Abstract: A method for automatically turning an agricultural machinery to follow a set route in a defined work area when carrying out a farming procedure in a field controls the machine to decelerate and change direction when a turn round command is received. The work area includes at least two work channels, the agricultural machinery reaching the straight-line end of one work channel is turned to enter the next work channels. The agricultural machine is slowed down to a speed set for safe turning, any working equipment is retracted, and the agricultural machinery is turned round into new work channel. The working equipment is released again, and the agricultural machine continues its farming procedure along the new work channel. A system for such automatic turning and applications are also disclosed.

Abstract: Automated multi-round task-based conversation with a user is disclosed. In a first round conversation between a user and a data processing system involving first task(s), the data processing system cognitively identifies first entity(ies) and one or more first intent(s), based on a first input statement received by the data processing system from the user. In a subsequent second round conversation between the user and the data processing system involving second task(s) different from the first task(s), the data processing system cognitively identifies second entity(ies) and second intent(s), based on a second input statement received by the data processing system from the user. The data processing system reuses at least one of the first entity(ies) in the second round conversation.

Abstract: The present invention relates to the technical field of head-up display, and particularly relates to a head-up display system for an automobile. The head-up display system comprises a projection light source and laminated glass, and further comprises a transparent nanofilm; said film comprises at least two dielectric layers and at least one metallic layer; the projection light source is used for generating p-polarized light; the p-polarized light is incident on a surface of an internal glass panel distal to an intermediate film, said light having an angle of incidence of 42 to 72 degrees, such that the transparent nanofilm can reflect part of the incident p-polarized light.

Abstract: An air conditioning system and a method for controlling the same are provided. The air conditioning system includes an enhanced vapor injection compressor, first and second direction switching assemblies, first and second heat exchangers and a flash evaporator. The enhanced vapor injection compressor has an air discharge port, an air supplement port, first and second air suction ports, and an air return port. Pressure in a sliding vane chamber of an air cylinder corresponding to the second air suction port is equal to a discharge pressure at the air discharge port. A first pipe port of the first direction switching assembly is connected with the second air suction port, a second pipe port thereof is connected with the air discharge port and a third pipe port thereof is connected with the liquid accumulator, and the first pipe port is communicated with one of the second and third pipe ports.
