A flow stabilized chip includes a chip mainbody, a buffering chamber and two fluid delivery ports. The chip mainbody has a pipe-connection surface. The buffering chamber is disposed in the chip mainbody. The two fluid delivery ports are disposed on the pipe connection surface and connected to the buffering chamber. The chip mainbody includes, in order from the pipe-connection surface to a bottom of the chip mainbody, a first base plate, a first elastic membrane, a second base plate, a second elastic membrane and a third base plate. The first base plate includes a first opening. The second base plate includes a second opening. The third base plate includes a third opening. The first elastic membrane, the second base plate and the second elastic membrane are stacked in sequence to form the buffering chamber.

A light-emitting diode (LED) streetlight structure, which includes a light-emitting module, a power module, and a lamppost. The light-emitting module is disposed on side of the power module; the lamppost is disposed on the other side of the power module and corresponds to the light-emitting module. A heat-dissipating structure is disposed on the surface of a housing of the power module. The heat-dissipating structure corresponds to a power supply in the power module, and can dissipate the heat generated by the power supply and reduce the temperature thereof. Accordingly, heat dissipation of the power supply is enhanced, and hence increasing its lifetime.

An omni-wheel based driving mechanism includes a spherical wheel, a pair of first omni wheels, and a pair of second omni wheels. The first omni wheels are arranged at two sides of the spherical wheel to space from each other by a predetermined distance in a first direction, so that the spherical wheel is rollably positioned between the first omni wheels. The second omni wheels are arranged at another two sides of the spherical wheel to space from each other by a predetermined distance in a second direction, so that the spherical wheel is rollably positioned between the second omni wheels. Therefore, a good driving efficiency can be obtained between the spherical wheel and the first omni wheels and the second omni wheels.

Disclosed is a sealing detection mechanism for detecting sealing of a closure fastened to a container having a top open end. The sealing detection mechanism includes a RFID tag mounted at a selected position of the closure, at least one operable tear portion formed at the closure, and at least one conductive unit electrically connected to the RFID tag and extended from the RFID tag to the closure to form a conductive circuit loop across the operable tear portion of the closure. A sealing guarantee device mounted is selectively mounted between the top open end of the container and the closure, which includes an upper portion, a lower portion, and a middle portion connected between the upper portion and the lower portion. The lower portion of the sealing guarantee device is provided with an annular flange protruding downward from the lower portion and a hollow portion between the lower portion and the flange.

A learning device using RFID tags is provided. The learning device includes a platform and at least one RFID tag unit. The tag unit includes at least one RFID tag with an identification code and a magnet at the inner space of the RFID tag unit. When the RFID tag unit is placed at an interrogation zone of the platform, the magnet actuates the magnet-induced switch to turn on and drives the power supply device to provide power. The signal Sfrom the RFID tag is transmitted though the RFID reader for decoding and the processing unit for processing. The signal is sent to an audio/video output device for displaying and broadcasting. A plurality of platforms are formed a platform array, each of the platform including at least one receiver and at least one transmitter correspondent to the receiver, the transmitter transmitting a signal which represents the position of the transmitter, while the receiver receiving signals from the transmitter to recognize the relative positions of the platforms.

A switch detection device using RFID tags is disclosed. The switch detection device includes a RFID tag, a conducting circuit loop and a switch connected to the conducting circuit loop to form a control circuit. The switch is controlled to turn on or off, leading to the closing or opening of the control circuit. The RFID tag detects the state of the conducting circuit loop and transmits a signal representing the opened/closed state to a RFID reader. The switch detection device is incorporated to a turning operation mechanism which includes a lever lock assembly, a deadbolt lock assembly, a window sash lock assembly, an odometer wheel, a hinge provided with a first hinge member and a second hinge member interconnected by a central axle, a door closer, a water faucet, a rotatable switch, or a rotatable lock.

Disclosed is a substrate damage detection mechanism using Radio Frequency Identification (RFID) tag including a substrate, at least one RFID tag with a RFID chip, a RFID transmitter and at least one data input/output port and at least one conducting circuit loop arranged to cover the substrate and provided with a first end that is electrically connected to a reference voltage and a second end that is electrically connected to the data input/output port of the RFID tag. The RFID chip generates a conductive code when the conducting circuit loop is originally conducting and generates a open-circuit code when the conducting circuit loop becomes open circuit resulting from the damage of the substrate in which both the conductive code and the open-circuit code are transmitted by the RFID transmitter and received by a RFID reader to determine the damage of the substrate.
