A solar power system may comprise a solar panel set, a controller, a lithium battery set, and at least a DC load. The controller has a control unit built therein to control a double-contact relay, a single-contact relay, and a transformer. The rated voltage of the solar panel set is higher than the rated voltage of the lithium battery set between 115% and 130%. When the actual voltage of the solar panel set is lower than 115% of the rated voltage of the lithium battery set, the solar panel set is configured to low-loss charge the lithium battery set under the low illumination condition. When the actual voltage of the solar panel set is higher than 115% of the rated voltage of the lithium battery set, the solar panel set under the high illumination condition is adapted to have voltage-drop through the transformer and high-efficiently charge the lithium battery set.

A pen structure with a glass smasher has the glass smasher mounted at the front end of a pen. When a user holds the pen and presses the front end (i.e., the smashing cone) of the smashing rod of the glass smasher forcibly against a glass obstacle, an impact block will strike the rear section of the smashing rod vigorously such that the smashing cone is instantly driven to smash the glass obstacle. A ballpoint/rollerball refill is detachably provided in the pen and is at least 6 cm long in order to contain enough ink. The overall length of the pen is at least 10 cm so that the pen can be easily held while the user writes or draws with the ballpoint/rollerball tip and while the user applies a force to a glass obstacle through the front end of the smashing rod to smash the glass obstacle.

The present invention is directed to a system and method of adaptively controlling a light-emitting diode (LED) backlight. A content analyzer analyzes luminance of image data to be displayed on a display panel. An LED current controller controls illumination of the LED backlight via an LED driver according to an analysis result of the content analyzer. The LED current controller over-drives the LED backlight such that a drive current flowing in the LED backlight is above a normal current, when the analysis result of the content analyzer indicates that the luminance of image data is above a predetermined value.

A server rack heat dissipation system for a server including an electronic component comprises a first and a second heat dissipation assembly. The first heat dissipation assembly includes a first heat exchanger and a first pipeline. The first heat exchanger is inside the server rack and in thermal contact with the electronic component. The first pipeline is in thermal contact with the first heat exchanger and has a first coolant. The second heat dissipation assembly includes a second heat exchanger. The second heat exchanger is inside the server rack and in thermal contact with the first pipeline. The second heat exchanger can remove the heat of the electronic component in the first coolant in advance. Accordingly, the time of the first coolant being maintained in a vapor phase can be shortened, so that a power the fluid driving device used for driving the first coolant is reduced.
