Abstract: An electric louver awning comprises an awning frame, a driving mechanism, and a plurality of louver assemblies. The awning frame comprises two parallel cross beams, the plurality of louver assemblies are connected between the two cross beams and the left and right ends of each of the louver assemblies are hinged with the two cross beams respectively; the left and right ends of each of the louver assemblies are hinged with connecting rods respectively, and the hinge points of the louver assemblies and the connecting rods are arranged eccentrically to the hinge points of the louver assemblies with the cross beams; the driving mechanism is used to drive the connecting rods to move forward and backward.

Abstract: Systems, methods, and apparatus, including computer-readable media, for managing and deploying customized artificial intelligence chatbots. In some implementations, a system receives data indicating user input instructing a chatbot to be created and an indication of a data set for the chatbot to use. The system creates the chatbot based on data objects in the data set. The system provides a code segment or module configured to cause a chatbot interface for interacting with the chatbot to be embedded in a user interface. The system receives a user prompt provided for the chatbot through the user interface. The system provides a response to the user prompt from the chatbot, and the response from the chatbot includes text generated by one or more artificial intelligence and/or machine learning (AI/ML) models using values from the data set.

Abstract: The present application discloses a DC converter and a control method of a PWM controller, including a PWM controller. The PWM controller alternately outputs two state signals, a first state signal is configured to control a first switch SW1 and a second switch SW2 to turn on; a second state signal is configured to control a third switch SW3 and a fourth switch SW4 to turn on. The PWM controller is configured to output a fourth state signal for controlling the first switch SW1 and the third switch SW3 to turn off when it is determined that the first terminal voltage VOP of the positive voltage output capacitor COP is greater than the first target voltage VM1, the PWM controller.

Abstract: The present application discloses a control circuit and method of a single-mode dual-current-path step-down/step-up converter, including: during a charging period of an inductor, controlling a first switch, a fourth switch and a fifth switch to close, and controlling a second switch, a third switch and a sixth switch to open, so as to discharge a first capacitor and a second capacitor, and increase a current of the inductor; during a discharging period of the inductor, controlling the first, the fourth and the fifth switches to open, and controlling the second, the third switch and the sixth switches to close, so as to charge the first and second capacitor, and reduce the current of the inductor.
