20100000305 | METHOD AND KIT FOR ADSORBENT PERFORMANCE EVALUATION - The present invention generally relates to methods and kits for measuring and analyzing degradation of adsorbent materials, particularly for adsorbent materials used in gas separation processes. The present invention can assess the damage to adsorbent due to moisture contamination and it can assess damage that is not moisture-related. The advantage to the present invention is that it can detect degradation of adsorbent before the degradation affects production. Another advantage is that it can conclusively determine whether the sieve is damaged. Because it is so inexpensive to run, the test of the present invention can be conducted to determine adsorbent damage and to confirm whether the damage continues to be an issue. The present invention can test adsorbents in any form, including, but not limited to, bead, pellet or powder form. | 01-07-2010 |
20100000306 | METHOD AND KIT FOR ADSORBENT PERFORMANCE EVALUATION - The present invention generally relates to methods and kits for measuring and analyzing degradation of adsorbent materials, particularly for adsorbent materials used in gas separation processes. The present invention can assess the damage to adsorbent due to contamination including moisture contamination and it can assess damage that is not contaminant-related. The advantage to the present invention is that it can detect degradation of adsorbent directly at the plant site before the degradation affects production. Another advantage is that it can conclusively determine whether the adsorbent is damaged. Because it is so inexpensive to run, the test of the present invention can be conducted to determine adsorbent damage and to confirm whether the damage continues to be an issue. The present invention can test adsorbents in any form, including, but not limited to, bead, pellet or powder form. | 01-07-2010 |

20140126621 | COMMUNICATIONS RECEIVER WITH CHANNEL IDENTIFICATION USING A-PRIORI GENERATED GAIN VECTORS AND ASSOCIATED METHODS - A communications receiver includes an antenna, and a burst signal acquisition circuit coupled to the antenna to detect a burst signal received over a wireless communications channel. The burst signal has a burst structure that includes channel-corrupted known preamble bits, channel-corrupted known probe bits and channel-corrupted unknown data bits. A channel estimator is coupled to the burst signal acquisition circuit to generate a-priori a gain vector based on uncorrupted known probe bits, and to perform a recursive least squares (RLS) operation to determine an impulse response of the wireless communications channel based on the channel-corrupted known probe bits and the gain vector. A maximum likelihood sequence estimator (MLSE) or equalizer is coupled to the channel estimator and the burst signal acquisition circuit. | 05-08-2014 |
