Abstract: An electricity-producing shoe comprises a shoe body including an electricity-producing module and an electricity generator mounted therein. The electricity-producing module includes a rack, first and second gears, and a spring buffer that mounts between the first and second gears. The first and second gears are engaged with the rack and an axial gear of the electricity generator, respectively. The electricity generator has an electricity output terminal connected to an electric device of the shoe body. As a result, the rack drives the first gear and the second gear drives the axial gear of the electricity generator by means of normal stepping motion of walking for producing electric power and thereby supplying the electric power for the electric device.

Abstract: A shock-absorbable electricity-producing apparatus comprises an electricity generator and an electricity-producing module. The electricity-producing module includes a rack, first and second gears, and a spring buffer. The rack is synchronously driven by a shock absorber. The spring buffer is located between the first and second gears. The first and second gears are engaged with the rack and an axial gear of the electricity generator, respectively. An electricity output terminal of the electricity generator is connected to an electric device. As a result, the rack drives the first gear by means of gravity drop that forms during movement of the shock absorber to enable the electricity generator to produce electricity. Consequently, the shock-absorbable electricity-producing apparatus absorbs shocks and produces the electricity insensibly without causing burden and resistance.

Abstract: In an anti-decoupling structure for a USB connector, a hooking device is mounted on a terminal base. A control plate is extended from the hooking device. A hidden lock is mounted behind the control plate. The terminal base, the hidden lock and the hooking device are packaged by the outer shell to form a unity, whereby the USB connectors are protected from being decoupled by using the hooking device. Besides, the hooking device is locked or unlocked by controlling the hidden lock to protect the USB connectors from being stolen.

Abstract: An apparatus for leaving a message on a refrigerator is disclosed. The apparatus can be mounted on the refrigerator so as to broadcast a voice upon opening a door of the refrigerator. A control unit for processing and controlling the voice is mounted on the main body of the present invention, wherein the control unit is a signal processing control center. A sensor is mounted on the inner side of the door of the refrigerator and is connected to the control unit of the main body. When the door of the refrigerator is open, the sensor is triggered to transmit a sensor signal to the control unit to broadcast the voice. A timer is also connected to the control unit to active the apparatus at a predetermined time. In other words, a predetermined voice content is broadcasted. Thus, the reminding, warning, and encouraging effects are accomplished so as to act an interactive communication medium for family members.
