System and method including analytical units
First Claim
1. A sensor system comprising:
- a processor;
a sensing circuit comprising a mandrel, wherein the sensing circuit is configured to generate a first signal and a second signal, each of the first signal and the second signal relating to at least one of resistance, capacitance, and inductance of the mandrel, andwherein the processor is coupled to the mandrel,wherein the processor is configured to compare the first signal to a first stored reference value to determine contact of a mandrel extension element with a liquid, andwherein the processor is configured to compare the second signal to a second stored reference value to determine a presence of an extension element on the mandrel, a fill level of an extension element, or a proximity of the mandrel to a conductive target,wherein the sensing circuit includes a phase-locked loop circuit and a tank circuit associated with the phase-locked loop circuit, the phase-locked loop circuit incorporating the mandrel and a set of varactors forming a tank block of the tank circuit, the set of varactors coupled to the processor.

Abstract
Systems and methods for processing and analyzing samples are disclosed. The system may process samples, such as biological fluids, using assay cartridges which can be processed at different processing locations. In some cases, the system can be used for PCR processing. The different processing locations may include a preparation location where samples can be prepared and an analysis location where samples can be analyzed. To assist with the preparation of samples, the system may also include a number of processing stations which may include processing lanes. During the analysis of samples, in some cases, thermal cycler modules and an appropriate optical detection system can be used to detect the presence or absence of certain nucleic acid sequences in the samples. The system can be used to accurately and rapidly process samples.
