Abstract: The invention is a biological process for purifying waste water in order to produce an effluent with a low content of carbon and of oxygenated nitrogen compounds. The process includes an initial step of mixing the waste water in a biological reactor with activated sludge to denitrify the resulting mixture. Then, air is introduced into the mixture to form an anoxic sludge thereby directly oxidizing carbon present in the anoxic sludge and removing carbon therefrom, simultaneous with the denitrification. The anoxic sludge is clarified to separate it from a denitrified intermediate effluent. The clarified anoxic sludge is recycled to the biological reactor. Then, intermediate effluent is nitrified to form a nitrified liquor and a portion of the nitrified liquor is recycled into the anoxic sludge that is present in the biological reactor, thereby subjecting the anoxic sludge to oxygen present in nitrified compounds and consequently further removing carbon from the anoxic sludge, simultaneous with the denitrification. The rate of removal of carbon is controlled as a function of the flow rate/pollution characteristics of the anoxic sludge while a redox potential of the anoxic sludge is continuously measured. A nitrate concentration of the intermediate effluent is continuously measured. There is an adjustment of an amount of air introduced into the anoxic sludge in accordance with the measured redox potential and measured nitrate concentration. A recycling flow rate of the nitrified liquor is adjusted in accordance with the measured redox potential and measured nitrate concentration. The remaining nitrified liquor is the final effluent.

Title: Optical add/drop multiplexer/demultiplexer
Inventor: HARLEY JAMES ST LEGER
IPC: H04Q11/00
Filed: 1999-05-11
Abstract: An add/drop multiplexer/demultiplexer (ADM) for switching, modulating and attenuating optical signals in a fiber optic network employing WDM. The ADM has an optical multiplexer for splitting an input WDM signal into individual optical signals, leading to respective 2x2 switches. Each switch has another input originating from a plurality of "add lines". The input signals are tapped, optoelectronically converted and fed to a controller, which reads switching, modulation and attenuation instructions. The instructions can be encoded into a low-frequency dither signal that is embedded within the input optical signals. The ADM can accordingly be instructed to reroute traffic, dynamically equalize optical channel power levels, and add or remove dither, all in real time. A bidirectional ADM can be constructed from two unidirectional ADMs. Also, a single, general multi-input multi-output switch can be used to provide an arbitrary mapping between individual input and output optical signals.

Title: Method and apparatus for providing failure detection and recovery with predetermined degree of replication for distributed applications in a network
Inventor: CHUNG PI-YU
IPC: G06F11/16
Filed: 1999-06-03
Abstract: An application module (A) running on a host computer in a computer network is failure-protected with one or more backup copies that are operative on other host computers in the network. In order to effect fault protection, the application module registers itself with a ReplicaManager daemon process (112) by sending a registration message, which message, in addition to identifying the registering application module and the host computer on which it is running, includes the particular replication strategy (cold backup, warm backup, or hot backup) and the degree of replication associated with that application module. The backup copies are then maintained in a fail-over state according to the registered replication strategy. A WatchDog daemon (113), running on the same host computer as the registered application periodically monitors the registered application to detect failures. When a failure, such as a crash or hangup of the application module, is detected, the failure is reported to the ReplicaManager, which effects the requested fail-over actions. An additional backup copy is then made operative in accordance with the registered replication style and the registered degree of replication. A     SuperWatchDog daemon process (115-1), running on the same host computer as the ReplicaManager, monitors each host computer in the computer network. When a host failure is detected, each application module running on that host computer is individually failure-protected in accordance with its registered replication style and degree of replication.

Inventor: HUNT TREVOR
IPC: B62D25/12
Filed: 1997-12-10
Abstract: A hood latch assembly (10) has a housing (14) having a mouth (13). A ratchet (16) is pivotally mounted within the housing (14) to cooperate with the mouth (13) to pivot between an open, a secondary closed and a primary closed condition for receiving, engaging and cinching a keeper of a striker (80). The ratchet (16) is biased to the open condition. A pivotally mounted primary pawl (18) is biased for engagement with the ratchet (16) to releasably retain the ratchet (16) in the primary closed condition. A pivotally mounted secondary pawl (62) is biased for engagement with the ratchet (16) to releasably retain the ratchet (16) in the secondary closed condition. The secondary pawl (62) has a release lever (20) which rotates between a deployed position and a retracted position. As the ratchet (16) engages the striker (80), the ratchet (16) will rotate in a latching sense from the open condition to the secondary closed condition. As the ratchet (16) further rotates from the secondary closed to the primary closed condition, fully engaging the striker (80), the secondary pawl (62) follows the ratchet (16), allowing the release lever (20) to rotate from a deployed position to a retracted position. Upon release of the primary engagement by disengaging the primary pawl (18), the ratchet (16) will rotate from the primary closed to he secondary closed condition. The secondary pawl (62) will follow the ratchet (16) rotating the release lever (20) from the retracted position to the deployed position. The operator then manipulates the release lever (20) to release the ratchet (16), allowing the ratchet (16) to rotate from the secondary closed to the open condition. The hood latch (10) has a light (82) which is operable responsive to movement of the release arm (20) moving from the retracted position and the deployed position.      Changes of the hood latch (10) between the primary closed condition and the secondary closed condition will open and close the switch (78).      The switch (78) is disposed between a light source (82) mounted to illuminate the hood latch (10) region and a source of electrical power.  Opening and closing of the switch (78) will responsively illuminate the light (82).
