  • Patent number: 10501180
    Abstract: A first drone equipped with a high energy Directional Ultrasound Parametric Speaker Array and a second drone equipped with an Acoustic Dispersion Cannon are used to fight wildfire. The first drone is distanced far from a burning flame but in close proximity to a fire target. Both drones are guided by GPS to communicate with remote operators. Once the target is locked, the first drone blasts the target with Amplitude Modulated Ultrasound. The Ultrasound is self-demodulated into a lower frequency audio sound when it encounters a hot flame of richly charged ions. The lowered frequency sound pushes and pulls the flame forward and backward rapidly away from the combustion source, causing it to be disconnected from the flame which instantly cools down and is extinguished. The second drone blasts the combustible source with powerful sonic shockwaves to disperse the still hot particulates further apart to prevent the source being reignited.

  • Patent number: 10017324
    Abstract: A method and system for storing and supplying hydrogen to a hydrogen pipeline in which a compressed hydrogen feed stream is introduced into a salt cavern for storage and a stored hydrogen stream is retrieved from the salt cavern and reintroduced into the hydrogen pipeline. A minimum quantity of stored hydrogen is maintained in the salt cavern to produce a stagnant layer having a carbon dioxide content along the cavern wall and the top of a residual brine layer located within the salt cavern. The compressed hydrogen feed stream is introduced into the salt cavern and the stored hydrogen stream is withdrawn without disturbing the stagnant layer to prevent carbon dioxide contamination from being drawn into the stored hydrogen stream being reintroduced into the hydrogen pipeline. This allows the stored hydrogen stream to be reintroduced into the hydrogen pipeline without carbon dioxide removal.

  • Publication number: 20150021054
    Abstract: A system for providing an automatic fire extinguishing system including a tank filled with an extinguishing agent with a targeting system with independently mounted targeting servos and targeting gimbal to position an emitter. A microcontroller provides control signals to the targeting servos and an actuation valve. A plurality of temperature sensors electrically connected to the microcontroller send temperature data to the microcontroller which calculates target angles and sends the target angle to the targeting gimbal. The emitter is positioned by the targeting servo positioning the targeting gimbal armatures to the target angles. The microcontroller compares sensor temperature data a predetermined temperature value and sends an open signal to the actuation valve when a sensor temperature data is greater than the predetermined temperature value. The extinguishing agent flows from the tank to the emitter, where it is discharged.
