Abstract: A feedback system for identifying an external force, includes an operation plate and a pressure-sensing unit. The pressure-sensing unit includes an elastic member supporting the operation plate and a pressure sensor inside the elastic member. The pressure sensor includes a pressure sensitive film. An inner side of the elastic member is filled with fluid material which acts on the pressure sensitive film. The operation plate is driven by the external force to be slant which extrudes the elastic member to deform so as to change fluid pressure of the fluid material limited in the elastic member, and such change of the fluid pressure can be sensed by the pressure sensitive film of the pressure sensor so as to identify the movement and the intensity of the external force.

Abstract: A detection device for detecting existence of urine or excrement in a diaper includes a sensor mounted on a diaper, and a receiver mounted on a care-taker. When the sensing line of the sensor detects that the variation of moisture of the diaper exceeds a determined value during a period time, the sensor may emit a wireless signal that may be received by the receiver mounted on the body of the care-taker. At the same time, the wireless signal received by the receiver may be converted into a warning signal in the form of sound or vibration, so as to inform the care-taker to replace the diaper.

Abstract: A waterproof vehicle parking shade device includes a shade having a space for receiving and parking a vehicle, a bottom board mounted on a bottom of the shade, multiple inflatable strips mounted on a peripheral face of the shade and capable of supporting the entire shade after inflation, and a door plate secured on one end of the shade for closing and sealing the shade, to prevent water from entering the shade, thereby preventing the vehicle in the shade from being soaked in the water.
