Abstract: A circuit breaker, comprising a housing, an operation assembly, an arc extinguishing device, and a transmission mechanism. The housing has, in a first direction, a bottom and a top opposite to each other, an accommodation portion recessed from the top to the bottom, and an accommodation cavity semi-surrounding the accommodation portion; a rotating wheel and a movable contact connected to the rotating wheel are provided in the accommodation cavity close to the top and adjacent to the accommodation portion in a second direction, wherein the first direction intersects the second direction; the operation assembly is rotatably and detachably connected to the top of the housing; the arc extinguishing device comprises an arc extinguishing chamber located in the accommodation cavity and close to the bottom of the housing. The circuit breaker can avoid interference between the transmission mechanism and other components while increasing the size of the arc extinguishing chamber.

Abstract: A pile-side lateral static load device includes a jack system, a liftable jack cart, a loading jack fixing system, and a loading system. The jack system includes a jack body. The jack system is installed on the liftable jack cart through the loading jack fixing system. The loading system is installed on the loading jack fixing system, and the loading system includes counter-pressure loading systems and counter-tension loading systems. The pile-side lateral static load device has a simple structure, is convenient to install and operate, and can complete lateral loading and in-situ tests under different pile diameters, different tonnages and different precisions, so as to facilitate a simulation test of in-situ lateral loading of a pile.

Abstract: An intelligent service platform and method comprising a theme type determining module, a matching module, a theme type recognition module, an application recognition module, an application importing module, and a program starting module, wherein the theme type recognition module recognizes, after receiving a first manipulation instruction from a user, a theme type corresponding to the first manipulation instruction, and displays each application matching the theme type on a display screen; and the application recognition module recognizes, after receiving a second manipulation instruction from the user, an application corresponding to the second manipulation instruction, imports the corresponding application through the application importing module, and starts the operating of the application through the program starting module.

Abstract: A clock frequency is controlled by determining a cumulative duty cycle according to a ratio of a cumulative time, during an interval, that the clock frequency has a frequency greater than or equal to a design frequency threshold value to a duration of the interval. A frequency of the clock frequency is controlled to be a first frequency value when the cumulative duty cycle is less than a first duty cycle threshold; and controlled to be a second frequency value substantially less than the first frequency value when the cumulative duty cycle is greater than a second duty cycle threshold. The second duty cycle threshold is greater than or equal to the first duty cycle threshold.
