Abstract: An interphone includes a processor, and a microphone, a camera, a wireless communicating module, a speaker and a display panel electrically connected with the processor. The interphone further includes a brightness detecting device electrically connected with the processor. The brightness detecting device detects a brightness of outer environment. When the interphone is communicating with other interphones, the processor adjusts a brightness of the display panel according to the brightness of outer environment detected by the brightness detecting device. An interphone system and a method for adjusting a brightness of a display panel of an interphone are also provided.

The camera is configured to obtain image information in front of the display unit. The control unit receives the image information of the camera, and adjusts the content of the display unit according to the image information of the camera.

Abstract: A weather monitoring system includes a plurality of weather stations located at different regions. Each weather station includes a processor; a power controller to provide power for the weather station; a sensor to detect weather conditions of the region where the weather station is, and transmit the weather condition to the processor; an emitter to transmit the weather conditions to other weather stations; a receiver to receive the weather conditions from the other weather stations; and a display device to display the weather conditions. A streetlamp system having the weather monitoring system is also provided.

Abstract: A bio-degenerable bone cement is made of a mixture of poly (propylene fumarate) (PPF) and a diphasic material of tetra-calcium phosphate (TTCP)/dicalcium phosphate anhydrous (DCPA). The bone cement produced by a manufacturing method is injectable, bio-degenerable and non-penetrable to radioactive rays and features the advantages of a compressive strength close to the strength of bones, a low polymerization temperature, and a high biological compatibility.
