetic signal measured by the first and second sensors is decoded to recover a property measured by the downhole tool.

  • Publication number: 20170302265
    Abstract: The present disclosure relates to a method of electrically aging a PMOS thin film transistor. The method includes applying a first voltage Vg with an amplitude of A volts to a gate of the PMOS thin film transistor; applying a second voltage Vs with an amplitude of (A-40) to (A-8) volts to a source of the PMOS thin film transistor; and applying a third voltage Vd with an amplitude of (A-80) to (A-16) volts to a drain of the PMOS thin film transistor. Application of the first voltage Vg, the second voltage Vs and the third voltage Vd is maintained for a predetermined time period, and Vd?Vs<0. In this way, reduction of a leakage current of the PMOS thin film transistor is achieved without changing a structural design of the thin film transistor.

  • Publication number: 20170217571
    Abstract: Aerial vehicles are provided with one or more transformable arms (110, 310, 410, 510, 910). The one or more transformable arms (110, 310, 410, 510, 910) may support one or more propulsion units, and transform between a flight configuration where the propulsion units of the arms effect flight of the aerial vehicle, and a landing configuration, wherein the transformable arms (110, 310, 410, 510, 910) are used as a landing support that bears weight of the aerial vehicle when the aerial vehicle is not in flight. Using the transformable arms (110, 310, 410, 510, 910) as legs when the UAV is in a landed state permits the UAV to reduce weight and reduce obstruction to a payload carried by the UAV when the UA is in flight.

  • Patent number: 9722214
    Abstract: The present invention provides an OLED panel and a method for fabricating the same, a screen printing plate, and a display device. The method comprises: forming an OLED mother board, wherein supporting adhesive is formed between an upper base plate and a lower base plate of the OLED mother board, and said supporting adhesive is located below a cutting line; and cutting said OLED mother board along said cutting line to obtain OLED panels. In the fabricating method of the present invention, when the OLED mother board is cut by a cutter wheel, the upper and lower base plate of the OLED mother board is subject to small deformation due to support of the supporting adhesive. As a result, travelling accuracy of the cutter wheel is improved, the distance between the cutting line and packaging adhesive is greatly reduced, and the frame width of the fabricated OLED panel is far less than that of an OLED panel fabricated by a conventional method.
