Abstract: The present disclosure relates to a method for controlling a contactor, wherein power is supplied to the contactor by a power supply external to the contactor. The method includes: in response to determining that a power supply voltage of the power supply is greater than a first voltage threshold, determining whether an abnormal current drop process occurs; and in response to determining that the abnormal current drop process occurs, controlling a first power supply time, during which a first power supply voltage for the contactor is supplied, to be extended from a preset first value to a second value, wherein the abnormal current drop process indicates that the contactor fails to attract as expected. The present disclosure also relates to a contactor system, a computer program product and a computer-readable storage medium.

Abstract: A bicycle pedal includes a pedal shaft and a pedal body rotating connected with a spindle. The mentioned pedal body is provided with a fixing hook mechanism and a movable hook mechanism for fixing the anti-slip nail. The mentioned fixing hook mechanism includes a first fixing component and a second fixing component which is fixedly attached to the mentioned pedal body. The mentioned second fixing component is rotating connected with the mentioned movable hook mechanism. The mentioned first fixing component and movable hook mechanism clamp together to fix the anti-slip nail. The traditional integrated fixed hook structure is disassembled into two parts, combined with the frame type pedal body, can reduce the gap on the pedal which will attached to the mud, and also makes the pedal structure simpler and clearer, the structure of the parts is relatively independent, makes the mud less likely to attach to the pedal.

Abstract: A handrail safety control device, a transportation system and a handrail safety control method. The handrail safety control device is provided for a transportation system having a handrail, the handrail including a body and a handrail belt, the handrail belt being driven under power to move relative to the body and forming an engaged state or a disengaged state with the body. The handrail safety control device includes: a contact portion disposed in a preset section of the handrail, the contact portion being in a first state or a second state respectively when the handrail belt in the preset section is in the engaged state or the disengaged state, wherein in the first state, the contact portion is in contact with the handrail belt, and in the second state, the contact portion is at least partially out of contact with the handrail belt; and a signal generation portion.

Abstract: A method for arranging a clock-distribution device of an IC is provided. An initial placement of the IC is obtained. The initial placement includes a first portion corresponding to a clock-distribution device, a second portion corresponding to a plurality of modules, and a third portion corresponding to a clock-generation device. The clock-distribution device distributes a plurality of first clock signals to the modules according to a second clock signal from the clock-generation device. The first portion is selected from the initial placement. Clocks within the selected first portion are distributed to obtain a fourth portion of the clock-distribution device. The fourth portion is placed in the initial placement to replace the first portion and to obtain a final placement of the IC. Each module has an input port corresponding to the individual first clock signal, and the clock-generation device has an output port corresponding to the second clock signal.

Abstract: A clock-distribution device for dividing a clock signal into a plurality of clock signals for a plurality of registers is provided. The clock-distribution device includes at least one mesh driver and a clock mesh. The mesh driver is coupled to an input port of the clock-distribution device to transmit and divide the clock signal from the input port. The clock mesh is driven by the mesh driver and is utilized to uniformly distribute the clock signals for the registers.
