Abstract: A lighting apparatus includes a first light source, a second light source and a driver. The first light source has multiple first LED modules. The second light source has multiple second LED modules. The driver controls the first light source and the second light source to generate an output light of a required mixed color temperature. The driver selects a first subset of the multiple first LED modules and a second subset of the multiple second LED modules to generate a first output light with a first color temperature. The driver selects a third subset of the multiple first LED modules and a fourth subset of the multiple second LED modules to generate a second output light with a second color temperature. The first subset is not equal to the third subset. The second subset is not equal to the fourth subset.

Abstract: A micro kernel scheduling method and apparatus are disclosed in embodiments of this disclosure. The method is applied to a software platform and includes: receiving a scheduling instruction for a current micro kernel; and switching the current micro kernel to a target micro kernel. In some embodiments, a micro kernel is switched directly according to a scheduling instruction, and this is completed without any thread of the software platform, which solves the problems in the conventional system of high micro kernel switching cost and poor real-time performance caused by one-to-one correspondence between micro kernels and threads of the software platform.

Abstract: A vertical ring high gradient magnetic separator comprises an exciting winding coil and a coil casing, wherein the winding coil is immerged in coolant in the coil casing, the winding coil is of a multi-layer structure, and an insulating member is provided between each layer or a plurality of layers of the winding coil to form gaps through which the coolant passes. The winding coil of the vertical ring high gradient magnetic separator has a rapid heat dissipation capability in the coolant, which can ensure the winding coil maintaining a lower temperature during operation, thereby obtaining a higher magnetic field strength.
