Abstract: A method and system of controlling addition of a treating agent based on a control function comprising a plurality of demand values is disclosed. Process parameters of a fluid to be treated are measured and one or more control signals are generated based on the measured process values and the control function. The control signals are used to actuate a treating agent dosing system and also used to monitor and compare the levels, status or condition of the treating agent. Additional features of the invention compensate for rain events.

Abstract: A method and apparatus for treating wastewater streams by adding, either separately or as a mixture, a nitrate containing compound and an alkaline material in an amount sufficient to achieve a lower concentration of atmospheric hydrogen sulfide and dissolved sulfides downstream of the addition as compared to the atmospheric hydrogen sulfide and dissolved sulfides present in the wastewater stream prior to the addition. By adding alkaline material in addition to a nitrate containing compounds, the amount of nitrate containing compound added can be reduced by at least 10% as compared to the amount of nitrate that would theoretically need to be added in the absence of alkaline material to achieve a comparable lower concentration of atmospheric hydrogen sulfide and dissolved sulfides in the wastewater stream.

Abstract: Systems and methods for reducing odors utilizes oxidation-reduction potential to characterize the quality of water or wastewater and control addition of a species thereto that reduces or inhibits biological sulfide generation. Oxidation-reduction potential is measured at a downstream station and, based on the measurement, a nitrate compound is added at an upstream station to promote inoffensive biological products instead of foul-smelling products.

Abstract: A system and method for tax reporting of taxable and non-taxable distributions, gains and losses of investments including providing access to tax information regarding the investments and providing various functions pertaining to the tax information is provided. The system and method can be used by, among others, financial institution personnel to view and adjust tax information on tax forms, such as the United States Internal Revenue Service (IRS) 1099, 1042S and 480.6A,B,C forms. The system and method can be used to perform tax reporting for any number of kinds of tax information and investment information, including tax information associated with investments in any kind of banking or trust account such as checking, savings, lines of credit, home equity loans, mortgages, trust accounts, and certificate of deposit, creditor accounts such as credit card accounts and loans, and employment-related accounts such as employer loans and employee stock purchase plans.

Abstract: In a switch fabric environment, which includes a buffer, packet data of different class-types from different sources is received, stored in the buffer, processed and outputted to its intended destination. As the buffer fills up, transmission from some of the data sources is stopped to avoid dropping of packets. To avoid packet loss, when the occupancy of the buffer reaches a first threshold value, further transmission of a first-class type of data is precluded from the particular source of that data then being received, while transmission from other sources of that same first-class type of data is not precluded from these other data sources until first-class type of data from such other sources is also received. Further, data of a second-class type is not precluded from being transmitted as long as the amount of data stored in the buffer remains below a second threshold, which is greater than the first threshold.

Abstract: The current mode bus driver which is disclosed couples input digital signals to a bus which is normally biased with a voltage difference representing one binary type. The current mode bus driver responds to input digital signals of the other binary type by connecting a current source to one lead of the bus and a current sink to the other lead of the bus, thereby driving the bus to a voltage difference which represents the other binary type. In response to input digital signals of the first-mentioned binary type, the bus driver isolates the current source and current sink from the bus and connects the current source directly to the current sink. The selective switching is performed by n-channel MOSFETs which are driven by the input digital signals through unique buffer driver circuits employing a CMOS inverter, an n-channel MOSFET and an NPN transistor. A combination of MOSFETs and NPN transistors provide a current source and sink that permit operation of the bus at very low voltage levels.

Abstract: A differential voltage bus system is disclosed wherein the two leads of the bus are biased by the termination networks with a predetermined voltage difference representing a digital signal of one binary type. The bus driver in each bus master connects a current source to one of the two bus leads and a current sink to the other of the two bus leads in response to an input digital signal of the other binary type thereby changing the voltage difference on the bus to represent the other binary type. In response to an input digital signal of the first-mentioned binary type, the bus driver isolates the current source and sink from the bus and connects them together in order to decrease the detrimental effect of transients. The selective switching in the bus driver is performed by MOSFET switches which are driven by buffer driver circuits each of which uses a combination of MOSFETs and an NPN transistor to drive its respective MOSFET switch with a high peak current thereby enabling rapid switching.
