The controller includes a plurality of input-output (IO) ports each configured to couple to the one or more sensors. Moreover, each of the IO ports is configured to couple to a plurality of sensor types such that each IO port is configured to couple more than one sensor type. The controller also includes an interface configured to receive a selection of a selected mode from a plurality of modes each corresponding to a sensor type. Furthermore, the controller includes a switch block having a plurality of switches each configured to toggle a connection in the switch block according to the selected mode.

摘要： 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.

摘要： 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.

摘要： The present approach relates to avoiding azimuthal blur in a computed tomography context, such as in dual energy imaging with fast kV switching. In accordance with certain aspects, the focal spot position is held stationary in the patient coordinate system within each respective view and the detector signals within the view are summed. In one embodiment, this results in the low and high energy views within the signal being collected from the same position within the patient coordinate system.

摘要： The present approach relates to the use of energy-resolved, photon-counting detectors, such as CZT- or CdTe-based detectors, to acquire spectral information that is not available with conventional energy-integrating detectors. In certain embodiments, the present approach discussed reduces or eliminates spectral contamination incurred by transient signals in neighboring pixels in designs employing coincidence logic and shaping amplifiers with short shaping times.
