  • Publication number: 20230090007
    Abstract: Various apparatus, systems, and methods for measuring a solution characteristic of a sample comprising microorganisms are disclosed. In one embodiment, a sensor apparatus is disclosed comprising a sample container comprising a sample chamber configured to receive the sample and a reference sensor component comprising a reference conduit having a reference conduit cavity defined therein. The reference conduit cavity can be at least partially filled with a reference buffer gel, buffer solution, or wicking component. A segment of the reference conduit can extend into the sample chamber. A reference electrode material can be positioned at a proximal end of the wicking component or extend partially into the reference conduit cavity. The sensor apparatus can also comprise an active sensor component having an active electrode in fluid contact with the sample. The sample in the sample chamber can be aerated through an aeration port defined along a surface of the sample container.

  • Publication number: 20210262003
    Abstract: Various methods, devices, and systems for determining the susceptibility of infectious agents to anti-infectives are disclosed herein. A method comprises introducing an inoculum solution comprising the infectious agent into a sample receiving space of a diagnostic device. The sample receiving space comprises a plurality of growth control wells devoid of the anti-infective and a plurality of active electrode wells comprising the anti-infective at differing concentrations. A water immiscible liquid can be introduced into the sample receiving space to seal the plurality of wells and the diagnostic device can be incubated for a period of time. The minimum inhibitory concentration (MIC) of the anti-infective on the infectious agent can be determined by monitoring and comparing one or more solution characteristics of the inoculum solution within the active electrode wells with the one or more solution characteristics of the inoculum solution with the growth control wells.

  • Patent number: 9270373
    Abstract: A data transport system for transporting data and auxiliary signals over an optical link comprises a transmitter, a receiver and an optical link. The transmitter and receiver are coupled to a first end of the optical link. The optical link includes a number of optical channels. A controller is coupled to the transmitter and the receiver, and controls the transmitter and the receiver to operate in a first state when data are detected at an input of the transmitter. Data are transported via the data transport system in the first state. The controller controls the transmitter and the receiver to operate in a second state when the data are detected as absent at the input of the transmitter. Data are prevented from being transported via the data transport system in the second state.
