摘要： Methods and systems for stimulating and monitoring electrogenic cells are described. Some systems for stimulating electrogenic cells are based on the injection of electric currents into the cells via electrodes connected to the cells. Such stimulators may comprise an impedance element having an input terminal and an output terminal coupled to an electrode, and a voltage follower coupled between the input terminal and the output terminal of the impedance element, the voltage follower being configured to maintain a substantially constant voltage between the input terminal and the output terminal of the impedance element. The impedance element may comprise one or more switched capacitors at least in some embodiments. In some embodiments, the voltage follower may be implemented using a source follower.

摘要： A ceramic member unit includes at least insertion members and a ceramic member having insertion sections into which the insertion members are inserted respectively. Each of the insertion sections has at least an insertion opening which opens on a deeper side of an introduction opening in the surface of the ceramic member while communicating with the introduction opening and into which the insertion member can be inserted. The insertion section further has taper hole portions becoming narrower toward the insertion opening in a communication region between the introduction opening and the insertion opening. The taper hole portions are connected to the insertion opening while increasing in a taper angle toward the insertion opening.

摘要： A bubble detection sensor includes an emitter having an emitting surface and a receiver positioned on a side of a fluid conduit opposite the emitter. The receiver has a receiving surface adapted to receive a signal emitted by the emitter through a fluid of the fluid conduit. A sensor axis extending normal to the emitting surface and the receiving surface is disposed at a rotation offset angle with respect to a plane extending normal to a longitudinal conduit axis of the fluid conduit. The rotation offset angle is set to optimize a ratio of a sensitivity of the signal received by the receiver to an efficiency of the signal received by the receiver.

摘要： A nucleic acid detection device includes a microfluidic opening and a sensor stack. The sensor stack includes an electrochemical electrode and a photodetector. The electrochemical electrode is formed of a conductive material that is transparent to a fluorescent emission, the electrochemical electrode including a first side and an opposite second side, wherein the first side is exposed to the microfluidic opening. The photodetector is positioned relative to the second side of the electrochemical electrode to optically receive the fluorescent emission when passed through the electrochemical electrode.

摘要： A system for identifying a drug simulant includes an electronic sensing system structured to measure the value of an inherent property of the drug simulant; a processing unit in electrical communication with the electronic sensing system; and a memory unit in communication with the processing unit, the memory unit having a look-up table including a range of values of the inherent property of a given fluid and corresponding names of simulated drugs associated with each value. The processor is structured to identify a name of the simulated drug corresponding to the drug simulant by receiving signals indicative of the value of the measured inherent property from the sensing system and comparing the value to the look-up table in the memory.

摘要： A method of identifying the phase composition and/or changes in the phase composition of a fluid flowing through a turbomachine includes monitoring changes in at least one electrical parameter associated with operation of the turbomachine, and employing a known correlation between phase composition and or phase composition changes, and changes in the electrical parameter(s) to associate the monitored changes with changes in the actual phase composition of the fluid.
