Abstract: A user equipment assistance information (UAI) negotiation method, for a user equipment (UE) of mobile communication includes receiving a first OtherConfig element of an RRC reconfiguration message comprising a plurality of configuration parameters with SETUP values from a network terminal; sending a first UAI including a first value of a first configuration parameter of the configuration parameters to the network terminal; and receiving a first RRC reconfiguration message corresponding to the first UAI from the network terminal.

Abstract: A fan management system includes a fan and a server. The fan includes a driving circuit, and the driving circuit is configured for driving the fan. The fan operates in an operation mode. The server is connected to the fan and is configured for controlling the operation of the fan. The driving circuit outputs a digital label signal when the fan operates abnormally, and the server obtains a production history, an operation information and a warning message of the fan through the digital label signal. The server adjusts the operation mode of the fan according to the warning message simultaneously.

Abstract: An axial fan includes a fan frame, an impeller and a motor. The fan frame has a frame body, a base and plural connecting members. The base is disposed at the center of a side of the frame body. The connecting members connect the frame body to the base. The impeller is accommodated in the frame body and disposed on the base. The impeller has a rotating shaft, a hub and plural blades disposed around the hub. The motor is disposed on the base and connects with the rotating shaft to drive the impeller to rotate. When the impeller rotates forwardly, the airflow is induced to flow through the connecting members, blades, and one side of the frame body away from the base. When the impeller rotates reversely, the airflow is induced to flow through the side of the frame body, blades and connecting members.

Abstract: The invention provides a monitor circuit, which is used for a fan and receives a driving current and a driving voltage of the fan. The monitor circuit includes sensing circuits and a microcontroller. The sensing circuits respectively sense statuses of the fan and output sensing values. The microcontroller is used for monitoring whether the sensing values exceed preset value ranges respectively to obtain comparison results. The microcontroller outputs warning signals according to the comparison results. Each of the warning signals has a specific frequency.

Abstract: An anti-air-return fan system includes a motor, a driving control circuit, and a rotation judgment circuit. The driving control circuit is electrically connected to the motor. The driving control circuit has a driving signal for driving the motor to rotate according to the driving signal. The rotation judgment circuit outputs a judgment signal to the driving control circuit when detecting that the motor reversely rotate. The driving control circuit executes a braking according to the judgment signal. The driving control circuit drives the motor to operate when the rotation judgment circuit detects that the motor doesn't rotate reversely.

Abstract: A kind of golf umbrella combined with a spare golf ball is mainly set with an assembling mechanism in the end of the handle of a golf umbrella. One lower end of the said assembling mechanism can be simply and firmly set on the handle with ease and it is set with a hemisphere sleeve-fit body to provide a temporary holding of a golf ball. Therefore, it becomes a last spare ball while playing golf and the practical value is thus obtained.
