Abstract: Methods, systems, and techniques for network resource attack detection using a client identifier. A server receives from a device the client identifier and user credentials. The client identifier and user credentials are assessed to determine their authenticity. If one or both of the credentials and identifier are inauthentic, the device does not learn from the server which of the identifier and credentials have been found to be inauthentic. When at least one of the identifier and credentials are inauthentic, the device that sent them is assessed to determine whether it is an attacker of the network resource. If the device is determined to be an attacker, one or both of prophylactic and remedial action is taken in response.

Abstract: A temperature activated pressure relief mechanism for a flashlight or other battery containing device includes a watertight sealed flashlight housing which has an opening which extends from an outer surface to and inner surface of the housing. A metallic eyelet having an eyelet opening and having a cylindrical body sized to fit is placed tightly into the housing opening. A fusible plug of a suitable alloy material placed into said eyelet opening so that when said alloy material reaches the alloy melting point, said material will melt and flow at least partially out of the eyelet opening allowing gas pressure from within the sealed flashlight housing to vent to outside the sealed housing through the eyelet opening.

Abstract: There is disclosed herein a solution for removing a sulphur compound or carbon dioxide from a fluid and methods for its use, said solution comprising sulphuric acid, a metal at between about 0.05 to 10 percent by weight, an amine at between about 10 to 80 percent by volume and water. In one aspect, the sulphuric acid is in the form of a chelating agent and in another it is in the form of a derivative of a sulphur-based acidic compound. The sulphur compound may be hydrogen sulphide, carbonyl sulphide or a mercaptan. In one aspect, the method is practiced at temperatures significantly below zero. In another aspect, this invention is an acid/amine solution comprising sulphuric acid, sulphuric acid in the form of a chelating agent, or a.-derivative of a sulphur-based acidic compound and monoethanolamine. This solution may be used as a source of monoethanolamine.
