Abstract: A stormwater treatment system for separating contaminants from flowing stormwater is provided. The stormwater treatment system includes a tank including an inlet for receiving stormwater runoff and an outlet for outputting stormwater subsequent to treatment. The tank includes a storage chamber for collecting pollutant. A sensor is provided within the tank and arranged and configured to generate a pollutant level indicative signal. A control system is in communication with the sensor. The control system is operable, based upon the pollutant level indicative signal, to identify when pollutant build-up within the storage chamber reaches a level requiring service and to responsively output a service notification.

Abstract: Compositions for providing controlled-release of an active material comprise a dispersant and microcapsules containing the active material. The compositions contain the dispersant and/or microcapsules at relatively low levels to avoid negatively impacting the surfaces treated with the compositions. The active material is preferably a perfume and the composition provides a controlled-release scent, along with controlling malodor when the compositions fuirther comprise optional odor control agent. Methods of providing a controlled-release of an active material on a surface comprise the step of contacting the surface with a composition comprising a dispersant and microcapsules containing an active material.

Abstract: A stormwater runoff detention system includes a system including an inlet, a first surge chamber, a second surge chamber and one or more storage chambers.

The first surge chamber includes a discharge outlet and an overflow outlet to the storage chamber. The second surge chamber is connected to receive stormwater from the inlet primarily after the first surge chamber has begun overflowing to the storage chamber. The second surge chamber includes a discharge outlet and an overflow outlet to the storage chamber or to a second storage chamber.

Abstract: The present invention provides a reverse auction system for procuring goods and services. A customer business provides details concerning its needs by means of a detailed questionnaire. An invitation to bid is then sent to potential sellers. The invention rates bidders according to quality and risk based on historical data of customer service. The bidding occurs over a specified number of rounds. Bidding is semi-blind, wherein bidders can view the bids, bid evaluations, and bid ranking for each preceding round, but not the current round. Bidding may be done manually or through an automate proxy system. Bidders are identified only by their respective quality and risk ratings. After each round, bidders are ranked according to a three-factor evaluation that combines bid price, quality rating, and risk rating and compares them to the supplied customer information.

Abstract: A method, program and system for conducting a reverse auction are provided by the present invention. The auction is divided into a specified number of rounds of specified duration, and bids are received from a plurality of bidders. The bidders are rated according to specified qualitative parameters. While the auction is open the bidders are anonymous to each other and are identified only by their respective qualitative ratings. Bidders may only view competing bids, and their own relative bid ranking, from previously closed rounds. The customer of the reverse auction has complete discretion in choosing the winner.

Abstract: A method, program and system for analyzing product price structures are provided by the present invention. The invention involves receiving product information about a multi-component product, such as a service plan, and analyzing individual price elements within the multi-component product. These individual price elements may include, purchase price, fixed periodic charges, up-front charges, variable charges, discounts, service contract length, service and maintenance costs, labor costs, and purchase minimums. The invention then determines customer requirements and calculates the total cost over an estimate service life of the product according to these requirements. This projected total cost is then converted to a single figure of merit that reduces the price structure of the product to a single financial figure that can be compared across products with different price structures.

Abstract: The present invention provides a method, program and system for automated proxy bidding in an auction. The invention includes defining a desired price position relative to competing bids based on qualitative ratings associated with competing bidders and submitting a bid related to a product. Competing bids are retrieved along with the qualitative ratings associated with each competing bidder, and a determination is made as to whether the submitted bid achieves the desired price position relative to the competing bids. If the submitted bid does not achieve the desired price position relative to the competing bids, the bid is adjusted according to a predefined sequence of price moves. The desired price position might have a specified premium relative to competing bidders with lower qualitative ratings and a specified discount relative to competing bidders with comparable and higher qualitative ratings.

Abstract: A system and related method for separating floating and nonfloating particulate and entrained, suspended, and/or dissolved contaminants from a fluid. The system includes a tank with a lower chamber spaced from an outlet or upper chamber by a confinement deck. The deck includes one or more sockets for receiving one or more filter units for fluid treatment. In addition, the lower chamber of the tank acts as a pretreatment sump to remove floating and nonfloating particulates, thereby reducing the load on the filter units. The filter units are configured for radial and/or upward flow of the fluid from the lower chamber. The filter units may include one or more filter media through which the fluid pass prior to exiting the tank. The filter units include a removable screening retainer for retaining the filter media and/or to screen relatively large contaminants. The filter unit may be removed for ease of tank maintenance and replacement of filter media.

Abstract: A fluid separation system includes a tank with a storage chamber for retaining floating and non-floating particulates. The tank includes a baffle for retaining floating particulates within the storage chamber and for directing flow out of the storage chamber. The tank also includes a bypass with an inlet flow control zone and an outlet flow control zone. The flow control zones are separated by a weir sized and positioned to regulate the fluid flow through a baffle port into the storage chamber. The weir also provides control of the flow rate at which incoming fluid is diverted directly through the bypass to the tank outlet rather than into the storage chamber. The baffle and/or the weir may be curved, and the baffle may include a complex curve, to aid in the smoothing of the fluid flow within the storage chamber to improve particulate separation.

Abstract: A screen apparatus for improved separation of particulates from a fluid stream. The screen is configured and arranged to filter relatively large particulates from the fluid stream as the fluid stream passes from a storage chamber of the tank to a tank outlet. The screen is removably affixed to a diverter, such as a baffle, used to divert a portion or all of the fluid into the storage chamber. The screen is preferably shaped to substantially conform to the shape of the diverter to aid in the smoothing of the fluid flow within the retention section of the tank. The screen may be entirely porous, or it may be non-porous at its leading edge to minimize particulate build-up at the transition from the tank interior wall to the screen. The apparatus may optionally include a second screen to provide additional filtering of floating particulates as the fluid level in the tank exceeds the crown elevation of the inlet.

Abstract: Compositions for providing controlled-release of an active material comprise a dispersant and microcapsules containing the active material and a stabilizer. The compositions contain the dispersant and/or microcapsules at relatively low levels to avoid negatively impacting the surfaces treated with the compositions. The active material is preferably a perfume and the composition provides a controlled-release scent, along with controlling malodor when the compositions further comprise optional odor control agent. The stabilizer improves the stability of the microcapsule. Methods of providing a controlled-release of an active material on a surface comprise the step of contacting the surface with a composition comprising a dispersant and microcapsules containing an active material and a stabilizer.

Abstract: The systems and methods described herein include systems and methods for serving data including streams of content, such as video content, audio content, and other types of content, and for serving the data at a selected level of service. The server provides a flexible platform that can examine an incoming request for content and based on certain attributes associated with that request, make a determination of the level of service that the request is to receive and a determination of whether the system currently has the capacity to handle the request at that level of service. Additionally and optionally, the server allows a network service provider/administrator to determine which attributes are relevant in determining the proper level of service and what level of service, or characteristics of that level of service will be associated with the attribute.
