    Abstract: A system and method for purifying an aqueous contaminated fluid from colloidal contaminants using a closed-loop feedback control system are disclosed. Contaminated fluid flows into a mixer and mixed with a purifying agent, such as diatomaceous earth, to facilitate metathesis reaction between the purifying agent and the contaminants. The purifying agent entraps the contaminants, and is subsequently removed in a separator into sediments. An estimation of the amount of the purifying agent to dispense is performed using pre-defined equations or look-up tables stored in the database, including relationship between the concentration of contaminants in the fluid and the concentration of the added purifying agent. An automated feedback control is applied to fine tune the purification process into compliance with regulations. High accuracy of measurements is ensured by selecting the same material for both the purifying agent and the trapping medium of analyzers, and additionally by the design of the analyzers.

    Abstract: A communications network has a plurality of nodes interconnected by an optical transmission medium. The transmission medium is capable of a carrying a plurality of wavelengths organized into bands. A filter at each node for drops a band associated therewith and passively forwards other bands through the transmission medium. A device is provided at each node for adding a band to the transmission medium. Communication can be established directly between a pair of nodes in the network sharing a common band without the active intervention of any intervening node. This allows the network to be protocol independent. Also, the low losses incurred by the passive filters permit relatively long path lengths without optical amplification.

    Abstract: A method and apparatus for adjusting power in an optical signal are disclosed and a bidirectional equalized amplifier for providing bidirectional equalization, employing the apparatus and method is disclosed. Use of the method and apparatus to form a seamless ring in an optical network is also disclosed. The method of adjusting power involves splitting an input composite signal into respective drop signals in separate wavelength bands and respective pass signals with a splitter. An attenuator attenuates the drop signals to produce attenuated drop signals. A combiner combines the attenuated drop signals to produce a first output composite signal in which the power is equalized.
