  • Publication number: 20140148078
    Abstract: A method and system for wireless communication are disclosed. The method comprises: the master device generates a sequence code through a specific encoder and transmits the sequence code to each slave device continuously within a preset period according to the communication demand, wherein the specific encoder is a feedback shift register constructed by a specific polynomial, of which the coefficients and the order are in correlation with the communication demand while all of the coefficients and initial values are not equal to 0 at the same time; the preset period is greater than or equal to the sum of a sleeping period and a detecting period of the slave device, which constitutes a sleeping-and-waking cycle; the slave device receives a continuous section of the sequence code in the detecting period, decodes the sequence code through a decoder corresponding to the encoder, and performs corresponding operation according to the decoding result.

  • Patent number: 8735176
    Abstract: The present invention relates to a metal oxide nano-composite magnetic material, fabrication method, and method for linkage, enrichment, and isolation of phosphorylated species. The metal oxide nano-composite magnetic material comprises the magnetic iron oxide nanoparticle, a silica layer immobilized onto the magnetic iron oxide nanoparticle and a metal oxide layer coated onto the silica layer. The magnetic iron oxide nanoparticles can be used for absorbing microwave radiation to accelerate the enrichment and linkage for phosphorylated species onto the metal oxide nano-composite magnetic material. Furthermore, the magnetic property of magnetic iron oxide nanoparticles leads to isolation of the metal oxide nano-composite magnetic material-target species conjugates by simply employing an external magnetic field.

  • Patent number: 8690630
    Abstract: A bubble generating toy includes a bubble forming assembly mounted inside a housing behind a front opening thereof. The bubble forming assembly includes a cylindrical body having diametric inlet and outlet, a cylindrical air gate having diametric inlet and outlet. The air gate is rotatable in the cylindrical body between a closed position and open position when the inlets and outlets are aligned. A sleeve extends perpendicularly from the outlet of the cylindrical body and has a bubble ring. Bubble forming liquid is pumped from a container, through a tube and into the sleeve by a pump to form a bubble film across the bubble ring. An air blower blows are through the sleeve and the bubble ring to generate bubbles.

  • Patent number: 8573876
    Abstract: A ring binder mechanism for retaining loose-leaf pages securely holds closed ring members together to prevent inadvertent loss of pages retained by the mechanism. The mechanism comprises a housing supporting two hinge plates for pivoting motion to open and close paired ring members mounted on the plates. Free ends of the paired ring members have interlocking configurations that securely join together when the ring members close. The configurations prevent misalignment of the closed ring members in all directions transverse to longitudinal centerlines of the ring members. The mechanism also includes locking elements that interact with the hinge plates to block their pivoting motion when the ring members are closed. This holds the free ends of the closed paired ring members together so that the interlocking configurations of the ring members remain interengaged.

  • Patent number: 8147160
    Abstract: A ring binder mechanism includes a housing and a ring support supported by the housing for movement relative thereto. Each ring of a plurality of rings includes first and second ring members. The first ring member is mounted on the ring support for movement with the ring support relative to the housing between a closed position and an opened position.

  • Publication number: 20120055175
    Abstract: A hybrid air conditioning system for a combustion engine vehicle. When the combustion engine is running and a rechargeable battery unit is not at full charge, an electric machine is configured by an MCU control unit as mechanically coupled to the combustion engine, and a battery charger is configured as electrically connected to the rechargeable battery unit such that the electric machine generates electric power to recharge the rechargeable battery unit. When the combustion engine stops and air conditioning is required, the rechargeable battery unit is configured by the MCU control unit as electrically connected to a motor drive, and the electric machine is configured as mechanically coupled to the compressor to provide mechanical power to drive the compressor. This allows the automobile air conditioning system to operate for a limited period of time after the combustion engine stops.
