Abstract: Multiple SQUID magnetometers that include at least two SQUID loops, each of which is composed of at least two Josephson Junctions connected in parallel with superconducting wires, are provided. The SQUID loops are fabricated such that they share a common Josephson Junction. Devices and application that employ the multiple SQUID magnetometers are also provided.

Abstract: Mobile clients can execute IPv6 applications in an IPv4 environment without the need for any specialized IPv6 hardware or upgrades to the network infrastructure. The architecture provides a seamless, disruption-free connectivity experience for mobile clients. Mobile clients are automatically connected to other mobile clients irrespective of their network connectively, whether wireless, wire line, IPv4, IPv6, public or private. Mobile clients communicate with other mobile clients using a secure, end-to-end IPv6 tunnel. This creates a persistent VPN connection between two clients using software.

Abstract: Apparatus and method for drying the seal area (316) of a contact lens blister package (300) prior to affixing a lidstock to the seal area (316) includes a vacuum block (54) to which one or more vacuum heads (50) are removably mounted. The vacuum heads (50) include vacuum tips (52) which engage and circumscribe the seal area (316) removing moisture therefrom. Should a vacuum head (50) become damaged, it is quickly and easily replaceable upon the vacuum block (54).

Abstract: There is described a method of and a fuel economizer device for reducing the fuel comsumption of an internal combustion engine. The device is in the form of a body having an outlet to the engine and a pair of inlets for admission of additional air. The inlets are controlled by pressure operated valves.
