Abstract: A solar anti-shadowing circuit coupled to multiple solar cell units connected in series. The circuit includes a metal oxide semiconductor (MOS) switching group. The switching group includes multiple MOS switches, and each of switches is connected to the corresponding solar cell unit in parallel. The circuit also includes a driving unit group, and the driving unit group includes multiple driving units. Each of the multiple driving units respectively outputs a control signal to the corresponding switch. When a shadowing event happen, the driving unit outputs the control signal to the corresponding MOS switch so as to electrically connect the MOS switch.

Abstract: An IC card reading connector having a body is disclosed. The body has an IC card slot. The IC card slot has a movable flat block. A distal end of the movable flat block has an IC card holding plate. A rear side of the IC card holding plate is resisted against by a spring. A lower side of the IC card holding plate is installed with a positioning roller. When the IC card is inserted, the positioning roller is embedded into a receiving hole, then a reaction force is applied to the movable flat block, and then a reaction force is further applied to the positioning roller. By the confining of the receiving hole, the positioning roller and the IC card holding plate serve to hole the IC card. A bottom of the positioning roller has a receiving hole at a rear side of the body; a surface of the movable flat block being installed with a plurality of trenches; each trench being installed with a terminal; and a portion at the trench being in contact with a front end of the terminal having an inclined guide surface.
