    Abstract: To avoid signal jamming, a method is provided for selecting a dwell channel on a receiver in a frequency hopping communication system. The method includes: measuring a noise level on channels over which a data signal is received at the receiver; selecting a dwell channel based on the estimated noise levels, where the dwell channel having the lowest noise level amongst a group of permissible channels over which to acquire a signal from a transmitter; and tuning the receiver to the selected dwell channel during a search state in which the receiver attempts to synchronize with a transmitter.

    Abstract: A device to induce a fire tornado with a swirling vortex of flames rising into the air. The device includes a flame element and a series of nozzles that deliver the flow of air into the area of the flame element. The air flow is such that eddy currents are created, which along with the heat of the flames, results in inducing the fire tornado.
