The controller is configured to control the deck to rotate to the longitudinal direction when the controller controls the handrail assembly to rotate relative to the stand columns to be in the folded state, and control the handrail assembly to rotate relative to the stand columns to be in the unfolded state when the controller controls the deck to rotate from the longitudinal direction to the horizontal direction.

Abstract: The present disclosure belongs to the technical field of analog or digital-analog hybrid integrated circuits, and relates to a high-speed SAR_ADC digital logic circuit, in particular to a high-speed digital logic circuit for SAR_ADC and a sampling adjustment method. The digital logic circuit includes a comparator, a logic control unit parallel to the comparator, and a capacitor array DAC. The comparator and the logic control unit are simultaneously triggered by a clock signal. The comparator outputs a valid comparison result Dp/Dn, the logic control unit outputs a corresponding rising edge signal, the rising edge signal is slightly later than Dp/Dn output by the comparator through setting a delay match, Dp/Dn is captured by the corresponding rising edge signal, thereby settling a capacitor array. The present disclosure eliminates the disadvantage of the improper settling of the capacitor array of the traditional parallel digital logic.

Abstract: Methods and systems are presented for providing automated online chat assistance in multiple languages. A query in a first language is received via a chat robot from a user device. The query is machine-translated into a second language and transmitted to an artificial intelligence system that includes a dialog tree configured in the second language. The artificial intelligence system determines a response in the second language to the query by locating a node corresponding to an intent based on the query in the dialog tree. The node includes a node ID and response text in the second language. The artificial intelligence system transmits the second-language response including the node ID to the chat robot. The second-language response is intercepted, and first-language response text corresponding to the second-language response text is determined based on the node ID. The second-language response text is then provided to the user device by the chat robot.
