Abstract: A method, computer program product and system are provided for preloading debug information based on the presence of incremental source code files. Based on parsed input parameters to a source code debugger, a source code repository and a local storage area are searched for an incremental file. In response to the incremental file being located, a preload indicator in the incremental file, which is a source code file, is set. Based on the preload indicator being set, debug symbol data from the incremental file is merged to a preload symbol list. In response to receiving a command to examine the debug symbol data from the incremental file, the preload symbol list is searched for the requested debug symbol data.

Abstract: A medical pump includes a single phase synchronous motor, a rod piston, a cylinder for receiving the rod piston for reciprocating motion therein. The single phase synchronous motor includes a stator and a rotor rotatable relative to the stator. The rotor includes a plurality of permanent magnets. The stator comprises a stator core and a winding wound around the stator core. The stator core comprises two opposed pole portions that define there between a rotor receiving space for receiving the permanent magnets. The medical pump has a compact structure. In addition, the motor of the medical pump has a constant rotation speed and has a smaller size and less weight under the same output power conditions as traditional motors used in medical pumps. The medical pump is particularly suitable for use in atomizers.

Abstract: A cooling fan and an air-cooled refrigerator are provided. The cooling fan includes a synchronous motor and an impeller. The synchronous motor includes a stator and a permanent magnetic rotor. The permanent magnetic rotor includes a rotary shaft and a permanent magnetic rotor main body attached around the rotary shaft. The stator includes a stator core and a stator winding wound around the stator core and powered by an alternating-current power supply. The permanent magnetic rotor operates at a constant rotational speed of 60f/p during a steady state operation of the motor, where f is a frequency of the AC power source and p is the number of pole pairs of the permanent magnet poles. The impeller is connected to the rotary shaft for rotation under the driving of the rotary shaft.
