The method includes comparing a signal quality monitor (SQM) register value with a predetermined threshold. If the SQM register value is less than or equal to the predetermined threshold, a microcontroller unit (MCU) reads and determines the rx_lol state bit value of a clock and data recovery (CDR) chip. If the rx_lol state bit value reaches a low logic level value at least 3 times, the MCU converts the state bit values of rx_lol and mod_nr into low logic level values, or else, convert the state bit values of rx_lol and mod_nr into high logic level values. If the SQM register value is greater than the predetermined threshold then the state bit values of rx_lol and mod_nr will be left unchanged. When there is no data input to the CDR chip, the method of the present invention will maintain rx_lol and mod_nr at high or low logic level values to stabilize the output state of the optical transceiver. | 05-22-2014 |

To improve the throughput over such a channel, it is proposed to: estimate the quality of each subchannel of a channel, classify the subchannels into a number of quality groups based on the estimated quality, and select a code rate per quality group. This selected code rate per quality group is then used when a data word to be transmitted is coded. Simulations have shown that by grouping the subchannels into a limited number of groups, for example one to four groups depending on the channel quality variation, a high throughput could be achieved with a minimum of signaling cost in the form of extra overhead. | 09-25-2008 |

20100166217 | METHOD OF AND CIRCUIT FOR ADJUSTING FREQUENCY OF A DRIVING SIGNAL OF ELECTRONIC HORN BY MEANS OF CAPACITOR - The present invention discloses a driving circuit for electronic horn and a driving method for the electronic horn. The driving circuit includes an oscillating circuit, which generates a signal having oscillating frequency. Based on the signal, said driving circuit generates a driving signal to drive the electronic horn to produce sound. It is characterized in that said oscillating circuit includes a variable capacitor, and the oscillating frequency is changed by adjusting capacitance of the variable capacitor so as for the frequency of the driving signal to be consistent with working frequency of the electronic horn. The present invention overcomes the problem of mismatch between the frequency of circuit's driving signal and the horn's sounding diaphragm and horn's tone inflexion due to resistance change caused by vehicle vibration. | 07-01-2010 |

20090076205 | Preparation method of small particle sized polybutadiene latex used for the production of ABS - A preparation method of small particle-sized polybutadiene latex used for the production of ABS is disclosed, which includes putting components comprising 34.00-45.00% by weight of the butadiene, 0-6.0% by weight of the second monomer, 52.11-63.13% by weight of the desalinized water, 0.12-0.22% by weight of the mercaptan(TDM), 0.80-2.60% by weight of the emulsifiers composed of potassium abietate and potassium oleate, into the same polymerization reactor, then heating the mixture of the components and stirring the same at a temperature range of 60-75° C. The reaction lasts for 9-12 hours and the conversion is higher than 97%. The method has the advantages such as higher conversion, shorter reaction period and lower latex viscosity. During the first stage of the reaction, more heat is released by increasing the reaction rate. When the conversion reaches 40-80%, the heat release rate of intermediate stage is depressed by decreasing the reaction temperature. When the conversion is higher than 80%, the reaction temperature reaches the highest. Thus, severe heat release is avoided. Moreover, the butadiene polymerization can be controlled steadily and the reaction period is shortened. | 03-19-2009 |
