Patents by Inventor Holger Bartos

Holger Bartos 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).

  • Publication number: 20040241051
    Abstract: The present invention relates to devices for efficient transport, transfer and movement of fluids. In particular, the invention provides fluidic micro-structures for controlled transport and movement of liquids in devices for analytical and other purposes. Devices of the invention include one or more features that can enhance performance of the fluid transfer, referred to as a pre-shooter stop, a butterfly structure, a cascade structure, a waste chamber inlet, a capillary driven sample inlet chamber, a capillary stop structure, a bifurcation flow-through structure, and a hydrophobic vent.

  • Publication number: 20040206408
    Abstract: The invention relates to a microfluidic switch for stopping a liquid flow during a time interval with the following features: the switch has at least one first channel and at least one second channel; the first channel and the second channel have a common end area; the first channel in the end area has a stopping mechanism for stopping of a liquid flow flowing in the first channel; the stopping mechanism can be controlled by means of a liquid flow flowing in the second channel for continuing the liquid flow in the first channel. Transport in the first and the second channel takes place advantageously by the capillarity acting in the channel.

  • Publication number: 20030166265
    Abstract: A micro-liter liquid sample, particularly a biological sample, is analyzed in a device employing centrifugal and capillary forces. The sample is moved through one or more sample wells arrayed within a small flat chip via interconnecting capillary passageways. The passageways may be either hydrophobic or hydrophilic and may include hydrophobic or hydrophilic capillary stops.
