David W. Greve 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).

  • Patent number: 11113594
    Abstract: Materials, methods of making, and methods of using an integrated wireless detector for real time interrogating metallic tubular structures comprising: an RF patch antenna; a passive surface acoustic wave (SAW) sensor; and data analytic methodologies. An embodiment relates to interrogating a metallic structure having a uniform cross section using an antenna which launches electromagnetic radiation. A sensor may be located within the structure is configured to re-emit electromagnetic radiation modified depending on parameters for which the sensor has been functionalized. An antenna may receive radiation as modified by the sensor, or may receive the transmitted or backscattered radiation directly, without use of a sensor. The antenna then communicates wirelessly with an interrogator providing data which may be used to understand the operational status of the structure in real-time.

  • Patent number: 10155222
    Abstract: The disclosure describes a prism containing a microfluidic channel. By coupling bulk acoustic wave generators to opposing sides of the prism, a standing bulk acoustic wave field can be excited in the prism and in the microfluidic channel. Because the microfluidic channel is titled with respect to the nodes of the bulk acoustic wave field, the prism microfluidic channel device can be used to separate microparticles and biological cells by size, compressibility, density, shape, or mass distribution. This technology enables high throughput cell sorting for biotechnology applications such as cancer cell detection.
