Abstract: The present invention provides an apparatus and method for use with a mass spectrometer. The invention provides a mass spectrometer system for non-pneumatic ion production, including a non-pneumatic nanospray ionization source. The nanospray ionization source has a first non-pneumatic ion spray emitter for producing ions; a conduit adjacent to the ion spray emitter, the conduit having an aperture designed for receiving ions from the ion spray emitter; a first electrode for directing the ions from the ion spray emitter toward the aperture of the capillary; and a conduit electrode for directing ions into the conduit; and detector down stream from the capillary for detecting ions produced by the non-pneumatic nanospray ionization source.

Abstract: The present invention provides a method for locating mobile units in a wireless telecommunication network. The method includes determining at least one distance associated with a mobile unit in communication with at least one base station in a wireless telecommunications network, determining a first location based on said at least one distance, and selecting a plurality of second locations based on the first location. The method also includes determining a plurality of likelihoods that the mobile unit is at each of the plurality of second locations.

Abstract: The invention provides a novel, easy to use, hand-operated apparatus for effortlessly loosening the threaded lid of ajar or bottle having a screw-on lid and readily accommodates jars or bottles of different sizes. One form of the invention includes a base having a jar supporting surface, a generally vertically extending guide column connected to the base and a carriage assembly connected to the guide for movement relative to the guide between a first raised position and a second lowered position. Novel features of the invention include the provision of a helical drive screw which drives a jar lid engaging assembly and a novel safety clutch mechanism which prevents the exertion of excessive force on the jar being opened.

Abstract: A data classification system identifies and processes malicious data that may be present in a received data stream. The system includes at least two stages, and a data flow module. The data flow module derives, from an input data stream, a first processed data stream that is transmitted to the first processing stage. The first processing stage derives, from the first processed data stream, a second processed data stream that is transmitted to the second processing stage. The first and second processing stages optionally derive meta data from the data they receive.

Abstract: A method and apparatus for transforming regular expressions into a less resource intensive representation is disclosed. The method and apparatus converts a collection of regular expressions into a multi-level representation in which the memory requirements of the lowest level representation is reduced when compared with a conventional finite state automaton representation. The method and apparatus converts a collection of regular expressions into a collection of segments and a higher level representation in a way that retains the semantics of the original set of regular expressions. This transformation is performed through the use of an intermediate form. The resulting representation and collection admit an implementation which avoids the potentially costly memory requirements of a traditional implementation of the original expressions.

Abstract: The invention provides a multi-inlet sampling device for an ion source. In general, the sampling device contains at least two sample inlet capillaries and a single outlet capillary that are all fluidically connected. A mass spectrometer ion source and a mass spectrometer system containing the multi-inlet sampling device are also provided. The device is readily removed and installed at ambient pressure without venting the mass spectrometer. Also provided by the invention are methods for simultaneously introducing at least two samples into a mass analyzer.

Abstract: A programmable finite state machine (FSM) includes, in part, a first address calculation logic block, a first lookup table, a second address calculation logic block, and a second lookup table. The first address calculation logic block generates an address for the first lookup table based on the received input symbol and the current state. The data stored in first look-up table at the generated address is used by the second address calculation logic block to compute an address for the second lookup table. Data stored in the second lookup table is the next state to which the FSM transitions. The programmable FSMs uses redundant information of the transition table to compress these transitions and thus requires a smaller memory while maintaining a high data throughput. The data in the first and second lookup tables are coded and supplied by a compiler. The FSM operation may optionally be pipelined.

Abstract: The states associated with a programmable state machine are reordered to compress the storage of transitions which define the state machine. To reorder the states, a score is computed and assigned to each of the states. Next, the states are sorted according to their computed scores. In some embodiments, to compute the score for each current state based on the received input symbol, the number of times that the input symbol causes transition to similar states is added. The sum of the scores in each row of the table is representative of the score for the associated current state associated with that row. The states are sorted according to their score and a new state transition table is generated in accordance with the reordered states.

Abstract: The present invention relates generally to variants of target biological molecules (“TBMs”) and to methods of making and using the same to identify ligands of TBMs. More specifically, the invention relates to individual variant TBMs and sets of variant TBMs, each of which represents a modified version of a protein of interest where a thiol has been introduced at or near a site of interest. Ligands of TBMs are identified in part through the formation of a covalent bond between a potential ligand and a reactive thiol on the TBM.
