  • Portable air purification system
    Patent number: 11974888
    Abstract: A system, method, and air purification device. Air is taken in from an environment into the air purification system. The air is filtered with a primary filter. The filtered air is treated with vacuum ultraviolet radiation in a primary reaction chamber to generate irradiated air. The irradiated air is treated with ultraviolet-C radiation in a secondary reaction chamber to remove ozone and neutralize contaminants to generate purified air. The purified air is emitted back into the environment from the air purification system.

  • System and method for converting AC power to DC power using sensorless field oriented control
    Patent number: 8659923
    Abstract: High voltage DC power, which is produced by rectifying AC power generated by an AC generator, is controlled and regulated without the need for measuring the position of the rotor with hardware. A Field oriented controller uses a sliding mode observer to estimate the position of the rotor without the use of position detection hardware. The estimated position of the rotor and the AC current are then used by the field oriented controller algorithm to regulate a DC output from a rectifier driven by an AC generator.
