Abstract: A system includes a bacteria culture array that includes a plurality of chambers each configured to receive a portion of a sample that includes bacteria. Each individual chamber of the plurality of chambers includes a chamber opening configured to permit access of the portion of the sample to the individual chamber. The system also includes one or more sensors configured to collect data from the individual chamber. The sensors are configured to contact the sample. Additionally, the system includes a monitoring and analysis system that includes a processor configured to receive the data from the one or more sensors at a first time and a second time, compare the data received at the second time to the data received at the first time, and identify a portion of the plurality of chambers of the bacteria culture array based on the comparing.

Abstract: A sensor assembly includes an impedance sensor element, an impedance sensor reader and a communications module. The communications module is configured to communicate with a remote computing device. The impedance sensor reader is coupled to the impedance sensor element. The impedance sensor reader includes a synthesizer and a detector. The synthesizer is configured to output an excitation signal having known values for a plurality of signal characteristics to the impedance sensor element and to generate the excitation signal based on a plurality of direct digital synthesizer (DDS) coefficients received from the remote computing device through the communications module. The detector is coupled to the impedance sensor element and configured to detect a response of the impedance sensor element to the excitation signal and determine an impedance of the impedance sensor element based at least in part on the response of the impedance sensor element to the excitation signal.

Abstract: A filtering unit is presented. The filtering unit includes at least two operational amplifiers, where each of the at least two operational amplifiers includes an input end and an output end, where the input end of one operational amplifier is coupled across the corresponding input end of another operational amplifier of the at least two operational amplifiers. The filtering unit also includes a direct current link operatively coupled to the at least two operational amplifiers and at least one thermoelectric module, where each thermoelectric module includes a conducting layer, where the direct current link and at least one of the at least two operational amplifiers are operatively coupled to the at least one thermoelectric module. A filtering system is also presented.
