Abstract: A dust removal method using baghouse filter to process raw syngas from fluidized bed coal gasifier, wherein temperature in the baghouse (300) is maintained at 180° C.-250° C., pressure difference between the gas inlet (130) of the baghouse (300) and the gas outlet (110) of the baghouse (300) is controlled at 1000-5000 Pa, the raw syngas from the fluidized bed coal gasifier enters the gas inlet under the pressure of 0.2-3.0 Mpa. The present method effectively solves the technical problems of condensation and baghouse block due to high steam and ash content in the raw syngas from the fluidized bed coal gasifier and the present method is also applicable to remove dusts from the raw syngas produced by the fluidized bed coal gasifier under the conditions of high water-gas ratio (the water-gas ratio is up to 37%), high dust content (15-100 g/Nm3 dusts) and 0.2-3.0 Mpa pressure. The present invention also discloses a baghouse dust collector and a dense phase pneumatic conveying apparatus for the method.

Abstract: An apparatus and method for measuring errors and event occurrences in a multi-valued data stream by using a dual decision bit error rate tester is disclosed. The Bit error rate tester (BERT) includes a plurality of decision circuits operative to provide a respective bit decision output signal in response to an input signal. The bit decision output signal magnitude information of a signal under test as measured over a sample window period. A comparator circuit is coupled to each of the plurality of decision circuits, and is operative to provide an event occurrence signal in response to the bit decision output signals from each of the plurality of decision circuits. The BERT provides the ability to supply additional information and feedback about the behavior and performance of the targeted device or subsystem being tested and to perform error measurements in non-constrained data (i.e. live data).

Abstract: A testing circuit includes a signal generator operative to provide a control signal in response to a reference clock signal. The control signal may include both alignment and timing information operative to synchronize the timing and output of the signal generator with a device under test. A clock recovery instrument is electrically coupled to the signal generator. The clock recovery instrument generates the reference clock signal in response to a clock signal from the device under test. The reference clock signal is synchronized with the clock signal from the device under test such that signal generator operation is synchronized with the device under test independent of the behavior of the device under test.

Abstract: Disclosed herein is a method and apparatus used to detect phase error information between edges of an input data signal and a clock signal for use at ultra-high frequencies and where linear phase error information is required. This invention extends the usefulness of a given integrated circuit logic technology to twice the frequency range of application while maintaining the desired linear phase error measurement operation. Flip flops are used to sample the data input signal with the clocking signal and processing is done separately for rising and falling data edges. Analog recombination of phase error information from both edges is then done in a fashion that is not limited by the integrated circuit speed.
Abstract: Disclosed herein is a method and apparatus used to the measure duty cycle of a clocking waveform utilizing minimal hardware and achieving high accuracy. This invention utilizes digital sampling of the signal to be measured at a rate that can be significantly lower then the clocking frequency of the signal to be measured. It accomplishes broad-band, multi-frequency use by using a time-varying frequency for the sampling clock to make sure that the sampling clock is asynchronous with the frequency of the clocking signal to be measured. The average ratio of the sampled ones (or zeros) as compared to the total number of samples is then computed to derive the measurement of duty cycle.
