Abstract: Disclosed in the present invention is a heat-dissipating head-up display (HUD), including an outer housing, on which a light outlet through-hole is provided; a light source housing, wherein the light source housing and the outer housing are detachably connected, and an optical machine mechanism is also installed in the light source housing, and the optical machine mechanism is used to output image light to the outer housing; the light source housing is also provided with a heat-dissipating through-hole, the optical machine mechanism is also installed with a first heat-dissipating member, and the first heat-dissipating member passes through the light source housing via the heat-dissipating through-hole and extends outwards.

Abstract: Disclosed in the present invention is an efficient heat-dissipating head-up display (HUD), including an outer housing, on which a light outlet through-hole is provided; a light source housing, wherein the light source housing and the outer housing are detachably connected, and an optical machine mechanism is also installed in the light source housing, and the optical machine mechanism is used to output image light to the outer housing; and a heat conducting member is also connected between the optical machine mechanism and the light source housing, and the heat conducting member is used to conduct heat generated by the optical machine mechanism to the light source housing. In the present invention, the heat generated by the optical machine mechanism in the operating process can be directly conducted to the light source housing through the heat conducting member, thus improving the heat conduction efficiency.

Abstract: A method and a system for register clearing in data flow analysis in decompilation are provided. The method includes: reading all function statements in a code file; sequentially judging each of the read function statements, and creating a binary tree and inputting the function statement into the binary tree in a case that the function statement includes a register name; sequentially judging each of the function statements including the register name, and performing an elimination process on the created binary tree to remove the register name from the binary tree in a case that the function statement includes a right child end tag of the binary tree, to generate a simplest binary tree; and generating a function statement in high-level language based on the simplest binary tree. All function statements can be read at a time and multiple reading and writing are avoided in the invention.
