Sarah MARKI 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).

  • Method of device for testing a capacitively operating measuring device, which is designed for the detection of phase boundaries, and correspondingly equipped laboratory apparatus
    Patent number: 9074919
    Abstract: A device has at least one channel for detecting the phase boundary between media in a liquid container and has a probe which can be fed in the direction of the phase boundary and a circuit which processes a signal of the probe to detect a capacitance change. The device includes a testing module which executes an infeed movement of the probe. The testing module performs an analysis of the signal of the channel, and makes a connection statement about the electrical connection between the probe and the measuring circuit. The testing of the electrical connections is performed in a dry manner, i.e., a phase boundary does not have to be searched for or penetrated for the testing.
