Patents by Inventor Robert Laemmle

Robert Laemmle has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Hybrid cooler/dryer and method therefor
    Patent number: 11067483
    Abstract: A hybrid cooler/dryer that conditions a sample gas includes a heat exchanger, a condensate-removal device, and a membrane dryer. In some embodiments, the hybrid cooler/dryer also includes passive cooling, as embodied by an air amplifier and heat sink, or a length of tubing that exposes the sample gas to ambient temperature. The hybrid cooler/dryer requires no electrical power.
    Type: Grant
    Filed: March 29, 2019
    Date of Patent: July 20, 2021
    Assignee: Perma Pure LLC
    Inventors: Craig Sunada, Cui Jun, Yuan Lin, Robert Laemmle

  • Band agile filter
    Patent number: 7327210
    Abstract: A microwave filter and method for remotely tuning a microwave filter from one sub-band to another sub-band using metallic rings to adjust the capacitance or inductance of the resonator. In adjusting the capacitance, a plurality of metallic rings are disposed in the upper section or end of the resonator. Each ring has an RF switch that connects or disconnects each ring to ground, thereby varying the capacitance of the resonator. In adjusting the inductance, a plurality of metallic rings are disposed perpendicular to the magnetic field of the resonator. Each ring has an RF switch disposed within the electrical path of the ring that opens or closes the electrical path of each ring. By opening and closing each ring, the magnetic field of the resonator is altered, thereby varying the inductance of the resonator.
