Abstract: Various examples are provided examples related to resistive content addressable memory (RCAM) based in-memory computation architectures. In one example, a system includes a content addressable memory (CAM) including an array of cells having a memristor based crossbar and an interconnection switch matrix having a gateless memristor array, which is coupled to an output of the CAM. In another example, a method, includes comparing activated bit values stored a key register with corresponding bit values in a row of a CAM, setting a tag bit value to indicate that the activated bit values match the corresponding bit values, and writing masked key bit values to corresponding bit locations in the row of the CAM based on the tag bit value.

Abstract: Systems and methods include a computer-implemented method for determining a concentration of hydrocarbon fuel in a fluid sample. A thin Cyclic Olefin Copolymer (COC) film of a COC layer having a honeycomb mesh-pattern forming a conductive metal trace is sputtered. The thin COC film is configured to dissolve upon contact with alkyl aromatic compounds present in hydrocarbon fuels. A fluid sample of a hydrocarbon fuel is positioned in an open area on the thin COC film. A resistivity of the conductive metal trace is monitored. A determination is made in response to the monitoring that a change in resistivity of the conductive metal trace has occurred resulting from dissolution of the thin COC film. A time duration is measured from the positioning of the fluid sample to the resistivity change. A concentration of the hydrocarbon fuel in the fluid sample is determined based on the time duration.

Abstract: Hydrocarbon contaminant detection system using polymer film includes a sensor assembly, a syringe, a heater assembly and a controller. The sensor assembly includes a cyclic olefin copolymer (COC) film including electrically conductive materials, and can complete an electrical circuit. The COC film can dissolve in a presence of a hydrocarbon contaminant, breaking the electrical circuit. The syringe can carry a lubrication oil sample to be tested using the sensor assembly. The syringe is operable to contact the lubrication oil sample with the COC film of the sensor assembly. The heater assembly can heat the lubrication oil sample before the lubrication oil sample is loaded to the syringe. The controller can perform operations including operating the syringe to flow the heated lubrication oil sample onto the COC film of the sensor assembly at a pre-determined flowrate.
