Abstract: A heater assembly for a tank 1 for storing a fluid reducing agent 2 for reducing harmful components in the exhaust gas of internal combustion engines, said heater assembly comprising a primary enclosure 5 which can be deployed in a lower portion of the tank 1 and which has an outlet opening 12 in a predetermined region 11 of the primary enclosure; and a heating device 18 for heating the reducing agent 2, said heating device 18 being disposed in the predetermined region 11 of the primary enclosure 5.

Abstract: A system (100) enables a customer (103) to order goods via the Internet using a browsing device (104). The system includes at least one web server (106). The system further includes at least one DNS server (105) within a DNS system, which is configured to establish an association between goods (107), at least one corresponding domain name (102), and the web server (106). A request issued to the DNS server (105) to resolve the domain name (102) results in a response providing an Internet address of the web server (106). The web server (106) is configured to respond to a connection request initiated using the Internet address and a corresponding network resource locator including the domain name (102) by executing an ordering process. In various embodiments, the network resource locator may include a product identifier within the domain name, or within a distinct component thereof.

Abstract: A method of identifying altered order critical data in a system for conducting electronic commerce over a public data network in which orders are placed by a customer using a computer. The method includes the step of transmitting an electronic order of the customer over the public data network from the customer computer to a validation server. The validation server validates order critical data included in the order by executing the steps of verifying the order critical data, and generating an indication of the validity or otherwise of the order critical data. The method enables, for example, orders generated by untrusted devices, such as a customer computer, to be verified by a trusted validation server thereby improving the security of electronic commerce systems employing client-side ordering.
