| 20090189070 | ION MOBILITY SPECTROMETER INSTRUMENT AND METHOD OF OPERATING SAME - An ion mobility spectrometer instrument has a drift tube that is partitioned into a plurality of cascaded drift tube segments. A number of electric field activation sources may each be coupled to one or more of the plurality of drift tube segments. A control circuit is configured to control operation of the number of electric field activation sources in a manner that applies switched electric fields at a specified switching rate to the drift tube segments to thereby produce at the ion outlet only ions having a predefined ion mobility or range of ion mobilities. | 07-30-2009 |

| 20110121171 | ION MOBILITY SPECTROMETER INSTRUMENT AND METHOD OF OPERATION - An ion mobility spectrometer instrument has a drift tube that is partitioned into a plurality of cascaded drift tube segments. A number of electric field activation sources may each be coupled to one or more of the plurality of drift tube segments. A control circuit is configured to control operation of the number of electric field activation sources in a manner that sequentially applies electric fields to the drift tube segments to allow only ions having a predefined ion mobility or range of ion mobilities to travel through the drift tube. The drift tube segments may define a linear drift tube or a closed drift tube with a continuous ion travel path. Techniques are disclosed for operating the ion mobility spectrometer to produce highly resolved ion mobility spectra. | 05-26-2011 |

| 20100114531 | Evaluating Service Level Agreement Violations - A technique for evaluating service level agreement (SLA) violations occurring in a computing system with agreed-upon model for exemptions is provided. The technique includes storing in a memory a model of the SLA and identifying occurrence of an SLA violation in a computing system that is providing services under the SLA. Based on the stored model, the technique further determines if the SLA violation is exempted from a penalty. | 05-06-2010 |

| 20100071723 | Reusable filter and regeneration station - A combination of a reusable fluid filter and a cleaning/regeneration apparatus that cleans a used filter and returns it to like-new condition for reuse. The filter comprises a container and a filter medium, the latter of which is a combination of coarse and fine wire mesh layers. The wire mesh may be cleaned and returned to usable condition using the regeneration station. The regeneration station comprises a reservoir having a cleaning medium, a filter mount, a compressed gas inlet, and a circulating pump supplying cleaning medium to the filter to be cleaned. | 03-25-2010 |
