20110155669 | METHOD FOR TRACE PHOSPHATE REMOVAL FROM WATER USING COMPOSITE RESIN - The invention discloses a novel method for trace phosphate removal from water by using a composite resin. Firstly, adjusting the pH value of the raw water to 5.0˜9.0 and prefiltering the water, then leading the filtrate through an absorption tower packed with the composite resin, the trace phosphate in the water is therefore absorbed onto the composite resin; stopping the absorption run when it reaches the leakage point, using a binary NaOH-NaCl solution as the regenerant of the exhausted sorbent, followed by rinsing the composite resin-filled absorption tower with saturated carbon dioxide solution to regenerate the resin. In this invention, a composite resin with nanosized hydrated ferric oxide (HFO) or hydrous manganese dioxide (HMO) particles loaded on its surface is adopted as the absorbent for enhanced phosphate removal from water. A significant decrease of phosphate content in the effluent from this treatment system is found from 0.05-20 ppm to less than 20 ppb (calculated in P), despite of the coexisting competing anions as sulfate, chloride, and hydrocarbonate at much higher molar concentrations than phosphate. This invention is characteristic of large treatment capacity and efficient regeneration for repeated use of the absorbent. | 06-30-2011 |

20110155669 | METHOD FOR TRACE PHOSPHATE REMOVAL FROM WATER USING COMPOSITE RESIN - The invention discloses a novel method for trace phosphate removal from water by using a composite resin. Firstly, adjusting the pH value of the raw water to 5.0˜9.0 and prefiltering the water, then leading the filtrate through an absorption tower packed with the composite resin, the trace phosphate in the water is therefore absorbed onto the composite resin; stopping the absorption run when it reaches the leakage point, using a binary NaOH-NaCl solution as the regenerant of the exhausted sorbent, followed by rinsing the composite resin-filled absorption tower with saturated carbon dioxide solution to regenerate the resin. In this invention, a composite resin with nanosized hydrated ferric oxide (HFO) or hydrous manganese dioxide (HMO) particles loaded on its surface is adopted as the absorbent for enhanced phosphate removal from water. A significant decrease of phosphate content in the effluent from this treatment system is found from 0.05-20 ppm to less than 20 ppb (calculated in P), despite of the coexisting competing anions as sulfate, chloride, and hydrocarbonate at much higher molar concentrations than phosphate. This invention is characteristic of large treatment capacity and efficient regeneration for repeated use of the absorbent. | 06-30-2011 |

20130059615 | Resource Distribution Method for Throughput Maximization in Cooperative Cognitive SIMO Network - The invention relates to a resource distribution method for throughput maximization in a cooperative cognitive SIMO network. The primary user sends data after receiving a cooperation confirmation message, and the cognitive network keeps silence, receives the information data of the primary user and simultaneously decodes the data.

The cognitive base station eliminates the interference of the data of primary user in the received mixed signals and performs beamforming on the signals after eliminating the interference. According to the combined adjustment of the transmission power vector, the power distribution factor vector and the beamforming weight vectors of the cognitive SIMO network, the maximum throughput performance can be realized in the cognitive network while the target transmission rate of the primary user is ensured, furthermore, very fast convergence rate can be realized in the proposed resource distribution method. | 03-07-2013 |

20110101951 | Zero-Voltage-Switching Self-Driven Full-Bridge Voltage Regulator - non-isolated full bridge (FB) converters have self-driven synchronous rectifier (SR) MOSFETs in the current doubler rectifier (CDR). The gate terminals of the SR MOSFETs are connected to the bridge leg midpoints of the FB converter. The primary side of the FB converter shares the same ground of the secondary side, which provides the gate drive path for the SRs. The asymmetrical control featuring zero-voltage-switching (ZVS) capability is applied to the two bridge legs of the FB converter respectively.

High gate drive voltages can be used to reduce the on-resistance of SRs and the conduction loss. In this way, no additional gate driver circuitry is needed for the SRs compared to the conventional external drive circuitry for SRs. In this invention, the above features provide high conversion efficiency with high switching frequency. This can help to achieve high power density and fast dynamic response accordingly.
