Title: Method for virtual on-demand electronic book
Inventor: HENDRICKS JOHN S
IPC: H04N7/173
Filed: 2000-10-27
Abstract: Method for an electronic book selection and delivery system that distributes text to subscribers. The system provides a means for on-demand and virtual on-demand delivery of electronic books. Specified electronic books may be broadcast to a set of subscribers. Alternatively, a first section of the specified electronic books may be broadcast. A second section of each of the electronic books is then available for later delivery, upon order by a subscriber. The second sections, as well as first sections, and true on-demand electronic books may be loaded into one or more queues. The queues may then be emptied based on a priority model. Electronic books in an on-demand queue may be given priority for delivery over electronic books in other queues.
Patent CA-2391119-A1 (CA)
Inventor: MARACAS GEORGE N
IPC: G01N21/64
Filed: 2000-11-10
Abstract: In a molecule detection system and method, a sample containing target molecules is added to an array of test sites, with each test site containing distinct probe molecules. The probe molecules bind with the target molecules in the sample to form bound complexes. A source illuminates the array of test sites with incident electromagnetic radiation, and an active pixel sensor detects the electromagnetic radiation from the array. To detect the presence of target molecules in the sample, the active pixel sensor detects changes in the optical properties of the test sites that result, either directly or indirectly, from their binding of the probe molecules with the target molecules. The target molecules may also be characterized on the basis of which probe molecules bind to them.

Title: Method, system and data structures for implementing nested databases
Inventor: ANFINDSEN OLE JORGEN
IPC: G06F12/00
Filed: 2001-07-16
Abstract: A method and system for processing and managing requests for concurrent use of data. Nested databases are utilized in order to create different environment s in which the data can be accessed and modified. For each transaction which i s in existence, there is an indication or reference to a database or subdataba se associated with that transaction. There are also data structures which indicate, for each data item at issue, which database or subdatabase is associated with that item. The use of data structures relating the transactions, subdatabases, and data items allows the creation of spheres of  control for the various transactions and subdatabases. Thus, data can be readily shared among a plurality of users. The creation of the subdatabases does not require plural copies of data and the database management system ma y be implemented using one copy of the data, although multiple copies may be utilized, if desired.

Title: Inter-carrier short text message delivery
Inventor: MIDKIFF DAVID
IPC: H04L12/58
Filed: 2003-01-22
Abstract: A method is provided for routing mobile telephone short text messages between different mobile telephone messaging networks, including mobile telephone messaging networks operated by a single carrier (i.e., intra-carrier messaging) or by different carriers (i.e., inter-carrier messaging). The method includes receiving a short text message at a mobile telephone short message gateway operated by a first mobile telephone carrier, the short text message having a destination directory number (DN). The short message gateway determines that the destination directory number (DN) is associated with one of two or more mobile telephone networks. The two or more mobile telephone networks may be operated by the first mobile telephone carrier alone or by the first mobile telephone carrier and another carrier. The short text message is then routed to the appropriate mobile telephone network based upon its destination directory number (DN). In a particular implementation, the short text message is a Short Message Service (SMS) message, and the short message gateway is a Short Message Peer to Peer (SMPP) gateway. The routing of the SMS includes reformatting it to include a Simple Mail Transfer Protocol (SMTP) address of an SMPP gateway of the mobile telephone messaging network to which the SMS message is directed.      The SMS message is then sent as an SMTP message over the Internet.
