Patent CA-2303130-A1 (CA)
Inventor: SCHMELING BURKHARD
IPC: B29B17/00
Filed: 1998-09-10
Abstract: The invention relates to a method for processing tires, producing products comprised of the tire material and a device for cutting tires and flatly constructed products or bodies e.g. blocks, mats or cords which are produced from cut tires. The invention can be applied especially to reshaping passenger car, truck or aircraft tires that are no longer acceptable for use in transportation into a new foundation as a base material which can be utilized for manufacturing products in multiple areas of the economy. Intermediate products for manufacturing new final products are made out of cut tire rings. The method is characterized in that the tires are separated into a series of segments in such a way that the two side pieces of the wheel tread are separated off and the resulting rings are joined to form new products with one another.

Title: Method and apparatus for authenticating users on a network
Inventor: DATAR RAJENDRA
IPC: H04L29/06
Filed: 2000-05-02
Abstract: A user (12) obtains an electronic credential (14) through a network (18) by first requesting such a credential from a certificate authority (16) which, in response verifies the identity of the user by making an inquiry to a directory (24). Upon successful verification of the user, the certificate authority prompts the user for a first password and the identity of an individual (26) having the authority to vouch for the user.  Thereafter, the certificate authority launches an inquiry to the individual identified by the user. Upon successful authentication of the user by the identified individual (26), the certificate authority provides the user with a second password, and thereafter prompts the user for both passwords. After correct receipt from the user of both passwords, the certificate authority provides the user with the credential, and thereafter erases the two passwords.

Title: Method and device for testing digital protection devices
Inventor: WINTER WILHELM
IPC: G01R31/327
Filed: 1998-09-04
Abstract: The invention relates to a method and configuration for testing digital protection devices in which a data processing energy supply network is emulated by means of pulsed output of digital current and voltage signals.  To this end, utilizing one such method, corresponding currents and voltages are constructed and supplied to a protection device which is to be tested. In order to test protection devices as realistically as possible with comparatively simple data processing equipment, the fetched out digital current and voltage signals (J', U') are first buffered in succession at the beginning of the testing of the protection device (6). After achieving a predetermined consistency of the buffered signals (I z, U z), the respective oldest buffered signals (I z, U z) are read out in a clock-pulse manner and most recent fetched out signals (J', U') are buffered. In the occurrence of a tripping signal, reading out is continued in a pulsed manner and data processing network specific digital current and voltage signals are fetched out and buffered.

Patent CA-2322210-A1 (CA)
Title: System and method for auctioning services over an information exchange network
Inventor: RIEMER THOMAS
IPC: G06Q30/08
Filed: 2000-10-04
Abstract: The present invention is directed to an improved system and method for auctioning services, which overcomes some of the drawbacks in the prior art systems and methods. In accordance with one aspect of the present invention, buyers request and specify at the start of the auction the number of lowest bids the buyers would like to see.  By requesting to see more bids, the buyers would have greater opportunity to evaluate service providers based on factors other than price, thereby encouraging less price competition among providers. By requesting to see fewer bids, the buyers would have less opportunity to evaluate service providers based on factors other than price, thereby encouraging fierce price competition. The number of bids requested by the Buyer is made known to the bidders. The net effect is that the buyers can control the price/quality tradeoff at the onset of the auction process, and encourage the bidders to provide their lowest bids when pricing is important. This lets the buyers make their final decision based on factors in addition to price, at the lowest price possible.     In another aspect of the present invention, a rating system is employed to rate the buyer's transaction history, with respect to their frequency of following through with the bids for jobs that they submitted for auction. This rating system deters those buyers that casually shop for pricing with little chance of following through with the auction. Buyers who frequently submit jobs without executing them will get a low rating. A low rating discourages service providers from bidding, thereby decreasing the competitiveness of an auction and increasing the cost of obtaining the service. Consequently, buyers will be reluctant or discouraged to submit for auctioning jobs that have a low chance of occurring, because it affects their rating. The buyer follow-through ratings give the bidders a better sense of the buyers' commitment prior to deciding on allocating resources to participate in bidding at the auction.   In one embodiment of the present invention, the system and method for auctioning services are implemented over an information exchange network. In a more specific embodiment of the present invention, the information exchange network is the Internet. This facilitates bringing together the many service providers in a centralized auction market using standardized, electronic bid forms to communicate prices publicly, and service providers have a chance to adjust their prices in real time. For purpose of illustrating the inventive concept, the present invention is described using the example of document services, and more particularly printing services.
