Title: A static mixer
Inventor: MANDIC ZDRAVKO
IPC: B01F5/00
Filed: 2004-03-08
Abstract: The static mixer (1) for a low viscosity fluid (20) contains inbuilt devices (10) effective for mixing, which are arranged in a pipe (3) or in a container conducting the fluid. The geometry of the inbuilt devices is largely that of a base structure. The inbuilt devices include structure elements (11, 11', 12) in the form of flat, folded or curved sheet metal-like flow obstacles as well as constrictions lying therebetween. A flow of the first order can be achieved by inbuilt devices in the form of the base structure and is a flow mixing the pipe contents globally in downstream mixing regions. The structure elements of the base structure can be described as segments, plates and/or vanes. The structure elements - called "primary flow obstacles" (11, 11', 12) in the following - are geometrically modified at surfaces and/or at edges. Local flows of the second order can be induced by these modifications which are superimposed on the flow of the first order and so improve the mixing quality. Radial and axial inhomogeneities in the fluid are namely better compensated than by the flow of the first order. Secondary flow obstacles (11a, 11a', 12a) form the modifications by which the turbulence is locally intensified and/or backflows are induced.

IPC: H04N21/242
Filed: 2002-09-09
Abstract: Aliasing and routing of plural MPEG data streams are disclosed. Disclosed apparatus embodiments include, e.g., a router or a cross-point switch that c an route data packets from any source location(s) to any destination location(s ). Such locations may be on multiple targets on a single processing board or ma y be on multiple boards in a chassis with a backplane linking the boards together. The disclosed aliasing and routing is achieved by processing MPEG data streams with associated Pills so they can be transported between communicatively linked locations. This is achieved by generating a PID alias table with plural PID aliases for each input data stream; by removing at lea st one PID from each input data stream to thereby produce filtered data streams ; by determining target destination(s) for each of the filtered data streams; and by buffering the filtered data streams so the filtered data streams can then be read and transported to respective target destination(s).

Abstract: This invention provides owners of swimming pools a floating aluminum frame assembly that will support the pool cover to eliminate water accumulation and make opening your pool less work.   The assembly varies by type of pool from round above ground pools, the oval or rectangular pools. For a round above ground pool it consists of an aluminum central hub that connects in a spider like fashion to eight legs that span out to the sides. These legs float on the surface of the water. Four of the legs are connected in a cross style fashion to another central hub for added support. Owners of the pool close their pool for the season in the same fashion and use their existing pool cover over the top of the structure. The main advantages are: .cndot. Eliminated stagnant water collection on the top of the pool. With concerns over West Nile Virus this is a positive. .cndot. Ease to open the pool in the spring season. .cndot. Utilizes existing pool cover and increases life. .cndot. Creates a safer more secure pool as it's hard to fall into a raised structure.   The entire structure is assembled with pins for ease of installation. All poles that span from the center to the sides are connected in the center for strength. While the structure is incredibly strong and secure, it becomes even stronger once the pool water freezes for the winter season. The Floating Pool Cover Support System is very easy to assemble and to disassemble. Configurations are available for all pools.

Inventor: CERMAK GERALD F
IPC: H04W64/00
Filed: 2004-07-02
Abstract: The present invention leverages changes in the sensed strength of radio signals at different locations to determine a device's location. In one instance of the present invention, inference procedures are used to process ambient commercial radio signals, to estimate a location or a probability distribution over the locations of a device. Tn another instance of the present invention, a system utilizes learning and inference methods that are applied to rank vector of signal strength vectors. Moving to such rank orderings leads to systems that bypass consideration of absolute signal strengths in location calculations. The present invention facilitates approximations for locating a device by providing a system that does not require a substantial number of available ambient signal strengths while still providing useful location inferences in determining locations.

IPC: H04N7/173
Filed: 2004-07-08
Abstract: A system and method for managing provisioning parameters in a cable network. A dynamic TFTP (DTFTP) server and a CMTS manage the provisioning of devices in a cable network. The DTFTP server and the CMTS share common provisioning parameters. A provisioning parameter has a name and a value. When channel are made in the value of a provisioning parameter that is also used by n CMTSs supported by that DTFTP server, the DTFTP server securely communicates the new provisioning parameter values to each such CMTS. In one embodiment of the present invention, the DTFTP server pushes the new provisioning parameter values to the CMTSs. In another embodiment of the present invention, a poller pulls the provisioning parameters from the DTFTP server to a central datastore where changes in provisioning parameters used by the CMTSs supported by the DTFTP are identified. The changed provisioning parameter values are pushed from the central datastore to the CMTSs.

Abstract: A method and system is disclosed for enabling full-service communications between a full-service cable modem termination system (fsCMTS) and a plurali ty of full-service cable modems (fsCM's) for a conventional two-way hybrid fibe r- coax (HFC) cable television network. Full-service communications include dat a, voice and video. Video includes broadcast quality MPEG-2 transport streams a nd Internet protocol media streams. A multi-channel full-service media-access- control (fsMAC) coordinates the access to the shared upstream and downstream channels. At lease two downstream channels and at least two upstream channel s are provided. Several MAC management messages are defined to enable multi- channel full-service MAC domain to be defined and to enable packet-by-packet true seamless channel change. Using the novel techniques described in this invention, multiple upstream channels can be used in various ways to best optimize the use of the spectrum for accommodating various quality-of-servic e needs of different type of services.

Title: Method and apparatus for resolving deadlock of auto-negotiation sequence between switches
Inventor: YAMAUCHI TOSHIRO
IPC: H04B10/00
Filed: 2004-09-29
Abstract: A transmission repeater has a function of recovery to normal out of the deadlock state of auto-negotiation sequence between switches. The switches exchange auto-negotiation configuration codes via first and second transmission repeaters for a state transition. The first transmission repeater monitors auto-negotiation configuration codes among data transmitted from the opposed switch, and when detecting more than a predetermined number of configuration codes of auto-negotiation having been transmitted during a given period of time, determines that the auto-negotiation sequence between the switches is at a deadlock, and reports it to the second transmission repeater , which then disconnects optical signals from the sending end of the second transmission repeater to the switch for more than twice the propagation time of signals between the switches, thus resolving the deadlock between the switches.

Title: Preferential oxidation reactor temperature regulation
Inventor: NORTHROP WILLIAM F
IPC: F28F9/02
Filed: 2003-06-13
Abstract: According to the present invention, a temperature profile within a preferential oxidation reactor is controlled using a two phase water/steam system to provide a temperature range within the reactor (10) which favors the selective oxidation of CO in a hydrogen rich reformate stream. The reformate is flowed in a mixture with oxygen over a preferential oxidation catalyst (17). The temperature profile is controlled by flowing a stream of water proximate to the preferential oxidation catalyst (17) so as the stream of water and the reformate stream passing over the catalyst (17) are in a heat transfer arrangement. The stream of water is maintained as a two phase stream from a point at which the water reaches its boiling temperature to a point proximate an outlet from which the stream of water exits the reactor (10).
