Angel Rivero Jimenez 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).

  • Wide range, very high resolution differential mobility analyzer (DMA)
    Patent number: 7723677
    Abstract: The present invention consists of a differential mobility analyzer (DMA) intended for achieving the electric field conditions necessary so that it has an component opposite to the drag flow. This electric field component opposite to the drag flow causes the main electric field to be not perpendicular to the velocity field of the drag flow but oblique. Under these conditions, it is possible to increase the resolution of the device, thus reducing the threshold of errors in the detection of the type particle injected in the analyzer. This invention is characterized by the arrangement and nature of the electrodes intended for obtaining the oblique electric field. The invention also comprises the use of this analyzer as part of a device which comprises it, giving rise to an assembly combining the efficiency of the analyzer of the state of the art with the high resolution of the analyzer of the invention.

  • Wide range, very high resolution differential mobility analyzer (DMA)
    Patent number: 7521673
    Abstract: The resolution of a differential mobility analyzer (DMA) and the range of valid mobility values for the charged particles that it can detect are increased. The DMA makes use of a flat configuration and a purely two-dimensional operating model in which shims are used for improved adjustment and precision of the parallel faces that make up the analysis area. The analyzer uses a closed and pressurized aerodynamic tunnel to establish a cross flow with a very high Reynolds number.
