Title: Process for the preparation of anionic clay
Inventor: JONES WILLIAM
IPC: C01F7/785
Filed: 2002-02-05
Abstract: This invention relates to a process for preparing a 3R1-type crystalline anionic clay comprising the steps of: a) preparing an aqueous precursor mixture comprising aluminium trihydrate or a thermally treated form thereof and a magnesium source, the magnesium source being milled before use of when present in the precursor mixture; b) aging the precursor mixture at temperatures in the range 30~ - 100 ~C to obtain the crystalline clay produc t; and c) optionally shaping the product of step b. Milling of the magnesium source, either alone or in combination with the (thermally treated) aluminiu m trihydrate, results in a faster reaction and higher conversion to anionic clay. The resulting anionic clay can be obtained by simply drying the slurry retrieved from the reactor. There is no need for washing or filtering, and a wide range of ratios of Mg/Al in the reaction product is possible.

Title: System and apparatus for critical time to transmit in a non connected vending machine operated by mobile phone
Inventor: TANABIAN MOHAMMAD
IPC: G06Q20/32
Filed: 2004-01-21
Abstract: This invention addresses the problem of inventory management at a point of purchase (e.g., a vending machine) referred to as VS 110, by means of a mobile user equipment 150, (i.e., mobile phone or connected PDA). A summary of the inventory information from the vending machine is prepared and transmitted with each transaction.  The model is based on a "critical time to transmit" logic. When the system judges that the time is critical to transmit the summary of its inventory data, it generates a signal (audio and/or visual) to attract customers with mobile phone to get discounted (or free) products. By fulfilling a transaction with the mobile phone, the customer also conveys the critical information into the back-end server which will later be used to optimize the inventory management.   In this invention, we do not assume direct connectivity of the VS 110. The connection between the VS 110 and the service center (SC) 170 is indirectly created with the user's equipment through the messages that are securely exchanged.

Filed: 2002-08-01
Abstract: A method and a system for performing financial transactions between parties having clients (15a, 15b) with an electronic messaging facility and a banking account facility with a financial institution. Each party has an electronic messaging address (CIN) associated with the electronic messaging facility and a banking account number (CAN) associated with the banking account facility (27) thereof. A financial service provider server (13) is interfaced with the electronic messaging facility to handle communications between the clients (15a, 15b) of the parties and is also interfaced with the banking account facilities (27) of the parties to perform the financial transaction. The electronic messaging address (CIN) of each party is linked with the banking account facility therefor, and thus the banking account number(s) (CAN) thereof, within a database (45) associated with the server (13) to facilitate the financial transaction. The server (13) undertakes an authentication process within one and/or the other party using the electronic messaging facility requiring confirmation of a PIN also stored in the database (45). The authentication process is characterised by the server (13) providing the client (15a) of the one party instigating the financial transaction with a different electronic messaging address to "reply to" when requesting the PIN, from the original electronic messaging address of the server (13) used by that same party to initiate the financial transaction, to enhance the security of the transaction.

Title: Algorithm for accurate three-dimensional reconstruction of non-linear implanted medical devices in vivo
Inventor: BAXTER WILLIAM W III
IPC: G06T3/00
Filed: 2003-03-06
Abstract: A computer-implemented software system and method for performing dynamic, three-dimensional reconstruction of a non-linear implanted medical device from biplane x-ray images. A biplane radiographic image of a calibration object is used to compute the relationship between a three-dimensional coordinate system and the two-dimensional coordinate system for each image plane. These relationships are used to superimpose a three-dimensional device model onto each biplane image pair. An iterative, active contour model, initiated by a user-specified curved template, solves for the three-dimensional device centerline coordinates. Device reconstruction is repeated at each time point associated with each image pair. Algorithm output is available for test development, structural analysis or other clinically relevant applications.
