Abstract: The 802.11b wireless LAN specification is compromised by the weaknesses of WEP. The invnetion routes wireless transmissions to the LAN via a firewall or VPN gateway and encrypts them.

Abstract: An internet server is controlled wherein the server receives a hypertext transfer protocol file request from a web browser over the internet and any identification signal included with the hypertext transfer protocol file request. The identification signal is compared with one or more predetermined identification signals and depending upon the result of the comparison a file may be transmitted from the server to the web browser.

Abstract: A technique for assembling semiconductor devices in which semiconductor elements, especially lasers or LEDs, are mounted on a first packaging element such as a heat spreader that is mounted on a second packaging element such as a heat sink. Handling of solder preforms is avoided by coating at least one of each of the pairs of surfaces to be brought into contact with a layer of solder and heating the assembly to melt both solder layers in a single operation. In a preferred embodiment a heat spreader is coated in solder on both sides and interposed between a semiconductor element and a heat sink and the assembly is heated. Molybdenum may be used as a layer to aid wetting and adhesion and gold/tin solder may be used. Slightly different solidification temperatures and compositons for the layers may result from different take up of metallization layers from the components into the solder.
