  • Patent number: 9788182
    Abstract: A system for wireless communication comprising a plurality of wireless stations; each station configured to receive and transmit communications on at least one channel, each station comprising at least one processor and at least one memory operatively connected to the at least one processor; the at least one processor being configured to sense communications on the at least one channel and to wait a predetermined number of units of delay before transmitting a communication on the channel; the predetermined number of units of delay before transmission of the next communication being operatively associated with communications by the respective units.
    Type: Grant
    Filed: June 3, 2015
    Date of Patent: October 10, 2017
    Assignee: The United States of America as represented by the Secretary of the Army

  • Patent number: 4314670
    Abstract: A method of atomization control and related gas atomizing nozzles are described which enable variation of the degree of atomization, the liquid and gas flow rates and the atmospheric spray dilution. Varying the thickness of flowing liquid and adjacent atomizing gas sheets varies spray droplet size and atmospheric spray dilution. Transverse sheet size is varied to change nozzle capacity. Annular and linear sheet forming nozzles are described. Nozzles are also described with flexible divider walls whereby thickness of the flowing sheets may be varied by altering relative flow pressures.
