20130007250 | CONTROL OF COMMUNICATION PORTS OF COMPUTING DEVICES USING POLICY-BASED DECISIONS - In a computing system environment, an arrangement of computing devices includes multiple layers behind a content flow director, such as an L4 switch in a web service. In a computing device of an outermost layer directly communicating with the content flow director, a communications port is conditionally enabled upon policy being met or exceeded in the computing system environment behind the content flow director. If unmet, the communications port is disabled, if already enabled, or prevented from becoming enabled, if not otherwise already enabled. In this manner, policy establishes port enablement. In certain aspects, policy determinations include determining a time of response, a quality of service check or a pass/fail condition of the one of the computing devices. Policy is also easily implemented as remote or local computer executable instructions on the computing devices. Representative computing devices include switches, such as L4 switches, routers, servers, repeaters, adapters or the like. | 01-03-2013 |

20090020697 | Enhanced Resolution Mass Spectrometer and Mass Spectrometry Method - A mass spectrum is generated by a process in which, from a mass scan signal comprising original samples defining a peak, a subset of the original samples defining the peak is selected. One or more synthesized samples are synthesized from the subset of the original samples. The one or more synthesized samples provide a temporal resolution greater than the temporal resolution of the original samples. The one or more synthesized samples are summed with respective temporally-aligned accumulated samples to produce the mass spectrum. The accumulated samples are obtained from mass scan signals generated during respective previously-performed mass scan operations. | 01-22-2009 |

20150219598 | FAST METHOD FOR MEASURING COLLISION CROSS SECTION OF IONS UTILIZING ION MOBILITY SPECTROMETRY - The collision cross section (CCS) of a sample ion may be calculated by measuring a total drift time taken by the sample ion to travel through an ion mobility spectrometry drift cell to an ion detector. The CCS may be calculated based on the total drift time measured, and on a proportionality coefficient that defines the time taken by the sample ion to travel through a mobility dominated region between the drift cell and the detector. The proportionality coefficient may be determined from measuring the total drift times of reference ions. Calculation of the CCS of the sample ion may also be based on a proportionality coefficient that defines the time taken by the sample ion to travel through a mobility-independent region where the velocity of the ion depends on the electrostatic field strength, mass and the charge state of the ion. | 08-06-2015 |
