  • Patent number: 8071957
    Abstract: A soft chemical ionization source can be small, require low power, reliably produce different ions depending on the operating conditions and configuration, and produce ions that ionize many sample chemicals in different phases in air, or solutions, or on surfaces. In one embodiment, an ionization source is comprised of a housing having a center post extending therefrom, a plurality of needles extending from the housing, and a counterelectrode extending around the housing. The plurality of needles and the counterelectrode are each coupled to an electrical supply. The center post and the plurality of needles extend through the counterelectrode. A voltage applied to the plurality of needles and the counterelectrode forms a gas discharge. By changing the dimensional or electrical characteristics of the ionization source elements, singularly, or relative to other sources in an array, the types, ratios among, and quantities of reagent ions can be changed and controlled.

  • Patent number: 8045505
    Abstract: The invention provides a set of mechanisms by which a wireless mobile mesh node equipped with a directional antenna may self form and self adapt its steady-state communications schedule. A link establishment handshake is carried out over an ongoing subtemplate-based discovery scan. During time not reserved for steady-state communications with previously discovered neighbors, nodes continue to search for an establish links with new neighbors. Initial and subsequent bandwidth allocation protocols may be utilized to allow peer nodes to coordinate communication opportunities between the peer nodes without impacting or having knowledge about reservations for communications with other peers. The link establishment and initial bandwidth allocation protocols may be piggy-backed for readily establishing an initial steady-state schedule with a peer upon link establishment without impact on previous steady state reservations by other nodes or on ongoing link establishment attempts elsewhere.

  • Patent number: 8008617
    Abstract: Ions carried in a flowing gas stream are transferred to another gas stream of different composition or purity through an ion selective aperture communicating between the gas streams. The ion selective aperture is formed of a central layer which has an electrically conductive layer on each of its surfaces. One or more open channels extend through the central layer and surface layers allowing physical movement of ions therethrough under the urging and influence of an electric field created by imposing a voltage differential between the conductive surface layers of the ion selective aperture. The gas flow rates of the different gas streams may be independently varied to allow adjustment of ion concentration and flow rate to meet the needs of the ion destination. This device can control sample ion introduction into gas-phase ion detectors, such as ion mobility analyzers, differential mobility analyzers, mass spectrometers, and combinations thereof.

  • Patent number: 7985590
    Abstract: Described herein are methods directed to the use of the nanodot taggants in detection and/or simulation scenarios. The nanodot taggants are based on quantum dots and may be engineered so as to have particular emission and or absorbance spectral characteristics. The nanodots are extremely small, i.e., on the order of nanometers in size, and thus do not, in some cases, behave as particles, but rather are able to be carried along and through structures like a gas.

  • Patent number: 7848541
    Abstract: Acceleration of a set of three frames of video with N movers may be determined by generating an inverse Fourier transformation of a differential phase correlation matrix of the three frames. The resultant acceleration estimate may be integrated with the velocity and offset estimates for the second frame so as to provide an offset estimate for the third frame. The third frame may then be co-registered with a reference frame. This process may be repeated for subsequent frames so that subsequent frames may also be registered to the reference frame so that video jitter that was caused by platform shake may be reduced or eliminated.
