Abstract: The present disclosure relates to a detection system for detecting a failure in a fluid path of a fluid system, the detection system including: at least one pipe comprising a pipe wall which defines a fluid path for the transfer of fluid and at least one electrically conductive element extending along the at least one pipe and which forms an electrical signal path for a first electrical signal which indicates a state of the at least one pipe; and, an electrical terminal electrically connected to the at least one electrically conductive element so that the first electrical signal is transmitted to the electrical terminal via the electrical signal path.

Abstract: A quick connector for permanently locked, non-disconnectable receipt of a tubular male insertion member having a lock feature, and assembly therewith is provided. The connector includes a housing having a tubular wall with inner and outer surfaces extending between opposite ends with a locking feature extending into the inner surface. The inner surface bounds a through bore having an annular shoulder. A retaining member has an annular retainer wall with inner and outer surfaces. The retaining member outer surface is sized for receipt in the through bore of the housing wall. At least one locking member extends radially outwardly from the retainer wall outer surface for lock engagement with the locking feature to prevent relative axial movement between the housing wall and the retaining member. The retainer wall has at least one locking finger extending radially inwardly for locked engagement with the lock feature of the tubular male insertion member.

Abstract: A method is provided for offering and distributing digital coupons from promoters to users via a network. The method includes the steps of receiving the digital coupons, storing them on a central computer, and associating them with a product identifier. The user selects a selected product identifier, and the digital coupons associated with the selected product identifier are then transmitted to the user, who can then select a selected digital coupon, for use. The promoter pays a fee for the placement of and/or use of each of the digital coupons.

Abstract: A coupon system has a central computer, an ad placement program operably installed on the central computer, and a master coupon program operably installed on the central computer. The ad placement program receives the coupons from the promoters via the network, associates each of the coupons with at least one UPC identifying the product(s), and determines a price for placement of and/or use of each of the coupons in association with the at least one UPC. The master coupon program transmits the coupons to the users with reference to a selected UPC received from a user.
