Title: Method and system for resynchronizing a phase-shifted received data stream with a master clock
Inventor: NOVAK PETER DAVID
IPC: G06F13/42
Filed: 1997-03-24
Abstract: A method and system in a data processing system for resynchronizing a received data stream (58) with a master clock (72) having a master clock frequency, wherein the received data stream (58) is clocked with a received data clock (56) that is out of phase with the master clock (72) by an arbitrary number of degrees. The master clock (72) and the received data clock (56) are compared (120, 204) at a frequency of a resynchronization clock for a predetermined number of times to produce comparison results (208). The resynchronization clock frequency may be less than the frequency of the master clock. The comparison results are analyzed to produce a relative phase indicator (134).  In response to the relative phase indicator exceeding, or being less than, a phase shift threshold (136, 210), the received data stream is reclocked (144) at a rising (212) or falling edge (214) of the master clock (72) to produce a resynchronized data stream (88), wherein the resynchronized data stream (88) is synchronized with the master clock (72) and contains the data of the received data stream (58).

Title: Surface modification of polymers and carbon-based materials
Inventor: TENNYSON RODERICK C
IPC: C08J7/054
Filed: 1996-06-21
Abstract: This invention provides an improved process for surface modification of polymers and carbon-based materials, and improved materials produced by the process. The preferred surface modification process of the present invention comprises three steps: a first activation step wherein reactive hydrogen groups are formed in a surface layer of a polymeric or carbon-based material;  a second silylation step wherein the reactive hydrogen groups are reacted with a silylating agent to form silicon-containing groups; and a third stabilization step wherein an upper portion of the activated, silylated layer is oxidatively converted to a silicon dioxide enriched surface layer. The process can be performed using materials not having pre-existing reactive hydrogen groups or precursor groups. Surface modified materials according to the present invention have improved properties, such as erosion resistance and oxygen and water barrier properties, and are potentially useful in numerous industries, such as aerospace and packaging.

Title: Methods and apparatus for providing universal readability of electronic mail attachments
Inventor: SOMMER JOSEPH M
IPC: H04L29/08
Filed: 1998-01-05
Abstract: Systems and methods for providing fully readable email and attachments where senders and receivers are connected by less than fully compatible email providers or have less than fully compatible software. For example, where a sender employs word processing or graphics software not employed by the intended recipient, a network service provider downloads a loaner or loaners to the recipient so that the recipient can fully read or utilize the email and attachments. Preferably, the loaner or loaners are destroyed once the email and attachments have received. Alternatively, rather than downloading a loaner, access to a web site may be provided to the recipient who can download a fully utilizable copy of the email and attachments by facsimile, for example. In either case, senders and receivers no longer need to have the same software programs to fully communicate utilizing email.

Title: Electrochemical fuel cell stack with improved reactant manifolding and sealing
Inventor: WOZNICZKA BOGUSLAV M
IPC: H01M8/24
Filed: 1998-07-16
Abstract: An electrochemical fuel cell stack with improved reactant manifolding and sealing includes a pair of separator plates interposed between adjacent membrane electrode assemblies. Passageways fluidly interconnecting the anodes to a fuel manifold and interconnecting the cathodes to an oxidant manifold are formed between adjoiningnon-active surfaces of the pairs of separator plates. The passageways extend through one or more ports penetrating the thickness of one of the plates thereby fluidly connecting the manifold to the opposite active surface of that plate, and the contacted electrode. The non-active surfaces of adjoining separator plates in a fuel cell stack cooperate to provide passageways for directing both reactants from respective stack fuel and oxidant supply manifolds to the appropriate electrodes. The fuel and oxidant reactant streams passageways are fluidly isolated from each other, although they both traverse adjoining non-active surfaces of the same pair of plates. The present manifolding configuration simplifies the sealing mechanisms associated with the stack manifolds because reactant streams are not directed between the separator plates and resilient MEA seals. Coolant passages may also be conveniently provided between adjoining non-active surfaces of the pairs of separator plates.

Abstract: A technique is disclosed for focus control of a beam of radiant energy, wherein a detector (712) of the beam has first (368) and second (376) outputs responsive to a position of the focal point of the beam. A circuit is coupled to the outputs of the detector for producing an error signal representing a displacement of the focus from a predetermined position, wherein the error signal has a periodic characteristic relative to the displacement. A servo (700) responsive to the error signal restores the displaced beam to the predetermined position. A local feedback loop (344) is coupled to the outputs of the detector, and includes first (360) and second (364) periodic function generators, each responsive to the error signal. The second periodic function generator has an output that differs from an output of the first periodic function generator by a phase angle, preferably 90 degrees. A first multiplier (332) multiplies the first output of the detector by the output of the first periodic function generator. A second multiplier (336) multiplies the second output of the detector by the output of the second periodic function generator, wherein the outputs (460, 472) of the first and second multipliers are provided as inputs (476, 480) of the circuit to modify the error signal.

Date Aug. 21, 1997A mixed culture reactor biologically removes organic pollution and nitrates by the anoxic route. The reactor includes a central stirred section having a lower part in which biological treatment of supplied raw water takes place. The central reactor section contains a suspension of an attached biomass of low concentration, in the order of a few grams per liter. At least one propelling screw is positioned within a jacket that is coaxially located in the reactor central section to ensure the circulation of the water to be treated. The water to be treated circulates in one direction within the jacket and in an opposite direction outside the jacket. The speed of circulation is selected so that bioparticles remain in suspension within the reactor central section. A release zone is located externally of the reactor central section and communicates with a lower part thereof. The water treated within the reactor central section escapes through the release zone, to the upper part of the central section, in accordance with an ascending current. This current has a speed such that the decantation speed of the bioparticles is greater than the speed of the water, and the speed of decantation of the excess biomass produced by biological reactions (denitrification in particular) is less than the speed of the water. Means are also included for enlarging a reactive zone at the lower part of the release zone.
