Abstract: A method and system for monitoring users on one or more computer networks, disassociating personally identifiable information from the collected data, and storing it in a database so that the privacy of the users is protected. The system receives a user identifier and uses it to creates an anonymized identifier, defined as a user identifier stripped of all personally identifiable information. The anonymized identifier is then associated with one or more users' computer network transactions. The data is stored by a collection engine and then aggregated to a central database server across a computer network.

Abstract: A method and system for monitoring users on one or more computer networks, disassociating personally identifiable information from the collected data, and storing it in a database so that the privacy of the users is protected. The system includes monitoring transactions at both a client and at a server, collecting network transaction data, and aggregating the data collected at the client and at the server. The system receives a user identifier and uses it to create an anonymized identifier. The anonymized identifier is then associated with one or more users' computer network transactions. The data is stored by a collection engine and then aggregated to a central database server across a computer network.

Abstract: For analysis of small quatities of target analytes in an environment, the gas flow can be delivered to a suitably fast analyzer and their concentration determined in a time period whose duration is dependent on the analyte, its concentration and the phase separation properties. A device having a sorbent bed that is essentially concentric with a passage way containing thermal fluid is used to concentrate the target analyte.
