    • An overcurrent protection system which will give a rapid response to overcurrents which cause a reduction in the voltage across the load, e.g. a partial or complete short across the load, and is particularly suitable for protecting circuits against relatively small overcurrents, comprising: a circuit interruption element which, in the operating circuit, is connected in series between the electrical power supply and the electrical load, and which has (1) a closed state which permits the flow of a normal current, I.sub.NORMAL, through the circuit interruption element, and (2) an open state which permits the flow of at most a reduced current, substantially less than I.sub.NORMAL, through the circuit interruption element; a control element which, in the operating circuit, is connected in parallel with the load, and which has (1)(i) an on state, when the voltage across the control element is a normal voltage, V.sub.NORMAL, and (ii) is converted to an off state, when the voltage across the control element falls to a value V.sub.FAULT, or less, and (2) is functionally linked to the circuit interruption element so that when the control element is in the on state, the circuit interruption element is in the closed state, and when the control element is in the off state, the circuit interruption element is in the open state; and a bypass element which (1) is connected in parallel with the circuit interruption element, and (2) has (i) a start-up state such that, if the circuit interruption element is in the fault state and a current I.sub.NORMAL is passed through the bypass element, the voltage across the control element is greater than V.sub.FAULT, and (ii) a stopped state such that if the circuit interruption element is in the fault state as a result of the voltage across the control element having fallen to a value V.sub.FAULT or less, the current through the bypass element is such that the voltage across the control element remains at a value of V.sub.FAULT or less.

    • The method and system of the present invention provides an improved technique for replacing, implementing and managing computer-related assets. A technician accesses the World Wide Web through a user's computer. The information resident on the computer, including information regarding the computer and the user's preferences, are downloaded to a remote storage medium through the World Wide Web. Once downloaded, all information may be removed from the user's computer. Subsequently, the technician accesses another computer such as, for example, a new computer that has been assigned to the same user. The technician accesses the World Wide Web through the new computer and downloads the information previously stored on the remote storage medium. This information can then be used to install the user's prior applications, settings and preferences on the new computer.

    • The invention provides a multi-polymer hydrogel article having a first polymeric, water-swellable material and a second polymeric material, organized such that a first region substantially comprises the first polymeric, water-swellable material, a second region adjacent the first region comprises a mixture of the first polymeric, water-swellable material and the second polymeric material, and a third region adjacent the second region substantially comprises the second polymeric material. The article exhibits an increasing concentration gradient of the second polymeric material moving from the first region, through the second region, to the third region. The invention also provides methods for forming a multi-polymer hydrogel article by (a) forming a hydrogel structure using a first polymeric, water-swellable material, (b) creating an aerogel structure having a plurality of open pores by dehydrating the hydrogel structure, (c) contacting the aerogel structure with a second polymeric material to incorporate the second polymeric material into at least a portion of the plurality of open pores to form the multi-polymer hydrogel article, and (d) rehydrating the multi-polymer hydrogel article.
