  • Patent number: 8365688
    Abstract: A method and reactor suitable for reformation of fuels at low temperatures is disclosed. The method includes introducing an oxidized porous metal felts with a catalyst powder in a reaction chamber having a heat exchange relationship with a heat-providing chamber, vaporizing a liquid mixture of alcohol and water using an Inconel tubing, and introducing the vaporized liquid into the reaction chamber for producing a methane gas. The fuel reforming reactor includes a heat-providing chamber in a heat exchange relationship with at least one reaction chamber. Each reaction chamber having an aluminum shim lining on at least one interior surface. Each reaction chamber accommodating a catalyst powder and an oxidized porous metal felt. The catalyst powder loaded onto the oxidized porous metal felt to facilitate production of methane gas from alcohol for use with the internal combustion engine.

  • Patent number: 7738865
    Abstract: Described are apparatus and methods for adapting a mobile unit to communication requirements of a particular country or geographic region. A wireless local area network communications system may include access points and remote terminals. Remote terminals may use country-specific information in messages from an access point to adapt to the communications requirements of the country in which the access point is operating. The country-specific information may be in a broadcast transmission or a message sent in reply to a remote terminal probe message. The country-specific information may include operating requirements such as channel information, power information, country name, modulation information, etc.

  • Patent number: 6484029
    Abstract: A method and apparatus for automatically adapting a mobile unit to the communications requirements of a particular country or geographic region is provided. A wireless data communication network located in a particular country or geographic region includes one or more access points for communicating with the mobile unit. The mobile unit receives from an access point an announcement message broadcast. The message has a unique frequency characteristic associated with the geographic location of the access point from which it was broadcast. The mobile unit then determines an allowable frequency set for use in the country or geographic location associated with the access point. The mobile unit adjusts its frequency set to operate o the allowable frequency set. The mobile unit may also adjust others of its operating parameters in a similar fashion.
