  • Patent number: 10119703
    Abstract: Methods for vaporizing hydrocarbon fuel and delivering the hydrocarbon fuel in either a vaporized phase or a supercritical phase to, for example, a combustion chamber are provided herein. A method of vaporizing a hydrocarbon fuel, wherein the hydrocarbon fuel is in a liquid phase at a first temperature and a first pressure, and wherein the first temperature of the liquid phase hydrocarbon fuel is less than its intrinsic oxidation or endothermic reaction temperature, the method may include lowering a pressure of the liquid phase hydrocarbon fuel from the first pressure to a second pressure; and heating the liquid phase hydrocarbon fuel from the first temperature to a second temperature, wherein the hydrocarbon fuel at the second temperature and the second pressure is in a substantially completely vaporized phase substantially without thermally oxidizing the hydrocarbon fuel, and wherein the hydrocarbon fuel in the substantially completely vaporized phase does not form carbonaceous contaminants.

  • Patent number: 8571004
    Abstract: A mobile ad-hoc network includes a plurality of N mobile nodes and wireless communication links connecting the mobile nodes, which each include a communications device for transmitting and routing data packets wirelessly to other mobile nodes via the wireless communication links in accordance with a time division multiple access (TDMA) data transmission protocol using a TDMA epoch that is divided into a beacon interval, digital voice interval and digital data interval. The mobile nodes monitor channel conditions using the beacon, digital voice and digital data intervals and provide a network conductivity performance as valid receptions occur within mobile nodes. A data rate is calculated and set for other N?1 mobile nodes using monitored channel conditions for the beacon, digital voice and digital data intervals.

  • Patent number: 8187598
    Abstract: Methods and compositions for regulating immunity are disclosed. For enhancing an immune response, agents that inhibit OX-2 are administered. Such methods are useful in treating cancer. For suppressing an immune response, an OX-2 protein or a nucleic acid encoding an OX-2 protein is administered. Such methods are useful in preventing graft rejection, fetal loss, autoimmune disease, allergies and in inducing tumor cell growth.

  • Publication number: 20120017707
    Abstract: The presently disclosed systems and methods may be utilized in connection with several different sensor suites for detecting objects in the ground. Such systems and methods may be utilized in conjunction with a variety of military and commercial vehicles. In various embodiments, a sensing system may be carried by a vehicle in a stowed or deployed position. While in the stowed position, a segmented boom may have a relatively small vertical profile in comparison to the length of the boom when fully extended. According to various embodiments, in the deployed position the height of the sensor may be controlled to avoid obstructions. A hoist connected to the boom may be utilized to move the boom between the deployed and stowed positions.
