Abstract: A coupon redemption card and tracking system includes a credit card size redemption coupon card used by the customer, and a tracking sheet used by the redemption center such as a restaurant. The redemption card has a plurality of mini coupons, which can be peeled off individually. Each redeemed coupon is affixed to a tracking sheet. The tracking system facilitates the accounting and inventory of redeemed coupons. The coupon card is formed as two laminated layers of special paper joined together by a layer of adhesive material, and a layer of clear plastic film on the top face of the card. The base layer is fabricated from a special paper. An adhesive coating is applied to one side of the base layer. The peel off coupon layer is affixed to the adhesive coating. The finished layered sheet is printed on both sides, die--cut on the coupon side, and then laminated with the film on the other side. Each coupon that is removed from the card has adhesive to adhere the coupon to the tracking sheet. The small size of the mini coupons is convenient for the card holder and the redemption center. The system can be used wherever one has to keep track of various redeemable coupons. A memory chip or a microprocessor chip is adhered to the card to form a memory smart card. The microprocessor chip is programmed to contain information about the card so that a chip reader can read the information about the card.

Title: Anonymous web site user information communication method
Inventor: RESSL MICHAEL G
IPC: G06F21/31
Filed: 1999-11-30
Granted: 2005-08-09
Abstract: A method of anonymously providing user information while browsing internet web sites by inputting a data information record into storage, dynamically generating a user alias, linking the user alias with the user data record to form a user information record (UIR) and then transmitting the anonymous user information record automatically or in response to user commands. This alias identification is transmitted to a remote internet operating computer of a web site that receives the information inputted for collecting information, such as statistical or demographic information. Once the combined UIR has been formed, a communication protocol of the invention allows the user to deliver the UIR to any web site that is accessed. The protocol of the invention also allows the web site operator to read the UIR and aggregate any information it desires about the user. However, as noted, the web site can only gain access to the user's alias identification in combination with the user data.  In this way the web site is enabled to collect general demographic information about its user base while being isolated from the true identity of the user. With such privacy the quality of the demographic information can be improved and the statistical reliability is improved by detection of repeat hits by the same user.

Inventor: HART JAMES E
IPC: B60T17/04
Filed: 2000-02-16
Granted: 2004-05-04
Abstract: A test connector enables measurement of pressures contained within a body. The body houses check valves and includes studs to attach a cover to a head of the body. Removal of the cover renders the check valves accessible. The check valves are normally compressed against valve seats formed in the head but when moved away from their seats provide access to the pressures. The test connector includes a contact plate, a support plate, two springs sandwiched therebetween and two double flanged nuts. Each spring is disposed so that it is axially aligned with throughholes defined in the plates. Each nut has its middle section disposed coaxially within one of the springs and its flanged ends keep the plates in proximity to each other while the springs seek to force them apart.      Hollow plungers have one end seated in plunger bores in the support plate with the other end free to slide through flow bores in the contact plate. As the nuts are initially threaded onto the studs, the contact plate soon seals against the head without the plungers emerging from the flow bores. As the nuts are further threaded onto the studs, the support plate moves toward the contact plate thereby further compressing the springs and eventually forcing the plungers to emerge from the flow bores to unseat the check valves.      This permits each of the pressures contained thereby to communicate through the hollow plungers and out the plunger bores thereby allowing access to the pressures within the body.
