Patent CA-2265800-A1 (CA)
Inventor: ROBERTAZZI THOMAS G
IPC: G06F15/177
Filed: 1997-09-09
Abstract: A load sharing system (100) which minimizes overal costs by assigning segments of a divisible load to distributed processors (105, 107, 109) based on the monetary cost of each processor. The distributed processors are connected to a network such as a local area network (114) or the Internet. A controller (103) divides a divisible load and assigns each segment of the load to a processor based on the processor's monetary cost which is a function of its operating cost and its processing speed. The allocation is then optimized by transferring portions of the load from the expensive processors to the cheaper processor while maintaining an acceptable finish time for all processing. The optimization can also be performed for minimizing the finish time of the processors within a cost constraint.

Patent CA-2272602-A1 (CA)
Inventor: RAWLINGS DIANE C
IPC: C09J7/24
Filed: 1997-12-19
Abstract: Increasingly stringent environmental restrictions make it challenging to apply coatings (i.e., paint) by conventional processes like spray painting because of the volatile solvents and hazardous pigments. The environmental scrutiny is particularly focused upon conventional corrosion protection surface treatments, especially chromated primers and conversion coatings. We apply appliques (10) to provide a vapor barrier over the substrate to provide corrosion protection. We can make curved appliques on a family of molds of different Gaussian curvature and thereby avoid making a "splash" mold of the surface of interest to create the appliques. Using curved appliques reduces ridges, creases, or gaps that sometimes otherwise occur with attempts to cover a surface with complex curvature with flat (planar) appliques.

Abstract: A platform for implementing interactive voice response (IVR) applications over the Internet or other type of network includes a speech synthesizer, a grammar generator and a speech recognizer. The speech synthesizer generates speech which characterizes the structure and content of a web page retrieved over the network. The speech is delivered to a user via a telephone or other type of audio interface device. The grammar generator utilizes textual information parsed from the retrieved web page to produce a grammar. The grammar is supplied to the speech recognizer and used to interpret voice commands and other speech input generated by the user. The platform may also include a voice processor which determines which of a number of predefined models best characterized a given retrieved page, such that the process of generating an appropriate verbal description of the page is considerably simplified. The speech synthesizer, grammar generator, speech recognizer and other elements of the IVR platform may be operated by a Internet Service Provider (ISP), thereby allowing the general Internet population to create interactive voice response applications without acquiring their own IVR equipment.

Patent CA-2288311-A1 (CA)
Inventor: HAYNES CHARLES
IPC: H04L12/16
Filed: 1999-11-03
Abstract: Escrow Electronic Commerce Process adds new methods to standard electronic commerce (e-commerce) processes. In standard electronic commerce a customer "visits" a merchant's web site and selects items to purchase, selects a shiping method, then enters their credit card payment identification numbers and selects a "submit" button to send this information to the merchant's sever computer, usually the selecting of the "submit" button causes a Secure Socket Layer (SSL) to open between the customer's computer and the merchants server computer, encrypts the data string and sends it to the merchants server compute where the Credit Card information is verified and if "approved" then the order is processed as the merchant has the custom's funds via their merchant credit card bank account. A problem has arisen, mainly with small businesses, that some merchants have kept the customer's money and have not shipped the product, or have shipped the product and the shipment has not arrived at the customer's address. Also, the merchant has access to the customer's credit card information. Since electronic commerce is suitable for transactions between a customer and a merchant, who are unknown, to each other and at great distances from each other, the customer's fear that products ordered and paid for may not be shipped and their concern over giving credit card information to numerous merchants has resulted in loss of customs confidence in doing electronic commerce, particularly with small businesses. The escrow electronic commerce process adds new methods and modifies the standard electronic commerce process to ensure that the funds are not obtainable by the merchant until the customer has received the shipment by interjecting a third party, called the Escrow Agent who is a "certified credit card processor" into the standard electronic commerce process such that the credit card information is processed by the Escrow Agent and if "approved" then the Escrow Agent "holds" the funds and notifies the merchant that a specific customer has made an order for specific product(s) products to be delivered to a specific address and that the funds have been verified and are being "held' for the merchant pending shipment of the goods to the customer, when the shipment has been verified the Escrow Agent releases the funds to the merchant. Finally, when the order transaction is complete the Escrow Agent destroys the custom's credit card information so the customer's concern for credit card security is removed.
