Abstract
Disclosed are devices, systems and methods for assessing the integrity of electrical connections between elements of interfacing electronic devices. In some aspects, a system includes an analysis device having electronics that interface with an assay cartridge inserted into the analysis device, wherein the analysis device is configured to conduct a preflight test in which impedance values for each circuit between the assay cartridge and analysis device are rearranged and assessed to determine the electrical connection integrity of the assay cartridge to the analysis device prior to implementing the assay.
Claims20
A method for assessing the integrity of electrical connections between interfacing electronic devices the method comprising:
- establishing an electrical connection between a first electronic device and a second electronic device;
- measuring impedance values for one or more electrodes on the first electronic device;
- reordering the impedance values to create reordered impedance values;
- and
- determining a quality factor of the reordered impedance values, wherein if the quality factor is above a predetermined threshold, the first electronic device is electrically connected to the second electronic device.
A method for assessing the integrity of electrical connections between interfacing electronic devices the method comprising:
- establishing an electrical connection between a first electronic device and a second electronic device;
- measuring impedance values for one or more electrodes on the first electronic device;
- reordering the impedance values to create reordered impedance values;
- and
- determining a quality factor of the reordered impedance value, wherein if the quality factor is within a predetermined threshold range, the first electronic device is electrically connected to the second electronic device.
A method for assessing the integrity of electrical connections between interfacing electronic devices the method comprising:
- establishing an electrical connection between a first electronic device and a second electronic device;
- measuring impedance values for one or more electrodes on the first electronic device;
- ordering the impedance values to match at least one reference order wherein the reference order is based on prior impedance values obtained from a previous qualified run on the second electric device or impedance values derived from devices of the same type as the second electronic device;
- determining a command for operating or terminating a procedure using the first electronic device and second electronic device;
- and
- actuating the first electronic device, the second electronic device or both in accordance with the determined command.
