  • Method and apparatus for transmitting LTE waveforms in shared spectrum by carrier sensing
    Patent number: 11943629
    Abstract: A method of operating a long term evolution (LTE) communication system on a shared frequency spectrum is disclosed. A user equipment (UE) is initialized on an LTE frequency band. A base station (eNB) monitors the shared frequency spectrum to determine if it is BUSY. The eNB transmits to the UE on the shared frequency spectrum if it is not BUSY. The eNB waits for a first time if it is BUSY and directs the UE to vacate the shared frequency spectrum after the first time.

  • Fiber optic fluid probe
    Patent number: 7382458
    Abstract: A fiber optic fluid probe is employed in determining characteristics of a fluid or solid dispersed in the fluid into which the probe is immersed. The probe transmits electromagnetic radiation from a source by way of one or more fiber optic fibers and into the fluid, and then senses how the electromagnetic radiation interacts with the fluid. The optical signal returned from the probe, by way of fiber optic cables, is interrogated by an electronic instrument, which correlates the optical response to fluid properties and/or characteristics.
