  • Publication number: 20200321029
    Abstract: A video production method and apparatus, a storage medium, and a computer device are disclosed. The method includes: receiving a follow-shot instruction in a case that reference video content is played on a video play interface, the follow-shot instruction including a reference video identifier; displaying a first video display region and a second video display region on a terminal screen; playing the reference video content in the first video display region, and recording displayed real-time video content in the second video display region; and generating a target video based on the recorded real-time video content and the reference video content. The first video display region and the second video display region are displayed on the terminal screen, the reference video content is played in the first video display region, and the displayed real-time video content is recorded in the second video display region.

  • Publication number: 20190162638
    Abstract: Described herein are passive samplers, making of such samplers, and methods of use. In an example embodiment, a passive sampling membrane comprises, for example, a continuous mesoporous sequestration media having a sequestration phase and a support membrane configured to support the sequestration phase. The sequestration phase may include a hydrophobic region and a hydrophilic region. The continuous mesoporous sequestration media may be configured to simultaneously sequester polar and non-polar organic substances.

  • Patent number: 7517693
    Abstract: A method of determining a molecular descriptor of absorption for a candidate compound is disclosed. The method includes: providing a test solution comprising one or more candidate compounds; contacting the test solution with a simulated biological membrane to partition the one or more candidate compounds into the membrane detecting the presence or amount of the one or more candidate compound in the membrane at one or more permeation times; and determining a molecular descriptor of absorption using the presence or amount of the one or more candidate compound in the membrane at the one or more permeation times. In one aspect the invention provides a skin-imitating membrane, and one or more percutaneous absorption parameters are determined. In another aspect the membrane is disposed on a fiber. In another aspect the test solution is contacted with two or more simulated biological membranes to partition the one or more candidate compounds into the membranes.

  • Publication number: 20030116380
    Abstract: The present invention is a wind chute escape system using a wind pressure to control the descending speed of a person inside a wind chute. A strong landing pressure produced by a landing blower is used to decelerate the descending body to a safe landing speed. The wind pressure inside the wind chute is produced and controlled by a wind blower and the landing blower or by one of them. There are mainly two forces acted on the descending body inside the wind chute, the downward gravity and the upward wind pressure. The balance of theses two forces determines the descending speed of the escapee. Since the wind pressure inside the wind chute is under control, the descending body can be control to a desired speed. Since the wind pressure loss is small in large wind chutes of 1 to 5 feet. in diameter, and the wind pressure transfers inside the wind chute in a speed of sound, this wind chute escape system can be used for high-rise buildings or skyscrapers of hundreds, even thousands of feet high.
