Abstract: A disc data destroy system, including a light, the light is used to illuminate a DVD/VCD disc, the disc is a DVD+/-R or VCD+/-R, the disc is already recorded and therefore its has two area: a illuminated/recorded dye area and a non-illuminated/non-recorded dye area, wherein, the disc destroy system illuminates the non-illuminated/non-recorded dye area to destroy the data of the disc. MD: A method and device to destroy the data on the DVD+/-R or CD-R by the laser. People used to use a paper shredder to cutting waste paper and waste CD/DVD disk, now I provide a new method and/or machine to use laser to cleanly destroy/erase the data on the DVD+/-R or VCD+/-R. We can also use a general DVD recorder that we can see in nowadays market to complete this goal. A fitness equipment have a main surface to bear a body to do exercise, the main surface and a plane-line forms a main angle, the main surface has a close-head-end and a close-foot-end, the fit equipment can adjust the strength that needed to the exercise by adjusting the main angle. MD: A computer having a inside memory, including a case to contain a external memory. A camera that includes a sound device, when shooting, the camera trigs the sound device. MD: When we use MP3 player to hear the FM radio, we may hear a beautiful music and then quickly press the record switch to record it. But the problem is that the MP3 player always take a few seconds to run up the record software and therefore the recorded music is always not a complete one. The invented MP3 Player will always keep on recording the FM radio, and therefore when the user formally press the record switch, he can record a complete music. This invented MP3 player also has a alarm function, the new MP3 player use the music stored inside as the alarm ring. The new invented self defense protection spray also have siren function, it can spray and make siren at the same time. Thus, the new protection spray give people double protections. The spray nozzle is designed to as a whistle so that it can spray and sound at the same time. MD: A new invented thermometer which can be used to keep in watching the temperature of a sick and sleeping baby for a long period of time. When the temperature reaches the high limit, the thermometer will automatically alarm and make a siren to weaken the parents. It also can be applied on the patient and elders. The thermometer can be designed as a sticker. The thermometer can also be designed as a sleeping pad or a pillowcase so that we can easy to applied it on the sick-sleeping baby. MD: Nowadays the urinal has the sensor for sensing the body, and will flush with the pre-urine flash and the post-urine flash. But if the second person uses the same urinal just a few second after the first person, the urinal still will do the pre-urine flush twice. That wastes the water. This new patent will do the pre-urine flush once only to save the water in this case. A sugar coating wrapper used to wrap up a bitter pill by the hand of parents for the kid who deny to swallow the bitter pill. A car is with the windshield washer reservoir refilled inlet inside the cabin rather than inside the engine bay or under the hood, and thus makes the car convenient to be refilled.
