  • Patent number: 8091711
    Abstract: A dynamically real-time adaptive trommel screen system is revealed. The dynamically adaptive trommel screen system includes a fixture, a trommel screen disposed on the fixture for screening a mixture into regenerated filter granules and screened residues, a structured duct for transporting the regenerated filter granules and an enclosure for collecting the screened residues, a tilt control member arranged on the fixture for adjusting the tilt angle of the trommel screen, and a feedback controller that controls the tilt control member according to the mass flow rate of the screened residues when the trommel screen operates so as to adjust the tilt angle of the trommel screen instantly and dynamically. By the feedback controller and the tilt control member, the tilt angle of the trommel screen is adjusted in a real-time and dynamic way so as to increase the screening efficiency.

  • Patent number: 7485914
    Abstract: An interdigitized capacitor comprising first and second electrodes. The first electrode comprises two combs symmetrical to a first mirror plane. The fingers of the combs extend toward the first mirror plane. The second electrode comprises two combs and a linear plate. The combs are symmetrical to a second mirror plane and the fingers thereof extend toward the second mirror plane. The linear plate is located at the second mirror plane and connected to one finger of the combs of the second electrode. The first and second mirror planes are orthogonal. The fingers of the combs of the first and second electrodes are interdigitized.

  • Patent number: 7450790
    Abstract: A non-electronic all-dielectric (NEAD) or non-electronic RF (NERF) front-end that exploits isolation features of photonics to eliminate metal electrodes, interconnects and the antenna. An electro-optic (EO) modulator is integrated with a dielectric resonance antenna to exploit unique isolation features of photonics. A doubly (RF and optical) resonant device design maximizes the receiver sensitivity. High-Q optical disk resonators and dielectric resonant antennas are integrated to create an efficient mixing of light and RF fields. The resulting non-electronic RF technology produces an all-dielectric RF front-end which provides complete isolation between the air interface and the ensuing electronic circuitry, enabling the creation of an RF receiver that is immune to high-power electro-magnetic pulses (EMP) and High Power Microwave (HPM) pulses. The device can also be configured as a non-intrusive field probe that co-exists with a conventional receiver and detects a EMP or HPM attack.
