A transaction system for performing secure transactions over a communication network includes (i) a merchant server system including a computer processor and associated memory, the merchant server system offering items for sale; (ii) a buyer system including a computer processor and associated memory, the buyer system being selectively couplable to the merchant server system over the communication network to initiate a transaction, wherein, during the transaction, the buyer system selects one or more of the items for purchase; (iii) a security server system including a computer processor and associated memory and an encryption device, the security server system receiving buyer information from the buyer system, encrypting the buyer information in an encryption key that prevents the merchant server system from decrypting the buyer information, and transferring the encrypted buyer information to the merchant server system; and (iv) a third server system including a computer processor and associated memory, the third server system being selectively couplable to the merchant server system, wherein the merchant server system transmits at least a portion of the encrypted buyer information to the third server system for processing during the transaction.

A method that analyzes mass spectra using a digital computer is disclosed. The method includes entering into a digital computer a data set obtained from mass spectra from a plurality of samples. Each sample is, or is to be assigned to a class within a class set having two or more classes and each class is characterized by a different biological status. A classification model is then formed. The classification model discriminates between the classes in the class set.

Method for analyzing mass spectra

A method and system of detecting mass to charge ratio of ions. The method includes producing charged ions in a vacuum, accelerating the charged ions in an electric field into a free flight tube and detecting the charged ions at a detector associated with the free flight tube. A control system selects a bandwidth for filtering a signal produced by the detector and the signal produced by the detector is then filtered with a variable width digital filter based upon the selected bandwidth. The bandwidth for filtering the signal may be selected from a look-up table within the control system based upon the mass to charge ratio of an ion of interest. Alternatively, a peak bandwidth within the signal produced by the detector may be determined and the signal produced by the detector may then be filtered with the variable width digital filter based upon the determined peak bandwidth.
