  • Publication number: 20240130156
    Abstract: A light-emitting element includes a pair of electrodes, a first light-emitting unit, a second light-emitting unit, and a charge generation layer. The first light-emitting unit, between the pair of electrodes, and the first light-emitting unit, includes a first light-emitting layer. The second light-emitting unit, between the pair of electrodes, includes a second light-emitting layer. A first luminescent layer includes a first main body material, a second main body material, a first guest material, and a first auxiliary material, and the first main body material forms a first excimer complex with the second main body material. A first excited triplet state energy level of the first auxiliary material is lower than a first excited triplet state energy level of the first excimer complex, and the first excited triplet state energy level of the first auxiliary material is higher than that of the first guest material.

  • Publication number: 20220371634
    Abstract: Embodiments of the present disclosure provide a method for waking up a train which in four carriages coupling mode from sleep state on double-track-line, a system, an electronic apparatus, and a computer-readable storage medium. The method comprises steps of: receiving a static test request transmitted by a train in four carriages coupling mode on the track B1 or the track B2, determining whether a test environment of the train satisfies a static test condition, and transmitting a static test permission instruction to the train; receiving a dynamic test request transmitted by the train, determining whether a test environment of the train satisfies a dynamic test condition, and transmitting a dynamic test permission instruction to the train; and receiving information, indicating that the train can be woken up, transmitted by the train, and controlling the train to wake up from sleep state.

  • Patent number: 10761509
    Abstract: Method and system for automatically generating data points in a data management system. A control strategy and variables used in the control strategy can be configured, wherein the control strategy governs a data management system associated with a controller. The control strategy and the variables can be downloaded to the controller after configuring the control strategy and variables. The control strategy is then run on the controller and published to the data management system before, during, or after downloading of the control strategy. All available variables in the controller are then automatically listed so as to generate data points that can be downloaded and updated through a communication channel between the data management system and the controller.

  • Patent number: 10268611
    Abstract: A method includes automatically assigning, by at least one processor, an IEC address to an I/O binding variable for an RTU. This includes identifying a type of the I/O binding variable and identifying a size of the I/O binding variable based on the identified type. The size represents a number of memory locations to be used to store the I/O binding variable in at least one memory of the RTU. This also includes, in response to determining that the at least one memory contains a free space to store the I/O binding variable based on the identified size, assigning the IEC address identifying the free space to the I/O binding variable.

  • Patent number: 7552771
    Abstract: Provided embodiments relate to introducing a water-drainage-rate-enhancing agent into a subterranean formation to enhance gas production following a relative-permeability-modifier treatment to decrease undesired water production. An exemplary embodiment provides a method of treating a subterranean formation such that initiation of gas production is enhanced following the treatment, the method comprising: introducing a relative-permeability modifier into at least a portion of the subterranean formation such that the relative-permeability modifier reduces permeability of the portion to aqueous fluids; and introducing a water-drainage-rate-enhancing agent into at least a portion of the subterranean formation. Another exemplary embodiment provides a treatment fluid comprising a carrier fluid, a relative-permeability modifier, and a water-drainage-rate-enhancing agent.
