Abstract: A pre-interception device includes an input portion for a fluid to flow in, an output portion for the fluid to flow out, a plurality of diversion flow channels and a plurality of interception portions. Each diversion flow channel is in communication with the output portion and the input portion, is configured to provide turning guidance for flow of the fluid, and has a fluid lift section. The interception portions are configured to form a turbulent flow field in the fluid. The turbulent flow field can have foreign objects flowing through the diversion flow channel be captured. Accordingly, a filtering effect is achieved based on physical properties of the foreign objects. When the pre-interception device is additionally combined with a filter net to form a filtering system, the burden on the filter net is further alleviated, hence extending a service life of the filter net and reducing costs.

Abstract: A full-open and full-angle stall device for a motor test system is disclosed. The stall device is used to provide a stall function to a motor under test and includes a base, a driving source connection module and a brake module. The driving source connection module includes a coupling and a first disc and a second disc that are detachably joined together. The first disc and the second disc are fixed on the coupling. The coupling is defined with a mounting hole for connecting a transmission shaft so as to receive a driving source from the motor under test. The brake module is disposed on the base and is configured at an edge of the driving source connection module, and is controlled to generate a clamping force on the driving source connection module, wherein the clamping force is selectively applied to any edge of the first disc and the second disc so as to brake the driving source connection module.

Abstract: A liquid cooling system, a liquid cooling method, and an electronic device-testing apparatus having the system are disclosed. When an electronic device is accommodated in a chip slot of a test socket, a cooling liquid supply device supplies a cooling liquid to the chip slot through a fluid inlet portion, and the cooling liquid at least flows over parts of the upper and lower surfaces of the electronic device and then flows out from a fluid outlet portion. The chip slot of the test socket serves as the flow space for the cooling liquid so that the cooling liquid can flow over the upper and lower surfaces of the electronic device, and the electronic device can be immersed in the continuously flowing cooling liquid. The flowing cooling liquid can also take away foreign matter, avoiding the influence of the foreign matter on the test.

Abstract: The present application discloses a motor controller, a motor control method and a computer program product for vehicle assist control. An assist torque command for a motor device to perform vehicle assist control is generated according to an execution command of a vehicle assist determination unit and a rotor position signal and a rotor speed signal of a motor device. An original position signal of the motor device and the rotor position signal are calculated, and a position ratio calculation is performed to generate a front-order torque command. A torque damping command is generated according to the speed ratio calculation based on the rotor speed signal, and is calculated with the front-order torque command to generate an assist torque command. Thus, position information of the rotor of the motor device can be directly used in the calculation and speed information is at the same time used for an assist calculation, thereby preventing an error and solving the issue of sliding during parking.
