摘要： A microbial sensor, system, and method that can be used to determine a chemical environment and/or substrate concentrations in anaerobic or aerobic environments, such as soils, sediments and ground waters, are disclosed. An exemplary system uses one or more (e.g., inert) measurement electrodes and a reference electrode. The reference electrode can include an electrode exposed to atmospheric oxygen (e.g., a cathode) or an electrode exposed to stable anaerobic or aerobic conditions. The exemplary microbial sensor system measures open-circuit voltage to characterize the chemical (oxidizing or reducing) environment and/or recovery voltage to measure substrate concentrations in the subsurface.

摘要： A microbial sensor, microbial sensing system, and method that can be used to determine the chemical environment of unsaturated soils, rhizosphere, and/or plants are disclosed. The microbial sensing system can be used for monitoring the health of plants including nutrients, salinity, contaminants, chemicals (pesticides, herbicides) and diseases. A microbial sensing system can include one or more indicator electrodes and a reference electrode. The microbial sensing system can include a signal acquisition and/or communication module to allow the real-time collection of data from field deployments and laboratory investigations.

摘要： Methods and systems for monitoring microbial activity and microbial communication in an environment are disclosed. Exemplary methods include measuring a high impedance voltage between a reference electrode and one or more measurement electrodes to monitor microbial activity. Microorganisms form a biofilm that attaches to at least one of the one or more inert measurement electrodes and that allows for measuring the microbial activity, characterizing the environment, and/or monitoring microbial communication in the environment.

摘要： A supply valve includes a housing with a bore and an outlet and a pair of inlets communicating with the bore. The valve also includes a shuttle slidable in the bore in response to a pressure differential between the inlets to communicate one of the inlets to the outlet and to close the other inlet when the pressure level at the one inlet is greater than the pressure level at the other inlet. The shuttle slides to close the one inlet and communicate the other inlet to the outlet when the pressure differential between the inlets reaches a predetermined level. The shuttle includes a pair of fluid pressure responsive areas corresponding to each of the inlets. At least one of the areas includes one portion communicated to its corresponding inlet and another portion communicated to the outlet when the corresponding inlet is closed, the other portion being communicated to the corresponding inlet when the corresponding inlet is communicated to the outlet. The improved valve also includes restricted orifices providing uninterrupted communication between the outlet and the other portion of the areas and passages communicating the outlet with each of the inlets when the other inlet is closed.
