摘要:
A contaminated aqueous composition is withdrawn from a groundwater extraction well and the groundwater is treated in a pump and treat system to remove a contaminant. The treating of the aqueous composition is monitored from a location remote from the groundwater extraction well and the treating is adjusted to remove a contaminant in accordance with the monitoring. A system to treat a contaminated aqueous composition comprises a capture zone to intercept a contaminated aqueous composition and a surface pump and treat system to receive and treat the contaminated aqueous composition from the capture zone. The system also includes a sensor that senses a contaminant in the contaminated aqueous composition and a monitor to receive information concerning the contaminant from the sensor and to consequently control the pump and treat system to treat the contaminated aqueous composition. The monitor is situated at a location remote from the pump and treat system.

A sampling device can monitor contaminants in groundwater. The sampling device comprises a semi-permeable membrane for contact with groundwater, in which the semi-permeable membrane is permeable to contaminants and impermeable to groundwater; an inner chamber formed by the semi-permeable membrane for containing the contaminants from the groundwater that diffuse through the semi-permeable membrane; and a sensor device communicating with the inner chamber. The sensor device is in contact with the contaminants contained within the inner chamber for monitoring the contaminants.

In a method for treating a contaminated fluid stream, a characteristic of a flow of the composition to a carbon adsorption zone is sensed. The sensing is remotely monitored to determine a treatment for the contaminated fluid stream. The contaminated fluid stream is then treated according to the monitoring. A system for treating a contaminated fluid stream comprises a sensor that senses a characteristic of a flow of a contaminated fluid stream prior to treatment and a monitor to receive information concerning the characteristic from the sensor and to consequently control the carbon adsorption zone to treat the contaminated fluid stream. The monitor is situated at a location remote from the carbon adsorption zone.
摘要:
An improved method and apparatus for monitoring the concentration of contaminants, including volatile organic compounds, in groundwater is provided comprising a semipermeable membrane defining an inner chamber. The chamber is carried within a mesh protective sleeve of cover to prevent abrasion or puncture of the chamber. The membrane is permeable to contaminants but impermeable to a reference fluid, which is distilled water. The method of sampling comprises placing the semipermeable membrane chamber, which contains the reference fluid, in contact with contaminated groundwater, thereby allowing contaminants to diffuse through the semipermeable membrane.

A method for reducing emissions from a plurality of moving assets includes receiving trip pattern data corresponding to positions and times from the moving assets and the preference data from a plurality of users. A database of trips made by the moving assets is then generated based on the trip pattern data and trip consolidation opportunities for the moving assets are identified based on the generated database. The method also includes ranking the trip consolidation opportunities based on the preference data and utilizing the ranked trip consolidation opportunities to provide shipping recommendations designed to reduce fuel consumption of the moving assets.

A mileage estimation system comprising a data collection module, a route determination module, a learning module, and a mileage calculation module is provided. The data collection module receives data corresponding to a position and time of a moving asset from a remote location and the route determination module obtains information from a map database for determining a plurality of routes between at least two location of the moving asset. The learning module in the system determines a route travelled by the moving asset from the plurality of routes based on mileage estimation criterion, and the mileage calculation module estimates the distance travelled by the moving asset based on the route travelled by the moving asset.

摘要:
An inventory management system automatically monitors inventory amounts, provides information concerning inventory, and decides if an order for replacement inventory should be placed. The system includes a storage for inventory, an indicator for monitoring and reporting the level of current inventory, and a controller for receiving information from different inventory suppliers and for integrating such information with information on current inventory amounts and estimated future use to decide if an order for replacing inventory should be made. An order is placed automatically to a supplier and the progress for the delivery of replacement inventory is automatically monitored. A method using this system for managing inventory includes the steps of automatic gathering information about the current inventory and deciding whether and when replacement inventory should be ordered.
